摘要: We studied three different size classes of liana abundance representing proxies for life stages and aimed to identify the sequence ecological filters that have led current patterns abundance. tested relationship between vegetation structure (including antagonistic support types) soil texture on abundance, using 40 plots (1 0.25 ha) set at least 1 km apart, distributed over 64 km2 in a Central Amazonian terra firme forest. Three types were considered: palms, thin trees an index structure. Liana responded hierarchically filters: larger progressively less associated with environmental variables, while aspects related individual classes. This hierarchical pattern suggests selection mechanisms change throughout cycles. Our results show is important predictor mesoscale highlights importance considering spatial studies tropical communities. Abstract Portuguese available http://www.blackwell-synergy.com/loi/btp.
