Small mammals were studied in two southern Chilean temperate rainforests in the precordillean Andes during 2 low-rainfall years following the 1982 El Niño event. Forests had somewhat different levels of canopy, shrub, and herbaceous cover, and species richness of trees but most of the same plants...

Comparative demography and diversity of small mammals in precordilleran temperate rainforests of Southern Chile
In four samples of Artemia urmiana Günther, 1899 from Urmia Lake, Iran, the following parameters were compared: the diameter of the frontal knobs (right and left), and the respective ratios of that diameter with total body length and head width. The results do not denote significant differences i...
1. A fundamental goal of ecological network research is to understand how the complexity observed in nature can persist and how this affects ecosystem functioning. This is essential for us to be able to predict, and eventually mitigate, the consequences of increasing environmental perturbations s...
El presente artículo expone la tensión existente entre las diversas hipótesis explicativas del proceso de degradación
de los recursos naturales del territorio mapuche de Chile. Por una parte, desde el discurso oficial,
se plantea que esta degradación ambiental tiene su origen en la pobreza mapuch...
The recently developed dry method for the element determination of single freshwater microcrustacean specimens (Daphnia) using total reflection X-ray fluorescence (TXRF) spectrometry showed that inhomogeneities of the biological material on the glass carriers resulted in some cases in high backgr...
This study describes and analyses plant species diversity and identifies indicator species for nitrogen eutrophization in four coastal lagoons in the Araucanian Region, Chile. A total of 82 vascular macrophyte species were identified. Tromen lagoon has the highest species richness (45 taxa), foll...

Floristic comparison and trophic condition based on indicator species in coastal lagoons of the Araucanian Region, Chile
The study of food webs has been a central theme within ecology for decades, and their structure and dynamics have been used to assess a range of key properties of communities (e.g. complexity–stability relationships) and ecosystems (e.g. fluxes of energy and nutrients). However, many food web par...
Southern Patagonia is characterized by the presence of numerous shallow ponds with variable trophic and conductivity conditions, and a relatively high species richness of Crustacea. In the present study, published information and data collected in field work on shallow ponds in the Magellan regio...
El artículo reconstruye el debate en economía del desarrollo desde
la Segunda Guerra Mundial hasta hoy. Para ello, lo conecta con el valor del
progreso y de la producción de riqueza que ganaron lugar en siglos anteriores.
Se revisan los factores que permitieron la emergencia de un discurso

The article reconstructs the debate on economic development
since the Second World War until today. For that, connects to the value
of progress and wealth production that won place in previous centuries.
It reviews the factors that made the development discourse emerge, and
then, the various theo...
