Bacterioplankton assemblages in coastal ponds reflect the influence of hydrology and geomorphological setting
Publisher: Oxford University Press (OUP)
Date: 15-05-2017
Abstract: The factors that shape microbial community assembly in aquatic ecosystems have been widely studied yet it is still unclear how distinct communities within a connected landscape influence one another. Coastal lakes are recipients of, and thus are connected to, both marine and terrestrial environments. Thus, they may host microbial assemblages that reflect the relative degree of influence by, and connectivity to, either system. In order to address this idea, we interrogated microbial community ersity at 49 sites in seven ponds in two seasons in the Lake MacLeod basin, a system fed by seawater flowing inland through underground karst. Environmental and spatial variation within ponds explain <9% of the community structure, while identity of the pond that s les were taken from explains 50% of community variation. That is, ponds each host distinct assemblages despite similarities in size, environment and position in the landscape, indicating a dominant role for local species sorting. The ponds contain a substantial amount of previously unknown microbial taxa, reflecting the unusual nature of this inland system. Rare marine taxa, possibly dispersed from seawater assemblages via the underground karst connection, are abundant within the inland system, suggesting an important role for regional dispersal within the metacommunities.

Evolution underground: A molecular phylogenetic investigation of Australian burrowing freshwater crayfish (Decapoda: Parastacidae) with particular focus on Engaeus Erichson
Publisher: Elsevier BV
Date: 03-2009
DOI: 10.1016/J.YMPEV.2008.11.025
Abstract: Phylogenetic relationships and species boundaries of Australian burrowing freshwater crayfish belonging to the genera Engaeus, Engaewa, Geocharax, Gramastacus and Tenuibranchiurus are investigated using combined mitochondrial and nuclear DNA sequence data and Bayesian and Maximum Parsimony methods. Phylogenies are statistically compared to previously published hypotheses. Engaeus, Engaewa, Geocharax, Gramastacus and Tenuibranchiurus form a strongly supported monophyletic clade. This grouping is independently supported by morphology but unites geographically highly disjunct lineages. Our data show two cryptic species in Geocharax, one cryptic species in Gramastacus and two cryptic species within the highly ergent Engaeus lyelli lineage. Using a Bayesian relaxed molecular clock method, the 16S rDNA data show generic-level ersification coinciding with the transition from a wet to arid palaeoclimate near the mid Miocene.

A review of landholder motivations and determinants for participation in conservation covenanting programmes
Publisher: Cambridge University Press (CUP)
Date: 03-2006
DOI: 10.1017/S0376892906002761
Abstract: Conservation covenants (or easements) are flexible but legally enforceable documents attached to a land title restricting the use of that land, providing for the protection of important conservation values, while allowing the landholder to retain possession. Given the attractiveness of covenants to those who seek to expand national and regional nature conservation initiatives, it is important to understand landholder motivations for participation in programmes that covenant for nature conservation. This paper examines the likely influences on landholder decision making when it comes to conservation initiatives. A review of literature highlights key motivations and determinants, such as landholder demographics and the nature of the land tenure in question, their knowledge and awareness of the programme, financial circumstances, and perceptions of financial and other risks and benefits of the programme itself, including incentives and compensation. Underpinning, or mediating, the decision-making processes will be landholder philosophies and values, and five constructs are determined from the review, namely economic dependence on property, private property rights, confidence in perpetual covenant mechanisms, nature conservation equity and nature conservation ethic. Using these constructs, a series of explicit hypotheses is drawn, applicable to agencies dealing with conservation covenants and testable through an adaptive management approach. A conceptual model is presented to show hypothesized relationships between motivational factors and the five constructs that will lead to the uptake of covenants by landholders, providing direction for policy makers and managers of incentive programmes for nature conservation on private lands.

Hippo/Mst1 Stimulates Transcription of the Proapoptotic Mediator NOXA in a FoxO1-Dependent Manner
Publisher: American Association for Cancer Research (AACR)
Date: 02-2011
DOI: 10.1158/0008-5472.CAN-10-2203
Abstract: The proapoptotic protein Noxa, a member of the BH3-only Bcl-2 protein family, can effectively induce apoptosis in cancer cells, although the relevant regulatory pathways have been obscure. Previous studies of the cytotoxic effects of α-tocopheryl succinate (α-TOS) on cancer cells identified a mechanism whereby α-TOS caused apoptosis requiring the Noxa-Bak axis. In the present study, ab initio analysis revealed a conserved FoxO-binding site (DBE DAF-16 binding element) in the NOXA promoter, and specific affinity of FoxO proteins to this DBE was confirmed by fluorescence anisotropy. FoxO1 and FoxO3a proteins accumulated in the nucleus of α-TOS–treated cells, and the drug-induced specific FoxO1 association with the NOXA promoter and its activation were validated by chromatin immunoprecipitation. Using siRNA knockdown, a specific role for the FoxO1 protein in activating NOXA transcription in cancer cells was identified. Furthermore, the proapoptotic kinase Hippo/Mst1 was found to be strongly activated by α-TOS, and inhibiting Hippo/Mst1 by specific siRNA prevented phosphorylation of FoxO1 and its nuclear translocation, thereby reducing levels of NOXA transcription and apoptosis in cancer cells exposed to α-TOS. Thus, we have demonstrated that anticancer drugs, exemplified by α-TOS, induce apoptosis by a mechanism involving the Hippo/Mst1-FoxO1-Noxa pathway. We propose that activation of this pathway provides a new paradigm for developing targeted cancer treatments. Cancer Res 71(3) 946–54. ©2011 AACR.

An ecological classification of the burrows of australian freshwater crayfish
Publisher: CSIRO Publishing
Date: 1986
DOI: 10.1071/MF9860237
Abstract: A classification of freshwater crayfish burrows, based on their relationship to the water-table, is presented. Burrows are ided into three classes, the third of which is apparently not found outside Australia and contains burrows which are independent of the water-table, receiving their water from surface run-off. The classification is compared with Hobbs classification of North American crayfish which is based on their burrowing behaviour.

