We are pleased to report that Snow’s paper – the Virtual Lens Project method paper – was just published in
Cryptic walking of chameleons
Chameleons are known to spontaneously perform jerky movements when walking. This jaggered walking behaviour has been assumed to be mimicking
Motion signals and lizard muscle
The Jacky lizard (Amphibolurus muricatus) responds to greater plant motion noise by extending the duration of introductory tail flicking, which
Motion Signalling & Predators
Models of signal evolution predict that the threat posed by eavesdropping predators will influence the evolution of signal structure and
Lizards choose perches non randomly
Effective visual crypsis requires that animals behave in a manner consistent with their camouflage. Individuals who employ background-matching strategies are
Zebra finches and heterospecific alarm calls
Studies have shown that numerous species eavesdrop on the calls of heterospecifics to gain information about predator presence. Responding to
Zebra finches don’t alarm call
Many vertebrates use vocalizations to communicate about the presence of predators, and some encode information about predator type or behaviour.
Interspecific variation in motion displays
Signaling species occurring in sympatry areoften exposed to similar environmental constraints, so similar adaptations to enhance signal efficacy are expected.
