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.

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 ...
