Genetic and Ecological Divergence Between Northwest Atlantic Killer Whale Populations
Ecology and Evolution, Volume 16, Issue 5, May 2026.Killer whale (Orcinus orca) populations exhibit substantial genetic, ecological, and morphological differences across their global distribution. In this study, we use whole‐genome resequencing and compound‐specific stable isotope analysis of amino acids to show concurrent genetic and ecological differentiation in two relatively understudied killer ...

Element concentrations in tissues reveal spatial structure of Atlantic walrus management stocks
The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.Differences in tissue element concentrations confirm geographic differentiation between 2 of Canada's walrus management stocks but reveal additional spatial structure within the largest stock that may have management implications. Abstract Ensuring harvested animal populations are managed at appropriate scales requires an understanding of underlying ...

Measuring Hearing in Wild Beluga Whales [PDF]
, 2016 We measured the hearing abilities of seven wild beluga whales (Delphinapterus leucas) during a collection-and-release experiment in Bristol Bay, AK. Here we summarize the methods and initial data from one animal and discuss the implications of this experiment. Audiograms were collected from 4 to 150 kHz.

Italian National Conference on Sensors, 2022 A key aspect of ocean protection consists in estimating the abundance of marine mammal population density within their habitat, which is usually accomplished using visual inspection and cameras from line-transect ships, small boats, and aircraft. However,
