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...
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. ...
PRIMARY PRODUCTION AND RAIN USE EFFICIENCY ACROSS A PRECIPITATION GRADIENT ON THE MONGOLIA PLATEAU
ANPP arid and semiarid land ecosystem management Eurasian Steppe Inner Mongolia grassland mean annual precipitation nitrogen addition plant functional group composition rain-use efficiency
2015/2/4
Understanding how the aboveground net primary production (ANPP) of arid and semiarid ecosystems of the world responds to variations in precipitation is crucial for assessing the impacts of climate cha...
Changes in the vertical distribution of primary production in response to land-based nitrogen loading
Terrestrial nitrogen load production

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...

Partitioning of primary production among giant kelp (Macrocystis pyrifera), understory macroalgae, and phytoplankton on a temperate reef
giant kelp understory macroalgae phytoplankton
2014/4/4
We experimentally investigated the response of phytoplankton and understory macroalgae to canopies of giant
kelp, Macrocystis pyrifera, by following changes in their biomass and net primary productio...
Terrestrial organic matter and light penetration: Effects on bacterial and primary production in lakes
Terrestrial organic matter light penetration on bacterial primary production in lakes
2014/4/17
We investigated productivity at the basal trophic level in 15 unproductive lakes in a gradient ranging from clear-water to brown-water (humic) lakes in northern Sweden. Primary production and bacteria...
Geochemical processes and chemosynthetic primary production in different thiotrophic mats of the Ha˚kon Mosby Mud Volcano (Barents Sea)
Geochemical processes chemosynthetic primary production different thiotrophic mats of the Ha˚ kon Mosby Mud Volcano
2014/4/16
We have investigated if in a cold seep methane or sulfide is used for chemosynthetic primary production and if
significant amounts of the sulfide produced by anaerobic oxidation of methane are oxidiz...
Direct and indirect coupling of primary production and diel nitrate dynamics in a subtropical spring-fed river
primary production iel nitrate dynamics
2014/4/16
We used high-frequency in situ measurements of nitrate (NO{

) and dissolved oxygen (DO) from the springfed Ichetucknee River, Florida, to derive multiple independent estimates of assimilatory nitr...
Primary production during nutrient-induced blooms at elevated CO2 concentrations
Primary production nutrient-induced blooms elevated CO2 concentrations
2010/1/20
A CO2 enrichment experiment (PeECE III) was carried out in 9 mesocosms in which the seawater carbonate system was manipulated to achieve three different levels of pCO2. At the onset of the experimenta...
Light limitation of primary production in high latitude reservoirs
high latitude reservoirs Light limitation
2009/5/18
To explore the effects of vertical mixing on the primary production in a northern reservoir, a Lagrangian particle dispersion model was coupled to a 1-D reservoir model where the vertical mixing was c...

Thresholds of gross primary production metabolic balance marine planktonic communities
2014/4/18
The notion that less productive marine planktonic communities tend to be heterotrophic was tested by synthesizing reported estimates of the relationships between the net community production or commun...
