Reaction To Competition
Pin oak is classed as intolerant of shade. It is less tolerant than elm, boxelder (Acer negundo), sweetgum, hackberry (Celtis occidentalis), and ash, but is more tolerant than eastern cottonwood and black willow. Pin oak usually grows in even-aged stands of dominant and codominant trees. Intermediate and suppressed trees in such stands usually die within a few years of being overtopped. Single pin oaks in mixed stands usually are dominants. Pin oak is considered a subclimax species. It persists on heavy, wet soils because it produces an abundance of acorns which, if released, grow faster on these sites than most of its competitors.

Famous quotes containing the words reaction to, reaction and/or competition:
“In a land which is fully settled, most men must accept their local environment or try to change it by political means; only the exceptionally gifted or adventurous can leave to seek his fortune elsewhere. In America, on the other hand, to move on and make a fresh start somewhere else is still the normal reaction to dissatisfaction and failure.”
—W.H. (Wystan Hugh)
“Children, randomly at first, hit upon something sooner or later that is their mother’s and/or father’s Achilles’ heel, a kind of behavior that especially upsets, offends, irritates or embarrasses them. One parent dislikes name-calling, another teasing...another bathroom jokes. For the parents, this behavior my have ties back to their childhood, many have been something not allowed, forbidden, and when it appears in the child, it causes high-voltage reaction in the parent.”
—Ellen Galinsky (20th century)
“Wearing overalls on weekdays, painting somebody else’s house to earn money? You’re working class. Wearing overalls at weekends, painting your own house to save money? You’re middle class.”
