Overview of research projects

A central theme in my research is the diversity of life on earth ("biodiversity"). In particular, I am interested in the effects of changes in biodiversity on ecosystem processes such as plant-insect interactions and herbivory, and how biodiversity loss can be counteracted.

In addition, I am studying anthropogenic environmental changes (climate and habitat changes) in a variety of ecosystems such as grassland, arable land/cropland, heathland, beech forests, and peat bog ecosystems.

In particular, theory-based smaller-scale experiments and applications in nature conservation on a landscape scale are combined.

Research on grassland biodiversity

MSc student: Niklas Krummel; PhD student: Julia Tiede

We are currently setting up a new small-scale grassland biodiversity experiment in Göttingen. This research complements approaches used within the framework of the Jena Experiment, a large long-term biodiversity experiment (see below).

The Jena Experiment

Within a large and long-term biodiversity experiment, we study:

(1) How plant diversity affects the diet of carnivores, herbivores and omnivores
(2) Effects of plant diversity on flower traits and pollination along an experimental plant diversity gradient

At current, this involves the use of next-generation DNA sequencing approaches (pyrosequencing) to study how the diets of omnivorous Carabid beetles changes with plant diversity, plant species identity and plant traits. For this purpose, we collaborate with the research groups of Michael Traugott (Innsbruck) and Rolf Daniel (Göttingen).

In addition, we plan to study plant-seed predator and continue to study plant-pollinator interaction networks, with a focus on spatiotemporal niche differentiation.

Past research (2003-2010) has focused on multitrophic responses as a function of plant species richness.

Biodiversity positively affects ecosystem services

A particularly interesting finding is that plant species richness positively affects ecosystem services important for human well-being. These services include:

  • weed suppression and invasion resistance
  • decomposition
  • parasitism and biological control
  • flower visitation and pollination
  • resistance against plant pathogenic fungi

Plants form the basis of terrestrial food webs

Our research has shown that changes in plant biodiversity affects above- and belowground trophic interactions, with effects dampening the higher you climb the "trophic ladder".

The Jena Experiment is a multidisciplinary, long-term research facility to study the effects of changes in plant species richness on ecosystem processes. For example, we are interested in the effects of plant species richness on processes at higher trophic levels. One central research question during the last years has been: Are plant monocultures more susceptible to herbivore attack than plant mixtures?

Effects of hedgerows on crop yield

BSc student: Nina Bacchi

Within the framework of a BSc thesis, we measure effects of different types of field margins on yield of crops (oilseed rape, wheat). We test the hypothesis that field margin type influences yield, e.g. via enhanced biological control or altered microclimate.

In contrast to previous studies, we harvest whole plants and collect seeds using threshing machines and seed cleaning machinery. This will give insights into yield components that are relevant from a farmer´s perspective.

A grid-based sampling approach for landscape-wide biodiversity

We have developed new approaches to study lanscape-wide changes in biodiversity of different organism groups. Using replicated landscapes, we show that biodiversity dynamics in space and time can best be understood when all available habitats are sampled (rather than focusing just on managed or seminatural areas).

Image classification mapSampling grid for one 1x1-km landscape

Image recognition software
(ENVI EX) was used for landscape-wide habitat classification based on false-colour infrared images from the RapidEye satellite. In each of 10 landscapes (size 1x1 km), we then established regular sampling grids with 25 sampling locations. At each sampling location, we measured parameters such as vegetation composition, herbivorous beetle abundance and pollinator abundance.

Measuring landscape context using grid sampling rather than concentric circles

Traditionally, landscape context has been measured using a "concentric circles" approach. Such an approach is inadequate in many cases. A grid-based sampling, shown on the right, allows sampling all habitats occurring in a landscape (modified from Scherber et al. 2012)



Research on butterflies, plants and leafhopper communities in calcareous grasslands

In collaboration with the Naturpark Meißner-Kaufunger Wald, we study plants, butterflies and leafhopper communities and how they are affected by land-use intensity. Using transect approaches, we study gradients ranging from the centre of each calcareous grassland out into other surrounding habitat types.

Spatiotemporal changes in landscape patterns and biodiversity

Using remote sensing data (RapidEye satellite), we study changes in landscape structure over time. We combine this approach to trace organism abundance and species number through space and time.

