Seasonal water-quality sampling in estuaries, what can it tell us? A case example of eastern Australian subtropical estuaries
Publisher: CSIRO Publishing
Date: 2014
DOI: 10.1071/MF12338
Abstract: Point-s ling of water is often referred to as an inaccurate and crude method for use in estuaries however, budgetary, spatial and time constraints often leave it as the only feasible option. The present paper investigates the relationship between spring water quality and diatom s ling of 52 eastern Australian subtropical estuaries and the OzCoasts determined classification of estuarine condition. In general, estuarine health decreases along the total phosphorus (TP), total nitrogen (TN) and the centric to pennate diatom ratio gradients. However, although there is a general trend, results are varied within each class, with some estuaries classed as extensively modified, recording low nutrient conditions. Principal components analysis (PCA) indicated that 55% of the variance among sites is explained by the first and second axes, with TN, TP, TN : TP, latitude and pH having high correlation with PCA Axis 1, and temperature, conductivity and the centric to pennate diatom ratio being correlated with Axis 2. Two diatom species that may have bioindicator value for estuary conditions were identified. We concluded that even though natural variability and accurate characterisation of estuaries is not possible with point-s ling, it can still identify important information on the status of estuarine condition, particularly in relation to total nutrient concentrations where budget and/or time constraints limit environmental monitoring.

Plasticity of upper thermal limits of Australian Paratya spp. (Decapoda, Atyidae) and considerations of climate-change adaptation
Publisher: CSIRO Publishing
Date: 14-03-2023
DOI: 10.1071/MF22260
Abstract: Context The ability of ectothermic stream invertebrates to adapt to the predicted increases in mean and extreme stream temperatures is crucial to ensuring they continue to exist. Aims To examine the plasticity of thermal limits of Australian Paratya spp. (Decapoda, Atyidae) from streams in eastern New South Wales (NSW). We hypothesised that the upper lethal temperature (ULT, as indicated by the median lethal temperature, LT50) would be higher for warm water-acclimated shrimp in iduals than for winter-acclimatised shrimp in iduals because of the importance of acclimatisation temperature. Methods Controlled experiments were undertaken to determine the ULT by using r ing assays for winter field-acclimatised and warm water laboratory-acclimated Paratya spp. Key results Warm water-acclimated shrimp in iduals demonstrated a significantly higher LT50 of 36.1°C than did winter-acclimatised shrimp in iduals at 34.6°C. Paratya spp. exhibited a limited plasticity for acclimation to warmer temperatures. Conclusions Results demonstrated the potential vulnerability of ectothermic stream invertebrates to climate change if stream temperatures increase as predicted and thermal thresholds are exceeded. Implications Understanding the ULT of stream invertebrates helps predict their ability to respond to temperature variability and response to climate change. Increasing resilience through target management of resorting riparian vegetation for shade and securing environmental flows may reduce the impacts of stream warming.
Identifikasi Service Blueprint di Desa Wisata Kebontunggul (Lembah Mbencirang), Kecamatan Gondang, Kabupaten Mojokerto

DOI: 10.35314/INOVBIZ.V8I2.1549
Abstract: This study aims to comprehend the actual conditions of business processes and to identify service blueprints in the Kebon Tunggul Tourism Village "Lembah Mbencirang" by analyzing their business activities and service flows to visitors. This research is community-based research (CBR) conducted using the Participatory Action Research (PAR) approach. It resulted in the findings that there were various internal problems related to management during 2017-2020, especially related to the accountability and transparency of budget management in addition to more fundamental issues regarding tourist attraction management, such as the absence of an organizational structure, no clear ision of staff duties, and the nonappearance of a standardized service flow. We concluded that basically, the business processes in the Lembah Mbencirang can be grouped into two, the first is the package tour services, and the second is the general visitors’ services. As a tourism product which is essentially a service product, service blueprint is very significant as an effort to understand the service experience from the perspective of the customer, which in this context was not previously owned by the manager. The service blueprint generated from this study can identify the existence of various service processes so that all staff can cognize the context and conditions of their duties in a more holistic customer service perspective.

