Glaciers that directly feed high-altitude streams create unique environmental conditions that contribute substantially to regional-scale lotic habitat diversity and biodiversity, including intra-specific genetic diversity ...

Lotic ecosystems are highly affected by land use changes such as afforestation of natural areas for management or commercial purposes. The aim of this study was to analyze the effect of pine plantations on benthic invertebrate ...

The aim of this study was to verify structure patterns in fish assemblages in mountain streams of the Rio Tibagi basin through the characterization of spatial and temporal variations in the composition of fish species. ...

Small water bodies are critical for maintaining freshwater biodiversity, but are among the least investigated of aquatic environments. We examined physical and chemical variables at two reaches in Arroyo Tambillos, a small, ...
