One study of captive animals suggests that the species has some capacity to adapt its feeding habits to lower elevations. [16] The high temperatures in the mountains due to climate change are causing the Ili pika to migrate up and will eventually be forced to reach the peak, where it is occupied, and sooner the Ili pika will no longer have ...
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.

Although it is a marsupial, the Tasmanian pygmy possum superficially resembles a dormouse, and it is the smallest of all the known species of possum. [3] Adults range from 6.6 to 7.5 centimetres (2.6 to 3.0 in) in head-body length, with a 6 to 7.2 centimetres (2.4 to 2.8 in) tail, and weigh just 7 to 10 grams (0.25 to 0.35 oz). [4]

Chipmunks are classified as four genera: Tamias, of which the eastern chipmunk (T. striatus) is the only living member; Eutamias, of which the Siberian chipmunk (E. sibiricus) is the only living member; Nototamias, which consists of three extinct species, and Neotamias, which includes the 23 remaining, mostly western North American, species.