Establishing ecological reference conditions and tracking post-application effectiveness of lanthanum-saturated bentonite clay (Phoslock®) for reducing phosphorus in aquatic systems: An applied paleol
Publisher: Elsevier BV
Date: 08-2014
DOI: 10.1016/J.JENVMAN.2014.02.038
Abstract: Innovative management strategies for nutrient enrichment of freshwater are important in the face of this increasing global problem, however many strategies are not assessed over long enough time periods to establish effectiveness. Paleolimnological techniques using diatoms as biological indicators were utilized to establish ecological reference conditions, environmental variation, and the effectiveness of lanthanum-saturated bentonite clay (brand name: Phoslock(®)) applied to reduce water column phosphorus (P) concentrations in four waterbodies in Ontario, Canada, and eastern Australia. In sediment cores from the two Canadian sites, there were short-lived changes to diatom assemblages, relative to inferred background conditions, and a temporary reduction in both measured and diatom-inferred total phosphorus (TP) before returning to pre-application conditions (particularly in the urban stormwater management pond which has a high flushing rate and responds rapidly to precipitation and surface run-off). The two Australian sites (a sewage treatment pond and a shallow recreational lake), recorded no reduction in diatom-inferred TP. Based on our pre-application environmental reconstruction, changes to the diatom assemblages and diatom-inferred TP appeared to be driven by larger, climatic factors. While laboratory tests involving this product showed sharp reductions in water column TP, management strategies require detailed information on pre-application environmental conditions and variations in order to accurately assess the effectiveness of new technologies for lake management.

Glacial and Holocene terrestrial temperature variability in subtropical east Australia as inferred from branched GDGT distributions in a sediment core from Lake McKenzie
Publisher: Cambridge University Press (CUP)
Date: 07-2014
DOI: 10.1016/J.YQRES.2014.02.005
Abstract: Branched glycerol dialkyl glycerol tetraether (GDGT) distributions observed in a sediment core from Lake McKenzie were utilized to quantitatively reconstruct the pattern of mean annual air temperature (MAAT) from coastal subtropical eastern Australia between 37 and 18.3 cal ka BP and 14.0 cal ka BP to present. Both the reconstructed trend and litude of MAAT changes from the top of the sediment core were nearly identical to a local instrumental MAAT record from Fraser Island, providing confidence that in this sediment core branched GDGTs could be used to produce a quantitative record of past MAAT. The reconstructed trend of MAAT during 37 to 18.3 cal ka BP and timing of the Last Glacial Maximum (LGM) in the Lake McKenzie record were in agreement with previously published nearby marine climate records. The litude of lower-than-present MAAT during the LGM potentially provides information on the latitude of separation of the Tasman Front from the East Australian current in the subtropical western Pacific. The Lake McKenzie record shows an earlier onset of near modern day warm temperatures in the early Holocene compared to marine records and the presence of a warmer than present day period during the mid-Holocene.

Date: 29-09-2020
Abstract: The new normal phase has already begun. The tourism sector is slowly starting to operate. Setigi (Selo Tirto Giri) is a new tourist destination in the Gresik Regency region that gets priority from the local government to operate. As a new tourist destination, Setigi should have the right development guide. This research was conducted with a qualitative approach for 1 (one) month, where we focused on aspects of qualitative data that refer to the criteria and indicators of tourism destination development. We collect data by field observations, in-depth interviews with key stakeholders, supported by quantitative non-reactive data. The analysis was carried out by the IFAS/EFAS analysis phase, followed by the SWOT/TOWS Matrix analysis technique. This research reveals that, in general, the management of Setigi is in harmony with the principles of the development of tourist destinations and tourist attractions. The manager has also strived to implement the Sapta Pesona criteria into the management of Setigi. However, there are some notes to improve Setigi's performance towards better tourism destinations.
The influence of land use in a highly modified catchment: Investigating the importance of scale in riverine health assessment
Publisher: Elsevier BV
Date: 2018
DOI: 10.1016/J.JENVMAN.2017.12.005
Abstract: Riverine landscapes are studied at varying scales, investigating the complex cause-effect pathways between rivers and their physical, chemical and biological attributes. Policy development, management and planning are often formulated and applied at the regional or catchment scale, however the ecological evidence required to inform at this scale is typically collected from the much smaller scale. This research was aimed at determining if patterns in diatom and macroinvertebrate community composition can be attributed to a specific/single land use in a catchment with multiple land uses. The impacts of forest, macadamia, grazing, sugar cane and urban land uses in the Richmond River Catchment of Northern NSW, Australia were investigated at 20 micro-catchment scale sites. A total of 124 diatom species from 43 genera, along with 92 families and three sub-families of macroinvertebrates, were collected and used to calculate the Richmond River Diatom Index (RRDI), AUSRIVAS and SIGNAL2 scores. Statistical analyses showed distinct groupings of land use categories providing evidence of cause-effect pathways attributed to in idual land uses. The RRDI, AUSRIVAS and SIGNAL2 scores all showed distinctions between land use categories, though they were clearer in the RRDI. The RRDI indicated that the grazing sites had the poorest health of the land use categories, followed by sugar cane and urban while the macadamia and forest sites were relatively healthy. Signal 2 scores showed similar trends to the RRDI, while the AURIVAS scores did not present clear trends, particularly in the edge habitat of macadamia land use sites. The results indicated that riparian vegetation and instream habitat play an important role in attenuating inputs and that rehabilitation efforts could potentially improve water quality at a micro-catchment scale and subsequently, result in river health improvement at the catchment scale. The research collected at this micro-catchment scale presents new evidence that further informs and affects decisions made at the catchment scale, where policy and planning is developed and implemented.

