The vaquita is the most critically endangered marine mammal, with fewer than 19 remaining
in the wild. First described in 1958, the vaquita has been in rapid decline for more than 20 …

The Arctic is warming at an unprecedented rate, with unknown consequences for endemic
fauna. However, Earth has experienced severe climatic oscillations in the past, and …

In many organisms, especially those of conservation concern, traditional lines of evidence
for taxonomic delineation, such as morphological data, are often difficult to obtain. In these …

The deep sea is the largest ecosystem on Earth, yet little is known about the processes
driving patterns of genetic diversity in its inhabitants. Here, we investigated the macro-and …

The recent rise of 'omics and other molecular research technologies alongside improved
techniques for tissue preservation have broadened the scope of marine mammal research …

In oceanic ecosystems, the nature of barriers to gene flow and the processes by which
populations may become isolated are different from the terrestrial environment, and less well …

The harbour porpoise (Phocoena phocoena), a highly mobile cetacean species of the
Northern Hemisphere, inhabits basins that vary broadly in salinity, temperature, and food …

Patterns of genetic structure in highly mobile marine vertebrates may be accompanied by
phenotypic variation. Most studies in marine turtles focused on population genetic structure …

Adults of many free‐ranging delphinid species cannot be reliably sexed at sea. Sexually
mature, known‐sex adult short‐finned pilot, pygmy killer, melon‐headed, and false killer …

Stock assessment approaches are often oversimplified due to lack of biological knowledge
and insufficient data. In spite of world‐wide attention, fishery‐targeted coastal dolphin …
