Vibrations generated by road traffic are considered to be a form of physical environmental pollution. Nonetheless, the effect of this disturbance in natural habitats, and in particular on the aquatic stage of amphibians, received very little attention from the scientific community. This study aims to assess the direct effect of mechanical waves and the consequent water turbidity on the aquatic larval stage of Rana temporaria by exposing an experimental group to laboratory-induced vibrations and comparison with a non-exposed control group. Our results show that this kind of pollution had no significant effect on the development rate, the length of the larval period, and the mortality of the larvae. However, we identified a significant effect on the size of animals, both during the larval period, and at metamorphosis. This result raises concern about the long-term risks to the amphibian population exposed to this type of low-profile pollution.
Keywords: development, growth, metamorphosis, amphibian performance, traffic-related pollution
