Living amphibians are the direct descendents of the first group of vertebrates to come on to land. Yet, they continue to be tied to fresh water, primarily for their reproduction. This makes them fairly unique amongst tetrapods and a fascinating group of organisms. They have also evolved other, intriguing traits and we, at the Ecology, Evolution and Development Group of the Biological Station of Doñana, are interested in applying different approaches to studying trait evolution at different scales.I am Christoph Liedtke, and I am interested in studying trait evolution in amphibians at different scales. From broad patterns in evolution across species, using comparative phylogenetic methods, down to the molecular mechanisms underlying plastic phenotypic changes, using transcriptomics and genomics. I am a researcher at the Biological Station of Doñana, Spain, and I received my PhD from the University of Basel, Switzerland. More on my background here.
