东南亚生物多样性是全球优先保护的地区，因为其高度的多样性和特有性，加上一些最大程度的威胁。保护规划对于确保生物多样性和特有性热点地区得到必要的保护，以防止东南亚一些最多样化地区的森林砍伐、狩猎和其他形式的剥削至关重要，但这需要在许多情况下不存在的数据。越来越多的在线可用数据提供了开发物种分布准确模型的能力，并获得对区域多样性模式的新观点，并为规划和保护提供必要的基线数据。在这里，利用最好的可用信息，我绘制了2471种脊椎动物的分布范围图（鸟类、哺乳动物、爬行动物和两栖动物）和1198种植物物种，并探讨生物多样性的模式和保护的充分性。每个分类群表现出不同的多样性模式，并没有分类群提供了一个有效的替代多样性模式在不同的群体。我表明，大多数生物多样性热点都在保护区之外，10%至55%的地区至少有超过75%的最大物种未受保护。物种范围保护区的百分比也因类群而异，从最高的40%到爬行动物，平均只有13.5%的物种范围受到保护。此外，我的预测和世界自然保护联盟的多样性地图之间的比较差异很大，为所有类群检查，与世界自然保护联盟的热点覆盖了该地区的更大部分，并可能高估了许多物种的范围。需要进一步努力更好地保护多样性中心，将这些方法纳入区域保护规划可能会大大有助于提高保护的有效性。(C)2017爱思唯尔有限公司版权所有。
Southeast Asian biodiversity is a global priority for conservation, due to the high levels of diversity and endemistn, combined with some of the greatest levels of threat. Conservation planning is essential to ensure that hotspots of biodiversity and endemism have the protection needed to prevent deforestation, hunting and other forms of exploitation in some of the Southeast Asia's most diverse areas, yet this requires data which in many cases does not exist.Growing volumes of online available data provides the ability to develop accurate models of species distributions, and gain new perspectives on regional diversity patterns and provide essential baseline data for planning and conservation.Here, using the best available information I develop maps of the ranges of 2471 vertebrate (birds, mammals, reptiles and amphibians) and 1198 plant species, and explore patterns of biodiversity and the adequacy of protection. Each taxon shows different patterns of diversity, and no taxa provided an effective surrogate for diversity patterns in different groups. I show that for the majority of biodiversity hotspots fall outside protected areas, with between 10 and 55% of areas with at least >75% of the maximum number of species unprotected. The percentage of species ranges protected areas also varies by taxa, from a maximum of 40% to reptiles with a mean of only 13.5% of species ranges protected. Furthermore comparison between my predictions and IUCN maps of diversity differed greatly for all taxa examined, with IUCN hotspots covering a much larger portion of the region and potentially overestimating the ranges of many species. Further efforts are needed to better protect centres of diversity, and the inclusion of these methods into regional conservation planning may greatly assist in increasing the effectiveness of conservation.
