Dr. Sascha Liepelt


Research interests:

I am interested in spatio-temporal genetic patterns within and among plant populations and what we can learn from them with respect to key evolutionary processes. Within this framework my main research focus is on forest trees.

By better understanding the evolutionary dynamics of forest tree species I want to contribute to objective, science-based decisions in conservation and forest management.

In my research I have developed and used a wide range of molecular markers from all three genomes (nucleus, mitochondria, chloroplasts) as tools for reconstructing processes from phylogeography to adaptation.

Range-wide spatial patterns often depict processes at the time-scale of glacial cycles and can be detected with organelle DNA markers. The processes involved are e.g. expansions and contractions of the distribution range or long-term isolation of refugia. One of my main interests is the study of the postglacial history of the European silver fir, Abies alba, and closely related fir species from the Mediterranean region to understand processes of isolation, hybridization and introgression within and among species. Currently I am also involved in the reconstruction of the phylogeography of the European larch (Larix decidua).

On the local scale processes like pollen or seed dispersal are crucial for the dynamics of ecosystems. Here, highly polymorphic molecular markers are necessary to track the offspring of parent trees in space and time with the help of so called DNA fingerprints. My research on this scale is about seed dispersal in A. alba and Fagus sylvatica (beech) and clonal structures and gene flow in the floodplain plant Cnidium dubium.

Single nucleotide polymorphisms within candidate genes are the markers of choice for the study of selective processes along ecological gradients or on a range-wide scale. Using such markers developed by next generation sequencing technology my next goal is to gain insights into selective processes within A. alba driven by environmental heterogeneity along local ecological gradients.

Some of the tools I developed for molecular-ecological research are also useful for identification and control purposes in nature conservation, forestry and forensics.
