I am an Associate Professor at the Biogeography Department of Trier University, Germany, and the PI of serveral research projects related to

- species genesis and delimination, including geographic range exploitation

- character evolution, in particular traits related to aposematism

- ecological niche exploitation and change

- biological response to past climate change and to the Anthropocene 

- the impact of invasive species and pathogens

Focal study regions are rainforests of South America, but also our 'back garden' in central Europe. Our key organisms are amphibians. Among our main study groups are poison frogs (Dendrobatidae), harlequin toads (Atelopus) and European land salamanders (Salamandra). But these are not exclusive, as we also investigate reptiles, invertebrates or others. We study species and their environments at different spatial, temporal and taxonomic scales.

In an interdisciplinary frame, our lab may best be seen at the interface of systematics, ecology, biogeography, evolution and conservation. Methodically, we make use of molecular phylogenies, GIS applications, modelling etc. and process lab, experimental and field data. We very much like collaborative work.

Lötters is an editor of PLoS ONE and Salamandra. He is member of the IUCN Species Survival Commission, the 'Biodiversity, GMO-Monitoring and Risk Management' committee of VDI, and he is co-speaker of the 'Arbeitskreis Biogeographie'. He was an editor of Biotropica, a member of the International Committee of the World Congress of Herpetology and the vice-president of the German Herpetological Society DGHT.
