Ecological Aspects
The fruit has a pleasant and mild odor, but is inedible for the most part. Although it is not strongly poisonous, eating it may cause vomiting. However, the seeds of the fruit are edible. The fruit is sometimes torn apart by squirrels to get at the seeds, but few other native animals make use of it as a food source. This is unusual, as most large fleshy fruit serves the function of seed dispersal by means of its consumption by large animals. One recent hypothesis is that the Osage-orange fruit was eaten by a giant ground sloth that became extinct shortly after the first human settlement of North America. Other extinct Pleistocene megafauna, such as the mammoth, mastodon and gomphothere, may have fed on the fruit and aided in seed dispersal. An equine species that went extinct at the same time also has been suggested as the plant's original dispersal agent because modern horses and other livestock will sometimes eat the fruit.

Famous quotes containing the words ecological and/or aspects:
“The hatred of the youth culture for adult society is not a disinterested judgment but a terror-ridden refusal to be hooked into the, if you will, ecological chain of breathing, growing, and dying. It is the demand, in other words, to remain children.”
—Midge Decter (b. 1927)
“That anger can be expressed through words and non-destructive activities; that promises are intended to be kept; that cleanliness and good eating habits are aspects of self-esteem; that compassion is an attribute to be prized—all these lessons are ones children can learn far more readily through the living example of their parents than they ever can through formal instruction.”
—Fred Rogers (20th century)
