title: Data from: Rapid nitrogen fixation by canopy microbiome in tropical forest determined by both phosphorus and molybdenum

description: Biological nitrogen fixation is critical for the nitrogen cycle of
 tropical forests, yet we know little about the factors that control the
 microbial nitrogen-fixers that colonize the microbiome of leaves and
 branches that make up a forest canopy. Forest canopies are especially
 prone to nutrient limitation because they are (1) disconnected from soil
 nutrient pools, and (2) often subject to leaching. Earlier studies have
 suggested a role of phosphorus and molybdenum in controlling biological
 N-fixation rates, but experimental confirmation has hitherto been
 unavailable. We here present the results of a manipulation of canopy
 nutrient availability . Our findings demonstrate a primary role of
 phosphorus in constraining overall N-fixation by canopy cyanobacteria, but
 also a secondary role of molybdenum in determining per-cell fixation
 rates. A conservative evaluation suggests that canopy fixation can
 contribute to significant N fluxes at the ecosystem level, especially as
 bursts following atmospheric inputs of nutrient-rich dust.

title: Data from: Paleo-trajectories of forest savannization in the southern Congo

description: Tropical savanna and forest are thought to represent alternative stable
 states in ecosystem structure in some climates. The implication is that
 biomes are maintained by positive feedbacks, e.g., with fire, and that
 historical distributions could play a role in determining modern ones. In
 this context, climate alone does not govern transitions between biomes,
 and understanding the causes and pathways of such transitions becomes
 crucial. Here, we use a multi-proxy analysis of a 2000-year core to
 evaluate modes of transition in vegetation structure and fire regimes. We
 demonstrate a first transition c.1540 BP, when a cyclic fire regime
 entered a forested landscape, eventually resulting, by c.1060 BP, in a
 transition to a more open savanna-like or mosaicked structure. This
 pattern may parallel currently accelerating fire regimes in tropical
 forests suggesting that fires can savannize forests, but perhaps more
 slowly than feared. Finally, c.540 BP, a drought combined with
 anthropogenic influences resulted in a conclusive transition to savanna,
 probably resembling the modern landscape in the region. We show here that
 fire interacted with drought to transition forest to savanna, suggesting
 that disturbance by fire can be a major driver of biome change.

title: Data from: Acoustic and camera surveys inform models of current and future vertebrate distributions in a changing desert ecosystem

description: Aim: Maintaining biodiversity in the face of land use and climate change
 is a paramount challenge, particularly when distributions of many species
 remain incompletely known. Emerging technologies help address this data
 deficiency by facilitating the collection of spatially explicit data for
 multiple species from multiple taxa. In this study, we combine acoustic
 and visual sensor surveys to inform conservation and land-use planning in
 an area experiencing rapid climate and land-use change. Location: Mojave
 Desert, California, United States. Methods: We deployed camera traps and
 acoustic detectors at 210 sites between March and July 2016. We identified
 photographic detections of mammals and acoustic recordings of songbirds to
 the species-level and used multispecies occupancy models to estimate and
 evaluate species’ occupancy probabilities. We then extrapolated model
 results to the region, and forecasted how projected climate and land-use
 changes might affect species’ occupancy probabilities in 50 years. Lastly,
 we identified areas with high conservation value (i.e., high relative
 species richness) now and in 50 years, and related the distributions of
 these areas to land use designations. Results: We detected 15 mammal and
 68 songbird species. At the community-level, occupancy decreased with
 increasing temperatures and distances to woodlands. We forecasted that
 occupancy probabilities and areas with high conservation value would
 decline in 50 years due to projected increases in maximum temperatures,
 and identified that up to 43, 24, and 27% of land designated for renewable
 energy development, recreation, and military activities, respectively,
 encompassed these high value areas. Main conclusions: Cooler areas close
 to woodlands and water are of high conservation value to mammals and
 songbirds in the Mojave. These areas will become increasingly limited with
 changing climate, however, making their protection from human disturbance
 imperative. We encourage continued use of visual and acoustic sensors
 across large spatial, temporal, and taxonomic scales as tools to inform
 land use and wildlife conservation.

