Retrospective Evaluation Of The Effects Of Human Disturbance And Goldfish Introduction On Endangered Pahrump Poolfish, James E. Deacon, Joshua E. Williams
Retrospective Evaluation Of The Effects Of Human Disturbance And Goldfish Introduction On Endangered Pahrump Poolfish, James E. Deacon, Joshua E. Williams
Western North American Naturalist
Life history data for Pahrump poolfish (Empetrichthys latos latos) collected from 1937 to 1975 were organized and analyzed to improve our understanding of changes caused by human habitat disruption and introduced goldfish (Carassius auratus) at Manse Spring, Nevada. Pahrump poolfish twice demonstrated their ability to recover numerically from a population crash. The first crash followed a November 1961 introduction of a few goldfish and subsequent removal of vegetation by local ranch children intent on turning Manse Spring into a swimming hole. The second crash followed another major habitat disturbance resulting from an unsuccessful attempt to eradicate …
Desiccation Sensitivity And Heat Tolerance Of Prunus Ilicifolia Seeds Dispersed By American Black Bears (Ursus Americanus), Mark Borchert, Claudia M. Tyler
Desiccation Sensitivity And Heat Tolerance Of Prunus Ilicifolia Seeds Dispersed By American Black Bears (Ursus Americanus), Mark Borchert, Claudia M. Tyler
Western North American Naturalist
Carnivore consumption of fruit is a principle means by which many fleshy-fruited plant species achieve long-distance seed dispersal. We examined carnivore dispersal of hollyleaf cherry (Prunus ilicifolia) seeds, specifically assessing the survival, desiccation sensitivity, and germination of seeds found in bear scats. Studies were conducted both in the laboratory and in 2 burn areas in Los Padres National Forest, California. Bear scats containing P. ilicifolia seeds were collected in burned and unburned chaparral. We counted seeds in each scat and noted whether endocarps had tooth punctures or rattled audibly when shaken. For comparative germination trials, we also collected …
Considerations For Wood River Sculpin Conservation: Historical Occurrence And Sampling Efficiency, Donald W. Zaroban
Considerations For Wood River Sculpin Conservation: Historical Occurrence And Sampling Efficiency, Donald W. Zaroban
Western North American Naturalist
Records of Wood River sculpin (Cottus leiopomus) from 1893 to 2003 were examined and new data were gathered in 2004 and 2006 to estimate the species’ historical range and to search for evidence of changes in its occurrence. Detections of Wood River sculpin were reported in 49 subwatersheds, primarily in the Idaho Batholith ecoregion. The remainder of the Wood River basin was classified as either potential historic range or unknown. Mark-recapture sampling was conducted to estimate the efficiency of electrofishing as a method to detect this sculpin. Sampling efficiency was calculated for 1 upstream pass and 1, 2, …
Mate Sampling In A Natural Population Of Pecos Gambusia, Gambusia Nobilis, John K. Leiser, Kimberly Little, Murray Itzkowitz
Mate Sampling In A Natural Population Of Pecos Gambusia, Gambusia Nobilis, John K. Leiser, Kimberly Little, Murray Itzkowitz
Western North American Naturalist
Much research has been conducted on the mating systems of poeciliid fish in aquaria; however, there are fewer studies that examine mate sampling of these fish in the wild. In general, male poeciliids are characterized as being unselective in their mate choices and will attempt to copulate with seemingly all available females. Females are selective, copulate infrequently, and are often pursued by “ardent” males who may force copulations. To avoid male harassment, females in aquaria will often shelter from males among other females in shoals. Here, we examined the mate-sampling behaviors of male and female Pecos gambusia Gambusia nobilis by …

Fecal Pellets Of American Pikas (Ochotona Princeps) Provide A Crude Chronometer For Dating Patch Occupancy, Lyle B. Nichols
Fecal Pellets Of American Pikas (Ochotona Princeps) Provide A Crude Chronometer For Dating Patch Occupancy, Lyle B. Nichols
Western North American Naturalist
American pikas (Ochotona princeps) seem to be especially vulnerable to climate change, with recent extinctions of pika populations being attributed to global warming. Incomplete historical location records are currently used to examine changes in pika distributions. A method of determining recent pika distributions in the absence of historical records is needed. Here I report on changes over time of known-age pika fecal pellets up to 36 years old. Predictable changes in diameter, internal consistency, and color of pellets provide a method to approximate the dates of last occupation in patches where pikas have been extirpated.

