The biodiversity of these ecosystems is predicted by a model of immigration and extinction. For 10 points each:
[10e] Name these ecosystems whose theory of biogeography was developed by Robert MacArthur and E. O. Wilson. Charles Darwin observed extreme diversification of finches in this ecosystem.
ANSWER: islands [or isles or archipelagos; accept Galapagos Islands]
[10h] The rapid speciation observed in Darwin’s finches is described by this term. This evolutionary process is commonly studied in aquatic model organisms like cichlids and sticklebacks.
ANSWER: adaptive radiation
[10m] The theory of island biogeography is often used to study habitat fragmentation in these places. A namesake “heat island” effect describes how these ecosystems are warmer than their surroundings.
ANSWER: cities [or urban ecosystems or suburbs or suburban ecosystems]
