Background Urban development results in habitat destruction, affecting populations of amphibians, the most fragile
group of vertebrates. With changes in the environment, these animals become more exposed to light and predators.
To enhance their chances of survival, they display plasticity of body coloration. Aside from adaptive benefits,
animals exhibiting background matching meet the energetic costs and restrictions of changing body tones. To study
the physiological consequences of Hyla arborea tadpole adaptation to background color, we followed oxidative stress
parameters after rearing larvae on a constant background (black/white) and after changing the background color.
Results Larvae cultivated for 20 days on constant substrate color exhibited differences in body coloration but without
differences in lipid peroxidation (LPO) concentration between dark and pale individuals, suggesting that coloration
investment during this period did not induce higher oxidative damage in darker tadpoles. Prolonged exposure
of larvae (37 days) to a dark habitat increased antioxidative system defense and LPO concentrations, compared to
animals reared permanently in the white surroundings. The positive correlation of oxidative damage with color
intensity of individuals points to the physiological consequences of higher investment in the number of pigment cells
necessary for dark pigmentation. In individuals faced with non-matching background and change in body coloration,
defense system declined and LPO occurred relative to individuals cultivated in white habitat.
Conclusion Here, we have pointed to consequences related to background matching and stress that amphibians
experienced during chromatic adaptations. Background color change causes a complex physiological response
affecting the antioxidative defense parameters. This investigation elucidates the accompanying cost of amphibiansʼ
adjustment to an altered environment.
