Abstract
Population dynamics (density, age structure, and sex ratio) of Sorex araneus and S. minutus was studied in late summers of 1987–1993 during small mammal community formation in a growing-up clear-cut area within a mixed forest in eastern Lithuania (Molėtai District; 55°09' N, 25°20' E). In the studied area the density of the common shrew was significantly greater and its multi-annual variation in density was more stable compared with the pygmy shrew (18.64 ± 2.49 and 5.57 ± 2.75 ind./ha, p < 0.0017; s = 0.258 and s = 0.625, respectively). Changes in the age structure (subadults/adults) and sex ratio of both shrew species correlated with density variations.