The Banner-Tailed Kangaroo Rat, Dipodomys Spectabilis (Rodentia: Heteromyidae), In Utah, George V. Oliver, Anthony L. Wright
The Banner-Tailed Kangaroo Rat, Dipodomys Spectabilis (Rodentia: Heteromyidae), In Utah, George V. Oliver, Anthony L. Wright
Western North American Naturalist
We report the discovery in Utah of Dipodomys spectabilis, a species previously unknown to occur in the state. We searched for D. spectabilis in extreme southeastern Utah, south of the San Juan River, and were successful in finding mounds and burrows characteristic of the species and in capturing one individual. This is the northernmost record for D. spectabilis and extends its known range ~84 km northwest of the nearest previously reported locality (Fruitland, San Juan County, New Mexico). A flea, Meringis rectus, collected from D. spectabilis, is also the first record of its species in Utah.

Rock Outcrops Harbor Native Perennials In Type-Converted Coastal Scrub, Robert J. Steers
Rock Outcrops Harbor Native Perennials In Type-Converted Coastal Scrub, Robert J. Steers
Western North American Naturalist
Type-conversion of coastal scrub to exotic annual grassland has been extensive in certain parts of southern California, especially in drier inland locales. Field observations suggest that rock outcrops harbor native perennials associated with coastal scrub vegetation after conversion to exotic annual grassland has occurred. Surveys were conducted to test this observation. In addition, measures of fossorial mammal disturbance, soil depth, exotic annual plant abundance, and soil moisture were collected and used to infer potential mechanisms that may influence patterns of native and exotic vegetation. Results showed that larger outcrops are associated with more native perennial species than smaller outcrops, consistent …

In recent years there has been a growing interest in the relationship between religion and the environment. The purpose of this project is to explore the environmental practices and attitudes of Christian churches in two Virginia Communities. The two communities; the Northern Neck and Eastern Shore are located on the Chesapeake Bay and have a shared history of dependence on the Bay. The results of the dissertation demonstrate the prevalence of environmental programs in the population, the nature of these programs and the respondents’ attitudes towards a host of environmental issues. These results can be used by environmental professionals and …
Trapping Mammals In A Cautious World: The Effect Of Disinfectants On Trap Success, J. A. Wilson, K. E. Mabry
Trapping Mammals In A Cautious World: The Effect Of Disinfectants On Trap Success, J. A. Wilson, K. E. Mabry
Western North American Naturalist
Disinfecting traps that have captured small mammals is one recommendation for preventing occurrence of hantavirus infection; however, the potential effects of disinfection on small mammal trappability have not been investigated thoroughly. We conducted an experiment to compare the effects of 2 disinfectants (Lysol® and household bleach) on the trappability of 4 small mammal species (Peromyscus maniculatus, Neotamias spp., and Spermophilus lateralis). We established triplicate trap grids in 2 forest types (red fir and mixed conifer), each consisting of a 6 × 6 array of Sherman live-traps placed at 10-m intervals. Traps were given 1 of 3 treatments: …
Pathology Of An Unusual Lumbar Condition In A Young Black Bear (Ursus Americanus) From The Big Bend Region Of Trans-Pecos Texas, Frederick B. Stangl Jr., Dana R. Mills, Michael W. Haiduk
Pathology Of An Unusual Lumbar Condition In A Young Black Bear (Ursus Americanus) From The Big Bend Region Of Trans-Pecos Texas, Frederick B. Stangl Jr., Dana R. Mills, Michael W. Haiduk
Western North American Naturalist
The skeleton of a young American black bear (Ursus americanus) possessing asymmetrical distortions of the 5 caudalmost lumbar neural spines was recovered from west Texas. We attribute this abnormality, presumed to be congenital, to the absence or atrophy of the right multifidus muscle straddling L3 and to the series of compensatory muscle adjustments required to maintain spinal alignment. This finding may have important management implications for black bears in Texas, given the possibility that our specimen originates from a partially isolated population.

