Ecosystems are a complex web of interactions. These ecological networks are being reorganized by extinctions and colonization events caused by human impacts, such as climate change and habitat destruction. In a paper published this week in Nature Ecology & Evolution, researchers from McGill University and University of British Columbia have developed a new theory to understand how complex ecological networks will reorganize in the future.
McGill Newsroom The research has implications for understanding human developmental disorders such as autism Adult songbirds modify their vocalizations when singing to juveniles in the same way that humans alter their speech when talking to babies. The resulting brain activity in young birds could shed light on speech learning and certain developmental disorders in humans, according to a study by McGill University researchers.
McGill Newsroom Guidance addresses key scientific, ethical, social, and policy challenges raised by new technologies and emerging areas of stem cell discovery and application
By Cynthia Lee, McGill Newsroom Life in the city changes cognition, behavior and physiology of birds to their advantage Birds living in urban environments are smarter than birds from rural environments. But, why do city birds have the edge over their country friends? They adapted to their urban environments enabling them to exploit new resources more favorably than their rural counterparts, say a team of all-McGill University researchers.
By Melody Enguix McGill Newsroom When scientists from McGill University learned that some fish were proliferating in rivers and ponds polluted by oil extraction in Southern Trinidad, it caught their attention. They thought they had found a rare example of a species able to adapt to crude oil pollution.
The popular dietary supplement ubiquinone, also known as Coenzyme Q10, is widely believed to function as an antioxidant, protecting cells against damage from free radicals. But a new study by scientists at McGill University finds that ubiquinone is not a crucial antioxidant -- and that consuming it is unlikely to provide any benefit.
The organisms commonly known as blue-green algae have proliferated much more rapidly than other algae in lakes across North America and Europe over the past two centuries – and in many cases the rate of increase has sharply accelerated since the mid-20th century, according to an international team of researchers led by scientists at McGill University.
Learning from others and innovation have undoubtedly helped advance civilization. But these behaviours can carry costs as well as benefits. And a new study by an international team of evolutionary biologists sheds light on how one particular cost – increased exposure to parasites – may affect cultural evolution in non-human primates.
Two renowned McGill University researchers are among the 14 winners of the 2014 Prix du Québec. Professor Michael Meaney, acclaimed for his achievements in the biology of child development, will be awarded the Wilder-Penfield prize. Professor Paul Lasko, a celebrated developmental biologist, will receive the Armand-Frappier award. The Prix du Québec is considered the most prestigious award attributed by the Government of Québec in cultural and scientific fields.
The Smithsonian Tropical Research Institute (STRI), the Panama-based branch of the Smithsonian Institution, will offset its carbon dioxide emissions by working with an indigenous community to conserve forests and reforest degraded lands with native tree species. The agreement was announced Sunday.
