Improvement of Ecological Footprint Model in National Nature Reserve Based on Net Primary Production (NPP) [PDF]

Sustainability, 2018
An increasing number of nature reserves are being invaded by various development and construction activities, such as energy, resources, and transportation facilities. The ecological footprint model, which enables a quantitative assessment of ecological sustainability, can assess whether human consumption at various spatial scales falls within the ...

Climatic change controls productivity variation in global grasslands. [PDF]

, 2016
Detection and identification of the impacts of climate change on ecosystems have been core issues in climate change research in recent years. In this study, we compared average annual values of the normalized difference vegetation index (NDVI) with ...

Seasonally and spatially varied controls of climatic factors on net primary productivity in alpine grasslands on the Tibetan Plateau

Global Ecology and Conservation, 2020
Vegetation net primary productivity (NPP) is a core parameter regulating carbon cycles of terrestrial ecosystem, which also has close relations with climates.

Estimating ocean net primary productivity from daily cycles of carbon biomass measured by profiling floats

Limnology and Oceanography Letters, 2023
The dependence of net primary productivity (NPP), a central metric in ecology and biogeochemistry, on sunlight drives daily cycles in carbon biomass in the ocean's euphotic zone. In this study, we infer NPP from the daily cycle of biomass.

Estimation of Global Vegetation Productivity from Global LAnd Surface Satellite Data

Remote Sensing, 2018
Accurately estimating vegetation productivity is important in research on terrestrial ecosystems, carbon cycles and climate change. Eight-day gross primary production (GPP) and annual net primary production (NPP) are contained in MODerate Resolution ...

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.

Tree-ring isotopes capture interannual vegetation productivity dynamics at the biome scale

Nature Communications, 2019
Historical and future trends in net primary productivity (NPP) and its sensitivity to global change are largely unknown because of the lack of long-term, high-resolution data.

Contrasting spatial variations between above and below-ground net primary productivity in global grasslands

Ecological Indicators
Grassland net primary productivity (NPP) plays a crucial role in global terrestrial carbon cycle and carbon balance. However, the spatial pattern and influencing factors of NPP and its components, especially the belowground net primary productivity (BNPP)

Nitrogen controls the net primary production of an alpine Kobresia meadow in the northern Qinghai‐Tibet Plateau

Ecology and Evolution, 2019
Net primary production (NPP) is a fundamental property of natural ecosystems. Understanding the temporal variations of NPP could provide new insights into the responses of communities to environmental factors.
