Training Captive‐Bred or Translocated Animals to Avoid Predators
Abstract: Animal reintroductions and translocations are potentially important interventions to save species from extinction, but most are unsuccessful. Mortality due to predation is a principal causeExpand

Female preference for swords in Xiphophorus helleri reflects a bias for large apparent size.
Swordtail fish (Poeciliidae: genus Xiphophorus) are a paradigmatic case of sexual selection by sensory exploitation. Female preference for males with a conspicuous "sword" ornament is ancestral,Expand

On the meaning of alarm calls: functional reference in an avian vocal system
We demonstrate that chicken alarm calls are functionally referential, encoding sufficient information about the circumstances of production for conspecifics to respond appropriately, even in the absence of contextual cues potentially provided by the non-vocal behaviour of the sender. Expand

Insular tammar wallabies (Macropus eugenii) respond to visual but not acoustic cues from predators
We studied the way in which a population of tammar wallabies (Macropus eugenii), which have been isolated from mammalian predators since the last ice age, responded to the sight and sound ofExpand

Digital video playback and visual communication in lizards
Experimental analyses of dynamic visual signals have to overcome the technical obstacle of reproducing complex motor patterns such as those found in courtship and threat displays. Video playbackExpand

Nestling begging increases predation risk, regardless of spectral characteristics or avian mobbing
Models of parent--offspring conflict and nestling begging honesty often assume that signaling is associated with increased predation risk. However, little evidence exists that begging actuallyExpand

Introductory tail-flick of the Jacky dragon visual display: signal efficacy depends upon duration
A series of video playback experiments with a digitally animated tail, comparing the responses to digital video footage of a lizard tail-flick with those to a precisely matched 3-D animation, identify several variables that might mediate recognition. Expand

Familiar–unfamiliar discrimination based on visual cues in the Jacky dragon, Amphibolurus muricatus
Territorial animals typically have the ability to discriminate between familiar and unfamiliar conspecifics. This enables residents to minimize the costs of resource defence by matching the intensityExpand