title: Data from: Hermaphroditism promotes mate diversity in flowering plants

description: PREMISE OF THE STUDY: Genetically diverse sibships are thought to increase
 parental fitness through a reduction in the intensity of sib competition,
 and through increased opportunities for seedling establishment in
 spatially or temporally heterogeneous environments. Nearly all research on
 mate diversity in flowering plants has focused on the number of fathers
 siring seeds within a fruit or on a maternal plant. Yet as hermaphrodites,
 plants can also accrue mate diversity by siring offspring on several
 pollen recipients in a population. Here we explore whether mate
 composition overlaps between the dual sex functions, and discuss the
 implications for plant reproductive success. METHODS: We established an
 experimental population of 49 Mimulus ringens (monkeyflower) plants, each
 trimmed to a single flower. Following pollination by wild bees, we
 quantified mate composition for each flower through both paternal and
 maternal function. Parentage was successfully assigned to 240 progeny, 98%
 of the sampled seeds. KEY RESULTS: Comparison of mate composition between
 male and female function revealed high mate diversity, with almost no
 outcross mates shared between the two sexual functions of the same flower.
 CONCLUSIONS: Dual sex roles contribute to a near doubling of mate
 diversity in our experimental population of Mimulus ringens. This finding
 may help explain the maintenance of hermaphroditism under conditions that
 would otherwise favor the evolution of separate sexes.

title: Data from: Shared neural underpinnings of multisensory integration and trial-by-trial perceptual recalibration in humans

description: Perception adapts to mismatching multisensory information, both when
 different cues appear simultaneously and when they appear sequentially.
 While both multisensory integration and adaptive trial-by-trial
 recalibration are central for behavior, it remains unknown whether they
 are mechanistically linked and arise from a common neural substrate. To
 relate the neural underpinnings of sensory integration and recalibration,
 we measured whole-brain magnetoencephalography while human participants
 performed an audio-visual ventriloquist task. Using single-trial
 multivariate analysis, we localized the perceptually-relevant encoding of
 multisensory information within and between trials. While we found neural
 signatures of multisensory integration within temporal and parietal
 regions, only medial superior parietal activity encoded past and current
 sensory information and mediated the perceptual recalibration within and
 between trials. These results highlight a common neural substrate of
 sensory integration and perceptual recalibration, and reveal a role of
 medial parietal regions in linking present and previous multisensory
 evidence to guide adaptive behavior.

title: Data from: Prognostic significance of serum albumin in patients with stable coronary artery disease treated by percutaneous coronary intervention

description: Background: Stable coronary artery disease (CAD) is known to have an
 increased risk of cardiovascular events. Serum albumin (Alb) is reported
 as a useful risk-stratification tool in cardiovascular diseases such as
 acute coronary syndrome or heart failure. However, the association between
 Alb and stable CAD is unclear. Thus, we aimed to investigate the
 prognostic significance of Alb in patients with stable CAD. Methods and
 results: We analyzed the data of all patients admitted to Shinonoi General
 Hospital between October 2014 and October 2017 for newly diagnosed stable
 CAD, treated via elective percutaneous coronary intervention, with the
 exception of old myocardial infarction. We collected data, including Alb,
 at admission. The primary endpoint was major adverse cardiac events (MACE;
 defined as all-cause death, non-fatal myocardial infarction, non-fatal
 stroke). In 204 enrolled patients (median age, 73 years), during a median
 follow-up of 783 days, 28 experienced MACE. Alb was significantly lower in
 patients with MACE than in those without (p&lt;0.001). In Kaplan-Meier
 analysis, low Alb predicted worse prognosis in MACE (p&lt;0.001). In
 multivariate Cox regression analysis, low Alb levels independently
 predicted MACE (p&lt;0.001) after adjusting for age and sex (HR 4.128
 [95% CI 1.632–10.440], p = 0.003), or, age and C-reactive protein (HR
 3.373 [95% CI 1.289–8.828], p = 0.013). Conclusions: Low Alb levels
 predicted MACE in patients with stable CAD.
description: Repository
 dataThis data is a
 retrospective, single-center cohort study data. The cohort included
 patients admitted to Shinonoi General Hospital between October 2014 and
 October 2017 for newly diagnosed stable CAD with the exception of old
 myocardial infarction, treated via elective PCI. Patients with malignancy
 were excluded. All patients were enrolled after the approval of the
 Shinonoi General Hospital Ethics Committee, and after written informed
 consent was obtained. The collected data included clinical
 characteristics, medical history, major risk factors for CAD,
 comorbidities, laboratory, electrocardiography, echocardiography, and
 angiographic data, discharge medications, and post-discharge follow-up
 findings. All data were fully anonymized before access. The investigation
 is consistent with the principles outlined in the Declaration of
 Helsinki.

