What is the role of intraspecific competition (competition between members of the same species) in Ecological Speciation? Intraspecific competition leads to character displacement. Intraspecific competition leads to a decrease in effective population size. Intraspecific competition maintains isolation between new species. Intraspecific competition leads to stabilizing selection and eventual divergence.
