zooplasty

From september 2000 to august 2001 , we collected the zooplanktons qualitatively and quantitatively at 12 sampling sites in the river and measured 3 physical indexes ( temperature , ph and electric conductivity ) and 5 chemical indexes ( nh3 - n , tp , tn , codmnand do ) . through identifing the zooplanktons “ category , the common and the dominant species were ascertained 2000年9月至2001年8月,在內河的主要河道設置12個采樣點,對浮游動物進行定性和定量的采集,同步進行溫度、 ph值和電導率三項物理指標以及氨氮、總磷、總氮、高錳酸鹽指數和溶解氧五項化學指標的測定。

Humic acid usually formed from phytoplanktons , zooplanktons , and epicontinental vascular plants through biodegraded and condensated reaction . krogen derived either from humic acid or from the reworking materials . differing from humic acid and kerogen , bc was produced from the incomplete combustion of fossil fuels and biomass 并且不同的有機質有不同的來源,腐殖酸通常是浮游生物和陸生的高等植物經過生物降解、聚合等過程形成的;干酪根是腐殖酸進一步演化而成,既有原生的也有異地遷移而來的;碳黑則不同于腐殖酸和干酪根,它是生物質和煤、油等化石燃料經過燃燒產生的。

A dynamic model for dissolved inorganic nitrogen ( din ) and phosphate ( po4 - p ) cycles and budgets in jiaozhou bay was established according to the principles of d - n - p - z model . in the model , 6 state variables ( din , po4 - p , phytoplankton , zooplankton , organic detritus , and dissolved organic nutrients ) were included . logically this model was divided into three modules - nutrients input , nutrients cycle in seawater , and output of both dissolved substances ( e . g 本文根據n ? p ? z ? d模型的基本原理,建立了膠州灣氮、磷營養鹽循環收支動力學模型,主要包括營養鹽輸入,營養鹽生物、化學遷移和轉化內循環,溶解態和顆粒態物質水動力輸出3個邏輯模塊,涉及溶解無機氮( din ) 、磷酸鹽( po _ 4 - p ) 、浮游植物、浮游動物、有機碎屑和溶解有機態營養鹽6個狀態變量。

The main feed at this time consists of brine shrimp larvae , oyster eggs and diatoms spiruline , skeletonema costatum . however other zooplankton such as copepoda and rotifera can also be used . during the mysis stage the bodies of the fry become larger and so are able to ingest the nauplii of the brine shrimp along with spirulina and 糠蝦期幼蟲個體較大,已能攝食豐年蝦無節幼蟲,拌用螺旋藻,蝦苗丹喂飼,其存活率有意想不到的好,將螺旋藻與豐年蝦無節幼蟲,蝦苗丹等配合一起喂飼,其存活率高的原因,在于豐年蝦無節幼蟲亦能攝食螺旋藻蝦苗丹,可增加豐年蝦無節幼蟲的存活率,不僅能節省豐年蝦外,又能避免水質惡化不需要常換水。

This dissertation is about one - year ' s study of fuzhou ' s inner river in community ecology of zooplankton , which evaluated the water quality of this river through the analysis of the structure variation of its zooplankton community and combining with the physical and chemical indexes , then may give some suggestions to the rational and efficacious measures of fuzhou ' s inner river management 對福州內河進行為期一周年的浮游動物群落生態研究,以期利用浮游動物群落結構變化,結合理化指標對福州內河進行水質綜合評價,為福州內河合理、有效的治理提供基礎資料。

Studies by hargrave and geen estimated natural community graz - ing rates by measuring feeding rates of individual zooplankton species in the laboratory and then computing community grazing rates for field conditions using the known population density of grazers 由哈格雷夫( hargrave )和吉恩( geen )所進行的研究,對自然條件下的群落食草比例進行了估計,其手段是通過測量出實驗室內單獨的浮游動物種類的結食比例,然后利用已知的食草動物種群密度,計算出實地狀況下的群落食草比例。

In this paper , zooplankton communities , their species composition and indicator species in the east china sea and the yellow sea were examined with multivariate methods . in the southern part of the yellow sea , where was known as an important spawning ground of anchovy , the seasonal variations of zooplankton were studied in details with respect to species composition , abundance , biomass and vertical distribution . furthermore zooplankton indication of the yellow sea warm current ( yswc ) in winter was discussed 本論文用數理統計方法(包括:雙向指示種分析、多維定標序列分析、判別分析和多元回歸分析)對春、秋兩季東、黃海浮游動物群落進行了劃分、確定各群落的指示種;對南黃海浮游動物的種類組成、分布及其時空變化進行了研究,并與歷史資料進行了比較;并探討了黃海冷水團對某些浮游動物的意義,以及浮游動物對黃海暖流指示。

