Yet formal tests of this hypothesis have been elusive owing to the difficulty of firmly establishing the relationship between species traits and evolutionary “fitness” for a group of related species that recently diverged from a common ancestral species.</p> Mon, 08 Jan 2024 17:39:45 +0000 webfull 196195 at /channels /channels/channels/news/uncovering-underlying-patterns-contemporary-evolution-336562 <p>Wild populations must continuously adapt to environmental changes or risk extinction. For more than fifty years, scientists have described instances of “rapid evolution” in specific populations as their traits (phenotypes) change in response to varying stressors. For example, Spanish clover has developed a tolerance for copper from the mine tailings in which it grows, and the horn size of Alberta bighorn sheep has decreased due to trophy hunting.</p> Tue, 18 Jan 2022 20:30:00 +0000 webfull 176624 at /channels /channels/channels/news/quantifying-evolutionary-impacts-humans-biosphere-harder-it-seems-290559 <p>Are human disturbances to the environment driving evolutionary changes in animals and plants? A new study conducted by ƻ����Ժ researchers finds that, on average, human disturbances don’t appear to accelerate the process of natural selection. While the finding may seem reassuring, this unexpected pattern could reflect the limited number of species for which data were available.</p> Fri, 12 Oct 2018 14:05:47 +0000 webfull 141932 at /channels /channels/channels/news/nature-how-warp-speed-evolution-transforming-ecology-284360 <p>Even for the most common processes, such as changes in population size or food chains, ecologists must take evolution into consideration, researchers say. “Everybody realized rapid evolution was occurring everywhere,” says evolutionary ecologist Andrew Hendry of ƻ����Ժ.</p> <p><a href="https://www.nature.com/articles/d41586-018-01400-y">Nature</a></p> Wed, 31 Jan 2018 19:08:58 +0000 webfull 134638 at /channels /channels/news/grant-monitor-environmental-change-252131 <p> Wed, 20 May 2015 15:59:49 +0000 webfull 110062 at /channels /channels/news/why-do-some-fish-thrive-oil-polluted-water-258096 <p><strong><em>By Melody Enguix</em></strong></p> <p><strong><a href="/newsroom">ƻ����Ժ Newsroom</a></strong></p> <p>When scientists from ƻ����Ժ learned that some fish were proliferating in rivers and ponds polluted by oil extraction in Southern Trinidad, it caught their attention.
