Welcome to the Population Ecology Group

We are interested in eco-evolutionary processes and how they contribute to the evolution and maintenance of biodiversity. Our special focus lies on local adaptation and the role of species interactions. We approach this topic from different angles, including long-term experimental field work, controlled laboratory experiments, and genomic analyses.

Recent news

September: Yuanyuan has started her work as a data curator for the Jena Experiment. She will work very closely with members of the current Research Unit FOR 5000. Welcome, Yuanyuan!

September: Holger is serving for this year's panel Natural and Engineering Sciences of the Swedish Research Council for grant evaluation.

August: A new paper on the ecological realism of biodiversity experiments for understanding the consequences of biodiversity loss was published in Nature in Ecology and Evolution and is featured in a press release de.

August: Reto is unfortunately leaving for the group. He has established the wheatear complex as a model for studying speciation and hybridization, work that is to be continued. We wish you all the best for the future, Reto!

July: Dave got awarded a AFR grant by the Fonds National de la Recherche Luxemburg (FNR). The grant will cover his PhD project. Great news and congratulations, Dave.

July: Our Collaborative Research Center is holding an online workshop on eco-evo meachnisms with an brilliant list of speakers. The workshop is covering the interface between biology and philosophy.

June: Elina got elected for the PhD representative council of Jena University. The council is advising the senate and recotorate on matters concerning PhD students. Congratulations, Elina!

June: Our paper on systematic heterogenization is out in Nature Reviews Neuroscience. Check out our ideas to increase reproducibility and generalizability by incorporating biological variation in experimental design.

Our group covers three main lines of research, all united by the interest in understanding population-level biodiversity and its consequences for intra- und inter-species population dynamics. (i) trophic interactions and community dynamisc are the focus of Community Population Ecology line of research. (ii) Local adaptation, temporal population dynamics and behavioural ecology are the focus of Evolutionary Population Ecology line of resaerch. (iii) And the genomic architecture of genetic polymorphisms, speciation and hybridization are the focus of Molecular Population Ecology line of resarch. Furthermore, we are interested in (iv) ecological, evolutionary and startistical methods and therefore also cover the field that we call Population Ecology Methods.

Contemporary scientific work is often very collaborative. We are therefore involved in several large collaborative research project. This includes the long-running Jena Experiment that was established in 2002 and has been DFG-funded since then. More recently, we got engaged in a Collaborative Reserach Center (SFB-TRR 212) that is also funded by the DFG and studies the evolutionary ecology of individualized niches. Furthermore, we are participating in the German Centre for Integrative Biodiversity Research (iDiv) in Halle-Jena-Leipzig, the Michael Stifel Center Jena (MSCJ) for Data-Driven & Simulation Science and the Interantional Max Planck Research School (IMPRS) run by Max Planck Institute for Chemical Ecology in Jena. Additionally, we are involved in more grass-roots projects such as the Nutrient Network (NutNet) and the team for the Statistical Quantification of Individual Differences (SQuID). And finally, there are always ongoing individually funded projects that are also important.

We are a team of currently six postdoctal researchers, three PhD students, five technical assistants, and four gardeners. We will occasionally solicit applications for funded PhD student positions. Furthermore, if you are interested in joining the group with external funding or as part of your studies, you may contact us at popecol@uni-jena.de.

Teaching Show content

We offer a variety of classes for the BSc level in Biology and the MSc level in Ecology, Evolution and Systematics. The topics range from introduction to faunistic field methods, evolutionary, community and conservation ecology, via population genetics to scientific writing and presentations. We also continously offer a selection of topics for Bachelor or Master projects. The list of ongoing and completed projects gives an impression about the range of topcis that we offer. Please to not hesitate to contact us if you are interested and movitated to work in the field of evolutiony, molecular or community ecology.
