Abstract

Efforts to understand diversity patterns and processes at regional and global scales have been expanded due to anthropogenic impacts and the need for systematic conservation planning. Mangroves are considered strategic ecosystems in this preservation effort. Human impacts on these areas, including climate change, have received significant attention lately, especially because deforestation is occurring at an accelerated rate of 1-2% per year. This implies that if the current pace is maintained, the majority of these forests will disappear in this century. Additionally, macroecological pattern studies in marine ecosystems have primarily focused on how invertebrates exhibit different patterns. The objective of this project is to investigate the macroecological patterns of current and future mangrove invertebrate diversity (under climate change scenarios) in the West Atlantic. This project will use occurrence data, genetic diversity, and present and future environmental factors related to global warming. In order to answer questions about the influence of environmental factors on the phylogenetic diversity richness of invertebrates, patterns of diversity in latitudinal gradients, future species distribution predictions, and intraspecific genetic diversity, generalized linear models (GLMs), species distribution models (SDMs), and reduced genome sequencing technique (ddRAD-seq) for obtaining Single Nucleotide Polymorphisms (SNPs) will be employed. To identify regions with the highest concentrations of invertebrates and phylogenetic diversity of decapods, considered crucial for conservation. Furthermore, we seek to deepen the understanding of factors impacting these communities and predict future changes that will affect them. These results will be crucial in guiding management and conservation strategies, contributing to effective and sustainable mangrove community management. (AU)
