Serotiny, a process by which certain conifers create fertilized yet sealed cones that must be heated to open, was discovered by plant ecologists, and this led to an understanding that the forests that grew on 80 percent of the Yellowstone landscape do not do so in spite of fire, they exist as we see them because of fire.
Serotiny has evolved in many species under the selective pressure of fires (Gauthier et al.
