Abstract
Body temperatures, critical thermal maxima, tolerance to water loss, and rehydration rates were measured for T. diurnus in the rain forest on Mt. Glorious, south-eastern Queensland. Body temperatures ranged from 13.6 to 22.8'C (mean 1 8 . 4 i l .g°C) for adults and from 14.0 to 23.8"C (mean 19.852.4"C) for juveniles. Body temperatures were significantly higher in juveniles. The critical thermal maximum for T. diurnus was 31 . l i l . 2 " C and ranged from 28.4 to 33.7"C. Minimal activity temperatures appear to be reached in winter months. The mean lethal water loss for T. diurnus was 26.2 & 4.3 % of the original weight; this species shows less tolerance to desiccation than other Australian anurans that have been studied.https://doi.org/10.1071/ZO9710035
