Data from: Acceleration and novelty: community restoration speeds recovery and transforms species composition in Andean cloud forest
Community-based tropical forest restoration projects, often promoted as a win-win solution for local communities and the environment, have increased dramatically in number in the past decade. Many such projects are underway in Andean cloud forests, which, given their extremely high biodiversity and history of extensive clearing, are understudied. This study investigates the efficacy of community-based tree-planting projects to accelerate cloud forest recovery, as compared to unassisted natural regeneration. This study takes place in northwest Andean Ecuador, where the majority of the original, highly diverse cloud forests have been cleared, in five communities that initiated tree-planting projects to restore forests in 2003. In 2011, we identified tree species along transects in planted forests (n = 5), naturally regenerating forests (n = 5), and primary forests (n = 5). We also surveyed 120 households about their restoration methods, tree preferences, and forest uses. We found that tree diversity was higher in planted than in unplanted secondary forest, but both were less diverse than primary forests. Ordination analysis showed that all three forests had distinct species compositions, although planted forests shared more species with primary forests than did unplanted forests. Planted forests also contained more animal-dispersed species in both the planted canopy and in the unplanted, regenerating understory than unplanted forests, and contained the highest proportion of species with use value for local people. While restoring forest increased biodiversity and accelerated forest recovery, restored forests may also represent novel ecosystems that are distinct from the region's previous ecosystems and, given their usefulness to people, are likely to be more common in the future.
Data from: Interglacial genetic diversification of Moussonia deppeana (Gesneriaceae), a hummingbird-pollinated, cloud forest shrub in northern Mesoamerica
Recent empirical work on cloud forest-adapted species supports the role of both old divergences across major geographical areas and more recent divergences attributed to Pleistocene climate changes. The shrub Moussonia deppeana is distributed in northern Mesoamerica, with geographically disjunct populations. Based on sampling throughout the species range and employing plastid and nuclear markers, we (i) test whether the fragmented distribution is correlated with main evolutionary lineages, (ii) reconstruct its phylogeographical history to infer the history of cloud forest in northern Mesoamerica and (iii) evaluate a set of refugia/vicariance scenarios for the region and demographic patterns of the populations whose ranges expanded and tracked cloud forest conditions during the Last Glacial Maximum. We found a deep evolutionary split in M. deppeana about 6–3 Ma, which could be consistent with a Pliocene divergence. Comparison of variation in plastid and nuclear markers revealed several lineages mostly congruent with their isolated geographical distribution and restricted gene flow among groups. Results of species distribution modelling and coalescent simulations fit a model of multiple refugia diverging during interglacial cycles. The demographic history of M. deppeana is not consistent with an expanding–contracting cloud forest archipelago model during the Last Glacial Maximum. Instead, our data suggest that populations persisted across the geographical range throughout the glacial cycles, and experienced isolation and divergence during interglacial periods.
Data from: Consequences of divergence and introgression for speciation in Andean cloud forest birds
Divergence with gene flow is well documented and reveals the influence of ecological adaptation on speciation. Yet it remains intuitive that gene exchange inhibits speciation in many scenarios, particularly among ecologically similar populations. The influence of gene flow on the divergence of populations facing similar selection pressures has received less empirical attention than scenarios where differentiation is coupled with local environmental adaptation. I used a paired study design to test the influence of genomic divergence and introgression on plumage differentiation between ecologically similar allopatric replacements of Andean cloud forest birds. Through analyses of short-read genome-wide sequences from over 160 individuals in 16 co-distributed lineages, I found that plumage divergence is associated with deep genetic divergence, implicating a prominent role of geographic isolation in speciation. By contrast, lineages that lack plumage divergence across the same geographic barrier are more recently isolated or exhibit a signature of secondary genetic introgression, indicating a negative relationship between gene flow and divergence in phenotypic traits important to speciation. My results suggest that the evolutionary outcomes of cycles of isolation and divergence in this important theatre of biotic diversification are sensitive to time spent in the absence of gene flow.
