Answer one of the following using examples from material covered for this exam (10 points)

  1. Certain life history characteristics (characteristics of the species biology, not human caused) make certain species more susceptible to extinction. What are the two most important features of their life history that make them susceptible? Give examples of strategies that could be used to help preserve TWO mammals from different orders facing DIFFERENT natural problems.
  2. Give three examples of follivores from three different families from at least two different orders. What characteristics do they have in common? How do they differ?
