Hemoglobin affinity for oxygen in three subspecies of toads (Bufo sp.) living at different altitudes

Ostojic, H; Monge-C, C; Cifuentes, V

Abstract

Blood oxygen affinity and red blood cell properties were measured in three subspecies of genus Bufo: Bufo spinulosus limensis, collected at sea level and at an average day temperature of 20 degrees C; Bufo spinulosus trifolium, from 3100 m, average day temperature of 15 degrees C; and Bufo spinulosus flavolineatus, from 4100 m, average day temperature of 10 degrees C. Electrophoresis of the hemoglobin showed the same component in each of the three subspecies. At 20 degrees C the blued oxygen affinities (P-50) showed small differences between Bufo spinulosus limensis and Bufo, spinulosus trifolium, whereas the value for Bufo spinulosus flavolineatus was markedly lower. At 10 degrees C, the ambient temperature of Bufo, spinulosus flavolineatus, the P-50 was extremely low compared with the other two subspecies at their corresponding ambient temperatures.
