Zooplankton grazers consume appreciable amounts of algae that are not digested. Indigestibility has been considered of adaptive value to the algae and an unqualified disadvantage to the grazer. In Cartesian diver experiments, freshly killed copepods ( Acanthocyclops vernalis ) produced significant amounts of oxygen ...

At present there are approximately 11 500 known species of copepods. The number of species described during the past 27 years is nearly two-thirds of all those described in the previous 100 years. Approximately one-third of marine copepod species are parasites or associates, nearly equally divided between those on fishes and those on invertebrates ...

Molecular Characterization of Copepod Photoreception
The Biological Bulletin, 2017Copepod crustaceans are an abundant and ecologically significant group whose basic biology is guided by numerous visually guided behaviors. These behaviors are driven by copepod eyes, including naupliar eyes and Gicklhorn's organs, which vary widely in structure and function among species.

Two pelagic copepods, Calanus helgolandicus and Gaussia princeps , contained wax esters with 28 to 44 carbon atoms as major lipid constituents. In laboratory cultures of the former species, changes in nutrition (amount or species of diatoms fed) affected both the amount of total lipid and the

The fate of DMSP produced by phytoplankton cultures incubated with and without copepods of the species Eurytemora affinis was monitored to investigate the influence of zooplankton grazing activity on the release of dissolved DMSP and DMS. Processes related to the flux of DMSP through (sloppy) feeding, gut passage, fecal pellet formation and fecal ...

AbstractThis chapter summarizes studies of photoperiodism in copepods and suggests directions for additional research. There is ample evidence that several copepod functions manifest a pattern of rhythmicity that is synchronized to the cycle of day and night.
