Photopigments of dogs and foxes and their implications for canid vision
Abstract Electroretinogram (ERG) flicker photometry was used to examine the photopigment complements of representatives of four genera of Canid: domestic dog ( Canis familiaris ), Island gray fox ( Urocyon littoralis ), red fox ( Vulpes vulpes ), and Arctic fox ( Alopex lagopus). These four genera s...
