The result was remarkable a virtual Mima field whose hillocks had the sizes and pattern of distribution of the real thing.This would explain Mima fields just in North America, of course, since that is the only continent where pocket gophers live.
Gophers live for merely a few years, but a mound can take half a millennium to form.
He believes the builders, at least in America, are pocket gophers.This idea is not new, for Mima mounds often host pocket gophers.
It seems from this that gophers shove the spoil their digging creates in an uphill direction slightly more often than in a downhill one, though why they do so is unclear.To find out if that behaviour might be enough to create mounds, Dr Gabet built a computer model which started with a landscape that varied in height just a little, and randomly.
Gophers move west, while simultaneously becoming physically smaller.His work in a place called Porcupine Cave in Colorado, shows that cheetahs, camels, horses and peccaries were present 800,000 years ago, yet none of these species survives there today.

Past calls have resulted in the apprehension of juvenile muskrats, squirrels and northern pocket gophers.
Coyotes, foxes, and lynx, together with the gophers (Richardson's ground squirrel), rabbits, and other creatures they prey on, are abundant.
White-tailed deer, foxes, cottontail rabbits, skunks, woodchucks, squirrels, chipmunks, and gophers are common in all areas.
The wide variety of rodents includes gophers, hamsters, jerboas, and field mice.
Some vertebrates are also in the megafauna category; these include all sorts of burrowing animals, such as snakes, lizards, gophers, badgers, rabbits, hares, mice, and moles.
