摘要
对分布于胶东昆嵛山脉的东方铃蟾的种群特征和繁殖生态进行了研究, 其年龄组可分为幼体组(1-31 %)、亚成体组(13-16% )、成体Ⅰ组(31-58% ) 和成体Ⅱ组(53-95% ), 雌雄性比为1-16∶1。根据发育程度成体卵巢中的卵可分为5 种类型。通过详细的测量和分析, 表明繁殖期成体的机能形态学指标表现出与生殖状态相关的明显而复杂的变化。
The properties of population and breeding ecology were studied on Bombina orientalis at Kunyu Mountains in eastern Shandong Province.According to the weight length curve,they were divided into 4 age-groups and sex rate was 1.16∶1(♀∶♂).The eggs can be classified into 5 types.In the breeding phase the morphological index in different age-group were shown markedly change related to the breeding condition.