Results as following : in the east china sea and the yellow sea , zooplankton showed higher diversity in the low latitude and warm species occurred mainly in the south of 31 n , five communities were distinguished by twinspan method , based on data of species composition and environmental factors . they are : i ) yellow sea neritic community ( f ) with indicator species of labidocera euchaeta in autumn and centropages mcmurrichi in spring ; ii ) yellow sea central community ( hc ) with indicator species of themisto gracilipes , calanus sinicus and euphausia pacifica , the latter two species occurred only in autumn ; iii ) east china sea continental shelf mixed water community ( k ) with indicator species such as rhincalanus cornutus and pterosagitta draco which were confined in waters with high temperature and salinity , iv ) yellow sea and east china sea mixed water community ( he ) and v ) east china sea inshore mixed water community ( m ) 根據twinspan等多元分析結果,比較各組群的浮游動物種類組成和環境特征,可將東、黃海浮游動物群落分為5個,黃海沿岸群落( f ) ,指示種秋季為真刺唇角水蚤,春季為墨氏胸刺水蚤;黃海中部群落( hc ) ,指示種以細長腳蟲戎為主,秋季還有中華哲水蚤和太平洋磷蝦;東海外陸架高溫高鹽群落( k ) ,指示種為角錨哲水蚤、飛龍翼箭蟲等多種狹布型暖水種類;黃東海交匯區群落( he )和東海近岸混合群落( m ) ,兩群落包含多種生態類型種類,其中溫帶近岸低鹽種在he中較多,廣布性暖水種在m群落中較多。

In the periods of peak zooplankton abundance , that is , in the late spring and in the summer , haney recorded maximum daily com - munity grazing rates , for nutrient - poor lakes and bog lakes , respectively , of 6 . 6 percent and 114 percent of daily phytoplankton production 在浮游動物數量激增的高峰期,亦即在春季后期以及夏季,哈尼記錄了最大程度上的每日群落食草比率,對于營養物不充足的湖和沼澤湖而言,分別為每日浮游植物繁殖量的6 . 6 %和114 %

It was showed that carbon source bacteria could absorb was a more important factor than ( nh4 ) 2so4 and kh2po4 ; and higher ph , rich biomass of phytoplanktons and zooplanktons in water body also restrained the growth of heterotrophic bacteria 結果表明生物可利用的有機碳是主要的限制性營養因子,而氮源和磷源的影響較小;湖水的高ph以及豐富的藻類和浮游動物生物量也制約了異養細菌的生長。

High - latitude calcareous phytoplankton and zooplankton might share a similar fate , although their declines would come decades later because their shells are formed from calcite , the less soluble form of calcium carbonate 高緯地區的鈣質浮游植物和浮游動物可能有相似的命運,雖然它們受到影響的時間也許會晚數十年,因為鈣質浮游生物的外殼由方解石形成,這種碳酸鈣礦物結晶比較不容易溶解。

A water quality model of non - conservative substances , including nitrogen , phosphorus , phytoplankton and zooplankton is established , which takes into consideration the physical and biochemical processes related to nitrogen and phosphorus 摘要考慮了近岸海域影響氮、磷含量、時空分布的主要物理、生物化學過程,建立了膠州灣海域非保守物質(氮、磷)的水質預測模型。

In ground form , as well as zooplankton should be administered as feed . this can not only supplement a possible lack of plankton and lower costs , but also produce healthy and active shrimps . the ingredients of 當后期幼蟲開始進入底棲生活時,以混碎后的維仁蝦片與其他浮游生物喂飼,不但可以補足浮游生物的缺乏,節省成本外,就可孕育出健康活力的蝦苗。

Grazing of phytoplankton by zooplankton and suspension - feeding benthos is also considered a promising control agent , but this approach has many logistical problems and is a long way from the application stage 另一方面,利用大型海藻與微藻間的相生相克和營養競爭等作用在養殖區域內進行赤潮的防控被認為具有較強的理論和實踐意義。

During the mysis substages there is a gradual transition from phytoplankton to zooplankton . feed on : diatoms , animalcule such as a . salina , oyster eggs and larvae as well as on rotifers and nematodes 1在糠蝦期幼蟲的蛻變中,漸漸從攝食植物浮游生物轉變到動物浮游生物。餌料:藻類微生物如豐年蝦牡蠣卵輪蟲絲蟲類動物。

During the 20 - day expedition , 28 experts from 14 nations collected 1 , 000 individual specimens , including 120 species of fish , some new to science , and hundreds of species of zooplankton 在20天的探測中,來自14個國家的28位專家,采集了1000份標本,其中包括120種魚類,一些科學上的新物種,以及數百種浮游動物。
