Eco-evolutionary dynamics of predator-prey systems : experimental study using plankton microcosms

点击翻译按钮获取中文摘要

Organisms can evolve at a very short-time scale and such rapid evolution has been reported by many studies. This study focused on how rapid evolution influences population and evolutionary dynamics. I found that there was a substantial variation in the shape of a tradeoff between predation resistance and competitive ability in an algal population, which produces the genetic diversity that makes rapid evolution possible to occur. Then, I observed strange population dynamics of a predator-prey system, depending on the shape of the tradeoff.
