... examined at 30, 20 and 10 °C. In addition, skeletal muscle ion concentrations were examined in black racer snakes ( Coluber constrictor ) at 30 and 10 °C. Cooling the amphibians produced a reduction in most of the plasma ion concentrations (Na + , K + , Ca 2+ , Cl − , SO 4 2− ) and in protein concentration...

... racer snakes Coluber constrictor . When the temperature was reduced from 30 to 10 °C, pH increased slightly (by −0.0028 pH units °C−1), decreased by 7 mmHg, [CO 2 ] increased by 3.2 mmol l−1 and [HPO 4 2−+H 2 PO 4 −] increased by 0.7 mmol l−1. Concentrations of protein and of the remaining electrolytes...

... in temperature have previously been reported for the snake Coluber constrictor . The purpose of the present study was to determine the ventilatory and pH adjustments associated with the increase in CO 2 stores when the snakes are cooled. Body temperature was lowered from 30 to 10 °C within 4 h, at which time...

...Bruce C. Jayne; James D. Davis ABSTRACT We used a motorized treadmill to determine the endurance (from 4.2 to 5.6cm s −1 ) and burst speed of five Coluber constrictor Linnaeus performing concertina locomotion in tunnels 3, 5 and 7cm wide. The snakes had greatest average endurance at 4.2cms −1...