Date: 23-02-2018
DOI: 10.1017/S0376892918000061
Abstract: Oceania can be characterized by a richness of culture, bio ersity and natural resources and a particular future that the changing climate will bring to islands, livelihoods and ecosystems. We reviewed literature detailing the limitations of siloed approaches to public health and conservation action for regional sustainability, highlighting opportunities for regional integration as place-based, through activities that are locally relevant, innovative engagement across a broader variety of sectors and working with indigenous peoples’ knowledges. We present three case studies that extend and redefine the boundaries of the fields of public health and conservation, enabling collaborators to better respond to complex issues impacting bio ersity and human health. These case studies make explicit the links between nutrition, catchment management, water resources, fisheries, marine protected areas and communicable and non-communicable diseases. Public health and conservation are more meaningfully connected in place-based, reciprocal and compassionate activities, using common language to draw on the well-developed instruments of both sectors. These will include health impact assessments and combine health and ecological economics, which together will contribute to responding to an emergent set of challenges, namely human population increase, urbanization, overfishing and more severe aspects of climate change.

Vulnerability of organic acid tolerant wetland biota to the effects of inorganic acidification
Publisher: Elsevier BV
Date: 03-2010
DOI: 10.1016/J.SCITOTENV.2010.01.034
Abstract: Inland waterbodies are often naturally acidic but are these ecosystems pre-adapted to inorganic acidification e.g., by acid sulfate soils (ASS)? We conducted a controlled mesocosm experiment with inorganically acidified wetland water and wetland sediment replicates to pH 3 from a naturally acidic (pH 3.9, conductivity=74microScm(-1)) wetland in south-western Australia. Following acidification, dissolved organic carbon and nitrogen declined, and chlorophyll a dropped to zero. Inorganic acidification mobilised metals from sediment sods with increased water concentrations of Cu, Fe, Mn, Ca, Mg and Al. Acidification showed no significant effect on diatom assemblage. Nonetheless, greatly reduced abundance and ersity of grazing zooplankton was observed. Macroinvertebrates generally showed abundance decreases, although filterer-collector taxa increased. Decreased primary production reduced functional ersity and consumer biomasses. These results suggest likely impact to ecosystem functioning of low pH, weakly-buffered and stained wetlands if exposed to inorganic acidification.
The role of allopatric speciation and ancient origins of Bathynellidae (Crustacea) in the Pilbara (Western Australia): Two new genera from the De Grey River catchment
Publisher: Brill
Date: 03-10-2019
DOI: 10.1163/18759866-20191412
Abstract: The stygofaunal family of Bathynellidae, is an excellent group to study the processes that shape ersity and distribution, since they have unknown surface or marine relatives, high level of endemism, and limited dispersal abilities. Recent research on Bathynellidae in Western Australia (Pilbara) has uncovered new taxa with unexpected distributions and phylogenetic relationships, but the biogeographical processes that drive their ersification on the continent are still unclear. By exploring the ersity, distribution, and ergence time of Bathynellidae in a setting such as the perched and isolated aquifers of the Cleaverville Formation in the north of the De Grey River catchment (Pilbara), we aim to test the hypothesis that vicariance has shaped the distribution of this family, specifically if one or multiple vicariant events were involved. We analysed the specimens collected from perched water in different plateaus of the Cleaverville Formation, combining morphological and molecular data from mitochondrial and nuclear genes. We described two new species and genera ( Anguillanella callawaensis gen. et sp. nov. and Muccanella cundalinensis gen. et sp. nov.), and two additional taxa are recognised using morphology and/or Automatic Barcode Gap Discovery and Poisson Tree Processes species delimitation methods. New genera and species result restricted to isolate perched aquifers on single plateaus and their distributions, phylogenetic relationships, and ergence time estimates support multiple vicariant events and ancient allopatric speciation.
A taxonomic revision of species in the freshwater crayfish genus Engaeus Erichson (Decapoda: Parastacidae)
Publisher: CSIRO Publishing
Date: 1990
DOI: 10.1071/IT9900427
Abstract: In a revision of the species in the genus Engaeus, the number of species is increased to thirty-four, resulting from the addition of fourteen new species, nine of them endemic to Tasmania (E. disjuncticus, E. granulatus, E. lengana, E. mairener, E. martigener, E. nulloporius, E. orramakunna, E, spinicaudatus and E. tayatea), and five endemic to Victoria (E. curvisuturus, E. karnanga, E. mallacoota, E. merosetosus and E. rostrogaleatus). Four species have been synonymised: E. jumbunna with E. hemicirratulus, E. connectus with E. tuberculatus, E. marmoratus with E. quadrimanus, and E. parvulus with E. cymus. A key to species is provided. For all species are given synonymies, a diagnosis, a discussion of morphological variation, notes on life histories and general ecology, and distribution.
Water, ecology and health: Ecosystems as settings for promoting health and sustainability
Publisher: Oxford University Press (OUP)
Date: 12-11-2009
Abstract: Despite the proposed ecological and systems-based perspectives of the settings-based approach to health promotion, most initiatives have tended to overlook the fundamental nature of ecosystems. This paper responds to this oversight by proposing an explicit re-integration of ecosystems within the healthy settings approach. We make this case by focusing on water as an integrating unit of analysis. Water, on which all life depends, is not only an integral consideration for the existing healthy settings (schools, hospitals, workplaces) but also highlights the ecosystem context of health and sustainability. A focus on catchments (also know as watersheds and river basins) exemplifies the scaled and upstream/downstream nature of ecosystems and draws into sharp focus the cross-sectoral and transdisciplinary context of the social and environmental determinants of health. We position this work in relation to the converging agendas of health promotion and ecosystem management at the local, regional and global scales--and draw on evidence from international initiatives as erse as the WHO Commission on Social Determinants of Health, and the Millennium Ecosystem Assessment. Using water as a vehicle for understanding the systemic context for human wellbeing, health promotion and disease prevention draws inevitable attention to key challenges of scale, intersectoral governance and the complementary themes of promoting resilience and preventing vulnerability. We conclude by highlighting the importance of building in idual and institutional capacity for this kind of integration--equipping a new generation of researchers, practitioners and decision-makers to be conversant with the language of ecosystems, capable of systemic thought and focused on settings that can promote both health and sustainability.

