|Outline of Final Research Achievements
Individuals are not uniform even within a species. Using a forest pond community as a model system, I experimentally explored ecological consequences of intra-population trait variation in a predator and prey species. I found that Intra-population trait variation of predator (Hynobius retardatus, salamander larvae) and prey (Rana pirica, tadpoles) species strongly dictate structure of inter-specific interactions through occurrence of intra-specific interaction such as cannibalism and apparent competition. Importantly, such effects translate into impacts on demography and evolution of community members and material flow within and between ecosystems. This study generally highlights that incorporating trait variation within a species into community ecology is imperative to deepen our understanding of dynamics and function of ecological community in nature.
