Response of vegetation to drought time-scales across global land biomes.
We evaluated the response of the Earth land biomes to drought by correlating a drought index with three global indicators of vegetation activity and growth: vegetation indices from satellite imagery, tree-ring growth series, and Aboveground Net Primary Production (ANPP) records. Arid and humid biomes are both affected by drought, and we suggest that the persistence of the water deficit (i.e., t...

متن کاملHeat Response of Global Vegetation Biomes to Ongoing Climate Warming Based on Remote Sensing
Research is needed by global change scientists on how global vegetation biomes respond to ongoing climate warming. To address this issue, we selected study sites with significant climate warming for diverse vegetation biomes, and used global gridded temperature and remote sensing data over the past 32 years (1982–2013). The results suggested that climate warming in areas above approximately 60◦...
متن کاملStomatal Function across Temporal and Spatial Scales: Deep-Time Trends, Land-Atmosphere Coupling and Global Models.
The colonization of land by plants and their interaction with biogeochemical and atmospheric processes transformed continental climate and hydrology. Stomata, which evolved to optimize the biological economics of plant carbon uptake in exchange for water loss, play a crucial role in large-scale environmental processes by maintaining a connection between deep soil water reservoirs and the atmosp...
متن کاملFrom leaf to forests: Measuring vegetation water stress across scales
Vegetation water stress significantly affects agricultural and tropical forest canopies. Water shortages in crops influence plant water dynamics, reduces primary production and might eventually lead to plant death. Tropical forests are essential part of global carbon and water cycle. Continuing drying of e.g. the Amazon rainforest might accelerate climate change through carbon losses and changi...
