浮游动物

This system found in some animals, and most of the coelenterate porous, they are Camp fixation living or planktonic life, from either side of the body to stimulate feelings or obtain food.

这种体制见于部分多孔动物和多数腔肠动物，它们营固着生活或浮游生活，能够从身体的任何一面感受刺激或取得食物。

The terrestrialand aquatic environmental impacts of veterinary drugs was expounded both on terrestrial environmental impacts of veterinary drugs upon plants, soil animals, soil microorganism and protozoa, and ecotoxicity of veterinary drugs to plankton, microorganism, fish and Crustacea.

综述了兽药对陆生和水生生态环境影响方面的研究进展，探讨了兽药对陆生植物、土壤动物、土壤微生物与原生生物等陆生生态环境的影响及对浮游类生物与微生物、鱼虾与水体甲壳动物等水生生态环境的影响及其生态毒理效应。

Other forms of food are planktonic crustaceans and algae that may develope on coral or nearby rocks.

其他形式的食物是浮游甲壳类动物和藻类，可能制定关於珊瑚或附近的岩石。

To find a method to prevent algal blooms,the degradation of growing Microcystis aeruginosa and Planktothrix mougeotii by several predacious microanimals (Trithigmostoma cucullulus,Philodina erythrophthalma,Aeolosoma hemprichi,Moina macrocopa and Monas guttula)and the effect of microanimals by ring-lace were studied using a large scale lake simulator.

为了探索治理蓝藻水华的方法，利用大型湖泊模拟装置，研究了几种捕食性微小动物(僧帽触口虫、红眼轮虫、红斑飘体虫、多刺裸腹溞以及点滴虫等)对铜绿微囊藻及孟氏浮游蓝丝藻生长的抑制作用以及人造根对微小动物的作用。

We argue that the changes in meroplankton abundance, coincident with increased phytoplankton and declining holoplankton, reflect the synchronous effect of rising SST and related changes in the pelagic community on the reproduction and recruitment of many benthic marine invertebrates.

我们推断季节性浮游生物丰度的变化与浮游植物的增长和终生浮游生物的减少是保持一致的，是海水表面温度上升的反映，并与许多远洋底栖无脊椎动物的生殖生长相关。

This paper summarizes research status and progress on classification and ecology of pelagic tunicates in China and abroad, and introduces in detail the basis of classification, current status and trends in Appendicularia and Thaliacea research.

综述了国内外浮游被囊动物分类和生态研究的现状和进展，综述介绍了有尾纲和海樽纲的分类依据、研究现状、趋势和在海洋生态系统中的作用。

Minute floating marine tunicate having a transparent body with an opening at each end.

身体透明、两端有孔并且有背囊的微小的浮游海洋动物。

Tunicata, belonging to Urochordata, is comprised of three classes: Appendicularia, Thaliacea and Ascidiacea, with the former two being planktonic while Ascidiacea benthic.

被囊动物是一类低等脊索动物，包括3个纲：有尾纲、海樽纲和海鞘纲；全部生活在海洋里，其中有尾纲和海樽纲营浮游生活。

This sea creature seem like jellyfish and its call Ascidia.

这种类似水母的动物被称之为&樽海鞘&，以水中的小型浮游植物——海藻为食。

本文根据浮游及底栖动物种群结构和数量分布特点，对秦皇岛市洋河进行了初步评价。

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%.
