Plant population ecology group

Grasland

Welcome to our research group! We are plant population and community ecologists interested in a broad range of topics, including the importance of micro-evolutionary processes for ecological dynamics, and the role of ecological interactions for species coexistence and the functioning of terrestrial ecosystems. We are particularly interested in how anthropogenic drivers like land management, climate change, or invasions by exotic species influence micro-evolutionary processes and species interactions. To study these processes, we use manipulative experiments in the greenhouse, in the common garden, on experimental fields and even in real ecosystems, and employ quasi-experimental approaches that make use of existing environmental gradients across landscapes.

In my PhD project I focus on the consequences of climate change on ecosystem processes in different grassland types. At the Global Change Experimental Facility (GCEF) I study plant productivity and diversity under realistic land-management conditions, both with ambient climate and changed climate conditions according to future scenarios. To assess the effects of an extreme drought on grasslands we set up an experimental site as part of the International Drought Experiment (Drought-Net) by using fixed shelters. On this site I also collect data about productivity and plant community composition. By the use of common research protocols the results will be comparable to over 60 sites worldwide.

My PhD project is about the importance of antagonistic interactions on plant species coexistence and ecosystem functioning. I focus on how pathogens and herbivores act to maintain species diversity in grassland ecosystems and how invasion by exotic species impacts this relationship. To answer these questions I established a field experiment that includes native and exotic plants sown at different frequencies and exclusion of antagonists by pesticide application. Greenhouse experiments to study trade-offs between competitive ability and defense of plant species, as well as molecular analyses to identify fungal species will complement my findings in the field.

My PhD research focuses on the processes that lead to naturalization of an invasive plant (Ageratina adenophora) along an elevational gradient in western Himalaya. Specifically, I am working on the local adaptation and phenotypic plasticity of the invasive plant using reciprocal transplant experiments along the elevational gradient. My research is supported by DAAD (German Academic Exchange Service).

Reproductive and establishment traits of annual plants in river corridors. A comparative analysis of co-occurring alien and native species.
The objective of this study is to test whether invasive and native species co-occurring in riparian habitats differ in ecologically relevant traits. We have compared traits between congeneric invasive-native species pairs in controlled competition levels and co-occurring in riparian habitats, as well between alien and native elements of existing riparian plant communities.
