Fish and coral communities shape elasmobranch reef use in southern Mozambique [PDF]

Scientific Reports
Few studies have explored whether a reef’s bioecological structure affects the presence of elasmobranchs. To examine if the structure of a reef’s fish and coral community influences the likelihood of observing certain elasmobranch species, we deployed a ...

An integrated multi-source dataset of elasmobranchs in the Red Sea following the Red Sea Decade Expedition [PDF]

Scientific Data
Red Sea elasmobranch populations are facing alarming declines. Effective conservation efforts require management strategies informed by extensive datasets and by developing an understanding of distribution patterns within the basin, which is currently ...

Fishers' tales—Impact of artisanal fisheries on threatened sharks and rays in the Bay of Bengal, Bangladesh

Conservation Science and Practice, 2022
Increasing fishing pressure has negatively impacted elasmobranch populations globally. Despite high levels of historical and current fishing pressure, the Bay of Bengal region remains data‐poor.

Elasmobranch microbiomes: emerging patterns and implications for host health and ecology

Animal Microbiome, 2021
Elasmobranchs (sharks, skates and rays) are of broad ecological, economic, and societal value. These globally important fishes are experiencing sharp population declines as a result of human activity in the oceans.

Environmental DNA captures elasmobranch diversity in a temperate marine ecosystem

Environmental DNA, 2022
Many sharks, skates, and rays (elasmobranchs) are highly threatened by the activities of commercial fisheries, and a clear understanding of their distributions, diversity, and abundance can guide protective measures.

Functional diversity of sharks and rays is highly vulnerable and supported by unique species and locations worldwide

Nature Communications, 2023
Elasmobranchs (sharks, rays and skates) are among the most threatened marine vertebrates, yet their global functional diversity remains largely unknown. Here, we use a trait dataset of >1000 species to assess elasmobranch functional diversity and compare

Factors affecting gestation periods in elasmobranch fishes

Biology Open, 2022
Gestation periods vary greatly across elasmobranch species. Differences in body size and body temperature (i.e. major determinants of metabolic rates) might explain such variation.

Lost and found: the posthumous portrait of Louis Agassiz by Henry Ulke (1876), and their noteworthy relationship

Swiss Journal of Palaeontology, 2020
Despite today’s controversy regarding several aspects of his legacy, Swiss-born Harvard Professor Louis Agassiz (1807–1873) was one of the most eminent scientists of his time.

Universal closed-tube barcoding for monitoring the shark and ray trade in megadiverse conservation hotspots

iScience, 2023
Summary: Trade restrictions for endangered elasmobranch species exist to disincentivise their exploitation and curb their declines. However, trade monitoring is challenging due to product variety and the complexity of import/export routes. We investigate
