Ecovoltaics in an increasingly water-limited world: An ecological ...
2 天之前 · This is because, unlike carbon uptake, water loss (evapotranspiration) from ecosystems tends to be greatest in the afternoon, when air temperatures and VPD are also high. 35 In fact, many field studies have documented recovery in plant water status (potentially alleviating stress) during periods of midday/afternoon shade arising from cloud ...
Heat and Drought Have Exacerbated the Midday Depression …
2024年9月7日 · High temperatures directly affect the stomatal conductance and photosynthetic capacity of plants, leading to a reduction in carbon assimilation at midday. The drought conditions throughout 2020 also exacerbated the scarcity of water resources, with the region receiving only 852.5 mm of precipitation from April to December, which was 22.9% less ...
Widespread and complex drought effects on vegetation ... - Nature
2023年8月15日 · Here, we study vegetation drought responses related to photosynthesis, evaporation, and vegetation water content using remotely sensed data, and we isolate physiological responses using a machine...
Drought can be more critical in the shade than in the sun: a field ...
2002年6月24日 · In our study, the value of g wv was significantly reduced with the onset of drought both in the sun and in the shade, especially at midday . This reduced g wv led to a sharp decrease of net photosynthesis both in the sun and in the shade.
New-generation geostationary satellite reveals widespread midday ...
2023年8月2日 · Our findings reveal a widespread midday and afternoon depression of photosynthesis in dryland ecosystems during the heatwave, a phenomenon not discernible through polar-orbiting satellite observations.
Rice feeds half the world. Climate change's droughts and floods …
2021年9月24日 · Under a midday summer sun in California’s Sacramento Valley, rice farmer Peter Rystrom walks across a dusty, barren plot of land, parched soil crunching beneath each step.
Drought survival is positively associated with high turgor loss …
2020年1月6日 · We directly related them to the species’ comparative whole-plant drought survival and midday leaf water potentials under drought (Ψ MD) assessed in a common garden drought experiment, and to species moisture association.
The best time to water your plants during a heatwave
2018年7月4日 · Avoid full sun. What is generally agreed is that plants should not be watered while in full sun. The notion that wet leaves on sunny days cause scorch in plants was disproved nearly ten years...
structural changes under severe drought. We find similar patterns of physio-logical drought response using simulations from a soil–plant–atmosphere
Climate influence on compound solar and wind droughts in …
2023年11月10日 · With our drought definition, solar radiation droughts occur more often in southern REZs, and while these events may matter to plant owners and regional generation, understanding how important...
