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 …

Agronomy, Horticulture and Plant Science Faculty Publications
Dominant carabid species present in crops and crop rotation sequences commonly used in the northern Great Plains were assessed as an initial step toward the management of carabids as natural control agents. Ground beetle populations were determined by pitfall trapping in 4 crop rotation treatments maintained under high, managed, and low levels of chemical fertilizer and pesticide inputs. Diversity and species richness among crops, rotations, and input levels were compared using 3 indices—the Shannon-Weaver Index, relative diversity, and the Hierarchical Richness Index (HRI). Four carabid species, Cyclotrachelus altemans (Casey), Poecilvs lucublandus Say, Harpalns pensylvanicus (DeGeer), and Bembidion quadrimaculatum L., comprising …

Reproductive Success Of Ospreys At Two Sites In Connecticut, Donna Christine O'Neill, Robert A. Askins
Reproductive Success Of Ospreys At Two Sites In Connecticut, Donna Christine O'Neill, Robert A. Askins
Biology Faculty Publications
Nest success rates and rates of fish delivery to nests were determined for two large Osprey populations in COlmecticut, one at Groton Reservoir, Groton, and one at Great Island, Old Lyme, during 1996 and 1997. Between 1993 and 1996 these Osprey populations had substantially different rates of nest success. Great Island Ospreys fledged few young while Groton Reservoir Ospreys had good nest success. During 1997, however, fledging rates were similar at the two sites. In 1996, low nest success at Great Island 'resuited from high predation rates, probably due to raccoons. The higher nest success rate at this site in …

Fisheries Research Reports
To address the concern expressed by Commercial rock lobster fishers operating in the Abrolhos Islands area, that expanding saucer scallop trawl activity was damaging the sea floor biota in areas which they considered good rock lobster habitat and poor scallop habitat, an underwater video survey was conducted by the Fisheries Department Research Division, with the following objectives:
1. Examine, classify and map the benthic habitat of areas currently and historically trawled for scallops in the Abrolhos Islands area and adjacent waters;
2. Examine, classify and map the benthic habitat of areas adjacent to these trawled areas, where potential for conflict …

Wild Primate Populations In Emerging Infectious Disease Research: The Missing Link?, Nathan D. Wolfe, Ananias A. Escalante, William B. Karesh, Annelisa Kilbourn, Andrew Spielman, Altaf A. Lal
Harold W. Manter Laboratory of Parasitology: Library Materials
Wild primate populations, an unexplored source of information regarding emerging infectious disease, may hold valuable clues to the origins and evolution of some important pathogens. Primates can act as reservoirs for human pathogens. As members of biologically diverse habitats, they serve as sentinels for surveillance of emerging pathogens and provide models for basic research on natural transmission dynamics. Since emerging infectious diseases also pose serious threats to endangered and threatened primate species, studies of these diseases in primate populations can benefit conservation efforts and may provide the missing link between laboratory studies and the well-recognized needs of early disease detection, …

Factors Concerning The Conservation Of A Rare Shale Endemic Plant: The Reproductive Ecology And Edaphic Characteristics Of Penstemon Debilis (Scrophulariaceae), Amy L. Mcmullen
Biology
The management of a rare, edaphic endemic plant species requires an understanding of the ecological setting and processes that contribute to its restriction. Included in the ecological processes is a set of biotic characters associated with the reproductive ecology, including its breeding system, pollination vectors, and germination requirements. The geologic and soil setting of the plant must also be characterized in order to understand the plant's restriction to the substrate. These issues were addressed by this study of the rare endemic Penstemon debilis O'Kane and Anderson (Scrophulariaceae). Penstemon debilis consists of six populations that occur on talus slopes of the …

The Biology Of Xenopus By R. C. Tinsley And H. C. Kobel, Rafael O. De Sá
The Biology Of Xenopus By R. C. Tinsley And H. C. Kobel, Rafael O. De Sá
Biology Faculty Publications
The Biology of Xenopus presents a summary of current knowledge about a single genus resulting from a symposium held at the Zoological Society of London in September 1992. This approach to summarizing available information has also been taken for other taxa, such as Atelopus (Lotters, 1996). However, the task of compiling data for Xenopus is enormous relative to any other amphibian group, because Xenopus laevis has become a model system for molecular and development research (Cannatella and de Sa, 1993). Unfortunately, most of our knowledge of Xenopus is biased toward this single species. There are about 20 recognized species of …
Utilization Of Spatially Distributed Soil Resources By Several Species Common To The Great Basin, Sarah Duke
Utilization Of Spatially Distributed Soil Resources By Several Species Common To The Great Basin, Sarah Duke
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Heterogeneous spatial and temporal distributions of soil resources important to plant growth have been documented in the sagebrush steppe ecosystem. There can exist as much variability in soil resources within the root zone of individual plants as exists across an entire field. The objective of this dissertation research was to evaluate how plants respond to, utilize and influence the spatial heterogeneity of soil resources. The three specific sets of questions addressed are outlined in the three main chapters of this dissertation.
My first study addressed how the number and concentration of phosphorus (P) patches in the root zone of an …

