Conservation Science and Practice, Volume 7, Issue 4, April 2025.Abstract The “rhinorays” (giant guitarfish‐Glaucostegidae and wedgefish‐Rhinidae) are a critically endangered group of “shark‐like rays,” which have experienced steep global population declines in the past decade due to overfishing. Their slow life histories and high market value increase the risk of trade‐driven extinction and lead to trade‐offs ...

Diversity and Distributions, Volume 31, Issue 4, April 2025.ABSTRACT Aim Climate‐driven extensions of species distributions have serious consequences for human wellbeing and ecosystems. The recent growth of citizen science data collection represents an underutilised resource for the early detection of marine species range extensions (i.e., expansion of species' distributions at the poleward edge) that can ...

Balancing ecotourism and wildlife management through a conservation behavior approach
Conservation Science and Practice, Volume 7, Issue 3, March 2025.We surveyed ecologists, conservationists, and ecotourism professionals to investigate consequences of ecotourism on animal behavior. We highlight four main behavioral themes and solutions for engendering more sustainable ecotourism that mitigates behavioral impacts.

Evaluation of a low-cost, non-invasive survey technique to assess the relative abundance, diversity and behaviour of sharks on Sudanese reefs (Southern Red Sea) [PDF]
, 2014 A low-cost and non-invasive survey technique focused on pelagic sharks was evaluated during an ecotourism cruise on two Sudanese reefs, Angarosh and Sha'ab Rumi, in the Southern Red Sea.

Eocene Shark Teeth From Peninsular Antarctica: Windows to Habitat Use and Paleoceanography
Paleoceanography and Paleoclimatology, Volume 39, Issue 11, November 2024.Abstract Eocene climate cooling, driven by the falling pCO2 and tectonic changes in the Southern Ocean, impacted marine ecosystems. Sharks in high‐latitude oceans, sensitive to these changes, offer insights into both environmental shifts and biological responses, yet few paleoecological studies exist.

Vulnerability of Eastern Tropical Pacific chondrichthyan fish to climate change
Global Change Biology, Volume 30, Issue 7, July 2024.This assessment identifies sharks' vulnerability to climate change in a data‐poor tropical region and suggests management actions. Abstract Climate change is an environmental emergency threatening species and ecosystems globally. Oceans have absorbed about 90% of anthropogenic heat and 20%–30% of the carbon emissions, resulting in ocean warming ...

Environmental factors modulate the distribution of elasmobranchs in southern Mozambique
Frontiers in Marine ScienceInvestigating 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 ...
