“…There is strong support for the observation that lianas preferentially impact certain ecological "guilds" of tree species such as late-successional/climax species (Campbell et al, 2015a(Campbell et al, , 2015bClark & Clark, 1990;Laurance et al, 2001;Schnitzer et al, 2000), although there is little evidence that this occurs at a species-specific level (Garrido-Perez & Burnham, 2010;Hegarty, 1991;Pérez-Salicrup, Sork, & Putz, 2001). The enhanced liana infestation rates on late-successional tree species is likely due to the advanced age (and thus time available for possible infestation) of these trees and certain character traits they possess (Hegarty, 1991;Schnitzer & Bongers, 2002).…”

“…Further, attributes of the liana community (abundance, size distribution class, and climbing guild) all respond to these influences. Nevertheless, liana abundance alone is often used as a proxy to infer likely liana impact (and future impact) on fragmented forests (e.g., Campbell et al, 2015aCampbell et al, , 2015bSchnitzer, Bongers, & Wright, 2011;Wright, 2010).…”

“…For instance, forest fragments (32 m 2 -100 ha) are estimated to possess 13%-75% less diversity than comparable nonfragmented forests (Haddad et al, 2015) with the majority of the lost diversity often the most iconic components, such as big trees and large mammals (Chiarello, 1999;Gibson et al, 2013;Laurance, 1997b;Laurance et al, 2000;Oliveira, Santos, & Tabarelli, 2008). In addition, forest fragmentation is also known to alter or degrade many beneficial ecological processes such as pollination and seed dispersal (Campbell, Laurance, & Magrach, 2015a;Campbell, Magrach, & Laurance, 2015b;Laurance et al, 2002;Magrach et al, 2014a;Peh, Lin, Luke, Foster, & Turner, 2014;Terborgh et al, 2001).…”

Closed‐canopy forests are being rapidly fragmented across much of the tropical world. Determining the impacts of fragmentation on ecological processes enables better forest management and improves species‐conservation outcomes. Lianas are an integral part of tropical forests but can have detrimental and potentially complex interactions with their host trees. These effects can include reduced tree growth and fecundity, elevated tree mortality, alterations in tree‐species composition, degradation of forest succession, and a substantial decline in forest carbon storage. We examined the individual impacts of fragmentation and edge effects (0–100‐m transect from edge to forest interior) on the liana community and liana–host tree interactions in rainforests of the Atherton Tableland in north Queensland, Australia. We compared the liana and tree community, the traits of liana‐infested trees, and determinants of the rates of tree infestation within five forest fragments (23–58 ha in area) and five nearby intact‐forest sites. Fragmented forests experienced considerable disturbance‐induced degradation at their edges, resulting in a significant increase in liana abundance. This effect penetrated to significantly greater depths in forest fragments than in intact forests. The composition of the liana community in terms of climbing guilds was significantly different between fragmented and intact forests, likely because forest edges had more small‐sized trees favoring particular liana guilds which preferentially use these for climbing trellises. Sites that had higher liana abundances also exhibited higher infestation rates of trees, as did sites with the largest lianas. However, large lianas were associated with low‐disturbance forest sites. Our study shows that edge disturbance of forest fragments significantly altered the abundance and community composition of lianas and their ecological relationships with trees, with liana impacts on trees being elevated in fragments relative to intact forests. Consequently, effective control of lianas in forest fragments requires management practices which directly focus on minimizing forest edge disturbance.
