Molecular phylogenetics and asexuality in the brine shrimp Artemia
Molecular Phylogenetics and Evolution, 2006Explaining cases of long-term persistence of parthenogenesis has proven an arduous task for evolutionary biologists. Interpreting sexual-asexual interactions though has recently advanced owing to methodological design, increased taxon sampling and choice of model organisms.

The carotenoids of the brine shrimp, Artemia salina
Comparative Biochemistry and Physiology, 1965Abstract 1. 1. The carotenoid pigments of the Branchiopod crustacean, Artemia salina were studied. They consisted exclusively of the keto-carotenoids, canthaxanthin and echinenone, in a ratio of 19:1. 2. 2. These findings were discussed with relation to the carotenoid pigments in the other sub-classes of crustacea.

A Compact and Efficient Brine Shrimp Hatching Device
Recent Patents on Biotechnology, 2023Background: Artemia is considered an indispensable live food for rearing many fish and crustacean larvae and can be used in toxicity tests as a safe, practical, and economical method. It is straightforward to create and manipulate; however, many cysts do not hatch as expected. Methods: A new device was used to hatch Artemia salina.

Evolution of a polymeric globin in the brine shrimp Artemia
Nature, 1990Several invertebrate species possess haemoglobins in which each polypeptide contains multiple haem-binding domains, possibly reflecting the fusion of multiple monomeric globin transcriptional units at the gene level. We have now analysed the transcript of such a polymeric globin gene from the brine shrimp Artemia, which expresses three polymeric ...

The Costs of Reproduction in Brine Shrimp
Ecology, 1982Brine shrimp were subjected to one of four reproductive regimes: complete absence of mating, mating postponed for 20 d or 40 d past sexual maturity, or continuous breeding upon sexual maturity (controls). Each of the four reproductive regimes was further subdivided into low and high feeding groups (1:10 feeding ratio).

Reexamination of hemocytes in brine shrimp (Crustacea, Branchiopoda)
Journal of Morphology, 1999In 1941, a single type of hemocyte was described in the blood of the brine shrimp Artemia salina using light microscopy. This condition is unusual because most crustaceans examined using morphological, cytochemical, and functional methods have at least two types of hemoctyes. Upon examining A. franciscana, we found a single type of disk-shaped hemocyte,

Changes in transfer RNA in developing brine shrimp
Developmental Biology, 1970Summary Aminoacyl-tRNAs prepared with tRNA from two developmental stages of the brine shrimp, Artemia salina , were fractionated by reversed-phase column chromatography. Between the encysted gastrula stage and the nauplius larva stage, quantitative changes occur in the isoaccepting tRNAs for nine amino acids.

Molecular Aspects of Development in the Brine Shrimp Artemia
1984Publisher Summary The brine shrimp Artemia possesses an unusual reproductive cycle. This chapter discusses the molecular aspects of development in the brine shrimp Artemia . The molecular aspects of development examined in the chapter are (1) the amount and activity of polypeptide-chain-initiation-factors in embryos before and after the resumption
