Artemia franciscana C. Drewes (updated, 2002) http://www.zool.iastate.edu/~c_drewes/ http://www.zool.iastate.edu/~c_drewes/Artemph.jpg Taxonomy Phylum: Arthropoda Subphylum): Crustacea Class: Branchiopoda (includes fairy shrimp, brine shrimp, daphnia, clam shrimp, tadpole shrimp) Order: Anostraca (brine shrimp and fairy shrimp) Genus and species: Artemia franciscana (= the North American versio...
This study reports on the induction of oxidative stress in aerobic cell systems by Aloe barbadensis Miller (Aloe vera) juice using the salt water crustacean Artemia franciscana as a model. A consistent pattern was observed in which Artemia franciscana nauplii responded to Aloe vera juice exposure with a decrease in the overall activity of redox related enzymes. Exposure of Artemia franciscana t...
Artemia brine shrimps inhabit hypersaline ecosystems all over the world except Antarctica. In South America two bisexual diploid species are encountered: Artemia franciscana Kellogg distributed along America and Artemia persimilis Piccinelli and Prosdocimi restricted to Argentina and a few Chilean localities. A. franciscana was recently cited for the first time in our country and our results su...
The meaning of alternative biotests is described and discussed. The paper also deals with the possible application of the developmental studies of the sea Artemia franciscana nauplinus. Five-day biotests including the validation criteria are described. The possibilities of the biotests are very wide. Additionally to the standard applications in ecotoxicology, there is a possibility of modelling...
Endemic Artemia franciscana populations can be found throughout the American continent and also as an introduced specie in several country all over the world, such as in the Mediterranean region where Artemia franciscana was identified as an invasive specie replacing native Artemia parthenogenetica and Artemia salina. In the present study, the characterization of the new invasive Artemia franci...
The lethal responses to cadmium of instar II nauplii from eight populations of Artemia belonging to the species Artemia franciscana, Artemia salina, Artemia persimilis, and Artemia parthenogenetica have been compared. Generalized linear models were used to fit mortality. The model indicates that there is a relationship between species, type of population, and mortality rate. The two populations...
A 3D conceptual framework of 'critical windows' was used to examine whether the morphometry of Artemia franciscana is altered by salinity exposure during certain key periods of development. Artemia franciscana were hatched at 20 ppt (designated control salinity) and were then exposed to 10, 30, 40 or 50 ppt either chronically (days 1-15) or only on days 1-6, 7-9, 10-12 or 13-15. On day 15, matu...
در این تحقیق، تنوع ژنتیکی جمعیت آرتمیا اورمیانا و آرتمیا فرانسیسکانا ی موجود در ایران با استفاده از 5 جفت آغازگر ریزماهواره ای (af-b105tail، af-a136، apdq03tail، apdq04tail و apdq05tail) ویژه ی آرتمیا فرانسیسکانا و آرتمیا پارتنوژنتیکا بررسی شد. از 50 سیست آرتمیا ی هر یک از این دو جمعیت به صورت انفرادی dna با روش گلوله ی داغ استخراج شد. با استفاده از آغازگر ها ی پنج گانه و از طریق واکنش زنجیره ا...
Sex allocation theory is often hailed as the most successful area of evolutionary theory due to its striking success as a predictor of empirical observations [1]. Most naturally occurring sex ratios can be explained by the principle of equal investment in the sexes [2-4] or by cases of "extraordinary" sex allocation [5]. Deviations from the expected sex ratio are often correlated with weak sele...
The brine shrimp Artemia, an excellent live food source in aquaculture, has been studied as a carrier to deliver selected chemotherapeutic agents to fish for prophylactic treatment of infectious diseases. To monitor the efficiency of incorporation of trimethoprim and sulfamethoxazole in Artemia franciscana, a sensitive and specific analytical method was developed. It is based on homogenization ...
