Animal Behavior: Signaling and Communication
Problems
Problem :
Many animals, when presented with a conflict, lay back their ears to protect them in case of a fight. In some species this behavior has become a signal of aggression. What is the process by which this happens?
Problem :
A given habitat supports two types of poisonous frogs. In one species of frog, bright coloration begins to evolve as a signal to predators that the frog is poisonous. Soon the other species of frog also begins to evolve bright coloration. What type of mimicry is this?
Problem :
In the case of two species of poisonous frogs that share the same habitat, what is the advantage of both developing the same danger signal to predators?
Problem :
Skunks signal danger to other species by the broad white stripe down their backs. If another, harmless species were to develop a similar white stripe, what type of mimicry would this be?
