How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Connecting post-release mortality to the physiological stress response of large coastal sharks in a commercial longline fishery.

PLoS ONE, 2021
Bycatch mortality is a major factor contributing to shark population declines. Post-release mortality (PRM) is particularly difficult to quantify, limiting the accuracy of stock assessments.

Global Patterns and Drivers of Climate Vulnerability in Sharks and Rays: A Reassessment Using the IRACC Framework

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT Climate vulnerability in sharks and rays is unevenly distributed across habitats and ecological groups, reflecting differences in exposure pathways and biological constraints. Using an updated application of the Integrated Risk Assessment for Climate Change (IRACC) framework, we conducted a global reassessment of climate vulnerability for 95 ...

Identification of Shark Fin Using 12S rRNA Gene Marker(利用12S rRNA基因标记鉴定鱼翅真伪) [PDF]

Shipin kexue jishu xuebao, 2017
To detect authenticity and species of 23 suspected shark fin samples. DNAs from either shark fin or shark fin derived soup were extracted, and then 12S rRNA gene of mitochondrial DNA that was special for animal species identification was amplified.

Tracking Fin‐Prints on Reef Flats: A Genus‐Specific eDNA Metabarcoding Assay for Epaulette Sharks (Hemiscyllium spp.) With Field Validation in Raja Ampat

Environmental DNA, Volume 8, Issue 3, May–June 2026.
This study developed and validated the first genus‐specific eDNA assay for epaulette sharks (Hemiscyllium spp.), targeting the NADH4 gene. Field application in Raja Ampat detected H. freycineti at six of seven locations, including one location (Dayan) where daytime visual surveys failed, demonstrating this tool's value for monitoring protected species.

Diversity, Abundance and Distribution of Sharks in a Multispecies Nursery Area in the Eastern Central Atlantic

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 4, April 2026.
ABSTRACT Shark nursery habitats are priority targets for area‐based conservation as they protect key age classes that exhibit restricted area use. However, the lack of detailed, species‐specific biological and ecological data often undermines the efficacy of coastal management strategies. This study employed complementary Baited Remote Underwater Video
