Genetic Diversity and Population Structure of the Pelagic Thresher Shark (Alopias pelagicus) in the Pacific Ocean: Evidence for Two Evolutionarily Significant Units [PDF]
PLoS ONE, 2014 There has been an increasing concern about shark overexploitation in the last decade, especially for open ocean shark species, where there is a paucity of data about their life histories and population dynamics.

Conservation Science and Practice, 2022 The pelagic thresher shark is among the most heavily exploited shark species in the commercial fisheries of the tropical Indo‐Pacific oceans. Despite this severe exploitation, little is known about pelagic thresher population dynamics, particularly the ...

Vertical movements of a pelagic thresher shark (Alopias pelagicus): insights into the species’ physiological limitations and trophic ecology in the Red Sea [PDF]
Endangered Species Research, 2020 The pelagic thresher shark Alopias pelagicus is an understudied elasmobranch harvested in commercial fisheries of the tropical Indo-Pacific. The species is endangered, overexploited throughout much of its range, and has a decreasing population trend ...

Beyond the Meal: Trophic Controls by Pelagic and Demersal Chondrichthyes in Two Different Mediterranean Marine Food Webs. [PDF]
Ecol EvolPelagic and demersal sharks played different top‐down controls in the food web. Pelagic sharks act as apex predators impacting mesoconsumers. Trophic controls patterns by demersal sharks change according to ecosystem traits. ABSTRACT Pelagic and demersal Chondrichthyes can assume different patterns of trophic controls on marine food webs, sustaining ...

Chemosphere, 2022 To quantify maternal provisioning of nutrients in the pelagic thresher shark (Alopias pelagicus) and the potential for negative impacts, the concentrations of trace elements (essential: Co, Cr, Cu, Mn, Ni, Se, and Zn; nonessential: As, Ba, Cd, Hg, and Pb) and fractionation of stable isotopes (13C and 15N) were analyzed in the muscle and liver of 10 ...

Journal of Morphology, 2020 AbstractShark skin denticles (scales) are diverse in morphology both among species and across the body of single individuals, although the function of this diversity is poorly understood. The extremely elongate and highly flexible tail of thresher sharks provides an opportunity to characterize gradients in denticle surface characteristics along the ...

Genetic identification of three CITES-listed sharks using a paper-based Lab-on-a-Chip (LOC). [PDF]
PLoS ONEThreatened shark species are caught in large numbers by artisanal and commercial fisheries and traded globally. Monitoring both which shark species are caught and sold in fisheries, and the export of CITES-restricted products, are essential in reducing ...
