Organic Particles and Bacteria in the Ocean, is only recently, however, that any attempt has been made to partition nutrient regeneration between the various trophic levels. The purpose of this review is to examine the suitability of naturally occurring organic particles as substrates for bacterial growth and as sites for nutrient regeneratio

A Review of Measurements of Respiration Rates of Marine Plankton Populations,emann Nielsen of the .C-technique for measuring planktonic photosynthesis has enabled this particular process to be extensively and easily studied. As a consequence there is now a considerable body of data available of measurements of plankton photosynthesis. This contrasts with respiration for whic

The Use of Tracers and Water Masses to Estimate Rates of Respiration, That is, one obtains some measure of the “age” or velocity of a given parcel of water, and combining this with an observed deficit or gradient in dissolved oxygen concentration, one obtains an apparent oxygen utilization rate. The advantage of such an approach is that it represents a true .. measur

Protozoan Bacterivory in Pelagic Marine Waters,xcellently reviewed by Fenchel and Harrison (1976) and Fenchel and Jørgensen (1977) and demonstrated in a series of experiments by Fenchel (1977). In reviewing the role of protozoa in nutrient cycling and energy flow, Stout (1980) correctly states that there is little information on the nutrients an

Microbial Processes in the Sea: Diversity in Nature and Science,laced in marine studies by ones developed by ecologists. The recent results have brought the realization that microbial activities in the ocean biome are greater quantitatively and more varied than marine ecologists had realized.

Substrate Capture by Marine Heterotrophic Bacteria in Low Nutrient Waters, huge. The reservoir of DOC and POC in the ocean is placed at 655 × 10. tons and 14 × 10. tons respectively, assuming the values of 0.5 mg C·liter. and 10 µg C·liter. respectively (Menzel 1974). The turnover time is 3, 300 years (Menzel 1974).

Diel and Seasonal Variation in Growth Rates of Pelagic Bacteria,l volumes and of frequency of dividing cells (Krambeck et al. 1981), however, indicate short term variability. Diel patterns in bacterial heterotrophic activity in the pelagic ecosystem, recorded using tracer techniques (Ammerman and Azam 1981; Spencer 1979), also seem to agree well with the variati
