Traditional Chinese medicine draws heavily on animal products to the point at which it threatens the survival of tigers, rhinoceros and other large animals. It none the less has provided a number a leads for new drugs. Black bear bile is a particular source of active compounds. Tauroursodeoxycholic acid is already in use against human cholestatic disease, and 4-phenylbutyric acid has been approved for treatment of urea-cycle disorders. Other bile compounds could be used to treat type 2 diabetes, but all these materials, if they are to be widely used, require synthetic methods rather than the mass slaughter of black bears.

On May 23,1984, after parking my car in the parking lot on the east side of the School of Public Health at Johns Hopkins, I crossed Wolfe Street to enter the hospital. I took an elevator to the Anesthesiology Department, where I was to be injected with carfentanil, a drug that had been given to wild animals, such as black bears and bison, to immobilize them, but never before to humans. The goal of our research was to obtain a better understanding of the role that the opioid system played in pain, emotions, and addiction.

Ben Kilham knows firsthand about the social interactions of black bears and their cubs (Caputo, 2002). He acts as a surrogate mother to cubs orphaned when their mother either dies or abandons them because of an imminent threat to her life. The bear cubs he raises are sensitive, intelligent, and emotional creatures that need more than just food they also need security, affection, and someone to teach them. They learn about survival and they learn how to interact with each other and the world around them.

Pagoda dogwood Cornus alternifolia L.) - a flowering small tree growing up to 9 m tall, native to Eastern North America. The fruits are globular blue black drupes, eaten by birds and black bears. 

If you wish to punch me lets go to the bush, replied the rabbit. They disappeared in the bush. Soon screams and sounds of fighting could be heard from the bush. After a while, a smiling rabbit emerged from the bush. He was followed by a black bear and the wolf with a blue eye and a broken arm. The happy rabbit murmured then to himself it is not the subject of the thesis but who is your supervisor that matters. ... 

Following winter dormancy, black bears commonly forage on Douglas fir trees. This foraging appears to be selective as not all timber stands are utilized, and within stands, one tree may be stripped while its neighbor is ignored or merely sampled. An effort was implemented to determine whether bear selection is influenced by the chemical constituents present in the trees.