Abstract: This study aims to map tourism potential both in terms of tourism products and markets as an initial step in developing tourism in Ngajum Village. This research is community-based research implemented using the Participatory Action Research approach. The analysis was carried out through 6A's tourism product component approach without disregarding the tourism market analysis. The findings of this study are that Ngajum Village had untapped tourism potentials. Weaknesses in the components of attractions and available packages will be resolved by developing artificial attraction on land A, the potential for ecotourism activities on land B, agro-tourism on people's coffee plantations, spiritual tourism in Padepokan Soerjo Alam, as well as the potential for factory tour collaborations with Greenfield Dairy Factory. These potentials must be designed in stages to obtain optimal outcomes for the community by involving the roles of BUMDES and Pokdarwis as the main actors. In the end, the amenities component is considerably good, while the activities will align with the development of the attraction. The accessibilities and ancillary services are in good condition

Diatoms as indicators of wetland salinity in the Upper South East of South Australia
Publisher: SAGE Publications
Date: 04-2001
DOI: 10.1191/095968301676871383
Abstract: Wetland degradation in the Upper South East of South Australia is an urgent management concern. Scant recent environmental data is available for the region and long-term monitoring data is lacking. Usually a palaeoecological analysis is able to reveal environmental change in the medium-to long-term past. However, the region is not conducive to palaeoecological investigation due to a fluctuating upper groundwater aquifer and alkaline soils whiclh have destroyed most microfossils. It was found that the diatom assemblage was preserved in the wetlands of the region for the period of European settlement. Analysis of the diatom assemblage enabled production of an inferred salinity curve. In combination with a small amount of historical information that was available, the salinity trend for the wetlands, for the period of European agricultural activities, was identified. It was found that, while groundwater salinity has been increasing, the wetland areas have experienced a freshening of surface water. This is due to an increase of throughflow of surface water, a result of constructed drainage systems flushing salts from the wetlands. Despite the freshening of wetlands they continue to degrade due to the changed hydrology, an impact of the drainage structures.

Historic carbon burial spike in an Amazon floodplain lake linked to riparian deforestation near Santarém, Brazil
Publisher: Copernicus GmbH
Date: 22-01-2018
Abstract: Abstract. Forests along the Amazon Basin produce significant quantities of organic material, a portion of which is deposited in floodplain lakes. Deforestation in the watershed may then have potentially important effects on the carbon fluxes. In this study, a sediment core was extracted from an Amazon floodplain lake to examine the relationship between carbon burial and changing land cover and land use. Historical records from the 1930s and satellite data from the 1970s were used to calculate deforestation rates between 1930 to 1970 and 1970 to 2010 in four zones with different distances from the margins of the lake and its tributaries (100, 500, 1000 and 6000 m buffers). A sediment accumulation rate of ∼4 mm yr−1 for the previous ∼120 years was determined from the 240+239Pu signatures and the excess 210Pb method. The carbon burial rates ranged between 85 and 298 gCm-2yr-1, with pulses of high carbon burial in the 1950s, originating from the forest vegetation as indicated by δ13C and δ15N signatures. Our results revealed a potentially important spatial dependence of the organic carbon (OC) burial in Amazon lacustrine sediments in relation to deforestation rates in the catchment. These deforestation rates were more intense in the riparian vegetation (100 m buffer) during the period 1930 to 1970 and the larger open water areas (500, 1000 and 6000 m buffer) during 1970 to 2010. The continued removal of vegetation from the interior of the forest was not related to the peak of OC burial in the lake, but only the riparian deforestation which peaked during the 1950s. Therefore, this supports the conservation priority of riparian forests as an important management practice for Amazon flooded areas. Our findings suggest the importance of abrupt and temporary events in which some of the biomass released by deforestation, especially restricted to areas along open water edges, might reach the depositional environments in the floodplain of the Amazon Basin.

