其原理在于，大量的这种真菌意味着当地有大量的哺乳动物粪便，也同时反映了一个大型的哺乳动物群体。

They reasoned that more fungal spores meant more dung, which in turn reflected a larger population of roaming mammals.

微生物是包括细菌、病毒、真菌以及一些小型的原生生物等在内的一大类生物群体，它个体微小，却与人类密切相关。

Microorganism is a large biological population, including bacteria, virus, fungi and some small protist. It is tiny but closely related with human beings.

我曾见到小的群体在其它任何地方的高密度蚜群被真菌杀死的同时差不多也被杀死了。

I have seen small population almost wiped out by fungus at the same time as dense aphis populations elsewhere.
