Larger and more abundant legal-sized targeted fish inside ‘no take’ areas of a subtropical marine park over a 12-year period

Context Multiple-use marine parks vary spatially in how they are managed, which may influence ecological response over time. Aims We surveyed four key targeted species (snapper, Chrysophrys auratus; pearl perch, Glaucosoma scapulare; venus tuskfish, Choerodon venustus; grey morwo...

Development of the drought and supplementary feed calculator (DASFC) phone application

Context Grazing cattle and sheep regularly suffer from feed shortfalls, which can be addressed by supplementary or drought feeding. Tools such as GrazFeed are often used in these circumstances. However, their use is mainly by consultants because they can be complex and time-consu...

Search for sociality in white sharks: investigation of the co-occurrence of juvenile white sharks (Carcharodon carcharias) using passive acoustic telemetry data

Context Social network analysis (SNA) as a quantitative measure of animal grouping and social behaviours has been increasingly used to study the group dynamics and potential sociality of elasmobranch species. Aims Despite their mainly solitary swimming and hunting behaviours, whi...

Spatial heterogeneity in exposure to Brucella suis and pathogenic leptospires in feral pigs across New South Wales

Feral pigs (Sus scrofa) are important reservoirs for zoonotic and livestock pathogens in Australia, but robust information on the spatial distribution of pathogens in pig populations remains limited. We analysed serological data from a systematic, state-wide surveillance program...

A CRISPR‐Based Rapid Detection Assay for Crayfish Plague ( Aphanomyces astaci ) From Environmental Samples

Crayfish plague, caused by Aphanomyces astaci (Aa), is an infectious disease invasive in Europe, where its rapid spread has resulted in sharp declines of native crayfish species. Monitoring currently relies on a highly sensitive, but costly and time-consuming qPCR approach. Here,...

Environmental conditions shape the movement patterns of a marine ambush predator on homogeneous soft sediment habitat

Abstract Background Quantifying the patterns and drivers of animal movement is critical to the effective conservation and management of species across all ecosystems. Despite their importance for global commercial and recreational fisheries, the movement patterns of marine soft s...

Integrated crop residue return, film mulching, and irrigation enhance climate resilience of maize production and soil carbon storage in cold regions

Climate change is expected to intensify changes in soil freeze–thaw processes, thereby affecting water availability and agricultural productivity. However, the mechanistic links among climate-induced changes in seasonal freeze–thaw conditions, maize productivity, and soil organic...

Two major floods affect fish, invertebrates and marine habitats within a temperate estuary

Context Severe flooding can cause physiological stress and mortality for marine organisms within estuaries through reduced salinity, increased turbidity and sedimentation, and the delivery of nutrients, organic matter and contaminants. Aims The Port Stephens estuary in Australia...
