Response of rhizosphere microbial communities associated with Antarctic hairgrass (Deschampsia antarctica) to UV radiation
The response of rhizosphere microbial communities associated with natural populations of Deschampsia antarctica growing on Leonie Island (67degrees36'S, 68degrees21'W, Antarctic Peninsula) to UV radiation was investigated. UV radiation was controlled in the field using Perspex VA screens (...
