- Molecular phylogeny of crustaceans and eu-arthropods based on multiple gene analyses
I started to work on crustacean, pancrustacean and euarthropod phylogeny with my PhD thesis. Basically starting from scratch I was lucky to collect all the non-malacostracan species by myself, like Pentastomida, Mystacocarida, Remipedia etc. However, it was kind of frustrating or enlighting (depending on your own philosophy, I am more the positive person and prefer latter perspective) that even with most complex modeling respectively the crustacean phylogeny was not clearly to recover despite that intensive, complete taxon sampling.
- Phylogeography of the species complex Zygaena angelica/transalpina
Speciation is still one of the topics that fascinates me. I was lucky to start working in this field with my master thesis and finally finish the study on diurnal zygaenid moths (Zygaenida, Lepidoptera) during my PhD. The species complex is, as many central european species, influenced by the effects during the last glacial. We could show that complex separation patterns and micro-refugia played obviously an important role to drive/undrive speciation.
- Diversity and monitoring of the local bat fauna of Bonn and the limestone quarries “Ofenkaulen”, Germany
My first contact to cave systems was terrestrial and caused by the monitoring work of winter shelters of bats in local quarry remainings in the mountain range “Siebengebirge” near Bonn. Additionally, monitoring by netting and detector work was conducted to describe and monitor the diversity of the local bat fauna.
- Primer-Tool-Box development for arthropods based on EST data
During my PhD degenerated primer sets were developed to sequence informative genes for arthropod subgroups based on aligned EST data and known informative genes . This approach was more extensively tested for crustaceans, however one outcome was that crustaceans are so diverse that primers sets had to be adapted in subsequent PCRs by manual testing, which was extremely time-intensive. The project was conducted in collaboration with the working group of Bernahrd Misof (Bonn, Germany), Günther Pass (Vienna, Austria) and Elisabeth Haring (Vienna, Austria).
