RESUMO:

Molecular data are currently the most important source of information to infer the evolutionary history of organisms. Phylogenetic relationships reconstructed from genetic data contribute to improving the inference of macroecological and biogeographic patterns, providing the necessary information for robust hypothesis testing using comparative biology methods. In this work, we had two main goals: 1) to investigate the molecular evolution rates of the mitochondrial genome of the family Vespertilionidae and, 2) to infer macroecological patterns of range size and climatic niche evolution of species belonging to the genus Eptesicus, using the previously inferred rates to calibrate a phylogeny for the genus. In the first chapter, we described the complete mitochondrial genomes of four Eptesicus species: Eptesicus brasiliensis, Eptesicus diminutus, Eptesicus furinalis and Eptesicus nilssonii. Furthermore, we inferred rates of molecular evolution of the mitochondrial genome of Vespertilionidae using fossil-calibrated Bayesian phylogenetic analyses. In the second chapter, we studied the relationship between morphological characteristics of Eptesicus species (as a proxy for dispersal capacity) and the evolution of their range size and climatic niche using a phylogenetically informed perspective. In face of the anthropogenic climate changes that the planet has been suffering, different species respond to such changes in different ways; one of these strategies is to disperse to more climatically suitable regions. Therefore, investigating how the climatic niche evolution patterns influence the current patterns of range size of a cosmopolitan clade, as is the case of the genus Eptesicus, and also taking into account the joint effect of dispersal capacity, can provide indications of which characteristics will most influence the ecology of these species in the future.
