Dominant Species Drive Biomass and Diversity Responses to Nutrient Inputs [PDF]

Ecology and Evolution
Global change is enriching terrestrial ecosystems with multiple nutrients and amplifying interannual variation in precipitation. Grassland productivity may be co‐limited by combinations of nitrogen (N), phosphorus (P), and potassium (K).

Space-time quantification of aboveground net primary productivity service supply capacity in high Andean bofedales using remote sensors [PDF]

Journal of Water and Land Development, 2023
The aboveground net primary productivity ( ANPP) of bofedales is one of the most important indicators for the provision of ecosystem services in the high Andean areas. In the case of bofedales, the evaluation of the ANPP supply capacity as a service on a

Estimation of aboveground net primary productivity in secondary tropical dry forests using the Carnegie–Ames–Stanford approach (CASA) model

Environmental Research Letters, 2016
Although tropical dry forests (TDFs) cover roughly 42% of all tropical ecosystems, extensive deforestation and habitat fragmentation pose important limitations for their conservation and restoration worldwide.

Functional Groups Dominate Aboveground Net Primary Production under Long-Term Nutrient Additions in a Tibetan Alpine Meadow

Plants
Anthropogenic nutrient additions are influencing the structure and function of alpine grassland ecosystems. However, the underlying mechanisms of the direct and indirect effects of nutrient additions on aboveground net primary productivity (ANPP) are not

Detecting and modeling topography‐induced differences in plant productivity across a grassland ecosystem gradient

Ecosphere
Understanding spatial variation in grassland productivity is critical for ecological modeling and management. The Great Plains of North America, a vast grassland region east of the Rocky Mountains, exhibits strong gradients in aboveground net primary ...

A Decade of Rainfall Manipulation Reveals Growing-Season Aridity as a Key Determinant of Grassland Productivity and Stability. [PDF]

Glob Chang Biol
Changing rainfall patterns and rising temperatures threaten the diversity and functioning of grassland ecosystems. Using data from a 10‐year manipulation experiment, we show that productivity is most strongly related to growing season aridity (precipitation/potential evapotranspiration, P/PET).

Seed mixes of intermediate grass:forb ratio create vegetation of greater ecosystem service provision in restorations. [PDF]

Ecol Appl
Abstract Restoring pollination services using forb‐dense seed mixes is seen as a possible way to mitigate global pollinator decline. Research is needed on whether this management factor impacts other ecosystem services that could be influenced by greater emphasis on forbs than grasses in seed mixes.

Nitrogen dynamics 35 years after stand‐replacing fire: Aboveground pools grow as surface soil pools remain unchanged [PDF]

Ecology.
Abstract Natural disturbances induce variable recovery pathways, and long‐term studies are key to understanding how that variability affects ecosystem function over time and across space. In subalpine forests, high‐severity wildfires produce high variability in postfire tree density, but how this variability relates to nitrogen (N) cycling remains ...

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.

Plant cover associated with aboveground net primary productivity (ANPP) mediates insect community composition in steppes of Northwest China [PDF]

Journal of Asia-Pacific Entomology, 2018
Abstract Temperate steppe is one of the most important natural habitats for the conservation of arthropod and bird biodiversity across the Eurasian Tectonic Plate. Since 1950, fragmentation of the steppe habitat has caused a loss of biodiversity and degradation of the species communities found in natural steppe.
