The Professorship of Forest Genetics seeks to hire a *Doctoral Researcher * * Deadline for application: 20. Januar 2026 * Start date: 1. April 2026 * Part-time position (65 %, usual conditions for PhD contracts in Germany) The position is embedded in the project "*BeGenDiv - A multispecies genetic diversity survey for the Biodiversity Exploratories*" and will focus on characterizing the genetic diversity of tree and shrub species in the forest plots of the Biodiversity Exploratories (https://www.biodiversity-exploratories.de/en/). The PhD project will investigate the genetic diversity of around 30 tree and shrub species in landscapes characterized by diverse combinations of forest management intensity and environmental heterogeneity. The PhD project will focus on a comparative analysis among species, while multi-species indices will be developed by a postdoctoral researcher in the same project. This is a collaborative project involving researchers from the University of Freiburg (Prof. Dr. Katrin Heer & Dr. Jill Sekely), the University of Marburg (Prof. Dr. Lars Opgenoorth), and UFZ Halle (Dr. Walter Durka).
