摘要
以吉林省长白山地区兴林林业局、泉阳林业局、蛟河市天北镇3个地点375只半人工养殖的1～5龄的东北林蛙为研究对象,根据体质量、体长、后肢长、前肢长4个重要指标的变化,分析了东北林蛙变态后的生长发育规律。结果显示：雌雄之间有着明显的二型性;Logistic、Gompertz和Von Bertalanffy方程的拟合分析显示,雌性体质量增长速率开始下降时间在2龄以后,较雄性滞后近1 a,雌性和雄性林蛙的体长、前肢长、后肢长增长速率开始下降的时间均在1龄以内。1龄和2龄是东北林蛙生长发育的关键时期,应加强这一时期的饲养管理。
The post-metamorphic growth pattern of the Northeast China brown frog （Rana dybowskii） was studied by measuring four parameters including body length, body weight, posterior limb length and forelimb length of 375 individuals aged from one to five years from three geographic sites, namely, Xinglin Forestry Bureau, Quanyang Forestry Bureau and Tianhei Town in Changbaishan Mountains of Jilin Province. Result indicates a significant sex dimorphic growth pattern. Simulation by Logistic, Gompertz and Von Bertalanffy models demonstrates the time when the growth speed of body weight starts to decline for the female is after two-year old, about one year later compared with the male, while the declines of growth speed of body length, forelimb length and posterior limb all occur within one-year old for both sexes. This suggests that the first two years are the most important developing phase for brown frog and much attention should be paid to farming management.
