Ambient temperature and air pressure modulate hormones and behaviour in Greylag geese (Anser anser) and Northern bald ibis (Geronticus eremita).

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 le...
