Fresno Kangaroo Rat
The Fresno kangaroo rat or San Joaquin kangaroo rat (''Dipodomys nitratoides'') is a species of rodent in the family Heteromyidae. It is endemic to areas within and near the San Joaquin Valley of California in the United States. Habitat destruction due to agricultural development and urbanization has put this species at risk, and the International Union for Conservation of Nature has assessed its conservation status as " vulnerable". There are three subspecies of ''D. nitratoides'': * ''D. n. exilis'' (Fresno subspecies), * ''D. n. nitratoides'' (Tipton subspecies), * ''D. n. brevinasus'' (short-nose subspecies). Description The Fresno kangaroo rat is the smallest of the kangaroo rats in its genus, and has a head-and body length of about . Like other members of the genus, its tail, which is tipped with a large tuft of fur, is longer than the head and body combined. Kangaroo rats do not run, but use their powerful hind limbs to jump as in the manner of a kangaroo, using their ...

San Joaquin Valley
The San Joaquin Valley ( ; es, Valle de San Joaquín) is the area of the Central Valley of the U.S. state of California that lies south of the Sacramento–San Joaquin River Delta and is drained by the San Joaquin River. It comprises seven counties of Northern and one of Southern California, including, in the north, all of San Joaquin and Kings counties, most of Stanislaus, Merced, and Fresno counties, and parts of Madera and Tulare counties, along with a majority of Kern County, in Southern California. Although the valley is predominantly rural, it has densely populated urban centers: Fresno, Bakersfield, Stockton, Modesto, Tulare, Visalia, Hanford, and Merced. The first European to enter the valley was Pedro Fages in 1772. The San Joaquin Valley was originally inhabited by the Yokuts and Miwok peoples. The Tejon Indian Tribe of California is a federally recognized tribe of Kitanemuk, Yokuts, and Chumash indigenous people of California. Their ancestral homeland ...

Natural History Of The Central Valley (California)
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Endemic Fauna Of California
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ...

Dipodomys
Kangaroo rats, small mostly nocturnal rodents of genus ''Dipodomys'', are native to arid areas of western North America. The common name derives from their bipedal form. They hop in a manner similar to the much larger kangaroo, but developed this mode of locomotion independently, like several other clades of rodents (e.g. dipodids and hopping mice). Description Kangaroo rats are four or five-toed heteromyid rodents with big hind legs, small front legs, and relatively large heads. Adults typically weigh between Nader, I.A. 1978"Kangaroo rats: Intraspecific Variation in ''Dipodomus spectabilis'' Merriami and ''Dipodomys deserti'' Stephens" ''Illinois biological monographs''; 49: 1-116. Chicago, University of Illinois Press. The tails of kangaroo rats are longer than both their bodies and their heads. Another notable feature of kangaroo rats is their fur-lined cheek pouches, which are used for storing food. The coloration of kangaroo rats varies from cinnamon buff to dark gray, dep ...
