Importance of environmental factors for the richness and distribution of benthic macroinvertebrates in tropical headwater streams

Creator:: Ferreira, Wander R., Ligeiro, Raphael, Macedo, Diego R., Hughes, Robert M., Kaufmann, Philip R., Oliveira, Leando G., and Callisto, Marcos
Abstract:: An understanding of the interactions among local environmental factors (e.g., physical habitat and water quality) and aquatic assemblages is essential to conserve biodiversity in tropical and subtropical headwater streams. We evaluated the relative importance of multiple physical and chemical habitat variables that influence the richness of Ephemeroptera, Plecoptera, and Trichoptera...

Is the diet of a typical shredder related to the physical habitat of headwater streams in the Brazilian Cerrado?

Creator:: Ferreira, Wander R., Ligeiro, Raphael, Macedo, Diego R., Hughes, Robert M., Kaufmann, Philip R., Oliveira, Leandro G., and Callisto, Marcos
Abstract:: Macroinvertebrates are important for processing leaf detritus in temperate streams, but studies about their role in tropical streams often present conflicting results. Via digestive tract analyses, we assessed the diets of Phylloicus sp. larvae (Trichoptera: Calamoceratidae), collected from streams of two southeastern Brazil river basins (Araguari, Sao Francisco). We classified...

Abstract:: Assessing the ecological impacts of anthropogenic pressures is a key task in environmental management. Multimetric indices (MMIs), based on aquatic assemblage responses to anthropogenic pressures, have been used increasingly throughout the world. The MMI approach is a low-cost, rapid field method that produces an aquatic condition index that responds precisely...

Defining quantitative stream disturbance gradients and the additive role of habitat variation to explain macroinvertebrate taxa richness

Creator:: Ligeiro, Raphael, Hughes, Robert M., Kaufmann, Philip R., Macedo, Diego R., Firmiano, Kele R., Ferreira, Wander R., Oliveira, Deborah, Melo, Adriano S., and Callisto, Marcos
Abstract:: Most studies dealing with the use of ecological indicators and other applied ecological research rely on some definition or concept of what constitutes least-, intermediate- and most-disturbed condition. Currently, most rigorous methodologies designed to define those conditions are suited to large spatial extents (nations, ecoregions) and many sites (hundreds to...

The relative influence of catchment and site variables on fish and macroinvertebrate richness in cerrado biome streams

Abstract:: Landscape and site-scale data analyses aid the interpretation of biological data and thereby help us develop more cost-effective natural resource management strategies. Our study focused on environmental influences on stream assemblages and we evaluated how three classes of environmental variables (geophysical landscape, land use and cover, and site habitat), influence...

Abstract:: Reservoirs can have both positive and negative effects on differing fish species depending on the species concerned and reservoir morphology, flow regime, and basin location. We assessed the influence of limnological zones on the ichthyofauna of three large Neotropical reservoirs in two different river basins. We sampled fish through use...
