Abstract: Anthropogenic pressures such as river infrastructure, agriculture and power generation are rapidly increasing in Southeast Asia, aimed at providing food security within the region. However, this will lead to unintended river health consequences, and, currently, most Southeast Asian countries have no country-specific tools for monitoring river health. In Myanmar, one of Southeast Asia’s poorest and most rapidly developing countries, no country-specific tools exist, and there is an urgent need to provide tools that can inform better management and trade-off decision making. This research evaluated three rapid macroinvertebrate bioassessment methods under Myanmar conditions. The objective of the research was to assess the applicability of existing internationally accepted indexing methods for use in Myanmar. Through taxa identification in the laboratory and statistical analysis, it was concluded that the method with the best fit for Myanmar taxa is The Asia Foundation index method, although differences were small. This Asia Foundation method is comparable to the Australian Waterwatch method but includes a family present in our s les that is not included in the Waterwatch method. We then modified this method to include Myanmar taxa not recorded in The Asia Foundation method. The modified index method could be further developed into a Myanmar specific tool for widespread use potentially in combination with the also tested miniSASS, a much easier order-based method better suitable for non-professionals. We recommend additional testing using sites on other rivers across the country to establish a professional indexing method for Myanmar.

Abstract: The taxonomic history of the atyid shrimp Paratya in Australia has been one of confusion due to the high morphological variability in material collected from its wide range of distribution. Early research concluded that all material should be considered a single species, P. australiensis Kemp, pending an acceptable revision. After morphological examination of material throughout the known distribution, others concluded that only a single species occurred in Australia. Molecular studies have recognised at least 10 distinct lineages. In the current study, fresh material was collected, and molecular sequencing was undertaken from a single leg from each specimen. Having confirmed the 10 lineages, the specimens were dissected for morphological examination. These lineages are recognised as distinct species and morphological descriptions are provided for seven new species: Paratya walkeri n. sp., P. spinosa n. sp., P. williamsi n. sp., P. whitemae n. sp., P. strathbogiensis n.sp., P. gariwerdensis n. sp. and P. rouxi n. sp. A new combination, P. arrostra Riek, is raised from sub-species to species, P. tasmaniensis Riek is reinstated and P. australiensis Kemp is redescribed. A key based on morphology is included.

Abstract: The wetland communities intimately associated with groundwater sources in the Australian alps are poorly documented compared with the broader (and more obvious) alpine peatlands. In the present work, we report on the vegetation observed immediately around such sources and the characteristics of the supplying groundwater so as to understand the likely factors controlling the observed vegetation assemblage. Thirty-two groundwater sources were identified across three catchments on the Bogong High Plains, Victoria (Australia), and the vegetation associated with these sources surveyed. Groundwater sources occurred across a range of altitudes (1667–1854 m), independent of aspect, and were hydrologically connected to (upstream of) peatlands. Localised mounding adjacent to the groundwater sources resulted in the formation of pools (‘groundwater source pools’). The vegetation within the pools was dominated by bryophytes, with the aquatic bryophyte Blindia robusta the most common species. The groundwater was deficient in major ions, and similar to rainwater apart from elevated concentrations of CO2 accumulated in the groundwater-recharge process. The high CO2 concentrations, combined with the near-constant temperature conditions provided by sustained groundwater flow, are thought to be likely drivers for the high abundance of B. robusta. Although the relative contributions of rain and snow to aquifer recharge are not fully understood for the Australian Alps, these ecosystems are likely to be vulnerable to the changes in precipitation regime that are predicted under climate-change scenarios.

Abstract: We aimed to quantify the delayed effects of flows on aquatic ecosystems using 33 years of monitoring data on macroinvertebrates and water quality and 51 years of hydrological data, spanning 2,300 km of the Murray River, Australia. By incorporating the delayed effects of hydrological indices, along with physicochemical variables, into generalized additive models to form distributed lag nonlinear models for macroinvertebrate richness and abundance, we found that the effects of floods on macroinvertebrates could last up to 32 years, depending on their magnitude. The models indicated that a large flood can cause an initial depression in macroinvertebrate abundance and richness, followed by a sustained increase persisting for over 25 years before returning to preflood levels. Twelve hydrological indices representing the magnitude of flow events were evaluated, with the q90/med (the 6‐monthly flow exceeded 10% of time, ided by the long‐term median) performing (slightly) better than other indices. Competing hypotheses for the mechanisms underlying the apparent long‐term effect of floods were considered, with the most plausible explanation being the flood‐mediated influx of allochthonous organic matter, especially coarse and large woody debris, that might drive the persistent change in the aquatic community. It is generally believed that macroinvertebrate communities recover quickly after floods, but our findings suggest that we may need to reconceptualize the effects that floods can have on aquatic macroinvertebrates and the communities they support, especially in the context of flow restoration and climate change.

