I assessed the role of low vegetation (plants ca 1 yr old and ≤50 cm tall) as a biotic facilitator or barrier in the recruitment of different growth forms and species in primary forests, secondary forests, and old‐fields (abandoned pastures) in southeastern Mexico. I removed by hand all plants (≤100 cm tall, including roots) and litter from 20, 0.25 m2 plots in each habitat. For 1 yr, I counted the number of plant species (5–50 cm tall) recruited, grouped them into different growth forms, and compared them to undisturbed control plots. Prior to manipulation, the standing density of trees and lianas was highest in primary and secondary forests. Shrubs were more abundant in secondary forests, whereas herbs, epiphytes, and hemi‐epiphytes were more abundant in old‐fields. Herbaceous plants appeared as important components of the community in all habitats. The removal of low vegetation increased total plant recruitment in all habitats. Considering each growth form, the absence of vegetation increased recruitment in primary forests for herbs, in secondary forests for epiphytes and hemi‐epiphytes, in old‐fields for trees, and for lianas in primary forests and old‐fields. In vegetation removal plots, recruitment of species was greater in pastures, lower in secondary forest, and similar in primary forest with respect to control plots. Depending on habitat type, species, and growth form, the presence of low vegetation may act as a recruitment barrier or facilitator for different species, affecting plant community structure, diversity, and composition in different habitats.

“…Significant relations between the contribution of a species to nestedness (n i ) and abundance and traits of lianas and trees. Nevertheless, most lianas climb on the most suitable trees in the neighbourhood of their initial rooting point (Vleut & P erez-Salicrup 2005;Garrido-Perez & Burnham 2010;Roeder et al 2015). Liana and tree abundances were ln-transformed prior to statistical analyses.…”

Species traits and abundance influence the organization of liana–tree antagonistic interaction

et al. 2017

The interaction among species can be influenced by neutral processes, in which more abundant species have high effect on the structure of interaction, or can be influenced by trait matching. Despite both variables (abundance and species traits) influencing the interaction of species in mutualistic networks, few studies showed their importance in antagonistic networks. Here, we posed the question: what are the main predictors of the liana-tree interactions: species abundance, biological traits or both? In a savanna woodland fragment in south-eastern Brazil, we sampled lianas and trees in 1 ha, where we recorded the abundance, maximum height and bark roughness of tree species, as well as abundance, maximum diameter and climbing system of liana species. For each species, we calculated their contribution to nestedness (n i ), which is a measure of network structure, and performed simple linear regressions between n i and abundance and species traits. Abundant species contribute more to n i than rare species, indicating that neutral processes affect interactions between lianas and trees, probably because lianas are opportunistic and climb trees in their neighbourhood. The only trait related to n i was tree height, which can indicate that light availability can have a considerable role on network structure between both growth forms. Therefore, the importance of species abundance and tree height can be related to opportunism of lianas on climbing the most suitable tree in their neighbourhood.

“…The abundance of lianas in all size classes was negatively related to the density of palms, corroborating our hypothesis that palms do not represent suitable supports for liana climbing and could decrease the availability of light to other plants. Palm architecture may allow liana occupation (Vleut & Pérez‐Salicrup 2005), but emerging leaves from the apical meristem disarrange lianas and may cut them. Frond shedding also leads to liana detachment (Putz 1980).…”

“…Lianas' abilities to climb into the canopy is facilitated if the branches or stems of understory trees are between 0.5 and 10 cm diam (Putz & Holbrook 1991, Balfour & Bond 1993). Palms can displace or damage lianas by growth of new palm leaves which can cut liana stems (Vleut & Pérez‐Salicrup 2005), by liana seedlings being buried under fallen palm leaves or destroyed by increasing abundance of insects and pathogens under palm leaf litter (Putz 1980, Denslow et al . 1991, Harms et al .…”

Liana Abundance Patterns: The Role of Ecological Filters during Development

2010

We studied three different size classes of liana abundance representing proxies for three different life stages and aimed to identify the sequence of ecological filters that have led to current patterns of liana abundance. We tested the relationship between vegetation structure (including antagonistic support types) and soil texture on liana abundance, using 40 plots (1 and 0.25 ha) set at least 1 km apart, and distributed over 64 km 2 in a Central Amazonian terra firme forest. Three support types were considered: palms, thin trees and an index of vegetation structure. Liana size classes responded hierarchically to ecological filters: larger size classes were progressively less associated with the environmental variables, while different aspects of vegetation structure were related to individual size classes. This hierarchical pattern suggests that selection mechanisms change throughout liana life cycles. Our results show that vegetation structure is an important predictor of liana abundance at a mesoscale and highlights the importance of considering the spatial structure in studies of tropical liana communities.
