Diversity and Keratin Degrading Ability of Fungi Isolated from Canadian Arctic Marine Bird Feathers
We present the first records of fungi associated with feathers from seabirds and sea ducks in the Canadian Arcticand sub-Arctic. Birds sampled in Nunavut and Newfoundland (Canada) included the Common Eider (Somateria mollissima), King Eider (S. spectabilis), Black-legged Kittiwake (Rissa tridactyla)...
