Korneev A.G., Verschagin N.N., Sankov D.I., Pan'kov A.S., Mikhajlova N.R. POPULATION CHARACTERISTICS OF DOMINANT SMALL MAMMALS SPECIES, AND IMPACT PRODUCED BY THEM ON INCIDENCE OF HEMORRHAGIC FEVER WITH RENAL SYNDROME AMONG POPULATIONThere are natural foci of hemorrhagic fever with renal syndrome in the territory of the forest-steppe and steppe landscapes. The populations of small mammals circulates Hantavirus Puumala. The purpose of the work — an example of the Orenburg area to determine the number of dominant species of small mammals and assess their impact on the incidence of hemorrhagic fever with renal syndrome population of steppe and forest-steppe zones. Analysis of the parameters of the population of small mammals was conducted over the years 1992–2013 according to the spring and autumn catches. We studied the species composition and numbers. By dominant types of small mammals in the forest steppe zone includes Myodesglareol, Apodemusuralensis and Musmusculus, and in the steppe zone — only Myodesglareolus and Musmusculus. In the steppe zone in the absence of significant changes in the long-term population dynamics of Apodemusuralensis showed a tendency to increase the number of. In the forest-steppe zone of dominant population remained stable from year to year. The increase in the number of Myodesglareolus from spring to autumn in the steppe zone occurred more rapidly than in the steppe zone. Significant correlations between the number of dominant species on the results of the spring catches and morbidity of hemorrhagic fever with renal syndrome in both zones were absent. Revealed correlations between the incidence of moderate strength and number of the Myodesglareol fall, and in the forest-steppe zone and Musmusculus. This supposedly determines the leading role of these species in the infected person in the study area.Key words: dominant species, number of small mammals, hemorrhagic fever with renal syndrome.
