objective: in this study, the effect of diet food (soybeans, egg yolk and chicken manure) on biomass weight and body composition (the amount of protein, fat, moisture and ash) chironomid larvae were examined. methods: for this purpose, 2.5 grams of food per coconut considered in the period, with three replicates and chironomid larvae during the period of 15 days in plastic pans were kept in nut...
To predict the response of aquatic ecosystems to future global climate change, data on the ecology and distribution of keystone groups in freshwater ecosystems are needed. In contrast to mid- and high-latitude zones, such data are scarce across tropical South America (Neotropics). We present the distribution and diversity of chironomid species using surface sediments of 59 lakes from the Andes ...
Increased hydrological connectivity due to permafrost degradation is likely have substantial implications for shallow aquatic systems common sub‐arctic landscapes changes overland and subsurface flow of water transport sediments dissolved nutrients. Here, we explore the influence increased on productivity based multi‐parameter palaeolimnological analysis two lakes located near Inuvik (Northwest...
Different types of water bodies in lowland river floodplains represent vital biodiversity havens and encompass diverse microhabitats, which are essential for structuring different macroinvertebrate communities. Chironomidae larvae (Diptera) an inseparable part these communities, with their high richness abundance. In three body within the Danube floodplain Kopa?ki Rit Croatia, over course four ...
Chironomidae is one of the most important elements of the aquatic benthos all over the world, which has its own ecological and biological importance in different aspects. The present study has been conducted to investigate the chironomid diversity in Taleghan River in two seasons, spring and summer 2016 for six sampling points (Asfaran, Varkesh, Mir, Jostan, Barikan and Gooran). The sampling pr...
Introduction: Chironomidae (Diptera) is the most widespread and abundant aquatic insect family in freshwater ecosystems. Chironomids are considered good indicators of water quality but seldom identified at genus level broad spatial scale studies. Objective: To identify environmental conditions associated with chironomids an altitudinal gradient. Methods: We compared ecoregions, river types, sea...
Sediment samples were collected in 4 sites along a salinity gradient (between 0.2 and 27.3) of the Aussa River (Marano Lagoon, northern Adriatic Sea, Italy) and a decreasing gradient of industrial contamination downstream (from Stn A1 to Stn A4) to assess how a riverine-lagoonal system responds to chemical contamination by applying an integrative measure of its benthic ecological properties. Be...
The occurrence and mass development of macroinvertebrates in drinking water networks is a challenge for pipe management. A current problem the larvae chironomid Paratanytarsus grimmii (mosquito), so-called pest organism that can have severe impacts on quality due to accumulation from parthenogenic reproduction, biofouling other aesthetic reasons. aim this study was develop new practical method ...
The recreational use of water bodies presents new challenges and pressures on lake ecosystems. We focused how beaches influence the shoreline biodiversity Lake Balaton, Hungary. Taking into account establishment beaches, we examined natural reed vegetated shorelines (representing situation), open areas areas, where has been removed), as well beaches. assessed abiotic parameters chironomid assem...
The Qu’Appelle Valley drainage system provides water to a third of the population of the Canadian Great Plains, yet is plagued by poor water quality, excess plant growth, and periodic fish kills. Fossil algae (diatoms, pigments) and invertebrates (chironomids) in Pasqua Lake were analyzed by variance partitioning analysis (VPA) to determine the relative importance of climate, resource use, and ...