Data from: Nurse-based restoration of degraded tropical forests with tussock grasses: experimental support from the Andean cloud forest
1. The degradation of the Andean cloud forest raises strong biological conservation issues and threatens the sustainability of a crucial water resource. The idea that nurse-based restoration can accelerate the recovery of these forests is underexplored, despite its promise as a restoration technique. Recent conceptual models predict that facilitation among plants may be an important mechanism, but there is a lack of strong empirical support. We gathered experimental data to test this prediction and explore the relevance of using nurse-based forest restoration in these environments. 2. A 20-month factorial experimental design in the Andean tropical cloud forest was established. We measured the survival and estimated the biomass production of transplanted seedlings of a keystone canopy forest species, Ceroxylon echinulatum (Arecaceae), in a deforested area in the presence/absence of herbivory, a potential nurse plant (the tussock grass Setaria sphacelata, Poaceae), and artificial shade. 3. The joint effects of deforestation and herbivory led to the death of all seedlings, whereas most seedlings survived in the adjacent forest, which was used as the control. The presence of nurse plants led to significantly higher survival and growth of Ceroxylon seedlings throughout the experiment, regardless of herbivore presence. 4. The nurse effects were explained by a reduction of the relative abiotic stress experienced by the seedlings outside the forest, i.e. the consistently decreasing maximum vapour pressure deficit. Furthermore, nurse tussocks delayed and reduced the effects of herbivory by offering physical protection and a refuge for seedlings against detection by herbivores. However, the effects of herbivory and abiotic stress on facilitation were not additive. 5. Synthesis and applications: Facilitation in degraded cloud forest can be intense as soon as the beneficiary plants are driven away from their physiological optimum (relative abiotic stress) and/or are confronted by herbivory. Using pre-established exotic tussock grasses as a nurse-based restoration technique in degraded cloud forest is a low-cost, non-detrimental (to biodiversity) option, especially in the absence of nurse trees and shrubs. The success of this method requires transplanting seedlings at the base of tussocks.
Data from: Historical reconstruction of climatic and elevation preferences and the evolution of cloud forest-adapted tree ferns in Mesoamerica
Background. Cloud forest, characterized by a persistent, frequent or seasonal low-level cloud cover and a fragmented distribution, is one of the most threatened habitats especially in the Neotropics. Tree ferns are among the most conspicuous elements in these forests and ferns are restricted to regions in which minimum temperatures rarely drop below freezing and rainfall is high and evenly distributed around the year. Current phylogeographic data suggest that some of the cloud forest-adapted species remained in situ or expanded to the lowlands during glacial cycles and contracted allopatrically during the interglacials. Although the observed genetic signals of population size changes of cloud forest-adapted species including tree ferns correspond to predicted changes by Pleistocene climate change dynamics, the observed patterns of intraspecific lineage divergence showed temporal incongruence. Methods. Here we combined phylogenetic analyses, ancestral area reconstruction, and divergence time estimates with climatic and altitudinal data (environmental space) for phenotypic traits of tree fern species to make inferences about evolutionary processes in deep time. We used phylogenetic Bayesian inference and geographic and altitudinal distribution of tree ferns to investigate the ancestral area and elevation and environmental preferences of Mesoamerican tree ferns. The phylogeny was then used to estimate divergence times and ask whether the ancestral area and elevation and environmental shifts were linked to climatic events and historical climatic preferences. Results. Bayesian trees retrieved Cyathea, Alsophila, Gymnosphaera and Sphaeropteris in monophyletic clades. Splits for species in these genera found in the Mesoamerican cloud forests are recent, from the Neogene to the Quaternary. Australia was identified as the ancestral area for the clades of these genera, except for Gymnosphaera that was Mesoamerica. Climate tolerance was not divergent from hypothesized ancestors for the four most significant variables or elevation. For elevational shifts we found repeated changes from low to high elevations. Conclusions. Our data suggest that representatives of Cyatheaceae main lineages migrated from Australia to Mesoamerican cloud forests in different times and have persisted in these environmentally unstable areas but extant species diverged recently from their ancestors.
