摘要
In the present study, the data for population dynamics of micromammalia in Dnipropetrovs＇k Region in 1957-1999 and Dnipro-Orel＇s Natural Reserve at 1991-2009 are adduced. With the purpose to drawing up of the long-term forecast at number are analyzed long-term lines of number on background kind＇s fine micromammals of dominant group. The analysis of long standing rows of number small mammals and comparison data with Wolf number were demonstration, which indicate that dynamic of number phone species （and dominant in particular） carry a cyclic character and contact with 11-year cycles of sun activity. Consequently, it was clearing up hidden periodical in dynamic of number mouse rodents. By that observation was dependence from cycles of sun activity. Probably, that in 2012 year, before peak of sun activity in 2013, next high increase about the number of small mammals for maxima （＂outbreak＂ mass reproduction is a peak ＂big wave＂） will take place.
