Abstract

AbstractThe relations between environmental variables (minimum temperature, daily thermal oscillation, rainfall and atmospheric pressure) and the onset of the spawning period of the common frog (Rana temporaria) in the Atlantic region of the Basque Country (Northern Spain) is analyzed. The onset of the spawning period is coincident with a change in temperature occurring four days prior to spawning. Atmospheric pressure looks not as a related factor, whereas the influence of rain seems to become apparent over a longer period of time.
