Impact of Geese on the Limnology of Lakes and Ponds from Bylot Island (Nunavut, Canada)
Abstract Arctic freshwater ecosystems are important habitats for northern wildlife. Arctic climate impact studies suggest that global change could result in major modifications and perturbations of lakes, ponds and wildlife. Most studies focus either on freshwater ecosystems or on animal populations...
