As they report in Ecology Letters, he and his colleagues set up eight “mesocosms”, each containing five beanstalks.

《学通讯》报道，约翰逊及其同事建立的八个“中型实验系”各包含五株豆茎。每。

The medaka that were in the mesocosms treated with imidacloprid were all, absolutely all 100 percent of the fish, were contaminated with protozoan parasites.

在接受吡虫啉处理的中系中，所有的都被原动物寄虫污染了。

The day I explained the results of the first year mesocosm studies to the whole group and to the faculty, at the end he just couldn't understand the results himself.

当我向整个团队和教员解释第一年中系研究的时，最后他自己都无法理解这些。

Then, four days from the end, one of the 40-micron meshes in each mesocosm was rotated to sever any hyphae that had penetrated it, and the central plant was then infested with aphids.

到了实验束前四天，研究人员在每个系统中都旋转了一个40微米网筛，切断了所有穿过筛孔的真菌菌丝，不久位于中央的那株蚕豆就受到了大批蚜虫的侵扰。
