Vascular epiphytes are ubiquitous components of wet tropical forests where they contribute substantially to local and regional plant diversity. While some basic epiphyte distribution patterns are relatively well studied, little effort has been made to understand the drivers responsible for constraining their global distribution. This study quantifies the substantial contribution of epiphytes to global gradients and centres of vascular plant diversity and explores whether epiphytes vary from terrestrial plants in relation to contemporary and historical environmental variables.

血管附生植物对全球植物多样性中心的贡献不成比例

维管附生植物是潮湿热带森林中无处不在的组成部分，它们对当地和区域的植物多样性做出了重大贡献。虽然对一些基本的附生植物分布模式进行了相对深入的研究，但很少有人努力了解负责限制其全球分布的驱动因素。这项研究量化了附生植物对全球梯度和维管植物多样性中心的重大贡献，并探讨附生植物是否与陆生植物不同，与当代和历史环境变量有关。
