Sphagnum peatlands are threatened at a global scale, not only by peat extraction, but also by Sphagnum harvesting. In Chile, dry Sphagnum moss is mainly exported for use as substrate for horticulture and orchids. Although the use of Sphagnum within Chile is limited, there are no data about its pr...

Las turberas de Sphagnum están amenazadas a escala global, no solo por la extracción de turba, sino también por la cosecha de Sphagnum. En Chile, el musgo seco es importado principalemente para su uso como sustrato para la horticultura y cultivo de orquídeas. Aunque el uso del musgo en Chile es l...

The secretion of enzymes involved in biocontrol from the wild T. harzianum strains Th11 and Th12 and the mutants Th11A80.1, Th11C40.1 and Th12A10.1 was studied after their cultivation in the presence of R. solani cell walls as the sole carbon source. The results showed that endoprotease activity ...

La secreción de enzimas involucradas en biocontrol por las cepas silvestres de T. harzianum Th11 y Th12, y de sus mutantes Th11A80.1, Th11C40.1 y Th12A10.1, se analizó luego de cultivarlas en medio líquido usando paredes celulares de R. solani como única fuente de carbono. Los resultados mostraro...

Many angiosperms are exclusively dependent on pollinators for its reproduction (Matallana et al.2010; Arroyo et al. 2006). However, pollinators sometimes could be erratic and variable in relation to the ecological context (e.g., plant community composition), especially in alpine zones where it is...

En Chile, la política habitacional y urbana se aparta de las aspiraciones de las familias pobres. Este artículo analiza las acciones que los pobladores emprenden para crear y consolidar su hábitat, especialmente para acceder a suelo y vivienda, y relaciona estas acciones con la política pública. ...

In Chile, housing and urban policies are out of touch with the aspirations of poor families. This paper analyzes the actions carried out by residents to create and consolidate their habitat, especially when it comes to gaining access to land and housing, and relates these actions to public polici...

Background: Antifreeze proteins (AFPs) production is a survival strategy of psychrophiles in ice. These proteins have potential in frozen food industry avoiding the damage in the structure of animal or vegetal foods. Moreover, there is not much information regarding the interaction of Antarctic b...

We present the first stellar density profile of the Milky Way bulge that reaches latitude b = 0 degrees. The profile was derived by counting red clump stars within the colour-magnitude diagram that was constructed using the new PSF-fitting photometry from VISTA Variables in the Via Lactea (VVV) s...
