Project groups


The extant groups of Pulmonata (Gastropoda) developed an enormous taxonomic diversity in the Cenozoic (in the last 65 million years). Changing climate and other ecological factors had an influence on the distribution and radiation of the major groups. Within this project the phylogeny and diversification of selected Pulmonata is investigated on the basis of mitochondrial and nuclear genetic markers. The proposed phylogenetic hypotheses will be used to assess the influence of climate changes in the Cenozoic on the evolution of the taxa under scrutiny.
