question 108

Multiple Choice

Three species of grasshoppers are found in a transect: 10 of species A, 15 of species B, and 25 of species C. What is the Shannon diversity index of this transect? (Note: * = times, and ln (x) is the natural logarithm of x.)

• A) [0.1 * ln (0.1)] + [0.15 * ln (0.15)] + [0.25 * ln (0.25)]
• B) [10 * ln (10)] + [15 * ln (15)] + [25 * ln (25)]
• C) The negative of { [10 * ln (10)] + [15 * ln (15)] + [25 * ln (25)]}
• D) The negative of { [0.1 * ln (0.1)] + [0.15 * ln (0.15)] + [0.25 * ln (0.25)]}
• E) The negative of { [0.2 * ln (0.2)] + [0.3 * ln (0.3)] + [0.5 * ln (0.5)]
