An experimental test of climate change effects in northern lakes: Increasing allochthonous organic matter and warming alters autumn primary production
ClimateChange lakes production GPP cDOM
2021/7/26
Climate changes are predicted to influence gross primary production (GPP) of lakes directly through warming and indirectly through increased loads of allochthonous coloured dissolved organic matter (c...
Does the net primary production converge across six temperate forest types under the same climate?
Carbon allocation Elemental stoichiometry Net primary production Nutrient availability Temperate forest
2024/3/8
Quantifying net primary production (NPP) and its allocation is essential for understanding and modeling the carbon (C) cycling in forest ecosystems. We used biometry-based measurements to examine the ...
ESTIMATING GROSS PRIMARY PRODUCTION IN CROPLAND WITH HIGH SPATIAL AND TEMPORAL SCALE REMOTE SENSING DATA
Cropland GOES-13 geostationary Gross Primary Production Landsat NDV MODIS NDVI/EVI product carbon cycle Photosynthesis active radiation (PAR)
2018/5/15
Satellite remote sensing data provide spatially continuous and temporally repetitive observations of land surfaces, and they have become increasingly important for monitoring large region of vegetatio...
LOCAL SCALE MAPPING OF NET PRIMARY PRODUCTION IN TROPICAL RAIN FOREST USING MODIS SATELLITE DATA
Local scale Mapping Net Primary Production MODIS Tropical Rain Forest
2016/1/3
Satellite data from Moderate Resolution Imaging Radiometer (MODIS) is currently being used to extract net primary production (NPP) at global scale. Over the years, small scale on-ground flux tower mea...
Salt Marsh Primary Production and Its Responses to Relative Sea Level and Nutrients in Estuaries at Plum Island, Massachusetts, and North Inlet, SouthCarolina, USA
Primary Production Relative Sea Level
2015/7/16
Feedbacks between flooding and plant growth that help to stabilize marshes against rising sea level are being investigated in estuaries at Plum Island, Massachusetts, and North Inlet, South Carolina. ...
SPACEBORNE QUANTITATIVE ASSESSMENT OF PRIMARY PRODUCTION VARIATIONS IN THE ARCTIC OCEAN OVER THE PREVIOUS DECADE
Arctic Ocean Primary Production
2015/5/7
Spaceborne one month averaged data, predominantly from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) and partly from the Moderate Resolution Imaging Spectroradiometer (MODIS), were used to inv...
RELATIONSHIPS BETWEEN PRIMARY PRODUCTION AND CROP YIELDS IN SEMI-ARID AND ARID IRRIGATED AGRO-ECOSYSTEMS
Agriculture Crop GIS Analysis
2015/5/6
In semi-arid areas within the MENA region, food security problems are the main problematic imposed. Remote sensing can be a promising too early diagnose food shortages and further prevent the popula...
PRIMARY PRODUCTION AND RAIN USE EFFICIENCY ACROSS A PRECIPITATION GRADIENT ON THE MONGOLIA PLATEAU

Changes in the vertical distribution of primary production in response to land-based nitrogen loading。
Seasonal rates of benthic primary production in a Greenland fjord measured by aquatic eddy correlation
benthic aquatic eddy correlation
2014/10/16
We present the first year-round estimates of benthic primary production at four contrasting shallow (3–22 m
depth) benthic habitats in a southwest Greenland fjord. In situ measurements were performed...
Advective transport of diazotrophs and importance of their nitrogen fixation on new and primary production in the western Pacific warm pool
Advective transport diazotrophs importance their nitrogen fixation new primary production in the western Pacific warm pool
2014/4/2
The western Pacific warm pool (WPWP) is a region of low nutrient and chlorophyll concentrations in which new production is generally considered to be supported by upward fluxes of nitrate from the dee...
