... • This graph shows the decline in the population of one of Darwin's finches on Daphne Major, a tiny (100-acre) member of the Galapagos Islands. The decline (from 1400 to 200 individuals) occurred because of a severe drought that reduced the quantity of seeds on which this species feeds. The drought ...

Example: Interspecific Competition • Two species of barnacles on rocky coasts often compete for space. • The smaller species (Chthamalus) is unable to compete as well as the larger species (Balanus). • However, Chthamalus can survive drying better than Balanus, so it can live higher up on the rocks ...
