Food Subsidies Reduce Livestock Depredations by a Recovering Carnivore

open access: yesAnimal Conservation, EarlyView.
Diversionary feeding—providing food caches to divert predators away from preying on livestock—is a strategy to reduce depredations by Mexican gray wolves but has not been evaluated for its effectiveness. We used data from the Mexican wolf recovery program from 2014‐2021 to evaluate whether diversionary feeding reduced livestock depredations by wolf ...

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

open access: yesActa Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

An investigation on the bear damages and reasons in Artvin [PDF]

open access: yes, 2010
Artvin yöresi oldukça zengin bir yaban hayatı ekosistemine sahiptir. Bu ekosistemin en önemli öğelerinden birisi de Boz Ayı (Ursus arctos L.)’dır. Son yıllarda Artvin yöresinde ayı zararlarının arttığı yönünde yaygın bir kanaat oluşmuştur. Bu çalışmayla,

Identifying key denning habitat to conserve brown bear (Ursus arctos) in Croatia [PDF]

open access: yes, 2017
CONTEXT: The preservation of denning habitat is paramount to the recovery of threatened bear populations because of the effect that den site disturbance can have on cub mortality.

Exploring dietary adaptations in Ursus minimus: a 3D geometric morphometric analysis of the mandible

open access: yesBoreas, EarlyView.
Using 3D geometric morphometrics, the dietary adaptations of the extinct Auvergne bear (Ursus minimus) are analysed. Its mandibular morphology aligns more closely with omnivorous rather than insectivorous bears, challenging current ideas. The extinct bear Ursus minimus, which lived in Europe during the Pliocene and possibly Early Pleistocene, is ...

Osos pardos fósiles encontrados en cuevas de Portugal [PDF]

open access: yes, 1982
Este trabajo es una revisión de los robustos osos pardos fósiles encontrados a principios de siglo en Portugal y publicados por E. Harle. Se comparan con formas fósiles españolas, que poseen dentición menos robusta y con esqueleto postcraneal equivalente,

Fossil bears break free from inhibitory cascade constraints at least twice (Ursus minimus and Ursus deningeri) caused by dietary adaptations

open access: yesBoreas, EarlyView.
Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.

Ecological plasticity of denning chronology by American black bears and brown bears

open access: yesGlobal Ecology and Conservation, 2019
Ecological plasticity may index the capacity of individuals, populations, and species to respond to stochasticity. Few studies have demonstrated mechanisms influencing expression of plasticity and less have addressed proximate and causal mechanisms at ...

New perspectives on head and neck allometry and ecomorphology in tetrapods

open access: yesBiological Reviews, EarlyView.
ABSTRACT The skull and neck are vital parts of the body, influencing feeding ecology, habitat exploitation and locomotion. Numerous studies have therefore sought to understand how the size of these segments vary with ecology and scale with overall body size.

Black bear density in Glacier National Park, Montana

open access: yesWildlife Society Bulletin, 2014
We report the first abundance and density estimates for American black bears (Ursus americanus) in Glacier National Park (NP), Montana, USA. We used data from 2 independent and concurrent noninvasive genetic sampling methods—hair traps and bear rubs ...
