The biodiversity-productivity relationship (BPR) is foundational to our understanding of the global extinction crisis and its impacts on ecosystem functioning. Understanding BPR critical for accurate valuation effective conservation biodiversity. Using ground-sourced data from 777,126 permanent plots, spanning 44 countries most terrestrial biomes, we reveal a globally consistent positive concave-down BPR, showing that continued biodiversity loss would result in an accelerating decline forest...
ABSTRACT Soil organic carbon (SOC) is a valuable resource for mediating global climate change and securing food production. Despite an alarming rate of plant diversity loss, uncertainties concerning the effects on SOC remain, because not only stimulates litter inputs via increased productivity, thus enhancing SOC, but also microbial respiration, reducing SOC. By analysing 1001 paired observations mixtures corresponding monocultures from 121 publications, we show that both content stock are...
Abstract Controlled experiments have shown that global changes decouple the biogeochemical cycles of carbon (C), nitrogen (N), and phosphorus (P), resulting in shifting stoichiometry lies at core ecosystem functioning. However, response soil to natural ecosystems with different depths, vegetation types, climate gradients remains poorly understood. Based on 2,736 observations along profiles 0–150 cm depth from 1955 2016, we evaluated temporal C‐N‐P across subtropical China, where soils are...
Abstract The impacts of climate change on forest net biomass are poorly understood but critical for predicting forest's contribution to the global carbon cycle. Recent studies show change‐associated declines in mature plots. representativeness these plots regional forests, however, remains uncertain because we lack an assessment whether differ with age. Using data from varying ages 17 210 years, monitored 1958 2011 western Canada, found that has little effect forests ≤ 40 years age due...
Examining the relationship between tree diversity and ecosystem functioning has been a recent focus of forest ecology. Particular emphasis given to impact on productivity its potential mitigate negative global change effects; however, little attention paid mortality. This is critical because both mortality underpin dynamics therefore carbon sequestration. Neglecting leaves large part picture undocumented. Here we show that increasingly diverse stands have high probabilities. We found most...
Species compositional shifts have important consequences to biodiversity and ecosystem function services humanity. In boreal forests, from late-successional conifers early-successional deciduous broadleaves been postulated based on increased fire frequency associated with climate change truncating stand age-dependent succession. However, little is known about how has affected forest composition in the background between successive catastrophic fires forests. Using 1797 permanent sample plots...
Abstract Linking individual and stand-level dynamics during forest development reveals a scaling relationship between mean tree size density in stands, which integrates structure function. However, the nature of this so-called law its variation across broad spatial scales remain unquantified, linkage with demographic processes carbon remains elusive. In study, we develop theoretical framework compile broad-scale dataset long-term sample stands (n = 1,433) from largely undisturbed forests to...
Abstract Aim To determine the relationships between functional trait composition of forest communities and environmental gradients across scales biomes role species relative abundances in these relationships. Location Global. Time period Recent. Major taxa studied Trees. Methods We integrated abundance records from worldwide inventories associated traits (wood density, specific leaf area seed mass) to obtain a data set 99,953 149,285 plots (depending on trait) spanning all forested...
Species interactions affect ecosystem productivity. Positive (resource partitioning and facilitation) increase productivity while negative (species interference) decrease relative to the null expectations defined by monoculture yields. Effects of competitive competition) can be either positive or negative. Distinguishing effects species is therefore difficult, if not impossible, with current biodiversity experiments involving mixtures full density monocultures.To partition changes in...
Global change has been linked to significant increases in tree mortality the world's forests. Reduced longevity through increased growth rates suggested as one of mechanisms responsible for temporal mortality, but this idea not directly tested. Here we explicitly defined two testable hypotheses: (i) probability ageing driven with global and (ii) associated is higher faster growing trees. To test these hypotheses, examined changes 539 permanent sample plots monitored from 1960–2009, ages...
In the past two decades, forest management has undergone major paradigm shifts that are challenging current modelling architecture. New silvicultural systems, guidelines for natural disturbance emulation, a desire to enhance structural complexity, advances in successional theory, and climate change have all highlighted limitations of empirical models covering this range conditions. Mechanistic models, which focus on underlying ecological processes rather than specific conditions, potential...
