interspecies competition 中文意思是什麼
-
In this dissertation, the interactive system of delphastus catalinae ( horn ), its preys and competitor was studied, including comparison between alternative preys and natural prey consumed by d. catalinae ; the system of d. catalinae and its preys ; morphology comparison between d. catalinae and its competitor serangium japonicum chapin ; biology, ecology and predation of s. japonicum ; and also the interspecies competition between d. catalinae and s. japonicum. 1. besides whitefly pests, d. catalinae could also feed on two species of alternative preys : tetranychus nr
Fijiensis和桃蚜myzuspersicae （ sulzer ） ，並在實驗室條件下，以自然獵物煙粉虱bemisiatabaci為對照，研究了替代獵物對小黑瓢蟲的發育、存活、繁殖及對實驗種群增長的綜合影響，結果表明： （ 1 ）小黑瓢蟲以蚜蟲為獵物時，成蟲不會產卵，但可延長成蟲的壽命；以紅蜘蛛為獵物時，成蟲可產卵並可完成整個世代。 -
These are main problems of eutrophication. at first we select algae which grow under different level of nutrition ( or different development phase in the process of eutrophication ), domesticate, selecte seed, and culture algae at the lab, and then we obtain dependence of each algae on nutrition and understand information of eco - breadth of nutrition of supplied alga through pure culture under different concentration of nutrition. we find out resource utilization, competition between interspecies and confirm the quantity - effec t relationship between succession of species and nutrition through mixed culture
本文首先選取在不同營養環境下（或富營養化過程的不同發展階段）生長的藻類物種，在實驗室內進行馴化、選種與純化培養；然後通過不同營養水平的純藻培養實驗，獲取不同藻種生長過程對營養物質的依賴行為，從而可以了解每一供試藻種的營養物生態幅信息；再通過對應培養濃度的混合培養試驗，以期揭示生物種群間的資源利用與競爭行為，並可進一步確定生物種群的演替與環境營養物之間的量效關系。
