“…suppression mortality [2,15]). However, lianas typically reach the canopy at small diameters (>50% of lianas ≥2 cm in diameter are in the canopy) and they have the structural plasticity to grow laterally from their rooting point to overtop various host trees, not just their immediate neighbours [15,20], possibly reducing the effect of forest thinning on liana mortality rates [21]. If lianas are less susceptible to post-disturbance forest thinning than trees, then this could explain the apparent competitive advantage of lianas in recently disturbed forests [2,18].…”

Lianas are major contributors to tropical forest dynamics, yet we know little about their mortality. Using overlapping censuses of the lianas and trees across a 50 ha stand of moist tropical forest, we contrasted community-wide patterns of liana mortality with relatively well-studied patterns of tree mortality to quantify patterns of liana death and identify contributing factors. Liana mortality rates were 172% higher than tree mortality rates, but species-level mortality rates of lianas were similar to trees with ‘fast’ life-history strategies and both growth forms exhibited similar spatial and size-dependent patterns. The mortality rates of liana saplings (<2.1 cm in diameter), which represent about 50% of liana individuals, decreased with increasing disturbance severity and remained consistently low during post-disturbance stand thinning. In contrast, larger liana individuals and trees of all sizes had elevated mortality rates in response to disturbance and their mortality rates decreased over time since disturbance. Within undisturbed forest patches, liana mortality rates increased with increasing soil fertility in a manner similar to trees. The distinct responses of liana saplings to disturbance appeared to distinguish liana mortality from that of trees, whereas similarities in their patterns of death suggest that there are common drivers of woody plant mortality.

“…In comparison with freestanding trees, lianas can grow rapidly by allocating more carbon to stem elongation and leaf expansion than to mechanical support (Putz, 1983; Schnitzer, 2005). Once reaching the upper canopy, lianas increase shading and weight stress on their hosts, and thus, they impact forest dynamics and carbon balance of the forest stand (Medina‐Vega et al, 2022; van der Heijden & Phillips, 2009). Many studies, especially those from Neotropical forests, report that liana abundance and their impact on forest dynamics are increasing in recent decades (Laurance et al, 2014; Phillips et al, 2002; Schnitzer et al, 2012, 2021; Schnitzer & Bongers, 2011; Wright et al, 2004).…”

The ecology of lianas (woody vines) is important in forest dynamics, especially in seasonal tropical forests, where their diversity and abundance are typically high (Gentry, 1991). In comparison with freestanding trees, lianas can grow rapidly by allocating more carbon to stem elongation and leaf expansion than to mechanical support (Putz, 1983;Schnitzer, 2005). Once reaching the upper canopy, lianas increase shading and weight stress on their hosts, and thus, they impact forest dynamics and carbon balance of the forest stand (Medina-Vega et al., 2022;van der Heijden & Phillips, 2009).

“…Generally, studies of plant species interactions commonly focus on similar growth forms, which are assumed to compete intensely for shared resources. For example, in forests, studies of species interactions are typically focused on tree-tree competition; however, many trees in subtropical and tropical forests also suffer from competition from other non-tree plant groups, such as lianas (Medina-Vega et al, 2022).…”

1. Tree-tree competition has been widely studied as a mechanism responsible for maintaining forest plant species diversity. Other common plant types, such as lianas, may influence tree species competition. Previous studies reported the negative effects of lianas on trees; however, variation in susceptibility to lianas among tree species and the species-specificity of liana species for tree hosts remain unclear. If lianas have species-specific interactions with trees, based either on tree or liana species identity, then lianas may influence tree-tree interactions by altering tree species-specific competitiveness.2. We surveyed 5676 lianas (DBH ≥ 0.5 cm) and 61,538 trees (DBH ≥ 1 cm) in a 12ha subtropical secondary forest plot to assess liana-tree interactions. We tested variation among the 20 most common tree species in their susceptibility to lianas, including whether light-demanding and shade-tolerant tree species differed. We quantified liana-tree network structure and evaluated the specificity between the 20 most common tree species and the 15 most common liana species. We expected that: (1) tree species would vary in their susceptibility to lianas, and the extent of this variation would be predicted by tree shade-tolerance; and (2) liana species would have distinct species-specific interactions with host trees.3. Tree species differed greatly in their susceptibility to lianas, with some tree species accumulating many more lianas than others. Light-demanding tree species particularly had greater susceptibility to lianas than shade-tolerant tree species.Both the liana-tree network structure and the interaction intensity between the 15 liana species and 20 tree species showed distinct specialization of liana-tree interactions.4. Synthesis. Variation in trees species' susceptibility to lianas implies that lianas may alter tree species-specific competitive abilities by disproportionately affecting some tree species more than others. In contrast to studies in neotropical forests, light-demanding tree species were more susceptible to lianas than shade-tolerant | 1657
