AbstractThe ecological and geographical regularities of the spatial differentiation of the fauna of birds and mammals in the seas of northeastern Russia were studied at the end of the winter period of 1987–1988. The aerial surveys covered the Bering, Chukchi, and East Siberian Seas and the eastern part of the Laptev Sea. Mammals are ecologically as...

AbstractAccording to the results of bird counts carried out in 140 habitats over 12 years, a hierarchical classification and a structural graph of the similarity of ornithocomplexes in the lowland southwestern part of Western Siberia and North Kazakhstan have been compiled in the period from 1982 to 2002. The hierarchical classification contains te...

AbstractThe dramatic rise of human population growth and urban development, especially in developing countries, has led to a decline in the quality, fragmentation and isolation of habitats which support rare or endangered fauna species. New areas designed to protect such species and form corridors and networks to support populations are needed. Two...

AbstractThe paper analyses the influence of floristic structure, vegetation density and nutrient content on the occurrence and abundance of invasive species in aquatic vegetation communities in canal network in Serbia. The results of Shannon–Weaver index of diversity, index of evenness, Steinhaus index of floristic similarity, correlations between ...

AbstractThis article presents the history of large oil spills in freshwaters, considering the processes of physicochemical and biological degradation of oil. It discusses the toxicity of oil for hydrobionts and effects of oil pollution on communities of plankton, benthos, and ichthyofauna, as well as challenges in mitigating the environmental impac...

AbstractThis work contains an analysis of the total content of petroleum products (hydrocarbons) in samples and columns of bottom sediments (BS) of the Noril’skaya–Pyasino group of water objects contaminated as a result of a diesel fuel spill from the CHPP-3 reservoir at AO NTEC near Norilsk. Two methods—fluorimetry and gas chromatography—have been...

Abstract—The species composition and quantitative characteristics of the zoobenthos in Lake Pyasino and rivers flowing into it after a diesel spill have been analyzed. The production of zoobenthos and potential production of benthivorous fish in Lake Pyasino have been calculated. A small number of zoobenthos species and low values of abundance and ...

AbstractThe bacterial composition of water and sediments in Lake Pyasino and adjacent rivers has been studied by high-throughput sequencing for the first time. No hydrocarbon-degrading bacteria are found in the river sections exposed to the diesel spillage in May 2020. The Daldykan and Ambarnaya rivers, located downstream of the spill site, are dom...

Abstract—An assessment of the species composition, abundance, biomass, and pigment characteristics of phytoperiphyton and phytoplankton of Lake Pyasino, its tributaries (Bezymyannyi Stream, Daldykan, Ambarnaya, and Norilskaya rivers), and the head of the Pyasina River has been carried out after a manmade accident (a diesel-fuel spill near the city ...

AbstractThe results of a hydrochemical analysis of the consequences of an accidental fuel release in the Norilsk–Pyasino water system are presented. The pollution of watercourses in the catchment of Lake Pyasino (a nameless (Nadezhdinsky) creek, the Daldykan River, and the Ambarnaya River) with oil products, phenols, easily oxidizable and hard to o...
