Estimating reproductive and juvenile survival rates when offspring ages are uncertain: A novel multievent mark‐resight model with beluga whale case study

open access: yesMethods in Ecology and Evolution, 2023
Understanding the survival and reproductive rates of a population is critical to determining its long‐term dynamics and viability. Mark‐resight models are often used to estimate these demographic rates, but estimation of survival and reproductive rates ...

Hormone profiles from Cook Inlet, Bristol Bay and aquarium beluga whales

open access: yesPolar Research, 2022
Beluga whales (Delphinapterus leucas) from Cook Inlet (CI), Alaska, are listed as “endangered” because of dramatic declines in abundance, with no indications of population recovery. Serum samples from this population are exceedingly rare.

Potential for spatial displacement of Cook Inlet beluga whales by anthropogenic noise in critical habitat

open access: yesEndangered Species Research, 2017
The population of beluga whales in Cook Inlet, Alaska, USA, declined by nearly half in the mid-1990s, primarily from an unsustainable harvest, and was listed as endangered in 2008.

Validation of Growth Layer Group (GLG) depositional rate using daily incremental growth lines in the dentin of beluga (Delphinapterus leucas (Pallas, 1776)) teeth. [PDF]

open access: yesPLoS ONE, 2018
Counts of Growth Layer Groups (GLGs) in the dentin of marine mammal teeth are widely used as indicators of age. In most marine mammals, observations document that GLGs are deposited yearly, but in beluga whales, some studies have supported the view that ...

Young Belugas Diversify Adult Beluga (Delphinapterus leucas) Behavior

open access: yesAnimal Behavior and Cognition, 2015
Across the animal kingdom, immature animals are characterized by their playfulness and diversity of behavior, but are their actions enriching to adult conspecifics? The purpose of this study was to assess if beluga (Delphinapterus leucas) calves influenced the behavioral repertoire of adult conspecifics, specifically with regard to play behaviors ...
