Bárbara Díez Rodríguez

Bárbara is working on the subproject “Natural DNA methylation variation in clonal and outcrossing European Populus nigra populations” in EpiDiverse since April 2018. In spring 2018, we planted a common garden with accessions of the clonal P. nigra italica from all over Europa, which we have epigenotyped using WGBS and phenotyped in the last two years.  Data analysis is now ongoing. Barbara is jointly supervised by Lars Opgenoorth and myself, and we closely collaborate with several groups in EpiDiverse – for example, Koen Verhoeven and Cristian Peña (NIOO Wageningen), and Oliver Bossdorf and Dario Galanti (EKUT).

Sarina Thiel

Sarina is working on the DFG funded project on “Vertical stratification of plant-animal interactions and their impact on pollination and seed dispersal within a single Neotropical plant species” since June 2018. Collection of field data took place at the Estacíon Bíologica Quebrada Blanco in the Peruvian Amazon from August – December 2018 and 2019. Currently, Sarina is genotyping adults and seedlings in our lab and is analyzing the interaction data. The project is carried out in collaboration with Eckhard Heymann (DPZ Göttingen and Marco Tschapka (Universität Ulm).

Jill Sekely

Jill investigates local adaptation of Nothofagus pumilio along the latitudinal gradient in the Andes in Argentina. She started her PhD in January 2019 and is jointly supervised by Lars Opgenoorth and myself. The project is carried out in collaboration with colleagues from INTA Bariloche and is funded by the DFG. Fieldwork took place from January – April 2019 and 2020. Recently, we have received the SNP data which we generated by targeted sequencing of ~ 800 genes and data analysis is ongoing.

Melanie Zacharias

Melanie investigates local adaptation of Picea glauca at the University of Greifswald, and will carry out the analysis of genetic data under my co-supervision.
