Edwin James (scientist)
Edwin P. James (August 27, 1797 – October 28, 1861), a 19th-century American botanist, geologist, linguist, and medical practitioner, was an important figure in the early exploration of the American West. James was also known for his time spent creating relationships with Native Americans in the United States, and also aiding African Americans to escape slavery. James is primarily remembered for his participation in the Stephen H. Long's Expedition of 1820, expedition of 1819-1820 led by Major Stephen Harriman Long, into still largely unknown territory acquired in the Louisiana Purchase. James served during the expedition's more productive second year. That expedition "was the first scientific survey of the region and dramatically increased the country’s geographical knowledge of the West." James was primarily responsible for producing the report, ''Account of an Expedition from Pittsburgh to the Rocky Mountains, Performed in the Years 1819, 1820'', published in 1823. During ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine Tundra
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated alpine climate, harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with tundra#Arctic tundra, polar tundra. The high elevation causes an adverse climate, which is too cold and windy to support tree growth. Alpine tundra ecotone, transitions to sub-alpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as ''Krummholz''. With increasing elevation it ends at the snow line where snow and ice persist through summer. Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground. The cold climate of the alpine tundra is caused by adiabatic cooling of air, and is similar to polar climate. Geography Alpine tundra occurs at hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree Line
The tree line is the edge of the habitat at which trees are capable of growing. It is found at high elevations and high latitudes. Beyond the tree line, trees cannot tolerate the environmental conditions (usually cold temperatures, extreme snowpack, or associated lack of available moisture). The tree line is sometimes distinguished from a lower timberline, which is the line below which trees form a forest with a closed Canopy (biology), canopy. At the tree line, tree growth is often sparse, stunted, and deformed by wind and cold. This is sometimes known as ''krummholz'' (German for "crooked wood"). The tree line often appears well-defined, but it can be a more gradual transition. Trees grow shorter and often at lower densities as they approach the tree line, above which they are unable to grow at all. Given a certain latitude, the tree line is approximately 300 to 1000 meters below the permanent snow line and roughly parallel to it. Causes Due to their vertical structure, tree ...

Pikes Peak
Pikes Peak is the List of mountain ranges of Colorado#Mountain ranges, highest summit of the southern Front Range of the Rocky Mountains, in North America. The Ultra-prominent peak, ultra-prominent fourteener is located in Pike National Forest, west of downtown Colorado Springs, Colorado. The town of Manitou Springs, Colorado, Manitou Springs lies at its base. The mountain is named in honor of American explorer Zebulon Pike (though he was unable to reach the summit). The summit is higher than any point in the United States east of its longitude. Name The band of Ute people who called the Pikes Peak region their home were the Tabeguache, whose name means the "People of Sun Mountain". or "sun", is the Ute language, Ute word that was given by these first people to the mountain that we now call Pikes Peak. It is thought that the Ute people first arrived in Colorado about 500 A.D., however their oral history states that they were created on Tava. In the 1800s, when the Arapa ...

Fort Smith National Historic Site
Fort Smith National Historic Site is a National Historic Site located in Fort Smith, Arkansas, along the Arkansas River. The first fort at this site was established by the United States in 1817, before this area was established as part of Indian Territory. It was later replaced and the second fort was operated by the US until 1871. This site was designated as a National Historic Landmark in 1961. The fort was the first site of the United States District Court for the Western District of Arkansas, which had jurisdiction over western Arkansas and all of Indian Territory. It began operations in 1875 with the appointment of Isaac C. Parker as the first federal district judge here. The town of Fort Smith, Arkansas developed around the fort. Description The site includes the second historic fort constructed at this place. In addition, located on the grounds are the foundation remains of the first Fort Smith (1817–1824), the commissary building (c. 1838) and a reconstruction of t ...

Front Range
The Front Range is a mountain range of the Southern Rocky Mountains of North America located in the central portion of the U.S. State of Colorado, and southeastern portion of the U.S. State of Wyoming. It is the first mountain range encountered as one goes westbound along the 40th parallel north across the Great Plains of North America. The Front Range runs north-south between Casper, Wyoming, and Pueblo, Colorado, and rises nearly 10,000 feet above the Great Plains. Longs Peak, Mount Evans, and Pikes Peak are its most prominent peaks, visible from the Interstate 25 corridor. The area is a popular destination for mountain biking, hiking, climbing, and camping during the warmer months and for skiing and snowboarding during winter. Millions of years ago, the present-day Front Range was home to ancient mountain ranges, deserts, beaches, and even oceans. The name "Front Range" is also applied to the Front Range Urban Corridor, the populated region of Colorado and Wyoming just ...

Platte River
The Platte River () is a major river in the State of Nebraska. It is about long; measured to its farthest source via its tributary, the North Platte River, it flows for over . The Platte River is a tributary of the Missouri River, which itself is a tributary of the Mississippi River which flows to the Gulf of Mexico. The Platte over most of its length is a broad, shallow, meandering stream with a sandy bottom and many islands—a braided stream. The Platte is one of the most significant tributary systems in the watershed of the Missouri, draining a large portion of the central Great Plains in Nebraska and the eastern Rocky Mountains in Colorado and Wyoming. The river valley played an important role in the westward expansion of the United States, providing the route for several major emigrant trails, including the Oregon, California, Mormon and Bozeman trails. The first Europeans to see the Platte were French explorers and fur trappers about 1714; they first called it the '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineer Cantonment
Engineer Cantonment is an archaeological site in Washington County, in the state of Nebraska in the Midwestern United States. Located in the floodplain of the Missouri River near present-day Omaha, Nebraska, it was the temporary winter camp of the scientific party of the Yellowstone Expedition. From October 1819 to June 1820, the party studied the geology and biology of the vicinity, and met with the local indigenous peoples. Their eight-month study of the biota has been described as "the first biodiversity inventory undertaken in the United States". The site was not used again after the departure of the expedition, and its location was forgotten. In 2003, it was rediscovered, and investigated during the 2003–05 archaeological seasons. In 2015, it was listed in the National Register of Historic Places. History The 1803 purchase of the Louisiana Territory from France gave the United States a claim to the watershed of the Missouri River. The Lewis and Clark expeditio ...
