Plant evolutionary trajectories in fragmented heterogeneous environments

Plant evolution in Mediterranean cliff habitats

Why Mediterranean Cliffs?

Mediterranean cliffs serve as exceptional natural laboratories for studying evolutionary dynamics. These habitats represent a unique example of fragmentation, where a naturally discontinuous landscape is further exacerbated by human activity. Characterized by strong geographical barriers and a complex mosaic of environmental conditions over short distances, cliffs challenge plants to adapt rapidly. My research investigates how plants cope with these heterogeneous and stressful environments, shedding light on the evolutionary mechanisms and adaptive strategies required for survival. To explore these dynamics, I utilize two key model systems: the wild carnation Dianthus rupicola and the wild relative of cole crops, Brassica incana. By studying these species, I aim to uncover how populations diverge and persist in the face of ecological isolation and environmental stress.

Plant adaptation to urban pollinators

Why urbanization?

Urbanization is rapidly expanding worldwide, challenging plant and animal persistence or driving their evolutionary changes. By showing distinct biotic and abiotic environmental conditions compared to surrounding non-urban areas, urban environments are emerging as an ideal setting to test fundamental evolutionary hypotheses. These include parallel adaptation, particularly in response to urban pressures that alter plant-insect interactions. To investigate these mechanisms, Trifolium repens (white clover) serves as an excellent model system. Its global ubiquity allows for powerful comparative studies, enabling us to disentangle how complex urban drivers shape plant responses on a broad geographic scale.
