Geographical variation in head shape of a Neotropical group of toads: the role of physical environment and relatedness
(Wiley, 2017)In this study we review the morphological variation within the Rhinella crucifer species group using geometric morphometrics. We sampled 270 specimens from 78 localities comprising all genetic units delimited for the group. ...
