The purpose of this study was to determine the temporal evolution of soil properties following the incorporation of biosolids in a degraded Inceptisol soil (Typic Endoaquepts). The study was conducted in the Araucan a Region of Chile, where two sampling zones were established: a control zone with...

The Chilean north Patagonian inland waters are characterized by their low mineral concentrations. In their original status, many of these ecosystems have native vegetation in their surrounding drainage basins, but in the last decades the native vegetation was replaced by agricultural, urban, and ...

Genypterus chilensis is a marine fish of high gastronomic demand, whose capture has declined in recent years due to overfishing. In the development of the farming technology, high mortalities were obtained during egg incubation. The objective of this study is to contribute to the knowledge of fec...

Nothofagus dombeyi grows in a wide variety of sites. The information about its productivity is still scarce, which makes it difficult for foresters and landowners to take decisions about the best practices to maintain and/or improve the goods and services derived from the forest. The aim of this ...

The genus Nothofagus is the main component of southern South American temperate forests. The 40 Nothofagus species, evergreen and deciduous, and some natural hybrids are spread among Central and Southern Chile, Argentina, New Zealand, Australia, New Guinea and New Caledonia. Nothofagus nervosa, N...

The suitability of Mazzaella laminarioides and Sarcothalia crispata as heavy metal biomonitors of Cd, Cu, Hg, Pb, and Zn was assessed by comparing bioaccumulation of these elements in different life stages and frond sizes in samples from three locations, San Vicente Bay (industrial area), Coliumo...

In different Mediterranean zones (MZ) of the world, extensive areas of native forests have been replaced by forest plantations composed of non-native species that exceeded 264 million ha globally in 2010. In Chile, 80% of these plantations are distributed in the same zone where forested wetlands ...

Decomposition of leaf litter is a fundamental process for the functioning of forested wetlands. The rapid increment of forest plantations has involved a greater contribution of leaf litter of exotic origin to these ecosystems. The decomposition rate between leaf litter of native and exotic origin...
