Tikaboo Valley
Tikaboo Valley is a valley in Lincoln County, Nevada, United States. Its geographical coordinates are 37.1563494 and -115.4016881. It has an elevation of 3,793 feet or 1,156 meters. Climate The climate there is dry, even on cool mornings after a rainfall. Fauna Biologist Chris Smith has studied flora and fauna in the area including Joshua trees and moths. It appears that this may be the only place where two types of Joshua tree, namely the Eastern and Western varieties have come together. Part of the reason for this is the possibility of Climate change which could account for the northward appearance of a hybridized species.''High Country News'' April 28, 201Joshua trees may be migrating north in response to climate change/ref> Military use B-52H and B-1B Bombers often do low-level runs there. There have been other military tests there. See also * List of valleys of Nevada This is a list of valleys of Nevada. Valleys are ordered alphabetically, by county. Dramatic Parallel ( ...

Lincoln County, Nevada
Lincoln County is a County (United States), county located in the U.S. state of Nevada. As of the 2010 United States Census, 2010 census, the population was 5,345. Its county seat is Pioche, Nevada, Pioche. Like many counties in Nevada, it is dry and sparsely populated, though notable for containing the Area 51 government Air Force base. History Lincoln County was established in 1866 after Congress enlarged Nevada by moving its state line eastward and southward at the expense of Utah Territory, Utah and Arizona Territory, Arizona territories. It is named after Abraham Lincoln, the 16th President of the United States. Original legislation called for the creation of a "Stewart County", after Nevada Senator William M. Stewart, but this was later changed in a substitute bill.

Chris Smith (professor)
Chris Smith is an associate professor of biology at Willamette University in Salem, Oregon, United States. In 2013 he received a grant for his work studying the relationship between yucca moths and yucca trees. Background In 2013, Smith received a National Science Foundation CAREER award of $850,000 for his work studying the co-evolution of yucca trees and their pollinators, yucca moths. He had the distinction of being the university's first faculty member to receive a CAREER award. With Emily Drew, Smith also teaches the interdisciplinary course "Race, Racism, and Human Genetics", which examines how scientific endeavors had been affected by racial outlooks. The course originated from a discussion Smith and Drew had on the topic in 2012. Study of yucca and joshua trees Smith has studied the northward migration of yucca and joshua trees, and the possible hybridization of the Eastern and Western varieties, either of which may be related to climate change.

Yucca Brevifolia
''Yucca brevifolia'' is a plant species belonging to the genus ''Yucca''. It is tree-like in habit, which is reflected in its common names: Joshua tree, yucca palm, tree yucca, and palm tree yucca. This monocotyledonous tree is native to the arid Southwestern United States, specifically California, Arizona, Utah, and Nevada, and to northwestern Mexico It is confined mostly to the Mojave Desert between elevation. It thrives in the open grasslands of Queen Valley and Lost Horse Valley in Joshua Tree National Park. Other regions with large populations of the tree can be found northeast of Kingman, Arizona in Mohave County; and along U.S. 93 between the towns of Wickenburg and Wikieup, a route which has been designated the Joshua Tree Parkway of Arizona. The common name Joshua tree apparently comes from Christian iconography. Taxonomy The Joshua tree is also called ''izote de desierto'' (Spanish, "desert dagger"). It was first formally described in the botanical literature as ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Central Basin And Range Ecoregion
The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range. The desert is a geographical region that largely overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, and the Central Basin and Range ecoregion defined by the U.S. Environmental Protection Agency and United States Geological Survey. It is a temperate desert with hot, dry summers and snowy winters. The desert spans large portions of Nevada and Utah, and extends into eastern California. The desert is one of the four biologically defined deserts in North America, in addition to the Mojave, Sonoran, and Chihuahuan Deserts. Basin and range topography characterizes the desert: wide valleys bordered by parallel mountain ranges generally oriented north–south. There are more than 33 peaks within the desert with summits higher than , but valleys in the region are also high, most with elevations above . The biological communities of the Great Basin Desert vary accordi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valleys Of Nevada
A valley is an elongated low area often running between Hill, hills or Mountain, mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacier, glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glaciation, glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In karst, areas of limestone bedrock, dry valleys may also result from drainage now taking place cave, underground rather than at the surface. Rift valleys arise principally from tectonics, earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms th ...
