The water quality in a Southern Chile river was characterized using the Biotic Index in a spatio-seasonal context, to analyze the composition and distribution of benthic macroinvertebrates and their correlation with 14 physico-chemical parameters. Sampling was done over a year at 5 sampling stati...

The community of crustacean zooplankton in lakes can show temporal vertical variations in composition and abundance due to the influence of exposure to natural ultraviolet radiation. The aim of the present study was to analyse the zooplankton composition both at the surface and in the water colum...

A coastal-lake wetland is a type of inland water ecosystem that does not occur very frequently in Chile, of which lakes Budi, Huillinco and Cucao are examples. Textural differences were found in the various constituent parts of the coastal lake sediments. Gravel was the smallest fraction and show...

We describe the benthic macroinvertebrate associations Budi coastal lagoon southern Chile, salt nature. They relate the abundance and biomass species with organic matter levels and types of sediment, 9 stations were chosen for sampling. The muddy bottom is the substrate dominates more than gravel...

Over the past few decades, land-use changes through conversion of global forest cover to exotic plantations is contributing to both habitat and biodiversity loss and species extinctions. To better understand human influences on ecosystem, we use diet composition from introduced Rainbow Trout Onco...

The zooplankton assemblages in deep, mostly oligotrophic northern Patagonian lakes are characterized by low species numbers and a marked dominance of calanoid copepods. In the present study, data collected in field work on six water bodies located in Alerce Andino National Park (41 degrees S) wer...

Andean grasslands of the La Araucania Region are used every year by Pehuenches communities as forage resources for their livestock. Grazing is one of the most important disturbances which affect natural meadows and can produce changes at community level in the species richness and plant compositi...

The swamp forests of south-central Chile have been greatly altered by the fragmentation of the landscape, which is mainly derived from anthropogenic activities. Despite their high ecological and conservation value for the biodiversity, these ecosystems have been scarcely studied. The main goal of...

This paper describes the geomorphology of the coast of La Araucania, using methods proposed by Tricart (1985) End licher (1985) and the classification methods of Francke et al. (2004). Based on morphological, morphometric, morphogenetic and land use patterns, the most representative geomorphic un...

The concentrations of cadmium, lead, manganese and zinc were determined in the fish species Micropogonias manni captured in Budi Lake, Araucania Region (Chile). The measurements were made by atomic absorption spectroscopy, and the analysis considered the sex, weight and size of the species; the r...
