Conservation concerns exist for many sharks but robust estimates of abundance are often
lacking. Improving population status is a performance measure for species under …

Despite international protection of white sharks Carcharodon carcharias, important
conservation parameters such as abundance, population structure and genetic diversity are …

Anthropogenic impacts are believed to be the primary threats to the eastern Australian
population of grey nurse sharks (Carcharias taurus), which is listed as critically endangered …

Many shark species are at risk of overexploitation due to their high economic value, slow
maturation, and low recruitment compared to most teleosts. However, there is insufficient …

Reliable information for population assessments is rare for sharks. We quantified patterns in
catch rates and mean size for numerous tropical and subtropical species from 15 years of …

The loss of apex marine predators has been reported to have a cascade of detrimental
effects on marine ecosystems; however, the general lack of empirical data can severely limit …

The common blacktip shark (Carcharhinus limbatus) and the Australian blacktip shark (C.
tilstoni) are morphologically similar species that co-occur in subtropical and tropical …

South Africa is reputed to host the world's largest remaining population of white sharks, yet
no studies have accurately determined a population estimate based on mark-recapture of …

This study presents genetic evidence that whale sharks, Rhincodon typus, are comprised of
at least two populations that rarely mix and is the first to document a population expansion …

Abstract In Australian and New Zealand waters, current knowledge on white shark
(Carcharodon carcharias) movement ecology is based on individual tracking studies using …
