Physicochemical and biological controls on primary and net community production across northeast Pacific seascapes
northeast Pacific seascapes Physicochemical biological controls
2014/11/28
The subarctic–subtropical transition zone in the North Pacific represents the second largest sink of
atmospheric carbon dioxide in the world ocean, yet the relative importance of physical and biologi...

Changes in the vertical distribution of primary production in response to land-based nitrogen loading。
Spring phytoplankton communities shaped by interannual weather variability and dispersal limitation: Mechanisms of climate change effects on key coastal primary producers
Spring phytoplankton communities shaped interannual weather variability dispersal limitation Mechanisms of climate change effects key coastal primary producers
2014/4/2
Spring bloom composition in the Baltic Sea, a partially ice-covered brackish coastal waterbody, is shaped by winter–spring weather conditions affecting the relative dominance of diatoms and a heteroge...
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...
Comparing Process-Based Net Primary Productivity Models in a Mediterranean Watershed
NPP Modelling Remote Sensing Percent Tree Cover Model Comparison CASA LPJ-GUESS
2014/4/22
The aim of this study was to compare the estimation capability of two different process-based NPP models (CASA and LPJGUESS) in a Mediterranean watershed. Remotely sensed data and climate time series ...
Severe droughts reduce estuarine primary productivity with cascading effects on higher trophic levels
higher trophic levels Severe droughts reduce estuarine
2014/4/4
Using a 10-yr time-series data set, we analyzed the effects of two severe droughts on water-quality and
ecosystem processes in a temperate, eutrophic estuary (Neuse River Estuary, North Carolina). Du...
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...
Top-down and bottom-up influences of jellyfish on primary productivity and planktonic assemblages
Top-down and bottom-up jellyfish on primary productivity planktonic assemblages
2014/4/17
A manipulative mesocosm experiment was done in a saline coastal lake in Australia to compare the top-down and bottom-up influences of jellyfish on primary production and planktonic assemblages. We hyp...
Nutrient enrichment differentially affects body sizes of primary consumers and predators in a detritus-based stream
Nutrient enrichment differentially affects body sizes predators
2014/4/17
We assessed how a 5-yr nutrient enrichment affected the responses of different size classes of primary
consumers and predators in a detritus-based headwater stream. We hypothesized that alterations i...
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...