Transforming place-based management within watersheds in Fiji: the Watershed Interventions for Systems Health project
Publisher: California Digital Library (CDL)
Date: 10-02-2023
DOI: 10.31223/X56S9M
Abstract: Watersheds offer opportunities for place-based interventions to transform systems health via preventative versus reactive approaches to management that achieve multiple co-benefits for public and environmental health. The Watershed Interventions for Systems Health in Fiji (WISH Fiji) project embraced participatory knowledge co-production and action-oriented research to identify risks to public and ecosystem health, prioritize interventions to address risks, and monitor responses of the system to interventions. We used screening filters and local knowledge to collaboratively identify five watersheds for action with high prior incidence of water-related diseases (Fiji& rsquor s & three plagues& of leptospirosis, typhoid and dengue) and high risk to downstream environmental health. We reviewed literature to identify disease risk factors, evaluated overlaps with risks for downstream environmental impact, and designed 13 instruments to collect information about baseline risk. Following consultations to obtain free, prior and informed consent, we enrolled 311 households across 29 communities. We synthesized data to identify key risks at the household, community, and landscape level, which were communicated to community water and resource management committees and government leaders as part of developing water and sanitation safety plans for each community. Local committees identified 339 priority risk reduction actions across nine main categories: animal management drainage health systems surveillance hygiene integrated planning land use management sanitation systems waste management and water systems. As of October 2022, 154 interventions were implemented in the five watersheds across different risk categories and scales. While we can track changes to factors that reduce risk of water-related disease and improve environmental health, direct evaluation of impacts to public health is limited due to poor geolocation of case records. The WISH Fiji project is a model of cross-sectoral coordination that efficiently progresses multiple Sustainable Development Goals, but scaling requires sustained investment in interventions to realize full benefits, particularly for nature-based solutions that exhibit lagged responses.

Regeneration time: ancient wisdom for planetary wellbeing
Publisher: Cambridge University Press (CUP)

DOI: 10.1017/AEE.2021.34
Abstract: In these regenerative times prompted by the Anthropocene, Aboriginal voices are situated to draw on ancient wisdom for local learning and to share information across the globe as ecological imperative for planetary wellbeing. In this paper, postqualitative research foregrounds the sentient nature of life as ancestral power and brings the vitality of co-becoming as our places into active engagement. It enables coloniality to surface and reveals how it sits in our places and lives, in plain sight but unnoticed because of its so-called common sense. Postqualitative research relates with ancient knowledges in foregrounding Country’s animacy and presence, revealing the essence of time as non-linear, cyclical and perpetual. In this way, we are places, weather and climate, not separate. Postqualitative research also relates with ancient knowledge in illustrating Country as agentic and time as multiple, free of constraint and directly involved in our everyday. Country is active witness in the lives of Aboriginal peoples, here always. This is a strong basis for decolonisation. We all have a responsibility to listen, to help create a new direction for the future in the present time.

Intertwined Strands for Ecology in Planetary Health
Publisher: MDPI AG
Date: 14-03-2019
Abstract: Ecology is both blessed and burdened by romanticism, with a legacy that is multi-edged for health. The prefix ‘eco-’ can carry a cultural and political (subversive) baggage, associated with motivating environmental activism. Ecology is also practiced as a technical ‘science’, with quantitative and deterministic leanings and a biophysical emphasis. A challenge for planetary health is to avoid lapsing into, or rejecting, either position. A related opportunity is to adopt ecological thought that offers a rich entrance to understanding living systems: a relationality of connectedness, interdependence, and reciprocity to understand health in a complex and uncertain world. Planetary health offers a global scale framing we regard its potential as equivalent to the degree to which it can embrace, at its core, ecological thought, and develop its own political narrative.

Parasites, ecosystems and sustainability: An ecological and complex systems perspective
Publisher: Elsevier BV
Date: 06-2005
DOI: 10.1016/J.IJPARA.2005.03.002
Abstract: Host-parasite relationships can be conceptualised either narrowly, where the parasite is metabolically dependent on the host, or more broadly, as suggested by an ecological-evolutionary and complex systems perspective. In this view Host-parasite relationships are part of a larger set of ecological and co-evolutionary interdependencies and a complex adaptive system. These interdependencies affect not just the hosts, vectors, parasites, the immediate agents, but also those indirectly or consequentially affected by the relationship. Host-parasite relationships also can be viewed as systems embedded within larger systems represented by ecological communities and ecosystems. So defined, it can be argued that Host-parasite relationships may often benefit their hosts and contribute significantly to the structuring of ecological communities. The broader, complex adaptive system view also contributes to understanding the phenomenon of disease emergence, the ecological and evolutionary mechanisms involved, and the role of parasitology in research and management of ecosystems in light of the apparently growing problem of emerging infectious diseases in wildlife and humans. An expanded set of principles for integrated parasite management is suggested by this perspective.

Fire suppression and burnt sediments: effects on the water chemistry of fire-affected wetlands
Publisher: CSIRO Publishing
Date: 2012
DOI: 10.1071/WF10125
Abstract: Preventing fire from entering wetland areas during seasonal or prolonged drought, or suppressing fire once it has entered a wetland, requires consideration of the consequences of the fire-management action on water quality. Two approaches can be taken to suppress such fires: chemical fire retardants or the flooding of sediments. We determine a lack of information relating to the effects of these approaches for water quality within fire-affected wetlands. The aim of this study was to gain a preliminary understanding of the effects of three treatments: two chemical treatments and saturation. Microcosms were established to test sediments from a wetland on the Swan Coastal Plain, Western Australia, which were exposed to temperatures ranging from 30 to 800°C. The results indicate that one of the fire-retardant chemicals increased the soluble nutrient load present in the water column, as predicted by the results of other research. However, the same chemical had a minor but important effect as an acidity buffer when the organic, pyritic sediment was heated but not burnt. The second chemical treatment did not increase the nutrient load but neither did it buffer the acidity generated by the heating and burning of the organic sediment. It was virtually indistinguishable from the saturation treatment in this regard.
Assessment of post-wildfire erosion risk and effects on water quality in south-western Australia
Publisher: CSIRO Publishing
Date: 2020
DOI: 10.1071/WF18123
Abstract: Investigations of wildfire impact on water resources have escalated globally over the last decade owing to an awareness of climate-related vulnerabilities. Within Australia, research into post-wildfire erosion has focused on water supply catchments in the south-eastern region. Here, we examine post-wildfire erosion risk and its potential for water quality impacts in a catchment in south-western Australia. The catchment of the Harvey River, which drains from forested escarpments onto an agricultural coastal plain and into valuable coastal wetlands, was burnt by wildfire in 2016. The aims of this study were to determine erosion risk across contrasting landforms and variable fire severity, using the Revised Universal Soil Loss Equation (RUSLE), and to determine whether post-fire water quality impacts could be detected at permanent river monitoring stations located on the coastal plain. RUSLE outputs showed erosion hot-spots at intersections of steep terrain and high fire severity and that these areas were confined to forested headwaters and coastal dunes. Monthly water quality data showed conspicuous seasonal patterns, but that s ling frequency was temporally too coarse to pick up predicted event-related effects, particularly given that the pre-existing monitoring sites were distal to the predicted zone of contamination.
Knowledge that acts: evaluating the outcomes of a knowledge brokering intervention in Western Australia's Ningaloo region
Publisher: Springer Science and Business Media LLC
Date: 19-08-2017
DOI: 10.1007/S00267-017-0917-1
Abstract: Knowledge exchange involves a suite of strategies used to bridge the ides between research, policy and practice. The literature is increasingly focused on the notion that knowledge generated by research is more useful when there is significant interaction and knowledge sharing between researchers and research recipients (i.e., stakeholders). This is exemplified by increasing calls for the use of knowledge brokers to facilitate interaction and flow of information between scientists and stakeholder groups, and the integration of scientific and local knowledge. However, most of the environmental management literature focuses on explicit forms of knowledge, leaving unmeasured the tacit relational and reflective forms of knowledge that lead people to change their behaviour. In addition, despite the high transaction costs of knowledge brokering and related stakeholder engagement, there is little research on its effectiveness. We apply Park's Manag Learn 30(2), 141-157 (1999) Knowledge and Participatory Research, London: SAGE Publications (2006) tri-partite knowledge typology as a basis for evaluating the effectiveness of knowledge brokering in the context of a large multi-agency research programme in Australia's Ningaloo coastal region, and for testing the assumption that higher levels of interaction between scientists and stakeholders lead to improved knowledge exchange. While the knowledge brokering intervention substantively increased relational networks between scientists and stakeholders, it did not generate anticipated increases in stakeholder knowledge or research application, indicating that more prolonged stakeholder engagement was required, and/or that there was a flaw in the assumptions underpinning our conceptual framework.
Wetlands as social ecological systems, and relationality in the policy domain
Publisher: CSIRO Publishing
Date: 19-07-2022
DOI: 10.1071/MF22018
Abstract: A wetland policy perspective based on social ecological systems accepts that wetlands are part of landwaterscapes, that people are part of wetland ecosystems, and that the health of wetlands and the health of people are interdependent, evidence of the close, reciprocal and in isible relationships between nature and culture. These relationships are storied and place-based, associated with place attachment, and are representations of relational values. They are most easily located wherever and whenever Indigenous and local peoples’ knowledge and interests are at play in wetland settings. Legal and administrative processes that recognise Chthonic law and rights for wetlands will elevate relational values and provide the governance arrangements for their inclusion in wetland (and other ecosystem) management. Co-designing with Indigenous and local communities in developing wetland policies and operationalising practices will allow for wetland stories to be shared, respectfully cared for, and built into educational curricula and ecosystem valuation models.