Abstract: The COVID-19 pandemic has plunged the tourism sector. Tourism industries have ceased operations in line with travel restrictions imposed by most countries. With various considerations, the tourism sector must be reopened. Kemenparekraf said ecotourism has the potential to survive in the post-COVID period. East Java with a variety of ecotourism destinations has the potential to become a leading destination. On the other hand, a pandemic caused changes in tourist behavior. Government policies that prioritize ecotourism the advantages of East Java's ecotourism attractions as well as a shift in the tourists' behavior who tend to travel to locations close to home, had an impact on changing tourism patterns in East Java. This research was conducted with a qualitative approach case study to reveal tour patterns in East Java, especially in the cities of Surabaya, Tuban, Batu, Malang City, Malang Regency, and Banyuwangi which contributed to 50% of East Java’s domestic tourist visits. This research was conducted in two phases, where the first stage (literature studies) guides the next phase of qualitative data in the form of interviews with tourism stakeholders. Our findings are that the majority of East Java tourists conduct tours in the regency/city where they live, ecotourism has not become the main choice of domestic tourists, local governments need to further develop potential natural attractions as ecotourism attractions, and existing ecotourism travel patterns are not yet optimized.

240+239Pu depositional signatures as a viable geochronological tool in the Amazon Basin
Publisher: Walter de Gruyter GmbH
Date: 2017
Abstract: Anthropogenic radionuclide signatures associated with nuclear testing are increasingly utilized in environmental science to explore recent sedimentation. In this study, we assess the suitability of Pu radioisotope analysis in floodplain lake environments in the Amazon Basin to form geochronologies during the 20 th century. The 240 Pu + 239 Pu ( 240+239 Pu) signatures in six sediment cores indicate sediment accumulation rates in the floodplain lakes of the major rivers Amazon (2.3 mm year -1 ), Tapajos (10.2 and 2.4 mm year -1 ) and Madeira (3.4, 4.2 and 6.2 mm year -1 ). The results from this study show that 240+239 Pu fallout activities, and the well documented ( 240 Pu/ 239 Pu) atomic ratios of the above ground nuclear tests which began in the 1950’s, are sufficient and well preserved in Amazon floodplain lake sediments to infer chronologies. Lead-210 dating analyses in the same sediment cores produced comparable sediment accumulation rates at three of the six sites. The differences between dating methods may be attributed to the different time scale these dating methods represent and/or in the solubility between Pb and Pu along the sediment column. The geochronologies derived from the 240+239 Pu and 210 Pb dating methods outlined in this work are of interest to identify the effects of changing sediment accumulation rates during the previous century as a result of development, including deforestation, along the Amazon Basin which increased towards the middle of the 20 th century. This study shows that Pu dating provides a viable alternative geochronology tool for recent sediment accumulation (previous ~60 years) along the Amazon Basin.

