The genus Artemia consists of several bisexual and parthenogenetic sibling species. One of them, A. franciscana, originally restricted to the New World, becomes invasive when introduced into ecosystems out of its natural range of distribution. Invasiveness is anthropically favored by the use of cryptobiotic eggs in the aquaculture and pet trade. The mechanisms of out-competition of the autochth...

surface topography and ultrastructure of dried cysts of artemia parthenogenetica (vedaranyam population) and bisexual artemia sp. (kelambakkam population) were studied electron microscopically in order to identify the bisexual strain, inhabiting covelong salterns, kelambakkam, south india. the scope of this study is to provide substantial information for further characterization of these artemi...

Abstract Brine shrimps ( Artemia ) have undergone geographic range and demographic expansions as a result of their interaction with humans since the beginning salt harvesting. This has favoured expansion some species but compromising survival others. Mediterranean native populations salina from coastal salterns lagoons are facing presence introduced invasive American monica (= A . franciscana )...

In the previously published mitochondrial genome sequence of Artemia urmiana (NC_021382 [JQ975176]), taxonomic status examined had not been determined, due to parthenogenetic populations coexisting with A. in Urmia Lake. Additionally, NC_021382 [JQ975176] has obtained pooled cysts (0.25 g consists 20,000–25,000 cysts), a single specimen. With regard Lake, and intra- inter-specific variations sa...

مایکوسپرین ها، متابولیت های جذب کننده تابش فرابنفش هستند که از طریق مسیر سنتز اسید های آمینه آروماتیک (shikimate pathway) تولید می شوند. در مطالعه حاضر به بررسی تاثیر نوع غذا بر میزان تجمع این ترکیبات در آرتمیا اورمیانا (artemia urmiana) و آرتمیای بکرزا (parthenogenetic artemia) پرداخته شد. سیست های هر دو جمعیت آرتمیا تحت شرایط استاندارد تخم گشایی شدند. لارو ها (ناپلیوس اینستار i) بلافاصله بعد ...

S EXUAL mosaics have been reported in three genera of Crustacea. A bilateral mosaic of Carcinus was found to have a testis on one side and a mixed gonad on the other (VEILLET 1945). Gynandromorphs with a testis and ovary have been reported in Homarus (see review by CHACE and MOORE 1959) and in the cladoceran, Simocephalus (BANTA, WOOD, BROWN and INGLE 1939). No intersex or mosaic of Artemia has...
