The Record of the Last Sturgeons Caught in the Po River (North Italy) Tells a Cautionary Tale of Reasons of Their Silent Disappearance

River Research and Applications, Volume 42, Issue 1, Page 277-283, January 2026.
ABSTRACT Three sturgeon species—the common European (A. sturio), beluga (H. huso), and Adriatic sturgeon (A. naccarii)—coexisted in the Po River Basin until the mid‐1970s, representing centuries of bio‐cultural heritage for northern Italy's riverine communities.

Talking About the Weather: The Feasibility of Using Very High‐Resolution Optical Satellite Imagery to Monitor Live and Stranded Cetaceans Around the UK and UK Overseas Territories

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Monitoring live and stranded cetaceans can be expensive and logistically challenging, resulting in knowledge gaps. Very high‐resolution (VHR) optical satellites are considered a potential solution to addressing some of these gaps. Despite success at detecting live and stranded cetaceans, satellites have only been trialed on restricted ...

A Detailed Characterization of the Whistle Repertoire of Fraser's Dolphins (Lagenodelphis hosei) From the Lesser Antilles

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Fraser's dolphin (Lagenodelphis hosei) remains poorly studied due to its elusive behavior, rarity, and preference for deep offshore habitats. While dolphins use frequency‐modulated whistles for communication, detailed acoustic descriptions exist for only a few species.

Estimating Narwhal (Monodon monoceros) Age Using Epigenetic Analysis of Skin

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Age is an important parameter to understand species life‐history characteristics. Recently, DNA methylation methods have emerged as innovative tools to estimate the age of marine mammals. Narwhal (Monodon monoceros) epigenetic age estimates were computed using beluga (Delphinapterus leucas), killer whale (Orcinus orca), bowhead (Balaena ...

Scouting with drones to increase efficiency of locating wild pigs for removal

Wildlife Society Bulletin, Volume 49, Issue 4, December 2025.
Our goal was to determine if locating wild pigs with thermal cameras mounted on unmanned aerial vehicle technology, drones, just prior to ground and aerial shooting efforts could increase removal rates of invasive wild pigs. Results suggest that scouting with drones can increase removal rates under a variety of conditions. Abstract Effective management

Spermatological parameters of wild and cultured beluga (Huso huso Linnaeus, 1758) and their effects on fertilization rate, hatching rate, larval growth and survival rates

Caspian Journal of Environmental Sciences, 2016
To compare the reproductive performance of the wild and cultured stocks of beluga, Huso huso males, some spermatological parameters were measured including: sperm motility, sperm density, spermatocrit and also fertilization rate, hatching rate and ...

Comparison of fatty acids biochemical quality in the caviar of reared and wild beluga, Huso huso [PDF]

تغذیه آبزیان, 2017
In this study, the quality of fatty acids in sturgeon caviar were assessed and compared in rearedand wild specimens of beluga, Huso huso caught from the Caspian Sea. The fatty acids profile, n3/n6 and atherogenic and thrombogenic index were also measured.

Use of satellite imagery to estimate distribution and abundance of Cumberland Sound beluga whales reveals frequent use of a glacial river estuary

Frontiers in Marine Science
Limiting disturbance in critical habitats is an important part of ensuring the well-being and sustainability of populations at risk, such as Cumberland Sound beluga whales (Delphinapterus leucas). Using non-disruptive Very High Resolution (VHR) satellite
