Authors: Mosolova E. Y., Tabachishin V. G., Serebryakova S. Y.

The abundance dynamics of Falco vespertinus is considered on the basis of our field surveys carried out within the Saratov region and adjacent territories in 2011–2016 and analysis of the literature data. It is shown that F. vespertinus is now presented by stable populations in the spacious territory of the Trans-Volga part of the region. However, some reduction of its abundance was registered here for the last several decades of the 20th century. Currently, the falcon populations in the Volga right-bank region can be characterized as mosaic, and the F.

To Biology of a Rare Species of Primula Farinosa L. in Ritsinsky Relic National Park (Abkhazia Republic)

Authors: Mustafina A. N., Abramova L. M., Тания И. В.

Research of eight populations of a rare species Primula farinosa L (syn. Р. algida auct. fl. colch.) in Ritsinsky relic national park (Abkhazia Republic) is conducted. The studied coenopopulations are located at the height of 1645–2250 m above sea level. Total number of species in them makes about 2200 pieces. In the majority of morphometric parameters coenopopulations from the natural boundary Pyv. On vital state three populations are carried to prospering, two – to equilibrium and three populations depressive. Optimum conditions for growth of Primula farinosa are defined.
