Abstract |
A detailed morphological and allometrical study was performed with adult males and females of eleven bisexual populations of brine shrimp Artemia . Multivariate procedures, discriminant and cluster analysis, allowed to separate and group together populations which exhibit great genetic similarities. The eleven populations studied form four distinct groups: the A. franciscana group, the A. tunisiana group, the A. urminiana group and a broader group which includes Eastern Old World populations. Scanning electron microscopy revealed differences in the male genital organs of an A. tunisiana population by lacking a medial protuberance in the base of the penes while the pattern of the ectodermal ridges of the brood pouch of A. urmiana markedly differed from the other populations studied. |
