| Abstract: | We studied the abundance, spatial structure, and demographic parameters of the Transvolga population of the great bustard and the connections of this species to habitats during relocations preceding migration. The data were obtained by monitoring a test area of 1 200000 hectares in 1998–2000. Time-related changes in the structure of great bustard habitats in the Saratov Transvolga Region in the 20th century are described, and the mechanisms underlying changes in the species connection to habitats under the influence of anthropogenic factors are proposed. |
