The effect of foreign compounds on elasmobranchs and the effect of elasmobranchs on foreign compounds

Comparative Biochemistry and Physiology A, Comparative Physiology, 1972
Abstract 1. 1. Foreign compounds generally exert effects on elasmobranchs that are qualitatively similar to those they exert in mammals. 2. 2. Certain drugs acting on higher centers of the central nervous system produce little effect in the dogfish. 3. 3.

The fossil record of extant elasmobranchs

Journal of Fish Biology, 2020
AbstractSharks and their relatives (Elasmobranchii) are highly threatened with extinction due to various anthropogenic pressures. The abundant fossil record of fossil taxa has allowed the tracing of the evolutionary history of modern elasmobranchs to at least 250 MYA; nonetheless, exactly how far back the fossil record of living taxa goes has never ...

Trace elements in edible tissues of elasmobranchs from the North Aegean Sea (Eastern Mediterranean) and potential risks from consumption.

Marine Pollution Bulletin, 2022
Trace elements have the potential to bioaccumulate in marine organisms and to biomagnify towards the upper levels of marine trophic webs, resulting in a range of negative effects on organisms.

Fishermen's participation in research and conservation of coastal elasmobranchs

, 2021
The use of animals from commercial fishing for scientific purposes is a reality in Brazil, emphasizing the importance of a good relationship between researchers and fishermen. To assess the effectiveness of traditional communities’ inclusion in research,

Assessing multiple sources of data to detect illegal fishing, trade and mislabelling of elasmobranchs in Greek markets

, 2020
Elasmobranchs, extremely charismatic and threatened animals, still are an important economic source for fishers in many parts of the world, providing significant income through trade.

Corticosteroids in plasma of elasmobranchs

Comparative Biochemistry and Physiology Part A: Physiology, 1972
Abstract 1. 1. Free corticosteroids were quantified by double isotope derivative assay in thirteen plasma samples from seven species of elasmobranchs. 2. 2. In each instance, four batoids and three selachians, 1α-hydroxycortico-sterone was the principal plasmatic corticosteroid. 3. 3.

Mitigating the discard mortality of non-target, threatened elasmobranchs in bather-protection gillnets

, 2020
Globally, many gillnet fisheries have excessive discards which can comprise charismatic megafauna threatened with extinction, including numerous elasmobranchs. Very few discarded elasmobranch species have been assessed for their associated fates. Here we