title: Data from: Enhancement of thermoelectric properties of La-doped SrTiO3 bulk by introducing nanoscale porosity

description: Electron doped-SrTiO3 is a well-known n-type thermoelectric material,
 although the figure of merit of SrTiO3 is still inferior compared to
 p-type metal oxide-based thermoelectric materials due to its high lattice
 thermal conductivity. In this study, we have used different amount of the
 non-ionic surfactant F127 during sample preparation to introduce nanoscale
 porosities into bulk samples of La-doped SrTiO3. Thermopower is observed
 to be improved by the charge careers due to introduction of porosity into
 the bulk sample which resulted in lowering thermal conductivity due to
 enhanced phonon scattering. It has been observed that the porosities
 introduced into the bulk sample significantly improve the Seebeck
 coefficient and reduce the thermal conductivity by the charge carrier and
 phonon scattering respectively. Therefore, there is an overall enhancement
 in the power factor (PF) followed by dimensionless figure of merit (zT)
 over a wide scale of temperature. The sample 20 at% La-doped SrTiO3 with
 600 mg of F127 surfactant (SLTO 600F127) shows the maximum power factor of
 1.14 mWm-1K-2 at 647 K which is 35% higher than the sample without
 porosity (SLTO 0F127), and the same sample (SLTO 600F127) shows the
 maximum value of zT is 0.32 at 968 K with an average enhancement of 62% in
 zT in comparison to the sample without porosity (SLTO 0F127).

title: Data from: Plant community responses to environmentally-friendly piste management in northeast Iran

description: It is well-known that pistes have adverse effects on alpine ecosystems.
 Previous studies urged that pistes should be installed and managed in the
 ways to minimize negative impacts on natural habitats. However, the
 impacts of this type of management on the plant communities are not widely
 studied. The aim of this study was to examine species composition and
 biodiversity changes in an environmentally-friendly managed piste in
 northeast Iran. This piste has been established in a previously degraded
 alpine landscape. For the vegetation survey, we sampled 44 within and 28
 off-piste plots. Except for the piste management, other environmental
 factors were similar between the piste and off-piste plots. Dominant
 species were determined, and variation in community composition of the two
 areas was visualized. Also, Native species, phylogenetic, and functional
 Hill diversity of the two areas were compared. The results showed that
 there was a moderate differentiation in the species composition of the
 piste and off-piste. Two palatable species (i.e., Bupleurum falcatum and
 Melica persica) were dominant in the piste and were not recorded in the
 off-piste. The species diversity calculations results showed that the
 species diversity of the piste was higher than that of the off-piste.
 Phylogenetic Hill diversity at the level of frequent and dominant plants
 showed a similar result. The piste had a higher functional diversity in
 terms of functional richness, and functional diversity of frequent and
 dominant plants. Our findings imply, after 10 years, species,
 phylogenetic, and functional diversity of the piste is significantly
 improved. Environmentally-friendly piste management (EFPM) induced species
 composition change that led to emerging species that were absent in the
 off-piste. We can conclude that EFPM led to restoration of a degraded
 landscape. Long-term impacts of EFPM are still unknown, therefore, caution
 should be undertaken regarding the installation of new
 environmentally-friendly pistes in other areas.

