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 ...

Spatial and temporal analysis of juvenile blacktip reef shark (Carcharhinus melanopterus) demographies identifies critical habitats

Journal of Fish Biology, 2023
AbstractReef shark species have undergone sharp declines in recent decades, as they inhabit coastal areas, making them an easy target in fisheries (i.e., sharks are exploited globally for their fins, meat, and liver oil) and exposing them to other threats (e.g., being part of by‐catch, pollution, and climate change). Reef sharks play a critical role in

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

Anthropogenic disturbance modifies spatial patterns of reef sharks

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Species‐specific sensitivities mean that non‐extractive human presence can strongly reshape reef predator distributions even where fishing pressure is limited. Integrating tourism intensity and coastal development into marine spatial planning is therefore essential for reef shark conservation, and combining ecological surveys with open‐source social ...

Ecological insights to inform management of shark catches in Muncar, Indonesia

Oryx
Shark populations face global declines, primarily as a result of overfishing. These declines threaten marine ecosystems and require urgent conservation attention.

The Overlooked Threat of Global Warming on Elasmobranch Fertility

Fish and Fisheries, Volume 27, Issue 1, Page 41-55, January 2026.
ABSTRACT Climate change is increasingly recognised as a critical threat to global biodiversity, yet its impacts on reproductive processes remain poorly understood in many marine taxa. Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes.

“This research is important for the conservation and Management of Sharks”: A proposed framework for ensuring that this is actually true

Conservation Science and Practice, Volume 7, Issue 12, December 2025.
Many scientists want their research to inform policy and help manage endangered species, but many common research practices hinder potential policy relevance. The results of our survey provide advice that can help. Abstract Sharks and their relatives are ecologically important animals that face serious conservation challenges.

Spatiotemporal patterns and habitat associations of blacktip reef shark in a shallow tropical bay

Environmental Biology of Fishes
Abstract Despite being a common reef shark species, the distribution and habitat use of blacktip reef sharks ( Carcharhinus melanopterus ) remain poorly understood within Malaysia’s marine parks.

Integrating Environmental DNA Metabarcoding and Remote Sensing Reveals Known and Novel Fish Diversity Hotspots in a World Heritage Area

Diversity and Distributions, Volume 31, Issue 11, November 2025.
ABSTRACT Aim Shark Bay, a UNESCO World Heritage site in Western Australia, is highly vulnerable to climate change, yet its fish biodiversity remains poorly understood at fine spatial scales. We integrated environmental DNA (eDNA) metabarcoding with high‐resolution remote sensing to assess and extrapolate fish diversity patterns, providing a scalable ...

DNA Divers: Volunteer‐based eDNA capture for local and global marine biodiversity monitoring

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2431-2447, October 2025.
Abstract Volunteer‐based biodiversity recording is a powerful source of scalable data yet to be used to its full potential by the scientific community. Coastal ecosystems are varied and diverse, making it difficult for managers to identify flexible methods for monitoring biological components.
