Load of nutrients and organic substances of the Don River basin (Severskyi Donets sub-basin) [PDF]
Formulation of the problem. The main danger of organic substances is the use of large amounts of oxygen for its oxidation. As a result, there are conditions of oxygen deficiency in polluted water sometimes to the formation of hypoxia.

Review of the cellulose acetate peel method and the physical and digital curation of coal balls. [PDF]
Abstract Coal balls, in which fossil plants are preserved in permineralized peat deposits, have widely been described from coal deposits representing the tropical forest of the Carboniferous. Coal ball preparation techniques have evolved over the past century, with the cellulose acetate peel method becoming the standard in the 1950s.

Unclear host taxonomy hinders parasite studies: An up-to-date checklist of the protozoan and metazoan parasites of Phoxinus minnows (Teleostei: Leuciscidae). [PDF]
Abstract Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas ...
