QUESTION 1 * RsQ_013From Exercise 1, question 6.2, what does the diversity index when you stopped the simulation indicate about this system?
 * | * | * The diversity index was relatively low, and so there were a wide variety of species represented. | * | * | * The diversity index was relatively high, and so there were a wide variety of species represented. | * | * | * The diversity index was relatively high, and so there were few species represented. | * | * | * The diversity index was relatively low, and so there were few species represented. | *

QUESTION 2 * RsQ_011From Exercise 1, question 9: What happened to the diversity value when you held the average # of fires/year constant at 0.2, but varied the chance of spread from 0.1 to 0.95?
 * | * | * The diversity value increased consistently as you went from a chance of spread of 0.1 to a value of 0.95. | * | * | * The diversity value decreased consistently as you went from a chance of spread of 0.1 to a value of 0.95. * | * | * | * The diversity value did not change significantly. | * | * | * The diversity value increased from 0.1 to about 0.5, and then decreased as the chance of spread reached 0.95. * | * | * | * The diversity value decreased from 0.1 to about 0.5, and then increased as the chance of spread reached 0.95. * | *
