Adaptation of mammalian host-pathogen interactions in a changing arctic environment
<p>Abstract</p> <p>Many arctic mammals are adapted to live year-round in extreme environments with low winter temperatures and great seasonal variations in key variables (e.g. sunlight, food, temperature, moisture). The interaction between hosts and pathogens in high northern latit...
