THE ECO-PHYSIOLOGICAL STATUS OF HIBERNATING BATS (CHIROPTERA) IN THE NORTH OF THE EUROPEAN DISTRIBUTION RANGE
Keywords: BATS, HIBERNATION, RESISTANCE, ANTIOXIDANT SYSTEM, LDH ISOENZYME SPECTRA, LEUKOCYTES
The chiropteran fauna in hibernacula in Karelia is chiefly made up of widespread sedentary boreal species – the northern bat Eptesicus nilssonii (Keyserling & Blasius, 1839), Brandt's bat Myotis brandtii (Eversmann, 1845) and brown long-eared bat Plecotus auritus (Linnaeus, 1758). The Daubenton's bat M. daubentonii (Kuhl, 1817) and especially the whiskered bat M. mystacinus (Kuhl, 1817) are far more rare, and wintering of the pond bat M. dasycneme (Boie, 1825) and the Natterer's bat M. nattereri (Kuhl, 1817)has not yet been confirmed. The comparative study of the immune status, antioxidant system and lactate dehydrogenase (LDH) isoenzyme spectra in tissues (liver, heart, kidney, lung, spleen and skeletal muscle) of three Chiroptera species during hibernation was conducted. It was revealed that torpor drastically reduced the numbers of all types of circulating leukocytes. In addition, changes have been noted in the antioxidant system, such as the relatively high antioxidant protection displayed by their tissues, considering both constitutive antioxidant enzymatic activities and nutritional antioxidants. The LDH isoenzyme spectra in bat kidneys and heart had a high content of hybrid fractions. Superoxide dismutase and catalase activities, vitamin E levels and leukocyte differential count were significantly different in three bat species. The differences may be due to the species-specific biological and eco-physiological features.
