Stream restoration efforts have increased, but the success rate is still rather low. The underlying reasons for these unsuccessful remain inconclusive and need urgent clarification. Therefore, aim of present study was to evaluate over 40 years stream fuel future perspectives. To this purpose we evaluated influence policy goals on efforts, biophysical objectives, measures applied including scale application monitoring efforts. Information obtained from five surveys that were held among...
Zooplankton assemblages (Copepoda and Cladocera) in a cascade of reservoirs large tropical river (SE Brazil)The construction for the production electricity is one major human interferences on rivers.This study analyzes structure microcrustacean 8 Paranapanema River.Samples were obtained during campaigns through vertical haul (from bottom to surface) with net 50 μm mesh size 19 stations distributed along watershed (ca.700 km).The 3 main tributaries sampled downstream, just like mouth zone ot...
The input of land use specific organic matter into lowland streams may impact sediment characteristics in terms food resources and habitat structure, resulting differences macroinvertebrate community composition. Therefore, we investigated to what extent structure communities. To this purpose linear multiple regression models were constructed, which biotic indices considered as response variables predictor variables, analysed 20 stream stretches running through five different types. Sediment...
The aim of the present study was to assess impact surrounding land use on structure and functioning lowland stream ecosystems. To this end, five different types were selected (forest, extensive grassland, intensive cropland wastewater treatment plant) each represented by four replicate streams, in which diel dissolved oxygen concentrations recorded, sediment water quality parameters measured macroinvertebrate community composition determined. Chironomus sp., Oligochaeta Gastropoda dominated...
Headwater streams harbor diverse macroinvertebrate communities and are hotspots for leaf litter breakdown. The process of breakdown mediated by macroinvertebrates forms an important link between terrestrial aquatic ecosystems. Yet, how the vegetation type in local riparian zone influences leaf-associated assemblages rates is still not resolved. We investigated fragmentation differ forested non-forested sites using experimental bags sixteen paired across eight headwater Switzerland. Our...
Abstract Up to now, most lowland stream restoration projects were unsuccessful in terms of ecological recovery. Aiming improve the success projects, a novel approach restore sandy‐bottom streams degraded by channel incision was launched, consisting addition sand combination with introduction coarse woody debris. Yet it remained unknown whether this measure is actually effective biodiversity improvements. The aim present study therefore evaluate if can hydromorphological complexity on short...
Water availability is influenced by climate conditions and physical characteristics such as topography, soil type, land use cover. The Atlantic Forest has a long deforestation history shows climatic environmental gradient that results in natural vegetation diversity driven mainly water local conditions. Therefore, ecoregions are expected to show variability of responses different hydrological effects caused land-use cover change. In this study, we compared the response among 11 areas native...
AIM: This study aimed to evaluate, comparatively, the influence of distinct environmental impacts in watershed on rivers Capivara, Lavapés, Araquá and Pardo transference effects downstream. METHODS: The limnological/water quality was carried out rainy (March/2007) dry (September/2007) seasons, considering 17 sampling stations. RESULTS: Variables such as channel width depth, water velocity temperature increased towards river's mouth; transparency, dissolved oxygen were higher upstream...
Some ecological attributes of planktonic copepods (composition, diversity, abundance and its relations with limnological variables) were compared in two deep dendritic reservoirs, 470km from each other, contrasting water retention time (WRT) ages construction. Data grouped different studies: samples collected monthly between March/00 to February/01, on the Salto Caxias Reservoir (Iguaçu River), tri-monthly January/00 October/01, Chavantes (Paranapanema River). Eight species Calanoida six...
