Profile

Prof. Shimada studies ecological science, especially population, behavioral and evolutionary ecology. He investigates not only population dynamics of experimental systems with legume seeds, seed beetles and parasitic wasps, integrating computer simulation from the complex system point of view, but also phylogenetic relationship between legume plants and seed beetles from the coevolution and biodiversity points of view. He collaborates with Instituto de Ecologia (Xalapa, Veracruz St., Mexico) for research on Mexican seed beetle biodiversity.

Prof. Shimada also studies behavioral and movement ecology of a pteromalid parasitic wasp attacking seed beetle larvae infesting legume seeds. The wasp shows choice behaviors between two closely related seed beetles with odor cue based on learning and frequency-dependent preference, generating three species coexistence for a long time with beetles' anti-phase oscillations. Therefore, predators' learning may promote prey's biodiversity higher in nature.
In addition, Prof. Shimada is a member of the Regulation and Approval Committee for genetically modified crops in the national government (MAFF and ME, Japan), based on Cartagena Protocol.
