Unveiling the paradox: revealing discordances between behavioral traits and evolutionary histories in Chorthippus species of the Alps
Sexual selection drives divergence in Chorthippus grasshoppers, leading to reproductive isolation through male song and female preference. In harsh Alpine environments, these barriers can weaken, resulting in hybridization and intermediate phenotypic populations, like Chorthippus brunneus ab. ticino. Discordances between the species’ behavior (song) and their evolutionary histories challenge traditional species taxonomic classifications based on male song, suggesting alternative explanations for the origins of intermediate phenotypes, such as phenotypic plasticity and introgression.

PhD student at the Leibniz Institute for the Analysis of Biodiversity Change in Bonn, specializing in Evolutionary Genomics and Population Genetics. Her current research focuses on the Population genetics and short-term evolution of the songbird germline-restricted chromosome. Recently completed a Master’s degree in Evolution, Ecology, and Systematics from LMU Munich with a broader interest in Conservation Genetics and Genomics. Proficient in both laboratory techniques and computational biology, she is dedicated to advancing our understanding of evolutionary processes and contributing to biodiversity preservation.
