| Abstract |
Groups of tadpoles of Limnodynastes peronii (Anura, Myobatrachidae) were kept at two temperatures (15 degrees and 25 degrees Celsius) for 45-105 days. In a thermal gradient (6-36
degrees C), initial thermal preferenda were significantly different in 15 degrees and 25 degrees C history groups, approximately 13 degrees C and 21 degrees C respectively. However, after 2.5
hours, these initial differences were no longer seen and the final thermal preferendum was approximately 18 degrees C regardless of previous thermal history. Considering these results and the lack
of metabolic acclimation reported elsewhere, these tadpoles can be seen as ecotherms whose thermal strategies are behavioural rather than physiological or biochemical. The rapid loss of acclimation
of preferred temperature is discussed in relation to Fry's 'final preferendum' paradigm.
