Christoph Liedtke Dept. Ecología de Humedales Estación Biológica de Doñana (CSIC) Title: The Evolution of Terrestrial Breeding in African Amphibians Abstract: The transition from aquatic to terrestrial reproduction in early tetrapods is viewed as a major adaptive change in the history of life. Extant amphibians are an interesting group for testing how such a shift may have occured, given the multiple, independent evolutionary changes towards terrestrial breeding in this group. Many amphibian species show partly or fully terrestrial modes of reproduction and their spatial distribution correlate with specific life history traits as well as climatic and environmental factors. Phylogenetic comparative methods provide a powerful tool for investigating such evolutionary correlations and in this seminar, I will use two examples from Africa: the fauna of the speices-rich Eastern Arc Mountains of Tanzania and the diverse African colonizers, the true toads, to test hypotheses on the evolution of terrestrial life history strategies, their effect on evolutionary rate dynamics and on evolutionary lineage diversification
