Long term picoplankton dynamics in a warm-monomictic, tropical high altitude lake

Journal of Limnology, 2009
Long term analyses of the microbial loop, centred on the picoplankton dynamics, were carried out over a five-year (1998 to 2002) period in Lake Alchichica (Puebla, Mexico), a high altitude tropical athalassohaline lake.

Growth and Fatty Acid Composition of Marine Microalga Nannochloropsis SP in Medium Enriched with Magnesium [PDF]

, 2010
Micro-algae are to be an attractive way to produce bio-diesel due to high photosynthetic yields and lipid accumulation in cells. This high productivity combined with possibility to uptake CO2 stimulated its utilization as a biological mitigation method ...

Size structure of the planktonic community in microcosms with different levels of turbulence

Scientia Marina, 2005
The evolution of a natural plankton community in two microcosms with well-differentiated turbulence levels (10-3 W m-3 and 10-1 W m-3) was compared during artificially-generated blooms.

3-D Ultrastructure of O. tauri: Electron Cryotomography of an Entire Eukaryotic Cell [PDF]

, 2007
The hallmark of eukaryotic cells is their segregation of key biological functions into discrete, membrane-bound organelles. Creating accurate models of their ultrastructural complexity has been difficult in part because of the limited resolution of light

Picocyanobacteria distribution in the Ebro Estuary (Spain) [PDF]

, 2005
The stratified estuary of the Ebro River is located on the Mediterranean coast of Spain. From samples obtained in 6 sampling campaigns between July 1999 and February 2000 from the last 18 km of Ebro River, the abundance of picocyanobacteria was estimated

Effect of El Nino southern oscillation events on the distribution and abundance of phytoplankton in the Western Pacific Tropical Ocean along 165°E [PDF]

, 1992
The distribution of physical and chemical parameters and their impact on the biomass and abundance of phytoplankton in the Western Pacific ocean were compared in two opposing situations : the El Nino Southern Oscillation (ENSO) event of 1987 and the no ...

Nanoplanktonic diatoms are globally overlooked but play a role in spring blooms and carbon export

Nature Communications, 2018
Diatoms are major oceanic primary producers, but some species belonging to the nano- and even picoplankton size are poorly characterized. Here the authors describe a massive spring bloom of the smallest known diatom in the Mediterranean Sea and reveal ...

Growth and specific P-uptake rates of bacterial and phytoplanktonic communities in the Southeast Pacific (BIOSOPE cruise) [PDF]

Biogeosciences, 2007
Predicting heterotrophic bacteria and phytoplankton specific growth rates (&mu; ) is of great scientific interest. Many methods have been developed in order to assess bacterial or phytoplankton &mu;.
