Malika Gottstein (doctoral researcher)
Malika will investigate the role of brown-headed spider monkeys as important seed dispersed in the Chocó region of Ecuador. She will specifically focus on the importance of primate seed dispersal for certain tree species that are of economic importance and selectively logged in the study area. She will study interplay of primate seed dispersal and selective logging on the generation and genetic diversity of these species. The project is co-supervised by Prof. Dr. Eckhard Heymann (DPZ) and Citlalli Morelos Juárez (Jocotoco).
Stefanie Hoeber (PostDoc)
Stefanie works in the Phenology project together with the PhD students Claudia and Alessandro and supports the teaching of the working group.
Sandra Link (Lab tech)
Sandra manages the lab of our working group – currently hard at work to set up our lab.
Alessandro Mainardi (doctoral researcher)
Alessandro is working on the DFG funded project “Phenology of tropical tree species – environmental cues, molecular mechanisms, and consequences for plant-animal interactions”. Data collection will take place for three consecutive years from February to July in the Estación Científica San Francisco, located in Southern Ecuador at 30 km from Loja. Phenology and Genetics data will be analyzed in the Molecular Biology laboratory in Freiburg.
Jill Sekely (doctoral researcher)
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.
Jessica Sun (Team assistant)
Jessica takes care of organizational matters in the working group.
Claudia Viganò (doctoral researcher)
Claudia is working on the DFG funded project “Phenology of tropical tree species – environmental cues, molecular mechanisms, and consequences for plant-animal interactions”. Data collection will take place for three consecutive years from July to December in the Estación Científica San Francisco, located in Southern Ecuador at 30 km from Loja. She will specifically focus on herbivory and pollination in the context of regular annual phenology of selected tree species.
Cristina Zamora (Postdoc)
Cristina investigates tree-pathogen interactions at the molecular level looking into gene expression of both interaction partners. She is also involved in several projects of the working, e.g. in gene expression analysis of tropical tree species and in the assessment of gene flow distances. For teaching, she mostly focuses on bioinformatics.
Dr. Bárbara Díez Rodríguez
Bárbara investigated DNA methylation variation in the clonal Populus nigra cv. italica EpiDiverse in 2018 – 2023. 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. Barbara was 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).
Dr. Melanie Zacharias
Melanie investigated local adaptation of Picea glauca at the University of Greifswald, and carried out the analysis of genetic data under my co-supervision. She will soon defend her thesis on local adaptation and plasticity of white spruce at tree line populations in Alaska
Dr. Sarina Thiel
Sarina completed her PhD in 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” . She collected data at the Estacíon Bíologica Quebrada Blanco in the Peruvian Amazon from August – December 2018 and 2019. The project is carried out in collaboration with Eckhard Heymann (DPZ Göttingen) and Marco Tschapka (Universität Ulm).
