A Microcosm of Galápagos Biodiversity-Darwin's Finches in Galápagos
This program begins with spectacular scenery of the Galápagos islands, including a volcanic eruption. It introduces the idea of the archipelago being extremely dynamic geophysically and biologically, on both short and long time scales. It then illustrates the rich biodiversity of the archipelago with examples of plants, birds and insects from the small island of Daphne, and fish, sea-lions and sea birds in the marine environment nearby. The program shows how animals and plants living in both terrestrial and marine environments have to cope with a climate that fluctuates from extremes of hot and wet conditions to cool and dry ones.
