ANALYSIS OF RELATIONSHIP OF CHANGES OF BIODIVERSITY, OXYGEN CONTENT IN ATMOSPHERE AND MASS OF CARBON-HYDROGEN STRATUM OF LITHOSPHERE IN THE PHANEROZOIC // Tomsk State Pedagogical University Bulletin. 2012. Issue 7 (122). P. 153-156

Relationship between changes of biodiversity with oxygen content in atmosphere and mass of carbon-hydrogen stratum in the Phanerozoic is studied. Dynamics of biodiversity is represented by the cyclical changes of species diversity of sea animals in the Phanerozoic. Information about changes of sea animal biodiversity in the Phanerozoic was taken from Sepkosky database. The relationship between cyclical changes of oxygen content in atmosphere, mass of carbon-hydrogen stratum and changes of sea animal biodiversity in the Phanerozoic is revealed on base of temporal sets analysis of the above mentioned quantities. The revealed relationships were proved by correlation calculations.

Keywords: Phanerozoic, biodiversity, number of sea animals species, oxygen in atmosphere, carbon-hydrogen stratum of lithosphere

LANDSCAPE-SPACE ANALYSIS OF DYNAMICS THERMOKARST LAKES FIELDS IN ZONE PERMAFROST OF WEST SIBERIA // Tomsk State Pedagogical University Bulletin. 2012. Issue 7 (122). P. 167-170

Methodological questions of thermokarst lakes landscape dynamics in West Siberian permafrost territory based on remote sensing data and GIS-tools are considered. The data about relative change of thermokarst lake total area are given for 35-year period in different landscape zones and subzones. Possible factors of thermokarst lake areas change are discussed.
