Semi‐Automated Detection of Right Whales (Eubalaena spp.) in Very High‐Resolution Satellite Imagery

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT Space‐based detection of whales is proliferating because it shows promise as a monitoring tool, yet tests of its application across taxa and environments are rare. The objective of this study was to develop an end‐to‐end, semi‐automated procedure for detecting two right whale species ( Eubalaena glacialis and E.

Investigating Harvest and Vessel Traffic Exposure as Drivers of Social Group Characteristics in Canadian Beluga ( Delphinapterus leucas ) Populations

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT Assessing variation in social behaviors of group‐living animals may provide insight into the impacts of population stressors. Using very high resolution (VHR) satellite imagery acquired over 3 years, we compared social group size and composition, as well as spatial and social cohesion in three beluga ( Delphinapterus leucas ) populations that ...

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps)

The Anatomical Record, Volume 308, Issue 9, Page 2413-2432, September 2025.
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland
