[1] Analysis of soil and vegetation cover from satellite imagery to assess its relation to lark habitats (alaudidae, aves) in the trans-volga semi-desert / M. L. Oparin, Y. D. Nukhimovskaya, M. V. Konyushkova et al. // Biology Bulletin. — 2018. — Vol. 45, no. 10. — P. 1284–1292. This work was carried out in the Dzhanibek and Bokey Orda districts of the West Kazakhstan region of the Republic of Kazakhstan in two key areas. The possibility to study the relationship between the distribution of the abundance of various lark species and their nesting habitats detected using high-resolution satellite images, ground geobotanical descriptions, and bird counts on routes with a variable width of the accounting band was evaluated. The image heterogeneity in a snapshot was analyzed by cluster analysis in the ILWIS software (Heckbert quantization algorithm) using three rasters as variables: infrared and red channel images and NDVI. The correlation between the number of some lark species and the share of some plant associations in the band of accounting routes was established using correlation analysis and approximation of empirical distributions by theoretical ones. A reliable relationship was established between the distribution of three lark species living in the Trans-Volga semi-desert of the Caspian lowland with certain plant associations which they prefer to use as nesting stations.