Perceived Fairness And Effectiveness Of Rangeland Collaborative Processes, Kimberly J. Richardson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Involvement in collaborative partnerships in natural resource management has become a popular method for natural resource management agencies to collect public input, cope with conflicts, and develop ecosystem management plans. This thesis evaluates various collaborative processes, emphasizing multiple-owner partnerships. Qualitative interviews of 46 landowners in Utah were conducted to reveal concerns and suggestions regarding multiple-owner landscape-level collaborative partnerships. Landowners were concerned about private property rights infringement and losing control of their private land. Landowners were primarily concerned about the fairness and effectiveness of any partnership in which they were involved.
However, they were willing to consider participating if certain procedural …

Limitations On Canada Goose Production At Fish Springs National Wildlife Refuge, Utah, Dorie S. Stolley
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Canada geese (Branta canadensis) recently have become management problems in some areas due to overpopulation. At Fish Springs National Wildlife Refuge (NWR), managers are concerned with the opposite situation. Despite attempts to boost production, only 18 to 34 goslings of the western Canada goose (B. c. moffitti) were produced per year, from 1989 to 1993. I studied the breeding population from March to July in 1996 and 1997. Results suggest that production is limited in 3 ways: low gosling survival, low nesting success for ground nests, and low number of breeding pairs.
Gosling survival to fledging …

Temperature Sensitivity Of El Tor 01, Classical 01, And 0139 Vibrio Cholerae, Michelle Angela O'Neill
Temperature Sensitivity Of El Tor 01, Classical 01, And 0139 Vibrio Cholerae, Michelle Angela O'Neill
Dissertations and Theses
Vibrio cholerae has long been recognized as the causative agent of the disease cholera, but what has only become evident in recent years is the role of the environment in cholera. The cholera bacterium is found autochthonously in the marine and estuarian environment, and if there is any hope of controlling the disease the environmental aspects must be understood.
The central questions addressed in this study were how bacterial survival was influenced by temperature and the role that available nutrients play in V. cholerae survival. Survival of three different V. cholerae strains [classical (01); El Tor (01), and El Tor …
A Comparison Of Encephalization Between Odontocete Cetaceans And Anthropoid Primates, L. Marino
A Comparison Of Encephalization Between Odontocete Cetaceans And Anthropoid Primates, L. Marino
Veterinary Science and Medicine Collection
There have been very few studies of brain size and encephalization in cetaceans and essentially none that have made direct quantitative comparisons of cetaceans and another mammalian group using large normative samples. In the present study two different measures of encephalization were calculated and used to rank and compare 21 odontocete species and 60 anthropoid primate species. Comparisons were made both within and between the two groups. Results show that the encephalization level of Homo sapiens is still extraordinary relative to that of nonhuman species. Nevertheless, a subset of delphinid odontocetes are significantly more highly encephalized than the most highly …

Effect Of Sampling Errors On Estimates Of Recruitment And Fishing Mortality From Separable Virtual Population Analysis, Emmanis Dorval
Effect Of Sampling Errors On Estimates Of Recruitment And Fishing Mortality From Separable Virtual Population Analysis, Emmanis Dorval
Biological Sciences Theses & Dissertations
Separable virtual population analysis (SVPA) models provide estimates of historical recruitment and fishing mortality from analyzing catch data based on the separability of fishing mortality into age specific-gear selection and yearly mortality. These models assume that the catch is randomly sampled and that sampling error is a random variable with constant variance and mean equal to zero. These models do not account for sampling measurement errors that occur when the catch partitioned by age is not measured on every sampling unit without error, and spatio-temporal errors that occur when the observed catch is not representative of the harvested population throughout …
Studies On The Biology Of Striga Aspera (Scrophulariaceae) In Nigeria, Emmanuel Izaka Aigbokhan
Studies On The Biology Of Striga Aspera (Scrophulariaceae) In Nigeria, Emmanuel Izaka Aigbokhan
Biological Sciences Theses & Dissertations
Studies on Striga aspera are few and little information exists on its relationship with the morphologically similar and much studied S. hermonthica. Both species are sympatric in West Africa and if they hybridize, may serve as virulent gene reservoirs for each other.
The primary focus of this study was on the biology of S. aspera in Nigeria. The research focussed on its distribution, phenology, cytology, hybridization, seed dormancy, viability and germination in relation to S. hermonthica. Related studies involving the hybrids include genetic and morphological variability, pathogenicity and the simultaneous dual infection of a maize plant by both species.