Mapping foraging habitat for migratory shorebirds in their Australian non-breeding grounds and prioritising sites for conservation and management
Publisher: CSIRO Publishing
Date: 2017
DOI: 10.1071/PC16011
Abstract: Shorebird populations are declining worldwide as a result of the loss of the intertidal habitats upon which they depend. Conservation status is particularly dire for shorebirds on the East Asian–Australasian Flyway. While the flyway transects many international boundaries and involves numerous bilateral conservation agreements, management of remaining habitat at a local scale is imperative to conserving these species. Coastal habitat is affected by multiple anthropogenic stressors, including loss and degradation due to increasing demand for coastal land. In Australia, migration coincides with the summer holiday season when shorebirds are significantly impacted by human disturbance. Managers are frequently required to make trade-offs between wildlife conservation and anthropogenic land uses and when specific quantitative shorebird habitat data and mapping are absent, human interests will naturally take precedence. This paper demonstrates a method for mapping and prioritising management of shorebird non-breeding habitat using an Australian coastal site, the Richmond River estuary. Foraging habitat was surveyed and mapped using GIS with a range of attributes including habitat types, foraging values, disturbance levels and specific foraging distribution of each species. The results highlighted several important foraging areas that were impacted by disturbance and would require intervening management actions to reduce impacts on shorebirds. The GIS data created provide local managers with an effective tool to consider shorebird habitat in the decision-making process. This method could be replicated at other important shorebird habitat sites, leading to enhanced conservation of these declining species.

Waterlogging tolerance of the threatened grass Arthraxon hispidus and implications for its habitat niche within endangered wetlands in north-eastern New South Wales
Publisher: CSIRO Publishing
Date: 2021
DOI: 10.1071/PC20044
Abstract: Knowledge of a target species’ habitat niche and physiological tolerances is important for conservation planning. However, these factors are not well understood for the threatened annual grass Arthraxon hispidus in New South Wales (NSW). Although the species is widespread in modified environments, recent studies have suggested that several threatened wetland types may represent original native habitat for the species, but documented field ex les are lacking and the species’ physiological response to soil moisture is not clear. We undertook a detailed survey of an A. hispidus population within a relatively intact native sedgeland community, and carried out a nursery experiment to test the hydrological tolerances of the species. We found that A. hispidus plants grew more vigorously in poorly drained or waterlogged conditions, suggesting that the species is well-adapted to overcome such stressors, possibly through the formation of adventitious roots, a trait shared by many wetland plants globally. Our field survey confirmed that the A. hispidus population within the study site occurred only within species assemblages that were characteristic of a freshwater wetland formation and that matched descriptions of a listed endangered ecological community. These findings provide a deeper insight into the species’ habitat and threats, and offer a valuable management focus for conservation of A. hispidus as a component of threatened wetland communities in north-eastern NSW.

Publisher: Elsevier BV

DOI: 10.1016/J.JENVMAN.2009.03.001
Abstract: Addressing environmental problems in estuaries is a worldwide problem. Establishing benchmarks and targets for management is critical, whether the aim is conservation, restoration or sustainable use. Palaeoecological techniques have rapidly improved during the past decade, particularly with advances in methods that allow high resolution quantitative assessments of environmental change. Palaeoecology is a useful tool in environmental management as it allows pre-impact conditions, the rate, extent, direction and cause of change, and range of natural variability to be determined. Australian estuarine ecosystems are qualitatively different from the often more well-studied estuaries in North America and Europe, which means site-specific studies of Australian estuaries are needed to inform management. While a potentially useful and valuable tool, palaeoecological techniques have not yet been widely adopted and practically implemented as part of estuarine management strategies and policy frameworks in Australia. We discuss the role palaeoecological techniques have to play in estuarine management by providing two case studies undertaken in Australia that have provided management information. We aim to encourage communication and dialogue between scientists and environmental managers about the potential for widespread practical adoption and implementation of palaeoecological techniques into Australian estuarine science, management and policy frameworks.

Carbon accumulation in Amazonian floodplain lakes: A significant component of Amazon budgets?
Publisher: Wiley
Date: 29-01-2017
DOI: 10.1002/LOL2.10034
Abstract: The Amazon floodplains cover approximately 10% of the Amazon Basin and are composed of predominantly anoxic sediments that may store large amounts of carbon. Our study combines 210 Pb derived sedimentation rates from four recently analyzed sediment cores ( n = 4) with previously published organic carbon (OC) burial estimates ( n = 18) to provide a broad, first order estimate of carbon accumulation in Amazon floodplain lakes. The OC burial rates were 266 ± 57 g C m −2 yr −1 . This rate is several folds greater than those reported for lakes in arctic, boreal, temperate, and tropical regions. The large amount and spatial variation of OC burial rates in these floodplain lakes highlights the need for increased s ling efforts to better measure these potentially important components of the Amazon Basin carbon budget.

