Covariation of taxonomic and functional facets of β-diversity in Chilean freshwater fish assemblages: Implications for current and future processes of biotic homogenization

Sergio A. Castro, Pablo Rojas, Irma Vila, Fabián M. Jaksić

The biodiversity of assemblages that experience the introduction and extinction of species may lead to responses in two important facets: The taxonomic and functional diversity. The way in which these facets are associated may reveal important implications and consequences for the conservation …

Bacterioplankton Zonation Does Exist in High Elevation, Polymictic Lakes

Pablo Aguilar, Irma Vila, Rubén Sommaruga

The assessment of distribution patterns or zonation of planktonic microbes along the water column is a crucial step to interpret their function in the ecosystem. In lakes without seasonal thermal stratification or polymictic systems such as high elevation tropical lakes, planktonic bacterial …

Exotic species elicit decoupled responses in functional diversity components of freshwater fish assemblages in Chile

Pablo Rojas, Sergio A. Castro, Irma Vila, Fabián M. Jaksić

In the freshwater basins of central Chile, 28 exotic species have been introduced, which have contributed to increase taxonomic diversity. Nevertheless, how these species have modified the components of functional diversity in these assemblages, a key aspect in learning about their present …
