Comparative assessment of the impact of pesticide pollution on the cytomorphology of erythrocytes Bufotes viridis (Laurenti, 1768) and Pelophylax ridibundus (Pallas, 1771) (Anura, Amphibia)

A comparative assessment of morphological features of erythrocytes Pelophylax ridibundus (Pallas, 1771) and Bufotes viridis (Laurenti, 1768) living near the territory sprayed with pesticides was carried out. Multidirectional changes in the parameters of erythrocytes in the compared species were revealed, expressed in an increase in the width, area and volume of cells in P. ridibundus and a decrease in the values of these parameters in B. viridis.

On the issue of the thermal adaptation of the larvae caucasian brown frog Rаna macrocnemis Boulenger, 1885 (Amphibia, Ranidae) to low-temperature environmental conditions

The results of the study of hematological parameters of the blood of the larvae caucasian brown frog Rana macrocnemis and the total activity of catalase compared with adults and at different temperature conditions: at 23°C and after five days of hypothermia at 5°C.
