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

Genomic analysis of expressed sequence tags in American black bear
BMC Genomics, 2010 Background Species of the bear family (Ursidae) are important organisms for research in molecular evolution, comparative physiology and conservation biology, but relatively little genetic sequence information is available for this group.

Ancient DNA reveals differences in behaviour and sociality between brown bears and extinct cave bears [PDF]
, 1997 Ancient DNA studies have revolutionized the study of extinct species and populations, providing insights on phylogeny, phylogeography, admixture and demographic history. However, inferences on behaviour and sociality have been far less frequent. Here, we

Boreas, 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.

PLoS ONE, 2013 Dramatic environmental changes associated with global cooling since the late Miocene, and the onset of glacial-interglacial cycles in the Pleistocene served as a backdrop to the evolutionary radiation of modern bears (family Ursidae). These environmental

Work minimization accounts for footfall phasing in slow quadrupedal gaits [PDF]
, 2017 Quadrupeds, like most bipeds, tend to walk with an even left/right footfall timing. However, the phasing between hind and forelimbs shows considerable variation.

Ecology and Evolution, Volume 16, Issue 4, April 2026.Black‐crowned night herons (BCNH) are a cryptic, widely distributed colonial wading bird. Despite showing regional declines in North America, this species has successfully adapted to colonize urban areas. In this study, our team used GPS/GSM transmitters to explore the space use, habitat use, and diel activity patterns of BCNH breeding at the largest ...

Wildlife Society Bulletin, 2016 The use of baits often increases success for many wildlife management activities, including wildlife capture for research, harvest by hunters and trappers during regulated activities, and lethal and nonlethal control for damage management.

Portable Electric Fencing for Bear Deterrence and Conservation
Human-Wildlife Interactions, 2018 Although bear-inflicted (Ursus spp.) human fatalities are rare in North America, human injuries, property damage, and bear mortalities occur wherever bears and humans commingle.
