Diet and Decline
About 70% of the Texas horned lizard's diet is made up of harvester ants, though they supplement these with termites, beetles, and grasshoppers. In recent years, the Texas horned lizard has declined by about 30% of its range, though there is some indication it may be making a comeback. The decline is usually blamed on overuse of pesticides and the spread of nonnative, but highly aggressive and fiercely territorial, red imported fire ants. Both eradicate harvester ant colonies, destroying the horned lizard's principal source of food. The Texas horned lizard is now a protected species, and it is illegal to take, possess, transport or sell them without a special permit.

Famous quotes containing the words diet and/or decline:
“I learned from my two years’ experience that it would cost incredibly little trouble to obtain one’s necessary food, even in this latitude; that a man may use as simple a diet as the animals, and yet retain health and strength.... Yet men have come to such a pass that they frequently starve, not for want of necessaries, but for want of luxuries.”
—Henry David Thoreau (1817–1862)
“Families suffered badly under industrialization, but they survived, and the lives of men, women, and children improved. Children, once marginal and exploited figures, have moved to a position of greater protection and respect,... The historic decline in the overall death rates for children is an astonishing social fact, notwithstanding the disgraceful infant mortality figures for the poor and minorities. Like the decline in death from childbirth for women, this is a stunning achievement.”
—Joseph Featherstone (20th century)
