Blacktip reef sharks (Carcharhinus melanopterus) show high capacity for wound healing and recovery following injury [PDF]

Conservation Physiology, 2015
Wound healing is important for sharks from the earliest life stages, for example, as the 'umbilical scar' in viviparous species heals, and throughout adulthood, when sharks can incur a range of external injuries from natural and anthropogenic sources. Despite anecdotal accounts of rapid healing in elasmobranchs, data regarding recovery and survival of ...

Drone-Based High-Resolution Tracking of Aquatic Vertebrates

Drones, 2018
Determining the small-scale movement patterns of marine vertebrates usually requires invasive active acoustic tagging or in-water monitoring, with the inherent behavioural impacts of those techniques.

Examining the efficacy of a sanctuary to protect sharks in the Galapagos Marine Reserve

Conservation Science and Practice, Volume 8, Issue 8, August 2026.
Abstract In 2016, Ecuador established a no‐take marine sanctuary in the northern portion of the Galapagos Marine Reserve (GMR), ostensibly to protect sharks. Arguably because of this, experimental longlining was permitted in the rest of the reserve as part of a compensation package to local fishers. Considering this agreement and very low bycatch rates

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 ...

Simulated ocean acidification affects shark tooth morphology

Frontiers in Marine Science
Changing ecological factors pose a challenge to many organisms. Global changes and the associated environmental changes have major impacts on marine organisms and threaten the biodiversity of marine ecosystems.

Assessing Risk for Bycatch and Byproduct Species Using a Modified Sustainability Assessment for Fishing Effects (SAFE) Approach

Fish and Fisheries, Volume 27, Issue 4, Page 831-849, July 2026.
ABSTRACT Central to ecosystem‐based fisheries management is ensuring the sustainability of bycatch and byproduct species. However, the sustainability of these species is difficult to assess as the lack of information limits the use of traditional stock assessment methods.

Genetic Diversity and Population Structure of Squalus cf. mitsukurii (Chondrichthyes: Squalidae) Revealed by ddRAD Sequencing

Animal Genetics, Volume 57, Issue 2, April 2026.
ABSTRACT Assessing genetic structure across ocean basins is essential to understand connectivity and guide conservation in data‐deficient open‐water sharks. In this study, we examined the population genomics of Squalus cf. mitsukurii by analyzing tissue samples collected from two distant regions: California, USA (Pacific Ocean) and Pernambuco, Brazil ...

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
