Inland water microcrustacean assemblages in an altitudinal gradient in Aysen region (46° S, Patagonia Chile)

Inland water microcrustacean assemblages in an altitudinal gradient in Aysen region (46° S, Patagonia Chile).

The Chilean Patagonia has numerous kinds of inland water ecosystems such as lakes, ponds, wetlands and rivers that have been poorly studied due to access difficulties. This study was carried out in Aysen region, in southern Chile, and it included different kinds of water bodies such as rivers, streams, ponds, lagoons and lakes distributed along an altitudinal gradient at 46° S. It was found a l...

Microcrustacean assemblages composition and environmental variables in lakes and ponds of the Andean region-South of Chile (37-39° S).

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° S, and shallow ponds at 51° S. The aim of the present study was analyse the zooplankton assemblages in different water bodies located in coastal zones, middle valleys and mo...

Directional changes in plant assemblages along an altitudinal gradient in northeast Brazil.

First observations of the aquatic invertebrate fauna in ephemeral Atacama River (22° S, Antofagasta Region, Chile)

The invertebrate communities of the northern Chilean rivers are characterised by their marked endemism andspecificity of their community structure in different basins. The river systems located in the Atacama Desert are endorheicand are affected by the rainy period of January-February commonly known as the “Bolivian winter“. The present study isthe first report on the observations of arthropods...

Spatiotemporal Influences of Climate on Altitudinal Treeline in Northern Patagonia

Tree radial growth and seedling establishment of Nothofagus pumilio at alpine treeline near 408 S latitude in Chile and Argentina show timeand site-dependent relationships to interannual-and decadal-scale climate variation. Six treelines were sampled at two spatial scales corresponding to regional and local climates. A shift in climate from cool–wet to warm–dry conditions facilitated comparison...
