The zooplankton assemblages in Chilean Patagonian lakes are characterised mainly by their low biodiversity and high predominance of calanoids copepods, a pattern that has been studied for large and deep lakes between 38-51 degrees S, and shallow ponds at 51 degrees S. The aim of the present study...

Vascular epiphytes represent 10% of the total vascular plants of the world. Nevertheless, because it is hard to reach them in the forest upper-canopy where they usually live, there are few studies (especially in Chile) about them. With the objective of identifying the vascular epiphytes growing o...

Programas de drenado ponen en serio peligro la permanencia de los humedales de Chile. Sin embargo, la flora y vegetación de estos ecosistemas han sido poco estudiadas. Este estudio clasifica los humedales de la costa de Toltén (IX Región, Chile), determinando su flora y vegetación. De acuerdo a l...

Drainage programs threaten many of Chile’s remaining wetlands, yet the flora and vegetation of these ecosystems have yet to be thoroughly documented. This study classifies and describes the flora and vegetation of the wetlands from the coast of Toltén, IX Region, Chile. According to the Ramsar cl...

The purpose of the present study was to investigate the seasonal relationship of macrobenthos richness and abundance with sediment characteristics (i.e. texture and organic material) for the coastal Budi Lagoon in southern Chile. Physicochemical measurements and macrobenthos samples were taken ov...
