Evaluating Seasonal vs. Spatial Extrapolation for Cetacean Distribution Models in the California Current

open access: yesMarine Mammal Science, EarlyView.
ABSTRACT Species distribution models (SDMs) have been developed for multiple cetacean species within the California Current Ecosystem (CCE) from shipboard survey data collected by the Southwest Fisheries Science Center (SWFSC) in summer and fall, thus limiting the ability to inform management decisions in cool seasons when abundance and distribution ...

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

open access: yesMarine Mammal Science, EarlyView.
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 ...

Long‐Term Demographic Trends of Near Threatened Coastal Dolphins Living in an Urban Estuary

open access: yesEcology and Evolution
Understanding population demography of threatened species and how they vary in relation to natural and anthropogenic stressors is essential for effective conservation. We used a long‐term photographic capture‐recapture dataset (1993–2020) of Indo‐Pacific

Characterizing Fraser's Dolphin (Lagenodelphis hosei) in the Lesser Antilles: Distribution, Movements, and Co‐Occurrence With Other Cetacean Species to Inform Conservation Strategies in the Caribbean

open access: yesMarine Mammal Science, EarlyView.
ABSTRACT Fraser's dolphin (Lagenodelphis hosei) is one of the least studied dolphin species due to its tropical, offshore distribution and low density. However, it is frequently observed in the Lesser Antilles, where we characterized its distribution and ecology using 4 years of data collected from Grenada to Anguilla.
