| Abstract | ||
| Up to date, the true phylogenetic relationships among the Artemia species are under debate. In this study, some morphometric and molecular (Inter-simple sequence repeats, ISSR) variations were analyzed to evaluate the biodiversity among some Egyptian Artemia species comparatively with other brine shrimps (A. parthenogenetica, A. salina and A. franciscana). The highest and lowest Wilks' lambda values were calculated for the Length of furca and the abdominal length. The cluster analysis based on the Artemia morphological variations was an agreement with the re-constructed dendrogram based on ISSR markers. The ISSR variations were comparatively analyzed with the Artemia species Cytochrome oxidase subunit I gene (COI) sequence variations. Based on the COI consensus sequences, the distance value between A. salina and A. parthenogenetica was higher than the distance value between A. salina and A. franciscana. The ISSR could be an effective method in Artemia molecular characterization and evolutionary studies. The results could be helpful in the conservation of the evaluated Artemia species. The combination of more informative molecular markers with the selected morphometric characters should be carried out to understand the true evolutionary variations in the Artemia resources | ||
