| Abstract The anostracan Artemia is one of the few organisms that can inhabit hypersaline lakes. In Argentina, this genus is represented by two species: the invasive A. franciscana Kellogg, 1906 and the autochthonous A. persimilis Piccinelli & Prosdocimi, 1968, the latter being the only one recorded in the province of La Pampa. Some of the biological aspects of A. persimilis are known based on laboratory studies, and data on its ecology in natural conditions are scarce. The aim of this work is to present information on the density, biomass, and population structure of A. persimilis in relation to environmental variables in Utracán, a hypersaline lake of the semiarid Central Pampa of Argentina. Water and zooplankton samples were taken monthly from May... |
