Abstract
Six shrew communities of ten shrew species from open landscapes of Northern Asia were studied. The communities were characterized by similar structure, poor species composition, low number and low abundance. It was shown that the structure of shrew communities depended on the areas occupied by prairie, forested and wetland microlandscapes. The composition and dominance structure of the communities was affected by the landscape and geographical features of the habitat area. The study of population dynamics in northern Kazakhstan and in the south of West Siberia showed that two species of shrews demonstrated synchrony of population dynamics.