Scale effects in biodiversity and biological control: methods and statistical analysis

Within the DFG-funded Research Training Group, we focus on two major questions:

(1) Scale dependence of plant-insect interactions and community structure in changing landscapes

Spatial processes play an important role in community and population ecology. For example, the immigration of individuals from different habitats in the surrounding landscape can be important for local community composition, a process that is termed mass effect. In addition, community composition may change across different spatial scales. This can have far-reaching implications for ecosystem services. For example, the effects of local complexity on local pollinator communities may be both high or low, depending on spatial scale (scale- and context-dependence). While previous studies of our group have shown that landscape context is an important determinant of biodiversity and ecosystem services, mechanistic insights into the underlying processes are lacking. In particular, the data collected so far do not allow explicit spatial modelling approaches, spatial interpolation, or the incorporation of spatial dependencies. In addition, data on dispersal rates of organisms are lacking so far. Here, we will study the scale-dependence of ecological communities in agricultural landscapes and organism interactions in the field. The description and the prediction of the intensity of a species, i.e., the abundance of organisms, will be based on the theory of random marked sets, a generalization of the theory of marked point processes.

1.1. Effects of landscape complexity and spatial scale on organism interactions We analyse dispersal, species richness, and abundance of focal organism groups using regular 1 × 1-ha grids positioned in 6 landscapes of different landscape complexity. At least 20 grid plots will be sampled per landscape. The identification of large quantities of invertebrates requires extensive expert support. GIS mapping and vegetation mapping will be central to explain the observed patterns and will serve as a basis for modelling. Vegetation leaf area index (LAI) and leaf nitrogen content will be predictors of vegetation density and attractiveness to herbivorous insects.

1.2. Dispersion of organisms in an agricultural landscape across different spatial scales We model the relationship between organism mobility, spatial landscape configuration and immigration in new habitat (mass effects), including Monte Carlo simulations.

(2) Scale and context mediated conservation management in fragmented landscapes and populations

Given a finite total area that can be set aside for conservation in human-dominated landscapes, what configuration would represent the best strategy? In contrast to prevailing arguments in favour of large habitats based on the classic theory of island biogeography, many small islands spread over a larger region may better capture a maximum of biodiversity. A sample of many reserves over a wider geographic range maximizes species richness, but in each of these small fragments, persistence of populations and ecological interactions are reduced. Reducing dispersal among habitats is similar to reducing gene flow to keep a maximum of breed diversity. In both cases, dissimilarity (of local communities or breeding populations) is conserved and thereby beta-diversity is maximized. This is in contrast to common views that, in order to maximize diversity, functional connectivity between spatially separated subpopulations should be increased, as this reduces probabilities of subpopulation extinction or allele loss. The outcome of conservation strategies is not trivial, as it depends on properties of the landscape (spatial configuration of fragments, and type of landscape matrix), species, and the resulting communities (food web interactions and ecosystem functioning). A systematic analysis of existing studies will be most valuable.

In addition, a spatially explicit multi-species model with stochastic birth, death, and dispersal processes is developed to analyse trade-offs between subpopulation persistence and beta-diversity for different landscape configurations and species groups. We will test the hypothesis that conservation value of population segregation and genetic exchange changes with fragmentation structure and scale.

We are interested in (i) developing a deeper theoretical understanding of the mechanisms using toy models and larger Monte Carlo studies; (ii) deriving optimal fragmentation strategies with respect to number and size of subpopulations and rate of geneflow between subunits that are relevant for animal conservation programs; (iii) field tests by repeated sampling (about 4) of several fragmentation levels (at least 10) in various landscapes (about 12), and model validation.

2.1. Conservation management in fragmented landscapes I An empirical test of the relative role of habitat area, fragmentation, and landscape matrix, using species differing in dispersal and specialisation has to be developed. Trapnesting bees and wasps, identified by extrenal experts, will serve as model systems to study fragmentation effects, supported by additional collections of organisms at different spatial scales.

2.2. Conservation management in fragmented landscapes II Development of spatially explicit models and analysis by means of Monte Carlo methods to clarify trade-offs in subpopulation persistence and beta-diversity.

2.3. Modelling of allele and haplotype dynamics in fragmented populations Here, theoretical optimisation of fragmentation patterns will be investigated. Genomic data of isolated chicken populations will be investigated.

4. Coexistence of species in populations with spatially structured interaction Analytical results on the parameter ranges will be obtained that allow for long term coexistence of species in interacting particle systems with different levels of local versus non-local competition.

