Erythropoiesis dynamics in larvae of Rana macrocnemis Boulenger, 1885 (Ranidae, Amphibia) during their growth and development in mountainous Dagestan

Abstract: 

The article presents data on the dynamics of the erythrocyte content in the blood of the larvae of the brown frog Rana macrocnemis at stages 23–46 of their development (according to Gosner) in the highlands (Burshi village, Republic of Dagestan: 42°01'N, 47°03'E; 2250 m asl). Significantly high activity of erythropoiesis was revealed in the larvae of Rana macrocnemis. The number of erythrocytes in peripheral blood increases during the development of larval: from stage 23–24 to the completion of metamorphosis, their content rising by 42%. Erythropoiesis activation in early ontogenesis is primarily aimed at improving the supply of oxygen to cells in order to provide energy for cell proliferation and differentiation, growth, and development, as well as reflecting some specifics of adaptation to environmental conditions.
