| The Caatinga is a biome located in a semiarid region of northeastern Brazil. It consists of various ecosystems, presented a unique environmental system of this country. Because it is an environment with unique characteristics, recent studies have revealed the private wealth of this biome in terms of microbial biodiversity. Microorganisms found in this habitat may present specific mechanisms to ensure their survival in this environment that provides extreme conditions, such as temperature changes, intense solar radiation and hydrous stress. Because of these different mechanisms used by different microorganisms, becomes an enabling environment to search for new enzymes and bioactive substances produced by these organisms can present different... |

| Abstract: Leaf decomposition is the primary process in release of nutrients in the dynamic mangrove habitat, supporting the ecosystem food webs. On most environments, fungi are an essential part of this process. However, due to the peculiarities of mangrove forests, this group is currently neglected. Thus, this study tests the hypothesis that fungal communities display a specific succession pattern in different mangrove species and this due to differences in their ecological role. A molecular approach was employed to investigate the dynamics of the fungal community during the decomposition of three common plant species (Rhizophora mangle, Laguncularia racemosa, and Avicennia schaueriana) from a mangrove habitat located at the southeast of Brazil. Plant... |

| Mangroves are costal ecosystems known for its important role as sink and source of organic matter. This ecosystem covers most of the tropical and subtropical shores. A major portion of the organic matter that is produced by the mangrove vegetation is exported to nearby marine ecosystems. Therefore, this study was designed to shed light over the process of litter decomposition by using high throughput sequencing of the mRNA and DNA present in decaying mangrove leaves. With this purpose, litter bags contatining leaves of Laguncularia racemosa, Avicennia schaueriana and Rhizophora mangle were left on the mangrove sediment for 60 days. This experiment was conducted in three different mangroves in different locations. These material was had its total DNA and... |

| Mangroves are dynamic and unique ecosystems which provide important ecological services to coastal areas. The phylloplane is one of the greatest microbial hosts and most of their microorganisms are uncultivated, thus having the potential to house novel bacteria species. Bacterial community structure of L. racemosa phylloplane, a well-adapted mangrove species with salt exudation at foliar levels, was accessed through 16S rRNA amplicon sequencing. Sampling was performed at Cananéia mangrove in São Paulo state, Brazil in three different sites across a transect from the upland to the seashore. There was significant effect of the sites in the bacterial microbial community along the transect. Higher diversity was observed in intermediary locations between the... |
