Biodiversity
In truth, biodiversity is not really a single research topic, but rather an overarching theme guiding a large part of my research. In this theme, we develop models and data analysis tools to study patterns biodiversity in various systems.
Current research topics are:
-
Resource competition
-
Networks on Networks: The interplay of structure and dynamics in spatial ecological network. This is funded as subproject 1 in DFG Research Unit 1748.
-
Cell shapes of marine plankton
-
Indices of biodiversity
-
Optimal control of spatial ecosystems

Professor for Mathematical Modelling
I am interested in the theoretical description of complex living systems at the interface of theoretical ecology and applied mathematics

Estimation of functional diversity and species traits from ecological monitoring data
The rampant loss of biodiversity is starting to be recognized as a global crisis rivaling the climate emergency. To address this …
Coexistence patterns and diversity in a trait-based metacommunity on an environmental gradient
The dynamics of trait-based metacommunities have attracted much attention, but not much is known about how dispersal and spatial …
Functional trait dimensions of trophic metacommunities
Metacommunity ecology currently lacks a consistent functional trait perspective across trophic levels. To foster new cross-taxa …
Optimal Planting Distance in a Simple Model of Habitat Restoration With an Allee Effect
Ecological restoration is emerging as an important strategy to improve the recovery of degraded lands and to combat habitat and …
Optimal stock–enhancement of a spatially distributed renewable resource
We study the economic management of a renewable resource, the stock of which is spatially distributed and moves over a discrete or …
Shape matters: the relationship between cell geometry and diversity in phytoplankton
We analyse data on marine unicellular phytoplankton, exhibiting an astounding diversity of cell sizes and shapes. We quantify the …
Modern models of trophic meta-communities
Dispersal and foodweb dynamics have long been studied in separate models. However, over the past decades, it has become abundantly …
Mid-domain effect for food chain length in a colonization-extinction model
The mid-domain effect states that in a spatially bounded domain species richness tends to decrease from the center towards the …
Long-term cyclic persistence in an experimental predator–prey system
Predator–prey cycles rank among the most fundamental concepts in ecology, are predicted by the simplest ecological models and enable, …
Biodiversity change is uncoupled from species richness trends: Consequences for conservation and monitoring
- Global concern about human impact on biological diversity has triggered an intense research agenda on drivers and consequences of …
Unifying ecological stoichiometry and metabolic theory to predict production and trophic transfer in a marine planktonic food web
Two ecological frameworks have been used to explain multitrophic interactions, but rarely in combination: (i) ecological stoichiometry …
A new dimension: Evolutionary food web dynamics in two dimensional trait space
Species within a habitat are not uniformly distributed. However this aspect of community structure, which is fundamental to many …
Emergence of evolutionary cycles in size-structured food webs
The interplay of population dynamics and evolution within ecological communities has been of long-standing interest for ecologists and …
Environmental and trait variability constrain community structure and the biodiversity‐productivity relationship
There is still considerable debate about which mechanisms drive the relationship between biodiversity and ecosystem function (BEF). …
Evolutionary food web models: effects of an additional resource
Many empirical food webs contain multiple resources, which can lead to the emergence of sub-communities—partitions—in a food web that …
