Driving Climatic Factors at Critical Plant Developmental Stages for Qinghai–Tibet Plateau Alpine Grassland Productivity

Remote Sensing, 2022
Determining the driving climatic factors at critical periods and potential legacy effects is crucial for grassland productivity predictions on the Qinghai–Tibet Plateau (QTP).

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

Management and climate variability effects on understory productivity of forest and savanna ecosystems in Oklahoma, USA

Ecosphere, 2021
The productivity of herbaceous and understory woody vegetation is critical for wildlife habitat, livestock forage, and biodiversity, and is influenced by both annual weather patterns and tree dominance.

An increase in livestock density increases forage nutritional value but decreases net primary production and annual forage nutritional yield in the alpine grassland of the Qinghai-Tibetan Plateau

Frontiers in Plant Science, 2022
Pasture biomass and quality are dependent on herbivore grazing and precipitation, but the responses of vegetation to the interactive effects of climate and grazing regimes remain unclear.

Warmer and wetter climate promotes net primary production in C4 grassland with additional enhancement by hay harvesting

Ecosphere, 2022
Grassland ecosystems provide essential services to society. To maintain ecosystem functions and services of grasslands under changing environments, it is critical to understand how grasslands respond and feedback to climate change.

Charge Independence and Charge Symmetry [PDF]

, 1994
Charge independence and charge symmetry are approximate symmetries of nature, violated by the perturbing effects of the mass difference between up and down quarks and by electromagnetic interactions.

Primary Productivity and Precipitation-Use Efficiency in Temperate Grassland in the Loess Plateau of China. [PDF]

PLoS ONE, 2015
Clarifying spatial variations in aboveground net primary productivity (ANPP) and precipitation-use efficiency (PUE) of grasslands is critical for effective prediction of the response of terrestrial ecosystem carbon and water cycle to future climate ...

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

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 ...

Seasonal patterns and controls on net ecosystem CO2 exchange in a boreal peatland complex [PDF]

, 1998
We measured seasonal patterns of net ecosystem exchange (NEE) of CO2 in a diverse peatland complex underlain by discontinuous permafrost in northern Manitoba, Canada, as part of the Boreal Ecosystems Atmosphere Study (BOREAS).

Above-ground biomass and productivity in a rain forest of eastern South America [PDF]

, 2008
: The dynamics of tropical forest woody plants was studied at the Nouragues Field Station, central French Guiana. Stem density, basal area, above-ground biomass and above-ground net primary productivity, including the contribution of litterfall, were ...