title: Data from: Tree performance in a biodiversity enrichment experiment in an oil palm landscape

description: 1. Large-scale conversion of tropical forests into oil palm monocultures
 has led to dramatic losses of biodiversity and ecosystem functions. While
 ecological restoration is urgently needed in many oil palm landscapes,
 there is a lack of scientific knowledge of sustainable management
 strategies. 2. We established experimental tree islands of varying sizes
 (25 m2 to 1600 m2) and diversity levels (1, 2, 3 and 6 species) in an oil
 palm plantation in Sumatra, Indonesia. Six native multi-purpose tree
 species including Jengkol (Archidendron pauciflorum), Durian (Durio
 zibethinus), Petai (Parkia speciosa), Meranti (Shorea leprosula), Sungkai
 (Peronema canescens), and Jelutung (Dyera polyphylla) were planted between
 living and felled oil palms. Here, we analyze the controlling factors of
 tree growth and survival during the first four years at the level of local
 neighborhood and tree island. 3. We found a significant effect of
 diversity levels on tree productivity, i.e. basal area was higher in
 mixed-species than in single-species tree islands. This overyielding was
 attributed to enhanced tree growth, while mortality had no effect. In the
 local neighborhood, tree species richness had a positive effect on tree
 growth during the first year only, indicating that selection and dominance
 of well-performing species at high level of diversity are most likely
 driving overyielding. 4. Trees grew better away from living oil palms,
 suggesting tree-palm competition. Proximity to felled oil palms increased
 growth especially during the first years, during which the planted trees
 might have benefited from the additional available space and resources.
 Despite positive edge effects from the conventional oil palm management in
 the surrounding, tree island size had an overall positive effect on tree
 growth. 5. Synthesis and applications. We planted multiple native trees in
 an oil palm plantation following a tree island pattern. The establishment
 success differed widely among species. The selection of particular species
 is a decisive factor to foster a positive relationship between diversity
 andtree growth. Planting larger tree islands (e.g. 1’600 square meters) is
 a better option to enhance tree growth, but tree-palm competition implies
 a trade-off between tree growth and palm oil production locally.

title: Data from: Facilitation of balsam fir by trembling aspen in the boreal forest: do ectomycorrhizal communities matter?

description: Succession is generally well described above-ground in the boreal forest,
 and several studies have demonstrated the role of interspecific
 facilitation in tree species establishment. However the role of
 mycorrhizal communities for tree establishment and interspecific
 facilitation, has been little explored. At the ecotone between the mixed
 boreal forest, dominated by balsam fir and hardwood species, and the
 boreal forest, dominated by black spruce, several stands of trembling
 aspen can be found, surrounded by black spruce forest. Regeneration of
 balsam fir seems to have increased in the recent decades within the boreal
 forest, and it seems better adapted to grow in trembling aspen stands than
 in black spruce stands, even when located in similar abiotic conditions.
 As black spruce stands are also covered by ericaceous shrubs, we
 investigated if differences in soil fungal communities and ericaceous
 shrubs abundance could explain the differences observed in balsam fir
 growth and nutrition. We conducted a study centered on individual saplings
 to link growth and foliar nutrient concentrations to local vegetation
 cover, mycorrhization rate and mycorrhizal communities associated with
 balsam fir roots. We found that foliar nutrient concentrations and
 ramification indices (colonization by mycorrhiza per length of root) were
 greater in trembling aspen stands and were positively correlated to apical
 and lateral growth of balsam fir saplings. In black spruce stands, the
 presence of ericaceous shrubs near balsam fir saplings affected
 ectomycorrhizal communities associated with tree roots which in turn
 negatively correlated with N foliar concentrations. Our results reveal
 that fungal communities observed under aspen are drivers of balsam fir
 early growth and nutrition in boreal forest stands and may facilitate
 ecotone migration in a context of climate change.
