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.

日本稻蛙川村蛙的食性

川村飞虫（Dicroglosidae）是一种入侵物种，出现在关东地区的几个种群中，包括日本神奈川县藤泽市。为了估计这种青蛙对生态的影响，我们调查了入侵种群的饮食习惯。我们收集了119个川村F。其中108只（90.8%）有胃内容物，其中包括各种小动物。因此，这种入侵蛙可能会通过对小型本土动物的捕食压力影响生态系统。
