摘　　要：采用野外定点观察、室内剖检相结合的方法 ,对北方狭口蛙 (Kaloulaborealis)繁殖生态进行了研究。北方狭口蛙繁殖期直接与每年的雨季迟早有关 ,多在大雨过后的傍晚、夜间及清晨进行繁殖活动 ,产卵场所为大雨过后形成的临时水坑或流速较缓的沟渠中 ,产卵场所不受水域大小及水中有无杂草所限 ,卵分批连续产出 ,每批产卵约 2 0 - 30粒。The reproduction ecology of frog Kaloula boreals was studied by both outdoor observation and indoor dissect vivisection.The period of reproduction is related to the yearly rainseason,and the frog reproducts at dusk,night or early morning of days after heavy rain.Spawning spots,regardless of size of water area or grass in the water,are pits by the heavy rain or canals with slow flow.Eggs are spawn continually in batches with 20-30 eggs each.
