Estimating the age of #mediterranean #pines & their #cones is tricky, as they often produce more than 1 whorl per year!
Pic: #Pinus halepensis. From the bottom upwards: 🔵arrows: 1st whorl of a growing season;🔴&🟢arrows: 2nd & 3rd whorl of the same year. Note the #serotinous #cones in the left pic.

#Fire selects sexual #precocity in pines! https://onlinelibrary.wiley.com/doi/10.1111/oik.09373
Populations of #Pinus halepensis (a #serotinous #pines), subjected to higher frequency of crown fires (short fire interval) produce cones at younger ages than those pops that rarely #burnt
Being precocious in fireprone environments is adaptive because it increases the probability of having a significant seed bank for regeneration when the next fire arrives
