• Abstract

  Overview: Species interactions can drive diversification. This is particularly true in cases of coevolved symbioses,where coevolutionary processes can lead to the generation and maintenance of novel functional andgenetic diversity as organisms respond to each over microevolutionary timescales. Furthermore, suchevolutionary coupling can lead to taxonomic diversification, as one or more p...

• Abstract

  The Dry Diagonal (DD) contains a number of environments including the Caatinga and Cerrado that span over 1/3 the area of Brazil, as well as the Chaco of northern Argentina. Because of its perceived lower biodiversity for many taxa than in better known biomes such as the Amazon basin and the Atlantic forest, evolutionary processes in the DD have received much less attention from biolog...

• Abstract

  This project will determine how secondary key innovations within the venom system contribute to diversification patterns in the advanced snakes and test for biases in the genetic pathways underlying rapid phenotypie evolution in venoms as a means for understanding the mechanism underlying the process of diversification in this diverse group. In the first part, we will test for relations...

• Abstract

  The project aims to investigate the insect-plant interaction between Eois moths and Piper species, with an emphasis on the characterization of olfactory proteins (ORs, OBPs, CSPs, IRs, GRs) involved in the attraction and recognition of host plants. The investigation of the transcriptome of the Eois sp antennas will allow the selection of olfactory receptors that will be functionally cha...

• Abstract

  The Cerrado is a patchwork of phytophysiognomies with dominance of savannah, placed in the Dry Diagonal, wide corridor in the center of the Neotropical region. Relate with one of the major world's hotspots to preservation and conservasion, with the minor percentage of protected areas in Brazil. It has 2,000,000 Km2 of size (24% of the brazilian territory), and high since sea level until...
