Galapagos Finch Population and Seed Counts
Assessment
Daphne Major, one of the Galapogos Islands approximately 1000km west of Ecuador, is home to ground finches (Geospiza fortis) and many species of seed-bearing plants. Two species of plants, Portulaca and Tribulus, produce seeds that the finches eat. You are part of a team that is investigating the relationship between the size of ground finch population on Daphne Major, and the density of Portulaca and Tribulus seeds present on this isolated island.
