Beluga (Delphinapterus leucas) granulocytes and monocytes display variable responses to in vitro pressure exposures

Frontiers in Physiology, 2015
While it is widely known that marine mammals possess adaptations which allow them to make repetitive and extended dives to great depths without suffering ill effects seen in humans, the response of marine mammal immune cells to diving is unknown. Renewed

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

Ecology and Evolution, Volume 16, Issue 3, March 2026.
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.

Microbiome‐urothelium crosstalk in bladder cancer: From dysbiosis to clinical translation

iMetaOmics, Volume 3, Issue 1, March 2026.
This review elucidates the critical crosstalk between the urobiome and bladder cancer (BCa), mapping the landscape from ecological dysbiosis to clinical translation. We synthesize emerging evidence on microbial signatures that distinguish BCa patients, exploring key carcinogenic mechanisms including chronic inflammation, genotoxicity, and the gut ...

Size and trends of the bowhead whale, beluga and narwhal stocks wintering off West Greenland

NAMMCO Scientific Publications, 2002
To assess the size and trends of the abundance of the bowhead whale (Balaena mysticetus), the beluga, or white whale (Delphinapterus leucas), and the narwhal (Monodon monoceros) visual aerial surveys were conducted in West Greenland in March 1998 and ...

Foraging ecology of ringed seals (Pusa hispida), beluga whales (Delphinapterus leucas) and narwhals (Monodon monoceros) in the Canadian High Arctic determined by stomach content and stable isotope analysis [PDF]

Polar Research, 2015
Stomach content and stable isotope analysis (δ13C and δ15N from liver and muscle) were used to identify habitat and seasonal prey selection by ringed seals (Pusa hispida; n=21), beluga whales (Delphinapterus leucas; n=13) and narwhals (Monodon monoceros;

A novel system for micron‐scale analysis of energy deposition and response to low‐dose radiation

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Micrometer‐scale evaluation of energy deposition is important for radiation protection and therapy as well as for advancing knowledge of responses to radiation in materials and biological systems. Due to the stochastic nature of radiation interactions, there is significant variation in energy deposition in micrometer‐sized targets ...

Scaled mass index derived from aerial photogrammetry associated with predicted metabolic pathway disruptions in free-ranging St. Lawrence Estuary belugas

Frontiers in Marine Science
The St. Lawrence Estuary (SLE) belugas (Quebec, Canada) are an endangered population whose numbers remain low despite ongoing conservation efforts. Multiple anthropogenic factors and changing environmental conditions are thought to have contributed to ...

Die Arktis bei 2,7 Grad globaler Erwärmung: Schwindende Landschaften

Physik in unserer Zeit, Volume 57, Issue 2, Page 58-65, March 2026.
Eine dicke Eisschicht auf dem Ozean, hunderte Meter tief gefrorener Boden und ein über 3 000 m hoher Eisschild – diese einzigartige Landschaft wird es vermutlich so in Zukunft nicht mehr geben. Eine globale Erwärmung von 2,7 °C, auf die wir aktuell zusteuern, würde die Arktis bis zur Unkenntlichkeit verändern.

Status of the belugas of the St Lawrence estuary, Canada

NAMMCO Scientific Publications, 2002
A population of belugas (Delphinapterus leucas) inhabiting the estuary of the St Lawrence river in Quebec, Canada, was depleted by unregulated hunting, not closed until 1979. Surveys in 1977 showed only a few hundred in the population. Surveys since then
