Forest fires can produce significant impacts on the structure and functioning of natural ecosystems. In march 2015, a large-scale fort fire affected Araucaria ansucana-Nothofagus pumilio (araucaria-lenga) forts of high ecological value in National Reserve China Muerta (Chile, 38 degrees S), where...

Land-use change is a principal factor affecting riparian vegetation and river biodiversity. In Chile, land-use change has drastically intensified over the last decade, with native forests converted to exotic forest plantations and agricultural land. However, the effects thereof on aquatic ecosyst...

The crustacean zooplankton of Chilean inland waters are characterized by abundant calanoid copepods, mainly from the genus Boeckella. The present study aims to update the distribution of Boeckella gracilis in the inland waters of the Araucania region (38-39 degrees S) and to use null model analys...

The lakes studied (Tinquilco, Verde, Toro, Chico) are located in the Huerquehue National Park 39 degrees 08' S, 71 degrees 40' W), Chile. An inventory of the aquatic and riparian species was performed between December 2005 and March 2006. A null model analysis was done to determine the existence ...

Forested wetlands have hydroperiods that range from permanent to seasonal, constituting an important environmental factor that directly influences the biological activity. This study evaluated how hydrologic dynamics affect the structure of arboreal vegetation in the forested wetlands of southern...

The water bodies studied herein are located in the Huerquehue National Park, a mountain zone with Nothofagus alpina, N. pumilio, N. dombeyi, and Araucaria araucana forests, at 700-1500 m a.s.l. There are numerous oligotrophic lakes, with characteristics similar to the deep Araucanian lakes. Many ...

The coastal area of the Araucania Region stands out for the presence of wooded wetlands of Temu and Pitra (Blepharocalyo-Myrceugenietum exsuccae), from the association Blepharocalyo-Myrceugenietum exsuccae. These are nowadays affected by antropic activities. We evaluated the vascular flora, the d...
