Variation in thermal plasticity of larval morphology among crested newt species and their reciprocal hybrids (Salamandridae: Triturus).

Abstract excerpt

Phenotypic plasticity is assumed to play crucial role under climate change, as it enables organisms to cope with rapidly increasing environmental pressures. We investigated the effect of water temperature on head and tail morphology in larvae of two crested newt species (Triturus ivanbureschi and T. macedonicus) and their reciprocal F1 hybrids. Larvae were raised under experimental conditions at 19 °C and, from...
