Antarctica allows at the same time to study the effects of change on the environment with minimal anthropic interference and in the least modified conditions in the world regarding biodiversity and its relations. At the same time, it allows assessing its effects on an ecosystem of few species and with a food web that directly links the oceans to terrestrial organisms. The South Shetland Islands are located further north within Antarctic Maritime and are therefore more vulnerable to climate change. Part of the studies already carried out with vegetation in this archipelago are discussed with a focus on the effects already generated and on predictions about future changes in the structure and plant diversity of Antarctica.

Bryophilous fungi have at least one stage of its life cycle linked to Bryophytes. There are few studies in relation to their taxonomy and ecology all around the world, including Brazil. The Agaricomycetes (Basidiomycota) have gained prominence worldwide and contained several species of economic interest. Based on a bibliographic review and discussion about identification methods and experimental models on this association a species list of bryophilous/Agaricomycetes found in Brazil was elaborated. In the works found among the techniques used to identify effective fungi/Bryophytes associations it can be cited: phylogenetics analysis, optical and electron microscopy, and cultivation experiments. In Brazil, four orders of Agaricomycetes (Basidiomycota), belonging to Agaricales, Boletales, Hymenochaetales, and Polyporales, with 33 species were found associated to Bryophytes in the literature. Information of the worldwide distribution of Brazilian muscicolous species and application of these groups were realized associating edibility, toxicity, and others. It was noted that in this country there is a scarcity of scientific knowledge of this subject, that needs to be better understood in terms of ecology and taxonomy.
