“…Previous studies show that chironomid ventilation is affected by xenobiotics like insecticides and waterborne Hg (LangerJaesrich et al 2010; Azevedo-Pereira and Soares 2010), but also by naturally varying conditions like temperature and oxygen saturation (Roskosch et al 2012). In the present study, chironomid larval mortality did not differ between the exposures, this result being consistent with West et al (1996), who did not detect any effects of TCDD on chironomid growth, emergence rate or fecundity.…”

. (2016). Biological responses of midge (Chironomus riparius) and lamprey (Lampetra fluviatilis) larvae in ecotoxicity assessment of PCDD/F-, PCB-and Hg-contaminated river sediments. Environmental Science and Pollution Research, 23 (18), 18379-18393. doi:10.1007/s11356-016-7014-5 Abstract We evaluated utility of chironomid and lamprey larval responses in ecotoxicity assessment of polychlorinated dibenzo-p-dioxins, dibenzofurans (PCDD/F)-, polychlorinated biphenyls (PCB)-and mercury (Hg)-contaminated river sediments. Sediment samples were collected from the River Kymijoki with a known industrial pollution gradient. Sediment for the controls, and lamprey larvae were obtained from an uncontaminated river nearby. Contamination levels were verified with sediment and tissue PCDD/F, PCB and Hg analyses. Behaviour of sediment exposed chironomid and lamprey larvae were measured with Multispecies Freshwater Biomonitor© utilizing quadrupole impedance conversion technique. In addition, mortality, growth and head capsule deformity incidence of chironomids were used as ecotoxicity indicators. WHO PCDD/F+PCB -TEQ in the R. Kymijoki sediments ranged from the highest upstream 22.36 ng g -1 dw to the lowest 1.50 ng g -1 near the river mouth. Sum of PCDD/Fs and PCBs correlated strongly with Hg sediment concentrations, which ranged from <0.01 to 1.15 µg g -1 . Lamprey tissue concentrations of PCDD/Fs were two orders and PCBs one order of magnitude higher in the R. Kymijoki compared to the reference. Chironomid growth decreased in contaminated sediments, and was negatively related to sediment ∑PCDD/Fs, WHO PCDD/F+PCB -TEQ and Hg. There were no significant differences in larval mortality or chironomid mentum deformity incidence between the sediment exposures. The distinct behavioural patterns of both species indicate overall applicability of behavioural MFB measurements of these species in sediment toxicity bioassays. Chironomids spent less and lampreys more time in locomotion in the most contaminated sediment compared to the reference, albeit statistically significant differences were not detected. Lamprey larvae had also a greater activity range in some of the contaminated sediments than in the reference. High pollutant levels in lamprey indicate risks for biomagnification in the food webs, with potential health risks to humans consuming fish.Keywords: polychlorinated dibenzo-p-dioxins and -furans; polychlorinated biphenyls; mercury; sediment toxicity; Chironomus riparius; Lampetra fluviatilis; behaviour AcknowledgementsWe thank Tino Hovinen (University of Jyväskylä) and Rauni Kauppinen (Finnish Environment Institute) for their valuable help in the field and laboratory, and researchers in the National Institute of Health and Welfare for PCDD/F and PCB analyses.

“…Based on impacts of dreissenids (e.g., Strayer 2009), the filter-feeding activity of other benthic invertebrates can be expected to exert a relevant feeding pressure on the phytoplankton community, and perhaps small zooplankton, and hence affect the entire planktonic community. Roskosch et al (2012) showed the existence of seasonal and temperature-dependent variation in chironomid metabolism and filter-feeding activity, resulting in somewhat higher ventilation rates during summer. However, in contrast to zooplankton, for which the overall feeding activity is dependent on both temperature and population density, the feeding pressure by benthic invertebrates is less dynamic throughout the year because there is usually less seasonal variation in population density due to overlapping generations and species (e.g., Armitage et al 1995, Ho¨lker and Breckling 2002, Roskosch et al 2010b; Fig.…”

“…Small-scale laboratory studies investigating the pumping activity of tube-dwelling invertebrates (ventilation; see Table 1 for definition of terms) and the subsequent aeration of the sediment (bioirrigation) suggest that tube-dwelling invertebrates play a far more important and diverse ecological role than previously assumed by ecosystem-level analyses. Volumes equivalent to an entire shallow lake can be pumped through the sediment on timescales of days to weeks (Roskosch et al 2012). This is particularly true for the most widely distributed and frequently the most abundant group of insects in freshwater environments: the family Chironomidae, dipterans in the suborder Nematocera.…”

Abstract. There is ample evidence that tube-dwelling invertebrates such as chironomids significantly alter multiple important ecosystem functions, particularly in shallow lakes. Chironomids pump large water volumes, and associated suspended and dissolved substances, through the sediment and thereby compete with pelagic filter feeders for particulate organic matter. This can exert a high grazing pressure on phytoplankton, microorganisms, and perhaps small zooplankton and thus strengthen benthic-pelagic coupling. Furthermore, intermittent pumping by tube-dwelling invertebrates oxygenates sediments and creates a dynamic, three-dimensional mosaic of redox conditions. This shapes microbial community composition and spatial distribution, and alters microbe-mediated biogeochemical functions, which often depend on redox potential. As a result, extended hotspots of element cycling occur at the oxic-anoxic interfaces, controlling the fate of organic matter and nutrients as well as fluxes of nutrients between sediments and water. Surprisingly, the mechanisms and magnitude of interactions mediated by these organisms are still poorly understood. To provide a synthesis of the importance of tube-dwelling invertebrates, we review existing research and integrate previously disregarded functional traits into an ecosystem model. Based on existing research and our models, we conclude that tube-dwelling invertebrates play a central role in controlling water column nutrient pools, and hence water quality and trophic state. Furthermore, these tiny ecosystem engineers can influence the thresholds that determine shifts between alternate clear and turbid states of shallow lakes. The large effects stand in contrast to the conventional limnological paradigm emphasizing predominantly pelagic food webs. Given the vast number of shallow lakes worldwide, benthic invertebrates are likely to be relevant drivers of biogeochemical processes at regional and global scales, thereby mediating feedback mechanisms linked to climate change.

Abstract:The purpose of this work was to reveal the Chironomid larvae bioturbation impact on N release and to find the mechanism of bioturbation to N conversion at the SWI (sediment-water interface). Sampling at four points during a 35-day incubation experiment was conducted. Two in situ techniques (microelectrode and Peeper) were used to capture more realistic and accurate microenvironment information around U-shaped corridors. The results demonstrate that the concentrations of ammonia nitrogen (NH 4 + ) and nitrate nitrogen (NO 3 − ) decreased by 21.26% and 19.50% in sediment and increased by 8.65% and 49.82% in the overlying water compared to the control treatment, respectively. An inverse relationship was observed between NH 4 + and NO 3 − concentrations in pore water in Chironomid larvae treatment, and they were significantly negatively/positively correlated with AOB (ammonia-oxidizing bacteria) abundance, respectively. This study confirmed that the Chironomid larvae bioturbation promoted the N (NH 4 + and NO 3 − )release from sediment by in situ techniques, and a part of NH 4 + converted into NO 3 − during their flow into the overlying water through the nitrification affected by AOB. Furthermore, the main depth of bioturbation influence is approximately 12 cm below the SWI and the most significant bioturbation effect was observed from days 15 to 25.