Low Endemism, Continued Deep-Shallow Interchanges, And Evidence For Cosmopolitan Distributions In Free-Living Marine Nematodes (Order Enoplida), Holly M. Bik, W. Kelley Thomas, David H. Lunt, P. John D. Lambshead
Hubbard Center for Genome Studies (HCGS)
Background: Nematodes represent the most abundant benthic metazoa in one of the largest habitats on earth, the deep sea. Characterizing major patterns of biodiversity within this dominant group is a critical step towards understanding evolutionary patterns across this vast ecosystem. The present study has aimed to place deep-sea nematode species into a phylogenetic framework, investigate relationships between shallow water and deep-sea taxa, and elucidate phylogeographic patterns amongst the deep-sea fauna. Results: Molecular data (18 S and 28 S rRNA) confirms a high diversity amongst deep-sea Enoplids. There is no evidence for endemic deep-sea lineages in Maximum Likelihood or Bayesian phylogenies, …
From Seed To Harvest: A Comparative Life Cycle Assessment Of Conventional Vs. Organic Cotton Agriculture, Rebecca Hoehn
From Seed To Harvest: A Comparative Life Cycle Assessment Of Conventional Vs. Organic Cotton Agriculture, Rebecca Hoehn
Masters Theses, 2010-2019
Conventional and organic cotton farming practices both have benefits and detriments to each type. Cotton agriculture is responsible for the use of a third of the agriculture industries’ pesticide use. In order to help alleviate the use of pesticide dependency the following study reviews the use of pesticides as well as other stressors of both systems and hopes to decide how sustainable agriculture in the cotton industry can be attained. Evaluations of both systems have been compared in order to reach the decisions of sustainability.
The Role Of Quality Labels In Farming Diversification And Rural Development, Eman Vella
The Role Of Quality Labels In Farming Diversification And Rural Development, Eman Vella
Masters Theses, 2010-2019
The European Union promotes marketing of quality food products through a quality labelling scheme having three labels known as PDO, PGI and TSG. Protected Designation of Origin (PDO) and Protected Geographical Indication (PGI) are two labels that protect products with an association to a particular region. Such products need to have a traditional link with the area as well as unique attributes (known as specifications) that make the product different from the customary. PDO labels designate a product that is linked with an area in every aspect, while PGI labels indicate that the product has a unique geographical link in …

A Heuristic For Local Land Planning: Linking Ecological Function And Policy-In Context To Charlotte, North Carolina-, Kimberlee Robertella
Masters Theses, 2010-2019
Ecological systems and services are foundational to human well-being, and in recent years have received increasing scholastic attention. The functional ability of these systems is influenced however, by human-induced land transformation related to conventional patterns of growth and development. Such land transformations, which commonly occur as single-family residential development, are criticized as being wasteful and inefficient, leading to issues like air and water pollution, diminished forests and wetlands, and habitat loss and fragmentation. In the United States a patchwork of policy exists aimed at addressing such ecological concerns. Despite best efforts, most local governments and planning offices still miss the …
Exploring Sustainable Environmental Management Practices For Golf Courses In Semi-Arid Environments, Angelica V. Gurule
Exploring Sustainable Environmental Management Practices For Golf Courses In Semi-Arid Environments, Angelica V. Gurule
Masters Theses, 2010-2019
For the past several years NM government officials have been working to increase economic growth via tourism in NM. As a result several dozen golf courses have popped up around the state. Golf courses are conceived to be problematic as they consume large quantities of water and typically use lots of harmful pesticides to manage turfgrass. Water scarcity has already shown its face in NM: there are drought plans in place and growing evidence that illustrates the decrease in precipitation and an increase in temperatures, which will further reduce water resources. The scope of this paper is to analyze the …
Assessing Vulnerability To Coastal Hazards Case Study: Gozo, Jonathan Portelli
Assessing Vulnerability To Coastal Hazards Case Study: Gozo, Jonathan Portelli
Masters Theses, 2010-2019
All coastal areas around the globe are vulnerable to a series of potential hazards at different degrees depending on location, altitude above sea level, geomorphological features and socio-economic factors, including demography, human settlement and infrastructural development. Since the 1990s a major effort in developing appropriate methodologies and guidelines to assess coastal vulnerability has been made. Of significant importance, the coast of Gozo embraces both natural and anthropogenic features that occupy a relatively small area. Consequently, coastal vulnerability by multiple coastal hazards is a fact due to the topography of the island, overpopulation in some coastal locations, and intensive coastal development …

