异质物种和物种周转都可以影响异质嵌套性，多样性划分允许人们将β多样性中的周转和嵌套成分分开。因此，互补分析的metacompatibility嵌套和多样性分区允许在本地和区域尺度上的潜在变化的识别。本文研究了近60年来中国高原湖泊鱼类群落的变栖性、巢状性和α-、β-和γ-多样性的变化，这些变化是由于本地物种的大量丧失和外来物种的入侵造成的。我们发现，随着时间的推移，亚稳性嵌套性显著上升，由于本地物种的丧失而导致β多样性和γ多样性的丧失，以及由于非本地物种的增加而增加的α多样性。这一模式与自然生态系统中导致更大嵌套的选择性灭绝相矛盾，并表明人类引起的对metacompatibility的负面影响。然而，β-多样性划分表明，由于物种更替的湖泊之间的营业额的组成部分仍然贡献大于嵌套的组成部分，这表明，重要的是要避免设置保护优先级完全基于元生态嵌套理论，而是采取更全面的元生态方法来保护。
Metacommunity nestedness can be affected by both idiosyncratic species and species turnover, and diversity partitioning allows one to separate turnover and nested components within β-diversity. Thus, complimentary analysis of metacommunity nestedness and diversity partitioning allows for the identification of the underlying changes at both local and regional scales. We examined changes of fish assemblages in metacommunity nestedness and α-, β-, and γ-diversities resulting from the intense loss of native species and the invasion of nonnative species in Chinese highland lakes over the past 60 years. We found metacommunity nestedness rose markedly over time, following the loss of both β-and γ-diversity resulting from the loss of native species, and the increase of α diversity by the addition of nonnative species. This pattern is contradictory to the selective extinction leading to larger nestedness in natural ecosystems and indicates the human-induced negative effects on the metacommunity. However, β-diversity partitioning showed that the turnover component due to species replacement among lakes still contributes more than the nested component, suggesting the importance of avoiding setting conservation priorities based exclusively on metacommunity nestedness theory, but taking a more holistic metacommunity-approach to conservation instead.
