Open AccessA review of the life history and ecology of euryhaline and estuarine sharks and rays
One-third of all elasmobranchs (sharks and rays) are threatened with extinction. Euryhaline and estuarine generalist elasmobranchs are a group of 29 species that occupy non-marine environments during particula...

Half a century of global decline in oceanic sharks and rays
Overfishing is the primary cause of marine defaunation, yet declines in and increasing extinction risks of individual species are difficult to measure, particularly for the largest predators found in the high ...

Categorising use patterns of non-marine environments by elasmobranchs and a review of their extinction risk
As the state of non-marine aquatic environments (freshwater and estuarine environments with salinities ≤ 30 ppt) continues to decline globally, there is increasing concern for elasmobranchs (sharks and rays) t...

Temporal variation in benthic primary production in streams of the Australian wet–dry tropics
In the Australian wet–dry tropics, seasonal changes in hydrology can influence abiotic conditions and consequently influence standing stocks of benthic biomass and production. While there is some understanding...

Open AccessMitogenomics of the Speartooth Shark challenges ten years of control region sequencing
Mitochondrial DNA markers have long been used to identify population boundaries and are now a standard tool in conservation biology. In elasmobranchs, evolutionary rates of mitochondrial genes are low and vari...
