Convergence of potential net ecosystem production among contrasting C3 grasslands. [PDF]

Ecol Lett, 2013
AbstractMetabolic theory and body size constraints on biomass production and decomposition suggest that differences in the intrinsic potential net ecosystem production (NEPPOT) should be small among contrasting C3grasslands and therefore unable to explain the wide range in the annual apparent net ecosystem production (NEPAPP) reported by previous ...

Scaling net ecosystem production and net biome production over a heterogeneous region in the western United States [PDF]

Biogeosciences, 2007
Bottom-up scaling of net ecosystem production (NEP) and net biome production (NBP) was used to generate a carbon budget for a large heterogeneous region (the state of Oregon, 2.5×10⁵ km²) in the ...

Large-Scale Analysis of the Spatiotemporal Changes of Net Ecosystem Production in Hindu Kush Himalayan Region

Remote Sensing, 2021
The Hindu Kush Himalayan (HKH) region is one of the most ecologically vulnerable regions in the world. Several studies have been conducted on the dynamic changes of grassland in the HKH region, but few have considered grassland net ecosystem productivity

Thermal adaptation of net ecosystem exchange [PDF]

Biogeosciences, 2011
Thermal adaptation of gross primary production and ecosystem respiration has been well documented over broad thermal gradients. However, no study has examined their interaction as a function of temperature, i.e.

The role of net ecosystem productivity and of inventories in climate change research: the need for “net ecosystem productivity with harvest”, NEPH [PDF]

Forest Ecosystems, 2021
Abstract Background There is an urgent need for quantifying the terrestrial carbon sink in the context of global carbon emissions. However, neither the flux measurements, nor the national wood balances fulfil this purpose.

Nitrogen saturation and net ecosystem production [PDF]

Nature, 2008
Magnani et al. found that net carbon (C) sequestration of temperate and boreal forests is clearly driven by nitrogen (N) deposition. From the positive relationship between average net ecosystem production (NEP) and wet N deposition, the authors further conclude that "no signs of N saturation were apparent" in the studied forests and that this is ...

NET ECOSYSTEM PRODUCTION: A COMPREHENSIVE MEASURE OF NET CARBON ACCUMULATION BY ECOSYSTEMS [PDF]

Ecological Applications, 2002
The conceptual framework used by ecologists and biogeochemists must allow for accurate and clearly defined comparisons of carbon fluxes made with disparate techniques across a spectrum of temporal and spatial scales. Consistent with usage over the past four decades, we define “net ecosystem production” (NEP) as the net carbon accumulation by ecosystems.

Seasonal and Inter-Annual Variations in Carbon Dioxide Exchange over an Alpine Grassland in the Eastern Qinghai-Tibetan Plateau. [PDF]

PLoS ONE, 2016
This work analyzed carbon dioxide exchange and its controlling factors over an alpine grassland on the eastern Qinghai-Tibetan Plateau. The main results show that air temperature and photosynthetically active radiation are two dominant factors ...

Interannual Carbon Exchange Variability of Rain-fed Maize Fields in Northeast China and Its Influencing Factors

应用气象学报, 2023
Interannual variation in net ecosystem carbon production (NEP) plays an important role in the carbon cycle processes. An agricultural ecosystem may fluctuate between carbon net source and carbon sink, or it may remain neutral.

Methane emission offsets carbon dioxide uptake in a small productive lake

Limnology and Oceanography Letters, 2020
Here, we investigate the importance of net CH4 production and emissions in the carbon (C) budget of a small productive lake by monitoring CH4, CO2, and O2 for two consecutive years.
