Abstract

Biogeochemical cycles in mangrove ecosystems are affected by biotic and abiotic factors, such as vegetation, climate and local geography. Expected climate and environmental changes in the next decades, such as increasing in frequency and intensity of storms, the accelerated sea level rise, and changes on ocean currents, will change sediments deposition rates and biogeochemistry cycles of coastal environments. The aim of this research proposal is to provide biogeochemical data of mangrove ecosystems located in the Northeast, Southeast and South of Brazilian coastline. These biogeochemical data will complement the information about mangrove dynamics research in similar Brazilian sites which are being studied by the FAPESP research project (2017/00334-1), coordinated by Professor Luiz Carlos Ruiz Pessenda. The past climatic and environmental mangrove conditions can be estimated by accessing biogeochemical records, through soil and tree-ring analysis of mangrove ecosystems by X-ray fluorescence spectrometry, associated to stable isotopes of C and N, pollen, 14C and 210Pb dating and texture data. Thus, this dataset will be helpful to improve predictive models related to mangrove ecosystems dynamics in the face of climate and environmental changes, such as precipitation, sea level rise and global warming.
