A2.17: ASSESSING GENETIC DIVERSITY AND DIVERGENCE WITHIN AND AMONG POPULATIONS OF THE THREATENED PLANT CHASMANTHERA DEPENDENS (MENISPERMACEAE) IN WEST AFRICA

My research is focused on microevolutionary processes that provide and enable population and lineage diversification. I am specifically interested in interspecific hybridization and polyploidisation, mechanisms representing particularly important means of speciation in plants. I am also interested in differentiation and shift in reproductive modes of plants.

Current active research projects

• Drivers of evolution in Bromeliaceae
Within several projects dealing with the neotropical family Bromeliaceae, drivers and processes forming a vast diversity of this family are identified. My competence covers population genetic approaches as well as ploidy and genome size estimations.

• Evolutionary origin and speciation in agamospermic species complexes in the genus Potentilla
Hybridisation, often followed by polyploidisation or introgression, is an important mechanism in the speciation and evolution of higher plants. The genus Potentilla is used as a model system for studying these phenomena as it is morphologically extensively variable, exclusively polyploid and expresses apomixis.
(with T. Gregor, C. Dobeš)

• Phylogeography of Carpinus betulus and Carpinus orientalis with the focus on Carpathian and Balkan Mountains
Investigation of hornbeam species is very important due to a unique episode in the forest history in Europe defined by a hornbeam layer between oak and spruce forest. It is specific for Carpathian and Balkan Mountains and constitutes one of the regional differences between the postglacial vegetation history of Balkans and Western Europe.

• Assessing genetic diversity and divergence within and among populations of the threatened plant Chasmanthera dependens (Menispermaceae) in West Africa
This project aims at understanding the genetic variation and phylogeographic history of C. dependens populations in West Africa.
(with A. Chibuzor Iloh, A.M. Muellner-Riehl,)

• Evolution, systematics and taxonomy of central European polyploid complexes
Ploidy variation of several central European species complexes (e.g. Sorbus, Ranunculus) is studied in order to elucidate the underlying evolutionary scenarios and draw taxonomic conclusions.
