Description
Abstract. -- The relationships of body mass and developmental stage to acid tolerance were examined in tadpoles of three species of anurans from central Texas: Bufo woodhousei, Bufo valliceps, and Gastrophryne olivacea. Significant differences in survival time at low pH occurred among all three species (survival time of Bufo valliceps Bufo woodhousei Gastrophryne olivacea). Body mass and developmental stage were significantly correlated, and their relationship to survival time was complex and species specific. Multiple regression analysis indicated that for Bufo woodhousei, mass was positively associated with survival time; there was no effect of developmental stage independent of its correlation with mass. For Bufo valliceps, mass was positively associated with survival time, whereas developmental stage was negatively associated with survival time. Neither mass nor developmental stage were significantly associated with survival time in Gastrophryne olivacea. **********
