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...
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...
Patterns in microphytobenthic primary productivity: Species-specific variation in migratory rhythms and photosynthesis in mixed-species biofilms
microphytobenthos primary productivity Species-specific variation migratory rhythms photosynthesis mixed-species biofilms
2014/5/9
The importance of temporal changes in the vertical distribution of microphytobenthic algae on the overall functioning of intertidal biofilms were investigated with low-temperature scanning electron mi...
Climatic forcing and primary productivity in a subalpine lake: Interannual variability as a natural experiment
Climatic forcing primary productivity a subalpine lake Interannual variability natural experiment
2014/5/14
We analyzed a 42-yr record of primary productivity in small, subalpine Castle Lake to determine how climatic variability might influence lake primary productivity. A Pacific Decadal Oscillation (PDO) ...
Primary productivity of reef-building crustose coralline algae
crustose coralline algae Primary
2014/5/21
The primary productivity of four species of crustose coralline algae was measured as a function of depth (0–18
m) and irradiance on samples collected from and growing upon the windward coral reef at ...
Changes in primary productivity and chlorophyll a in response to iron fertilization in the Southern Polar Frontal Zone

2014/5/26
EisenEx—the second in situ iron enrichment experiment in the Southern Ocean—was performed in the Atlantic sector over 3 weeks in November 2000 with the overarching goal to test the hypothesi...
Use of a reduced-gravity model to evaluate present and past primary productivity in the tropical open ocean

2014/6/10
Upwelling predicted by a reduced-gravity model is compared with remotely sensed primary productivity data through the tropical Atlantic and Pacific. The model upper layer thickness, an indicator of ve...