Data from: Genetic signature of population fragmentation varies with mobility in seven bird species of a fragmented Kenyan cloud forest
Habitat fragmentation can restrict geneflow, reduce neighbourhood effective population size, and increase genetic drift and inbreeding in small, isolated habitat remnants. The extent to which habitat fragmentation leads to population fragmentation, however, differs among landscapes and taxa. Commonly, researchers use information on the current status of a species to predict population effects of habitat fragmentation. Such methods, however, do not convey information on species-specific responses to fragmentation. Here we compare levels of past population differentiation, estimated from microsatellite genotypes, with contemporary dispersal rates, estimated from multi-strata capture-recapture models, to infer changes in mobility over time in seven sympatric, forest-dependent bird species of a Kenyan cloud forest archipelago. Overall, populations of sedentary species were more strongly differentiated and clustered compared to those of vagile ones, while geographic patterning suggested an important role of landscape structure in shaping genetic variation. However, five of seven species with broadly similar levels of genetic differentiation nevertheless differed substantially in their current dispersal rates. We conclude that post-fragmentation levels of vagility, without reference to past population connectivity, may not be the best predictor of how forest fragmentation affects the life-history of forest-dependent species. As effective conservation strategies often hinge on accurate prediction of shifts in ecological and genetic relationships among populations, conservation practices based solely upon current population abundances or movements may, in the long term, prove to be inadequate.
Data from: Do artificial nectar feeders affect bat–plant interactions in an Ecuadorian cloud forest?
Plant–pollinator interactions are critical to ecosystems. However, when artificial nectar feeders are available in an area, they could draw pollinators away from plants. We tested the effects of artificial nectar feeders in an Ecuadorian cloud forest on four aspects of bat–plant interactions: (1) bat relative abundance; (2) bat pollen loads; (3) flower visitation rates, and (4) breeding success of a bat-pollinated species (Burmeistera glabrata). We divided the study site into areas close to (~30 m) and far from (~500 m) three different feeder sites. At each distance, we captured nectar bats (Anoura caudifer, Anoura cultrata, and Lonchophylla robusta) to estimate their relative abundance and to collect pollen from fur and fecal samples. We also videotaped flowers to estimate bat visitation rates and recorded different breeding success variables of B. glabrata. We found that areas close to feeders have higher relative bat abundance by a factor of 40. In spite of this, the presence of feeders did not affect bat pollen loads, nor the flower visitation rates and breeding success of B. glabrata. Interestingly, there were differences in pollen loads between the three bat species, in that L. robusta individuals rarely carried pollen and were only captured near feeders.

Humility Brings Prosperity gate - point cloud
A big point cloud of the Humility Brings Prosperity gate, now installed in Gallery 200 at Mia. *The gate comes from Shanxi province, which, because of its dry climate, contains the largest concentration of surviving historic wooden structures in China. An inscription on the main beam dates the gate to 1858, during the Qing dynasty (1644–1912).* [More info](https://collections.artsmia.org/art/127331/humility-brings-prosperity-gate-china) *This imposing gate once formed the entrance to the main courtyard of an urban middle-class family compound. The four-character panel over the doorway reads, Humility Brings Prosperity (Lüqian Jianfeng 履謙漸豐). The gate demonstrates the hallmarks of traditional Chinese architecture: a post-and-lintel structure that supports a graceful gable roof and intricate rafters, as well as brackets that extend the eaves and provide decoration. Like other works of traditional Chinese architecture, no glue or nails were used, and the gate was assembled using only joinery and wooden pins.* Source: Objaverse 1.0 / Sketchfab
Tregeseal Entrance Grave - point cloud
This barrow was excavated in 1879 by WC Borlase. The chamber survives with two capstones still in place. It is oriented NW-SE, but we do not know which end was the original entrance. Finds include sherds, ashes (cremations), a whetstone in the chamber and a Middle Bronze Age ribbon handled urn in the cist. The urn is now in the British Museum. It is possible that the monument present today represents two phases - an original neolithic chambered barrow with a later Bronze Age cist, which may have also been when the mound was enlarged. The chamber is 3.8m long, averaging 1.2m wide. The north end is covered by two stone slabs for a distance of 1.9m. The internal height of the chamber is 0.7m. The mound denotes the extent of the barrow, marked by possible kerb stones.
