     Abstract: "The effects of total organic carbon (TOC) and UV-B radiation on Zn toxicity and bioaccumulation in a Rocky Mountain stream community were assessed in a 10-d microcosm experiment. We predicted that TOC would mitigate Zn [zinc] toxicity and that the combined effects of Zn and UV-B would be greater than Zn alone. However, TOC did not mitigate Zn toxicity in this study. In fact, treatments with TOC plus Zn had significantly lower community respiration as compared with the controls and Zn concentrations associated with the periphyton increased in the presence of TOC. UV-B had no additive effect on periphyton Zn accumulation or community respiration. Heptageniid mayflies (Ephemeroptera) were particularly sensitive to Zn, and reduced abundances were observed in all Zn treatments. UV-B did not additionally impact Heptageniid abundances; however UV-B did have a greater effect on macroinvertebrate drift than Zn alone. Ephemeroptera, Plecoptera, and Trichoptera (groups typically classified as sensitive to disturbance) were found in highest numbers in the drift of UV-B + Zn treatments. Measures of Zn accumulation in the caddisfly Arctopsyche grandis, periphyton biomass, and total macroinvertebrate abundance were not sufficiently sensitive to differentiate effects of TOC, UV-B, and Zn. These results indicate that UV-B and TOC affect Zn bioavailability and toxicity by impacting species abundance, behavior, and ecosystem processes. "

     The authors studied several genera of Heptageniidae not found in Colorado. Tolerances for neonicotinoid pesticides varied not only between genera, but also between populations of the same species in different locations. Quote from the abstract: "Our data suggest that populations of Heptageniidae mayflies can vary substantially in neonicotinoid tolerance. Population-level variation should be considered in toxicity assessments and presents the potential for evolved tolerance."

     Abstract: "Twenty-nine monophyletic species groups based on the study of nearly 200 species of the Ephemeroptera family Heptageniidae from North and Central America, Africa, Eurasia, and Southeast Asia were subjected to cladistic analysis in order to hypothesize their interrelationships and produce a framework for a strict phylogenetic higher classification for the family. As a result, three sequentially derived major clades are recognized as the subfamilies Ecdyonurinae, Heptageniinae, and Rhithrogeninae. The Ecdyonurinae is divided into four tribes: the Ecdyonurini, containing the genera Nixe Flowers and Ecdyonurus Eaton; the Leucrocutini, n. trib., containing the genera Siberionurus McCafferty and Leucrocuta Flowers; the Notacanthurini, n. trib., containing the genera Notacanthurus Tshernova and Electrogena Zurwerra and Tomka; and the Atopopini, n. trib., containing the genera Afronurus Lestage [=Cinygmina Kimmins, n. syn.], Asionurus Braasch and Soldán, Thalerosphyrus Eaton [=Compsoneuriella Ulmer, n. syn.; =Notonurus Crass, n. syn.], and Atopopus Eaton. The Heptageniinae is divided into four tribes: the Compsoneuriini, n. trib., containing the genera Compsoneuria Eaton and Trichogenia Braasch and Soldán; the Heptageniini, containing the genera Heptagenia Walsh, Dacnogenia Kluge, n. stat., and Raptoheptagenia Whiting and Lehmkuhl; the Kageroniini, n. trib., containing the genera Kageronia Matsumura [=Parastenacron Kluge, n. syn.] and Stenacron Jensen; and the Stenonematini, n. trib., containing the genera Macdunnoa Lehmkuhl, Maccaffertium Bednarik, n. stat., and Stenonema Traver. The Rhithrogeninae is divided into four tribes: the Rhithrogenini, containing the genera Paegniodes Eaton, Rhithrogena Eaton [=Rhithrogeniella Ulmer, n. syn.], and Cinygmula McDunnough [=Epeiron Demoulin, n. syn.; =Ororotsia Traver, n. syn.]; the Cinygmatini, containing the genus Cinygma Eaton [=Cinygmoides Matsumura, n. syn.]; the Epeorini, n. trib., containing the genera Bleptus Eaton, Ironodes Traver, and Epeorus Eaton [=Epeorella Ulmer, n. syn.]; and the Anepeorini, containing the genera Anepeorus McDunnough [=Acanthomola Whiting and Lehmkuhl, n. syn.] and Spinadis Edmunds and Jensen. The nomenclatural history of the higher classification of the family, bases for the new classification and synonymies, and the biogeography and evolution of the genera are discussed."
