Dr Stanbrook-Buyer found that dung beetles counter these negative effects.

斯坦布鲁克-拜尔博士发现蜣螂可以抵消这些负面影响。

In a recent paper in the journal Basic and Applied Ecology, Roisin Stanbrook-Buyer, an ecologist at Bethune-Cookman University in Florida, attempted to calculate an exact figure.

佛罗里达州贝塞斯达-库克曼大学的生态学家罗伊辛·斯坦布鲁克-拜耶在《基础与应用生态学》杂志最近发表的一篇论文中试图计算出一个确切的数字。

Among other things, says Dr Stanbrook-Buyer, dung beetles disrupt parasites from spreading in cow populations, help cycle nutrients in the soil and improve water quality by keeping faeces out of streams.

斯坦布鲁克-拜尔博士说， 除此之外，蜣螂还能阻止寄生虫在牛群中传播，帮助土壤中的养分循环， 并通过阻止粪便进入溪流来改善水质。
