Current research
My main field of research is population ecology involving quantitative aspects like population dynamics (changes in population sizes and distributions over time), predator-prey interactions, biological control of pests, metapopulations, and reproductive strategies. The role of spatial processes, including local extinctions, dispersal and colonisations, has been one of my favourite research topics. Experimentally, I work with spider mites and predatory mites with the purpose of testing simulation models of predator-prey dynamics against empirical data. Recently, I conducted field in Greenland with purpose of studying adaptations of the seed bug Nysius groenlandicus to environmental conditions. As a spin-off of my interest in spatial dynamics, I have developed various statistical methods to obtain reliable estimates of population abundance with minimum sampling effort. After my retirement November 2012, I have worked together with Henrik Skovgård, University of Århus, on modeling biological control of stable flies by means of parasitoids. The project is financed by the Danish Ministry of Environment
