丹东地区北方狭口蛙生活习性的观察研究

北方狭口蛙生活习性较其它蛙类特殊,为探明其生命活动规律,采用野外定点观察,实验室饲养、剖检相结合等方法,对其生态习性和繁殖习性进行了研究。结果显示,北方狭口蛙的活动规律与气温变化有关;繁殖期与雨季早迟、雨量大小、气温、水温等因素有关;抱对交配产卵多发生在傍晚、夜间及清晨,雌雄蛙交配产卵后,雄蛙又可与第二只雌蛙再次抱对,交配产卵,产卵量因个体差异而不同。

Living Habits of Boreal Digging Frog in Dandong:Observation and Study

Boreal digging frog （ Kaloula borealis） has special living habits. Field fixed - point observation and laboratory feeding/necropsy methods were used to investigate its ecological and breeding habits. The results indicate that the habit pattern of boreal digging frog is subjected to environment temperature; rain time, rainfall, air temperature and water temperature affect when it breeds, its mating and spawning behaviors often occur in the evening, night and early morning; a male frog can mate with a second female after it mate with the first one and make it lay eggs; the spawn quantity fluctuates due to individual differences.
