Research Area “Molecular Biodiversity and Adaptation”

This research area aims to identify molecular and chemical mechanisms underlying organismal diversity, interaction networks and (co-)evolutionary processes that lead to local adaptation, population differentiation and speciation. This includes the functioning of complex organismal communities, such as micro- and holobiomes.

Research questions

Which chemicals drive organismal interactions and adaptation to environmental change?

Chemicals are important for communication between plants, microbes and animals. Tapping into this chemical communication is essential to understand how biodiversity emerges and is maintained.
Computer-assisted approaches for metabolite identification reveal novel chemical cues in intraspecific communication and multitrophic networks (Complexity, Functions). Novel plant metabolites may be used for sustainable resistance in agro-ecosystems (Society).

What are the molecular mech­a­nisms underlying functional links in highly diverse micro­biomes and their hosts?

Microbial communities are important drivers of ecosystem functioning as well as the performance of macro-organ­isms. 
Molecular tools help to identi­fy micro­bial communi­ties, their inter­actions and their functions (Complexity, Functions). iDiv reserachers will inte­grate ecological concepts and holo­biome data with information on human micro­biomes to better under­stand how complex micro­biomes can be maintained under environmental change (Society).

How does environmental change impact the evolutionary processes underpinning local adaptation, population structure and speciation?

Organisms adapt to environmental change, which leads to population-genetic divergence and speciation.
Genomic analyses reveal the evolutionary consequences of global change on local adaptation, speciation and population differentiation (Complexity). Local adaptation and eco-evolutionary processes influence how populations respond to global change (Change).
