Geographic information database for the analysis of spatial distribution of the Baikal endemic amphipods in Yenisei river
The purpose. The purpose of the work is the theoretical and practical studies of the possibilities for using the geoinformation web-system modern technologies for improving the efficiency of hydrobiological monitoring, and design of software tools of data presentation and analysis for field research. Methods. The technologies for development of distributed information systems in multi-tier architecture, along with software interfaces and protocols, information exchange standards are considered. The possibilities for using of geoinformation and cartographic modelling methods for searching the relationship between the spatial distributions of Baikal amphipods in the Yenisei river with different environmental factors are investigated. Results. The technologies and related software are developed for the considered problem. The geospatial database is generated and filled with the results of own longterm hydrobiological field studies, it has become an integral part of the geoportal of ICM SB RAS, which was formed by the separate thematic section. The focus is on the results of extensive field studies of the Yenisei implemented in 2015 and 2016. As to database content, the information about the quantitative distribution of zoobenthos (animals inhabiting the ponds bottom), in particular endemic Baikal amphipods, in the area from Yenisei river headwaters to its delta was used. It was revealed that the amphipods - the endemics of the Baikal lake - spread far beyond its limits not only downward, but also upstream the Yenisei river. After the commissioning of the Krasnoyarsk hydroelectric power station, their share in the total zoobenthos biomass is increased by 10 times. Gmelinoides fasciatus crustacean is especially active; it has massively populated the area of the Upper Yenisei river below the Sayano-Shushensky reservoir. The density and the fraction of crustaceans in the zoobenthos in the area of the Angara - Podkamennaya Tunguska has increased over the last 15 years. Conclusions. Creation of a geospatial database alongside with the results of expeditionary research and the introduction of a GIS web-system for information-analytical support of hydrobiological monitoring significantly expands opportunities for the analysis and presentation of geodata, forms the basis for interdisciplinary research.
