In one year, there were 18 males and 34 females. Over the following year, each female gave birth, of which 28 survived. Nine elephants died due to predators. A construction project cleared 50 acres of nearby forested land, causing 5 males and 19 females to immigrate into the experimental area. Competition for females increased, resulting in the emigration of 10 males to a new territory in search of mates.

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.
