| Abstract | Relatively few studies have used experimental manipulations to investigate the mechanics of vocal production in frogs and toads, even though many frogs produce complex signals with multiple components and/or nonlinearities. Modelling approaches can add to empirical studies by illuminating how various components of the vocal system interact to produce communication signals. In this study, we use bond graphs, a lumped-element modelling technique, to explore how the combination of active modulation of vocal production and the passive dynamics of a unique laryngeal structure result in the complex calls produced by males in an anuran model system. The tungara frog (Physalaemus (= Engystomops) pustulosus) produces advertisement calls with a ‘whine’ and a facultative ‘chuck’. Whines are amplitude and frequency modulated. The chuck is characterized by its spectral complexity and appears to contain a period doubling bifurcation resulting in subharmonics. In our model, we focus on how a fibrous mass attache... |
