Abstract Climate change will impact precipitation variability, potentially accelerating climate-terrestrial carbon feedbacks. However, the response of ecosystems to variability is difficult constrain due myriad physiological and abiotic variables that limit terrestrial productivity. Based on a combination satellite imagery global network daily data, we present here statistical framework isolate gross primary productivity five biomes collectively account for 50% land area. The mesic grasslands forests decreases by ~28% ~7% (respectively) in more irregular rain within year, while sensitivity halved higher year-to-year variability. Xeric are similarly impacted intra-annual rainfall variance, but they show an increase with interannual Conversely, boreal increases under both timescales. We conclude projected changes have measurable sink.

Summary Canopy temperature T can is a key driver of plant function that emerges as result interacting biotic and abiotic processes properties. However, understanding controls on forecasting canopy responses to weather extremes climate change are difficult due sparse measurements at appropriate spatial temporal scales.

Abstract Several plant species such as grasses are dominant in many habitats including arid and semi-arid areas. These survive these regions by developing exclusive structures, which helps the collection of atmospheric water. Before collected water evaporates, structures have unique canopy structure for transportation that plays an equivalent share fog-harvesting mechanism. In this review, gaseous harvesting mechanisms their affinity measurements were discussed.

Plant leaf temperatures can differ from ambient air temperatures. A temperature gradient in a gas mixture gives rise to phenomenon known as thermodiffusion, which operates addition ordinary diffusion. Whilst transpiration is generally understood be driven solely by the diffusion of water vapour along concentration gradient, we consider implications thermodiffusion for transpiration. We develop new modelling framework that introduces effects on rate, E. By applying this framework, quantify proportion E attributable set physiological and environmental conditions, varied over wide range. Thermodiffusion found most significant (in some cases > 30% E) when leaf-to-air difference coincides with relatively small across boundary layer; layer conductance large compared stomatal conductance; or low rate. also alters conditions required onset reverse transpiration, rate at uptake occurs.

Most ecosystems experience frequent cloud cover resulting in light that is predominantly diffuse rather than direct. Moreover, these cloudy conditions are often accompanied by rain results wet leaf surfaces. Despite this, our understanding of photosynthesis built upon measurements made on dry leaves experiencing direct light. Using a modified gas exchange setup, we measured the effects and wetting canopy species from tropical montane forest. We demonstrate significant variation species-level response to quality independent intensity. Some demonstrated 100% higher rates light, others had 15% greater Even at lower intensities, was equal under conditions. Leaf generally led decreased photosynthesis, particularly when surface with stomata became wet; however, there across species. Ultimately, ecosystem significantly altered environmental ubiquitous. Our help explain observation net can increase improve representation processes Earth systems models projected scenarios global climate change.
