The recent advances in molecular biology opened exciting new opportunities for studies of the interface of ecological, evolutionary and genetic mechanisms to understand the evolution of adaptations in organisms. I propose to study the ecological pressures in natural populations that influence the patterns of variation at the genomic level and result in adaptive changes. I will study adaptations to abiotic factors, as well as adaptations to ecological interactions and coevolution. I will study natural populations of genetic model organisms (flies in the genus Drosophila). This grant will support a new research program in ecological genomics of insects at Universidade de São Paulo (where I have been recently hired), and will allow the collection of natural populations, experimentation in the laboratory and in the field, including the use of modern tools of Drosophila genetics and the use of next generation sequencing. I propose four studies that will investigate important questions in evolutionary biology, and will also produce a solid foundation of results that will open the opportunity for a variety of future studies. Additionally, this project will generate important resources such as lines collected in different populations, identification of genes responsible for important phenotypic traits, genomic sequences and information about the diversity of natural enemies of drosophilids in the field. This project will be developed in collaboration with Professors Douglas Futuyma and Walter Eanes (Stony Brook University), Frank Jiggins and Ben Longdon (Cambridge University), and Paulo R. Guimarães Jr and Carlos R. Vilela (USP). (AU)
