1 Litter decomposition recycles nutrients and causes large fluxes of carbon dioxide into the atmosphere. It is typically assumed that climate, litter quality decomposer communities determine decay rates, yet few comparative studies have examined their relative contributions in tropical forests. 2 We used a short-term litterbag experiment to quantify effects quality, placement mesofaunal exclusion on 23 forests 14 countries. Annual precipitation varied among sites (760–5797 mm). At each site,...
Abstract The last half‐a‐century has seen a marked demand for authentic citizen participation in public policy‐and decision‐making, not least the field of sustainability. depth and forms engagement nature‐based solutions (NBS), example, how such shapes their trajectories is gaining increasing attention. In this paper, we analyze current implications 58 NBS case studies conducted 21 cities light supporting wider sustainability goals. Our results show that while tokenistic dominate across...
There is currently a lack of in-situ environmental data for the calibration and validation remotely sensed products development verification models. Crowdsourcing increasingly being seen as one potentially powerful way increasing supply but there are number concerns over subsequent use data, in particular quality. This paper examined crowdsourced from Geo-Wiki crowdsourcing tool land cover to determine whether were significant differences quality between answers provided by experts...
High biodiversity of forests is not predicted by traditional models, and evidence for trade‐offs those models require limited. High‐dimensional regulation (e.g., N factors to regulate species) has long been recognized as a possible alternative explanation, but it be seriously pursued, because only few limiting resources are evident trees, analysis multiple interactions challenging. We develop hierarchical model that allows us synthesize data from long‐term, experimental, sets with processes...
Abstract Global land cover is an essential climate variable and a key biophysical driver for earth system models. While remote sensing technology, particularly satellites, have played role in providing datasets, large discrepancies been noted among the available products. use typically more difficult to map many cases cannot be remotely sensed. In-situ or ground-based data high resolution imagery are thus important requirement producing accurate datasets this precisely what lacking. Here we...
As ecological data are usually analysed at a scale different from the one which process of interest operates, interpretations can be confusing and controversial. For example, hypothesised differences between species do not operate level, but concern individuals responding to environmental variation, including competition with neighbours. Aggregated many subject spatio-temporal variation used produce species-level averages, marginalise away relevant (process-level) scale. Paradoxically,...
Summary Carbon gain during phenological avoidance of canopy shade by an understorey plant depends on the extent avoidance, leaf stage and whether young old leaves can exploit greater light availability in spring autumn. For Asimina triloba (L.) Dunal., Aesculus glabra Willd., Acer saccharum Marsh., Lindera benzoin Blume Carpinus caroliniana Walt. a deciduous forest Illinois, USA, with at full size ranged from 0 days for to 24 , brought 36–98% estimated total annual irradiance. Autumn was...
Summary Increases in primary production may occur if plants respond to climate warming with prolonged growing seasons, but not local adaptation, cued by photoperiod, limits phenological advance. It has been hypothesized that trees diffuse‐porous xylem anatomy and early successional species most warming. Within species, northern populations due the fact seasons are relatively short. Species sensitive spring temperature show little overall response reduced chilling fall/winter offsets...
Anthropogenic climate change has altered temperate forest phenology, but how these trends will play out in the future is controversial. We measured effect of experimental warming 0.6-5.0 °C on phenology a diverse suite 11 plant species deciduous understory (Duke Forest, North Carolina, USA) relatively warm year (2011) and colder (2013). Our primary goal was to dissect temperature affects timing spring budburst, flowering, autumn leaf coloring for functional groups with different growth...
Forecasting how global warming will affect onset of the growing season is essential for predicting terrestrial productivity, but suffers from conflicting evidence. We show that accurate estimates require ways to connect discrete observations changing tree status (e.g., pre- vs. post budbreak) with continuous responses fluctuating temperatures. By coherently synthesizing temperature variation, we accurately quantify increasing variation accelerates growth. Application experiments at two...
Volunteered geographic information (VGI) is the assembly of spatial based on public input. While VGI has proliferated in recent years, assessing quality volunteer-contributed data proven challenging, leading some to question efficiency such programs. In this paper, we compare several metrics for individual volunteers' contributions. The were product 'Cropland Capture' game, which thousand volunteers assessed 165,000 images presence cropland over course 6 months. We compared agreement between...
From state-based developmentalism to community-based initiatives market-based conservation, the Brazilian Amazon has been a laboratory of development interventions for over 50 years. The region is now confronting devastating COVID-19 pandemic amid renewed environmental pressures and increasing social inequities. While these forces are shaping present future region, also become an incubator local innovations efforts pressures. Often overlooked, place-based involving individual...
Summary Spring ephemeral herb species in temperate deciduous forests are active above‐ground only briefly each year. This study tested experimentally how two countervailing constraints – cold and darkness influence the phenology of six spring species. Dormancy underground structures, maintained by temperatures a growth chamber, was broken at 25‐day intervals from January or February to June consecutive years. Upon emergence, survival flowering were measured on cohorts grown outdoors. Shade...
Abstract Drone‐based remote sensing is a promising new technology that combines the benefits of ground‐based and satellite‐derived forest monitoring by collecting fine‐scale data over relatively large areas in cost‐effective manner. Here, we explore potential GatorEye drone‐lidar system to monitor tropical succession canopy structural attributes including height, spatial heterogeneity, gap fraction, leaf area density (LAD) vertical distribution, Shannon index (an LAD), (LAI), understory LAI....
The Amazon has a diverse array of social and environmental initiatives that adopt forest-based land-use practices to promote rural development support local livelihoods. However, they are often insufficiently recognized as transformative pathways sustainability the factors explain their success remain understudied. To address this gap, paper proposes pursue three particular more likely generate improvements in social-ecological outcomes: (1) maintaining close connections with grassroots, (2)...
Abstract In this article, we use a new game‐based tool to evaluate the immediate and longer term behavioral change potential of three different payments for ecosystem services (PES) delivery mechanisms: direct individual performance, group insurance. Results from four rural shifting‐cultivation dependent communities in Lao PDR suggest that easily understood group‐oriented incentives yield greatest resource‐use reduction experience less free‐riding. Group‐based may succeed because they...
Many semi-arid coniferous forests in western North America have reached historically unprecedented densities over the past 150 years and are dominated by shade-tolerant trees. Silvicultural treatments generally open canopy but may not restore shade-intolerant species. We determined crossover-point irradiance (CPI) (light at which height growth rank of pairs species changes) for seedlings Sierra Nevada mixed-conifer forest used these to interpret light environments produced fuels-reduction...
Accuracy assessment, also referred to as validation, is a key process in the workflow of developing land cover map. To make this open and transparent, we have developed new online tool called LACO-Wiki, which encapsulates into set four simple steps including uploading map, creating sample from interpreting with very high resolution satellite imagery generating report accuracy measures. The aim paper present main features followed by an example how it can be used for assessment For purpose...
Global efforts for biodiversity protection and land use-based greenhouse gas mitigation call increases in the effectiveness efficiency of environmental conservation. Incentive-based policy instruments are key tools meeting these goals, yet their might be undermined by such factors as social norms regarding whether payments considered fair. We investigated causal link between equity conservation effort with a randomized real-effort experiment forest 443 users near tropical national park...
