The Chemistry of Artemia Habitats
Ecology, 1967Some populations of Artemia salina (L.) occur in high carbonate waters and potassium—rich media where Na/K ratios are low. These habitats previously have been thought to exclude this crustacean.

Abstract The eggs of the brine shrimp, Artemia salina, vary in colour from pale cream to dark brown. This variation is due to different amounts of haematin in the egg shells. Nauplii of Artemia are bright orange in colour owing to a carotenoid pigment, esterified astaxanthin. The same carotenoid is present in the eggs.

Abstract The brine shrimp, Artemia salina, gains or loses haemoglobin in its blood in response to a low or high dissolved oxygen content of the medium in which it lives. Females gain and lose the pigment more rapidly than males. In natural populations Artemia is redder in colour in proportion to the increasing salinity of the medium ...

Even a cursory glance at the previous chapters on diverse aspects of Artemia will have convinced you of the astonishing convergence of unique features in this one organism, Artemia. It will come as no surprise then, that Artemia is cherished as a study object and a commodity by physiologists, biologists, biochemicists, ecotoxicologists, geneticists ...

The individual Artemia populations vary considerably with respect to their tolerance for waters of different ionic compositions. Ecological isolation among these populations occurs because of an intolerance for each other's natural habitat due to differences in lakewater chemistry. The Artemia of the New World are bisexual and with the exception of one

GMP reductase in Artemia salina
Biochimica et Biophysica Acta (BBA) - Enzymology, 1974Abstract 1. 1. A GMP reductase (NADPH:GMP oxidoreductase (deaminating), EC 1.6.6.8) activity has been characterized, and partially purified, in Artemia salina extracts. The enzyme is specific for NADPH, has a k m of 0.01 mM for GMP, is maximally active at a pH value of approx. 8.5, requires thiol groups and is resistant to heating at

Diguanosinetetraphosphate guanylohydrolase in Artemia salina
Biochimica et Biophysica Acta (BBA) - Enzymology, 19741. The diguanosinetetraphosphate guanylohydrolase (EC 3.6.1.17) of Artemia salina has been found to be located in the cytosol while its substrate, diguanosine tetraphosphate, is in the sediment. 2. Two spectrophotometric methods have been developed to study this enzyme.

Adenosine deaminase isozymes in Artemia
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1984Three isozymes of adenosine deaminase, termed II, III and IV, have been detected in Artemia embryos. Their pI values, determined by chromatofocusing, were 4.9, 5.0 and 5.2, respectively. Upon development to larvae, a different isozyme (I) is induced, with a pI value of 4.2 as determined by isoelectric focusing.
