Who are the pioneers on a fresh moraine? Predators like certain carabid beetles, spiders and Opiliones are present almost immediately, before any vegetation occurs. It is a paradox that predators are first. May be they eat springtails, which are also pioneers. Among plants, small moss colonies are typical pioneers.

Glacier forelands are excellent study sites for investigating primary succession. The end of the little Ice Age has been followed by a continuous glacial retreat, leaving spatially ordered moraine sequences of different ages. The rate and success of faunal succession on these moraines are influenced by a set of complex processes. The aim of my thesis is to characterize succession patterns of alpine carabid beetles in glacier forelands, and their possible responses to selected biotic and abiotic factors. This will be done by identifying carabid beetles retrieved from pitfall traps, and analyzing the species richness and composition of the different habitats according to the age of the moraines, topography and snow cover.

This project is investigating the reproductive response of Carabid beetles to changes in their environment's temperature. Some of these species have adapted to cold climates by slowing down their maturation and changing the timing of their reproduction. We now wish to know if these populations will be able to do the oposite in response to warming temperaters. The results may be used to make predictions about the implications of global warming on future distributions of these insects.
