“…In addition, these islands are the most inhabited by seabirds and have a significant population of penguins. The high concentrations of nitrogen compounds observed could also come from the ornitogenic soils that surround the glaciers [ 27 ].…”

“…This procedure greatly enhances nutrient availability, especially P and N. Some notable nesting zones are located in the South Shetland archipelago, especially on Deception and Barrientos islands. These two areas with ornithogenic soil are quite close to the ROJ and MAC glaciers in Deception Island [ 48 ], and QUI in Greenwich Island [ 27 ], sampling points 1, 2, and 6 respectively ( Figure 7 ). In this type of soil, several bacterial species were identified, for example, Clostridium frigoris [ 48 ], the most abundant species in QUI samples ( Table S4 ).…”

“…Áreas com solos ornitogênicos constituem o local mais importante de sequestro de carbono na Antártica (SIMAS et al, 2007). Nestes ambientes, ricos em nutrientes, tem-se favorecimento ao crescimento da vegetação (TATUR;MYRCHA, 1984;MICHEL et al, 2006;SIMAS et al, 2007;SIMAS et al, 2015;DAHER et al, 2018).…”

“…Os resultados encontrados por essas pesquisas têm comprovado que a região da Península Antártica e o Arquipélago das Shetlands do Sul apresentam maiores temperaturas e precipitação em comparação com outras partes da Antártica (Vieira et al, 2010;Chaves et al, 2017), propiciando estabelecimento mais efi ciente de processos pedogenéticos e a consequente consolidação de sistemas periglaciais (Francelino et al, 2011;Moura et al, 2012). Os principais processos de formação de solo atuantes na região incluem a translocação de argilas, o tiomorfi smo, podzolização e a fosfatização (Simas et al, 2007;Simas et al, 2008;Pereira et al, 2013;Michel et al, 2014;Lopes et al, 2017;Daher et al, 2019). A diversidade pedológica está relacionada principalmente à diversidade do material de origem, colonização biológica atual e pretérita, e ocorrência e distribuição do permafrost (Simas et al 2008;Moura et al 2012).…”
