The Lake Mead National Recreational Area was created by the construction of the Hoover Dam during the years 1931-1936. In January 2007, the quagga mussel (Dreissena rostriformis bugensis), was found in Lake Mead. This became the first known Dreissenid species in the southwest and the only time a large water system was first infested by the quagga mussel and not the zebra mussel (Dreissena polymorpha). This invasive species has quickly spread to Lake Mohave and further down the lower Colorado River drainage. The microscopic size (70 µm or larger) of the veliger life stage makes it impossible to see with …

The expansion of civilization across all borders of the world has proven to affect major components of ecosystems. Since the introduction and establishment of the aquatic invasive species (AIS),Dreissena rostiformis bugensis, commonly known as the quagga mussel, into the United States there has been an extensive amount of time and money spent on controlling and preventing their expansion across the United States. The quagga mussel is of major concern because of its ability to disrupt the ecological communities in previously non-infested bodies of water, which may cause a loss in biodiversity and effect environmental health. The quagga mussel has spread …


Unintentional Home Injury Risks Among The Elderly In Southern Nevada, Michelle Echauz Ching Aug 2012

Unintentional Home Injury Risks Among The Elderly In Southern Nevada, Michelle Echauz Ching

UNLV Theses, Dissertations, Professional Papers, and Capstones

The elderly population (65 years of age and older) is one of the fastest growing populations in the US. A major public health concern involving the elderly population is unintentional injuries in the home. Since elderly adults typically spend the majority of their time in the home, minimizing unintentional home injury hazards is crucial for this population. The Nevada Healthy Homes Partnership (NHHP) program is a grant funded effort that helps to improve the quality and availability of safe and healthy homes in Nevada. Therefore, the purpose of this study is to determine the effectiveness of the NHHP program interventions …
