Effects of ocean acidification on copepods

Aquatic Toxicology, 2018
Ocean acidification (OA) leads to significant changes in seawater carbon chemistry, broadly affects marine organisms, and considered as a global threat to the fitness of marine ecosystems. Due to the crucial role of copepods in marine food webs of transferring energy from primary producers to higher trophic levels, numerous studies have been conducted ...

Photosynthesis in Copepods

Science, 1981
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 ...

Predation of calanoid copepods on their own and other copepods’ offspring

Marine Biology, 2014
Predation of eggs and nauplii by adult copepods is often used to explain unexpected death rates in population dynamics studies, but the phenomenon has been rarely investigated or quantified. Therefore, we studied the predatory feeding of adult females (Acartia clausi, Centropages hamatus, Centropages typicus, and Temora longicornis) on their own and ...

Photoperiodism in Copepods

2009
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.

Copepods and DMSP

1996
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 ...

Preparation of Copepods for Histopathological Examinations

Transactions of the American Microscopical Society, 1976
Few reports have been published on the preparation of copepods for microscopic study using standard histopathological techniques. Howes et al. (1972) used electron microscopy techniques for their histological studies. However, these techniques are too time consuming for laboratory and field studies involving large numbers of animals.
