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. Which is the final goal of this project, to unveil the biodiversity associated with the decomposition of plant organic matter in mangroves allowing to identify the anthropogenic effects that can disrupt this ecosystem functioning and further contribute to climate changes.
