TL;DR: Hydrologic and geomorphic factors influenced assemblages at the macroscale, whereas microhabitat diversity dominated at the mesoscale.
Abstract: The abundance and richness of macroinvertebrates in the lower Murray and Darling rivers were examined at a macroscale (rivers), mesoscale (billabongs, backwaters, channel) and microscale (vegetation, snags, substrata). In the Darling, insects dominated (85% of taxa, 81% of individuals); the richest taxa were Diptera (26 taxa) and Coleoptera (15 taxa) and the most abundant were Hemiptera (47%) and Diptera (35%). In the Murray, insects again dominated (84% of taxa, 52% of individuals), particularly Diptera (22 taxa), Coleoptera (12 taxa) and Hemiptera (9 taxa), but there were more crustaceans (9% of taxa, 47% of individuals, particularly the atyid shrimp Paratya australiensis). Both assemblages were uneven: in the Darling, >50% of biomass was Micronecta spp. (Corixidae), Dicrotendipes sp. (Chironomidae) and Macrobrachium australiense (Palaemonidae); in the Murray, 70% of biomass was P. australiensis and Caridina mccullochi (Atyidae) and the insects Micronecta spp. (Corixidae) and Chironomus sp. (Chironomidae). Abundances generally were greatest in the Murray. Hydrologic and geomorphic factors influenced assemblages at the macroscale, whereas microhabitat diversity dominated at the mesoscale.

TL;DR: An extensive survey of the benthic macroinvertebrate fauna of the heavily polluted Buffalo River (New York) Area of Concern, with specific emphasis on assessment of morphological deformities of aquatic larval midges (Chironomidae: Diptera), provides one biologically relevant measure against which to gauge the effectiveness of pollution abatement strategies within the AOC.

TL;DR: A repeated series of benthic surveys across the impacted range in southern Thailand from Ranong to Krabi, including unimpacted control sites, has enabled identifi cation of the associated insects, allowing detection of biotic responses.
Abstract: One environmental consequence of the December 2004 Indian Ocean tsunami was the inundation with seawater of many water bodies along the affected coastal plain. A repeated series of benthic surveys across the impacted range in southern Thailand from Ranong to Krabi, including unimpacted control sites, has enabled identifi cation of the associated insects, allowing detection of biotic responses. tifi cation of the associated insects, allowing detection of biotic responses. tifi Larval Chironomidae (Diptera) were diverse, with 29 species identifi ed, belonging to 15 genera in three subfamilies. The genus Conochironomus Freeman is reported formally for the fi rst time from the region. The larval differentiation of the dominant genus, Kiefferulus Goetghebuer (comprising three species), is established here for the fi rst time. fi rst time. fi Kiefferulus longilobus (Kieffer) is restricted to the most saline impacted sites where it is the only chironomid present; congeners K. calligaster Kieffer and er Kieffer and er K. barbatitarsis Kieffer are associated with 'recovery' sites of high but reducing conductivities. The multispecies genera Dicrotendipes Kieffer, Polypedilum Kieffer and Tanytarsus v. d.Wulp show varying patterns of association with impact and recovery. Ranges of conductivity and dissolved solids are provided for all species of Chironomidae. Illustrated keys are provided to allow identifi cation of all species recovered.

TL;DR: The diets of 17 genera were investigated, and the majority of the individuals were classifi ed as collectors, and Ablabesmyia was the only genus that exhibited items of animal origin in the diet.
Abstract: Feeding habits of Chironomidae larvae (Insecta: Diptera) in Vargem Limpa stream, Bauru, SP, Brazil. The present study analyzed the feeding habits and structure of the Chironomidae fauna in Vargem Limpa stream, in December 2004. The main food item ingested by most of the analyzed genera (Beardius, Caladomyia, Chironomus, Clinotanypus, Corynoneura, Cricotopus, Cryptochironomus, Dicrotendipes, Endotribelos, Harnischia, Fissimentum, Lopescladius, Polypedilum, Tanypus and Tanytarsus) was identifi ed as detritus, except for the Cladopelma whose main food item was algae. Ablabesmyia was the only genus that exhibited items of animal origin in the diet. The diets of 17 genera were investigated, and the majority of the individuals were classifi ed as collectors.
