Interesting stuff. One minor detail: the breakdown of chlorophyll does not "allow red anthocyanin pigments to become visible" in deciduous tree leaves: they are formed at about the same time as the breakdown. (If they were present all along, leaves would look dark brown, like a copper beech).

Has there been any consideration of collecting some of the best of these into a coffee table type book? Or a e-reader format. Seems like it would sell.
