The management and use of native species under laboratory conditions is the main difficult for species proposal for its use in bioassays. The present study showed the results about management under controlled conditions of Paratanytarsus grimmii (Diptera: Chironomidae), that is a parthenogenetic ...

Studies in Salvelinus alpinus, Arctic charr, indicate that it has a low capacity to hyposmorregulatory or adaption to sea in winter periods in Arctic waters. The investigation finds to determinate the rank optimum of salinity to can cultivate this species at Chile. The weight adequate was determi...

The inland waters of Chile hold endemic species of crustaceans, and these habitats are threatened at present due to pollution as a result of human activities. Until now, the environmental studies performed have not considered native species for evaluating environmental risks. The aim of the prese...

In Chile there is an increased use of fungicides, especially in the central and southern parts of the country. The aim of this study was to test the sensitivity of two common zooplankton species, Daphnia pulex Leydig, 1860 and Tumeodiaptomus diabolicus (Brehm, 1935) to the fungicide carbendazim. ...

Easy, economic, precise species authentication is currently necessary in many areas of research and diagnosis in molecular biology applied to conservation studies of endangered species. Here, we present a new method for the identification of three fox species of the Lycalopex genus in Chile. We d...

The current trend in world aquaculture is towards the diversification of cultures, mainly native species. The red cusk eel Genypterus chilensis is a native Chilean species of high gastronomic demand and seasonal exploitation that is projected as a candidate for the development of farming technolo...

Nothofagus dombeyi is distributed on very diverse sites in the temperate forests of Chile and Argentina. In Chile, studies on its dynamics and productivity in forests, where it is the dominant species, have been carried out mainly in the foothills of the Andes, but the productivity and growth of ...

Based on recent advances in ecological network theory, we present an ad hoc conceptual framework and a methodological proposal for the evaluation of the ecological relevance of species within a community, oriented towards the Ecological Risk Assessment in Chilean aquatic systems. The procedure is...

Chile is the second largest producer of salmonids worldwide. The first step in the production of salmonids takes place in land-based aquacultures. However, the effects of the discharge from these aquacultures on stream dissolved organic matter (DOM) content, molecular composition and degradabilit...

A healthy body of freshwater can provide numerous benefits to the society, although currently, the degradation of such ecosystems has been increased due to the establishment of urban areas along its riverbanks. In this study we analyzed the spatial effect of these zones on the water quality, usin...
