         Jersey. Evolution 35:101-123.

Contrary to earlier suggestions, local fire frequency plays a predominant role in setting local levels of serotiny in pitch pine. Although gene flow from the Pine Plains, an area of fire-swept pygmy forests with a high incidence of serotiny, is not important in setting the frequency of serotiny in other Barrens areas more than 3-5 km away, significant differentiation occurs between frequently burned upland sites and rarely burned lowland sites less than 100 m apart. Synergistic effects of fire, soil, and physiography on serotiny are emphasized. [From author's abstract]
