Description
  • Despite many studies demonstrating the effect of acclimation on behavioral or physiological traits, considerable debate still exists about the evolutionary significance of this phenomenon. One of the unresolved issues is whether acclimation to warmer temperature is beneficial at treatment or at more extreme test temperatures. To answer this question we assessed the effect of thermal acclimation on preferred body temperatures (Tps), maximum swimming and running speed, and critical thermal maximum (CTmax) in the Danube crested newt (Triturus dobrogicus). Tps were higher in newts kept at 15°C than in those kept at 25°C. The maximum swimming speed did not acclimate. The maximum running speed at 30-33°C was substantially higher in newts kept at 25°C than in those kept at 15°C. CTmax increased with the treatment temperature. Hence, we conclude that the acclimation response to warm temperature is beneficial not at treatment but at more extreme temperatures in newts.

  • Ačkoliv mnoho studií prokázalo vliv aklimace na behaviorální a fyziologické znaky, evoluční význam tohoto jevu je stale diskutabilní. Jednou z nevyřešených otázek je, zda aklimace na vyšší teplotu je prospěšná při aklimační teplotě nebo při extrémnějších experimentálních teplotách. K zodpovězení této otázky jsme posuzovali vliv aklimace na preferované teploty těla (Tps), maximální rychlost plavání a běhu a kritické teplotní maximum (CTmax) u čolka podunajského (Triturus dobrogicus). Tps byly vyšší u čolků držených v 15 °C než u těch držených v 25°C. Maximální rychlost plavání neaklimovala. Maximální rychlost běhu při 30-33 °C byla podstatně vyšší u čolků držených při 25 °C než u těch držených při 15 °C. CTmax se zvyšovalo s aklimační teplotou. Z toho usuzujeme že u čolků je aklimační odpověď na vyšší teplotu prospěšná ne při aklimační, ale při extrémnějších teplotách. (cs)
