英文摘要	The results of long-term studies on chironomids (Diptera: Chironomidae) in macrozoobenthos communities in five saline rivers of the hyperhaline Lake Elton basin, Volgograd Region are presented. The arid zone of the south of Russia is unique due to specific environmental conditions. Saline rivers are distinguished by size and the spatial dynamics of hydrological, hydrochemal and hydrophysical characteristics; they have a high mineralization gradient ranging from 6 to 41.4 g L-1. In the estuaries of the rivers, the degree mineralization can exceed 100 g L-1. As many as 25 species of chironomids and other taxa collected from brackish and saline rivers (Khara, Lantsug, Bolshaya Samoroda, Chernavka, Solyanka) in 2006-2014 were identified. Ten species mainly inhabit the Solyanka and Chernavka rivers with a salinity level above 20 g L-1. The species Chironomus aprilinus Meigen 1838, C. salinarius Kieffer 1915 and Cricotopus salinophilus Zinchenko, Makarchenko et Makarchenko 2009 prevailed in abundance in the Chernavka and Solyanka rivers, while the chironomids Tanytarsus kharaensis Zorina et Zinchenko 2009 dominated in the Khara and Bolshaya Samoroda rivers. The chironomids of the bottom communities in the saline rivers were represented by eurybiont halo-tolerant species. Their structural, temporal and spatial variations was associated with habitat factors. The taxonomic structure of the chironomid communities in eutrophic saline rivers was shaped by the spatial heterogeneity of habitats and abiotic factors such as the content of individual anions and cations (SO42-, Cl- Na+ + K+), nutrients in the form of mineral phosphorus (PO43--P) etc. The species distribution and abundance were regulated by hydrological and hydrophysical factors (algae blooms, water temperature, pH, granulometric composition of the ground etc.). The diversity of chironomids correlated closely with mineralization levels, whereas the abundance and biomass of chironomids in relation to the mineralization range of 6-41.4 g L-1 was not significant. The seasonal dynamics of the abundance and biomass of chironomids was characterized by the spatial heterogeneity of peaks in a mesohaline river associated with the emergence of imaginal stages of abundant species. This was related to the specific life cycles of amphibiotic insects that shape the structure of benthic communities in saline rivers.
