In recent years, archaeal diversity surveys have received increasing attention. Brazil is a
country known for its natural diversity and variety of biomes, which makes it an interesting …

Aims: To evaluate archaeal diversity in natural and impacted habitats from Rio de Janeiro
state, Brazil, a tropical region of South America. Methods and Results: 16S rRNA gene was …

This study focused on the structure and composition of archaeal communities in sediments
of tropical mangroves in order to obtain sufficient insight into two Brazilian sites from different …

Polymerase chain reaction (PCR) assays targeting 16S rRNA genes followed by DNA
sequencing are still important tools to characterize microbial communities present in …

We evaluated the co-occurrence of archaeal taxonomic groups and soil physicochemical
characteristics in relation to the structuring of the archaeal community in Amazonian soil …

The Cerrado is a biome that corresponds to 24% of Brazil's territory. Only recently microbial
communities of this biome have been investigated. Here we describe for the first time the …

Natural ponds in the Brazilian Cerrado harbor high biodiversity but are still poorly studied,
especially their microbial assemblage. The characterization of the microbial community in …

The Archaea domain is ubiquitously distributed and extremely diverse, however,
environmental factors that shape archaeal community structure are not well known. Aquatic …

Mangroves are complex ecosystems that regulate nutrient and sediment fluxes to the open
sea. The importance of bacteria and fungi in regulating nutrient cycles has led to an interest …

We used 16S rRNA sequencing to assess the archaeal communities across a gradient of
Cerrado. The archaeal communities differed across the gradient. Crenarcheota was the …
