Soil microalgal communities on an antarctic active volcano (Deception Island, South Shetlands)
Contemporary eruptive episodes and present volcanic activity at Deception Island have created a mosaic of different environmental conditions. In this study, the microalgal communities inhabiting 18 sites differing in geology, degree of disturbance and physico-chemical features (texture, water, organ...
