摘要: The genetic structure of the brine shrimp Artemia franciscana, an extremophile halophilic microcrustacean, from Great Salt Lake (USA), was investigated by analysis nucleotide sequences mitochondrial cytochrome c oxidase subunit I (COI), genomic fingerprinting ISSR-PCR (inter-simple sequence repeats polymerase chain reaction) and biometry. Samples six different geographical localities revealed ten distinct haplotypes with a mean high level haplotype diversity (HD = 0.6). Phylogenetic analyses supported null hypothesis, that shrimps this lake form panmictic gene pool low differentiation index (F ST = 0.05) rate flow (Nm = 2.8) between areas. Moreover, morphological parameters no population among all examined populations. Neutrality tests mismatch distribution A. franciscana has undergone recent expansion. In spite hypersaline conditions in Northern (Gunnison Bay) regions Lake, structures areas are not linked to ecological or limnological conditions. Therefore, should be considered as single management unit for conservation.
