Question

13. Hawaiian Island fruit fly biogeography is a little more complex than for silverswords. Their deduced colonization and speciation events are summarized in Figure 6.10. What percentage of all colonization events occurred between neighboring island groups?

Answer 1

From fog. 6.10, the information we can derive is the total no. of colonization events that happened across all islands and the number of colonization events that occurred in between neighboring islands.

From the figure,

Total no. of colonization events = 45

Total no. of colonization events that occurred between neighboring islands = 38

Thus, % of colonization events to occur between neighboring islands = 38/45 * 100 = 84.44%
