Density dependence of symbiosis form and its implications for population and community dynamics.

Join us to study the density dependence of symbiosis form and its impact on population dynamics in the Collaborative Research Unit DynaSym. We aim to use experimental and modeling approaches to test and develop basic concepts of density dependence of symbiosis form (e.g., shift from predator-prey to mutualistic interaction and back).

Postdoc position: This project will synthesize work from the literature and from other projects within the DynaSym Collaborative Research Unit and to develop general insights into the density dependence of symbiosis form and potential feedback dynamics between symbiosis form and density. As part of the synthesis work, the position holder will scientifically organize and lead workshops with other members of the research unit (administrative support for the organization is available). Highly motivated candidates with a Ph.D. in ecology, evolutionary biology, and related fields with experience in modelling and synthesis are strongly encouraged to apply. Candidates should demonstrate an enthusiasm for basic research and the ability to communicate effectively with individuals from a wide range of disciplines. The position is available for 48 months.

The Research Unit DynaSym has recently been funded by the German Research Foundation DFG (https://www.uni-konstanz.de/en/university/news-and-media/current-announcements/news-in-detail/mal-freund-mal-feind/) and is a collaborative initiative bringing together research groups from across Germany and international collaborators. 8 projects will collaborate within the research unit and cover experimental work with plankton systems, modeling, theory development and synthesis work. Workshops, retreats and research visits to other research groups are planned for all participants to facilitate exchange and additional training.

Konstanz is a very beautiful and pleasant place to live, bordering the third largest lake in Central Europe and situated near the Alps. As an equal opportunities employer, we welcome applicants from all sections of the community regardless of age, gender, gender identity, ethnicity, disability and sexual orientation. Interested candidates should send a CV, a short cover letter highlighting interests and potential research questions, and the contact details of two professional referees to lutz.becks@uni-konstanz.de. For more information see https://www.limnologie.uni-konstanz.de/becks/ or send email to Lutz. Review of applications will begin immediately and will continue until the position is filled.

Intragenotypic variation

An exciting opportunity to join a diverse research group working at the interface of ecology and evolution. The successful candidate will be part of an interdisciplinary team of researchers investigating the role of intergenotypic variation in the evolutionary and ecological dynamics of species interactions.

This project, funded by the Volkswagen Foundation, investigates individual variation independent of genotype and environment and how this variation can contribute to ecological and evolutionary dynamics. Using single cell approaches for eukaryoptic unicellular organisms, we aim to show when the combined intergenotypic variation of two interacting individuals hinders or facilitates rapid evolution and thus the overlap of ecological and evolutionary timescales.

Position 1 (36 months): The main responsibilities of this position include single cell assays to describe intragenotypic variation and estimate fitness consequences in green algae and other unicellular eukaryotes using high throughput imaging approaches and molecular tools. The position holder will also perform short term experiments to study the fitness consequences of intergenotypic variation of two interacting individuals and conduct experimental evolution. The successful candidate will have a Ph.D. or equivalent in evolutionary biology and extensive experience working with single cells and phytoplankton.

Post 2 (24 months): The main responsibilities of this position will include single cell transcriptomics and the development of genetic markers to describe intragrenotypic variation in green algae (and potentially other unicellular eukaryotes). The candidate will have a PhD or equivalent in molecular biology, extensive knowledge of sequence analysis and single cell work, and some background in phytoplankton work.

Evolution of endosymbiosis

We are looking for a highly motivated and enthusiastic postdoctoral researcher to work on the evolution of endosymbiosis. Join a diverse research group working at the interface of ecology and evolution on a project to study the evolutionary process and ecological conditions favoring the evolution of endosymbiosis. We are looking for a highly motivated scientist who will work with us to gain new insights into the biologically relevant conditions, evolutionary pathways and mechanisms that lead to the evolution of obligate endosymbiotic interactions. The project aims to develop theoretical insights based on observations from experimental work in the group and to contribute to the design of future experiments.

Highly motivated candidates with a PhD in evolutionary theory, mathematical modelling or theoretical biology are encouraged to apply. Previous work in the context of evolutionary transitions, the evolution of symbioses or species interactions is an advantage. Candidates should demonstrate an enthusiasm for basic research and an interest in mechanistic and phenomenological modelling. The successful candidate should be able to communicate effectively with people from a wide range of disciplines. The position is available immediately and will run until March 2027.
