  6. 3. food, temperature and predation pressure directly act on the value of venturous revenue and are major environmental factors affecting dvm of the copepod

    食物、溫度和捕食壓力直接影響風險收益值的大小，是影響橈足類垂直遷移的主要環境因子。
  7. A model is developed to analyze the tradeoff between benefits and costs involved in the strategies for the normal dvm of copepod. the venturous revenue is used as the criterion for this optimal tradeoff. it is a function of the environmental factors and the age of copepod

  8. During vertical migration, the copepod is assumed to instantaneously check the variations of the environmental parameters and can thereby make the optimal behavioral strategy to maximize the value of venturous revenue, i. e., taking up as much food as possible at as less cost of mortality as possible

  9. But 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 % 。
  10. Copepod feeding activities and their grazing impacts on the phytoplankton biomass and primary production were studies by the gut fluorescence method in the coastal waters of china ( the bohai sea, yellow sea, east china sea, laizhou bay and weihe estuary ) and the southern ocean ( the prydz bay and its adjacent area )

    本文利用腸道色素法，對我國近海（渤海、黃海、東海、萊州灣、濰河口）和南大洋（普里茲灣及鄰近海域）浮遊橈足類在自然海區的攝食狀況及其對浮游植物及初級生產力的攝食壓力進行了研究。
  11. 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； 2
  12. In 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。
  13. 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。
