Why do pine cones open and release seeds after a fire?

Pine cones, particularly those from serotinous species, open and release seeds after a fire as a survival strategy. The heat from the fire triggers the cones to open, allowing seeds to be dispersed in a nutrient-rich, cleared environment with less competition. This adaptation enhances the chances of seed germination and growth in the aftermath of a fire, facilitating the regeneration of pine forests. This process is essential for the life cycle of certain pine species, ensuring their continued propagation.
