摘要
The high tropical Andes host one of the richest alpine floras of the world, with exceptionally high levels of endemism and turnover rates. Yet, little is known about the patterns and processes that structure altitudinal and latitudinal variation in plant community 多樣性. Herein we present the first continental-scale comparative study of plant community 多樣性 on summits of the tropical Andes. Data were obtained from 792 permanent vegetation plots (1m2) within 50 summits, distributed along a 4200 km transect; summit elevations ranged between 3220 and 5498 m.a.s.l. We analyzed the plant community data to assess: (1) differences in 物種 abundance patterns in summits across the region, (2) the role of geographic distance in explaining floristic similarity, and (3) the importance of altitudinal and la
