Sampling Zooplankton: Correction
Science, 1995We have learned that there is an internal inconsistency in the zooplankton dataset used in our report "Climatic warming and the decline of zooplankton in the California Current" (3 Mar., p. 1324) ( 1 ). The data file we used, written from the archive maintained by the National Marine Fisheries Service, was found to ...

Four isomeric phytadienes have been isolated from mixed zooplankton of the Gulf of Maine. The chemical structures suggest that the mixture is derived by dehydration of phytol (presumably by acid catlysis), which is present in the diet of the zooplankton.

PHOSPHORUS IN MARINE ZOOPLANKTON
Water Research, 1973Abstract In the euphotic zone, phosphorus compounds dissolved in sea water are utilized by growing plants, many of which are subsequently eaten by herbivorous zooplankton and the dietary phosphorus invested partly in growth and egg production, partly released in insoluble form as faecal pellets and partly metabolized.

, 2000 Publisher Summary This chapter deals with improvements in mesozooplankton and macrozooplankton net sampling as well as other sampling techniques for describing the vertical and geographic distribution and biomass estimation of zooplankton. Traps to collect animals midwater or rising off the seafloor have been used less often to collect marine ...

The crustacean zooplankton of these large lochs is described from a series of vertical net hauls taken there during 1977–78. A total of 11 planktonic species of Crustacea was found — six of them common to all the lochs. There were sufficient differences in the occurrence of the other five species for it to be possible to identify the community of each ...

Abstract 1. 1. Arctic zooplankton were characterized by large amounts of depot lipids, either triglycerides or wax esters. 2. 2. The copepods ( Calanus hyperboreus, Calanus glacialis, Metridia longa, Paraeuchaeta barbata and Paraeuchaeta glacialis ) had a very high content of storage lipid (37–54 per cent of the dry weight) which was ...

This chapter reviews metazooplankton (>200 μm) respiration in aquatic systems. It discusses methodology, modifying agents (physical, chemical, and biological factors), definitions, and carbon equivalents. The major determinants of zooplankton respiration rate are argued to be body mass and temperature.
