Abstract Aim After environmental disasters, species with large population losses may need urgent protection to prevent extinction and support recovery. Following the 2019–2020 Australian megafires, we estimated recovery in fire‐affected fauna, inform conservation status assessments management. Location Temperate subtropical Australia. Time period 2019–2030 beyond. Major taxa terrestrial freshwater vertebrates; one invertebrate group. Methods From > 1,050 taxa, selected 173 whose...
Floodplain inundation in rivers is thought to enhance fish recruitment by providing a suitable spawning environment and abundant food habitat for larvae. Although this model has not previously been tested Australian rivers, it often extrapolated fishes of the Murray-Darling Basin. Fortnightly sampling larvae juveniles was conducted unregulated Ovens River floodplain during springsummer 1999 (non-flood year) 2000 (flood year). The only species that increased larval abundance or shortly after...
1. Patterns in abundance and distribution of larval fish a heavily regulated mildly Australian lowland river were compared over four breeding seasons to gain some insight into how regulation affects populations. 2. Larvae from total 13 species nine families recorded the two rivers. The Broken River supported twice as many Campaspe River. rivers shared three introduced but only native species. dominant was not found 3. most abundant classified `opportunists'. They are small, short‐lived...
Abstract Environmental flows aim to mimic components of a river's natural flow variability, including the magnitude, frequency, timing, duration, rate change and predictability events. Aspects regime are thought be linked critical life history strategies many riverine fishes, spawning recruitment. In Murray River, Australia, environmental increasingly being used as restoration tool; however, there is little information about response fish these managed This study reports on results from...
Abstract The modification of river flow regimes poses a significant threat to the world’s freshwater ecosystems. Northern Australia’s resources, particularly dry season flows, are being increasingly modified support human development, potentially threatening aquatic ecosystems and biodiversity, including fish. More information is urgently needed on ecology fishes in this region, their habitat requirements, water policy management ensure future sustainable development. This study used...
Summary Environmental flows are a key restoration technique for conserving ecological function in flow‐degraded rivers. Species‐specific, flow–biota relationships increasingly being used to determine environmental flow needs and manage their use; however, many of these poorly described. We evaluate between variables spawning intensity fish assemblage from the Murray River, Australia, over ten‐year period. developed hierarchical multispecies model that accounted incomplete detection compare...
Blackwater contains high levels of dissolved organic carbon that can be rapidly consumed by microbes, sometimes leading to extremely low oxygen (hypoxia) and drastic consequences for aquatic life, including fish kills. Drought-breaking rains in late 2010 inundated large areas the Barmah–Millewa Forest, southern Murray–Darling Basin, Australia, resulted a prolonged hypoxic blackwater event within forest Murray River downstream. This study investigated short-term effects on crayfish. Compared...
Abstract Human impacts on natural ecosystems are pervasive and will play out more severely as human populations per capita resource use increase. Freshwater critical for well‐being experience a diverse range of human‐induced pressures. Most river systems throughout the world have much‐altered flow regimes. The Murray–Darling Basin in southeastern Australian has been focus an extensive water reform process to address over‐allocation uses. This included many scientific investigations,...
Most fish recruitment models consider only one or a few drivers in isolation, rarely include species’ traits, and have limited relevance to riverine environments. Despite their diversity, fishes share sufficient characteristics that prediction of should be possible. Here we synthesize the essential components hypotheses key features rivers develop model predicts relative strength, for all fishes, under flow conditions. The proposes interactions between physical complexity will create...
A common goal among fisheries science professionals, stakeholders, and rights holders is to ensure the persistence resilience of vibrant fish populations sustainable, equitable in diverse aquatic ecosystems, from small headwater streams offshore pelagic waters. Achieving this requires a complex intersection management, recognition interconnections people, place, that govern these tightly coupled socioecological sociotechnical systems. The World Fisheries Congress (WFC) convenes every four...
The ontogenetic patterns of habitat use by a community fishes in the main channel Broken River, an Australian lowland river, was investigated. Stratified sampling conducted fortnightly across six types throughout spring‐summer period within channel. As predicted ‘low flow recruitment hypothesis’, backwaters and still littoral habitats were important nursery for most species. These found to be used some species all stages their life cycle, while other showed clear shifts preference. Only one...
Abstract Climate change is expected to negatively impact many freshwater environments due reductions in stream‐flow and increases temperature. These conditions, however, can already be found today areas experiencing significant drought; current observations of species' responses droughts used make predictions about their future climate change. Using otolith analysis, we recreated golden perch ( Macquaria ambigua ) growth chronologies from two temperate lake populations southeastern Australia...
Balancing the freshwater needs of humans and ecosystems is a fundamental challenge for management rivers worldwide. River regulation water extraction can affect all components natural flow regime, yet few studies have investigated effects on low-flow end hydrograph. Low-flow periods are hydrologically distinctive ecologically important, varying in nature among climatic zones. Tropical savannah characterized by highly seasonal predictable regimes, but with high interannual variation...

Catastrophic megafires can increase extinction risks; identifying species priorities for management and policy support is critical preparing responding to future fires. However, empirical data on population loss recovery post-fire, especially megafire, are limited taxonomically biased. These gaps could be bridged if species' morphological, behavioural, ecological life history traits indicated their fire responses. Using expert elicitation that estimated changes following the 2019–20...
Two billabongs on the floodplain of Murrumbidgee River, Australia, were partitioned in half with impermeable plastic barriers for four months from summer to winter 1995. The densities carp manipulated establish high- and low-carp biomass treatments each billabong. Final standing stocks billabong 1181 101 kg ha-1 , 669 348 respectively. Turbidity, phytoplankton total dissolved phosphorus concentrations similar both ends before establishment barriers. Throughout experimental period, turbidity...
River regulation can have various effects on the natural flow regime, however most obvious and perhaps pronounced hydrological effect is reduction of total water discharge. Whilst there has been an increasing number studies investigating impacts river lowland rivers, few specifically investigated extractions small upland streams. In this study, we experimentally examined short-term, summer from small, unregulated Five 30 m reaches were manipulated to divert a proportion stream flow, another...
Abstract Species traits are a new data currency to enhance our understanding of ecological patterns and processes. Trait‐based studies fishes numerous in comparison with other animal groups, reflecting the diversity fish forms functions they provide aquatic ecosystems. We conduct retrospective examination literature identify knowledge gaps guidance for future research trait‐based ecology. apply an automated text mining topic modelling track evolution topics within peer‐reviewed articles...
