چکیده
Abstract There is considerable scientific interest as to how terrestrial biodiversity in Antarctica might respond, or be expected climate change. The two species of vascular plant confined the Antarctic Peninsula have shown clear gains density and range extension. However, little information exists for dominant components flora, lichens bryophytes. One approach has been look at change using altitude a proxy temperature previous results Livingston Island suggested that was controlling factor. We extended this study same site by chlorophyll fluorometers monitor activity microclimate lichen, Usnea aurantiaco-atra , moss, Hymenoloma crispulum . confirmed lapse rate but show changes water relations with probably main driver. were differences source U. benefitting from droplet harvesting performed substantially better summit. In contrast, duration, fluorescence photosynthetic modelling all desiccation large negative impact on lowest site. conclude are drivers along altitudinal gradient nutrients, not measured here, another possible contributor.

Background: In this article, it was analyzed how snow melting affects the assembly of lichen and moss communities in a small area of the coastal region of Barton Peninsula, which is in maritime Antarctic. In the small area, even though there is a huge gap of difference of the environment between the snow-filled area and snow-melt one, the latter did not have distinctive environmental gradients....
