The Space Linkage between of Anomales of Density of Birds and Mammals’ Species and Entropy of River Basins Landscapes of the South Part of Volga Upland

Peculiarities of the linkage between specific birds and mammals density anomalies and entropy of river basins landscapes were investigated. Using mapping methods it has been found that positiv anomalies are concentrated in slopes of Volga-Don, Tereshka-Sura and Tereshka-Tersa watersheds and Medveditsa river valley; the negative ones are connected with agrocenosises of Chardym, Kurdum fnd Shiroky Karamysh rivers valleys.
