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

FIToM - "From Individuals to Metapopulations": A collection of projects used for teaching and research purposes in population ecology. Download the zipped file to your desktop and click on the Fitom.exe icon. The program will be installed in a subdirectory under "Program files" called "Fitom". The executable file is called Fitom.exe. A short-cut to Fitom.exe should be available on your desktop.

Before you use the program, contact me ( to receive the newest version of the manuals to help you running the program. The written material consists of exercises in various biology courses based on Fitom. You are also welcome to contact me in case you are interested in models not described in the manuals

Sampling.pdf is lecture notes on sampling methods of insects and mites.
