Adaptive Variability

In the Lower Irtysh basin there is rich diversity of the fish population, bream Abramis brama (Linnaeus, 1758) is one of the representatives. Having been introduced into the Ob’-Irtysh basin more than 100 years ago, it dispersed in most reservoirs due to its wide adaptive variability and high fecundity. In the process of fish introduction, the new types of parasites replenish the parasitic communities of water bodies. As a result of studying bream parasitic fauna after its distribution there has been stated a decrease in parasite species composition, in comparison with its maternal habitat. Studies conducted in 2017-2018 allowed to fund out infectiousness of bream with four types of monogeneans: Gyrodactylus elegans , Dactylogyrus falcatus , D. wunderi , D. zandti . There has been recorded 100% extensiveness of invasion by dactylogyruses. Extensiveness of invasion by G.elegans in 2017 amounted to 100%, in 2018 - 74.2%. The abundance index of G.elegans in 2018 decreased in comparison with 2017 and amounted to 55.9 and 83.4 specimens, respectively. Abundance index of Dactylogyrus spp. decreased in 2018 and amounted to 27.9 specimens, compared to 2017 when there were registered 55.9 specimens. In 2017, the examined bream individuals showed a total predominance of gyrodactyluses over dactylogyruses, whereas in 2018 the number of Dactylogyrus spp was higher than of G. elegans . The of infectiousness of bream was first established after its distribution in the Ob’-Irtysh basin, when it was infected by the specific monogenean - Dactylogyrus falcatus (Wedl, 1857).

Coordinated Water

The relevance of the study, due to the water difficult environmental situation increasing in the transboundary river basin (TRB) of Irtysh is related to the failure to address the issues of coordinated water use in the certain national segments: the Irtysh basin and its large left tributaries, the rivers Ishim and Tobol within the borders of Kazakhstan, China and Russia. The purpose of the study is to assess current processes of the water management system in the TRB formation and functioning, to identify current and potential problems of water use and to find ways to eliminate neutralize and prevent them in the future. The leading methods of research are system-dialectical, which provides for the water management systems study of the basin in question at the stage of formation, functioning and future development; as well as a comparative geographic method aimed at identifying and analyzing individual water management systems of the Irtysh TRB. Results of the study: The main water management problems in the Irtysh TBD were identified, their evaluation was determined and the their manifestation features in each of the identified national natural and economic subsystems were determined, the directions of their coordinated decision by all basin countries based on the methodology of strategic management adopted and widely implemented by the international scientific community. The significance of the study showed the severity of water management problems and the asymmetry of their solutions in different national segments of the Irtysh TRB, mainly due to incompleteness of the institutional environment for water resources management and inconsistency of the countries interests within its borders.

Geological Substrate

The possibility of use of the previously developed calculation technique of the North Rivers flow hydraulic records for the Ob River, the largest river in Russia by basin area, flowing under severe conditions in West Siberia was examined. The calculation technique is based on the model of heat and moisture exchange of the geological substrate with the Earth’s atmosphere, the Soil-Water–Atmosphere–Plants (SWAP) model, in conjunction with information support based on global databases of geological-substrate parameters and information obtained from observational data collected by weather stations within the Ob River basin. Uncertainty of the Ob River flow was assessed. Additionally, the ability of the SWAP model to reproduce multiyear dynamics from average values of snow reserves in the Ob-Irtysh basin was examined.
