Sounding Off: Relationships between Call Properties, Body Size, Phylogeny, and Laryngotracheal Form of Geckos

Gekkotan lizards are the most vocal of all squamates and a majority of species (exclusive of eublepharids and most diurnal geckos) are capable of producing both distress calls and more complex advertisement calls, the latter being typically restricted to males. Although the vocal characteristics of some individual species are known, this study presents the first effort to identify general patterns in vocalization and laryngotracheal morphology...
