=> Awardee talk entitled: "Aspects of life in small populations: inbreeding, environmental stress and phenotypic plasticity"


Plants growing in small populations face several challenges. When environmental conditions change, plants have to adapt or respond plastically. Moreover, they can only choose their mates from the small pool available, so inbreeding is more frequent than in large populations. When pollinators are declining or not attracted by the few plants of a rare species, plants may even have to completely rely on selfing for reproductive assurance. As a consequence, inbreeding reduces offspring fitness (“inbreeding depression”) and can influence plant functional and reproductive traits. However, environmental change and inbreeding depression usually are not independent, and it is often assumed that inbreeding depression generally increases under stressful conditions. In my research I am taking these aspects of small populations into the greenhouse or common garden to study the effects of inbreeding and environmental stress on various aspects of plant life under controlled conditions. I will present evidence from different plant species to show which types of stress do or do not increase inbreeding depression, and I will explain effects of inbreeding on phenotypic plasticity, and modifying effects of plant size on inbreeding-stress interactions. Finally I will bring these findings back to natural populations and discuss the effects of inbreeding on the success of ex situ plant conservation.
