Effects of environmental pH and temperature on embryonic survival capacity and metabolic rates in the smallmouth salamander, Ambystoma texanum
Although the deleterious effects of acid precipitation on forest ecosystems and fisheries have been documented, relatively little information is available on the effects of environmental pH in combination with temperature on the survival capacity and/or physiology of amphibians. Increased acidity resulting from acid precipitation common to the northwestern United States, can lead to increased mortality in the spotted salamander, Ambystoma maculatum. In view of the potentially significant deleterious effects of stressful pH conditions on amphibian survivorship and the relative paucity of data on this subject, the present study was conducted in order to ascertain the combined effects of temperature and pH on embryonic metabolic rates and survival capacity in the smallmouth salamander, Ambystoma texanum Mathes. No previous data on these parameters are available for this species.
