Young bears exhibited fewer stereotypies than adult ones, especially if these adults were kept indoor at night.
Bears exhibited lower HRV, an indication of stress, when they were close to human settlements and especially during the berry season, when humans were more often in the forest, picking berries and hunting.
Analyses of the genomes of brown bears exhibited substitutions that may alter the function of proteins that regulate glucose uptake, which could be beneficial when feeding on carbohydrate-dominated diets during hyperphagia, followed by fasting during hibernation.
The behavioral plasticity that polar bears exhibit is also relatively profound compared to many zoo animals cared for in these natural history institutions.
Polar bears exhibit reduced premolars and molars in comparison with most other ursids [1] but also lack the well-developed shearing blade-like teeth of hypercarnivores [1], [23].
For example, polar bears exhibit reduced surface area of the grinding molar teeth, a feature normally pronounced in more omnivorous ursids, and a low, slender skull [1], [2].
Free-ranging brown bears exhibit highly contrasting physiological states throughout the year.
This pattern could be caused by bears exhibiting fidelity toward certain clearcuts within their home ranges, due to successful foraging experience and higher security.
Thus, our genome phylogeny was robust with either outgroup, though the spectacled bear, exhibiting the least phylogenetic noise, appears a more favorable outgroup for Ursidae in terms of overall support levels.
Torval (Damien Ryan) is a droning, ponderous and surprisingly sexy bore who exhibits streaks of nastiness while revealing the social anxiety that underpins his hectoring tones.
Mr. Kaskey was quoted in news articles today as saying the bear had exhibited "classic predatory behavior" and was "out to eat" the young hiker.
