title: Canopy cover data from: Applied nucleation facilitates tropical forest recovery

description:   Applied nucleation, mostly based upon planting tree islands,
 has been proposed as a cost‐effective strategy to meet ambitious global
 forest and landscape restoration targets. We review results from a 15‐year
 study, replicated at 15 sites in southern Costa Rica, that compares
 applied nucleation to natural regeneration and mixed‐species tree
 plantations as strategies to restore tropical forest. We have collected
 data on planted tree survival and growth, woody vegetation recruitment and
 structure, seed rain, litterfall, epiphytes, birds, bats and leaf litter
 arthropods. Our results indicate that applied nucleation and plantation
 restoration strategies are similarly effective in enhancing the recovery
 of most floral and faunal groups, vegetation structure and ecosystem
 functions, as compared to natural regeneration. Seed dispersal and woody
 recruitment are higher in applied nucleation and plantation than natural
 regeneration treatments; canopy cover has increased substantially in both
 natural regeneration and applied nucleation treatments; and mortality of
 planted N‐fixing tree species has increased in recent years. These trends
 have led to rapid changes in vegetation composition and structure and
 nutrient cycling. The applied nucleation strategy is cheaper than
 mixed‐species tree plantations, but there may be social obstacles to
 implementing this technique in agricultural landscapes, such as
 perceptions that the land is not being used productively. Applied
 nucleation is likely to be most effective in cases where: planted
 vegetation nuclei enhance seed dispersal and seedling establishment of
 other species; the spread of nuclei is not strongly inhibited by abiotic
 or biotic factors; and the approach is compatible with restoration goals
 and landowner preferences. Synthesis and applications. Results from our
 15‐year, multi‐site study show that applied nucleation can be a
 cost‐effective strategy for facilitating tropical forest regeneration that
 holds promise for helping to meet large‐scale international forest
 restoration commitments.
description: We recorded vegetation point-intercepts at 2-5 m and &gt;5 m
 heights along eight parallel 48-m transects through our restoration plots
 at 12 sites. Transects were separated by 6 m and points along transects
 were separated by 4 m for a total of 96 points.  Where
 collected: 13 restoration sites in Coto Brus County, Puntarenas, Costa
 Rica

title: Data from: Local tropical forest restoration strategies affect tree recruitment more strongly than does landscape forest cover

description: Developing restoration strategies that accelerate natural successional
 processes and are resource‐efficient is critical to facilitating tropical
 forest recovery across millions of hectares of deforested lands in the
 tropics. We compared tree recruitment after a decade in three restoration
 treatments (natural regeneration, applied nucleation/island tree planting
 and plantation) and nearby reference forest in the premontane rain forest
 zone in southern Costa Rica. The study was replicated at 13 sites with a
 range of surrounding forest cover, enabling us to evaluate the relative
 influence of local restoration treatments and landscape forest cover on
 tree recruitment. Density of small‐seeded (&lt;5 mm),
 animal‐dispersed recruits was lower in natural regeneration than in
 applied nucleation, plantation or reference forest plots. Species
 richness, species density and density of medium (5–10 mm)‐ and
 large (&gt;10 mm)‐seeded, animal‐dispersed recruits were
 greatest in reference forest, intermediate in applied nucleation and
 plantation and lowest in natural regeneration plots. Recruit composition
 differed substantially between reference forest and all restoration
 treatments. In general, plantation recruit composition was more similar to
 reference forests and natural regeneration least similar; however, there
 was high within‐treatment variation. Models suggested weak support for the
 effect of surrounding forest cover on tropical tree recruit density and
 composition, as compared to restoration treatment and site conditions
 (e.g. elevation), in this intermediate forest cover landscape. Synthesis
 and applications. Applied nucleation appears to be a cost‐effective
 strategy as compared to plantation‐style planting to accelerate tropical
 forest recovery regardless of the amount of forest cover immediately
 adjacent to the site. However, even with active restoration interventions,
 forest recovery is a multidecade process that proceeds at highly variable
 rates.  
description: In June-July 2015 (9-11 years after plot establishment), we
 sampled tree seedlings (&gt;0.2 and &lt;1 m tall) and saplings
 (&gt;1 m tall and &lt;5 cm d.b.h.) in all restoration and in
 reference forests at six sites remnant forest nearby that had not been
 logged or used for agriculture. We identified saplings in 40, 2 × 4 m
 quadrats in each plot (320 m2 per plot) and recorded seedlings in 1 × 2 m
 quadrats nested within the sapling quadrats (80 m2 total). Quadrats were
 distributed in four belt transects of 10 each in natural regeneration,
 plantation, and reference forest treatments with one randomly located in
 each of the four quadrants of the plot. In the applied nucleation
 treatment, quadrats where distributed along six belt transects aligned
 from the interior to outside the initial planted areas of the three nuclei
 sizes, with six adjacent quadrats in small and medium nuclei and seven in
 large nuclei. The 5-m edge at the perimeter of the plot was not
 sampled.

