We observed differences in den types, den site characteristics, and chronology of denning between radiocollared brown bears (Ursus arctos) and Asiatic black bears (U. thibetanus) on and near the Sikhote-Alin Biosphere Zapovednik in the Russian Far East during 1993-2002. Of 27 Asiatic black bear dens, 17 (63%) were in hollow trees, 6 (22%) in ground nests, 3 (11%) in caves or under rocks, and 1 (4%) was in an old excavated brown bear den. Of 12 brown bear dens, 9 were burrows excavated into hillsides, 2 under rock outcroppings, and 1 was a ground nest. We compared elevation, percent slope, aspect, and location on slope of 20 brown and 31 Asiatic black bear dens between species, sexes, and with 100 random coordinates, used to represent availability. Brown bears denned at higher elevations and on steeper slopes than Asiatic black bears and selected higher elevations and steeper slopes than were generally available. Black bears selected flat areas more often than available. Female black bears emerged from dens later than did males, and female black bears with cubs emerged later than barren females. One brown and 1 Asiatic black bear abandoned dens in response to inves- tigator disturbance. While in dens, 1 Asiatic black bear was killed by a tiger (Panthera tigris) and 2 other Asiatic black bears survived predation attempts, one by a tiger and one by a brown bear. Tree dens may be important for Asiatic black bears for protection against predators. To increase survival and repro- duction, we recommend protecting potential den trees from logging and adjusting hunting seasons and practices to reduce mortality of adult females.

Born and raised near Boston, Dale Miquelle has degrees from Yale University (BS), the University of Minnesota (MS), and the University of Idaho (PhD). Miquelle worked in Alaska and Nepal prior to his arrival in Russia in 1992, when he joined the Sikhote-Alin Biosphere Reserve and Hornocker Wildlife Institute’s Siberian Tiger Project (now part of the Wildlife Conservation Society.) Miquelle is the Country Director for WCS’s Russia Program, and coordinates research and conservation actions to protect large carnivores and the ecosystems upon which they depend, focusing mainly in Northeast Asia.

Dr Dale Miquelle is a world authority on Siberian tigers.

In 1992 Dale had intended to spend only a couple of years in Russia but was so moved by his first encounter with a wild Siberian tiger he has devoted more than 20 years of his life to them. Dale has been leading research and conservation efforts on the Siberian tiger since 1992. He is currently director of the Wildlife Conservation Society’s Russia program which is the worlds longest running field research project on tigers.

He assisted in the creation of new protected areas in both China and Russia and has provided a vision for recovery of tigers across north-east Asia. More recently his efforts have focused on developing the next generation of tiger conservationists in the region by creating the Sikhote-Alin Research Center and developing an internationally recognized research and training program for international students.

“An answer to the question ‘Can we save the Siberian tiger?’ is really the answer to an even starker question - ‘can we save ourselves? If we as a global community cannot find the space and the means to save tigers, the odds of saving ourselves are indeed poor.”

Posted by the Fake professor: 04 - CONTRADICTORY INFORMATION (researchers)

The lack of clarity on the outcome of disputes near kill-sites is a result of a lack of specific information on one hand and contradictory statements of researchers on the other hand.

Miquelle, for instance, stated adult tigers are not always able to defend their kill against male brown bears (1) and brown bears have been known to kill tigers (2), but he also stated brown bears do not win all encounters, as some tigers had learned to hunt them (3). Which is not easy to understand, as there is a difference between open encounters and ambushes. His statements differ from Kostoglod´s, who (posts 164, 182) stated brown bears are capable to kill tigers (4). Rukovsky, on the other hand, stated an average tiger is always stronger than an average bear (5) and tigers won most of the fights he knew of (6). He, however, also mentioned an incident in which a young adult male tiger (post 70), after a prolonged battle, was killed by a very large brown bear (7).

The confusion not only is a result of a lack of specific information and contradictions. It also is likely the shape and the outcome of an encounter depends on the gender, age and size of both animals involved (8). In many cases, this information is lacking.

Finally, it has to be stated the observations of modern research regarding the relation between tigers and bears do not confirm those of Kaplanov and Bromlej. Kaplanov, from the tracks in the snow, saw brown bears, one of these a very large animal, avoid tiger tracks (9), whereas modern researchers state brown bears often deliberatey follow the tracks of tigers (10). Bromlej stated tigers hunted even large hibernating brown bears (11), of which the largest were able to escape, but his observations were not confirmed by modern research (12).

*Let's break this down:

(1) Miquelle, for instance, stated adult tigers are not always able to defend their kill against male brown bears (1) and brown bears have been known to kill tigers (2), but he also stated brown bears do not win all encounters, as some tigers had learned to hunt them (3). Which is not easy to understand, as there is a difference between open encounters and ambushes.
_________________________________________________

A - Adult tigers are not able to defend their kill against a full-grown male brown bear.
B- Brown bears have been known to kill tigers.
C- Tigers only hunt adolescent and female brown bears, therefore the bears do not win all encounters.
_________________________________________________

(2) His statements differ from Kostoglod´s, who (posts 164, 182) stated brown bears are capable to kill tigers (4). Rukovsky, on the other hand, stated an average tiger is always stronger than an average bear (5) and tigers won most of the fights he knew of (6). He, however, also mentioned an incident in which a young adult male tiger (post 70), after a prolonged battle, was killed by a very large brown bear (7).
_________________________________________________
 
A- Brown bears are capable to kill tigers. 
B- An average tiger is always stronger than an average bear. (a misquote) A tiger will always choose a bear smaller than himself as prey. 
C- Tigers win most "fights" with the bears they ambush. 
D- A young adult male tiger was killed by a large brown bear. Possibly he ambushed a large she-bear, who overpowered the young tiger or the young tiger (like a teenager) was foolish and challenged an adult male brown bear over a carcass. 
_________________________________________________
 
A full-grown male brown bear has no fear of tigers; it is the tiger who fears this bear.

Don't know why this is doubled?

Neither do I. Probably a glitch.
