Effects of periodical starvation on the characteristic parameters of population of Brachionus plicatilis

摘要

摘要: 实验设置了一直投喂、周期性饥饿1,2,3,4d和一直饥饿6个处理组,采用轮虫单个体培养,检验周期性饥饿对褶皱臂尾轮虫(Brachionus plicatilis)实验种群特征参数的影响.结果表明:一直投喂组的生殖价最高,对轮虫种群的潜在增长最有利,随饥饿强度的增大,生殖价减小.不同处理下,轮虫个体寿命与其生殖期之间存在显著的正相关(r=0.747).轮虫在受到饥饿后,寿命略有增长,但不同处理对轮虫的平均寿命(10.8~13.1d)和生殖期(6.3~8.3d)均未达到显著差异(P>0.05).饥饿强度增大时,轮虫个体的总产幼数、总产卵量显著下降(P<0.05),产第1幼、最后1幼、第1卵、最后1卵时间显著延长(P<0.05);同时,种群参数的世代时间(T)随饥饿强度增加而增大,内禀增长率(r_m)、周限增长率(λ)和净生殖率(R₀)却明显下降.

Abstract: Six treatments (fed throughout experiment;alternate starvation and refeeding at equal duration of 1 d, 2 d, 3 d and 4 d, respectively;star vation throughout experiment) were carried out to test effects of periodical starvation on the characteristic parameters of population of Brachionus plicatilis,and each treat ment was performed in 12 replicates of individual cultures.The results showed that the group fed throug hout experiment had a to preproductive value (indicated best potential population growth),and the longer starved, the lower the reproductive value.Statistical analyses also showed that individual lifespan and its reproductive period shared significantly positive correlation (r= 0.747) at different treat ments.Under starvation, the rotifer's lifespan was slihtly elongated, but mean lifespan (10.8~13.1 d) and reproductive period (6.3~8.3 d) had no difference among six treat ments (P > 0.05).While starvation increased, total larvae and total eggs were sharply decreased (P< 0.05),but the time for the first and lastegg, for the first and last larva was significantly post poned (P< 0.05).At the same time, rotifer's generation time (T) also gradually increased, but intrinsic rate of increase (r_m),finite rate of increase (K) and net reproductive rate (R₀) obviously decreased.
