Abstract
Long-term monitoring of helminth communities in rodents of small-leaved woods in Northern Baraba ( Novosibirsk area) was carried out. It was established that the fractions of vole populations infected with nematoda Hepaticola hepatica (Bancroft, 1893) Hall, 1916 are: 32,1 % - Arvicola terrestris, L., 1758; 9,1 % - Microtus agrestis, L., 1761; 3,1 % - M oeconomus, Pall., 1776 ; 2,6 % - Clethrionomys glareolus, Schreb, 1780; 2,2 % - C. rutilus, Pall., 1779 and 0,9 % of Apodemus agrarius, Pall., 1771. It is shown that during the mass reproduction of water vole it occupies the dominant position in the structure of rodent community and has major importance in the realization of the life cycle of the parasite. During its low number, the centers of H. hepatica infection in the biosenosis are supported by M. agrestis and C. glareolus voles.