The habitat and management of hairy jointgrass (Arthraxon hispidus, Poaceae) on the north coast of New South Wales, Australia
Publisher: CSIRO Publishing
Date: 2020
DOI: 10.1071/PC19017
Abstract: Ecological information about threatened species is required to guide strategic management approaches for effective bio ersity conservation in Australia. Arthraxon hispidus (hairy jointgrass) is a listed threatened species in New South Wales (NSW), but there is limited information on its habitat preferences and native vegetation associations, as well as the impact of historical and ongoing anthropogenic disturbance on its distribution and abundance. In the present study, populations of A. hispidus on the north coast of NSW were surveyed to investigate the habitat characteristics associated with various occurrences of the species. Its preferred habitat was found to be dense ground-cover formations in high-moisture, low-canopy conditions. Cover was highest in moisture-associated assemblages in and around wetlands, drainage lines and groundwater seepages, often in association with native grasses, sedges and herbs. These findings suggest that naturally open freshwater wetland communities comprise the most plausible native habitat niches for A. hispidus populations on the north coast of NSW. A. hispidus also occurs widely among introduced pastures and weeds in previously forested areas, demonstrating the species’ potential to exploit derived habitat. Results indicate that, although ongoing disturbance continues to promote A. hispidus in these exotic-dominated landscapes where historical clearing has created potential habitat opportunities, anthropogenic disturbance (slashing or cattle grazing) is not necessary to sustain A. hispidus within native-dominated wetland communities. Findings suggest more scope for integrated management of A. hispidus within broader native vegetation conservation strategies rather than a single species approach.

Abstract: Despite the great potential of palaeo-environmental information to strengthen natural resource policy, science and practical outcomes naturally occurring archives of palaeo-environmental and ecosystem service information have not been fully recognised or utilised to inform the development of environmental policy. In this paper, we describe how Australian palaeo-environmental science is improving environmental understanding through local studies and regional syntheses that inform us about past conditions, extreme conditions and altered ecosystem states. Australian innovations in ecosystem services research and palaeo-environmental science contribute in five important contexts: discussions about environmental understanding and management objectives, improving access to information, improved knowledge about the dynamics of ecosystem services, increasing understanding of environmental processes and resource availability, and engaging interdisciplinary approaches to manage ecosystem services. Knowledge of the past is an important starting point for setting present and future resource management objectives, anticipating consequences of trade-offs, sharing risk and evaluating and monitoring the ongoing availability of ecosystem services. Palaeo-environmental information helps reframe discussions about desirable futures and collaborative efforts between scientists, planners, managers and communities. However, further steps are needed to translate the ecosystem services concept into ecosystem services policy and tangible management objectives and actions that are useful, feasible and encompass the range of benefits to people from ecosystems. We argue that increased incorporation of palaeo-environmental information into policy and decision-making is needed for evidence-based adaptive management to enhance sustainability of ecosystem functions and reduce long-term risks.

Abstract: Disturbance plays an important role in plant life history strategies and has been documented as both enhancing and threatening populations of the vulnerable grass Arthraxon hispidus (Thunb.) Makino (hairy jointgrass) on the NSW north coast. Mechanical disturbance (slashing) is often used in A. hispidus conservation management, but many Australian plants are adapted to fire-based disturbance regimes. In this study we undertook a field burning experiment, along with soil seed bank s ling and germination trials, to explore how fire influences A. hispidus population dynamics in terms of plant recruitment and seed bank fluctuations. We found that winter burning strongly promoted A. hispidus spring germination without entirely depleting the residual seedbank. Although drought affected our field study population, burning also led to increased adult cover and substantial seed bank replenishment the following autumn. Exposure to a smoke treatment almost doubled the germination rate of A. hispidus seeds in nursery trials. Our study suggests that appropriate burning regimes can help to maintain this species in the landscape, by both structural and chemical mechanisms, by enhancing plant recruitment and facilitating seed bank accumulation. However, some A. hispidus plants also successfully germinated, established, and reproduced in unburnt plots during our study, suggesting that populations of this species can persist without disturbance in some habitats, such as native wetland communities. We found that A. hispidus has a multi-year seed longevity and a persistent seed bank, providing the species a degree of resilience in the event of unpredictable disturbance regimes and climatic anomalies.
