The level of human impact on the wetlands of the Lago Budi Basin was established, as a function of the degree of alteration to the basin and the degree of alteration to the wetlands. The former was evaluated on the basis of a spatial analysis of the fragility and stability of the hydrographical b...

Se determinó el nivel de antropización de los humedales de la cuenca del Budi, en función del grado de alteración de cuencas y el grado de alteración de humedales. El primero, evaluado a partir del análisis espacial de la fragilidad y estabilidad de la hoya hidrográfica. El segundo, a través de u...

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...

This study describes and analyses plant species diversity and identifies indicator species for nitrogen eutrophization in four coastal lagoons in the Araucanian Region, Chile. A total of 82 vascular macrophyte species were identified. Tromen lagoon has the highest species richness (45 taxa), foll...
