Abstract
Mitotic and Meiotic Chromosomes of Artemia (Branchiopoda) from Populations of La Pampa Province, Argentina
Highlights
Three populations of Artemia from La Pampa Province, Argentina, were cytogenetically analyzed: Salinas Grandes de Hidalgo, Laguna Callaqueo, and Laguna Colorada Chica
The anostracan genus Artemia is taxonomically regarded as a group of several reproductively isolated sibling species, distributed worldwide, except for the Antarctic continent
In the New World, the genus is represented by three endemic bisexual species: A. franciscana Kellogg, 1906, A. persimilis Piccinelli and Prosdocimi, 1968, and A. monica Verrill, 1869
Summary
Three populations of Artemia from La Pampa Province, Argentina, were cytogenetically analyzed: Salinas Grandes de Hidalgo, Laguna Callaqueo, and Laguna Colorada Chica Both mitotic and male meiotic chromosomes were studied. Cytogenetic studies on Artemia have been hindered, due to its high chromosome number, small chromosome size, low mitotic index of nauplii, and frequent nonspecific chromosome associations (Barigozzi, 1974; Abatzopoulos et al, 1986). These factors turn the morphological characterization of chromosomes of Artemia into a very difficult task. Meiotic studies on the genus have been performed only on females (HalferCervini et al, 1968; Barigozzi, 1974)
