| 为研究隆线溞Daphnia carinata、锯缘真剑水蚤Eucyclops serrulatus及中华薄壳介 Dolerocypris sinensisS三种甲壳纲动物与萼花臂尾轮虫Brachionus calyciflorus种群的相互关系,分别将其以不同接种密度与萼花臂尾轮虫(接种密度为0.35 ind/mL)进行混合培养。结果表明,三种甲壳纲动物对萼花臂尾轮虫的种群生长均有抑制作用,随着接种密度的增加,轮虫种群受到的抑制作用增大。随着培养时间的延长,这种抑制作用可以导致轮虫种群消亡。在轮虫接种密度一定的情况下,三种甲壳纲动的种群变化有所不同。受到轮虫的竞争,当接种密度较低时,隆线溞种群生长受到明显抑制；当接种密度较高时,轮虫对其种群生长抑制作用无从发挥,隆线溞在混合培养与单独培养下的种群变化基本一致。与隆线溞不同,锯缘真剑水蚤和中华薄壳介的种群生长受到轮虫的促进。与锯缘真剑水蚤相比,中华薄壳介在混合培养下的种群增长速度较慢。 |

| Three species of crustacean zooplankton i.e. Daphnia carinata, Eucyclops serrulatus, Dolerocypris sinensis,Sand Brachionus calyciflorus were cultured at seven initial densities with Brachionus calyciflorus inoculated at density of 0.35 ind/mL. The controls were made by mono-culturing of these species at corresponding inoculating densities, respectivly. The results showed that the population of B.calyciflorus was suppressed by all of the three species of crustacean zooplankton. The suppression enhanced with initial inoculation densities of them and caused extinction of the B.calyciflorus at the end of some cultures. The population of D.carinata, E. serrulatus, and D. sinensisSchanged differently, however, compared with their respective controls, as they were cultured with the B.calyciflorus. For D. carinata, the population was inhibited by the B. calyciflorus at lower inoculation densities and the inhibition became negligible with increase of the inoculation densities. This suggested a competitive relationship between the D. carinata and the D. carinata, and the D. carinata was superior to the B.calyciflorus in this relations. Different in behavior from that of the D. carinata, both of the E. errulatus and the D. sinensisSwere promoted in population as they were cultured with the B.calyciflorus. The extent of promotion for the D. sinensis was found higher the extent for the E. errulatus. Result of present study denied existence of competitive relation between E.errulatus and B.calyciflorus and between D. sinensis and B.calyciflorus. |
