Fedtschenkoi's Bush-cricket (Roeseliana fedtschenkoi)

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

March: The 5th international SQuID workshop (statistical quantification of individual differences) is taking place in Sapporo, Japan.

March: Our annual Bachelor practical Evolutionary Biology is running in the first two weeks of March. We use simulation tools to teach students basic concepts of population genetics in a highly interactive way. As every year, it is great fun.

February: We have begun to plan this years MEES Master de student excursion to southern Spain. The excursion will focus on animal migration, birds in particular.

January: It seems we have made a big step towards understanding the genetic basis of the green-brown polymorphism in Chorthippus grasshoppers. Replicated differential expression analysis was produced robust results.

January: Anne and Max are attending an sDiv workshopExternal link sCONSUME. It is an international workshop that brings together early-career scientistcs from different disciplines. A great experience.

January: Elio and Benjamin have joined our group as two sDivExternal link funded postdocs. Elio will work on karyotype, genome size and sperm diversity of grasshoppers. And Benjamin will use variance decomposition approaches to model the role of species turnover on herbivore biomass. Welcome, Elio! Welcome, Benjamin

    Sting Bug (Antheminia varicornis)

    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 ExperimentExternal link that was established in 2002 and has been DFG-funded since then. More recently, we got engaged in a NC3 Collaborative Research CenterExternal link 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)External link in Halle-Jena-Leipzig, the Michael Stifel Center Jena (MSCJ)External link for Data-Driven & Simulation Science and the Interantional Max Planck Research School (IMPRS)External link 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)External link 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.

    Fieldwork with students

    Image: Günter Köhler

    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.
