No selection on immunological markers in response to a highly virulent pathogen in an Arctic breeding bird
In natural populations, epidemics provide opportunities to look for intense natural selection on genes coding for life history and immune or other physiological traits. If the populations being considered are of management or conservation concern, then identifying the traits under selection (or ...
