Ontogenetic switch between alternative antipredatory strategies in the leopard gecko (Eublepharis macularius): defensive threat versus escape

Popis výsledku v původním jazyce

Ontogenetic changes in antipredator behavior optimize survival of growing animals. Leopard geckos (Eublepharis macularius) respond to a simulated predator either by postural and vocal threats, sometimes followed by biting, or alternatively by a rapid escape. The former "confrontational" and the latter "avoidance" behavior rarely occurs in a sequence; in fact, they represent mutually exclusive defensive strategies. We examined 552 individuals of a leopard gecko (E. macularius) of various ages, from hatching up to adulthood (31 months). Each experimental animal was exposed to a sequence of five "water-spraying" and ten "stick" (stick poking on base of the tail) stimuli, and the emitted behavior was recorded. We analyzed the effects of age, body size, body condition, adult-juvenile coloration, and sex on observed behavioral traits. The results showed that in the case of water-spraying stimulus, the usage of deterrent vocalization or escape tactic was affected by age and condition. In addi
