Green Sea Turtle (Chelonia Mydas) Hatchlings Success: The Effects Of Artificial Lights And Other Human Impacts, Hui-Yu Tracy Liang
Green Sea Turtle (Chelonia Mydas) Hatchlings Success: The Effects Of Artificial Lights And Other Human Impacts, Hui-Yu Tracy Liang
UNLV Theses, Dissertations, Professional Papers, and Capstones
Sea turtles appeared more than 200 million years ago in the late Triassic period. They grow very slowly, taking an average of 25 years to reach sexual maturity, with a life span averaging 40-50 years. From May to October green sea turtles (Chelonia mydas) emerge during the night and follow light cues toward the sea. Recently, beachfront development has increased hatchling mortality rate. When hatchlings emerge from nest, high densities of artificial lights lead them toward the land where they either desiccate and die, or are preyed upon. Short-wavelength high intensity light and the distance of artificial light are the …
Two Different Soil Sampling Techniques For Assessing Soil Lead Concentrations At The Overton Wildlife Management Area, Nevada, Kristen E. Falc
Two Different Soil Sampling Techniques For Assessing Soil Lead Concentrations At The Overton Wildlife Management Area, Nevada, Kristen E. Falc
UNLV Theses, Dissertations, Professional Papers, and Capstones
During the summer of 1999, soil samples were taken from the Overton Wildlife Management Area (OWMA), located in the Moapa Valley of Clark County, Nevada. Although lead shot has been banned for the hunting of waterfowl since 1986, it is still legal for upland game hunting. The field sampled serves primarily as a dove hunting area and is cultivated. A large sample size was taken to indicate the short-term effects of the deposition of lead shot in the area and a small sample size, the long-term. Lead shot was recovered from 64% of the small samples and the estimated concentration …
Special Event Recycling: The Future Of Unlv's Recycling Program, Katherine A. Baker
Special Event Recycling: The Future Of Unlv's Recycling Program, Katherine A. Baker
UNLV Theses, Dissertations, Professional Papers, and Capstones
The current recycling program on the University of Nevada Las Vegas (UNLV) campus does not have a special event recycling aspect. The purpose of this study was to develop a special event recycling program and make recommendations of how to effectively implement it on the UNLV campus. In order to develop this special event recycling program data was collected through surveys and a pilot study. The data collected was then used to formulate recommendations. Recycling two different kinds of events, a walk and a concert tested those recommendations. Waste stream analyses were done on each event. The waste stream diversion …
