Rodents have a high impact on human activities, producing economical losses and diseases. One of these diseases is Hantavirus syndrome, whose reservoir is Oligoryzomys longicaudatus. Raptors are the natural biological controllers of rodents, being, therefore, our efficient and effective allies. D...

Caesium-137 measurements have been used to document changes in the rate and extent of soil erosion associated with the shift from conventional tillage to a no-till system on a farm in south-central Chile. The study site is located in the Coastal Mountains of the 9th Region (38 degrees 37'S 73 deg...

Changes in land use which directly or indirectly affect freshwater fauna constitute one of the principal anthropic factors which have caused world biological diversity to disappear rapidly during recent decades. This fauna includes aquatic benthic macroinvertebrates, organisms presenting temporal...

Background: Allergic rhinoconjunctivitis (ARC) has a prevalence of 30% in industrialized countries. For an accurate diagnosis and treatment, it is crucial to identify the causative aeroallergen. Aim: To evaluate aeroallergen sensitization in adults with ARC in the city of Temuco, Chile. Patients ...

Chile is free of B. melitensis since 1975, but B. abortus is still present and also can infect goats. In Argentina there are both organisms. This situation is a potential risk for chilean herds that use common summer grazing areas near the border with Argentina. The aim of this study was to deter...

The timber exploitation in the department of Imperial between 1867 and 1920 is analysed for the first time, taking into account the causes of this exploitation, the form in which the wood was harvested, and the environmental consequences of this activity. Primary sources (records and writings fro...
