Non-wadeable river bioassessment: spatial variation of benthic diatom assemblages in Pacific Northwest rivers, USA

Creator:: Pan, Yangdong, Hughes, Robert M., Herlihy, Alan T., and Kaufmann, Philip R.
Abstract:: Current bioassessment efforts are focused on small wadeable streams, at least partly because assessing ecological conditions in non-wadeable large rivers poses many additional challenges. In this study, we sampled 20 sites in each of seven large rivers in the Pacific Northwest, USA, to characterize variation of benthic diatom assemblages among...

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...

Ecological assessment of a southeastern Brazil reservoir

Creator:: Martins, Isabela, Sanches, Barbara, Kaufmann, Philip Robert, Hughes, Robert M., Santos, Gilmar Bastos, Molozzi, Joseline, and Callisto, Marcos
Abstract:: Reservoirs are artificial ecosystems with multiple functions having direct and indirect benefits to humans; however, they also cause ecological changes and influence the composition and structure of aquatic biota. Our objectives were to: (1) assess the environmental condition of Nova Ponte Reservoir, Minas Gerais state, southeastern Brazil; and (2) determine...

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...

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...
