“…Therefore, the RII is useful to quantify facilitation or competition among a group of interacting species, where RII values close to 1 represent positive effects (facilitation) and -1 negative effects (competition). TBE structures are inhabited by animals from 97 families belonging to 15 classes (Table 2), including the description of new species (Disney 1999;Vera and Schapheer 2018). Most of the reported animals are invertebrates that inhabit litter and soil (90 families).…”

Background: Secondary foundation species (FS) are organisms that inhabit ecosystems structurally defined by a primary foundation species, providing additional structure to habitats and communities. Trash-basket epiphytes (TBE) are secondary FS that enhance arboreal soil accumulation, providing shelter to animals, and rooting sites for plants. While their importance may vary across biomes, TBE have been overlooked as drivers of biodiversity and ecosystem functions. Here, we discuss the prevalence of TBE across biomes, their effects on biodiversity and ecosystem functions, and future research directions. Methods: We performed a systematic literature review of articles, books and theses and collated and synthesised information about the taxonomic distribution of TBE, their effects on ecosystem functions, and reports of plant-animal and plant-plant interactions. Then, we analysed the global distribution of TBE using a generalized linear model and summarised two studies to assess their effects on soil invertebrates. Results: We identified 120 publications describing 209 species of TBE. Most TBE belong to Araceae (43%), Polypodiaceae (23%), and Orchidaceae (14%) and occur in all tropical and southern temperate forests. TBE richness peaks in the South-American Pacific mangroves, Eastern Cordillera Real, and the Napo moist forests. TBE effects on ecosystem functions include arboreal soil accumulation, water retention and temperature regulation in the canopy, and nutrient leaching through stem-flow. TBE provide shelter to species in more than 97 animal families, including from invertebrates to mammals, while 72 vascular plants have been reported to root in arboreal soil of TBE. Conclusions: TBE are a compelling group of model organisms that can be used to study ecological processes such as facilitation cascades, niche construction, extended phenotypes, or the effects of secondary FS on biodiversity and ecosystem functioning. TBE should also be included in forest management plans to enhance the availability of microhabitats in the canopy supporting its associated flora and fauna.

“…The lack of large trees in secondgrowth or degraded forest stands can limit the long-term viability of local populations of F. bicolor and its ecological role in the forest. This epiphyte is associated with 50% of arboreal soils and epiphytic green tissues (Díaz et al 2010), enhancing the cover of vascular epiphytes (Ortega-Solís et al 2017), and providing habitat to invertebrates living along the vertical profile of trees (Ortega-Solís et al 2017, Vera & Schapheer 2018. Although the conservation status of F. bicolor has not been assessed in the current IUCN Red List, monitoring of population trends is recommended (Zizka et al 2009).…”

Biogeosciences and Forestry Biogeosciences and Forestry The importance of tree species and size for the epiphytic bromeliad Fascicularia bicolor in a South-American temperate rainforest (Chile) Gabriel Ortega-Solís (1-5) , Iván Díaz (2) , Daniela Mellado-Mansilla (2) , Ricardo Moreno-González (3) , Javier Godoy (2) , Horacio Samaniego (4) Bromeliads are a numerous family of vascular epiphytes, though only one epiphytic species inhabits South-American temperate rainforests: the endemic Fascicularia bicolor. This bromeliad is an important driver of canopy biodiversity, but attributes of its hosts are mostly unknown. Here we report (i) the tree species colonized by F. bicolor, (ii) the relationship between tree size and presence of F. bicolor and (iii) the relation between tree size and the number of mats of F. bicolor inhabiting each colonized tree. We sampled 231 trees in seven forest plots recording their species, diameter, heights, and the number of F. bicolor mats growing on them. The dataset was analyzed with a zero-inflated model to relate host tree attributes with F. bicolor occurrence and abundance in a single statistical approach. The occurrence and abundance of F. bicolor depend on host-species identity and diameter. F. bicolor colonization in slow-growing trees started at smaller DBH than that required for other tree species. Nonetheless, the overall occurrence of F. bicolor relies on large trees above 50 cm DBH for most host species. The number of mats occurring on each colonized tree depends on the interaction between tree height and species suggesting the importance of space available for colonization along the tree-trunk, and differential effects due to species' traits. Currently, large trees and old-growth forests are scarce within the distribution range of F. bicolor, which could seriously affect the long-term conservation of this endemic epiphyte, along with the canopy properties and species associated with it.
