Abstract

Fejervarya kawamurai (Dicroglossidae) is an invasive species occurring in several populations in the Kanto region, including Fujisawa City, Kanagawa Prefecture, Japan. To estimate the ecological impacts of this frog, we investigated the food habits of invasive populations. We collected 119 individuals of F. kawamurai. Of these, 108 (90.8%) had stomach contents that included various small animals. Therefore, this invasive frog might influence the ecosystem via predation pressure on small native animals.
