A decade of submersible observations revealed temporal trends in elasmobranchs in a remote island of the Eastern Tropical Pacific Ocean [PDF]

Scientific Reports
No-take marine protected areas (MPAs) can mitigate the effects of overfishing, climate change and habitat degradation, which are leading causes of an unprecedented global biodiversity crisis.

An Assessment of Mobile Predator Populations along Shallow and Mesophotic Depth Gradients in the Hawaiian Archipelago. [PDF]

Sci Rep, 2017
Large-bodied coral reef roving predators (sharks, jacks, snappers) are largely considered to be depleted around human population centers. In the Hawaiian Archipelago, supporting evidence is primarily derived from underwater visual censuses in shallow ...

Environmental factors modulate the distribution of elasmobranchs in southern Mozambique [PDF]

Frontiers in Marine Science
Investigating the spatiotemporal ecology of elasmobranchs is an important precursor to their effective management. Understanding long-term patterns in the movement and habitat use of threatened species can improve management plans so that they yield ...

The Phenomenon of Piebaldism in Sharks: A Review of Global Sightings and Patterns. [PDF]

Ecol Evol
Chromatic disorders like piebaldism—a rare form of leucism causing partial pigment loss—have been documented in 25 wild shark cases across 17 species and 11 families, with varying anatomical distribution. This study compiles published and unpublished records to better understand the taxonomic and geographical spread of piebaldism and its potential ...
