Summary
The increase in world population and dramatic decrease in catch of eel highlights the dynamic changes in population of different species in the ecosystem. Why are the population sizes changing? Ecologists have shown that population dynamics are affected by various factors, such as climate change, food depletion, and natural enemies. Recent studies have found that adaptive evolution can be rapid enough to affect contemporary population dynamics. The effects of rapid evolution on ecology and feedbacks between them (eco-evolutionary feedbacks) have been investigated intensively in predator-prey systems by theoretical and experimental approaches. In this seminar, I will talk about the importance of mechanisms of rapid adaptation including phenotypic plasticity, introduction timing of genetic variation, and the number of loci controlling ecological traits.
