Fixed-term

The  Zoological Institute and Museum , Department of Animal Ecology, of the Faculty of Mathematics and Natural Sciences at the University of Greifswald, is seeking to fill a part-time position (65%) subject to funding approval, expected to start on September 1, 2026 , for a fixed term of 3 years . research assistant The position is to be filled. Remuneration is based on pay grade 13 TV-L Wissenschaft (Collective Agreement for Public Service Employees in the State of Hesse, Academic Staff). In this context, we are investigating how nutrient availability affects the development and effectiveness of defense mechanisms in water fleas – a crucial aspect for better understanding the complex interactions in the food web of freshwater ecosystems. Nutrients are transferred from primary producers to higher trophic levels, while predation is one of the main drivers of natural selection. In response to predation, many prey animals have evolved defense mechanisms that reduce its effects. To gain a more comprehensive understanding of how prey animals suffer from nutrient deprivation, we will examine the influence of nutrient availability on the expression of defense mechanisms in cladocerans (water fleas) of the genus Daphnia . Daphnia play a vital role in the transfer of essential nutrients from primary producers to higher trophic levels in freshwater ecosystems and represent a well-established model system for studying predator-prey interactions and nutritional ecology. In this project, we investigate the influence of food quantity and quality on the expression of inducible defense mechanisms using established predator-prey systems. The project is being conducted in collaboration with the research group of Christian Laforsch at the University of Bayreuth and Dominik Martin-Creuzburg at the Research Station for Aquatic Ecology in Bad Saarow of the Brandenburg University of Technology Cottbus-Senftenberg. As part of this project, a second position is available at the University of Bayreuth. This second position will work closely with the one advertised here. We will investigate how the availability of carbon and essential lipids affects the expression of defense mechanisms and resource distribution in Daphnia. By examining these changes and assessing the nutritional costs of inducible defense mechanisms, we will gain a better mechanistic understanding of how inducible defense mechanisms in Daphnia are influenced by the phytoplankton community, how nutrient deficiencies can limit the expression of defense mechanisms, and how this affects ecosystem stability.  The position offers the opportunity to link a doctoral thesis to the work area using the results generated in the project.
