title: Temperature dependence of visual fusion frequency in Rana lessonae cam., Bufo bufo L. and Bombina bombina (L.) (Amphibia).
abstract: The electroretinogram (ERG) was used to measure the flicker-fusion frequencies of Rana lessonae, Bufo bufo and Bombina bombina over the temperature range 5-25°C. In all three species the fusion frequency increased with increasing temperature. In the intermediate range of temperatures, the fusion frequencies of Rana lessonae and Bombina bombina doubled when the temperature was raised by 10°C.
