Abstract

Background: A preliminary biometric and ecologic database for the brine shrimp Artemia from Mexico and Chile is presented. The area abounds in small and seasonal ponds and large inland lakes, the latter mainly located in Mexico, although relatively large and isolated lakes are found in complex hydrological settings in pre-high plateau areas of Chile. This paper summarizes research efforts aimed at the localization, characterization, and evaluation of the aquaculture potential of Artemia populations in Mexico and Chile, which exhibit great habitat diversity (ponds, salterns, coastal lagoons, sea arms, coastal and inland lakes), contrasting weather conditions and different levels of isolation and human intervention.

The efficiency of CO2 sequestration via carbonate mineralization with simulated wastewaters of high salinity

“…Other massive supplies of Mg are the waters of salt lakes and saltpans, such as those occurring in Mexico, China and Turkey, having Mg concentrations in the range 10-50 g L −1 [37][38][39].…”

Changing Diversity in Changing Environment

“…Brine shrimp or Artemia (Crustacea, Anostraca) is a worldwide living species well-adapted to survive in very harsh hypersaline environments, such as salty lakes and lagoons (Clegg et al 2009), it typically shows enormous diversity at the genus level in terms of their ability to survive under different ionic compositions, climatic conditions, and altitudes. In this case study, Artemia species are served as ideal model organisms for biodiversity study in inland hypersaline lakes (Camargo et al 2005;Castro et al 2006;Hand SC 1982;Maniatsi et al 2009). In addition, the morphological variations displayed among Artemia populations also provide excellent materials for studying adaptive genetic polymorphisms at molecular levels.…”

Variation of the interphase heterochromatin in Artemia (Crustacea, Anostraca) of the Americas is related to changes in nuclear size and ionic composition of hipersaline habitats

“…Clarification of this paradox requires further analysis, but a preliminary hypothesis would be that particular environmental and water conditions may have effectively selected particular genomic and phenotypic features for this population. For instance, cyst size of this population, larger than that of other Chilean populations, appears to be associated with the particular ionic composition of the water in this site (Castro et al, 2006). In addition, analysis of the association between amount of interphase heterochromatin and the ionic concentration of the brines revealed a species-specific negative association with the sulphate and calcium ions, only in the case of A. franciscana.…”
