捕食壓力 的英文怎麼說
中文拼音 [bǔshíyālì]
捕食壓力
英文
predator pressure-
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。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； 3The 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。分享友人
