The spatial scaling effect of canopy FAPAR retrieved by remote sensing
2014 IEEE Geoscience and Remote Sensing Symposium, 2014 Climate and land-atmosphere models rely on accurate land-surface parameters, such as the Fraction of Absorbed Photo synthetically Active Radiation (FAPAR). It is known that FAPAR values retrieved from remote sensing images suffer from scaling effects. Scaling transformation aims to derive accurate FAPAR values at a specific scale from values at other ...

Environmental influences on the maximum quantum yield of terrestrial primary production. [PDF]
New PhytolTemperature and aridity effects on terrestrial ecosystems' intrinsic quantum yield. Summary Historically, terrestrial biosphere models (TBMs) have assigned the intrinsic (maximum) quantum yield of photosynthesis (ϕ0) a constant value for each plant functional type. However, experimental studies have shown that ϕ0 – when measured on light‐adapted leaves

IAM-FIRE: A Climate Emulator-Based Framework to Project Wildfire Impacts and Risks for Integrated Assessment Models. [PDF]
Glob Chang BiolCurrent models can overestimate how much carbon forests can store if they ignore the growing threat of wildfires. To solve this, we develop a new tool called IAM‐FIRE to predict global wildfires and associated carbon emissions through the year 2100. The results show how future fire impacts depend on human choices. If we rapidly cut emissions and ensure

An eco-evolutionary optimality model explains the acclimated temperature response of photosynthesis. [PDF]
New PhytolSummary The optimal temperature of photosynthesis (Topt) generally increases with plant growth temperature. Changes in Topt are associated with changes in the maximum carboxylation capacity at 25°C (Vcmax25) and the maximum electron transport rate at 25°C (Jmax25). The ratio between Jmax25 and Vcmax25 declines with warming.

Global Assessment of Environmental and Plant-Trait Influences on Root: Shoot Biomass Ratios. [PDF]
Glob Chang BiolWe assembled a large global dataset by combining several previous compilations to test eco‐evolutionary optimality (EEO) hypotheses about how plants allocate carbon above‐ and below‐ground (root: shoot biomass ratios). Our analysis shows how carbon allocation in woody and herbaceous plants responds to environmental conditions and plant traits.