Human exposure to metals in groundwater affected by acid sulfate soil disturbance
Publisher: Springer Science and Business Media LLC
Date: 29-07-2008
DOI: 10.1007/S00244-007-9076-3
Abstract: The disturbance and oxidation of sulfidic soils can cause an increase in acidity resulting in the mobilization of high concentrations of metals in groundwater or connected surface water. This is an increasing problem in urban areas of Australia and internationally. We hypothesized that the risks of exposure to contaminated water would be increased by this phenomenon. We undertook a preliminary investigation of human exposure to metals recruiting 27 residents in an acid sulfate soil-affected area, 21 residents using a bore (groundwater) for home-grown produce irrigation, and 6 residents who did not. Participants completed a questionnaire and provided a s le of urine (first morning void), toenails (from all 10 toes), hair, and borewater. Only hair metal concentrations were higher in those using bore water and ranged from below detection (<DL) to 38 mg/kg Al <DL = 0.07 mg/kg As, 0.02-0.57 mg/kg Cd, 0.19-4.3 mg/kg Pb, 11-160 mg/kg Cu, and 99-280 mg/kg Zn. The data indicate exposure to metals in bore-water users might be occurring and further investigation is warranted even though the concentrations recorded in this study are considered low.

Local Challenges and Successes Associated with Transitioning to Sustainable Food System Practices for a West Australian Context: Multi-Sector Stakeholder Perceptions
Publisher: MDPI AG
Date: 10-06-2019
Abstract: Large-scale food system practices have diminished soil and water quality and negatively impacted climate change. Yet, numerous opportunities exist to harness food system practices that will ensure better outcomes for human health and ecosystems. The objective of this study was to consider food Production, Processing, Access and Consumption domains, and for each determine the challenges and successes associated with progressing towards a sustainable food system. A workshop engaging 122 participants including producers, consultants, consumers, educators, funders, scientists, media, government and industry representatives, was conducted in Perth, Western Australia. A thematic analysis of statements (Successes (n = 170) or Challenges (n = 360)) captured, revealed issues of scale, knowledge and education, economics, consumerism, big food, environmental/sustainability, communication, policies and legislation, and technology and innovations. Policy recommendations included greater investment into research in sustainable agriculture (particularly the evidentiary basis for regenerative agriculture), land preservation, and supporting farmers to overcome high infrastructure costs and absorb labour costs. Policy, practice and research recommendations included focusing on an integrated food systems approach with multiple goals, food system actors working collaboratively to reduce challenges and undertaking more research to further the regenerative agriculture evidence.

Abstract: There are numerous localized peat deposits on the Swan Coastal Plain, an urban and rural bioregion otherwise dominated by wetland ecosystems in southwestern Australia. Hydrological change is significant in the bioregion: urban development encroaches on wetlands, groundwater extraction provides the city population with most of its water, and rainfall declines will not recharge aquifers in the future. The wetland processes which contribute to the formation of these peat deposits have therefore changed and are becoming vulnerable to fire events with residents increasingly exposed to peat smoke. There is an imperative to characterise this peat smoke to determine if exposures are harmful or toxic, and opportunities to do so in this setting arise due to the absence of bushfire smoke which has confounded other international studies. We have measured volatile organic compounds (VOCs) and particulate concentrations from an opportunistic assessment of two peat fires. SUMMA canister grab s les and a portable GCMS were used to determine the VOCs with high 1h benzene concentrations of 16 and 30 ppm v/v. PM10 and PM2.5 particulate data were collected using an Osiris continuous analyser with 24h concentrations recorded at varying time periods (within a 5 months timeframe) ranging from 1h maximums of between 23-37 microgm(-3) for PM10 and 50.5-106 microgm(-3) for PM2.5. While the 24h averages were generally below national air quality standards, elevated 1h concentrations were observed on numerous occasions and on most days. Given the proximity of residential development to many peat deposits, a drying climate and the increased risk of arson in peri-urban environments, the health impacts of exposure to peat smoke need to be determined and if necessary measures developed to prevent exposure (which would include maintaining wetland sediment integrity so as to reduce its vulnerability to fire).

