The composition of some of our nation's forests may be quite different 200 to 400 years from today according to a recent study at the University of Illinois. The study found that temperature and photosynthetic active radiation were the two most important variables in predicting what forest landscapes may look like in the future. The uncertainties became very high after the year 2200.

The team led by Denis Reale, a professor in the Department of Biological Sciences at UQAM and Canada Research Chair in Behavioural Ecology, recently completed a study showing the link between personality, survival and reproductive success in male bighorn sheep. Their results were published in an article entitled "Male personality, life-history strategies and reproductive success in a promiscuous mammal" in the prestigious Journal of Evolutionary Biology 22(8): 1599-1607. In addition to being a significant advance in our knowledge of these mammals, the research offers insight into personality differences in animals and humans, from an evolutionary perspective.

Virginia Commonwealth University School of Medicine researchers have discovered a gene involved with the production of sperm that may contribute to male infertility and lead to new approaches to male contraception.
