全球生物多样性的丧失可以归因于许多威胁。虽然先驱研究调查了它们的相对重要性，但大多数研究局限于特定的地理区域和/或分类群体，只考虑威胁的一小部分，尽管它们经常相互作用，但通常是孤立的。在这里，我们调查了导致世界各地岛屿物种减少的11个主要威胁。我们应用了一种创新的网络分析方法来理清15个岛屿地区脊椎动物、无脊椎动物和植物受到的多种威胁之间的关联。生物入侵、野生动物开发和耕作，无论是单独的还是联合的，都被发现是岛屿上物种灭绝和衰落的三个最重要的驱动因素。具体地说，野生动物的开发和养殖在很大程度上与受威胁的植物和陆生脊椎动物的减少有关，而生物入侵主要威胁无脊椎动物和淡水鱼。此外，与太平洋和大西洋岛屿地区的生物入侵相比，印度洋和亚洲沿海附近的生物多样性主要受到野生动物开发和种植的影响。我们强调了不同规模的威胁的具体关联，表明对每个威胁的孤立分析可能不足以制定有效的保护政策和管理。
The global loss of biodiversity can be attributed to numerous threats. While pioneer studies have investigated their relative importance, the majority of those studies are restricted to specific geographic regions and/or taxonomic groups and only consider a small subset of threats, generally in isolation despite their frequent interaction. Here, we investigated 11 major threats responsible for species decline on islands worldwide. We applied an innovative method of network analyses to disentangle the associations of multiple threats on vertebrates, invertebrates, and plants in 15 insular regions. Biological invasions, wildlife exploitation, and cultivation, either alone or in association, were found to be the three most important drivers of species extinction and decline on islands. Specifically, wildlife exploitation and cultivation are largely associated with the decline of threatened plants and terrestrial vertebrates, whereas biological invasions mostly threaten invertebrates and freshwater fish. Furthermore, biodiversity in the Indian Ocean and near the Asian coasts is mostly affected by wildlife exploitation and cultivation compared to biological invasions in the Pacific and Atlantic insular regions. We highlighted specific associations of threats at different scales, showing that the analysis of each threat in isolation might be inadequate for developing effective conservation policies and managements.
