Lack of Population Structure of an Extreme Migratory Shorebird: Evidence of Gene Flow Between Geographically Disparate Populations. [PDF]

Ecol Evol
Gene flow is key to understand the population connectivity of a given species, specially when small and segregated populations threaten its conservation. In this study we explored the population structure of the Hudsonian Godwit (Limosa haemastica), a long‐distance migratory shorebird.

Aerodynamic Improvements of Buses Inspired by Beluga Whales [PDF]

Journal of Applied Fluid Mechanics, 2023
The innovative bus designs, inspired by the whales, have been developed. The designs are confined to the frontal area of the buses. The new designs are named as the Beluga buses.

“That’s how we know they’re healthy”: the inclusion of traditional ecological knowledge in beluga health monitoring in the Inuvialuit Settlement Region

Arctic Science, 2018
Belugas (Delphinapterus leucas) from the Eastern Beaufort Sea (EBS) population are harvested annually in the Inuvialuit Settlement Region (ISR) during their seasonal migration past coastal communities and harvest camps.

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

Endangered 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.

Serological Detection of Marine Origin Brucella Exposure in Two Alaska Beluga Stocks

Animals, 2022
Among emerging threats to the Arctic is the introduction, spread, or resurgence of disease. Marine brucellosis is an emerging disease concern among free-ranging cetaceans and is less well-studied than terrestrial forms.

Young Belugas Diversify Adult Beluga (Delphinapterus leucas) Behavior

Animal 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 ...
