Evolution of snow algae, from cosmopolitans to endemics, revealed by DNA analysis of ancient ice
Abstract Recent studies of microbial biogeography have revealed the global distribution of cosmopolitans and dispersal of regional endemics, but little is known about how these processes are affected by microbial evolution. Here, we compared DNA sequences from snow/glacier algae found in an 8000-yea...
