The ecology of heterotrophic microflagellates
TL;DR: The wide variety of unicellular, phagotrophic eucaryotes known collectively as heterotrophic microflagellates has recently attracted much attention particularly among biological oceanographers.
Journal ArticleDOI
Technique for enumeration of heterotrophic and phototrophic nanoplankton, using epifluorescence microscopy, and comparison with other procedures
TL;DR: Comparison with existing epifluorescence techniques for counting heterotrophic and phototrophic nanoplankton shows that primulin provides more accurate counts of these populations than the fluorescein isothiocyanate or proflavine techniques.
Journal ArticleDOI
Ecology of Free-Living Amoebae
TL;DR: Small free-living amoebae (FLA) are the main predators controlling bacterial populations in soils; however, they may spread deeper, reaching the vadose zone of groundwater systems, especially where bacterial populations get to high densities.
Journal ArticleDOI
Protozoa in Planktonic Food Webs1,2
TL;DR: This paper adds new groups, the small (< 20 μm) ciliates and myxotrophic flagellates, to the planktonic food web.

Photosynthesis and Fish Production in the Sea
TL;DR: The two sets of variables primary production and the associated food chain dynamics may act additively to produce differences in fish production which are far more pronounced and dramatic than the observed variability of the individual causative factors.

The Measurement of Dissolved Organic and Particulate Carbon in SEAWATER1
David W. Menzel,Ralph F. Vaccaro +1 more
TL;DR: In this paper, a method for the rapid determination of dissolved organic carbon in seawater in concentrations between 0.1 and 20 mg/liter was described, which was carried out in sealed glass ampoules using K 2 S 2 O 8 as an oxidizing agent after the sample has been freed of inorganic carbon.
Journal ArticleDOI
The measurement of adenosine triphosphate in the ocean and its ecological significance1
TL;DR: The ATP levels found at various depths in the ocean indicate bacterial populations between 50−2,000 times those found by plating techniques, and the biomass of living material in the water has been estimated using the ATP content of laboratory cultured microorganisms as indicators of endogenous ATP levels.
