CRC 1211 Atacama Desert Population Genomics

Living at its dry limits! Within the framework of the DFG funded Collaborative Research Center (CRC1211) this project aims to explore spatio-temporal gene-flow between plant populations over the entire Atacama Desert, ranging from small populational scale to landscape-scale. Our preliminary data shows that vegetation growth and vegetation patterning of Tillandsia lomas at its dry limits in the Atacama Desert displays fine-scale response to various environmental parameters as a result of longterm evolutionary adaptation processes.

The CRC aims to pioneer the research on the mutual evolutionary relationships between Earth surface processes and biota. The target areas are arid to hyper-arid systems, where both biota and Earth surface process are severely and predominantly limited by the availability of water.

Johanna Möbus is working on this project as PhD student.

AgroBioDiv

AgroBioDiv is an interdisciplinary, participatory project funded by the Ministry of Science, Research and the Arts Baden-Württemberg, blending expertise in the fields of biology and political science to foster biodiversity within larger landscapes. The project aims to develop integrated strategies and political instruments for increasing biodiversity in Baden-Württemberg through organic agriculture for long-term sustainability. The biodiversity of agricultural fields will be measured and observed with farmers and conservationists in various case study regions. Applying discourse analysis, the problem definition of biodiversity loss will be examined within local political processes through observation of meetings and interviews with decision-makers.

Laura Kellermann is working on this project as PhD student.

Convergent Evolution in Plant Diversification

Life in general, and plants in particular, adapt to a new environment on evolutionary time scales. Studying adaptation is essential if we aim at understanding how life persists in the face of changing environments, a topic of immediate relevance in today’s world. Within the Brassicaceae family the tribe Arabideae is one of the most prominent tribes and it displays parallel and convergent evolution at best with roughly 500 species Within this DFG funded project we are using comparative genomic approaches to seek for genomic footprints of parallel evolution of the plants morphospace explaining convergent phenotypes and also selected complex traits.

With Mai 2022 Dr. Nora Walden will complement our team.

Orchid Landscape Genomics

In Germany more than 30% of the vascular plant species are endangered and often found only in protected areas. Here we focus on orchids from the genus Platanthera to unravel its evolutionary history, taxonomic richness, landscape genomics and its indicator value as environmentally sensitive organisms. We collaborate with state authorities and numerous collaborators from all over Europe to develop strategies for species´ and landscape management and protection.

Jonas Bleilevens is working on this project as PhD student.

The project is funded by Naturschutzfonds Baden-Württemberg.

Other selected projects

Other long-term projects are focusing on the genus Dianthus, being the result of one of the fastest plant radiations of the past 2 million years, and in particular unravelling the population decline and threat caused by global warming. We are focusing in particular on Cheddar Pink (Dianthus gratianopolitanus), a critically endangered species from cliffs and rocky outcrops widely distributed in Central Europe. Alexandra Winizuk is working on this project as PhD student.

The enigmatic plant Cardamine bulbifera is reproducing vegetatively only. We are elaborating the evolutionary history of this plant, which may have originated in the Caucasus region and expanded and diversified into Central European woodlands, successful but without sex; and Yalu Ru is working on this project as PhD student.. 

Our research on the genus Hypericum addresses questions how non-sexual reproduction may serve as a genetic buffer and reservoir to freeze gene pools temporarily, and which than be activated under changing environmental conditions.

The evolutionary significance of cold adaptation is studied in the genus Cochlearia and selected Arabis species. The Cochlearia project is supported by Dr. Eva Wolf (Academy of Sciences Baden-Württemberg, Heidelberg).

Various short-term projects most often target biodiversity and species-conservation issue of practical and immediate relevance. Selected taxa comprise aquatic plants such as Nymphaea candida and Nuphar pumila, canyon forest plants such as Anthriscus stenophylla with less then five populations in Baden-Württemberg, or the attractive litter meadow plant Gladiolus palustris. More recently also animals such as the Crested Newt (Triturus cristata) are in our focus of regional protection strategies to be developed.
