Homeostasis in the essential amino acid composition of the marine copepod Euterpina acutifrons
@article{Guisande1999HomeostasisIT, title={Homeostasis in the essential amino acid composition of the marine copepod Euterpina acutifrons}, author={C{\'a}stor Guisande and Isabel Maneiro and Isabel Riveiro}, journal={Limnology and Oceanography}, year={1999}, volume={44} }
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…

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
- Environmental Science

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
- Biology
- 2000
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
- Environmental SciencePLoS ONE
- 2012
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.

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
- Environmental Science

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
- Environmental Science, Biology

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
- Environmental ScienceOecologia
- 2011
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.

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.
