As documented by peter and rosemary grant, the population of the medium ground finch on the tiny island of Daphne major in the Galápagos archipelago responded how to changes in food resources associated with climate changes:

#Unit 10. Ecological Principles
  1. During the drought of 1975-1978, the population decreased
  2. The average beak size of surviving individuals, and their progeny, increased significantly between 1976 and 1978
  3. During the exceedingly wet El niño year of 1983, birds with smaller beaks handled the abundant smaller seeds more efficiently and the average beak size of the population returned to a lower value
  4. All of the above
