The structure and dynamics of common dormouse (Muscardinus avellanarius L.) populations in Lithuania /

Abstract

During 1984-1993 investigations on the structure and dynamics of two isolated M. avellanarius populations were carried out in Lithuania. At site A average population density in spring was 1.0 individuals/ha (0.7 ind/ha at site B); males comprised 50% (47%) of the population. One-year-old, two-year-old, three-year-old and four-year-old dormice comprised 67%, 24%, 8% and 1% (70%, 23%, 5% and 2%) respectively. In autumn average population density was 3.0 individuals/ha at site A (2.4 ind/ha at site B), young made up 69% (74%) of the total population. Fifty five percent (60%) of all females were reproductively active. Males comprised 52% (48%) in the litters. Average mortality during hibernation was 68% (71%). The present paper reviews dynamics and correlation of these indices
