Vegetation Analysis: A Graphical Analysis Of Plant Succession In Desert Communities Affected By Fire, Jeff Lantow
Vegetation Analysis: A Graphical Analysis Of Plant Succession In Desert Communities Affected By Fire, Jeff Lantow
UNLV Theses, Dissertations, Professional Papers, and Capstones
The Mojave Desert is affected by fire every year. With each fire comes the removal of old growth and, in its place, new growth – consisting primarily of those species which thrive in disturbed areas. The focus of my research is to look at plant communities that have been disturbed by fire, and examine the successional pathway of these disturbed environments. The seven environments I analyzed were burned within the last twenty years and are found in the Coleogyne ramosissima ecotone throughout the Spring Mountain range near Las Vegas, Nevada. The data was collected with randomly chosen circle plots in …
Water Conservation In The Las Vegas Valley, Judith M. Keir
Water Conservation In The Las Vegas Valley, Judith M. Keir
UNLV Theses, Dissertations, Professional Papers, and Capstones
This thesis deals primarily with residential use of water in the Las Vegas Valley, an arid climate located in the Mojave Desert, and whether the education of people living here has any bearing on whether or not they conserve water. Many of the residents of the Las Vegas Valley have moved from other areas of the country, and perhaps are not aware of the fact that there is a limited supply of water available to the Valley. I believe that people are not necessarily wasteful, and that they would want to conserve water, if they were aware that conservation and …

A number of agencies sample Lake Mead and the Las Vegas Wash on a routine basis at several locations. In order to share and properly interpret the data, the Bureau of Reclamation, Southern Nevada Water Authority and the three Wastewater Treatment Facilities (City of Las Vegas, Clark County Sanitation District and City of Henderson) formed a committee to examine sampling and analytical protocols and to share information with the goal of maximizing the data quality. The group first met in April 1997.
It was agreed that an effort should be made to discuss and compare specific sampling and analytical techniques …
Effects Of Oxygen Variation On The Ecology Of Devil's Hole, Death Valley National Park, Norma J. Azad
Effects Of Oxygen Variation On The Ecology Of Devil's Hole, Death Valley National Park, Norma J. Azad
UNLV Theses, Dissertations, Professional Papers, and Capstones
The inability to rear Devil's Hole pupfish, Cyprinodon diabolis Wales, in captivity, when captive propagation has been successful with other species of pupfish, led to the examination of environmental factors which are unique to Devil's Hole. It has been suggested that C. diabolis regularly experience developmental arrest due to hypoxic conditions. This arrest may be reversible in areas of the shallow shelf during periods of photosynthetic activity. Oxygen measurements over the shallow shelf reveal a gradient of oxygen variation with the greatest diel variability over the inner portion of the shelf diminishing to nearly imperceptible diel variation toward the outer …
