Vascular epiphyte global distributions

Aim: 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. Location: Global. Time period: Present. Major taxa studied: Tracheophyta. Methods: Using a comprehensive epiphyte species list (EpiList 1.0), and distribution information for 27,850 epiphyte species derived from numerous literature sources, we describe the global biogeography of epiphytes. We used generalized linear mixed effects models to assess the relationship between epiphytic and terrestrial...研究目的：维管附生植物是湿润热带森林中广泛分布的类群，对局域和区域植物多样性贡献显著。尽管部分附生植物的基础分布格局已得到较为充分的研究，但目前针对限制其全球分布的驱动因素的探索仍相对匮乏。本研究量化了附生植物对维管植物全球多样性梯度及多样性中心的显著贡献，并探讨附生植物与陆生植物在响应现代与历史环境变量方面是否存在差异。 研究范围：全球。 研究时段：现代。 研究类群：维管植物（Tracheophyta）。 研究方法：本研究依托综合附生植物物种名录《EpiList 1.0》，以及从大量文献来源获取的27850种附生植物的分布数据，阐明了附生植物的全球生物地理学格局。我们采用广义线性混合效应模型，评估附生植物与陆生植物之间的关联……
