Leaf size varies by over a 100,000-fold among species worldwide. Although 19th-century plant geographers noted that the wet tropics harbor plants with exceptionally large leaves, latitudinal gradient of leaf has not been well quantified nor key climatic drivers convincingly identified. Here, we characterize worldwide patterns in size. Large-leaved predominate wet, hot, sunny environments; small-leaved typify environments only arid conditions; small leaves are also found high latitudes and...
Abstract Terrestrial ecosystems play a significant role in the global carbon cycle and offset large fraction of anthropogenic CO 2 emissions. The terrestrial sink is increasing, yet mechanisms responsible for its enhancement, implications growth rate atmospheric , remain unclear. Here using budget estimates, ground, satellite observations, multiple vegetation models, we report recent pause decline emissions that atmosphere, despite increasing We attribute observed to increases during past...
Abstract. Terrestrial photosynthesis is the basis for vegetation growth and drives land carbon cycle. Accurately simulating gross primary production (GPP, ecosystem-level apparent photosynthesis) key satellite monitoring Earth system model predictions under climate change. While robust models exist describing leaf-level photosynthesis, diverge due to uncertain photosynthetic traits parameters which vary on multiple spatial temporal scales. Here, we describe evaluate a GPP (photosynthesis per...
Abstract Plants invest a considerable amount of leaf nitrogen in the photosynthetic enzyme ribulose-1,5-bisphosphate carboxylase-oxygenase (RuBisCO), forming strong coupling and capacity. Variability nitrogen-photosynthesis relationship indicates different use strategies plants (i.e., fraction allocated to RuBisCO; fLNR), however, reason for this remains unclear as widely are adopted photosynthesis models. Here, we comprehensive database situ observations, remote sensing product chlorophyll...
Abstract Theory predicts that rising CO 2 increases global photosynthesis, a process known as fertilization, and this is responsible for much of the current terrestrial carbon sink. The estimated magnitude historic however, differs by an order between long-term proxies, remote sensing-based estimates biosphere models. Here we constrain likely effect on photosynthesis combining models, ecological optimality theory, sensing approaches emergent constraint based budget estimates. Our analysis...
The life span of leaves increases with their mass per unit area (LMA). It is unclear why. Here, we show that this empirical generalization (the foundation the worldwide leaf economics spectrum) a consequence natural selection, maximizing average net carbon gain over cycle. Analyzing two large trait datasets, evergreen and deciduous species diverse construction costs (assumed proportional to LMA) are selected by light, temperature, growing-season length in different, but predictable, ways. We...
Abstract Vegetation cover regulates the exchanges of energy, water and carbon between land atmosphere. Remotely-sensed fractional absorbed photosynthetically active radiation (fAPAR), a land-surface greenness measure, depends on allocation to foliage while also controlling photon flux for photosynthesis. Here we use an equation with just two globally fitted parameters describe annual maximum fAPAR as smaller water-limited value transpiring constant fraction precipitation, energy-limited...
Abstract. We present a benchmark system for global vegetation models. This provides quantitative evaluation of multiple simulated properties, including primary production; seasonal net ecosystem cover; composition and height; fire regime; runoff. The benchmarks are derived from remotely sensed gridded datasets site-based observations. allow comparisons annual average conditions inter-annual variability, they the impact spatial temporal biases in means variability to be assessed separately....

Plant functional traits provide information about adaptations to climate and environmental conditions, can be used explore the existence of alternative plant strategies within ecosystems. Trait data are also increasingly being parameter estimates for vegetation models. Here we present a new database from China. Most global types found in China, thus is relevant modeling. The China Database contains on morphometric, physical, chemical, photosynthetic 122 sites spanning range boreal tropical,...
