But new research from the University of Georgia shows that the summer population of monarchs has remained relatively stable over the … Read more

Bird populations in eastern Canada declining due to forest ‘degradation,’ research shows

Credit: CC0 Public Domain Bird species that live in wooded areas are under stress from human-caused changes to forest composition, according to new research led by Oregon State University that quantifies the effects of forest “degradation” on bird habitat. “Reducing forest loss has been the main focus of conservation policy to date, which is well … Read more
