浮游动物

The relative effects of top-down and bottom-up drivers of zooplankton size structure were examined in three limnologically diverse regions of Quebec, Canada.

浮游动物体型结构在上行和下行作用的相对影响下被研究在三个不同的湖泊区域中。

There was enrichment of the heavier isotope of mesoplankton with increasing grain size, showing carbon isotope enrichment along trophic levels.

中型浮游动物随粒径的增大，其δ13C值增大，显示出营养层次的碳同位素富集作用，但不同粒级组分相互间δ13C值也存在着相当程度的重叠，实际上这也是其生物组分有重叠的反映。

In north-western coastal water of Taiwan, the species in the zooplankton community belonging to warm neritic species, co...

台湾东北沿岸海域浮游动物群落包含来自东海陆架水的种类，例如中华哲水蚤、太平洋磷虾，也包含有黑潮水的热带种和暖水近岸种。

Fry feed on nymphal and larval insects while in fresh water, but once at sea may not feed at all until they become juveniles, when they eat copepods and other zooplankton.

在新鲜的水中，但一旦在海上可能不饲料，直至他们吃桡足类和其他浮游动物时，他们变得青少年，鱼苗喂若虫和幼虫昆虫。

The density of copepods accounted for 72.45% of the total density, and planktonic larvae for 23.41%.

桡足类占浮游动物总密度的72.45%，其次幼虫占23.41%。

The zooplanktonic community was characterised by high richness of species and a greater diversity was observed in the first fish pond, with a superior density of Rotifera.

在第一个鱼塘内具高丰度种和较高多样性浮游动物群体特征被观察，同时伴随较高轮虫密度。

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。

Measurements using opaque bottles almost always reflect community respiration, including bacterial, zooplanktonic, rather than just algal respiration

用不透明瓶测定几乎总是反映出群落呼吸，包括细菌、浮游动物，而不仅仅是藻类的呼吸。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
