The Inside Waters of Vancouver Island Are Critical Foraging Habitat for West Coast Transient Killer Whales

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT West Coast Transient (WCT) killer whales (Orcinus orca rectipinnus) hunt marine mammals along the west coast of North America from California to southeastern Alaska. However, little information is available on their seasonal use of nearshore areas and the relative importance of different parts of their range.

Exploring Progesterone Levels and Scaled Mass Index as Predictors of Pregnancy in Free‐Ranging Belugas

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Monitoring pregnancy rates can provide vital information regarding a population's viability and trajectory. This study combined drone‐based photogrammetry with biopsy darting to determine if the Scaled Mass Index (SMI) estimated from aerial images can be used to identify pregnant, free‐ranging St.

Machine Learning Detection of Scarring Events in Killer Whales

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Detection and analysis of body scars using photo‐identification data of cetaceans can provide insights into life history, behavior, and exposure to threats, but such analyses typically require manual examination of large image datasets. To explore whether machine learning can assist this process, we developed a pipeline for automatically ...

Vulnerability to Global Environmental Change? Isotopic Inference of a Resident Population of Common Bottlenose Dolphins, Tursiops truncatus, in a Coastal Lagoon in the Southern Gulf of Mexico

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Through the isotopic composition of 211 samples of six different tissues (muscle, liver, heart, kidney, spleen, and lung) obtained from 51 Tursiops truncatus strandings over nearly a decade (2013–2022), this study evaluated the impact of environmental variations on a resident population in a coastal lagoon in the southern Gulf of Mexico ...

Adaptive Acoustic Monitoring for Endangered Cook Inlet Beluga Whales in Complex Soundscapes

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Effective conservation of the endangered Cook Inlet beluga whale (Delphinapterus leucas) requires comprehensive spatiotemporal data, yet monitoring efforts remain spatially biased, underrepresenting important southern habitats. Passive acoustic monitoring (PAM) provides the necessary broad‐scale coverage, but its expansion introduces ...
