The Greater Sage-grouse (Centrocercus urophasianus) is the largest members of the Phasianoidae family in the United States. The Sage-grouse is a ground-dwelling species living predominantly in Sagebrush (Artemisia spp.) step habitat (Connelly et al., 2004). The Sage-grouse is a polygynous species where, one male will breed with multiple females, further, they exhibit a clumped polygyny where Sage-grouse migrate to breeding areas called a “Lek”. The males exhibit several courtship displays during
of arid or semi-arid regions to desert-like conditions, which support: little vegetation, a low soil fertility and high evaporation rates (Haggett, 2001). This work will overlook how deserts are measured by a variety of different means. To measure the growth of deserts characteristics need to be obtained. By creating set indicators for deserts the spread of desertification can be gauged. Climate (Anderson,2001) is one of the larger indicators of the spread of deserts: as you can see from
entered the area in 1540 until 1542 during its search for Cibola. However, he did not find it. He only found little Indian villages, including the settlement of the Zuni Pueblos, which probably had inspired the false legend. The next European in the region was Father Kino, a member of the Society of Jesus. In 1690s and early 18th century he converted many of the Indians in the Pimería Alta, now southern Arizona and northern Sonora, to Christianity. After being part of Spain for centuries, Arizona became
The Aral Sea Disaster Abstract The Aral Sea and the entire Aral Sea basin area have achieved worldwide notoriety due to the environmental disaster. The example of the Aral Sea disaster has sent a signal to the entire international community demonstrating how fast and irrevocable the environmental system can be ruined if there is no long-term thinking and planning in place. This paper gives a broad overview of the policies that have resulted in dying of the forth-largest inland body of water
because they involve the removal of resources of an area in which other inhabitants are dependent upon. A great example of this regrettable indirect expansion is the loss of the rich habitat of the area known as Owens Valley. Owens Valley History Owens Valley lies to the east of the Sierra Nevada mountain and west of the White-Inyo mountain ranges, just to the west of the U.S.’s Great Basin. Early settlers to this area, as all other immediate surrounding area’s originally, were Indians, one of
other cultural elements. The two last regions and the Bible are the most important antecedents of the modern western world that owe something to Egypt. The western alphabet is derived from a Phoenician one possibly modeled on Egyptian hieroglyphs; Egyptian ideas are found in some parts of the Bible; and Greek sciences and especially, art were originally influenced by Egypt. Finally, archaeology and historical writing have made Egypt a subject of great public interest, stimulating many books

by severe inflation and an enormous foreign debt brought on in large part by precipitous declines in the value of petroleum products. Geologically, Mexico is located in one of the Earth's most dynamic areas. It is a part of the "Ring of Fire," a region around the Pacific Ocean highlighted by active volcanism and frequent seismic activity. Within the context of plate tectonics, a theory developed to explain the creation of major landform features around the world, Mexico is situated on the western
