Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Alphaherpesvirus: isolation, identification, partial characterisation, associated pathologic findings, and epidemiology in beluga whales (Delphinapterus leucas) in Alaska and Arctic Canada

Arctic Science, 2018
Live, dead stranded, and harvested belugas (Delphinapterus leucas) in Alaska and the western Canadian Arctic were screened for viruses utilizing a primary beluga cell line. Samples consisted of swabs from blowhole, anus, and genital tract.

Diverging Food Web Functioning Around Southampton Island, Nunavut: The Influence of Primary Production Supply and Bathymetry

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Southampton Island hosts two distinct benthic sub‐webs, north and south. North is deeper, phytoplankton‐driven; South is shallower, more ice‐algae driven. North benthos: bottom‐up control, four trophic levels including apex predators. South benthos: walrus top‐down control, trophic truncation to three levels.

An epigenetic clock to estimate the age of living beluga whales

bioRxiv, 2020
Introduction DNA methylation data facilitate the development of accurate molecular estimators of chronological age, or ‘epigenetic clocks.’ We present a robust epigenetic clock for the beluga whale, Delphinapterus leucas, developed for an endangered ...

Inundation Duration Shapes Germination of Native and Non‐Native Plant Assemblages From Floodplain Soil Seedbanks

Ecohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Episodic inundation regulates germination and recruitment from soil seedbanks, which are key processes driving vegetation dynamics in dryland floodplains. In the Murray‐Darling Basin, extensive floodplain modification and flow regulation have altered flow regimes so that anthropogenically controlled environmental watering is often required to ...

Dependence Between Effort Offsets and Process Intensity in Generalized Models for Count Data: Spatial Models of Animal Abundance

Environmetrics, Volume 37, Issue 3, April 2026.
ABSTRACT Researchers often use offsets to control for variation in exposure or effort in GLMM‐style models for count data. In this paper, we study the case where effort is dependent on the underlying process of interest (e.g., Poisson intensity) and where inference focuses on prediction. We first examine a simple Poisson GLM, where we use simulation to
