Marco A. Molina-Montenegro, Cristian Torres-Díaz and Ernesto Gianoli Antarctic macrolichen modifies microclimate and facilitates vascular plants in the maritime Antarctica – a reply to Casanova-Katny et al. (2014) Journal of Vegetation Science 25
Here we provides evidence that the macrolichen Usnea antarctica can modify the microclimate, ameliorating the harsh conditions prevailing in Antarctica, establishing positive interactions with other lichens and mosses, and facilitating vascular species. Thus, this antarctic macrolichen would act as a 'nurse species', playing a key role in structuring the Maritime Antarctic plant community.
