We used serology and muscle digestion to test black bears (Ursus americanus) from western Oregon, USA, for Trichinella. Results indicate black bears in Oregon are not part of a sylvatic cycle for Trichinella, and risk of human exposure to Trichinella larvae from eating black bear meat from Oregon appears low.
We investigated reproductive ecology and cub survival of Florida black bears (Ursus americanus floridanus) in Ocala National Forest and the adjacent residential area of Lynne, Florida, USA, 1999–2003. We documented production of 81 cubs from 39 litters. Average litter size was 2.08 6 0.11 (SE) cubs. The mean age of first reproduction was 3.25 6 0.27 years. Excluding females that reproduced in c...
