CEPEDA-PIZARRO, Jorge  y  ARMIJO LEON, Alfonso Antonio. Stream-flow and limnological dynamics of a surface body-water associated with a wet-pasture of the Andes of north-central Chile. Idesia [online]. 2014, vol.32, n.2, pp.11-19. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292014000200003.

By using an 18-years database, it was analyzed the behavior of a series of limnological parameters of a surface water body found in a wet-pasture located in the high mountain area of a river basin of north-central Chile. It is documented its stream-flow dynamics and the temporal variation of diverse physical and hydrochemical parameters. The system is characterized by a high temporal variability (both annually and monthly) of the parameters studied. This variability prevented to observe temporal patterns. Unlike the highest stream flow, the lowest flow showed a clear correspondence with the observed precipitation. The hydrochemical characteristics of the water body are consistent with the geological substrate of the study area.

Palabras clave : Andean limnology; desert Andes; alpine ecosystems; high-land wet-pastures; Andean streams.
