查询词典 Cladocera

Species of zooplanktons were identified in Huangjiahu Lake (31 protozoa, 39 rotatoria, 13 cladocera, 5 copepod).

随着湖泊水草生物量的增加，浮游动物的多样性指数也随之而增加。

We both were attracted by Crustacea, particularly by Cladocera.

我们俩对甲壳动物，特别是枝角类甲壳动物深深着迷，全神贯注地研究这一生物种群并进行收集工作。

In April 2002, 33 species of planktonic crustacea in 26 genera (11 Copepoda and 22 Cladocera) were sampled from 17 sites in the middle and lower reaches of the Hanjiang River, the largest tributary in the middle reaches of the Yangtze River.

2002年4月，在汉江中下游从丹江口坝上至其河口沿途设17个采样点，共采集到浮游甲壳动物10科26属33种，其中桡足类4科10属11种，枝角类6科16属22种。

Therefore, fish's predatory control on zooplankton is higher in shallow lakes, resulting in less possibility of grazer control of algae by the Cladocera.

下行效应在浅水湖泊中可能更为重要，因此浅水湖泊中滤食性鱼类对浮游动物的捕食控制可能更强，导致枝角类几乎不可能通过牧食控制藻类的生长。

Biological Activated Carbon Filter could provide ideal habitats for invertebrates, but invertebrates may lead to aesthetic problems and adverse health effects of drinking water. This paper studied the invertebrates in biological activated carbon filters in a water plant of the south of China during Sep. 2006 to Sep. 2007. The results implied that BAC filters were colonized by invertebrates, in which 23 species of invertebrates were found, the dominating organism group was the rotifer, and others included Copepoda, Cladocera, Oligochaeta, Nauplii and Nematoda.

生物活性炭(Biological activated carbon， BAC)滤池能够为无脊椎动物提供理想的生境，但无脊椎动物可能给饮用水带来负面的健康效果和感观问题。2006年9月～2007年9月，对南方某水厂BAC滤池无脊椎动物滋生状况进行了为期13个月的调查研究，共发现无脊椎动物23种，优势类群为轮虫，其他类群还有桡足类、枝角类、寡毛类、无节幼体、线虫等。

During the period the author has particulanly studied in ecology and cultural technology of cladocera and rotifer.

在此期间，作者主要从事枝角类和轮虫的生态学及培养技术等方面的研究，内容包括：第一部分淡水枝角类批量培养的基础研究。

Food compositions of M. albus were investigated in areas of three counties in Hubei province. Diets of the M. albus with body length less than 100mm change with their growth: from Rotifera and Cladocera to Oligochaeta and Chironomidae.

通过对不同产地的271尾野生黄鳝的食性的研究表明，全长小于100mm的稚鱼，其食性随着全长的生长而变化，稚鱼前期以摄食轮虫、枝角类为主，后期以水生寡毛类、摇蚊幼虫为主。

However, the food composition of the M. albus with body length more than 100mm were quite consistent, with Chironomidae, Oligochaeta, Pheretima, Cladocera, Copepoda and insect larvae as the major food items.

而全长101-200mm的幼鳝及全长大于200mm的成鳝的食性，随全长变化相对稳定，且幼鳝和成鳝的食谱基本相同，其主要食物组成均包括摇蚊幼虫、水生寡毛、蚯蚓、昆虫幼虫、枝角类和桡足类等。

This study is to investigate the algae control by cladocera filtration process.

本研究之目的在於探讨水蚤滤食对藻类生长控制的情形。

The first feeding appears on the third day after hatching. The first food of larvae is Rotifera, But if Cladocera predominates in water, the first food can also be small Cladocera .

仔鱼3d龄开口，主要以轮虫为开口饵料，在食物中枝角类占绝对优势时，以小型枝角类为其开口饵料。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
