Abstract Mapping global landings is an important prerequisite for examining causal relationships between fishing and ecological change. Landing statistics, typically provided with poor spatial precision, can be disaggregated into a grid system of cells (30 min ×30 min) using rule‐based approach ancillary data about distributions fished taxa access reporting countries. Presentation time series catch composition then possible many types marine areas including biogeochemical provinces, large...

Abstract: The Australian lungfish, Neoceratodus forsteri, is one of the world’s oldest vertebrate lineages, with a slow life-history and threatened status, requiring immediate conservation efforts. main threats to lungfish populations are degradation availability key macrophyte habitats, water regulation flow modification. As this long-lived species (at least 77 years) has delayed maturity (mature at 10 years), field monitoring alone will not be enough inform challenge ensuring sustainable...
Abstract Most assessments of the effectiveness river restoration are done at small spatial scales (<10 km) over short time frames (less than three years), potentially failing to capture large‐scale mechanisms such as completion life‐history processes, changes system productivity, or lags ecosystem responses. To test hypothesis that populations two species large‐bodied, piscivorous, native fishes would increase in response structural habitat (reintroduction 4,450 pieces coarse woody into a...
Understanding the influence of extrinsic factors such as hydrology and hydraulics on recruitment provides essential insight to inform management fish populations. The critically endangered silver perch Bidyanus bidyanus is a long-lived, potamodromous pelagophil endemic Australia’s Murray–Darling Basin. Declines this species are often attributed river regulation, although quantitative studies linking key aspects its life cycle sparse. We used multidecadal age-structured dataset collected from...
Abstract A growing worldwide body of literature is demonstrating the geomorphic and ecological roles played by wood in rivers. After more than a century removing from rivers many parts world, researchers managers are now interested returning load back to natural condition. The mechanical placement expensive, so it useful know how long will take for in‐stream loads passively recover target recruitment riparian forests. Of fundamental interest alike questions: (1) can river preremoval wood,...
Abstract The construction of dams and weirs, associated changes to hydrological hydraulic ( e.g. , water level velocity) characteristics rivers is a key environmental threat for fish. These multiple stressors potentially can affect fish in variety ways, including by causing their movement, habitat use activity. Understanding how why these occur inform management efforts ameliorate threats. In this context, we used acoustic telemetry examine use, longitudinal movement activity two lowland...
Past waterway management practices worldwide involved extensive removal of instream woody habitat (IWH) and riparian vegetation. The importance for healthy aquatic ecosystems has now been recognised, with approaches reversed to reintroduce replant riverbanks. Knowledge natural or pre-disturbance IWH loads is useful guide such restoration programs; however, datasets are often unavailable. In this study, were mapped along 105km undisturbed rivers in south-eastern Australia. This field dataset...
Abstract Movement is a key driver of the distribution animals and structure populations, communities, ecosystems. Habitat loss fragmentation can compromise movement contribute to population declines. However, there often insufficient knowledge about when, why, where move, particularly in highly modified environments. We present results from an 8‐year study on behavior Murray cod Maccullochella peelii , Australian freshwater fish species that has undergone major declines due part river flow...
Managers and communities are now artificially reintroducing instream woody habitat (IWH) to rivers following historic large-scale removal. Riverscape-scale datasets that quantify existing conditions fundamental setting the priorities allocating resources for such programs. Unfortunately, rare, primarily because assessment approaches limited in their accuracy (remote sensing) or costly labour intensive (field assessments). This study used both field assessments aerial data improve of remotely...
Abstract Removal of instream woody habitat (IWH) is one factor attributed to declines in fish populations worldwide. Restoration IWH help recover now common; however, quantitative predictions about the outcomes these interventions rare. As such, links between and abundance interest managers inform conservation restoration activities. Links attributes, especially IWH, selected species recreational, cultural, ecological significance were explored at 335 sites spanning eight streams across...
Abstract Conservation management of freshwater ecosystems often focuses on mitigating or reversing the negative effects altered patterns river discharge. Assessments interventions frequently focus direct, short‐term responses to discharge without consideration underlying population trends that span multiple years. We sought determine fish populations annual variation in and water temperature after accounting for trends. used data five native one non‐native species, collected over 7–20 years...
Ecological theories often encompass multiple levels of biological organisation, such as genes, individuals, populations, and communities. Despite substantial progress towards ecological theory spanning levels, data rarely are connected in this way. This is unfortunate because different types emerge from the same underlying processes and, therefore, naturally among levels. Here, we present an approach to integrate collected at (e.g., populations) a single statistical analysis. The resulting...
Abstract Reporting uncertainty in environmental measurements and estimates is important for cross‐comparison inter‐comparison of sites other spatial units. One such measure the load large in‐stream wood river systems. In this paper we propose use Weibull distribution to describe central tendency variability loads along a reach. We illustrate link between average or scale parameter distribution. The shape strongly related ability rivers transport rearrange six Victorian test fit distribution,...
Abstract Because of the high costs collecting field data, many species recovery and management plans do not include a monitoring feedback component to measure success interventions refine strategies. Here, we demonstrate how leveraging existing data can provide broad‐scale, cost‐effective information about threatened fish species, Murray Cod Maccullochella peelii , which is cultural recreational importance in Australia. We applied Bayesian hierarchical model abundance catch collected as part...
Outcomes from restoration and reintroduction programs can be enhanced by understanding the habitat use of animals, how likely they are to move why? River blackfish native southeastern Australia where their range abundance have declined. We reintroduced 27 river into two sites, one rehabilitation had been undertaken (with more vegetation, instream woody habitat, undercut banks) an unmanipulated control site. monitored fish for 9 months after release assess site occupancy, use, drivers...
Abstract Freshwater fish are facing an extinction crisis on a global scale, with increasing demand for human water consumption driving the regulation and degradation of freshwater ecosystems. Flow especially poses threat to small‐bodied floodplain creek specialist species through population fragmentation isolation, loss habitats, interactions predators competitors, resulting in reductions species' range abundance. Conserving recovering many will likely require translocation from wild...
