“…Here, the most dominant bacteria were Proteobacteria, followed by Bacteroidetes and Planctomycetes. Benthic bacterial assemblages in sediment show typical dominance by Proteobacteria, which are characteristic of deep-sea microbiomes [ 53 ], but also dominate the water column in the Antarctica, comprising the vast and vital bacterioplankton community [ 54 , 55 ]. As also found here for sediments, the bacteria groups Alphaproteobacteria and Gammaproteobacteria dominate and are key colonisers of Antarctic surface and deep marine waters [ 54 , 56 , 57 ] which can thrive in areas with limited resources [ 58 ].…”

“…In general, seawater temperature can have the greatest impact on the diversity, abundance and structure of marine meiobenthic communities [ 50 ], and together with nutrient availability and chlorophyll-a it can impact significantly prokaryotic production and diversity [ 55 , 73 ]. In the Antarctic Peninsula coastal systems, abiotic factors such as seawater temperature and oxygen availability are described as one of the drivers of eukaryotic community structure, whereas silicates and salinity tend to be more important for bacteria [ 57 ].…”

“…Estudos realizados ao longo da costa da PAO (Murray e Grzymski, 2007;Luria et al, 2014;Signori et al, 2014;Ozturk et al, 2022) As arqueias são descritas com uma representação quantitativa menor em superfície do que bactérias e aumentando essa representação com a profundidade (Massana et al, 1998;Church et al, 2003). Um estudo conduzido no Estreito de Gerlache por Massana et al (1998) estimou 1-15% de Archaea na camada de mistura superficial, com aumento de 25% em 500 m de profundidade.…”

“…Um estudo conduzido no Estreito de Gerlache por Massana et al (1998) estimou 1-15% de Archaea na camada de mistura superficial, com aumento de 25% em 500 m de profundidade. Os principais táxons de arqueias pelágicas reportados na PAO foram relacionados ao filo Thaumarchaeota, com alta ocorrência de Nitrosopumilus e outras arqueias oxidantes de amônia (Signori et al, 2014;Hernández et al, 2015) e, em menor abundância relativa, Marine Groups II e III (classe Thermoplasmata) e classe Bathyarchaeia (Signori et al, 2014;Ozturk et al, 2022).…”
