  abstract = {{D}espite a long tradition in ecology of studying tree species assembly and its potential drivers in tropical forest communities, little information exists with respect to lianas (woody climbers), the second most abundant life form of woody plants in tropical forests. {L}ianas influence forest diversity and stability and provide critical resources for forest fauna. {U}sing a unique dataset of a 30-ha plot in {T}hailand, where tree and liana individuals were fully mapped, we investigated the degree to which local species assemblages of trees and lianas of different size classes (i.e., seedlings, established individuals, and large individuals) are related to local environmental conditions. {W}e asked (1) {W}hat are the spatial patterns and environmental drivers of local tree and liana species assemblages? (2) {H}ow do such patterns and drivers differ among size classes? (3) {W}hich species associate with these assemblages? {L}ocal assemblages of established trees showed substantial structuring by environmental variables, whereas we found only weakly structured assemblages of tree seedlings, large trees, and lianas of all size classes. {O}ur results indicated that the biotic and abiotic drivers of local species assemblages differed strongly between tree and liana communities and across size classes. {S}pecies assemblages of trees were mainly driven by soil nutrients, leading to patchy assemblages associated with high base saturation ({A}lfisols) and assemblages associated with lower levels of base saturation and higher aluminum ({U}ltisols), whereas tree seedling assemblages were only weakly structured by riparian zones. {I}n contrast, species assemblages of established and large lianas were primarily associated with forest canopy structure, separating low-canopy forests from high-canopy forests, whereas soil nutrients were the only factors associated with liana seedling assemblages. {T}he weak environmental structuring of tree seedlings and large trees suggests that other mechanisms, such as stochastic disturbances, competition for space, or animal seed dispersal, may play an important role in structuring tree communities in this seasonal tropical forest. {T}he weak patterns observed in liana communities across all life stages raise questions about the underlying mechanisms of liana community assembly, and further research should focus on liana niches, their dispersal mechanisms, and host tree relations.},
