研究表明，非本地大型食草动物对植物群落的影响与本地植物没有区别，这挑战了它们对生态系统破坏更大的假设。 Study shows non-native large herbivores have indistinguishable effects on plant communities as natives, challenging the assumption they damage ecosystems more.

发表在《科学》杂志上的新研究表明，为了保护植物物种而以非本地动物为由来消灭动物可能是一种有缺陷的做法，会花费数百万美元，并导致数百万健康野生动物被屠杀。 New research published in Science suggests that eradicating animals on the basis of them not being native to protect plant species can be a flawed practice that costs millions of dollars and results in the slaughter of millions of healthy wild animals. 研究发现，引进的大型食草动物和本地大型食草动物（也称为巨型动物）对植物群落的影响没有区别。 The study found that introduced large herbivores and native large herbivores, also known as megafauna, have indistinguishable effects on plant communities. 这些发现挑战了非本地物种比本地物种对生态系统的破坏更大的普遍假设。 These findings challenge the common assumption that non-native species damage ecosystems more than native species.
