What are the effects of foreign genotypes in new habitats?

In road side construction, replantation of habitat specific species is common practice. However, as result of cost savings, the seeds most often are of foreign origin and hence represent foreign genotypes. In the course of this project we investigate the influence of foreign genotypes upon native gene pools. Hereby we investigate, if native genotypes are better adapted to native ecological niches and therefore are fitter and genetically more diverse than foreign progenities, if both geenpools hybridize, or one displaces the other – hence is fitter and reproductively more successful.

The project is supported by the Deutschen Bundesstiftung Umwelt (DBU) abd the Heidehofstiftung.
