Hyporheic invertebrate assemblages at reach scale in a Neotropical stream in Brazil.
In the Neotropical Region, information concerning hyporheic communities is virtually non-existent. We carried out a sampling survey in the hyporheic zone of the Tijuca River, in the Tijuca National Park, located in the urban area of the city of Rio de Janeiro. Biological samples from the hyporheic zone were collected in three different stream reaches, in June 2012. The main objectives were: 1) ...
متن کاملReach-scale manipulations show invertebrate grazers depress algal resources in streams
Experimental tools that enable manipulations of organisms at larger scales allow for comparisons of processes across multiple spatial scales and expand our ability to make predictions about ecological processes. We performed reachscale (i.e., 50 m2) manipulations of invertebrate communities in streams using a modified electroshocking technique to nondestructively remove invertebrates. In additi...
متن کاملRelationships of fish assemblages, instream physical habitat, and landscape characteristics of wadeable Iowa streams
Fish assemblages play a key role in stream ecosystems, and play a crucial role in the assessment of stream health. Physical habitat is a key component of stream ecosystems and plays a major role in determining biotic assemblages and stream integrity. There is increasing recognition of the role landscape factors play in determining biotic assemblages and stream integrity. Landscapes in Iowa and ...
متن کاملRelationships between water quality, habitat quality, and macroinvertebrate assemblages in Illinois streams.
The influence of specific stressors, such as nutrient enrichment and physical habitat degradation, on biotic integrity requires further attention in Midwestern streams. We sampled 53 streams throughout Illinois and examined relationships between macroinvertebrate community structure and numerous physicochemical parameters. Streams were clustered into four major groups based on taxa dissimilarit...
متن کاملHabitat use by the fish assemblages of two chalk streams
Patterns of habitat use by fish assemblages in two chalk streams in southern England were examined to identify species preferences with respect to major habitat gradients. Both study sites, although differing in some physical habitat characteristics, mainly channel width, water temperature and instream cover, could be arranged similarly along a continuum extending from erosional to depositional...
