Current research interest

Evolutionary and community ecology of predator and prey interactions I have a strong interest in topics relating to predator and prey interactions. In my earlier research, I studied phenotypic plasticity in predator and prey species from an adaptationist perspective. Recently, most of my research effort involves exploring the impacts of individual phenotypes on predator-prey interactions and the effects of those interactions on population- and community-level properties. At present, I primarily study freshwater communities in forest ecosystems by conducting manipulative experiments both in the laboratory and in the field. In particular, I have been focusing on the intriguing life histories of salamander larvae (Hynobius retardatus) and frog tadpoles (Rana pirica). In my work, I have been fortunate in having the opportunity to colluborate with many fine scientists, and I have also had many able student helpers in my lab. To improve our understanding of the nature of predator-prey interactions and contribute further to the field of animal ecology, I hope to conduct many amazing field experiments in the experimental forest of Hokkaido University with  students in my lab and my great collaborators.
