Snow and glacier ecosystems across remote Antarctic island reveal hidden microbial diversity

climate_change Antarctic Research Microbial Diversity

Researchers from the University of Bristol identified a diverse range of microbial algae communities on Signy Island in Antarctica. The study suggests that Antarctic glacier ecosystems may respond differently to global warming than those in the Northern Hemisphere.
