We are seeking a PhD candidate to work on Evidence synthesis on individual niche spezialization. [pdf, 379 kb] de Please apply if you are interested.
Furthermore, we are seeking student helper with experience in data handling/management to support a practical course in September/October. Please contact Holger if you are interested.
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.
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.