title: Data from: Ant–scale mutualism increases scale infestation, decreases folivory, and disrupts biological control in restored tropical forests

description: Ant–hemipteran mutualisms can have positive and negative effects on host
 plants depending on the level of hemipteran infestation and plant
 protection conferred by ants against folivory. Differential effects of
 such mutualisms on plant survival are well documented in undisturbed and
 ant‐invaded systems, but few have explored how anthropogenic disturbance
 affects interactions between hemipterans and native ant species and what
 the consequences may be for recovering ecosystems. Within a fragmented
 landscape in Costa Rica, restored tropical forests harbor a mutualism
 between the native ant Wasmannia auropunctata and the
 scale insect Alecanochiton marquesi on the abundant,
 early‐successional tree Conostegia xalapensis. I
 added A. marquesiscales
 to C. xalapensis seedlings and either allowed
 or excluded W. auropunctata to investigate if
 this mutualism leads to increased scale infestation, decreased scale
 mortality, and decreased folivory. I also examined whether these
 effects are mediated by the percentage of remnant forest cover in the
 landscape. I found that seedlings with ants excluded had fewer scale
 insects and higher herbivory than plants with ants present. I also found
 evidence that scale mortality due to fungal attack and parasitism was
 higher on ant‐excluded versus ant‐allowed seedlings but only at sites with
 high surrounding landscape forest cover. Together, these results suggest
 that mutualisms between scale insects and native ants can promote scale
 infestation, reduce folivory on native plant species, and potentially
 disrupt biological control of scale insects in recovering tropical
 forests. Further, my experiment underscores the importance of remnant
 tropical forests as sources of biological control in anthropogenically
 disturbed landscapes.
description: Data collected includes abundance data for A. marquesi in both
 March 2018 when the experiment began and June 2018 at the end of the
 experiment. Data also included mortality of A. marquesi due to fungi and
 parasitism, W. auropunctata abundance, and change in percent folivory on
 leaves of C. xalapensis after the end of the experiment in June 2018.
 Percent landscape forest cover at buffers out to 650 m are also included
 in the dataset.

title: Data from: Rules of thumb for predicting tropical forest recovery

description: Natural regeneration is increasingly recognized as a potentially
 cost‐effective strategy to reach ambitious forest landscape restoration
 targets, but rates of recovery are notoriously variable. We asked how well
 initial habitat conditions after cessation of agriculture predict forest
 recovery after nearly a decade. We aimed to provide land managers with
 general rules of thumb to assess when it is necessary to invest resources
 in active restoration, such as tree planting, to accelerate forest
 recovery. Location: Coto Brus County, Puntarenas, Costa Rica.
  
description: We compiled
 data on initial vegetation structure, soil nutrients, prior land‐use
 history and surrounding forest cover at 13 sites. After 8.5 years, we
 measured vegetation indicators commonly used to assess forest recovery,
 namely amount of canopy closure and number and diversity of woody
 recruits. Two variables, grass cover
 and canopy closure, measured 1.5 years after site abandonment, explained
 47–87% of five of the six response variables after 8.5 years; recovery was
 faster in sites with lower grass cover and higher canopy closure
 initially. Waiting an additional year to measure initial vegetation
 variables did not improve model fit. Time since the original forest was
 cleared explained 62% of change in canopy cover, whereas percentage of
 surrounding forest cover, length of pasture use and soil variables
 explained minimal additional variation.

title: Data from: Litterfall and nutrient dynamics shift in tropical forest restoration sites after a decade of recovery

