LEUKOCYTIC INDICES AND MICRONUCLEUS IN ERYTHROCYTES AS POPULATION MARKERS OF THE IMMUNE STATUS OF PELOPHYLAX RIDIBUNDUS (PALLAS, 1771) (AMPHIBIA: RANIDAE) LIVING IN VARIOUS BIOTOPIC CONDITIONS

A differentiated assessment of blood cells and micronucleus species in the erythrocytes of marsh frogs (Pelophylax ridibundus) living in reservoirs of the Nizhniy Novgorod region and differing by origin, morphology and chemical composition was performed. Specific abiotic conditions (a peat bog) and anthropogenic load led to the most expressed change of the leukocyte composition of the blood, corresponding to the neutrophilic type of leukemoid reaction and an increased fraction of micronucleus in the erythrocytes.
