Acoustic telemetry provides mortality estimates for threatened river sharks in the Northern Territory, Australia Open
Natural mortality can be used as a measure of a species’ resilience and is widely used in the management of fish species. Natural mortality can be calculated using life history parameters, although this is often not possible for data-poor …

Sex-specific dispersal patterns of the threatened Northern River Shark Open
Quantifying genetic connectivity between populations of a species is important to understand its conservation and management needs. Genetic connectivity implies gene flow among discrete populations occurring via the dispersal of individual…

Influence of hydrological variability and life history strategy on riverine fish assemblages in the Australian wet‐dry tropics Open
Riverine fish assemblages are strongly influenced by attributes of the flow regime. Tropical savannah river systems have distinct and predictable hydrologic seasonality, reflecting the wet‐dry climate, but can vary substantially in terms o…

Reproductive biology of two small-bodied sharks, Carcharhinus coatesi and Rhizoprionodon acutus, in the Northern Territory, Australia Open
Sharks and rays are widely perceived to have slow reproductive rates and, thus, are often considered highly susceptible to population declines from commercial fishing. However, the reproductive biology of sharks is highly diverse, and some…

Monsoonal wet season influences the migration tendency of a catadromous fish (barramundi <i>Lates calcarifer</i>) Open
Many animals exhibit partial migration, which occurs when populations contain coexisting contingents of migratory and resident individuals. This individual‐level variation in migration behaviour may drive differences in growth, age at matu…

Substantial intraspecific trait variation across a hydrological gradient in northern Australian fishes Open
Trait‐based models of ecological communities and ecosystem functioning often fail to account for intraspecific variation in functional traits, assuming that intraspecific variability is negligible compared with interspecific variability. H…

Influence of life history variation and habitat on mercury bioaccumulation in a high-order predatory fish in tropical Australia Open
Mercury distribution and bioaccumulation in aquatic ecosystems of tropical Australia is poorly characterised. Barramundi (Lates calcarifer), a widespread high-order predator in both fresh and coastal marine waters of the region, fulfils re…

Integrated analyses of SNP-genotype and environmental data in a continuously distributed snapper species (<i>Lutjanus johnii</i>, Bloch, 1792) reveals a mosaic of populations and a challenge for sustainable management Open
Understanding population structure is important for predicting the outcomes of anthropogenic development, harvest, and environmental change on the abundance of fisheries species. Logically, the use of several data sources is best for delin…

Faster juvenile growth promotes earlier sex change in a protandrous hermaphrodite (barramundi Lates calcarifer) Open
The relationship between growth and sexual maturation is central to understanding the dynamics of animal populations which exhibit indeterminate growth. In sequential hermaphrodites, which undergo post-maturation sex change, the size and a…

Trait‐based ecology of fishes: A quantitative assessment of literature trends and knowledge gaps using topic modelling Open
Species traits are a new data currency to enhance our understanding of ecological patterns and processes. Trait‐based studies of fishes are numerous in comparison with other animal groups, reflecting the diversity of fish forms and functio…

Comments on Edgar et al. (2018) paper for south‐western Australia Open
Edgar, Ward, and Stuart-Smith (2018) argue that Australian fishery stocks are suffering rapid declines and that to meet sustainability targets an expanded network of ‘no-fishing’ reserves is required. The three lines of evidence used were …

Putting potential environmental risk of Australia's trawl fisheries in landscape perspective: exposure of seabed assemblages to trawling, and inclusion in closures and reserves. FRDC Project No 2016-039 Open
This project implemented the first national spatial approach to quantifying the exposure of mapped seabed assemblages to the footprints of all demersal trawl fisheries that operate on the mainland continental shelf and slope of Australia, …

Muddy waters: An assessment of the suitability of zygocardiac ossicles for direct age estimation in the Giant mud crab <i>Scylla serrata</i> Open
A fundamental characteristic of calcified structures commonly used for direct age estimation in animals is that new material is accreted cumulatively and preserved across ontogeny, thus allowing growth marks to be reliably observed and cou…

Seascape genomics reveals fine‐scale patterns of dispersal for a reef fish along the ecologically divergent coast of Northwestern Australia Open
Understanding the drivers of dispersal among populations is a central topic in marine ecology and fundamental for spatially explicit management of marine resources. The extensive coast of Northwestern Australia provides an emerging frontie…

Strong population structure deduced from genetics, otolith chemistry and parasite abundances explains vulnerability to localized fishery collapse in a large Sciaenid fish, <i>Protonibea diacanthus</i> Open
As pressure on coastal marine resources is increasing globally, the need to quantitatively assess vulnerable fish stocks is crucial in order to avoid the ecological consequences of stock depletions. Species of Sciaenidae (croakers, drums) …
