用海洋meiobenthic橈足類甲殼動物進行復原的基於微板的壽命周期毒性試驗的標準指南Age as one of the internal factors can affect the value of venturous revenue through acting on the checking results of the external factors ( e. g., predation pressure ), and thereby affect the optimal migrating strategies. therefore, the patterns for dvm vary with the change of the animal ' s age
作為內部狀態因子的年齡,因對外部因子(如捕食壓力)識別結果的影響而對風險收益值有較大的影響,從而影響橈足類垂直遷移的最佳策略,導致其遷移的形式隨年齡的變化而變化,一般來說,年齡越大的動物垂直遷移的時間越早、幅度越大; 3But the gut evacuation rates did not vary with the experimental temperature and body size. copepods usually performed feeding rhythms with maximum level at midnight and their feeding activities changed with the tide rhythms at the estuary area. in the laizhou bay, the daily grazing rate of the copepod population on phytoplankton was 20. 81 ? 98. 35 % of the primary production and 2. 53 ? 6. 36 % of the phytoplankton standing stock in summer
現場測得的橈足類攝食率結果表明,在萊州灣,夏季橈足類群體的日攝食量占初級生產力的20 . 81 ? 98 . 35 % ,占浮游植物現存量的2 . 53 ? 6 . 36 % ,濰河口,河口外浮遊動物優勢種群體的日攝食量占初級生產力的32 . 28 % ,占浮游植物現存量的14 . 12 % ,河口內對初級生產力的攝食壓力< 3 % ,日攝食量小於浮游植物現存量的1 % 。The dvm behavior of the copepod is controlled by multi - factors. the diversified migrating patterns show that copepod is the active decision - maker, which can achieve the optimal food intake during its avoiding predation by performing the normal dvm ; 2
足類的晝夜垂直遷移行為是由多因子控制的,其遷移模式的多樣性表明,橈足類是主動的決策者,通過識別環境因子的變化,橈足類藉助于常規的晝夜垂直遷移在逃避捕食壓力的同時能夠實現最優的食物攝取量; 2In the summer stratified water column, the deeper the maximum depth of food distribution is, the stronger the dvm is performed ; the increase of the gradient of temperature in the thermocline layer can decrease the magnitude of the dvm and form the thermal barricade to the copepod ; the effects of the predation pressure on dvm is complex. on the one hand, the variations in the distribution depth of the predation pressure vs. the thermocline layer or the depth of the maximum food can modify the dvm patterns of the copepod. on the other hand, different predation pressure induces different dvm patterns
在夏季分層水體中,食物的最大分佈深度越大,動物向下遷移的幅度也越大;溫躍層的溫度梯度增大可以減小動物遷移的幅度,成為橈足類垂直遷移的溫度屏障;捕食壓力對垂直遷移的影響較復雜,一方面,捕食壓力的分佈深度與溫躍層或食物峰值的相對位置的變化能夠改變橈足類垂直遷移的模式,另一方面,捕食壓力強度不同,橈足類垂直遷移的幅度也不同,捕食壓力越大,遷移的幅度越大,當捕食壓力增加到一定程度,橈足類停止向上的遷移,大部分時間呆在水體深層,可能進入捕食壓力引起的「滯育」狀態。Finally, he had the plan to support up to 20 very good copepodologists from developing countries
最後,將修更計劃補助多達二十位來自開發中國家的傑出橈足類動物學者。Using the seawater dilution technique, microzooplankion grazing impact on phytoplankton was experimentally studied in xiamen prawn cultivated pond and xiamen west harbor. copepod gut pigment contents were measured and the feeding of acartia pacme was studied. the grazing pressure of microzooplankton on phytoplankton and its excretion of nitrogen derived from phytoplankton were estimated
2000 - 2002年,在廈門杏林蝦池和廈門西港採用海水稀釋法進行了微型浮遊動物對浮游植物攝食壓力的研究,測定了廈門西港不同體長組浮遊橈足類的腸色素並在實驗室進行了太平洋紡錘水蚤攝食實驗。There were significant correlation between md and abundance of nematode ( p < 0. 05 ) and weak negative correlation among water depth and numbers of meiofauna, nematode and copepods ( p > 0. 05 ). biomass spectra, the biomass distribution over a sequence of the body size intervals, provide dynamic information about the relationships among components in ecosystem
小型底棲動物、海洋線蟲和橈足類的豐度和生物量與環境因子進行pearson相關性分析,結果顯示海洋線蟲的豐度與沉積物的中值粒徑相關性顯著( p 0 . 05 ) 。分享友人
