应用生命表统计学方法,在13℃、18℃、23℃和28℃下对采自芜湖市莲塘湖和荷花塘水体中的萼花臂尾轮虫三个姐妹种HEl、HE3和LE9的生活史特征进行了比较研究.结果表明,三个姐妹种生命表参数间的差异因温度的不同而异.13℃下,姐妹种LE9的生命期望、平均寿命和世代时间都显著长于姐妹种HE3,LE9的净生殖率和种群内禀增长率均最大,三个姐妹种所产后代中的混交雌体百分率无显著的差异.18℃下,姐妹种LE9的生命期望和平均寿命显著长于姐妹种HE3,姐妹种LE9的世代时间显著长于姐妹种HE1和HE3,姐妹种HE3的种群内禀增长率显著高于姐妹种LE9,姐妹种HE3所产后代中的混交雌体百分率最高,三个姐妹种的净生殖率无显著的差异.23℃下,姐妹种HE1的生命期望、平均寿命和世代时间均最长,姐妹种HE1所产后代中的混交雌体百分率显著低于HE3,三个姐妹种的净生殖率和种群内禀增长率均无显著的差异.28℃下,三个姐妹种的生命期望、平均寿命、世代时间和种群内禀增长率均无显著的差异;姐妹种HE1的净生殖率最低;姐妹种HE3所产后代中的混交雌体百分率最高.三个姐妹种的生命表参数对升高的温度的响应也不相同.温度、姐妹种及两者间的交互作用对轮虫的世代时间、平均寿命、出生时的生命期望和轮虫所产后代中的混交雌体百分率均有显著的影响;温度和姐妹种对轮虫的净生殖率和种群内禀增长率均有极显著影响,但两者的交互作用对其无显著性影响.

Life history characteristics of three sibling species including sibling HE1,HE3 and LE9 in Brachionus calyciflorus species complex collected from Lake Liantang and Pond Hehuatang in Wuhu City and cultured at 13℃,18℃,23℃ and 28℃ with 2.0×106 cells/mL of Scenedesmus obliquus was compared by means of life table demographic approach.The results showed that the differences in life table parameters among the three sibling species differed with temperatures.At 13"C,sibling species LE9 had longer life expectancy at hatching,average lifespan and generation time than sibling species HE3,and the highest net reproductive rate and intrinsic rate of population growth among the three sibling species.The percentage of mictie females in all produced offspring was similar among the three sibling species.At 18℃,sibling species LE9 had longer life expectancy at hatching and average lifespan than sibling species HE3,and longer generation time than sibling species HE1 and HE3.Sibling species HE3 had higher intrinsic rate of population growth than sibling species LE9,and produced the most mictic daughters among the three sibling species.However,the net reproductive rates were similar among the three sibling species.At 23℃,sibling species HE1 had the longest life expectancy at hatching,average lifespan and generation time among the three sibling species.Sibling species HEI produced less mietie daughters than sibling species HE3.Both net reproductive rate and intrinsic rate of population growth was similar among the three sibling species.At 28℃ and among the three sibling species,life expectancy at hatching,average lifcspan,generation time and intrinsic rote of population growth were all similar,sibling species HE1 had the lowest net reproductive rate,sibling species HE3 produced the most mietic daughters.The responses in life table parameters to increasing temperatures were different among the three sibling species.Temperature,sibling species and their interactions all significantly influenced generation time,average lifespan,life expectancy at hatching and percentage of mietic females in the produced offspring.Both temperature and sibling species affected markedly the net reproductive rate and intrinsic rate of population growth,but their interactions did not appear to be significant.
