The distributions of animals are influenced by geographic, vegetational, and altitudinal factors.
The Wilson snipe migrates here to but little extent, and these migrations are altitudinal rather than latitudinal.
If it were applied to present altitudinal data, it would place the computational flight ceiling somewhere below 4000 feet.
In reality, the assumption is sound only if the altitudinal distribution of migrants is uniform.
A particularly interesting phase of it lies in the matter of altitudinal distribution of the various species.
The Park has an altitudinal range of nearly two miles, with them any climates, and consequently numerous varieties of flora.
Its migrations consisting more of altitudinal movements than of longitudinal.
A more serious possibility is that the altitudinal pattern may vary according to time or place.
The altitudinal extent of the pinyon-juniper association is from roughly 4000 to 6000 feet elevation.
