Pelodytes punctatus est une espèce dont les biotopes de reproduction sont localisés en plaine principalement (90% des cas). De nouvelles données sur la phénologie de la reproduction ainsi que sur le type de milieu ont été collectées durant 6 ans sur 4 régions comprenant plus de 35 sites. La période de ponte principale survient au printemps mais on...

... When the larvae begin to hatch, the male toads sit in water and the larvae are released. Therefore, Alytes dickhilleni does not need a particular type of substrate or vegetation for spawning in contrast to other species of anuran amphibian such as Pelodytes punctatus (Guyétant et al., 1999) or Hyla meridionalis (Salvador and García-París, 2001). Hence, the detected independence of this species with respect to the microhabitat environmental variables considered suggests that the presence of water in a given water body for a long period of time would be the only condition for reproduction of Alytes dickhilleni, so that it could finish its larval phase, as was shown by Salvador and García-París (2001). ...
... In the Iberian Peninsula, it is restricted to the northeast, including eastern Catalonia (Martínez-Rica 1983;Barbadillo 2002b), where it reaches its maximum altitude in the Pyrenees (2,000 m; Borrás & Polls 1987;Guix et al. 2009). In France and Italy, P. punctatus inhabits plains (Guyétant et al. 1999;Salvidio et al. 2004;Pottier 2008), is absent from most of the French Pyrenees (Boulenger, 1897;Guyétant & Geniez 2013) and only exceeds elevations of 1,000 m in the Massif Central and in the Alpes Maritimes (Salvidio & Bologna 2007). The fossil record suggests an ancient presence of P. punctatus at the east of its present distribution (Blain & Bailón 2003;Delfino 2004). ...