Assessing The Potential Benefits Of Learning About Environmental Issues Through A Systems Thinking Pedagogy, Abigail Noble Graefe
Masters Theses, 2010-2019
Systems thinking is a fundamental learning methodology in sustainability education and in some K-12 standards-based education systems in the United States. However, there is little research and practical application on the use of systems thinking in environmental education, especially at the elementary level. This thesis uses a case study on climate change to assess whether a pedagogy based on systems thinking can fulfill learning objectives derived from the Illinois Learning Standards for Science (ILSS) and provide further insights and understandings on the subject being studied. Three learning modules on climate change consisting of systems thinking habits of mind, concepts, and …
Sustainable Agricultural Management And Landscaping Through Agroforestry And Permaculture Case Study: Northern Malta, Shawn Sammy Vella
Sustainable Agricultural Management And Landscaping Through Agroforestry And Permaculture Case Study: Northern Malta, Shawn Sammy Vella
Masters Theses, 2010-2019
The farming industry in Malta is facing severe challenges. Many small patches of arable land are being abandoned following land use conflicts and competition from foreign agricultural products. This reduces the economic capacity of the farming industry which leads to soil erosion and land degradation. On the other hand, the remaining land is being intensively farmed with the use of chemical fertilisers and pesticides. Local government following EU regulations is trying to change this trend by aiming more at promoting a sustainable future for this industry in Malta whilst preserving the natural environments, but still many farmers choose not to …

Instructional Technology and Learning Sciences Faculty Publications
There is a great potential opportunity to use portable physical activity monitoring devices as data collection tools for educational purposes. Using one such device, we designed and implemented a weeklong workshop with high school students to test the utility of such technology. During that intervention, students performed data investigations of physical activity that culminated in the design and implementation of their own studies. In this paper, we explore some of the mathematical thinking that took place through a series of vignettes of a pair of students engaged in analyzing some of their own activity data. A personal connection to the …
Von Willebrand Factor Expression In Vascular Endothelial Cells Of Cage Control And Antiorthostatic Cage Suspension Golden Hamster Ovaries., Kristan Provchy
Von Willebrand Factor Expression In Vascular Endothelial Cells Of Cage Control And Antiorthostatic Cage Suspension Golden Hamster Ovaries., Kristan Provchy
Undergraduate Honors Theses
The hamster estrous cycle lasts four days and is considered to be a physiological model for angiogenesis. Angiogenesis is the formation of new capillaries from preexisting vessels, and it occurs extensively during corpus luteum formation in the estrous cycle. Von Willebrand Factor (vWF) is a glycoprotein that is secreted uniquely in endothelial cells and megakaryocytes. It is frequently used as an endothelial cell marker and it is able to detect vessels within tissues when it is used in immunohistochemical staining techniques. This study explores von Willebrand Factor expression within Golden Hamster ovarian tissue. In particular, this study uses cage control …

Neurochemical Levels Correlate With Population Level Differences In Social Structure And Individual Behavior In The Polyphenic Spider, Anelosimus Studiosus., Jennifer Bryson Price
Electronic Theses and Dissertations
Anelosimus studiosus is a socially polyphenic spider. Individuals can be classified as social/tolerant or solitary/aggressive. These behavioral differences are associated with considerable variation in social structure. Here, we begin to examine the physiological differences that may underlie the behavioral dimorphism in this species and possible implications for the evolution of sociality. Octopamine is a neurotransmitter that has been found to elevate aggression in invertebrates. Serotonin has been shown, in some cases, to interact antagonistically with octopamine. We used High Pressure Liquid Chromatography with Electrochemical Detection to quantify levels of these neurochemicals among adult females from social (multi-female) and solitary (single-female) …
