RTG 2300: Enrichment of European beech forests with conifers

Jonas Glatthorn

(Postdoctoral researcher in EnriCo 2017-2022)

Curriculum vitae

Jonas Glatthorn completed his B.Sc. in ‘International Forest Ecosystem Management’ at the ‘Eberswalde University for Sustainable Development’ and his M.Sc. in ‘Forest Sciences and Forest Ecology’ at the University of Göttingen. During his PhD-project at the department of ‘Plant Ecology and Ecosystems Research’ at the University of Göttingen he studied European beech forests in Slovakia focusing on differences between production and primeval forests regarding productivity, canopy structure and structural diversity. Jonas Glatthorn’s general research interests include topics such as ecosystem functioning of differently managed forests, the relationship between stand structural characteristics at different spatial scales and ecosystem processes and adaption of forest stands to climate change.

Research interests

  • Relationships between functional and structural composition of forests and ecosystem functioning
  • Natural dynamics of forest ecosystems
  • Structure and function of tree canopies

Research

In his research at EnriCo Jonas Glatthorn focusses on the synthesis of results in collaboration with all subprojects. Amongst other things, he is dealing with the conceptual ecological background of interdisciplinary research of forest ecosystems, the response of different species groups on enriching European beech forests with Douglas-fir and Norway spruce and the quantitative assessment of tree diversity at neighborhood-level.
