Bear and Lynx intetereactions

[Montezuma]

Brown bears, or perhaps black bears, intreact with Lynxes across the northern globes. Bears, due to their larger size always dominate Lynxes and these unfortunate cats lose a lot of prey to them. Here are some studies showing Bear-Lynx intereaction in North America, Europe and Eurasia.

Bear kleptoparasitism is negatively effecting lynx in Slovenia

"Bears steal between 8% – 74% of lynx prey. The rate also depends on bear movement rate and proximity of supplementary feeding sites. For example, up to 1 km away from the feeding sites, the odds for kleptoparasitism are five times higher. Thus, by supplementary feeding bears the negative effect bears have on lynx is strongly increased. Furthermore, supplementary feeding shortens the bear denning period, which further increases lynx prey losses."

"Bears are stealing lynx’s prey, which leads to lynx increasing their kill rate by 23%. This could have a negative impact on lynx population, as together with a higher risk of hunting injuries it could lead to lower lynx survival."

"Brown bears in Europe not only steal between 40 and 60 percent of Eurasian lynx kills, but run the cats off. The rate lynx lose food to bears is so high Prugh refers to it as a “bear tax.”

"Furthermore, the presence of a bear feeding site increased the odds of lynx losing kills by 5-fold compared to areas>1000 m from these sites. We suggest that existing bear-feeding regimes should be reconsidered in order to reduce unwanted side-effects of this controversial practice on endangered apex predators. We also call attention to the importance of considering impacts of interspecific interactions in wildlife management and conservation.Overall, we observed that bear scavenging pressure resulted in substantial energetic losses for Eurasian lynx. The probability of lynx losing kills to bears ranged from 8 to 74% and strongly depended on local bear densities and monthly bear movement rates. Kleptoparasitic interaction intensity differed almost 3-fold between different bear management zones."

"It has also been suggested that scavenging by bears may have been an important factor in shaping felid patterns of prey selection toward smaller prey and results in consequent morphological and behavioral adaptations of predators during the evolution of some felids, like the genus lynx."

"IN THE SIKHOTE-ALIN NATURAL RESERVE, THERE WAS A CASE IN EARLY FEBRUARY WHERE A BROWN BEAR THAT WAS NOT HIBERNATING TRACKED A LYNX, THEN FOUND ITS KILL, A YOUNG INDIVIDUAL OF THE MANCHURIAN WAPITI, AND ATE IT DURING THREE DAYS."