Performing kayepa dordok living waters in Noongar boodjar, South‐Western Australia
Publisher: Wiley
Date: 28-09-2021
DOI: 10.1002/RRA.3868
Abstract: Performance through language, song and dance provides alternative knowledges and ways of understanding, in this case, developing deeper relationships with living water. Drawing on Indigenous Noongar culture from south‐western Australia, this paper addresses the question: How can relationships between living underground, estuarine and riverine water bodies ( kayepa dordok ) be performed? Two new interlinked Noongar works in response to local riverscapes were developed for, and performed as part of, the 2021 Perth Festival. The first was to embody the return journey of the bullshark, from the salt water to the riverine fresh water the second was to enact the presence of the unseen groundwater – which emerges as wetlands and estuaries strewn throughout the landscape – on its return to the sea. The method used to derive the song and dance, and the impact of the performance itself, are described. The experiment makes a case for multiple benefits associated with re‐establishing connections among culture and nature by drawing on Indigenous perspectives, through performance giving voice to a relationality between river systems and people.
A review of measures used to examine medication adherence in people with ADHD at initiation, implementation and discontinuation of pharmacotherapy

DOI: 10.1016/J.SAPHARM.2019.06.001
Abstract: Adherence to prescribed medication is a dynamic process that changes over time. Whilst several measures have been used to examine adherence in patients with ADHD, it is not clear how these measures have been used to measure adherence in the context of its three phases (initiation, implementation, discontinuation). To examine measures used to assess medication adherence at its three phases in people with ADHD. The PRISMA guidelines were followed for this review. Six databases (Medline, PubMed, IPA, CINAHL, Embase, and PsycINFO) were systematically searched in October 2018, without any limitations on the start dates. Keywords reflecting three broad concepts (adherence, ADHD and measures) were used as part of the search strategy. Studies that assessed medication adherence in people with ADHD and described methods used to assess adherence were selected for this review. Forty-nine studies were included. Most (69.3%) examined adherence at the implementation phase. Claims databases, self-reported questionnaires, and prescription-refill records were used to measure adherence at the initiation, implementation, and discontinuation phase, respectively. Overall, self-reported questionnaires were the most frequently used measure at the implementation phase, but the psychometric properties were not reported in almost half of the studies that used these measures. Initiation and discontinuation phases of adherence have been relatively less examined in people with ADHD. Although self-reported questionnaires were the commonly used measures, the validity and reliability of these measures are of concern in guiding evidence-based practice. Measures with improved psychometric properties are needed that can examine adherence across its three phases.

Health at the Sub-catchment Scale: Typhoid and Its Environmental Determinants in Central Division, Fiji
Publisher: Springer Science and Business Media LLC
Date: 24-08-2016
DOI: 10.1007/S10393-016-1152-6
Abstract: The impact of environmental change on transmission patterns of waterborne enteric diseases is a major public health concern. This study concerns the burden and spatial nature of enteric fever, attributable to Salmonella Typhi infection in the Central Division, Republic of Fiji at a sub-catchment scale over 30-months (2013-2015). Quantitative spatial analysis suggested relationships between environmental conditions of sub-catchments and incidence and recurrence of typhoid fever. Average incidence per inhabited sub-catchment for the Central Division was high at 205.9/100,000, with cases recurring in each calendar year in 26% of sub-catchments. Although the numbers of cases were highest within dense, urban coastal sub-catchments, the incidence was highest in low-density mountainous rural areas. Significant environmental determinants at this scale suggest increased risk of exposure where sediment yields increase following runoff. The study suggests that populations living on large systems that broaden into meandering mid-reaches and floodplains with alluvial deposition are at a greater risk compared to small populations living near small, erosional, high-energy headwaters and small streams unconnected to large hydrological networks. This study suggests that anthropogenic alteration of land cover and hydrology (particularly via fragmentation of riparian forest and connectivity between road and river networks) facilitates increased transmission of typhoid fever and that environmental transmission of typhoid fever is important in Fiji.
Detecting Sex-Related Changes to the Metabolome of a Critically Endangered Freshwater Crayfish During the Mating Season

DOI: 10.3389/FMOLB.2021.650839
Abstract: Captive breeding is a vital tool in the conservation of highly endangered species, as it is for the Margaret River hairy marron, Cherax tenuimanus , from the south west of Australia. A close relative, Cherax cainii , has almost completely displaced C. tenuimanus in the wild and is a successful aquaculture species, whereas C. tenuimanus has performed poorly in captivity. We used untargeted liquid chromatography-mass spectrometry to obtain metabolomic profiles of female and male C. tenuimanus held in controlled aquarium conditions during their reproductive period. Using repeated haemolymph s ling we tracked the metabolomic profiles of animals just prior to and for a period of up to 34 days after pairing with a similar sized potential mate. We identified 54 reproducible annotated metabolites including amino acids, fatty acids, biogenic amines, purine and pyrimidine metabolites and excretion metabolites. Hierarchical clustering analysis distinguished five metabolite clusters. Principal component-canonical variate analysis clearly distinguished females from males, both unpaired and paired similar trends in profile changes in both sexes after pairing and a striking shift in males upon pairing. We discuss three main patterns of metabolomic responses: differentiation between sexes reactive responses to the disturbance of pairing and convergent response to the disturbance of pairing for males. Females generally had higher concentrations of metabolites involved in metabolic rate, mobilisation of energy stores and stress. Responses to the disturbance of pairing were also related to elevated stress. Females were mobilising lipid stores to deposit yolk, whereas males had a rapid and strong response to pairing, with shifts in metabolites associated with gonad development and communication, indicating males could complete reproductive readiness only once paired with a female. The metabolomic profiles support a previously proposed potential mechanism for displacement of C. tenuimanus by C. cainii in the wild and identify several biomarkers for testing hypotheses regarding reproductive success using targeted metabolomics.

More evolution underground: Accelerated mitochondrial substitution rate in Australian burrowing freshwater crayfishes (Decapoda: Parastacidae)

DOI: 10.1016/J.YMPEV.2017.09.022
Abstract: To further understand the evolutionary history and mitogenomic features of Australia's highly distinctive freshwater crayfish fauna, we utilized a recently described rapid mitogenome sequencing pipeline to generate 24 new crayfish mitogenomes including a ersity of burrowing crayfish species and the first for Astacopsis gouldi, the world's largest freshwater invertebrate. Whole mitogenome-based phylogeny estimates using both Bayesian and Maximum Likelihood methods substantially strengthen existing hypotheses for systematic relationships among Australian freshwater crayfish with evidence of pervasive ersifying selection and accelerated mitochondrial substitution rate among the members of the clade representing strongly burrowing crayfish that may reflect selection pressures for increased energy requirement for adaptation to terrestrial environment and a burrowing lifestyle. Further, gene rearrangements are prevalent in the burrowing crayfish mitogenomes involving both tRNA and protein coding genes. In addition, duplicated control regions were observed in two closely related Engaeus species, together with evidence for concerted evolution. This study significantly adds to the understanding of Australian freshwater crayfish evolutionary relationships and suggests a link between mitogenome evolution and adaptation to terrestrial environments and a burrowing lifestyle in freshwater crayfish.

