河口桡足动物在其身体上自然携带着多种细菌。桡足类的细菌群落组成(BCC)在饲喂不同种类的无性系藻类时仍保持非常保守的状态,说明食性对桡足类的细菌群落组成影响不大。然而,在xenic藻类处理中,即使使用相同的细菌来源接种藻类,桡足类相关的BCC也因每种藻类而异。此外,在同一地点不同时间捕获的饥饿桡足类动物的BCC也有显著差异。因此,藻类组成和桡足动物生活史可以调节与桡足动物相关的BCC,藻类组成和桡足动物起源的时空变化会改变细菌-桡足动物的相互作用。
The estuarine copepodAcartia tonsanaturally carried diverse strains of bacteria on its body. The bacterial community composition (BCC) remained very conservative even when the copepod was fed different axenic algal species, indicating that the foodper sedid not much affect BCC associated with the copepod. In xenic algal treatments, however, copepod-associated BCC differed with each alga fed, even though the same bacterial source was used to inoculate the algae. In addition, starved copepods taken at the same location but at different times significantly differed in their BCC. Algal species composition and copepod life history therefore serve to regulate BCC associated with copepods, and spatial and temporal variations in algal species composition and copepod origin would alter bacteria–copepod interactions.
