Although the study of physicochemical characterization of Urmia Lake confirms the salinity of lake is changing but this study has focused on the pattern of Weight-Frequency Percentage (%WF) form 1852 to 2008. Reanalysis of last data showed %WF hasn’t had homogenous structure of Weight-Frequency P...

A sudy was made regarding the influence of salinity on the distribution of Egeria densa in the Valdivia river basin, Chile. Measurements were taken of the biomass of this species from locations of differing salinity within the range of its distribution in the Valdivia river. In the laboratory, th...

In Andes Mountains (14-27°S) and Patagonian plains (45-53°S) in Chile, there are numerous shallow saline and sub-saline lakes. These water bodies have important temporal and spatial variation of their salinity caused by mineral composition of their watershed or exposition to arid weather. In this...

The zooplankton in South American saline waters is mainly dominated by copepods at salinities lower than 90 g/l, whereas at salinities above 90 g/l Artemia sp. is totally dominant. The aim of the present study is to analyse the salinity range of halophilic copepods on the basis of a literature re...

Halotolerant Copepoda in South American inland saline waters
The calanoid copepod, Boeckella poopoensis Marsh, 1906 inhabits shallow saline ponds located in the Andes mountains in Argentina, Bolivia, Chile, and Peru, as well as in the plains of southern Argentina. The species is halophilic and can tolerate salinity levels of 1 to 90 ppt. This paper describ...

The chemical characteristics of the waters of Lake Budi (IX Region, Chile), in winter and summer were analysed in order to establish seasonal variations and determine their influence on the various phytoplankton components. On the basis of the results it was possible to indicate that the chemical...

Despite the importance of certain highly unsaturated fatty acids in osmotic regulation, few studies have been addressed to determine the essential fatty acid requirements for a given species cultured under different salinities. As Galaxias maculatus is a diadromic species, the present study aimed...
