英文摘要本文对蒙古裸腹(MOInAMOngOlICAdAdAy)一休眠卵所孵化的孤雌生殖个体进行连续15个世代的培养,最终统计、比较不同世代的生长与生殖。结果表明:(1)蒙古裸腹孤雌生殖雌体的体长与日龄呈正对数相关关系,其平均寿命为8.4±5.5d,87.5%的寿命在两周以内。蒙古裸腹产幼前发育期通常为6~7d;一生平均繁殖1胎,每胎产8.2±4.0只幼体。(2)不同世代蒙古裸腹的平均生殖量和净生殖率(r0)随世代数的增加而呈现出衰退趋势;其生长、繁殖次数、内禀增长能力(rM)、世代平均周期(T)以及增长的周限速率(λ)随世代数的不同而有所波动,但与世代数没有明显的相关性。; FiFteen Moina mongolica parthenogenetic generations were continuously cultured and the growth and reproduction in diFFerent generations were investigated.There are two results.1.A posltlve logarithmic regression between the parthenogenetlc Female body length and day is Found, the average longevity of Moina mongolica being 8.4±5.5d, 87.5% in two weeks.The perlod beFore sex mature generally is 6-7d.During its liFe Moina mongolica propagates once,averagely 8.21±4.0larvae per time.2.To the diFFerent generations of Moina mongolica, the trend of the average Fecundity and the net reproductivity is declinable.The growth, lntrinsic rate of increase, generation time and Finite rate of lncrease are diFFerent with diFFerent generations, but without obvious relationship with the number of generations.; 福建省自然科学基金!C95005
