On factors for separation of the stock of beluga whale Delphinapterus leucas in the Anadyr Gulf of the Bering Sea

Известия ТИНРО, 2014
New eco-ethological data on the Anadyr stock of beluga whales are presented based on 14-year (2000-2013) studies by methods of satellite tracking telemetry, multi-spectral aerial surveys and genetic analysis, as well as traditional and ecosystem-based ...

Detection and Characterization of New Coronavirus in Bottlenose Dolphin, United States, 2019

Emerging Infectious Diseases, 2020
We characterized novel coronaviruses detected in US bottlenose dolphins (BdCoVs) with diarrhea. These viruses are closely related to the other 2 known cetacean coronaviruses, Hong Kong BdCoV and beluga whale CoV.

A High‐Accuracy TEC Model for Low‐Mid Latitudes Using a BWO‐Optimized CNN‐xLSTM Hybrid Model With Multi‐Instrument Data Fusion

Space Weather, Volume 24, Issue 4, April 2026.
Abstract The total electron content (TEC) in the ionosphere is strongly affected by solar activity and geomagnetic disturbances in mid‐ and low‐latitude regions, making it a major source of error in GNSS navigation and communication systems. To improve the prediction accuracy of ionospheric TEC, this study proposes a deep learning model—Beluga Whale ...

Navigating Cetacean Mitochondrial Genome Data: Identifying Coverage and Deficiencies in Public Repositories

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Genetic reference databases underpin a wide range of molecular approaches used to study cetacean biodiversity, including environmental DNA (eDNA), yet their reliability depends critically on data completeness, taxonomic accuracy, and metadata quality.

Correcting Lipid Extraction Effects on Nitrogen Isotopic Values (δ15N) in Cetacean Skin

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Stable isotopes of carbon (δ13C) and nitrogen (δ15N) are widely used to study the feeding ecology of cetaceans, as they provide critical insights into diet and migratory behaviors. Lipids in tissues may bias the interpretation of δ13C. Because of this, lipids need to be extracted before measuring stable isotope ratios, but their removal may ...

From Participation to Management: Coconstructing Sustainable Practices in the Saint Lawrence Beluga Habitat

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT The Saint Lawrence Beluga population (Delphinapterus leucas), classified as an endangered species since 2014, continues to decline despite various recovery efforts. A growing concern is the impact of recreational boating on this population. Although the stress caused by boat noise and presence is well documented, the regulation and management ...
