Land-use effects on structural and functional composition of benthic and leaf-associated macroinvertebrates in four Andean streams
(2018)
The replacement of native forests by pastures takes place widely in the Andes. The effects of such land-use change on aquatic assemblages are poorly understood. We conducted a comparative analysis of the effects of forest ...
Benthic macroinvertebrate communities as indicators of river environment quality: an experience in Nicaragua
(Universidad de Costa Rica, 2002)
Benthic macroinvertebrate community patterns of Mediterranean forested wetlands and their relation to changes in the hydroperiod
(2014)
The macroinvertebrate community of Mediterranean forested wetlands (FW) in Southern Chile was studied to determine their temporary distribution patterns in relation to changes in the hydroperiod. A total of 540 samples ...
Rapid Bioassessment Protocols using benthic macroinvertebrates in Brazil: evaluation of taxonomic sufficiency
(University of Chicago Press, 2010)
Influence of hydraulic conditions over dunes on the distribution of the benthic macroinvertebrates in a large sand bed river
(American Geophysical Union, 2009-06)
This study aims to relate the flow structure over mobile dunes recorded on the channel bed of the Paraná River (Argentina) with the spatial distribution of the benthic macroinvertebrates. The following main conclusions ...
Metal leaching, acidity, and altitude confine benthic macroinvertebrate community composition in Andean streams
(Wiley, 2014)
Andean streams drain metal-rich bedrock and are subjected to an extreme altitude gradient, which may create highly selective conditions for life. The aim of the present study was to evaluate the combined effects of metals ...
Bioassessment using benthic macroinvertebrates of the water quality in the Tigreiro river, Jacuí Basin
(Brasil, 2013)
This study aimed to evaluate the water quality in the Tigreiro river, Jacuí river Basin, using different approaches. Benthic macroinvertebrates were sampled in July 2010 (winter) and February 2011 (summer) at five sites. ...
