查询词典 zooplankton

The plant floating-bed technology application in Miaojia river showed that the water quality of the plant foating-bed technology applied had preceded evidently than the comparing water, though the water quantity was exchanged largely. There existed a micro-ecosystem at the root aera of floating-bed plant which mainly consists of organic grain, algae, zooplankton, zoobenthos. The mode of "Oenanthe javanica -Ipomoea aqutica" floating-bed mode application realized the whole year run of plant foating-bed technology on polluted water. Hence, the mode is suggested in the following application.

植物浮床技术在苗家河的示范应用研究说明：在水量交换较大的情况下植物浮床技术仍然使示范河段水质优于对照段；浮床植物根际区存在着以有机颗粒、藻类、浮游动物、底栖动物为网络骨干的根系微生态系统：&水芹菜-水蕹菜&浮床模式可实现四季净化污染河水的周年运转，在后续应用中推荐使用此模式。

Therefore, it is impossible for M. mongolica to dominate in zooplankton community in oligotrophic coastal waters. Our results suggest that ecological effects of M. mongolica on structure and function of food web are neglectful in oligotrophic nearshore waters, however, dynamics of population of this species in eutrophic coastal waters and its ecological effects require a further careful investigation.

根据上述结果我们初步推断：蒙古裸腹溞在贫营养型的海洋沿岸带水域中形成较大的自然种群并对近海食物网结构和功能产生重大影响的可能性不大，但该溞在富营养化近岸水域中的种群动态及生态学效应有待进一步研究。

The surface photic zone, where light can penetrate, contains phytoplankton and zooplankton.

表面的有光带，即光可以透过的地方，含有浮游植物和浮游动物。

Urceolaris and Daphnia pulex were studied under the conditions of laboratory. The toxicity research of trichlorphon showed the median lethal concentration（LC50） of three kind of zooplankton in 24h were 318.5mg/L,315.9mg/L, 3.6μg/L respectively.

研究结果表明：在敌百虫的毒性研究中，萼花臂尾轮虫、壶状臂尾轮虫和蚤状溞的24h的LC50分别为318.5mg/L，315.9mg/L和3.6μg/L。

This insidious mechanism, which does not deter the herbivore from feeding but impairs its recruitment, will restrain the cohort size of the next generation of early-rising overwinterers. Such a transgenerational plant–herbivore interaction could explain the recurringly inefficient use of a predictable, potentially valuable food resource—the spring diatom bloom—by marine zooplankton.

但是现在，用桡脚类动物Calanus helgolandicus所做的饲养实验表明，在硅藻与其捕食者之间在进行一场化学战：当被咬碎时，一些早期繁茂的硅藻会释放毒素，杀死以硅藻为食的桡脚类的后代；这样虽然不能阻止桡脚类继续吃硅藻，但却能影响其&兵员补充&，限制来年较早复苏的过冬者的数量。

The coupled model is more sensitive to phytoplankton maximum growth rate, respiration rate, death rate and zooplankton grazing rate, while other parameters such as half saturation constants and remineralization rate are insensitive ones.

虽然，从表面上来看，模型对垂向扩散系数的敏感度不大，但由于目前的湍封闭模型，尚不能很好地刻画扩散系数复杂的时间变化，这势必对生态系统的模拟有着较强的不确定性。

The zooplankton was mainly contributed by copepods, and its dominant species were mostly eutrophication indicators: Keratella cochlearis, Polyarthra trigla.

水库的主要优势种为轮虫，而且优势种所出现的种类多为富营养化指示种，如：螺形龟甲轮虫Keratella cochlearis、针簇多肢轮虫Polyarthra trigla。

In addition there are several dominant classes, including Filinia longiseta. Trichocerca、Polyarthra trigla、Brachionus angularis and Brachionus calycflorus, which contained 91.8% of total zooplankton.

另外，萼花臂尾轮虫、长三肢轮虫、角突臂尾轮虫、针簇多肢轮虫、异尾轮虫均为优势种，合计占浮游动物总数的91.8%。

Using unsterile raw water as culture medium, at 23℃, the Microcystis aeruginosa disappeared gradually, this was related with occurrence of great amount of zooplankton.

以未灭活源水为培养基，23℃时，发现铜绿微囊藻逐渐消亡，这与微型浮游动物的大量出现有关。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
