Short Duration Grazing at the Texas Experimental Ranch: Effects on Aboveground Net Primary Production and Seasonal Growth Dynamics

, 1982
The effects of short duration grazing on aboveground net primary productivity (ANPP) and seasonal growth dynamics were evaluated. Total ANPP was estimated to be 234 g/m2 in 1978 in the ungrazed control plot as compared to 330 g/m2 in the grazed treatment

Effects of Soil Moisture and Atmospheric Vapor Pressure Deficit on the Temporal Variability of Productivity in Eurasian Grasslands

Remote Sensing
The grasslands in high-latitude areas are sensitive to climate warming and drought. However, the drought stress effect on the long-term variability of grassland productivity at the continental scale still hinders our understanding.

Global evidence on nitrogen saturation of terrestrial ecosystem net primary productivity

Environmental Research Letters, 2016
The continually increasing nitrogen (N) deposition is expected to increase ecosystem aboveground net primary production (ANPP) until it exceeds plant N demand, causing a nonlinear response and N saturation for ANPP.

Net primary productivity and its partitioning in response to precipitation gradient in an alpine meadow

, 2017
The dynamics of net primary productivity (NPP) and its partitioning to the aboveground versus belowground are of fundamental importance to understand carbon cycling and its feedback to climate change. However, the responses of NPP and its partitioning to

Aboveground net primary productivity not CO2 exchange remain stable under three timing of extreme drought in a semi-arid steppe.

PLoS ONE, 2019
Precipitation patterns are expected to change in the semi-arid region within the next decades, with projected increasing in extreme drought events. Meanwhile, the timing of extreme drought also shows great uncertainty, suggesting that the timing of ...

Testing nitrogen and water co-limitation of primary productivity in a temperate steppe

, 2018
Background and aims: Primary productivity in the temperate steppe is assumed to be co-limited by nitrogen (N) and water availability, but empirical evidence is scarce. We examined the N and water limitation status of primary productivity from the species

Frequency distributions of aboveground net primary productivity (ANPP) of alpine grasslands on the Northern Tibetan Plateau (NTP).

, 2015
ANPP is equal to the peak aboveground biomass (AGB). AM = alpine meadow; AS = alpine steppe; ADS = alpine desert-steppe. FG = free grazed; GE = grazed excluded.

Spatiotemporal dynamics of aboveground primary productivity along a precipitation gradient in Chinese temperate grassland

, 2007
Investigating the spatial and temporal variance in productivity along natural precipitation gradients is one of the most efficient approaches to improve understanding of how ecosystems respond to climate change.
