自然资源保护主义者通常认为岛上的啮齿动物主要是指入侵的有害物种，它们对全球岛屿造成了相当大的生态破坏。然而，在世界上近2300种啮齿动物中，几乎有五分之一是岛屿特有的，岛屿啮齿动物的灭绝和濒危率很高。在西印度群岛和东南亚物种丰富的群岛，第四纪物种灭绝和当前威胁的速度尤其高。啮齿动物的地方病在大型或偏远的海洋岛屿上达到了最惊人的水平，如马达加斯加、加勒比海、琉球群岛、大洋菲律宾、苏拉威西、加拉帕戈斯群岛和所罗门群岛，以及非常大的陆桥岛屿，特别是新几内亚。虽然过去和现在的保护工作主要集中在有魅力的哺乳动物（如鸟类和大型哺乳动物）上，但在不久的将来，专门针对不那么引人注目的动物（如岛屿啮齿动物）的努力可能是必要的，以阻止大量灭绝。(C) 2007 Elsevier Ltd和INQUA。版权所有。
Rodents on islands are usually thought of by conservationists mainly in reference to invasive pest species, which have wrought considerable ecological damage on islands around the globe. However, almost one in five of the world's nearly 2300 rodent species is an island endemic, and insular rodents suffer from high rates of extinction and endangerment. Rates of Quaternary extinction and current threat are especially high in the West Indies and the species-rich archipelagos of Southeast Asia. Rodent endemism reaches its most striking levels on large or remote oceanic islands, such as Madagascar, the Caribbean, the Ryukyu Islands, the oceanic Philippines, Sulawesi, the Galapagos, and the Solomon Islands, as well as on very large land-bridge islands, especially New Guinea. While conservation efforts in the past and present have focused mainly on charismatic mammals (such as birds and large mammals), efforts specifically targeted toward less conspicuous animals (such as insular rodents) may be necessary to stem large numbers of extinctions in the near future.