Abstract: Rivers and wetlands in Myanmar provide essential services to people in terms of transportation, agriculture, fisheries and a myriad of other ecosystem services, all of which are dependent on a healthy ecosystem. Irrigation channels are also an important part of the infrastructure for daily water use in Myanmar. The objective of this research is to describe the aquatic ecosystem of irrigation channels using aquatic macroinvertebrate communities. The research focused on the taxonomic composition of the aquatic macroinvertebrates of the Zawgyi River and the associated irrigation channels in central Myanmar, east of the city of Mandalay. Significant differences between the river and channels, and among in idual channels, were shown using an analysis of similarity: Bray–Curtis similarity, a multivariate equivalent of the univariate statistical method of analysis of variance: ANOSIM and an analysis of similarity percentages: SIMPER by Plymouth Routines in Multivariate Ecological Research: PRIMER v6 software. The initial findings suggest that there is a clear separation between macroinvertebrate communities at the morpho-species level of identification between river and irrigation channels, while there is less separation between functional feeding groups (FFG) between them. The lower taxonomic level of discrimination at the family level using a water quality index showed no significant difference between river and channels. The preliminary field results indicate that a recently modified biomonitoring index method could be applied in Myanmar to assess the ecological water quality of the modified river, as well as human-made channels.

Abstract: The life histories of the following species were studied over 2 years at various sites throughout the catchment of the La Trobe River: Tasmanocoenis tonnoiri and Tasmanocoenis sp. (Ephemeroptera : Caenidae), Atalophlebioides sp. and two Atalonella spp. (Ephemeroptera : Leptophlebiidae), two Baetis spp. (Ephemeroptera : Baetidae), Leptoperla primitiva and L. neboissi (Plecoptera : Gripopterygidae), Cyphon sp. (Coleoptera : Helodidae), Ecnomus sp. (Trichoptera : Ecnomidae). The life cycles of these species varied from univoltine (four taxa) to bivoltine (Leptophlebiidae, Baetidae, Ecnomus sp.) or trivoltine (T. tonnoiri). Although the species displayed various degrees of synchrony of growth, distinct changes in the size distribution of the larvae or nymphs occurred with time and thus cohorts were evident.

Abstract: Although drought and drying of waters occur globally, the effect of drying on sediment microbial communities underpinning aquatic biogeochemical processes is poorly understood. We used the molecular method of terminal-restriction fragment length polymorphism (T-RFLP) to assess changes in the microbial community structure of sediments undergoing different levels of inundation and drying within a reservoir during drawdown in a drought. Sediments with three hydrological conditions were investigated: dry sediments (no overlying water), littoral sediments (covered with 1–2 mm water) and inundated sediments (covered with m water). S ling was done in winter 2006 (August) and summer 2007 (January) in Lake Hume, Australia. The microbial communities differed significantly between the different levels of inundation at each s ling time. Community structure also changed significantly within each site between winter 2006 and summer 2007, possibly influenced by the change of season or protracted drying. Sites that were ‘littoral’ in winter 2006 became ‘dry’ in summer 2007, and became more similar to communities that were ‘dry’ at both s ling times. This suggested that the hydrological history of specific sites did not heavily influence the response of microbial communities to severe drying, and all communities undergoing ‘dry’ conditions within the summer 2007 s ling responded similarly.

Abstract: Despite the recognised significance of hyphomycetes in the degradation of leaf litter in streams, few studies have been carried out in alpine environments and none in Australian alpine streams. We hypothesised that the fungal communities responsible for leaf decomposition would change over immersion time, and would respond differently at different sites and on different types of vegetation. Leaf bags containing Epacris glacialis (F. Muell.), Eucalyptus pauciflora (Sieber ex. Spreng) and Eucalyptus delegatensis (R.T. Baker) were deployed at different sites in a stream in the Victorian Alpine National Park, south-eastern Australia. Leaf colonisation was delayed for 2 weeks and decay constants for E. pauciflora and E. delegatensis were 0.004–0.005 and 0.006 respectively. Maximum fungal biomass on leaves was similar to that in previous published studies, whereas sporulation rates were two or three orders of magnitude lower, indicating a reduced reproductive effort. Sporulation and DNA-based studies combined showed that fungal communities on the decomposing leaf material changed over time and exhibited significant preferences for leaf type and study site. We have shown that aquatic hyphomycetes can degrade physically tough leaves of Australian alpine plant species, potentially contributing to pathways for particulate carbon to enter alpine-stream food webs.

