Many exploited fish and macroinvertebrates that utilize the coastal zone have declined, and
the causes of these declines, apart from overfishing, remain largely unresolved. Degradation …

Many populations of elasmobranchs (sharks and rays) are experiencing severe declines
due to the high demand for shark fins in Asia, the activities of unregulated fisheries, and …

Sharks exhibit peculiar characteristics, which may lead to overfishing to cause irreversible
damage to stocks and failing to restore original population sizes. Although global fin trade …

The population structure of the highly mobile marine mammal, the harbor porpoise
(Phocoena phocoena), in the Atlantic shelf waters follows a pattern of significant isolation-by …

Dispersal in many organisms is asymmetric by sex, a pattern that is often identified through
the use of genetic tools. Sex-biased dispersal (SBD) is thought to derive from the varying …

The current shift of fishery efforts towards the deep sea is raising concern about the
vulnerability of deep-water sharks, which are often poorly studied and characterized by …

Abstract Knowledge of the mechanisms limiting connectivity and gene flow in deep‐sea
ecosystems is scarce, especially for deep‐sea sharks. The Portuguese dogfish (C …

Elasmobranchs are a vulnerable resource, more susceptible to overfishing than most
teleosts, and their assessment is complicated due to a general lack of information about their …

The gulper sharks (genus Centrophorus) are a group of deep-water benthopelagic sharks
