Varying degrees of serotiny are expressed in the genus Hakea (Groom and Lamont 1997), with some species believed to recruit only after fire as obligate reseeders.
eriantha suggesting that, whilst both species are serotinous, the degree of serotiny varies substantially between the two species occurring in very similar vegetation types.
However, previous studies have not addressed successional questions related to stand serotiny and canopy seed viability and germination following beetle-induced tree mortality.

Serotiny has evolved in many species under the selective pressure of fires (Gauthier et al.

Seedling density was positively correlated with number of prefire serotinous individuals at Cougar Creek (Table 5), which had the highest mean serotiny level (65%) among the geographic locations, but the correlation was not significant at Fern Cascades or Yellowstone Lake (Table 5), where mean serotiny and numbers of seedlings were much lower.
Some seeds also survived in most crown fires, especially where serotiny was high, as pine seedlings were found in areas even [is greater than]200 m from the nearest severe-surface burn.

The principal basis for varietal separation was a purported contrast in expression of cone serotiny (Little and Dorman, 1952; Ward, 1963); however, recent studies have reported considerable variability in the degree of cone serotiny, especially within Ocala sand pine.
