Northern Two-lined Salamander, Eurycea bislineata, communal oviposition site, Algonquin Provincial Park, OntarioRésumé
While surveying a stream for amphibians in Algonquin Provincial Park, Ontario, Canada, I discovered a clutch of Two-lined Salamander (Eurycea bislineata) eggs on the underside of a partially submerged rock. I counted 165 eggs and measured them using ImageJ from a digital photograph. The quantity of eggs is far greater than any known clutch size for this species, and it was likely deposited by more than one female. This is the first report of communal oviposition in this species in Canada.Téléchargements
