Martin Schroeder
Martin Schroeder is Professor of Forest Entomology at the Department of Ecology. Current research mainly concerns the ecology and population dynamics of the spruce bark beetle (Ips typographus). Other research interests are invasive forest insects and conservation of beetles dependent on dead wood.

Presentation

My research mainly concerns the following areas:

  • ­ drivers of the population dynamics of the spruce bark beetle
  • ­ key factors influencing biological invasions
  • ­ ecological risks with introduced tree species

The aim of my research is to develop sustainable and cost-efficient methods to reduce the risk for forest damages caused by insect pests. Some questions addressed for the spruce bark beetle are: (i) How much storm-felled spruce trees can be retained in the forest after a storms without risking initiation of large scale outbreaks? (ii) How do population dynamics differ between southern and northern Sweden? (iii) Will climate change influence the risk for damages? For invasive species importance of propagule pressure (i.e. number of arriving individuals) and habitat configuration for probability of establishment are studied. For introduced tree species the risk for damages caused by native bark beetles and the value of dead wood of introduced tree species for the biodiversity of beetles and fungi are studied.
