Ontogenetic change in molecular and functional properties of blood of garter snakes, Thamnophis sirtalis
(Wiley: Journal of Experimental Zoology, 1977-07)
At birth the blood of garter snakes (Thamnophis sirtalis) has high oxygen affinity (P50 at 25°C and pH 7.2 = 21 mm Hg), low hematocrit (14%), and a high proportion of inactive hemoglobin (44%). Growth of the snakes is ...
Ontogenetic change in blood oxygen capacity and maximum activity in garter snakes (Thamnophis sirtalis)
(Springer: Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1977-01)
There is an ontogenetic increase in the time that garter snakes (Thamnophis s. sirtalis) can maintain maximum activity at 25°C. Newborn snakes are exhausted by 3–5 min of activity while adults can be active for 20–25 min. ...
