Benthic macroinvertebrates as indicators of water quality: The intersection of science and policy
TL;DR: In this article, a review addresses the intersection of water quality policy and benthic macroinvertebrates and highlights policy-relevant research questions that would further aid the classification of impaired waters, the identi cation of stressors, or the management of stream ecosystems.

Temporal and spatial responses of Chironomidae (Diptera) and other benthic invertebrates to urban stormwater runoff
TL;DR: In this article, a longitudinal study of two streams whose lower reaches received unattenuated urban stormwater runoff, physical disturbance by stormflow was less important than the persistant unidentified chemical impacts of urban storm water in limiting the distribution of Chironomidae, and Ephemeroptera, Trichoptera and Plecoptera (EPT).
Periphyton Patch Preference in Grazing Chironomid Larvae
Susan E. Gresens,Rex L. Lowe +1 more
TL;DR: The feeding preference of chironomid larvae was determined by observing dispersal of larvae among patches differing in periphyton composition by using nutrient-diffusing substrates to generate four algal patch types, which differed in the abundance of several diatom species and the green alga Stigeoclonium.

TL;DR: It is concluded that sequence data from neutral nuclear markers will be necessary to determine if these two species are genetically distinct species, or whether there is merely a high level of environmental plasticity in pigmentation within this geographically widespread barcode cluster.

TL;DR: The distribution of imperiled stream fish, crayfish, salamander, and freshwater mussel species of Maryland streams in relation to urban land cover and nonnative species was investigated.
