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 ...

Important events of acute mortality without apparent pathological features are present in the salmon smolt production in the Araucania Region (southern Chile). The problem is focused on specimens of 0.2 to 1 g; causes points to pH acidification processes of running water and the presence of certa...

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...

Urbanisation is a dominant geographical trend and an important component of global change, with unprecedented implications for socio-economic, cultural and environmental characteristics. However, green areas, including original fragments, can help to conserve native diversity, improving the funct...
