Variable post-release mortality in common shark species captured in Texas shore-based recreational fisheries

PLoS ONE, 2023
The practice of catch and release fishing is common among anglers but has been shown to cause unintended mortalities in some species. Current post-release mortality estimates used in coastal shark stock assessments are typically derived from boat-based ...

Volitional Swimming Kinematics of Blacktip Sharks, Carcharhinus limbatus, in the Wild

Drones, 2020
Recent work showed that two species of hammerhead sharks operated as a double oscillating system, where frequency and amplitude differed in the anterior and posterior parts of the body. We hypothesized that a double oscillating system would be present in

Ecological drivers of shark distributions along a tropical coastline.

PLoS ONE, 2015
As coastal species experience increasing anthropogenic pressures there is a growing need to characterise the ecological drivers of their abundance and habitat use, and understand how they may respond to changes in their environment.

Predictions of southern migration timing in coastal sharks under future ocean warming. [PDF]

Conserv Biol
Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from

Delineation and mapping of coastal shark habitat within a shallow lagoonal estuary.

PLoS ONE, 2018
Estuaries function as important nursery and foraging habitats for many coastal species, including highly migratory sharks. Pamlico Sound, North Carolina, is one of the largest estuaries in the continental United States and provides a variety of potential
