摘要: 于2004~2005年冬季对上海农田泽蛙的蛰眠状况进行了初步调查。结果表明,农田中的路径、田埂和沟渠岸边地下洞穴是泽蛙的主要越冬场所。蛰眠洞穴共用率高达34.0%,超过62.2%的泽蛙与其它个体共用洞穴蛰眠,各共用洞穴内的泽蛙只数为2~6只不等。泽蛙主要利用已有的地下洞穴蛰眠。86.6%蛰眠期的泽蛙为1龄个体。

Abstract: An investigation in the wintertime of 2004-2005 showed that in Shanghai farmland, the underground burrows of ridges, footpaths, and ditch banks were the main hibernation sites of Rana limnocharis. More than 62.2% of the frogs hibernated with other individuals, and the frogs, with 2-6 in a burrow, shared 34.0% of the burrows. 86.6% of wintering frogs were sub-adults. R. limnocharis mainly used the existing burrows to hibernate.
