Data from: Epiphyll specialization for leaf and forest successional stages in a tropical lowland rainforest

We used epiphylls on rainforest leaves to study the importance of leaf- and forest-scale succession in determining biodiversity patterns by characterizing community change with leaf age in gaps and closed-forest habitats. We asked: 1. Do epiphylls show specialization for leaf and forest successional stages? 2. Can early and late-successional epiphyllous species be recognized at these two scales? 3. How do epiphyll presence, species richness, and cover change with leaf and forest successional stages? Location Barro Colorado Island, Panama. Methods Data were collected from 420 leaves, in three age groups and at two heights on shrubs in gaps and closed forest. We calculated turnover and nestedness components of dissimilarity to evaluate the importance of species replacement or accumulation during leaf and forest succession...

The study was done in the mangroves of Bocas del Toro Province, Panama, in September 2016 and, July, May and August 2017. Bryophytes were collected from prop or stilt roots of mangroves, the mid-lower part of the trunks and the lower branches. In areas inundated at high tide, additional samples were collected on the cortex of palms, its rootlets, other angiosperm trees and from decomposing logs. Twenty-six species of liverworts and seven of mosses were identified. The most diverse and predominant liverwort family was the Lejeuneaceae with twenty-two species and two varieties and, among the mosses, the Calymperaceae with three species. Species affinities with other tropical mangroves were analyzed and liverworts were found to be the dominant element. Among the liverworts collected, two are new reports for Panama: Ceratolejeunea confusa and Frullanoides mexicana. Additional surveys of the cryptogamic vegetatio...

Canopy access was used to analyse the distribution and vertical stratification of bryophyte epiphytes within tree crowns at nine forest sites across a 3400 m elevational gradient in Peru, from the Amazonian basin to the high Andes. The stable isotope compositions of bryophyte organic material (<sup>13</sup>C/<sup>12</sup>C and <sup>18</sup>O/<sup>16</sup>O) are associated with surface water diffusive limitations and, along with C/N content, provide a generic index for the extent of cloud immersion. From lowland to cloud forest δ<sup>13</sup>C increased from −33‰ to −27‰, while δ<sup>18</sup>O increased from 16.3‰ to 18.0‰.

Life on a leaf: The development of spatial structure in epiphyll communities
Journal of Ecology, 2021
The spatial structure of biotic communities can be shaped by niche‐based or stochastic processes,... more The spatial structure of biotic communities can be shaped by niche‐based or stochastic processes, and the importance of both can change through time. Niche‐based processes include neighbour interactions, which can change in intensity and quality as communities develop in dependence of environmental conditions. Epiphylls, miniature communities of liverworts, lichens, algae and fungi on leaves, develop only in relatively moist forests, but their leaf‐surface habitat is still characterized by moisture stress, especially in more exposed parts of the forest. As neighbours may alleviate moisture stress, we expected that in forest gaps (dryer, brighter), epiphyll communities would show more positive neighbour interactions, resulting in more clustered spatial patterns, than in closed forest, in accordance with the stress‐gradient hypothesis. To understand how the processes shaping epiphyll communities change through time and differ between gaps and closed forest, we examined the fine‐scale spatial structure within and between epiphyll functional groups (algae, fungi, lichens and liverworts) during 12 months on 60 leaves across 12 sites in a tropical rainforest in Panama. We analysed changes in spatial positions and spatial associations within and between functional groups using spatial point pattern analysis based on repeated photography. Epiphyll densities increased through time for most epiphyll functional groups. However, although epiphyll groups changed their positions through time, the general types of spatial patterns remained similar for most groups: only lichen patterns shifted from mostly random to mostly aggregated through time. We found only random and aggregated spatial patterns within groups, while among groups we additionally found segregated spatial associations, but no consistent temporal trend. Patterns did not differ between gaps and closed forest, thus not supporting the stress‐gradient hypothesis. Synthesis. Our results only weakly support the assumption that community‐shaping processes change from neutral to niche‐based as communities develop. We do provide empirical evidence that epiphyll communities are dynamic and exhibit different spatial association patterns within than among groups. Empirical evidence suggests different interactions and processes within than between groups. Experimental studies and monitoring of individual epiphyll patches are recommended to shed further light on what processes shape life on leaves.

Canopy access was used to analyse the distribution and vertical stratification of bryophyte epiphytes within tree crowns at nine forest sites across a 3400 m elevational gradient in Peru, from the Amazonian basin to the high Andes. The stable isotope compositions of bryophyte organic material (13C/12C and18O/16O) are associated with surface water diffusive limitations and, along with C/N content, provide a generic index for the extent of cloud immersion. From lowland to cloud forest δ13C increased from −33‰ to −27‰, while δ18O increased from 16.3‰ to 18.0‰. Epiphytic bryophyte and associated canopy soil biomass in the cloud immersion zone was estimated at up to 45 t dry mass ha−1, and overall water holding capacity was equivalent to a 20 mm precipitation event. The study emphasizes the importance of diverse bryophyte communities in sequestering carbon in threatened habitats, with...

The species is distinguished by its large size, strongly costate thallus with crispate imperforate wings, dioicous condition and green, unicellular spores that are minutely papillose with tubercules dispersed on the borders and the distal face, and sometimes clustered in the center of the distal face. Nothoceros superbus has a combination o?Megaceros like spores and a Dendroceros-like thallus growth-form. The combination of these features supports its placement in the genus Nothoceros in the Dendrocerotaceae. Nomenclatural clarifications on Nothoceros endiviaefolius (Mont.) J. Haseg. and Nothoceros giganteas (Lehm. & Lindenb.) J. Haseg. are made. Based on new molecular and morphological data a new combination, Nothoceros canaliculatus (Pagan) comb, nov., is proposed.
