The essential amino acid composition (EAA) of females and eggs of Euterpina acutifrons and their food was analyzed on copepods fed with different microalgae and collected from the field. There were not significant differences in the EAA of females, but the EAA of eggs varied according to food source. As predicted by homeostasis theory, a higher reproductive success was observed as the EAA of females and food became more similar. This chemical homeostasis explains the selective retention of… 

Amino Acid Composition of Green Microalgae and Diatoms, Cyanobacteria, and Zooplankton (Review)

It is concluded that the AA composition of major groups of plankton is heterogeneous and the role of AAs as a limiting factor for the development of herbivorous zooplankton is discussed.

Amino acid composition of epilithic biofilm and benthic animals in a large Siberian river

There was an imbalance in the percentage of the essential amino acids between benthic animals and their food (the epilithic biofilm), which suggests that benthics animals may be limited by food quality.

Comparisons among the amino acid composition of females, eggs and food to determine the relative importance of food quantity and food quality to copepod reproduction

Food quality mainly limited copepod reproduction in spring and early summer, whereas food quantity limited reproduction at the end of autumn and early winter, whereas in summer and early autumn the reproductive success of copepods was higher.

Correction: Dietary Essential Amino Acids Affect the Reproduction of the Keystone Herbivore Daphnia pulex

The data suggests that the algal amino acid composition cannot explain the observed effects of algal diet on the reproductive strategy of Daphnia and suggests that also Chlamydomonas as a food organism leads to an increased resting egg production of daphnids compared to a high quality cryptophyte diet.

Biochemical and technical observations supporting the use of copepods as live feed organisms in marine larviculture

In this study, the sizes, weight and biochemical contents of two copepods and one rotifer species raised on similar algal food conditions were compared and the FAA pattern of the preys tended to be species-speci¢c and its implications from an aquaculture point of view is discussed.

Biochemical nutrient requirements of the rotifer Brachionus calyciflorus: co‐limitation by sterols and amino acids

The results add to growing evidence that consumers frequently face multiple nutrient limitations and suggest that the concept of co-limitation has to be considered in studies assessing nutrient-limited growth responses of consumers.

Biochemical Composition of Protists: Dependency on Diet and Trophic Mode and Consequences for their Nutritional Quality

It is concluded that dietary fatty acid and amino acid composition influences the composition of the four freshwater protist species to a minor extent, and that species-specific differences in fatty acids and amino acids metabolism are more important determinants of the biochemical composition in the analysed heterotrophic protists.

Single dietary amino acids control resting egg production and affect population growth of a key freshwater herbivore

It is suggested that the availability of single dietary amino acids potentially affects the seasonal dynamics and long-term persistence of Daphnia populations in the field, which may have consequences for the efficiency of carbon transfer and thus the trophic structure of freshwater food webs.

Effects of season and maternal food on Calanus finmarchicus reproduction, with emphasis on free amino acids

The data support the hypothesis that similarity in the free pool of EAA of diet and female promotes high fecundity and egg hatching success in C. finmarchicus.

Effects of food quality on the reproductive success of Acartia tonsa and Acartia hudsonica: laboratory observations

Hatching success of eggs decreased with the age of the algal culture, but no correlation was found with the meansured chemical components of the food.

Reproduction and growth of Euterpina acutifrons (Copepoda: Harpacticoida) under experimental conditions

The influence of food concentrations on adult life-span and reproductive activity of E. acutifrons was analyzed and a good correlation was found between concentration of algal suspension and egg production.

The egg production of a marine planktonic copepod in relation to its food supply: Laboratory studies1

The results, together with the ratio of C:N in particulate matter in the sea off southern California, suggest that nitrogen potentially limits egg production by adult female Paracalanus and that ingested carbon is used inefficiently.

Food selection by copepods: discrimination on the basis of food quality

Consideration of cell carbon, nitrogen, and protein composition suggests that the copepods are maximizing nitrogenous ingestion (total protein and/or nitrogen).

Trade-off between offspring number and offspring size in the marine copepod Euterpina acutifrons at different food concentrations

The reproductive strategy of directing more energy toward offspring size rather than offspring number, at low food concentrations, clearly increases reproductive success.

Digestion and alteration of the biochemical constituents of a diatom (Thalassiosira weisflogii) ingested by an herbivorous zooplankton (Calanus pacificus)

A laboratory experiment was conducted in which 14C-labeled diatoms (Thalassisora weissflogii) were fed to an herbivorous copepod zooplankton (Calanus pacificus). Digestion efficiencies, as defined by

Copepod recruitment and food composition: do diatoms affect hatching success?

Both egg production and hatching were found to be affected by the nutritional quality of the food and female fertility, and Hatching was also highly dependent on female fertility.

Copepod egg production in Long Island Sound, USA, as a function of the chemical composition of seston

The results from 4 path analysis models showed that chl and ciliates exert an important control on natural egg production rates, through their chemical composition, despite the fact that linear correlations between phytoplankton and clliates and E, were not significant.
