Lotic ecosystems can be studied on several spatial scales, and usually show high
heterogeneity at all of them in terms of biological and environmental characteristics …

The water quality of an urban stream in southeast Brazil was evaluated using species of
Tubificidae (Annelida: Oligochaeta) as biological indicators. From May 2005 to April 2006, a …

Large scale palm oil plantations for the production of vegetable oil are among the most
harmful agricultural activities to biodiversity, especially given their rapid expansion …

Since the relative role of local and regional abiotic factors on the Odonata diversity in
rainforest streams is still poorly understood, we evaluated the effects of these factors on …

Anthropic activities are one of the main drivers of change in the environmental
characteristics of streams and the diversity of aquatic macroinvertebrates. We evaluated the …

This study investigated the effects of activities carried out by traditional populations on
aquatic ecosystems using the assemblages of Ephemeroptera, Plecoptera, and Trichoptera …

Abstract The Atlantic Forest domain, one of the 25 world's hotspots for biodiversity, has
experienced dramatic changes in its landscape. While the loss of species diversity is well …

Assemblages of Ephemeroptera, Plecoptera and Trichoptera (EPT) of rocky substrates were
studied in two streams of the Intervales State Park. Monthly collections with a Surber …

Mesohabitat components such as substrate and surface flow types are intimately related to
benthic macroinvertebrate assemblages in streams. Visual assessments of the distribution of …

Biotic indices to monitor water quality are helpful tools for evaluating the health of rivers and
lakes. In Brazil water samples are mainly analyzed using physical and chemical attributes …
