Journal ArticleDOI
Essay on Contemporary Issues in Ethology: Variation among Mammalian Alarm Call Systems and the Problem of Meaning in Animal Signals
TL;DR: Comparisons of the physical, behavioral and habitat characteristics of primates and ground-dwelling sciurid rodents suggest that incompatibility of the escape responses required to avoid different classes of predators may have been an important factor in the evolution of functionally referential alarm calls.
Journal ArticleDOI
What is Communicated in the Antipredator Calls of Lemurs: Evidence from Playback Experiments with Ringtailed and Ruffed Lemurs
TL;DR: In this paper, two hypotheses of signal specificity in antipredator calls (referential signalling and response urgency) are discussed in light of prior research on ground squirrels and vervet monkeys.
Journal ArticleDOI
Effects of apparent size and speed on the response of chickens, Gallus gallus, to computer-generated simulations of aerial predators
TL;DR: In this paper, computer-generated animations of raptor-shaped images were presented on an overhead video monitor to explore the stimulus characteristics necessary for eliciting both aerial alarm calls and non-vocal anti-predator behaviour (e.g. crouching and visual fixation).
Journal ArticleDOI
Predation cost of conspicuous male coloration in collared lizards (Crotaphytus collaris) : An experimental test using clay-covered model lizards
TL;DR: A survival cost of conspicuous coloration in collared lizards is suggested, and the importance of considering the visual environment as well as differences among populations when examining the influence of predation on the evolution of animal color patterns is reiterated.
Journal ArticleDOI
Phylogeny of the Lemuridae Revisited: Evidence from Communication Signals
TL;DR: Results of the present study suggest that shared Varecia-indrid character states may be symplesiomorphic retentions in the Indridae, and that Vrecia could be phyletically more primitive than either the indrids or lemurids.