Water quality and macroinvertebrate response to acidification following intensified summer droughts in a Western Australian wetland
Publisher: CSIRO Publishing
Date: 2001
DOI: 10.1071/MF00021
Abstract: A decline in pH from ˜6 –8 to ˜4 –5 over a period of 4 years was detected during routine monitoring of surface waters at Lake Jandabup.This was accompanied by lower water levels,shorter periods of inundation and measurable changes in other attributes of the water:sulfate,iron and ammonium concentrations increased markedly,and filterable reactive phosphorus and colour (gilvin)decreased.Macroinvertebrate family richness did not change notably over this period,but there were shifts in community structure:ostracods,isopods and oligochaete worms became less abundant hipods,mayflies and gastropods disappeared,while ceratopogonids (Diptera)and macrothricid cladocerans increased in abundance.Historical evidence suggests that at least one other acidification event has occurred in the recent past.Mechanisms associated with the acidification,and the wetland ’s capacity to recover from such events,are discussed.

Acid sulphate soil disturbance and metals in groundwater: Implications for human exposure through home grown produce
Publisher: Elsevier BV
Date: 09-2006
DOI: 10.1016/J.ENVPOL.2005.11.014
Abstract: A significant emerging environmental problem is the disturbance and oxidation of soils with high levels of iron sulphide minerals resulting in acidification and causing the mobilization of metals into groundwater. This process is occurring in many parts of the world. In Western Australia, impacted groundwater is extracted by residents for domestic use. We sought to establish domestic use patterns of bore water and the concentration of metals. Sixty-seven domestic bore water s les clearly indicated oxidation of sulphidic materials with heavy metal concentrations ranging for aluminium (<DL-37.0 mg/L), arsenic (<DL-6.6 mg/L), iron (<DL-1200 mg/L), cadmium (<DL-0.021 mg/L), lead (<DL-0.040 mg/L), selenium (<DL-0.006 mg/L). A high proportion of residents used bore water on home grown produce. The study suggests that there is potential for human exposure to heavy metals via the consumption of home grown produce. This warrants further investigation in light of increasing acid sulphate soil disturbance in many locations.

Understanding subterranean variability: The first genus of Bathynellidae (Bathynellacea, Crustacea) from Western Australia described through a morphological and multigene approach
Publisher: CSIRO Publishing
Date: 2018
DOI: 10.1071/IS17004
Abstract: The number of subterranean taxa discovered in the north of Western Australia has substantially increased due to the requirements for environmental surveys related to mining development. Challenges in estimating subterranean bio ersity and distributions are related to lack of knowledge of taxa with convergent morphological characters in a largely unobservable ecosystem setting. An integrated approach is warranted to understand such complexity. Bathynellidae occur in most Australian aquifers, but only one species has been described so far, and the group lacks a reliable taxonomic framework. A new genus and one new species from the Pilbara region of Western Australia, Pilbaranella ethelensis, gen. et sp. nov., is described using both morphological and molecular data. Three additional species of Pilbaranella are defined through mitochondrial and nuclear genes, using Automatic Barcode Gap Discovery and Poisson Tree Processes species delimitation methods. A comparison of morphology and 18S rRNA sequences between Pilbaranella, gen. nov. and known lineages provides the evidentiary basis for the decision to establish a new genus. This study provides a morphological and molecular framework to work with Bathynellidae, especially in Australia where a highly erse fauna remains still undescribed.

DOI: 10.1007/S10393-014-0952-9
Abstract: Access to parks and green spaces within residential neighbourhoods has been shown to be an important pathway to generating better physical and mental health for in iduals and communities. Early research in this area often failed to identify specific attributes that contributed to reported health outcomes, with more recent research focused on exploring relationships between health outcomes and aspects of access and design. A mixed methods research project conducted in Perth, Western Australia examined the role that neighbourhood green space played in influencing residents' self-reported health status, and this paper identifies significant relationships found between perceptions of green space quality and self-reported health. It focuses on the factors that were found to be most positively associated with better health outcomes: proximity, retention, useability and visitation of neighbourhood green space.

Perceptions of drinking water access and quality in rural indigenous villages in Fiji
Publisher: IWA Publishing
Date: 03-2022
DOI: 10.2166/WPT.2022.022
Abstract: Poor rural water quality is a health challenge in Fiji. A mixed-methods study in six iTaukei (Indigenous Fijian) villages was conducted to understand local perceptions of drinking water access and quality, how this changes drinking water source choices, and impacts of age and gender. Seventy-two household surveys, 30 key informant interviews (KIIs) and 12 focus group discussions (FGDs) were conducted. Household surveys revealed 41.7% of community members perceived their water as dirty and 76.4% perceived their water as clean. Two-thirds of households reported that they always or usually had enough water. FGDs and KIIs revealed water access and quality was influenced by population size, seasonality, and rainfall. Perceptions of water quality caused villages to shift to alternative water sources. Alignment of the qualitative and quantitative data identified four themes: sources and infrastructure, access, quality and contamination. There was mixed alignment of perceptions between access and quality between the household surveys, and KIIs and FGDs with partial agreement sources and infrastructure, and quality. Gender was found to influence perceptions of dirty water, contamination, and supply and demand. Perceptions of water quality and access shape decisions and choices for water sources and can be used to inform resilience and inclusive water strategies.

