modeled the contribution of smaller particles to the mussel diet, and, for the first time, showed that picoplankton
could be a significant proportion of the total net intake and contribute 13%-28% of the energy needed for tissue and shell growth in mussels.
In this study, with a marine picoplankton
assemblage collected at eastern North Pacific, a 38.5 kbp fragment containing an archaeal 16S rRNA gene was isolated for the first time.
Introduction of single cell analysis by flow cytometry and pigment analysis by HPLC enabled easy quantification of small-size phytoplankton (picoplankton
, <2 [micro]m), which are dominant in the less productive offshore waters (Li et al., 1993; Partensky et al., 1993), such as subtropical ocean gyres and the Mediterranean (Li et al.1993; Bell & Kalff 2001; Uysal, 2006).
A five-year study of autotrophic winter picoplankton
in Lake Balaton, Hungary.
Ciliate grazing on picoplankton
in a eutrophic reservoir during the summer phytoplankton maximum: a study at the species and community level.
Short-term changes of protozoan control on autotrophic picoplankton
in an oligo-mesotrophic lake.
Pigment information was used to calculate phytoplankton size fractions (micro, nano, and picoplankton
) according to Uitz et al.
Oxygenic prokaryotic photoautotrophs (Cyanobacteria) were estimated to constitute about 10% of the total ocean marine picoplankton
in the upper 200 m .
abundances in the western tropical Pacific Ocean during the 1992 El Nino year: results from flow cytometry.
This year's 31 articles include discussion of eukaryotic picoplankton
in surface oceans, prospects for the future using genomics and proteomics in clinical microbiology, how viruses and toxins disassemble to enter host cells, gene regulation in Borrelia burgdorferi, and what has been learned from synthetic poliovirus and other designer viruses.
A SeaBird autofire rosette was used to collect water for analyses of chlorophyll a, nutrient concentrations, and photosynthetic picoplankton
The application of the organic paleothermometer [TEX.sub.86] (based on the distribution of species of membrane lipids of the marine picoplankton
