CURRENT PROJECTS

Clonality in Arnica montana L. (Asteraceae)

Throughout the species' range, wild populations of the well-known medicinal plant Arnica montana (montain arnica) are considered to be under threat. At the same time, it is unclear which role the plants' capability to reproduce vegetatively (clonality) has in maintaining the remaining populations. We test different approaches to meassure the frequency of clonality in mountain arnica populations based on genetic data.

Phylogeography of the threatened plant species Scabiosa canescens WALDST. & KIT. (Caprifoliaceae/Dipsacoideae)

Scabiosa canescens is a central European species of xerotherm habitats and considered thratened throughout Germany. Based on Chloroplast haplotypes we reconstruct the history of this plant's distribution to provide new insights for its protection.

Partial asexuality and the speed of adapation

The time a population needs for adapting to new environmental conditions is influenced by its reproductive system. While sexual reproduction (random mating) quickly produces new genotypes, asexual (clonal) propagation may serve to keep optimised genotypes. Based on a mathematical model (Markov chain), we study under which selective conditions a combination of sexual and asexual reproduction may lead to faster adaptation.

COMPLETED PROJECTS

Genetic diversity in hemisexual dogroses

Polyploid dogroses, Rosa canina agg., possess a unique reproductive system: due to a special form of meiosis, two genomes are transmitted as in a sexual diploid, whereas all others are passed on clonally. We analysed a Europe-wide microsatellite dataset to find sets of co-inherited alleles, which could hint at the evolutionary origin of different dogrose lineages.

Conservation and Digitization of Herbaria

Herbaria not just demonstrate the diversity of plants, but also document their fate through the last centuries. Again using Arnica montana as an example, we are investigating which data relevant for conservation can be gathered from digitized herbarium vouchers.

Genetic diversity of the rare desert shrub Calligonum bakuense LITV. (Polygonaceae)

With only about 150 individuals worldwide, Calligonum bakuense, a desert shrub endemic to coastal sand dunes near the Azerbaijanian capital Baku, is one of the rarest plants on earth. We use nuclear microsatellites to meassure its genetic diversity and contribute to its conservation.
