1. When the ambient oxygen tension of the water was lowered, unrestrained shore crabs acclimated to 15, 20 and 25°C emerged into air to ventilate the branchial chambers when the inspired oxygen tension ( $$PI_{O_2 }$$ ) was reduced to mean values of 37±4 mmHg, 51±6 mmHg and 119±3 mmHg respectively. There is a positive correlation between $$PI_{O_2 }$$ at emersion and acclimation temperature (Fig. 1). 2. The extent to which the $$P_{O_2 }$$ of the water in the branchial chambers was increased by… CONTINUE READING
