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 ...

Can denticle morphology help identify southeastern Australian elasmobranchs?

Journal of Fish Biology, Volume 104, Issue 6, Page 1848-1859, June 2024.
Abstract Elasmobranchs are covered in scale‐like structures called dermal denticles, comprising dentine and enameloid. These structures vary across the body of an individual and between species, and are frequently shed and preserved in marine sediments.

Comparative assessment of eDNA metabarcoding and longline deployments for elasmobranch surveying across a large tropical marine park network

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 4, April 2024.
Abstract Medium‐ to large‐scale marine protected areas (MPAs) are playing an increasingly important role in global marine biodiversity conservation. A key question is “how do we collect relevant data on biodiversity and population trends to inform their design and measure success?” This question is particularly relevant for marine taxa that are ...

Environmental factors modulate the distribution of elasmobranchs in southern Mozambique

Frontiers in Marine Science
Investigating 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 ...

Residency of the whitetip reef shark (Triaenodon obesus) in Chatham and Wafer Bays, Isla del Coco National Park, Costa Rica.

, 2020
Introducción: El tiburón punta blanca (Triaenodon obesus) es una especie de arrecife de aguas tropicales, no migratoria, que ha demostrado no tener una alta conectividad costera, como la observada para otras especies de tiburón, sin embargo posee la distribución más amplia de todas las demás especies de tiburón de arrecife del Indo-Pacífico. T. obesus,

Abundance, demography and population structure of the grey reef shark (Carcharhinus amblyrhynchos) and the white tip reef shark (Triaenodon obesus) (Fam. Charcharhinidae)

, 2006
Reef sharks (fam. Carcharhinidae) are high-order predators, found throughout the Indo- Pacific. I examined the abundance, growth, reproduction and demography of two species of reef carcharhinid; the grey reef shark (Carcharhinus amblyrhynchos) and the whitetip reef shark (Triaenodon obesus), and investigated the genetic stock structure of T.
