Primary production by marine phytoplankton is one of the largest fluxes carbon on our planet. In past few decades, considerable progress has been made in estimating global primary at high spatial and temporal scales combining situ measurements with remote-sensing observations biomass. One major challenges this approach lies assignment appropriate model parameters that define photosynthetic response to light field. present study, a database photosynthesis versus irradiance (P-I) 20-year...

Benguela Current represent fi ve Large Marine Ecosystems (LMEs) associated with eastern boundary upwelling regimes (Figure 1).LMEs are characterized by distinct bathymetry, hydrography, productivity, and trophically dependent populations.Most of the global ocean pollution, overexploitation, coastal habitat alteration occurs within LME waters.The highly productive account for a large fraction sheries production 2), but similar to all other marine environments, increasingly susceptible...

Summary We used catalysed reported deposition – fluorescence in situ hybridization (CARD‐FISH) to analyse changes the abundance of bacterial groups Alphaproteobacteria , Gammaproteobacteria and Bacteroidetes, hydrocarbon‐degrading Cycloclasticus bacteria mesocosms that had received polycyclic aromatic hydrocarbons (PAHs) additions. The effects PAHs were assessed under four contrasting hydrographic conditions coastal upwelling system Rías Baixas: winter mixing, spring bloom, summer...
We examined large volumes of seawater under the microscope to explore limits phytoplankton diversity in a highly dynamic coastal ecosystem. Our analysis showed that conventional sample severely underestimate species richness these communities. The number observed doubled after 10-fold increase volume, implying estimates depend critically on sampling effort. volume needed detect 90% varied between 0.25 and 1 L depending concentration biomass.

Red tides are conspicuous in the upwelling system of Galicia (NW Iberian Peninsula). At present, there conflicting hypotheses about generation site these phytoplankton assemblages. It is interesting to know whether rias can be sites red tide formation or if they act only as accumulation populations advected from shelf waters. A study Ría de Vigo, carried out during late September 1990, showed development a assemblage, composed Alexandrium affinis, Ceraiium fusus and Gymnodinium catenaium, 2...

The number of species autotrophic communities can increase ecosystem productivity through complementarity or a selection effect which occurs when the biomass community approaches monoculture most productive species. Here we explore resource supply on marine primary under premise that high local richness phytoplankton increases use transient Using concurrent measurements structure, nitrate fluxes into euphotic zone and from temperate coastal ecosystem, find observed productivities are best...
ABSTRACT For decades, identifying pico‐ and nanoeukaryotic plankton has been challenging due to their small size, leaving a significant gap in our knowledge of composition dynamics comparison with larger counterparts.
