Research interest

My research focuses on the question how species rich ecosystems differ from species poor systems in their properties and functioning. I am especially interested in plant animal interactions and try to understand the reciprocal effects between herbivores, their natural enemies, and plant diversity. More applied aspects of my research investigate how these interactions, and ecosystem functions in general, are altered by human activities like forest fragmentation, land-use, and species introductions.

Current Projects

The Jena Experiment (www.the-jena-experiment.de)
As synthesis post-doc of one of the largest Biodiversity Experiments, I analyze how plant diversity changes functions and properties ranging from abiotic conditions to species interactions, from above- to belowground, and from plants to top predators. These analyses are based on a large pool of data collected during the last 12 years by members of the research unit. In addition, I measure rates of herbivory and predation investigating their relationship to plant diversity and plant traits. These measurements are currently conducted within the doctoral thesis of Lionel Hertzog.

Rapid measurements of ecosystem functions
Quantifying ecosystem functioning is important for both fundamental and applied ecological research. However, there is currently a gap between the data available and the data needed to address topical questions, such as the drivers of functioning in different ecosystems under global change or the best management to sustain provisioning of ecosystem functions and services. To close the identified ecosystem functioning data gap, I research low-tech, easy to use, repeatable, and cost efficient methods than can be used to measure proxies of ecosystem functions. The collection of these methods for of important ecosystem functions I named Rapid Ecosystem Function Assessment (REFA). Using REFA enables standardized and comparable measurements of proxies for ecosystem functions on a large scale within and across studies. A review introducing REFA has been published in Trends in Ecology and Evolution.

Degradation of South Brazilian grasslands
Natural grasslands in south Brazil have at a large scale been converted into tree plantations or agricultural land or been severely degraded. This project, which is a cooperation between the groups for restoration ecology and terrestrial ecology at TUM, investigates the biotic composition and the ability to perform ecosystem functions at grassland sites spanning a degradation gradient. In addition, the potential of these sites for ecological restoration and suitable techniques are assessed.

The invasive plant species Tansy and Goldenrod in a cross-continent competition experiment
While Goldenrod is invasive in Europe and hypothesized to suppress native Tansy, Tansy is invasive in North America, potentially replacing Goldenrod. This doctorate project by Nafiseh Nahdavi investigates in cooperation with Ray Callaway (University of Montana) the competitive interactions between the two plants in field experiments on both continents and additional greenhouse experiments. A focus of the project is the role played by herbivores for the competitive outcome in native and introduced ranges.
