The American Black Bear (Ursus americanus) as an Apex Predator: Investigating the Ecological Role of the World's Most Abundant Large Carnivore

open access: yesMammal Review, Volume 56, Issue 1, March 2026.
Black bears as apex predators. American black bears can (1) produce top‐down effects on ungulates equal to or exceeding those of typical apex predators and (2) modify the spatiotemporal behaviour of other carnivores, including pumas and coyotes. We argue that the term ‘apex predator’ is highly context dependent and not a species‐wide status.

Home Range and Habitat Selection of Chamois: A Systematic Review and Meta‐Analysis

open access: yesMammal Review, Volume 56, Issue 1, March 2026.
A systematic review of 22 studies reveals a research bias toward the Alpine chamois, leaving other subspecies understudied. Males occupy larger home ranges, and the species consistently selects steep, high‐elevation terrain while avoiding snow‐covered areas and human disturbance.

Anatolian ground squirrel (Spermophilus xanthoprymnus) retina: Comparative expression of synaptophysin, NeuN, calbindin‐D28k, parvalbumin, glial fibrillary acidic protein, and Iba‐1 during pre‐hibernation and hibernation

open access: yesThe Anatomical Record, Volume 309, Issue 2, Page 451-470, February 2026.
Abstract Hibernation induces significant molecular and cellular adaptations in the retina to maintain function under reduced metabolic conditions. This study aimed to investigate the expression of neuronal, synaptic, and glial markers in the retina of Spermophilus xanthoprymnus during pre‐hibernation and hibernation periods using immunohistochemical ...

A natural barrier: tick‐repellent potential of a spruce‐derived volatile blend against Hyalomma excavatum and Ixodes ricinus

open access: yesPest Management Science, Volume 82, Issue 2, Page 1481-1491, February 2026.
Both active and passive questing ticks, Hyalomma excavatum and Ixodes ricinus, were assessed for behavioural responses to two novel plant‐derived repellent volatile organic compound blends. Both tick species were repelled by the products, and both novo blends were significantly more repellent than currently available commercial products.

Transient 7‐hour coma following a sacrococcygeal epidural with ropivacaine in a cat

open access: yesVeterinary Record Case Reports, Volume 14, Issue 1, February 2026.
Abstract A 2‐year‐old cat was anaesthetised for pelvic fracture repair. Premedication included methadone 0.2 mg/kg and medetomidine 5 µg/kg intravenously (IV). Anaesthesia was induced with ketamine 2 mg/kg and propofol 1 mg/kg IV and maintained with isoflurane.