description: Multi‐year studies comparing changes in litterfall biomass and nutrient
 inputs in sites under different restoration practices are lacking. We
 evaluated litterfall dynamics and nutrient inputs at 5 yr and
 after a decade of recovery in four treatments (natural regeneration—no
 planting, plantation—entire area planted, tree islands—planting in
 patches, and reference forest) at multiple sites in an agricultural
 landscape in southern Costa Rica. We inter‐planted two native species
 (Terminalia amazonia and Vochysia guatemalensis) and two
 naturalized N‐fixing species (Inga edulis and Erythrina
 poeppigiana) in plantation and island treatments. Although litterfall N
 was higher in plantations in the first sampling period, litter production
 and overall inputs of C, N, Ca, Mg, P, Cu, Mn, and Fe did not differ
 between island, plantation, or reference forest after a decade; however,
 all were greater than in natural regeneration. Potassium inputs were lower
 in the natural regeneration, intermediate in island and plantation, and
 greater in reference forest. The percentage of litterfall comprised by the
 N‐fixing planted species declined by nearly two‐thirds in both plantations
 and islands between sampling periods, while the percentage
 of V. guatemalensis more than doubled, and the
 percentage from naturally regenerated species increased from 27 to 47
 percent in islands. Island and plantation treatments were equally
 effective at restoring litterfall and nutrient inputs to levels similar to
 the reference system. The nutrient input changed substantially over the
 7‐yr interval between measurements, reflecting shifts in vegetation
 composition and demonstrating how rapidly nutrient cycling dynamics can
 change in recovering forests.
description: We examined changes in litter and nutrient dynamics in tropical
 forest restoration sites after a decade of recovery in southern Costa
 Rica. Each site contained three 0.25-ha treatment plots: natural
 regeneration, trees planted in patches or “islands”, and tree plantations.
 Sites spanned elevational (1100-1430 m) and deforestation gradients (4-94%
 forest cover within a 100-m radius around each site). Within sites,
 treatments were separated by =5 m; restoration sites were separated by
 1-10 km.

title: Data from: Reduced aboveground tree growth associated with higher arbuscular mycorrhizal fungal diversity in tropical forest restoration

description: Establishing diverse mycorrhizal fungal communities is considered
 important for forest recovery, yet mycorrhizae may have complex effects on
 tree growth depending on the composition of fungal species present. In an
 effort to understand the role of mycorrhizal fungi community in forest
 restoration in southern Costa Rica, we sampled the arbuscular mycorrhizal
 fungal (AMF) community across eight sites that were planted with the same
 species (Inga edulis, Erythrina poeppigiana, Terminalia
 amazonia, and Vochysia guatemalensis) but varied twofold
 to fourfold in overall tree growth rates. The AMF community was measured
 in multiple ways: as percent colonization of host tree roots, by DNA
 isolation of the fungal species associated with the roots, and through
 spore density, volume, and identity in both the wet and dry seasons.
 Consistent with prior tropical restoration research, the majority of
 fungal species belonged to the genus Glomus and
 genus Acaulospora, accounting for more than half of the species
 and relative abundance found on trees roots and over 95% of spore density
 across all sites. Greater AMF diversity correlated with lower soil organic
 matter, carbon, and nitrogen concentrations and longer durations of prior
 pasture use across sites. Contrary to previous literature findings, AMF
 species diversity and spore densities were inversely related to tree
 growth, which may have arisen from trees facultatively increasing their
 associations with AMF in lower soil fertility sites. Changes to AMF
 community composition also may have led to variation in disturbance
 susceptibility, host tree nutrient acquisition, and tree growth. These
 results highlight the potential importance of fungal–tree–soil
 interactions in forest recovery and suggest that fungal community dynamics
 could have important implications for tree growth in disturbed soils.
description: Arbuscular mycorrhizal fungi (AMF) community data in relation to
 eight of the sites located near the town of Agua Buena (8° 44′ 36″ N, 82°
 58′ 04″ W) and Las Cruces Biological Station (8° 47′ 7″ N, 82° 57′ 32″ W)
 in Coto Brus county in southern Costa Rica.  The eight sites included BR,
 SC, SP, AC, HR, OM, BB, and EC (renamed sites 1-8, respectively, in the
 published article). AMF community data included: percent colonization of
 host tree roots; identification of the fungal species associated with
 trees roots through DNA isolation; and spore density, volume, and identity
 in both the wet and dry seasons. Data also included average soil
 characteristics per sites (taken from 2012 dataset) and tree growth (as
 height and diameter at breast height per year) per tree species and
 site.

title: MassIVE MSV000100573 - Complexity Reduction and Sustaining Plant Growth Promotion in a Beneficial Sorghum
title: The inherent complexity and functional redundancy of natural plant microbiomes present a formidable barrier to elucidating the manifold biological interactions. Synthetic microbial communities (SynComs) offer a tractable experimental system to decouple these complex interactions. Beyond their usefulness as tools for basic science, SynComs may be used as tools for crop improvement. This study outlines a top-down strategy to simplify a beneficial, SynCom, originally derived from Sorghum, while preserving significant plant growth promotion. We assessed colonization and plant growth promotion of four different community compositions representing diverse complexity reduction strategies. This process resulted in a significantly simplified community, SRC2v4, which retains substantial, though reduced, plant growth promotion efficacy compared to the original consortium. The resulting reduced consortium is highly stable, soil-independent, and provides a proof-of-concept for the rational design of microbial products. Characterization of longitudinal plant transcriptional responses to SRC2v4 revealed a spatiotemporal dynamic transduction of SynCom perception defined by flavonoid production and regulation of hormone modulation machinery. Our findings offer a framework for the development of next-generation microbial products for sustainable agriculture.
