Studies on the lesser burnet (Pimpinella saxifraga)
In a population genetic comparison of 1. reclamation of roadsides with non-native seeds and 2. plant diversity of the same species in nearby nature reserves, we investigated whether genetic diversity differs (funded by DBU and Heidehofstiftung). This revealed that two different genotypes coexist in the case of the lesser burnet. Through population genetic analyses, we are now trying to analyze the genetic diversity of the lesser burnet throughout its range to reconstruct whether genetic barriers and local adaptations are responsible for this phenomenon.
