Water response of ecosystem respiration regulates future projection of net ecosystem productivity in a semiarid grassland

Recent evidences show that terrestrial biogeochemical models have large uncertainty in estimating climate-change effect on grassland net ecosystem productivity (NEP), which is defined as the difference between gross ecosystem photosynthesis (GEP) and respiration (ER). It remains unclear that whether GEP or ER limits the model capability to simulate NEP responses […]

Rooting depth varies differentially in trees and grasses as a function of mean annual rainfall in an African savanna

A significant fraction of the terrestrial biosphere comprises biomes containing tree–grass mixtures. Forecasting vegetation dynamics in these environments requires a thorough understanding of how trees and grasses use and compete for key belowground resources. There is disagreement about the extent to which tree–grass vertical root separation occurs in these ecosystems, […]

Functional traits along a transect

Functional traits, which usually develop over evolutionary time‐scales to maximize plant survivorship and functional performances in changing environment, are important indices to explore how ecosystems respond and adapt to a changing environment. Many ecologists have argued that identifying regional to global‐scale patterns in functional traits, at organismal to ecosystem scales, […]

Fuel-reduction management alters plant composition, carbon and nitrogen pools, and soil thaw in Alaskan boreal forest

Increasing wildfire activity in Alaska’s boreal forests has led to greater fuel reduction management. Management has been implemented to reduce wildfire spread, but the ecological impacts of these practices are poorly known. We quantified the effects of handthinning and shearblading on above- and belowground stand characteristics, plant species composition, carbon […]
