| 摘 要： | 蒙新河狸为国家一级保护动物,数量稀少,属濒危物种。通过对该物种采食对策的初步观察研究,结果表明:在食物选择上,蒙新河狸对径级为1～3 cm的树木呈正选择。蒙新河狸家域最主要的采食区域为巢穴上下游100 m范围内,主河道两岸10 m范围内。蒙新河狸采食主要选择2年生的树木和多年生的大树(7 cm以上)。

| Abstract: | Castor fiber brirula,whose number is rare,is first class national protected animals,being endangered species.Feeding strategies of this species were preliminarily observed & studied.Result shows that: in the choice of food,Castor fiber brirula appears positive selection on the diameter class of the 1-3 cm.The main feeding range of Castor fiber brirula home range is 100 m upstream and downstream within the nest,10 m range in both sides of main channel.Castor fiber brirula mainly choose 2-year-old trees & per... |
