Trends of Aboveground Net Primary Productivity of Patagonian Meadows, the Omitted Ecosystem in Desertification Studies [PDF]

Remote Sensing, 2023
The United Nations defines desertification as the loss of productivity in arid and semiarid environments. The extended steppes of Patagonia harbor small meadows whose compounded area is comparatively small, but their aboveground net primary production ...

Modeling switchgrass aboveground net primary productivity and evapotranspiration across Michigan [PDF]

, 2015
Switchgrass has been proposed as a biofuel feedstock in the US. Studies in the past decades have shown that switchgrass is able to produce sizable biomass with varied management practices.

Estimating aboveground net primary production in grasslands: A simulation approach

Ecological Modelling, 1986
Abstract A simulation model which reflected the seasonal dynamics of biomass in a North America mixed prairie was employed to evaluate methods of calculating aboveground net primary production from harvest data. The methods of calculating aboveground net primary production were evaluated under conditions with and without variability in the data.

Aboveground Rather Than Belowground Productivity Drives Variability in Miscanthus × giganteus Net Primary Productivity [PDF]

GCB Bioenergy
Quantifying the carbon (C) uptake of Miscanthus × giganteus (M × g) in both aboveground and belowground structures (e.g., net primary productivity (NPP)) and differences among methodological approaches is crucial.

Aboveground Biomass and Net Primary Production Along a Virginia Barrier Island Dune Chronosequence [PDF]

, 1994
Aboveground biomass was examined along a chronosequence of dune communities on Hog Island, a Virginia Coast Reserve LTER site. The dominant species were Ammophila breviligulata and Spartina patens. Aboveground biomass was harvested monthly from ten quadrats on dunes 6, 24, 36, and 120 years old.

Temperature sensitivity in aboveground net primary productivity in semi-arid grasslands [PDF]

, 2014
Although climate models forecast warmer temperatures with a high degree of certainty, precipitation is the primary driver of aboveground net primary productivity (ANPP) in most grasslands. In contrast, variations in temperature seldom are related to patterns of ANPP.

Regional contingencies in the relationship between aboveground biomass and litter in the world’s grasslands [PDF]

, 2013
Based on regional-scale studies, aboveground production and litter decomposition are thought to positively covary, because they are driven by shared biotic and climatic factors.

Asymmetric responses of primary productivity to altered precipitation simulated by ecosystem models across three long-term grassland sites [PDF]

Biogeosciences, 2018
Field measurements of aboveground net primary productivity (ANPP) in temperate grasslands suggest that both positive and negative asymmetric responses to changes in precipitation (P) may occur.
