Predator-specific camouflage in chameleons.
A crucial problem for most animals is how to deal with multiple types of predator, which differ in their sensory capabilities and methods of prey detection. For animals capable of rapid colour change, one potential strategy is to change their appearance in relation to the threat posed by different predators. Here, we show that the dwarf chameleon, Bradypodion taeniabronchum, exhibits different ...
متن کاملPredator and prey views of spider camouflage.
Crab-spiders (Thomisus onustus) positioned for hunting on flowers disguise themselves by assuming the same colour as the flower, a strategy that is assumed to fool both bird predators and insect prey. But although this mimicry is obvious to the human observer, it has never been examined with respect to different visual systems. Here we show that when female crab-spiders mimic different flower s...
متن کاملSpecific color sensitivities of prey and predator explain camouflage in different visual systems
In situations of aggressive mimicry, predators adapt their color to that of the substrate on which they sit for hunting, a behavior that is presumed to hide them from prey as well as from their own predators. Females of few crab-spider species encounter such situations when lying on flowers to ambush pollinators. To evaluate the efficiency of spider camouflage on flowers, we measured by spectro...
متن کاملDetecting Digital Chameleons 1 Detecting Digital Chameleons
Conversations are characterized by an interactional synchrony between verbal and nonverbal behaviors (Kendon, 1970). A subset of these contingent conversational behaviors is direct mimicry. During face to face interaction, people who mimic the verbal (Giles, Coupland, & Coupland, 1991) and nonverbal behaviors (Chartrand & Bargh, 1999) gain social advantage. Most research examining mimicry behav...
متن کاملBackground evolution in camouflage systems: a predator-prey/pollinator-flower game.
A common predator or anti-predator strategy involves camouflage based on background matching. In some systems, the background is an organism whose fitness is affected by the predator-prey interaction. In these cases, the phenotype of the background species may evolve to affect the degree of background matching in the predator-prey interaction. For example, some flower species (the background) a...
