According to the invasion criterion, stable coexistence requires that all species in a community increase in abundance when rare, which occurs when stabilizing mechanisms cause intraspecific competition to be stronger than interspecific competition. This simple principle has traditionally been applied to tests of local coexistence in a narrow range of ecological systems. However, new theory founded on the invasion criterion is emerging across ecological fields ranging from eco-evolutionary dynamics to global change to macroecology. Concurrently, straightforward methods for testing the invasion criterion have been proposed, but remain underused. Here, we identify the invasion criterion as a common thread linking emerging ecological theory, and we bring this theory together with the methods that can be used to test it.
根据入侵准则，稳定共存要求当稀有物种增加时，群落中的所有物种都增加，这发生在稳定机制导致种内竞争比种间竞争更强的时候。这一简单原则传统上适用于在狭窄的生态系统范围内对局部共存的测试。然而，基于入侵准则的新理论正在从生态进化动力学到全球变化到宏观生态学等各个生态领域中涌现出来。同时，提出了测试入侵准则的简单方法，但仍未得到广泛应用。在这里，我们将入侵准则确定为将新兴生态理论联系起来的共同线索，我们将这一理论与可以用来检验它的方法结合起来。
