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, ...

The fish fauna of a subtropical mountain stream in Argentina was surveyed for the first time. The abundance and occurrence of species were explored considering variation in hydrology, seasonality and the abiotic environment. ...

We evaluated changes in the succession process in benthic algal communities of an afforested stream by comparing them with those in a grassland stream through analysis of temporal changes in composition, structure and ...
