Dipodomys Ingens
The giant kangaroo rat (''Dipodomys ingens'') is an endangered species, endangered species of heteromyid rodent endemic to California. Description The giant kangaroo rat, is the largest of over 20 species of kangaroo rats, which are small members of the rodent family. It measures about in length, not including its long, tufted tail, and is tan or brown in color. Like other kangaroo rats it has a large head, large eyes, and long, strong hind legs which helps it hop quickly. The giant kangaroo rat lives on dry, sandy grasslands and digs burrows in loose soil. It lives in colonies, and the individuals communicate with each other by drumming their feet on the ground. These foot thumping signals range from single, short thumps to long, drawn out "footrolls" that can average over 100 drums at 18 drums per second. These audible signals serve both as a warning of approaching danger, as a territorial communication, and to communicate mating status. Kangaroo rats are primarily seed eate ...

Clinton Hart Merriam
Clinton Hart Merriam (December 5, 1855 – March 19, 1942) was an American zoologist, mammalogist, ornithologist, entomologist, ecologist, ethnographer, geographer, natural history, naturalist and physician. He was commonly known as the "father of mammalogy," a branch of zoology referring to the study of mammals. Early life Clinton Hart Merriam was born in New York City in 1855 to Clinton Levi Merriam, a U.S. congressman, and Caroline Hart, a judge's daughter and a graduate of Rutgers University, Rutgers Institute. The name Clinton, shared by both father and son, was in honor of New York governor DeWitt Clinton, whom the Merriam family had connections with. To avoid confusion, the younger Merriam went by his first initial combined with his middle name, his mother's maiden name, and thus often appears as C. Hart Merriam in both the literature of his time and thereafter. Although born in New York City, where his parents were staying the winter, the family home and place where Mer ...

Carrizo Plain National Monument
The Carrizo Plain (Obispeño language, Obispeño: ''tšɨłkukunɨtš'', "Place of the rabbits") is a large enclosed grassland plain, approximately long and up to across, in southeastern San Luis Obispo County, California, United States, about northwest of Los Angeles. The southern portion of the Carrizo Plain is within the Carrizo Plain National Monument, which also includes most of the Caliente Range.

ESA Endangered Species
The European Space Agency (ESA) is a 23-member international organization devoted to space exploration. With its headquarters in Paris and a staff of around 2,547 people globally as of 2023, ESA was founded in 1975 in the context of European integration. Its 2025 annual budget was €7.7 billion. The ESA Human and Robotic Exploration programme includes human spaceflight (mainly through participation in the International Space Station programme); as well as the launch and operation of missions to Mars and Moon. Further activities include science missions to Jupiter, Mercury, the Sun, Earth observation, Asteroid impact avoidance and Telecommunications missions, designing launch vehicles; and maintaining Europe's Spaceport, the Guiana Space Centre at Kourou (French Guiana). Further programmes include space safety, satellite navigation, applications and commercialisation. The main European launch vehicle Ariane 6 is operated through Arianespace with ESA sharing in the cost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Fauna Of California
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) IUCN Red List, Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have Environmental law, laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct.

Mammals Described In 1904
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Endemic Rodents Of The United States
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

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 tail of a kangaroo rat is longer than its body and head combined. 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, depend ...

Bitter Creek National Wildlife Refuge
The Bitter Creek National Wildlife Refuge is located in the foothills of the southwestern San Joaquin Valley in Kern County, California. The refuge is one of four units of the Hopper Mountain National Wildlife Refuge Complex for California condors. California condors Elevations on the Refuge range from . Purchased to protect dwindling California condor foraging and roosting habitat in 1985, the refuge is the site where the last wild female condor was trapped in 1986. The reintroduced condors feed and roost on the refuge. The refuge is an integral part of the Service's condor monitoring activities. The most notable physical features of the refuge are the San Andreas Fault, which bisects the refuge, and the dramatic Bitter Creek Canyon. As of July 2014, there is a total population of 437 condors living in sites in California, Baja California and Arizona. This includes a wild population of 232 and a captive population of 205. Sixty-eight free-flying Condors are managed by the US ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
