Suppose You Are Studying the Effect of Predation on Levels

question 67

Essay

Suppose you are studying the effect of predation on levels of cortisol in a species of mouse in the lab. You set up an experiment in which you house some mice in cages with photographs of rabbits on the walls of their cages; others are housed with photographs of flowers on the walls of their cages; while others are housed with photographs of hawks. The cortisol level in mice blood plasma (nmol/L) after exposure to the photographs measures 190 for rabbits, 475 for hawks, and 185 for flowers. Why did you expose the mice to three different types of photographs? What type of relationship would an individual mouse have with the different plant/animal species pictured? Why did the hawk photograph result in the highest levels of cortisol?
