Responses of net ecosystem CO2 exchange to nitrogen fertilization in experimentally manipulated grassland ecosystems

Agricultural and Forest Meteorology, 2009
Nitrogen (N) addition enhances primary productivity of terrestrial ecosystems. However, the effects of N fertilization and/or deposition on net ecosystem CO2 exchange (NEE) are not fully understood. The effects of N on NEE were investigated in two experimental cheatgrass ecosystems in Ecologically Controlled Enclosed Lysimeter Laboratories (EcoCELLs ...

Spring drought regulates summer net ecosystem CO2 exchange in a sagebrush-steppe ecosystem

Agricultural and Forest Meteorology, 2008
Abstract Climate, as reflected by seasonal variations in precipitation and temperature, plays a critical role in ecosystem productivity and composition in the Western US and other arid regions. This study was conducted in the sagebrush-steppe ecosystem co-dominated by mountain big sagebrush ( Artemisia tridentata var.

Net ecosystem CO2 exchange and carbon cycling in tropical lowland flooded rice ecosystem

Nutrient Cycling in Agroecosystems, 2013
The seasonal fluxes of CO2 and its characteristics with relation to environmental variables were investigated under tropical lowland flooded rice paddies employing the open path eddy covariance technique. The seasonal net ecosystem carbon budget was quantified by empirical modelling approach.

Observation and Modeling of Net Ecosystem Carbon Exchange Over Canopy

2016
Eddy covariance, which is the most common micrometeorological flux measurement method, can estimate ecosystem-scale and fine time-resolution carbon dioxide (CO2) exchange between the upper vegetation surface and atmosphere. Given no lateral CO2 advection, the sum of eddy covariance measurements and CO2 storage in the underlying air represents net ...

Variations in net ecosystem exchange of carbon dioxide in a boreal mire

2007
[1] In mires, which occupy large areas of the boreal region, net ecosystem CO2 exchange (NEE) rates vary significantly over various timescales. In order to examine the effect of one of the most influencing variables, the water table depth, on NEE the general ecosystem model GUESS-ROMUL was modified to predict mire daily CO2 exchange rates. A simulation
