Bumblebees acquire a taste for pesticide-laced food as they become more exposed to it, a behaviour showing possible symptoms of addiction. This study of bumblebee behaviour indicates that the risk of pesticide-contaminated food entering bee colonies may be higher than previously thought, which can have impacts on colony reproductive success. In research published today in … Read more
During their annual migration to wintering sites in Mexico, monarch butterflies encounter dangers ranging from cars and trucks to storms, droughts and predators. A study led by ecologists at the University of Georgia has found evidence that these iconic insects might be facing a new challenge. At sites along their migration route, some migrants encounter … Read more
Biological anthropologists from The University of Texas at Austin have described three new species of fossil primates that were previously unknown to science. All of the new primates were residents of San Diego County at a time when southern California was filled with lush tropical forests. Since the 1930s, numerous primate fossils have been uncovered … Read more
