Comparative nasal and anal microbiomes in sympatric ringed and harbour seals: insights into host adaptation and niche differentiationComparative nasal and anal microbiomes in sympatric ringed and harbour seals: insights into host adaptation and niche differentiation [PDF]

Royal Society Open Science
Understanding the microbiomes of marine mammals is essential to explore their health, ecological roles and responses to environmental change. We investigated the nasal and anal microbiota of two sympatric subarctic seals, the harbour seal (Phoca vitulina)

Iliac Attachment of the Psoas Major Muscle: Anatomical Study of a Novel Muscle Attachment

Clinical Anatomy, EarlyView.
ABSTRACT The iliopsoas muscle is important functionally and is often encountered during various surgical procedures. During routine cadaveric dissection, a previously undescribed muscular structure was located deep to the iliacus muscle and coursed inferomedially to merge with the posterior aspect of the psoas major, running over the iliopectineal ...

Polar bear diet composition reveals spatiotemporal distribution of Arctic marine mammals across Nunavut, Canada

Ecological Indicators, 2021
Climate warming and associated physical and biological changes will likely force widespread species redistribution, particularly in polar environments. However, tracking such distributional shifts is difficult.

Functional Hematology of Ringed Seals (Phoca hispida) in the Canadian Arctic

, 1975
Hemograms from 20 netted and 6 shot ringed seals (Phoca hispida) were studied. Changes in red and white cell values in netted seals offer evidence for functioning sympathetic and adrenal–cortical stress pathways.

Movement Responses of Seals During Pile Driving for Offshore Wind Farm Construction

Animal Conservation, EarlyView.
Despite rapid growth of the renewable energy industry to meet climate change targets, predictions of population‐level impacts on wildlife are currently hindered by a limited understanding of individual behavioural responses to these developments.

Subspecies taxonomy reflects social and geographic patterns of taxonomic effort in tetrapods

Conservation Biology, EarlyView.
Abstract Subspecies have been used in conservation biology to account for intraspecific patterns in genetic diversity, which is crucial to long‐term population viability. Although over 3200 subspecies are currently assessed by the International Union for Conservation of Nature Red List, their biological relevance remains controversial.

Avian influenza overview June–August 2026

EFSA Journal, Volume 24, Issue 9, September 2026.
Abstract Between 5 June and 28 August 2026, 110 highly pathogenic avian influenza (HPAI) A(H5N1) virus detections were reported in domestic (7) and wild (103) birds in 12 countries in Europe. The number of detections remained at a seasonal low throughout the summer, continuing the decline observed since spring.
