Base visibility in good snowshoe hare habitat ranges from 2% at 16.5 feet (5 m) distance to 0% at 66 feet (20 m). Travel cover is slightly more open, ranging from 14.7% visibility at 16.5 feet (5 m) to 2.6% at 66 feet (20 m). Areas with horizontal vegetation density of 40 to 100% at 50 feet (15 m) are adequate snowshoe hare habitat in Utah. [25]
Other examples of these models include the Lotka-Volterra model of the snowshoe hare and Canadian lynx in North America, [26] any infectious disease modeling such as the recent outbreak of SARS [27] and biological control of California red scale by the introduction of its parasitoid, Aphytis melinus.

In North America, the phenomenon was identified in populations of the snowshoe hare. [1] [2] In 1865, trappers with the Hudson's Bay Company were catching plenty of animals. By 1870, they were catching very few. It was finally identified that the cycle of high and low catches ran over approximately a ten-year period.
Canada lynxes eat snowshoe hares. None of the assumptions above are likely to hold for natural populations. Nevertheless, the Lotka–Volterra model shows two important properties of predator and prey populations and these properties often extend to variants of the model in which these assumptions are relaxed:
One genus, Lepus, contains 32 species that are collectively referred to as hares; the other eight genera are generally referred to as rabbits, with the majority – 19 species – in Sylvilagus, or the cottontail rabbits. Over one hundred extinct Leporidae species have been discovered, though due to ongoing research and discoveries the exact ...
These species survive year-round in taiga by changing fur color and growing extra fur. They have adapted to use each other to survive too. All of the predators depend on the snowshoe hare at some point during the year. All of the species also depend on forests in the area for shelter.
Skeleton of Alaskan Hare on display at the Museum of Osteology. Leporidae (/ l ə ˈ p ɔː r ɪ d iː,-d aɪ /) is the family of rabbits and hares, containing over 70 species of extant mammals in all.
Lagomorpha is an order of placental mammals, comprising the rabbits, hares, and pikas. Members of this order are called lagomorphs. Members of this order are called lagomorphs. It currently comprises 93 extant species, which are grouped into 12 genera .
