As biodiversity continues to decline across the globe, conservation of wildlife species and
the ecosystems they inhabit is more important than ever. When species dwindle, ecosystems …

Although tool use may enhance resource utilization, its fitness benefits are difficult to
measure. By examining longitudinal data from 196 radio-tagged southern sea otters …

Recovery of wildlife and their ecosystems may require enhancement of vulnerable
populations through human intervention. As a southern sea otter (Enhydra lutris nereis) …

Allometric analyses of sexually selected structures have revealed many patterns of
evolutionary and behavioural significance, for example, in weapons, ornaments, and …

Southern sea otters (Enhydra lutris nereis) are currently> 80% depleted with respect to both
abundance and range occupancy baselines, challenging the long-term persistence of the …

The development of epigenetic clocks, or the DNA methylation‐based inference of age, is an
emerging tool for ageing in free ranging populations. In this study, we developed epigenetic …

Most studies which deal with natural populations require a reliable and convenient way of
age estimation. However, even rough aging of live individuals is often a real challenge. In …

As part of routine captive management of the species, sea otter (Enhydra lutris) males are
often castrated to prevent reproduction, to preserve limited spaces for future nonreleasable …

Sea otters were extirpated throughout much of their range by the maritime fur trade in the
18th and 19th centuries, including the coast of Katmai National Park and Preserve in …

During the evolution of most marine mammals, fur as an insulator has been replaced with
more buoyant, energy storing and streamlining blubber. By contrast, the sea otter (Enhydra …
