“…However, we did not found any association between Tb and body mass or size, which suggests that P. thaul cannot use its body characteristics as a mechanism for thermoregulation , probably because of its small body size. In the laboratory, the body temperature of P. thaul was higher during the active than inactive hours, and showed a close relation with the pattern of the substrate and air temperature, as in other species (Lambrinos & Kleier 2003). Our study was performed during mid-winter; a condition that favours thermoconformism due to the lower availability of thermal resources (Huey 1982;Labra et al 2008).…”

“…Pearson & Bradford 1976;Labra et al 2008), and these restrictions for thermoregulation make most amphibians thermoconformists, i.e. their body temperature strongly correlates with the air and/or substrate temperature (Lambrinos & Kleier 2003). Recently it was claimed that one important way in which ectotherms can reduce the effect of climate change is by behavioural thermoregulation (e.g.…”

“…Por ejemplo, en anuros se ha reportado la heliotermia en animales que tienen la capacidad de captar calor a través de la radiación solar, como Bufo boreas y Bufo spinulosus (Lillywhite et al, 1973;Lambrinos & Kleier, 2003), y la tigmotermia, en animales que captan el calor por conducción, como Leptodactylus ocellatus, Pleurodema thaul (Sanabria et al, 2003;Iturra-Cid et al, 2014) y algunas especies de Bufonidae y Leptodactylidae que termorregulan en sustratos secos y húmedos, de acuerdo con experimentos realizados en laboratorio (Tracy et al, 1993;Sanabria et al, 2005), así como durante cambios estacionales en campo (Sanabria et al, 2011;Iturra-Cid et al, 2014).…”

“…Esto hace que la mayoría tengan tendencias termoconformadoras, en donde la temperatura corporal está relacionada con la temperatura del sustrato o del aire (Lambrinos & Kleier, 2003;Iturra-Cid et al, 2014), y particularmente en el caso de las salamandras, las necesidades por mantener niveles hídricos adecuados las confina a ambientes húmedos con poca diversidad térmica (Feder, 1982), por lo que la termorregulación comportamental es poco común en la mayoría de ellas .…”

“…This maintenance of a larger thermal gradient between the skin surface and T A allows the tortoise to forage for longer periods under direct solar radiation (Coe, 2004). Some species of toads living at high altitudes are more active on sunny days, raising their T B by 20° or more in some cases (Lambrinos & Kleier, 2003). Heat gain using solar radiation also aids in digestion and increases growth rates of toads and other anurans at both extreme and moderate elevations.…”
