"Sexual behaviour between primates of the same sex is part of the normal lives of some species and could play an important part in their long-term success. Researchers identified instances of same-sex sexual behaviour in 59 species of non-human primate, and suggest that it might be a response to harsh environments, predation and complex social hierarchies. "A lot of people have long regarded same-sex behaviour as an accident, or rare," says evolutionary biologist and study co-author Vincent Savolainen. But "it's part of the normal social life of primates"."
"Almost £5 million ($6.6 million) will be spent stashing contraceptive-laden hazelnut butter in special squirrel feeders to suppress the population of invasive grey squirrels ( Sciurus carolinensis) in the United Kingdom. Researchers have been working on a world-first contraceptive for grey squirrels and a prototype feeder that allows heavy greys to access the buttery bait, but prevents lighter red squirrels ( Sciurus vulgaris) from getting inside. If it works, the approach could be cheaper and more effective than culling at protecting the country's much loved rodents."
Same-sex sexual behaviour occurs in at least 59 non-human primate species and functions as part of normal social life rather than a rare accident. Such behaviour may serve adaptive roles in coping with harsh environments, predation and complex social hierarchies. The United Kingdom will spend almost £5 million to deploy contraceptive-laden hazelnut butter in selective feeders to suppress invasive grey squirrels while excluding lighter native red squirrels. The US Environmental Protection Agency will stop including human-health benefits in some cost–benefit analyses for air-pollution limits and will instead tally industry costs for regulating certain widespread toxic pollutants. New evidence offers clues about bird origins.
