As a hypothetical example, imagine that you were studying a population of Eastern Collared-Lizards (Crotaphytus collaris). The lizards laid 2000 eggs, of which 1000 were eaten by raccoons and skunks. Eight hundred of the surviving juveniles were eaten by foxes and cats. One hundred and eighty of the young adults died during their first hibernation period. What is the indispensable mortality for each stage? If you want to increase the numbers of reproducing adults, which stage should you focus on?

Animal Behavior

Animal behavior can be defined as all the things that animals do. In response to a stimulus, an animal performs a certain fixed action pattern, or FAP, of behavior. This response occurs to make the animal more adaptable to change. So, behavior is generally a stimulus-oriented response. A behavior is an expression of the capabilities of the nervous system. A stimulus is determined by the environment, while the nervous system determines a response.