Biogenic processes or terrigenous inputs? Permanent water bodies of the Northern Ponds in the Lake MacLeod basin of Western Australia
Publisher: CSIRO Publishing
Date: 2017
DOI: 10.1071/MF16233
Abstract: The saline wetlands of the Northern Ponds, Lake MacLeod, contravene general classifications for salt lakes because, despite enduring high levels of evaporation, they contain permanently inundated ponds that are continually supplied with seawater by a seepage face from the Indian Ocean. The present study investigated the physical, sediment and chemical characteristics of these ponds, using sonar, flow-rate measurements, microscopy and inductively coupled plasma–mass spectrometry to understand the role of biogenic and terrigenous inputs on the benthic habitats. The chemical composition of the water bodies did not differ significantly from the seawater feedstock, which facilitates biogenic sediment accumulation. The largest permanent water body differs from the other ponds in physical and chemical structure, in that, possibly because of its size, it is dominated by terrigenous inputs, which result in higher nutrient concentrations and non-biogenic sediments. The Northern Ponds represent a system where the hydrology permits the establishment of permanent wetlands in an arid environment. Because of the constant supply of seawater, the ponds have a blend of habitat characteristics from marine and other inland salt-lake environments. The present study showed that a ‘marine-like’ state can override more typical characteristics of inland water bodies where discharge rates are high and water-residence times are low.

Sea-level fluctuations and the distributions of some freshwater crayfishes of the genus engaeus (Decapoda; parastacidae) in the bass strait area
Publisher: CSIRO Publishing
Date: 1988
DOI: 10.1071/MF9880497
Abstract: The effect of past sea-level fluctuations on the distribution of one species of freshwater crayfish, Engaeus cunicularius, which occurs in coastal areas on both sides of Bass Strait and on several Bass Strait islands, is discussed. A model is proposed to explain the way in which successive rising and falling of sea levels has contributed to the distributions and speciation of some species in the genus Engaeus, and the implications of the model are outlined. Bass Strait is not considered to have acted as a complete barrier to freshwater organisms during periods of lowered sea levels.

Cryptic diversity in Engaeus Erichson, Geocharax Clark and Gramastacus Riek (Decapoda : Parastacidae) revealed by mitochondrial 16S rDNA sequences
Publisher: CSIRO Publishing
Date: 2007
DOI: 10.1071/IS07019
Abstract: Nucleotide sequence data from the mitochondrial 16S rDNA region were utilised to investigate phylogenetic relationships and species boundaries among Australian freshwater crayfish belonging to the genera Engaeus Erichson, 1846, Geocharax Clark, 1936 and Gramastacus Riek, 1972. Geocharax and Gramastacus were found to be monophyletic genera but one species currently assigned to Engaeus may belong to another genus. Relationships between the three existing genera were not resolved. Analysis of species boundaries within Geocharax suggests that there are an additional two species in this genus, and our analysis of Gramastacus indicates that undescribed populations from central New South Wales may comprise a second species. The data provide at least one instance of a taxon crossing the Great Dividing Range and provide confirmation of previously proposed hypotheses seeking to explain trans-Bass Strait distributions of species.
Bacterial and ciliate biofilm community structure at different spatial levels of a salt lake meta-community
Publisher: Oxford University Press (OUP)
Date: 03-08-2018
Abstract: Meta-communities are assembled along an ecological scale that determines local and regional ersity. Spatial patterns have been detected in planktonic bacterial communities at distances <20 m, but little is known about the occurrence of similar variation for other microbial groups and changes in microbial meta-community assembly at different levels of a meta-community. To examine this variation, the biofilm of eight saline ponds were used to investigate processes shaping ersity within ponds (β) and between ponds (δ). Bacterial and ciliate communities were assessed using ARISA and T-RFLP respectively, while ersity partitioning methods were used to examine the importance of taxonomic turnover and variation partitioning was used to distinguish spatial from environmental determinants. The results show that turnover is important for determining β- and δ- ersity of biofilms. Spatial factors are important drivers of bacterial β- ersity but were unimportant for ciliate β- ersity. Environmental variation was a strong determinant of bacterial and ciliate δ- ersity, suggesting sorting processes are important for assembling pond communities. Determinants of ersity in bacteria are not universal for ciliates, suggesting higher functional redundancy of bacteria or the greater niche breadth of ciliates may be important in discriminating assembly processes between the two organisms.

Wetland invertebrate richness and endemism on the Swan Coastal Plain, Western Australia
Publisher: CSIRO Publishing
Date: 2009
DOI: 10.1071/MF08204
Abstract: Regional assessments of inland aquatic biota, determined from compilations of mostly descriptive and distributional data, can reveal information to justify local, regional or even global conservation priorities. In the present study, a regional assessment of the wetlands of the Swan Coastal Plain (SCP), Western Australia, was conducted to test the hypothesis that the relatively recent (in geological terms) formation of the wetlands has yielded relatively homogeneous aquatic assemblages. A compilation of aquatic invertebrate taxa from 18 studies of 66 wetlands has shown a surprisingly rich fauna (considering the comparatively small survey area and the degree of anthropogenic alteration of the SCP). Some of this richness is associated with increased s ling effort and proximity to other wetlands, and the habitat complexity and degree of permanence of the wetlands has contributed to richness, community assemblage composition, rarity and endemism patterns. Although taxonomically rich, local and regional endemism is relatively low compared with other regional assessments. The caves and the springs of the bioregion have a distinctive faunal assemblage however, the assemblages of surface water wetlands do appear more homogeneous. Although iconic wetlands demand priorities for conservation action, management should be directed at the entire suite of wetlands to ensure wetland ecosystem integrity.

DOI: 10.1108/IJSHE-09-2013-0111
Abstract: – Academic approaches to the challenge of enhancing sustainability in research in university contexts illustrate that universities are affected by the very same values and socio-ecological issues they set out to address, making transformation difficult at every level. A theoretical and practical framework designed to facilitate cultural transformation is therefore necessary for conceptualising the problem and delineating possible strategies to enhance sustainability in research. Organisational change is also required, possibly on a university-by-university basis, where cross-institutional learning may be possible with personal behaviours that enhance collaboration across disciplinary and administrative ides. – This paper contends that action research, in particular, community action research (CAR), offers the best approach to this task because it focusses on learning and change, and these are both essential to cultural transformation. A case study from a university in Western Australia is used to demonstrate this approach. – The case study analysis shows some evidence for the presence of knowledge for organisational transformation, and that future monitoring cycles will be needed to detect the extent of the change. – The paper introduces CAR as an approach to advance the change for sustainability in higher education and discusses some of the implications for universities who are looking to incorporate sustainability as a major part of their culture.

