Unrecognized diversity and distribution of soil algae from Maritime Antarctica (Fildes Peninsula, King George Island)
Introduction: Eukaryotic algae in the top few centimeters of fellfield soils of ice-free Maritime Antarctica have many important effects on their habitat, such as being significant drivers of organic matter input into the soils and reducing the impact of wind erosion by soil aggregate formation.
