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, as well as species' geographic range genesis,
   - 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.

Alarming Research Results: Dramatic Threat by New Salamander Fungus

31/10/2014

A novel skin-eating fungal disease discovered in Europe poses a major threat to native salamanders and newts.
Batrachochytrium salamandrivorans (Bs) was discovered only in 2013 by researchers investigating a remarkable decline in Fire salamander populations in the Netherlands.

New research, involving a global screening of more than 5,000 amphibians (under the lead of An Martel and Frank Pasmans from Gent University, Belgium, involving members from our group), now suggests that the new disease presents a serious threat to many species. Bs is very dangerous to most salamanders and newts, but not to frogs, toads and the snake-like amphibians called caecilians. The fungus was also found in newts from Thailand, Vietnam and Japan as early as 1894, without causing disease, suggesting Bs originates from Southeast Asia. Read more in a press release by Trier University (in German) or watch our movie (in German).

Apparently, Bs has arrived in Europe only recently so far the disease has only been found in the Netherlands and Belgium, but it is likely to reach other European countries soon. In 2014, our group has started a Bs and salamander / newt population monitoring and research program in the area in Germany close to the Belgian and Dutch outbreaks. This will be continued into 2015 and on.

01/02/2013

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.
