Abstract

Species are the fundamental unit of contemporary biology. The accumulation of microevolutionary modifications through time drives the process of speciation, which is considered complete when gene flow ceases between diverging taxa. Sexual selection can facilitate this process by shaping morphological and behavioral characteristics of individuals leading to reproductive isolation. A bastion of biological diversity, the Atlantic Rainforest is an excellent setting in which to study the generation and maintenance of biodiversity. The genus Cycloramphus (Cycloramphidae) includes a number of anuran species endemic to the Brazilian Atlantic Rainforest that exhibit very specialized ecology and reproductive biology. Their unique life histories make them an interesting group for studies related to evolution. Our project will examine Cycloramphus at three microevolutionary scales: variation among species, among populations, and among individuals. We propose to study: (I) the molecular phylogeny of Cycloramphus, with the goal of developing a comprehensive phylogeny of the genus that will help us understand the evolutionary history of Cycloramphus and the origin of the ecological diversity within the genus; (II) the population genetics of two species that live partially in sympatry (C. boraceiensis e C. dubius), with a focus on interspecific gene flow and the reinforcement hypothesis; and (III) the mating system and parental relationships of C. boraceiensis, by examining correlations between reproductive success and adults traits, as well as the hypothesis of kin-bias recently described in a Cycloramphus sister genus.
