Edward William Nelson
Edward William Nelson (May 8, 1855 – May 19, 1934) was an American naturalist and ethnologist. A collector of specimens and field naturalist of repute, he became a member of several expeditions to survey the fauna and flora. He was part of a team with Clinton Hart Merriam that took part in the Death Valley Expedition. He also explored the Yosemite Valley. A number of vertebrate species are named after him. Biography Nelson was born in Manchester, New Hampshire, on May 8, 1855, the first son of William and Martha () Nelson. Nelson and his brother then lived with his maternal grandparents in the Adirondacks when his father joined the Union Army and mother went to Baltimore as a nurse. Here he fell in love with the wilderness. Nelson moved to Chicago after his father was killed in the Civil War and his mother established a dressmaking business. In 1871, his large insect collection was lost in the Chicago Fire and the family was left homeless. This was the time that h ...

Edward William Nelson 1900s
Edward is an English given name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortune; prosperous" and '' weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the Norman and Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III named his firstborn son, the future Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration. Variant forms The name has been adopted in the Iberian peninsula since the 15th century, due to Edward, King of Portugal, whose mother was English. The Spanish/Portuguese forms of the name are Eduardo and Duarte. Other variant forms include French Édouard, Italian Edoardo and Odoardo, German, Dutch, Czech and Romanian Eduard and Scandinavian Edvard. Short forms include Ed, Eddy, Eddie, Ted, Teddy and Ned.

Desert Bighorn Sheep
The desert bighorn sheep (''Ovis canadensis nelsoni'') is a subspecies of bighorn sheep (''Ovis canadensis'') that is native to the deserts of the United States' intermountain west and southwestern regions, as well as northwestern Mexico. The Bureau of Land Management considered the subspecies "sensitive" to extinction. The trinomial of this species commemorates the American naturalist Edward William Nelson (1855–1934). The characteristics and behavior of the desert bighorn sheep generally follow those of other bighorn sheep, except for adaptation to the lack of water in the desert. They can go for extended periods of time without drinking water. The desert bighorn sheep is the state mammal of Nevada. It is also the mascot of the Universidad Autónoma de Baja California. Distribution The range of the desert bighorn sheep includes habitats in the Mojave Desert, Sonoran Desert, Great Basin Desert, and Chihuahuan Desert, as well as the Colorado Plateau.

Ammospermophilus Nelsoni
The San Joaquin antelope squirrel or Nelson's antelope squirrel (''Ammospermophilus nelsoni''), is a species of antelope squirrel, in the San Joaquin Valley of the U.S. state of California. Distribution and habitat The San Joaquin antelope squirrel is found in the San Joaquin Valley, including slopes and ridge tops along the western edge of the valley. It is endemic to the region, and is found in a much smaller range today than it originally inhabited. Since the San Joaquin Valley fell under heavy agricultural cultivation, habitat loss combined with rodenticide use has reduced the squirrels numbers enough that it is now listed as a threatened species. Most of today's remaining San Joaquin antelope squirrels can be found in the Carrizo Plain, where their original habitat remains undisturbed. The squirrels live in small underground familial colonies on sandy, easily excavated grasslands in isolated locations in San Luis Obispo and Kern Counties. Common vegetation associated with ...

Xenomys Nelsoni
The Magdalena rat (''Xenomys nelsoni'') is a species of rodent in the family Cricetidae which is found only in a small region of western Mexico. It is the only species in the genus ''Xenomys''. The common name comes from the village where the first specimen was collected, and the second part of the scientific name refers to the collector. Description The Magdalena rat is a relatively large member of its family, measuring in length, including the tail. Adults weigh an average of . The general body colour is cinnamon to yellowish brown, being paler on the head and fading to creamy white on the underparts. It can be distinguished from other local rat-like species by the presence of white spots above the eyes and behind the ears; the cheeks are also marked with white fur. The tail is both hairy and scaly, and is dark brown in colour. Distribution and habitat The species is endemic to Colima and southwest Jalisco, along the Pacific coast of Mexico. It is estimated to inhabit an a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oryzomys Nelsoni
''Oryzomys nelsoni'' is an extinct rodent of María Madre Island, Nayarit, Mexico. Within the genus ''Oryzomys'' of the family Cricetidae, it may have been most closely related to the mainland species '' O. albiventer''. Since its first description in 1898, most authors have regarded it as a distinct species, but it has also been classified as a mere subspecies of the marsh rice rat (''O. palustris''). After its discovery in 1897, it has never been recorded again and it is now considered extinct; the presence of introduced black rats on María Madre may have contributed to its extinction. ''Oryzomys nelsoni'' was a large species, distinguished in particular by its long tail, robust skull, and large incisors. It was reddish to yellowish above and mostly white below. Its diet may have included plant material and small animals. Taxonomy ''Oryzomys nelsoni'' was collected by Edward William Nelson and Edward Goldman in May 1897 and never found again.

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Nelson's Sparrow
Nelson's sparrow (''Ammospiza nelsoni'') is a small New World sparrow. This bird was named after Edward William Nelson, an American naturalist. Formerly, this bird and the saltmarsh sparrow were considered to be a single species, the sharp-tailed sparrow; because of this it was briefly known as Nelson's sharp-tailed sparrow. Description Measurements: * Length: 4.3-5.1 in (11-13 cm) * Weight: 0.6-0.7 oz (17-21 g) * Wingspan: 6.5-7.9 in (16.5-20 cm) Adults have brownish upperparts with gray on the crown and nape, a cream-colored breast with light or indistinct streaking and a white throat and belly; they have an orange face with gray cheeks and a short pointed tail. Their breeding habitat is marshes on the Atlantic coast of Canada and Maine, central Canada, (the Canadian Prairies region and a coastal strip on the south of Hudson Bay), and the north central United States. The nest is an open cup attached to vegetation and close to the ground. Due to their proximity to the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terrestrial Animal
Terrestrial animals are animals that live predominantly or entirely on land (e.g. cats, dogs, ants, spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g. fish, lobsters, octopuses), and amphibians, which rely on a combination of aquatic and terrestrial habitats (e.g. frogs and newts). Some groups of insects are terrestrial, such as ants, butterflies, earwigs, cockroaches, grasshoppers and many others, while other groups are partially aquatic, such as mosquitoes and dragonflies, which pass their larval stages in water. Terrestrial animals tend to be more developed and intelligent than aquatic animals. Terrestrial classes The term "terrestrial" is typically applied to species that live primarily on the ground, in contrast to arboreal species, which live primarily in trees. There are other less common terms that apply to specific groups of terrestrial animals: *Saxicolous creatures are rock dwelling. "Saxicolous" is derived from t ...
