|Outline of Final Research Achievements
Previous our studies have revealed for the first time that biofilm on the surface of tidal flat sediments serves as a major food source for small sandpipers, causing a paradigm shift in the food web structure of tidal flat ecosystems. In order to extend this new research field dealing with the bird-biofilm direct linkage to the central field of ecology, i.e., food web structure and functioning, we performed field observations, mesocosm experiments, and analyses combining ecology, physiology, morphology, and phylogeny. Namely, our study focused on the reasonable explanation of the biofilm feeding by shorebirds from the viewpoint of optimum foraging theory and adaptive evolution of individual-level traits.
