Models of signal evolution predict that the threat posed by eavesdropping predators will influence the evolution of signal structure and
Studies have shown that numerous species eavesdrop on the calls of heterospecifics to gain information about predator presence. Responding to
In this project, we aim to examine the multimodal communication of an Australian anuran species, Litoria fallax (the eastern sedge
Many vertebrates use vocalizations to communicate about the presence of predators, and some encode information about predator type or behaviour.
Signaling species occurring in sympatry areoften exposed to similar environmental constraints, so similar adaptations to enhance signal efficacy are expected.
For animals to communicate effectively, signals are required to be successfully detected by an intended receiver across the extent of
Visual signalling is used during inter and intra specific interactions, and has evolved toward complex, diverse and highly species-specific displays.
The environment in which animal signals are generated has the potential to affect transmission and reliable detection by receivers. To
Habitat characteristics influence the efficacy of animal communication, and population differences insignal structure due to habitat variation are well known
Competition between animals for limited resources often involves signaling to establish ownership ordominance. In some species, the defended resource relates
