Viral abundance in aquatic systems:a comparison between marine and fresh waters
TLDR
The virusto-bacteria ratio was significantly higher in freshwater than marine environments, and there were significantly more bacteria per unit chlorophyll in the authors' freshwater samples, suggesting that this difference is related to the increased dependence of freshwater bacteria on allochthonous material relative to marine systems, as well as the increased relative importance of photosynthetic cyanobacteria in lakes. Expand
Empirical relationships between bacterial abundance and chlorophyll concentration in fresh and marine waters
TLDR
A strong, positive empirical relationship was found between bacterial abundance and chlorophyll concentration in fresh and marine waters, and it is suggested that planktonic bacteria and algae are tightly linked in lakes and the sea. Expand
Microorganisms in the accreted ice of Lake Vostok, Antarctica.
TLDR
Analysis of accreted ice data suggest that Lake Vostok may contain viable microorganisms, and at least a portion of the microbial assemblage was viable, as determined by the respiration of carbon-14-labeled acetate and glucose substrates during incubations at 3 degrees C and 1 atmosphere. Expand
The summer metabolic balance in the epilimnion of southeastern Quebec lakes
On the basis of data collected in Quebec lakes, del Giorgio and Peters (1994) and Carignan et al. (2000) have come to opposite conclusions regarding the metabolic balance between heterotrophy andExpand
UNCOUPLING OF BACTERIA AND PHYTOPLANKTON DURING THE AUSTRAL SPRING BLOOM IN GERLACHE STRAIT, ANTARCTIC PENINSULA
TLDR
Grazing was the apparent cause, although biomass limitation of the bacteria due to lack of resources may be the ultimate cause of the uncoupling of bacterial and phytoplanktonic communities in these habitats. Expand
Tricho-desmium blooms and new nitrogen in the North Pacific gyre
A method of protecting plant life from injury due to frost or sub-freezing temperatures which comprises applying to the plant an effective, but non-phytotoxic amount, having regard to the plant beingExpand
Flow cytometric determination of bacterial abundance in lake plankton with the green nucleic acid stain SYTO 13
TLDR
The precision of cytometric counts was 10-fold higher than corresponding epifluorescence bacterial counts, and the sample processing time is decreased by 10-15-fold relative to the epIFluorescence technique. Expand
Bacterial Grazing by Planktonic Lake Algae
TLDR
Six common species of lake algae were found to ingest bacteria and a large biomass of Dinobryon species removed more bacteria from the water column of a lake than crustaceans, rotifers, and ciliates combined. Expand
Viral and bacterial dynamics in Arctic sea ice during the spring algal bloom near Resolute
High virus counts were found in Arctic sea ice samples taken during the spring ice algal bloom near Resolute, Northwest Territories, Canada. Viral abundances in the sea ice ranged from 3.7 X 10"Expand
Critical depth and marine primary production
The concept of critical depth, as formulated by Sverdrup (J. Cim. perm. int. Explor. Mer. 18, 287 (1953)) to explain the onset of the spring bloom of phytoplankton, is discussed. SimplifyingExpand
