First, of primary importance is the fact that the pattern of camp movement com-
prises a Lévy flight. The movements are not distributed in a Gaussian or exponen-
tial mode, as might be expected, but as a power function. When migration and
diffusion are modeled, researchers typically assume a Gaussian distribution of
migration distances. Lévy flight movements may help explain rapid, long-distance
migrations that advance through processes such as leapfrogging (Anthony 1990).
Lévy flights can produce faster long-distance migration than Brownian motion
because the latter will have few long jumps and many medium-length jumps,
whereas the former will produce some surprisingly long leaps.
