The probe was successfully deployed in four species of penguins and measured pH for periods of uup to 10 days under fluctuating pressuure conditions. The resolution of pH was better than 0.1 pH units, and the absolute accuracy was on average better than 0.25 pH units for deployment in Pygoscelis penguins and better than 0.1 pH units in Spheniscus penguins. Stomach pH in chick-rearing penguins was highly flexible, with values ranging from below pH 2 to virtually neutral, allowing the birds to adjust the rate of digestion to the prevailing demands |
