摘要:
Several populations and life history stages of the tiger salamander, Ambystoma tigrinum, from elevations above 2890 m were studied in the field and laboratory. All groups selected the warmest water available in the ponds regardless of the actual temperature which rarely exceeded 25° C in the shallows. At night they moved into deeper water as the shallows cooled. In the laboratory aquatic thermal gradient, first year and older larvae tended to choose warmer temperatures (x̄ = 23.0°-25.5° C) than metamorphosed adults (x̄ = 18.4°-23.7° C). Furthermore, larvae and neotenic adults exhibited a narrower thermal preferendum than did metamorphosed adults. Behavioral thermoregulation may be particularly important in high altitude areas where the active growing season is short.
