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
Despite Australia’s reputation for large, unique spiders, very little is known about the behaviour of many of these species. Wolf
Sexual selection requires intra-specific variation in the characteristics mediating mate choice. In species reliant on substrate-borne vibrational signalling (SBVS), differences
Australia’s dragon lizards (Family: Agamidae) employ dynamic visual signals in a variety of contexts but the signalling behaviour of this
