Research interests

Over the last 20 years or so, we are witnessing a conceptual revolution in the field of population biology and ecological modeling, which was stimulated by the rapid development of advanced new scientific tools such and individual-based, spatially explicit population models, and Geographic Information Systems (GIS). There is much work to be done in developing our understanding of the new "spatial ecology", and my research program is driven by an interest in this topic. My primary research goals are (1) to broaden the theory of population and community to encompass an explicit consideration of spatially distributed processes, and (2) to develop methods to adapt simulation models optimally for ecological applications. To approach these goals I use several complementary approaches

My study systems include plant communities such as tropical forests in Sri Lanka and Panama, treeline dynamics in Europe, semiarid shrubland and grasslands in South Africa, the Patagonian steppe in Argentina as well as endangered animal species such as brown bears (Ursus arctos), Iberian lynx (Lynx pardinus), European lynx (Lynx lynx), and tiger (Panthera tigris).

Currently most of my time is absorbed by the ERC advanced grant project SPATIODIVERSITY that aims to understand the relative importance of processes and factors that govern the composition and dynamics of species-rich communities. Surprisingly, although most processes which are thought to contribute to species coexistence have a strong spatial component, the rich source of information on spatial patterns has only rarely been used for this purpose. We adopt a spatially explicit perspective and proceed in three steps:

  1. we quantify the highly complex spatial structures found in forests using recent techniques of spatial pattern analysis,

  2. we build a range of individual-based spatially-explicit simulation models ranging from “pure” neutral models to detailed process-based models of tropical forest, and

  3. we confront these simulation models with the set of patterns identified in (1) to identify the most parsimonious models that account simultaneously for all (spatial) patterns.