The systematics, biogeography and conservation status of species in the freshwater crayfish genus Engaewa Riek (Decapoda : Parastacidae) from south-western Australia
Publisher: CSIRO Publishing
Date: 2000
DOI: 10.1071/IT99020
Abstract: This paper presents a review of the systematics of freshwater crayfish species in the genus Engaewa Riek, endemic to south-western Australia. Allozyme electrophoresis of six allopatric populations of Engaewa and several outgroup taxa at 17 loci was initially used to identify four distinct genetic groups within the genus. Morphological characters were then used to establish within and between species boundaries more precisely. Five species were recognised, comprising the existing species E. subcoerulea Riek, E. reducta Riek, and E. similis Riek, plus two new species, E. pseudoreducta, sp. nov. and E. walpolea, sp. nov. The genus is endemic to south-western Australia where distributions of species conform to those expected for slowly dispersing, inland aquatic organisms wedded to year-round cool and wet conditions. The range of the genus occurs within the Warren Bioregion of Australia. The species occupy well-defined and largely non-overlapping geographical ranges. Within the bioregion, apparent incipient speciation exists in the Cape Naturaliste–Cape Leeuwin subregion, confirming a pattern observed for other aquatic organisms. Morphological and electrophoretic evidence suggests that species in the genus are more closely related to each other than they are to other species of extant freshwater crayfish, suggesting that they represent a monophyletic group. Nevertheless, the morphological variation displayed by Engaewa clearly falls within that found for the genus Engaeus Erichson from south-eastern Australia, indicating that a broad-scale generic revision for the entire group would be appropriate. The narrow geographical ranges of E. walpolea, sp. nov., E. pseudoreducta, sp. nov. and E. reducta, coupled with known threats to populations, warrant concern for these species from a conservation viewpoint. precisely.
Electrophoretic contributions to the systematics of the freshwater crayfish genus engaeus erichson (Decapoda: Parastacidae)
Publisher: CSIRO Publishing
Date: 1990
DOI: 10.1071/IT9900615
Abstract: As part of an examination into the systematics of the freshwater crayfish genus Engaeus, an electrophoretic evaluation of specimens from a large number of collecting sites has been undertaken. From a total of 76 s le sets, a minimum of 30 distinct biological species have been delineated. Strong evidence from sites of both sympatry and allopatry suggests some further delineations of species but these must await additional discriminatory information. Sympatric species were detected on 11 separate occasions. In each case, fixed allelic differences were found, indicating an absence of interbreeding between each sympatric pair. Allopatric species were delineated where genetic differences between populations exceeded a threshold level determined from observed genetic differences between sympatric Engaeus species and between other (mainly decapod) species in the literature. The results of this analysis have confirmed low levels of heterozygosity in Engaeus species. Frequent isoIation of small populations of Engaeus species, and consequent loss of allelic variation, is suggested as a possible cause of these low levels. Some species have shown variation of allelic frequencies over their geographical range and, in some cases, this variation could be interpreted as showing clinal properties. Finally, the electrophoretic data have been interpreted to produce some information regarding the phylogenetic affinities of delineated species. Several groups of species were found which shared closer intra-group relationships than they did to the other species of Engaeus.
Environmental foundations of typhoid fever in the fijian residential setting
Publisher: MDPI AG
Date: 06-07-2019
Abstract: Proximal characteristics and conditions in the residential setting deserve greater attention for their potential to influence typhoid transmission. Using a case-control design in Central Division, Republic of Fiji, we examined bacterial (coliform and Escherichia coli) contamination and chemical composition of water and soil as potential vehicles of exposure to Salmonella Typhi, combining observational analysis of residential living conditions, geospatial analysis of household locations, and factor analysis to explore multivariate associations with the risk of developing typhoid fever. Factors positively associated with typhoid infection related to drainage [phosphate (OR 4.235, p = 0.042) and E. coli concentrations (OR 2.248, p = 0.029) in toilet drainage soil, housing [external condition (OR 3.712, p 0.001)], drinking water contamination (OR 2.732, p = 0.003) and sanitary condition (OR 1.973, p = 0.031). These five factors explained 42.5% of the cumulative variance and were significant in predicting typhoid infection. Our results support the hypothesis that a combination of spatial and biophysical attributes of the residential setting influence the probability of typhoid transmission in this study, factors associated with poor drainage, flooding, and sanitary condition increase local exposure to contaminated water and soil, and thereby infection. These findings extend testing of causal assumptions beyond the immediate domestic domain, enhance the scope of traditional case control epidemiology and allow greater specificity of interventions at the scale of the residential setting.

Abstract: Policies aiming to preserve vegetated coastal ecosystems (VCE tidal marshes, mangroves and seagrasses) to mitigate greenhouse gas emissions require national assessments of blue carbon resources. Here, we present organic carbon (C) storage in VCE across Australian climate regions and estimate potential annual CO 2 emission benefits of VCE conservation and restoration. Australia contributes 5–11% of the C stored in VCE globally (70–185 Tg C in aboveground biomass, and 1,055–1,540 Tg C in the upper 1 m of soils). Potential CO 2 emissions from current VCE losses are estimated at 2.1–3.1 Tg CO 2 -e yr -1 , increasing annual CO 2 emissions from land use change in Australia by 12–21%. This assessment, the most comprehensive for any nation to-date, demonstrates the potential of conservation and restoration of VCE to underpin national policy development for reducing greenhouse gas emissions.
What happens when you add salt: predicting impacts of secondary salinisation on shallow aquatic ecosystems by using an alternative-states model

Abstract: Alternative-states theory commonly applied, for aquatic systems, to shallow lakes that may be dominated alternately by macrophytes and phytoplankton, under clear-water and enriched conditions, respectively, has been used in this study as a basis to define different states that may occur with changes in wetland salinity. Many wetlands of the south-west of Western Australia are threatened by rapidly increasing levels of salinity as well as greater water depths and permanency of water regime. We identified contrasting aquatic vegetation states that were closely associated with different salinities. Salinisation results in the loss of freshwater species of submerged macrophytes and the dominance of a small number of more salt-tolerant species. With increasing salinity, these systems may undergo further change to microbial mat-dominated systems composed mostly of cyanobacteria and halophilic bacteria. The effect of other environmental influences in mediating switches of vegetation was also examined. Colour and turbidity may play important roles at low to intermediate salinities [concentration of total dissolved solids (TDS) 000 mg L–1] however, coloured or turbid wetlands are rarely found at intermediate to high salinities ( 000 mg L–1 TDS). The role of nutrients remains largely unquantified in saline systems. We propose that alternative-states theory provides the basis of a conceptual framework for predicting impacts on wetlands affected by secondary salinisation. The ability to recognise and predict a change in state with changes in salinity adds a further tool to decision-making processes. A change in state represents a fundamental change in ecosystem function and may be difficult to reverse. This information is also important for the development of restoration strategies. Further work is required to better understand the influence of temporal variation in salinity on vegetation states and probable hysteresis effects.
