Taxon cycle
Webthe taxon cycle. Theoretically, the most desirable test of the taxon cycle would use a complete computational model that explicitly inte-grates all ecological and evolutionary processes proposed in Wilson's verbal model of the taxon cycle, including speciation, extinction, dis-persal, competition, biotic innovations and interactions among these
