I am an Associate Professor at the Biogeography Department of Trier University,
Germany, and the PI of several research projects related to
   - species genesis and delimitation, including geographic range exploitation,
   - character evolution, in particular traits related to aposematism,
ecological niche exploitation and change,
   - biological response to past and future landscape or climate change as well as
      to human impact including pesticide applications,
   - the impact of invasive species and pathogens.

Focal study regions are rainforests of South America and Africa 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), reed frogs (Hyperoliidae) 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 modelling, GIS applications, (molecular) phylogeny 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.

My ORCID (Open Researcher and Contributor ID) is orcid.org/0000-0002-7187-1968. I am also on Research Gate.

Europe Needs a New Vision for a Natura 2020 Network


Advocating this statement, members of our group have contributed to an important and widely acknowledged policy piece published under the interdisciplinary graduate school 'Cooperation of Science and Jurisprudence in Improving Development and Use of Standards for Environmental Protection – Strategies for Risk Assessment and Management’ at Trier University, funded by the German Science Foundation DFG (GRK 1319).

'Deutsche Bundesstiftung Umwelt' Book of the Month


Our group has contributed to a book on the status of amphibians and reptiles under climate change at the national scale. This work, published by the Biodiversität und Klima Forschungszentrum (BiK-F) and Climate Service Center (CSC), was honored as the book of the month in January by the 'Deutsche Bundesstiftung Umwelt', DBU.

Invited Speaker to 'German Zoological Society'


On 24 September, Stefan Lötters will be speaking at the 105th annual meeting of the 'Deutsche Zoologische Gesellschaft' (DZG) in Konstanz on "Ecological niches in Amazonian amphibians: linking macroecology and evolution", following a kind invitation by the 'Fachgruppe Ökologie'. 


Taylor & Francis Prize 2011 to Lötters et al.


Our molecular phylogeny on the critically endangered harlequin frogs (Atelopus) published in the journal Systematics and Biodiversity No 9 / 2011, was awarded the 'outstanding paper of the year' by the publisher.
