Explaining variation in songbird blood mercury using trophic level, foraging behavior, migratory behavior, and phylogeny
Increasingly, contaminants such as lead, mercury, and PCBs, make their way into water, soils, and the atmosphere where they impact animals and pose challenges for wildlife conservation. Environmental contaminants affect species differently, and furthermore, species bioaccumulate contaminants to varying degrees which may put certain species at greater conservation concern. Here we investigate interspecific variation in mercury bioaccumulation in songbirds. Mercury has been studied in songbirds previously; however interspecific variation in mercury levels is not fully understood. Although mercury ...
