Taxonomy of benthic macroinvertebrates in Jajrud River for water quality assessment [PDF]
Environmental Resources Research, 2020 The invertebrates are one of the most important terrestrial fauna and freshwater taxa.Benthic macroinvertebrates include aquatic insects and spiders, mites, crustaceans, andspecies of mollusks and worms that are aquatic in their immature stages and ...

Biomonitoring of lake sediments using benthic macroinvertebrates [PDF]
TrAC Trends in Analytical Chemistry, 2012 The Water Framework Directive (2000/60/EC) is an innovative piece of legislation aimed at protecting the quality of all continental and coastal waters in Europe through an ecological evaluation of the ecosystems. Since it is widely acknowledged that the greater the ecological realism the greater the difficulty of its definition, we describe the ...

Changes in invertebrate assemblage composition in benthic and hyporheic zones during a severe supraseasonal drought [PDF]
, 2014 Droughts are unpredictable disturbances characterized in streams by declining flow, reduced habitat availability, and deteriorating abiotic conditions.

Benthic Macroinvertebrate Susceptibility to Trout Farm Effluents [PDF]
Water Environment Research, 2009 The direct effects of a Virginia trout farm on benthic macroinvertebrates were examined using multiple approaches. Static laboratory tests with the amphipod, Hyallela azteca, were conducted with exposures to water taken from a spring and from effluent both above and below a sedimentation basin.

Benthic Macroinvertebrates Assemblages in the Fish Pond
IOP Conference Series: Earth and Environmental Science, 2022 Overall, small holder of fish farmers in Kelantan in particular does not monitor their pond water quality to maintain fish health due to tedious and expensive work. Hence, this study was proposed to identify the assemblages of benthic macroinvertebrates at the fish pond for potential as a tool for water quality assessment via biological indicator.

Low flow controls on benthic and hyporheic macroinvertebrate assemblages during supra-seasonal drought [PDF]
, 2009 Despite the widely accepted importance of the hyporheic zone as a habitat for stream macroinvertebrates during floods, few data exist regarding community composition and distribution during periods of low flow or drought in perennial streamsi ...

A new substrate for sampling deep river macroinvertebrates [PDF]
, 2009 We compared macroinvertebrate communities colonising multiplate samplers constructed from perspex or tempered hardboard (wood) with an alternative artificial substrate constructed from folded coconut fibre matting (coir) enclosed in nylon netting ...
