Abstract

Mangroves are costal environments that provide several ecosystem services to adjacent ecosystems due to its high productivity and protection against the tide. However, despite of its importance, this ecosystem is in great risk of disappearing. Due to the high productivity and deposition of allochthonous organic matter, the carbon cycling in mangroves is one of the most important ecosystem service not only for the mangrove, but to adjacent ecosystems that receive exported carbon and in a global scale, due to the negative effect of mangrove loss. Therefore, comprehending the dynamics of organic matter decomposition on mangrove sediments, from the ecological succession that occur in it, and the genes involved in the process of degrading this material, is of outstanding importance in the moment in which global climate change threatens the survival of this ecosystem. For this reason, this project aims to evaluate the community dynamics taking place during the decomposition of plant organic matter in mangrove sediments; determining the microbial community composition and greenhouse gas emissions in sediments with different degrees of preservation how this process that place and how the anthropic impact and climate change affects it. Additionally, this project aims to identify by the means of metagenomics and metatranscriptomics the metabolic routes involved in organic matter degradation in these sediments. The bottom line knowledge this project searches is to connect phylogenetic and metabolic biodiversity with the process of plant organic matter decomposition in mangroves. Therefore allowing to identify how climate change can disrupt the functioning and which would be the global effect of it. (AU)
