Sex determination of scopoli's shearwater (calonectris diomedea) juveniles: A combined molecular and morphometric approach
Karris, Georgios; Thanou, E.; Xirouchakis, Stavros M.; Voulgaris, M. -D; Fraguedakis-Tsolis, S.; Sfenthourakis, Spyros; Giokas, Sinos (2013)The absence of juvenile sexual dimorphism in birds often impedes sex determination using external morphology. We examined sex ratio variation in Scopoli's Shearwater (Calonectris diomedea) fledglings (n = 135) on a Strofades ...
