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...

Se describen las diferentes asociaciones de macroinvertebrados bentónicos del lago costero Budi, Sur de Chile, de naturaleza salada. Se relacionan la abundancia y biomasa de especies con los niveles de materia orgánica y tipos de sedimento, para lo cual se eligieron 9 estaciones de muestreo. El f...

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

A study was made of the geographic distribution of swamp forest in the coastal territory of the Araucanía Region, Chile. An analysis of maps, aerial photographs, and satellite images was carried out, together with field work, to determine the location, degree of fragmentation, shape of fragments ...

The purpose of the present study was to investigate the seasonal relationship of macrobenthos richness and abundance with sediment characteristics (i.e. texture and organic material) for the coastal Budi Lagoon in southern Chile. Physicochemical measurements and macrobenthos samples were taken ov...

The aim of this study was to determine the feeding of Micropogonias furnieri (n= 256 of commercial size over 25 cm) during austral summer and winter 2004. During the summer period anchoveta Engraulis ringens was the main prey item in terms of percentage of frequency (%F), percentage of weight (%P...

Riparian vegetation comprises the ecotonal zone in the transition between a water body and the adjacent terrestrial environment and it plays an elemental role in the functioning of aquatic ecosystems. Coverage, structure, and composition of vegetation have a fundamental influence in controlling t...

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...

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...

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...
