Dr. Katharina Weiss
I am an evolutionary biologist, mainly working in the field of chemical ecology. My main interests lie in the evolution and maintenance of within- and between-species diversity and plasticity in sexually selected chemical signals in arthropods. Moreover, I want to integrate an organism`s ecology, its phylogenetic history, and environmental factors in investigating the evolution of these signals. Combining analytical methods like gas-chromatography/mass-spectrometry with behavioral assays, I currently investigate the condition dependence of chemical signals of females of the wasp spider Argiope bruennichi and the evolution of adaptive mating decisions of males based on these signals.
