I am currently working in the effects of condition dependence (environmental and genetic challenges) on the development of different morphological traits (ornaments, body size) and song traits in Gomphocerus sibiricus. On a broader perspective I want to assess and comprehend different aspects of the genetic architecture, G & B matrices, of sexually selected traits on Gomphocerus sibiricus. To achieve these and possible future goals I am combing field work in the Alps with laboratory work in Bielefeld.
I am very interested in the evolution of sexually selected traits, and especially in the conflict and coevolution between the sexes in the development of sexually selected traits. Specifically, I am interested in the evolution of traits that function as signals and on the influence of sexual signals on mate choice. Furthermore, I want to understand the changes in individual fitness when assessed from a senescence perspective. Finally, I am greatly fascinated by social wasps, spiders and birds, with which I have worked in the past and which I look forward to integrate in my research goals.
