Abstract

With the environmental changes caused by the climatic change expected in this century, organisms will need to adjust their distribution or adapt to the new conditions to survive. One of the most threatened ecosystems by the rapid global climate change, the mangrove, is dominated by unique plants, distributed in coastal regions of tropical and subtropical latitudes of the globe and has great socioeconomic and ecological importance. Despite this, in the last decades, this ecosystem was deeply affected by the intense urbanization and industrialization of the coastal zones, threatening its future. In this scenario, the identification of the abiotic factors that are determinant in the distribution of mangrove tree diversity can provide important information for conservation plans and for predicting the possible consequences of climate changes for species that dominate this ecosystem. The proposed project aims to identify the relative contribution of environmental and spatial variables to the structure of neutral and non-neutral genetic diversity of two mangrove species of the genus Avicennia along the coast of the South American continent. We will use single-base polymorphism (SNP) data distributed throughout the genome of individuals sampled throughout their distribution, and climatic and oceanographic data available from public databases in a Landscape Genomics approach. Through the results, we hope to generate information that can contribute to the prediction of species responses to climate change and to the definition of strategies for management, conservation and recovery of degraded mangroves.
