日本を越冬地および中継地とする2種の長距離移動性ガン類の餌資源植物:窒素含量の時系列変動
Nitrogen acquisition by Greater White–fronted and Bean geese from late autumn to early spring, was studied in Japan. Samples of food plants were collected from eight major locations throughout late autumn 2005 to early spring 2006, and analyzed for nitrogen content. Major food sources were waste ric...

Samples of food plants were collected from eight major locations throughout late autumn 2005 to early spring 2006, and analyzed for nitrogen content. Major food sources were waste rice grains, post-harvest soy beans and corn and secondary rice stems, together with several wild grasses and barley/wheat sprouts growing on rice fields.
