Thermal reference points as an index for monitoring body temperature in marine mammals [PDF]
, 2015 BACKGROUND Monitoring body temperature is essential in veterinary care as minor variations may indicate dysfunction. Rectal temperature is widely used as a proxy for body temperature, but measuring it requires special equipment, training or ...

Intraspecific variation of cochlear morphology in bowhead and beluga whales
The Anatomical Record, Volume 309, Issue 6, Page 1514-1529, June 2026.Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

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 ...

Development of Beluga, Delphinapterus leucas, Capture and Satellite Tagging Protocol in Cook Inlet, Alaska [PDF]
, 2000 Attempts to capture and place satellite tags on belugas, Delphinapterus leucas, in Cook Inlet, Alaska were conducted during late spring and summer of 1995, 1997, and 1999. In 1995, capture attempts using a hoop net proved impractical in Cook Inlet.

Ecology and Evolution, Volume 16, Issue 5, May 2026.We compared the traditional two‐dimensional (2D: δ13C and δ15N) isotopic niches with a three‐dimensional (3D: δ13C, δ15N, and δ34S) framework to evaluate changes in niche size and overlap. Overall, invertebrates and benthic‐associated species showed greater changes in niche size and reduced overlap using the 3D approach.

First molecular determination of herpesvirus from two mysticete species stranded in the Mediterranean Sea [PDF]
, 2015 BACKGROUND Herpesvirus can infect a wide range of animal species: mammals, birds, reptiles, fish, amphibians and bivalves. In marine mammals, several alpha- and gammaherpesvirus have been identified in some cetaceans and pinnipeds species.

BARTONELLA HENSELAE IN CAPTIVE AND HUNTER-HARVESTED BELUGA (DELPHINAPTERUS LEUCAS) [PDF]
Journal of Wildlife Diseases, 2008 Previously, we reported the isolation of Bartonella henselae from the blood of harbor porpoises (Phocoena phocoena) and loggerhead sea turtles (Caretta caretta) from the North Carolina coast. Hematologic, pathologic, and microbiologic findings surrounding the death of a juvenile captive beluga in Vancouver initiated an outbreak investigation designed ...
