Evolutionary Role

Contagious parthenogenesis – a process involving rare functional males produced by a parthenogenetic lineage, which mate with coexisting sexual females resulting in fertile parthenogenetic offspring – is one of the most striking mechanisms responsible for the generation of new parthenogenetic lineages. Populations of the parthenogenetic diploid brine shrimp Artemia produce fully functional males in low proportions. The evolutionary role of these so-called Artemia rare males is, however, unknown. Here we investigate whether new parthenogenetic clones could be obtained in the laboratory through contagious origin. We assessed the survival and sex ratio of the hybrid ovoviviparous offspring from previous crosses between rare males and females from all Asiatic sexual species, carried out cross-mating experiments between F1 hybrid individuals to assess their fertility, and estimated the viability and the reproductive mode of the resulting F2 offspring. Molecular analysis confirmed the parentage of hybrid parthenogenetic F2. Our study documents the first synthesis of parthenogenetic lineages through contagious parthenogenesis in Artemia. We discuss the possible genetic mechanisms responsible for parthenogenesis and the likelihood of contagious parthenogenesis in natural environments.

Light Intensities

We explored the behavioral response to horizontal gradients of light and heat of sympatric diploid and pentaploid Artemia parthenogenetica. When exposed to a uniformly illuminated thermal gradient, pentaploids had a mean distribution that was oriented toward temperatures 2.9 °C higher than that of diploid animals. In a light gradient, diploids were distributed at higher light intensities than pentaploids. When the distributions in an evenly illuminated thermal gradient were compared with those occurring when thermal and light gradients ran in opposite directions, it was found that diploids tended to occur at lower temperatures, whereas pentaploid distributions were not significantly different for the two conditions. Our findings suggest that pentaploids are not as strongly attracted to light as diploids, in either the presence or the absence of a thermal gradient. We predict that in the field, warmer areas of a pond may be exploited by pentaploids during the day and by diploids during the night.
