The Preliminary Ecological-Faunistic Data about Fungivorous Beetles (Insecta: Coleoptera) of Saratov Province

Until this article in the Saratov Province special studies of fungivorous beetles fauna of Coleoptera was carried out.

Dynamics of the Number and Current State of Population Red-footed Falcon (Falco Vespertinus Linnaeus, 1766) in the North of the Lower Volga Region

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.
