The aim of this study was to understand how a stream ecosystem that flows from its fountainhead to its mouth inside a city, changes from a water resource to a point pollution source. A multidisciplinary descriptive approach was adopted, including the short-term temporal and spatial determination of physical, chemical, biological and ecotoxicological(More)
Interstitial annelids in the family Saccocirridae live in the extremely turbulent and dynamic swash zone of exposed sandy beaches. We examine herein the relationship between distribution patterns of Saccocirrus pussicus du Bois-Reymond Marcus 1948 and morphodynamics, hydrodynamic zones, and environmental variables at beaches sampled along the Brazilian(More)
There is scientific evidence that beach sands are a significant contributor to the pathogen load to which visitors are exposed. To develop beach quality guidelines all beach zones must be included in microbiological evaluations, but monitoring methods for beach sand quality are relatively longstanding, expensive, laborious and require moderate laboratory(More)
Forest management in a biological reserve is removing eucalyptus. Siparuna guianensis (early secondary), Xylopia sericea and Byrsonima sericea (pioneers) are the three most abundant native species in the eucalyptus understory. Chlorophyll a fluorescence and photosynthetic pigments were analyzed every 2 weeks for 120 days after clearcutting to answer: (i)(More)
Extreme physical conditions usually limit the meiofauna occurrence and distribution in highly hydrodynamic environments such as reflective beaches. Despite sediment grains of the upper layers being constantly resuspended and deposited, the high energy of the swash zone besides depositing coarse sediments allows an ample vertical distribution of meiofaunal(More)
River or alluvial sand mining is causing a variety of environmental problems in the Itajaí-açú river basin in Santa Catarina State (south of Brazil). When this type of commercial activity degrades areas around rivers, environmental restoration programs need to be executed. In this context, the aim of this study was to assess the evolution of a restored(More)
