Hibernation of the Black and Brown Bear Bobby Bennett Winter Ecology Field Course Spring 2006 Mountain Research Station University of Colorado, Boulder

Slide 2

Typical Hibernation Patterns Bears don\'t sustain for 7 months, living off muscle to fat quotients until late spring. They depend of their hide for protection, which pairs its protection limit in winter They build some kind of lair Both genders have a 99% survival rate in winter (Heinrich, p.76)

Slide 3

Hibernation Metabolic Processes of Both Species Heart rate may decrease to 8 thump/min Leptin, a hormone, controls craving amid hibernation A Satiety (Heinrich, p.256) Body temps drop to 35 degrees (37-38 when dynamic) Doesn\'t describe bears hibernation

Slide 4

Other Bodily Processes Water parity They as a rule don\'t urinate amid the winter Nitrogen squanders biochemically reuse once more into proteins as to not harm the bear This additionally anticipates bulk misfortune because of no activity (Heinrich, p.259)

Slide 5

Black Bear "Effectively sustenance molded; greatly sharp, animal of propensity; curious; energetic" (Brown, p.94) Brown Bear "Honorable; conscious, dauntless, strong, for the most part quiet; single" (Brown, p.94) Black and Brown Differences?

Slide 6

Black Bear Adds 4 in. of fat preceding hibernation Dens under substantial stones, scratched out despondencies under brush, in tree courses, caverns, under logs, conceivable in trees, under structures 20% steep incline (Brown, p.150) Brown Bear Adds 6-8 in. of fat preceding hibernation Dens delved in dry earth, under huge stones, situated above valley floor 30% steep slant Slope viewpoint depends of presentation 61% on north slant in Rocky Mnts. (Chestnut, p.150) Hibernation Differences

Slide 7

Hibernation Differences Cont. Chestnut bear sleeps as ahead of schedule as September in northern districts Black bears may not rest amid gentle winters (Brown, p.145)

Slide 8

conclusion Brown Bear and Black Bear have fundamentally the same as hibernation examples regardless of geographic extents The relatively bigger Brown Bear packs on more fat preceding hibernation There are contrasts in nook attributes for both species But… to the extent my exploration has driven me, both bears have fundamentally the same as hibernation/winter-time physiology and behavioral qualities What\'s Next? Considerably More Research
