“…During the last decade a considerable amount of soil, permafrost and geomorphological studies have been carried out in this region which is becoming warmer and wetter (Michel et al, 2006(Michel et al, , 2012(Michel et al, , 2014Navas et al, 2006Navas et al, , 2008Simas et al, 2006Simas et al, , 2007Simas et al, , 2008Schaefer et al, 2007;Serrano et al, 2008;Vieira et al, 2008Vieira et al, , 2010Vieira et al, , 2014Francelino et al, 2011;López-Martínez et al, 2012;Moura et al, 2012;Balks et al, 2013;Bockheim et al, 2013;Oliva and Ruiz-Fernández, 2015;Simas et al, 2015;Oliva et al, 2016). The relationship between landforms and soil distribution (Balks et al, 2013;Michel et al, 2014) and the distribution and changes of vegetation related to ice-free areas Pereira and Putzke, 2013;Guglielmin et al, 2014;Vieira et al, 2014) have been studied in detail in some areas.…”

“…The soil diversity and genesis have been described in relation to environmental conditions (Bolter 2001), and the soils of King George Island are considered to be the most developed in the whole of the Antarctic Peninsula (Simas et al . 2015). This is why they are of special interest in terms of evaluating their physical characteristics.…”

The soil microbiome was investigated at environmentally distinct locations on King George Island in the South Shetland Islands (Antarctic Peninsula) using 16 S rRNA gene pyrosequencing. The taxonomic composition of the soil prokaryotes (bacteria and archaea) was evaluated at three sites representing human-disturbed soils (Bellingshausen Station) and soils undergoing different stages of deglaciation (fresh and old moraines located near Ecology Glacier). The taxonomic analysis revealed 20 bacterial and archaeal phyla, among which Proteobacteria (29.6%), Actinobacteria (25.3%), Bacteroidetes (15.8%), Cyanobacteria (11.2%), Acidobacteria (4.9%) and Verrucomicrobia (4.5%) comprised most of the microbiome. In a beta-diversity analysis, the samples formed separate clusters. The Bellingshausen Station samples were characterized by an increased amount of Nostoc sp. and Janibacter sp. Although the deglaciation history had less of an effect on the soil microbiome, the early stages of deglaciation (Sample 1) had a higher proportion of bacteria belonging to the families Xanthomonadaceae, Sphingomonadaceae and Nocardioidaceae, whereas the older moraines (Sample 2) were enriched with Chthoniobacteriacae and N1423WL. Solirubrobacteriales, Gaiellaceae and Chitinophagaceae bacteria were present in both stages of deglaciation, characterized by genus-level differences. Taxonomic analysis of the abundant operational taxonomic units (OTUs) revealed both endemic (Marisediminicola antarctica, Hymenobacter glaciei) and cosmopolitan bacterial species in the microbiomes.

Este trabalho tem como objetivo compartilhar informações e reflexões sobre as pesquisas científicas geográficas realizadas na Antártica. A abordagem está fundamentada na visão de geógrafos que realizaram expedições antárticas como membros do Núcleo de Pesquisas Terrantar/UFV. Abordou-se sobre algumas possibilidades de regionalização da Antártica. Apesar de ser um território internacional destinado a paz e ciência, existem disputas geopolíticas. Os estudos sobre Geomorfologia possibilitam o monitoramento da dinâmica dos glaciares e que se faça reconstruções paleoambientais. Informações sobre os solos são importantes para registros de contaminações ambientais, monitoramento do permafrost, e auxílio na interpretação das paisagens exuberantes e cheias de mistérios. Análises climáticas nas sensíveis paisagens Antárticas são relevantes para melhor compreensão das mudanças climáticas. Massas de ar e correntes marítimas oriundas do continente influenciam nos regimes térmicos e precipitações na América do Sul. Estes conteúdos tem grande potencialidade de utilização no ensino de Geografia, podendo tornar as aulas mais atrativas e estimulantes.
