Biology · Ecology and Biogeography
The taxon cycle predicts progressive ecological and evolutionary changes in insular biotas based on fundamental capacities to evolve, immigrate, and persist. The table below lists species types (Column X) and traits (Column Y). Column X P. c Q. d R. e S. b Column Y i. Ecologically naive species, and endemics near the end of the taxon cycle (e.g., dwarfed elephants) ii. An unlikely type, because the ability to evolve on isolated islands requires relatively long persistence iii. Limited dispersal abilities; unlikely to inhabit isolated oceanic islands iv. Supertramps, powerful dispersers such as microsnails, ferns, and rafting rodents Which one of the following options represents all correct matches between Column X and Column Y?
