Accumulation and effects of cyanobacterial microcystins and anatoxin-a on benthic larvae of Chironomus spp. (Diptera: Chironomidae)

open access: yesEuropean Journal of Entomology, 2014
Larvae of Chironomidae are distributed world-wide and are very abundant in eutrophic water bodies affected by cyanobacterial blooms. However, there is little information on the effect of cyanobacteria and their metabolites on these aquatic organisms. Our

Complete mitochondrial genome of the non-biting midge Polypedilum henicurum Wang, 1995 (Diptera: Chironomidae)

open access: yesMitochondrial DNA. Part B. Resources, 2023
The complete mitochondrial genome of Polypedilum henicurum was sequenced and analyzed. The whole mitogenome is 15,964 bp in length and contains 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), and two ribosomal RNAs (rRNAs).

Studies in South-Occidental Amazon: contribution to the knowledge of Brazilian Chironomidae (Insecta: Diptera)=Estudos na Amazônia Sul-ocidental: contribuição para os conhecimentos sobre Chironomidae (Insecta: Diptera) no Brasil [PDF]

open access: yesActa Scientiarum: Biological Sciences, 2012
Chironomidae (Diptera) are a diverse and large group of small flies, whose larvae inhabit nearly every possible niche in most freshwater aquatic ecosystems. The Acre river is an important affluent of the Purus river.

Genomic alterations recorded in two species of Chironomidae (Diptera) in the Upper Jurassic limestone area of the Ojców National Park in Poland attributable to natural and anthropogenic factors

open access: yesEuropean Journal of Entomology, 2012
The Ojców National Park is situated in southern Poland in an area of Jurassic limestone, which determines the hydrochemistry of the water in the River Prądnik. The geochemical index of the sediment in the River Prądnik indicated it is moderately polluted

Comparative mitogenome analyses of twelve non-biting flies and provide insights into the phylogeny of Chironomidae (Diptera: Culicomorpha)

open access: yesScientific Reports, 2023
The family Chironomidae is represented by seven subfamilies in China, among which Chironominae and Orthocladiinae are the most diverse. To gain a better understanding of the architecture and evolution of the mitogenomes of Chironomidae, we sequenced ...

Are macrophyte-dwelling Chironomidae (Diptera) largely opportunistic in selecting plant species?

open access: yesEuropean Journal of Entomology, 2012
In this study we evaluate how variations in taxonomic composition and physical structure of macrophyte stands affect plant-dwelling chironomid assemblages in highly variable macrophyte assemblages in two densely vegetated backwaters.

Urban‐driven homogenization of aquatic subsidy size structure cascades to riparian predator communities

open access: yesOikos, EarlyView.
The export of emergent aquatic insects is a critical energy subsidy for terrestrial food webs. While urbanization is known to alter stream communities, its effects on the size structure of these insect subsidies and the subsequent consequences for riparian predators remain poorly understood.

Ecological Characteristics of Stream Reaches With and Without Low‐Tech Process‐Based Restoration in a Wildfire‐Affected Catchment

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that