Grassland Management and biodiversity

PhD student: Georg Everwand (2010-2013)
MSc student: Till Benner
BSc students: Melanie Wiechmann, Annabelle Rohlfing, Wiebke Röper

Agricultural intensification is known to greatly influence biodiversity and multitrophic interactions, but the relative contribution of plant functional groups, e.g. herbs and grasses, to biodiversity is less understood. In a multidisciplinary approach with botanists, soil ecologists and phytopathologists, we characterize insect responses to fertilization, mowing and plant functional group composition in a grassland experiment. Management and plant community effects will be characterized by insect samples, quantification of herbivory and experimental phytometer studies, addressing responses of pollinators, herbivores and predators.

The number of climate change drivers affects herbivore performance

Among the most surprising findings of our studies was that the number of climate change drivers affected herbivore performance. That is: In some ways it doesn´t matter if drought or warming kick in - it´s just how many drivers act simultaneously that matters. See an enhanced figure from our Ecology & Evolution paper:

Number of climate change drivers and herbivore performance



We show that insect herbivore performance (Lochmaea suturalis) is indirectly influenced by climate change via changes in plant quality, especially leaf tannin content and carbon-nitrogen ratio of Calluna vulgaris tissues.

Drought, warming and elevated CO2 effects in insect herbivore performance


Effects of climate change on above-belowground interactions

Experimental design for above-belowground climate change

In another experiment, we show that above-belowground interactions are modified by climate change under field conditions. Our study is among the first proving that herbivory-induced nutrient cycling can be altered by combined climate change drivers (drought, warming, elevated CO2).

Biodiversity Exploratories

PhD student: Christoph Rothenwöhrer (2008-2011)

The Biodiversity Exploratories are part of the international long-term ecological research (iLTER) network. In Germany, there are several such long-term ecological research projects. Within the framework of the Biodiversity Exploratories, we study ecosystem processes such as herbivory and pollination in selected grassland and woodland sites along land-use gradients.

Most importantly, we manipulated local-scale management by setting up electric fences to exclude grazing farm animals. We employed mowing treatments, and added phytometers crossed with complex predator exclusion treatments.

Peat Bog Ecosystems

Restoration of peatland and conservation of the Dwarf Birch (Betula nana)

MSc student: Barbara Mayer (2010)

Since May 2010, we are studying plant-herbivore interactions along a drought gradient in a peat bog in Southern Bavaria (close to the towns of Seeshaupt and Bernried). In particular, we study the performance of the dwarf birch, Betula nana L. (Betulaceae), which is a glacial relict species. We monitor bog water level and follow plant performance over time.

Some of Germany´s most extensive peat bog ecosystems occur throughout Southern Bavaria (Germany). These bogs are fascinating environments that have been formed gradually after the last glaciations (about 10,000 years before today). Situated at the foothills of the Alps, many of these peat bogs (locally called "Filz") belong to the most vulnerable ecosystems in Germany, inhabited by often highly adapted species that can cope with the low pH of soil and water. I am personally interested in dragonflies, butterflies and herbivorous insects inhabiting peat bogs, as well as carnivorous plants, grasses, sedges and rushes, and Sphagnum peat mosses.

Biological control and management of invasive alien plants

MSc student: Kerstin Albrecht (2011; University of Rostock)

Narrow-leaved ragwort is an invasive alien plant introduced to Europe with wool transports from South Africa about hundred years ago. It is currently rapidly spreading across Europe. In a research facility at Silwood Park (UK), we have installed an experiment on the effects of herbivory and competition on S. inaequidens. Although the main results of the establishment phase have been published, some plants have survived from 2002 until today and are still producing inflorescences even though growing in intact British grassland. It will be fascinating to see if and how this plant will survive and reproduce over long-term periods.

Hummingbird pollination

Collaboration with Oregon State University (Matthew Betts, Adam S. Hadley)
PhD student: Urs Kormann

Violet Sabrewing (Hummingbird)

Within the framework of the DFG research training group "Scaling Problems in Statistics" we are studying hummingbird pollination in tropical forests in Costa Rica (Las Cruces station). Using artificial feeders positioned along fencerows, we study connectivity and pollinator movement among rainforest fragments.

Gallery forest and Inselbergs in the Ivory Coast (West Africa)

(with S. Porembski, N. Biedinger and others, University of Rostock; Image credits: S.Porembski)

This was a short-term research stay in 2000, where we collected plant material and did vegetation relevés on inselbergs in the Ivory Coast. Among other plant species, we found the carnivorous plant species Genlisea stapfii, Utricularia subulata, Utricularia juncea and Utricularia pubescens (Lentibulariaceae) and Drosera indica (Droseraceae).
