Spatial patterns of cone serotiny
in Pinus banksiana in relation to fire disturbance.
Groom and Lamont (1997) proposed that strong serotiny in Hakea species was linked with significantly thicker and denser follicles than fruits of weakly serotinous species.
Whilst contentious, there is a convincing body of evidence that indicates granivory is a major driver of serotiny evolution.
Consequently, the correlation between thicker, denser follicles and strong serotiny may be explained by granivory pressure.

Cone serotiny of lodgepole pine near West Yellowstone, Montana.
In areas of high serotiny, lodgepole pine recruitment may continue through the first decade following fire, as ~10-15 yr of cones may be available to supply seeds (Johnson and Fryer 1989).
with low variability in percent serotiny observed across short distances ([is less than]1 km) and large distances ([is greater than]10 km) and high variability over intermediate distances (1-10 km).
Our sites spanned this range of variability, and mean serotiny was strongly related to location.
The prevalence of cone serotiny
in many peninsular stands of sand pine underscores the historical role of periodic crown fires in maintaining these populations.
