Study about Top-Down and Bottom-Up Controls in Regulating the Phytoplankton Biomass in a Eutrophic Reservoir in Northeastern Brazil
Chlorophyll a Nutrients Zooplankton Tropical Regions
2013/3/19
This study aims to analyze the effects of nutrients and predation by zooplankton on phytoplankton biomass (chlorophyll a) in a eutrophic reservoir in Brazil (Apipucos Reservoir, State of Pernambuco), ...
Effects of environmental conditions on the seasonal distribution of phytoplankton biomass in the North Sea
environmental conditions the seasonal distribution phytoplankton biomass in the North Sea
2014/4/18
We study the spatial and seasonal variability of phytoplankton biomass (as phytoplankton color) in relation to the environmental conditions in the North Sea using data from the Continuous Plankton Rec...
Why are diverse relationships observed between phytoplankton biomass and transport time?
diverse relationships observed ytoplankton
2014/4/17
Transport time scales such as flushing time and residence time are often used to explain variability in
phytoplankton biomass. In many cases, empirical data are consistent with a positive phytoplankt...

Influence of water-column depth and mixing on phytoplankton biomass, community composition, and nutrients
Influence of water-column depth mixing on phytoplankton biomass community composition nutrients
2014/4/21
We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separate and combined effe...

A long-term chlorophyll dataset reveals regime shift in North Sea phytoplankton biomass unconnected to nutrient levels
A long-term chlorophyll dataset reveals regime shift in North Sea phytoplankton biomass unconnected nutrient levels
2014/4/23
During the 1980s, a rapid increase in the Phytoplankton Colour Index (PCI), a semiquantitative visual estimate of algal biomass, was observed in the North Sea as part of a regionwide regime shift. Two...
Long-term temporal and spatial trends in phytoplankton biomass and class-level taxonomic composition in the hydrologically variable Neuse-Pamlico estuarine continuum, North Carolina, U.S.A.
Long-term temporal spatial trends phytoplankton biomass class-level taxonomic composition hydrologically variable Neuse-Pamlico estuarine continuum North Carolina U.S.A.
2014/5/4
Phytoplankton diagnostic photopigments in near-surface waters (~0.5 m) were identified and quantified by high-performance liquid chromatography beginning in April 1994 in the Neuse River Estuary and i...
Effects of atmospheric nitrogen deposition on nutrient limitation and phytoplankton biomass in unproductive Swedish lakes
atmospheric nitrogen deposition nutrient limitation phytoplankton biomass unproductive Swedish lakes
2014/5/9
We used chemical data (3,907 lakes) and phytoplankton biomass (chlorophyll a) data (225 lakes) from Swedish lake monitoring programs to assess the effects of atmospheric nitrogen (N) deposition on nut...
Coupling of epipelagic and mesopelagic heterotrophic picoplankton production to phytoplankton biomass in the Antarctic polar frontal region
epipelagic mesopelagic heterotrophic picoplankton production phytoplankton biomass Antarctic polar frontal region
2014/5/19
We assessed relationships between phytoplankton standing stock, measured as chlorophyll a (Chl a), primary production (PP), and heterotrophic picoplankton production (HPP), in the epipelagic zone (0-1...
Top-down control of phytoplankton biomass and community structure in the monsoonal Arabian Sea
Top-down control phytoplankton biomass community structure monsoonal Arabian Sea
2014/5/26
During the 1995 monsoons, phytoplankton biomass was low over large areas of the Arabian Sea in spite of often high concentrations of inorganic nutrients, characteristics typical of high-nutrient, lowc...