Abstract: Two species of Caenis with straight forceps with a terminal tuft of spines are described from northern Australia. Male imagoes and nymphs of C. hanleyi n. sp. are described from reared material from the Alligator Rivers Region in the Northern Territory and C. binda n. sp. is described only from male imagoes collected from streams in the Wet Tropics of Queensland. C. hanleyi differs from C. binda by the structure of the forceps with C. binda being longer and narrower with longer apical spines. These are the first records of the genus Caenis in Australia.

Abstract: A new genus, Wundacaenis, is erected for three new species of Australian caenid mayflies. The genus is diagnosed by possession of distinctive lobes on the anterolateral margins of the mesonotum. The distribution of Wundacaenis extends from the Kimberleys in Western Australia, through the Alligator Rivers Region in the Northern Territory, and down the eastern coast to the Shoalhaven River in New South Wales.

Abstract: The current taxonomic understanding of the genus Riekoperla McLellan, 1971 (Gripopterygidae) is poor, with 15 of the 28 species and subspecies having unknown or uncertain larval associations. Sequences of a 657 bp fragment from the mitochondrial gene cytochrome c oxidase subunit 1 (CO1) were obtained from 122 specimens of 13 species collected throughout the alpine areas of New South Wales and Victoria, Australia. Of these, sequence data associated adults and larvae for the following 10 species: R. alpina McLellan, 1971, R. cf. intermedia, R. compressa Theischinger, 1985, R. hynesorum Theischinger, 1985, R. karki McLellan, 1971, R. montana Theischinger, 1985, R. reticulata (Kimmins, 1951), R. rugosa (Kimmins, 1951), R. trapeza Theischinger, 1985, and R. tuberculata McLellan, 1971. Adults of R. intermedia Theischinger, 1985, R. triloba triloba McLellan, 1971 and R. williamsi McLellan, 1971 were sequenced but no larvae were associated with them. The 13 species were reciprocally monophyletic and had minimum interspecific sequence ergences ranging from 7.2–19.5%, higher than the maximum intraspecific sequence ergences (0.6–5.8%). The combination of morphology and molecular data enabled rapid life stage association for alpine Riekoperla species and this method should be used more frequently for other environmentally significant aquatic insects.

Abstract: A new genus, Skolomystax n. gen. is described to include the Australian mayflies previously assigned to the genus Centroptilum (Baetidae). Based on an integrated taxonomic analysis of mitochondrial cytochrome oxidase I and morphology, 12 species are assigned to this new genus, comprising two new combinations, S. elongatus (Suter, 1986) n. comb. and S. collendus (Harker, 1957) n. comb., and ten new species described in the nymphal stage: S. brevis n. sp., S. chionotos n. sp., S. dyarrbi n. sp., S. gippslandicus n. sp., S. goorudensis n. sp., S. hawkingi n. sp., S. leichhardti n. sp., S. paschei n. sp., S. tasmaniensis n. sp., and S. vulgaris n. sp. A species known only from the original description by Harker (1957) is assigned as S. collendus n. comb. the type material is lost, so it is not treated in detail and its validity remains uncertain. Adults of S. elongatus, S. hawkingi n. sp. and S. leichhardti n. sp. are also included. Skolomystax is closely related to Apobaetis, Callibaetis, Callibaetoides and Waltzoyphius, but differs from them in the combination of a wide notch in the labrum with a basal pair of denticles, 3-segmented maxillary palps, hind wing pads present, and single gills without folds. A key to the nymphs of all species of Skolomystax, except S. collendus, is given.

Abstract: The larval taxonomy of Australian stoneflies (Plecoptera) shows a large disparity in knowledge when compared to the adult taxonomy with many species having undescribed larval forms. The importance of stoneflies as an indicator group for monitoring aquatic ecosystems means knowledge of the larval taxonomy and the ability to identify species is essential. This study combined morphology and mitochondrial gene sequences to associate the adult and larval life-stages for species of Dinotoperla Tillyard. Morphological identification of adult males was recognised for 17 of the 35 Dinotoperla species and combining molecular data with morphology confirmed eight new adult-larval life stage associations. Further, molecular data supported the larval taxonomy for five morphospecies which remain unassociated. The combination of molecular and morphological methods enabled the larval morphology to be reassessed for the genus Dinotoperla and this has led to the establishment of two new genera, Odontoperla, gen. nov. and Oedemaperla, gen. nov., and the new species Dinotoperla aryballoi, sp. nov, D. tasmaniensis, sp. nov. and Oedemaperla shackletoni, sp. nov. as well as the new or updated descriptions of the larvae of 31 species and a comprehensive dichotomous key to these larvae.
