Gastrointestinal Helminths Of Two Species Of Mouse Opossums (Marmosa Demerarae And Marmosa Murina) From French Guiana, Beth Byles, Francois Catzeflis, R Philip Scheibel, Agustin Jimenez-Ruiz

Publications

The woolly mouse opossum Marmosa demerarae and the murine opossum, Marmosa murina, occur in sympatry across most of their range; however, they are not syntopic in that M. demerarae is more abundant in the canopy of primary and secondary forest, while M. murina is scansorial and appears to be more abundant in lower forest strata. We herein present a survey and comparison of the helminths occurring in these 2 species in French Guiana based on examinations of 18 individuals of M. murina and 21 individuals of M. demerarae. At the level of the component community, species richness was …

Duck Productivity In Restored Species-Rich Native And Species-Poor Non-Native Plantings, Ryan Haffele, Michael E. Eichholz, Cami S. Dixon

Publications

Conservation efforts to increase duck production have led the United States Fish and Wildlife Service to restore grasslands with multi-species (3-5) mixtures of introduced cool season vegetation often termed dense nesting cover (DNC). The effectiveness of DNC to increase duck production has been variable, and maintenance of the cover type is expensive. In an effort to decrease the financial and ecological costs (increased carbon emissions from plowing and reseeding) of maintaining DNC and provide a long-term, resilient cover that will support a diversity of grassland fauna, restoration of multi-species (16-32) plantings of native plants has been explored. We investigated the …

The Effects Of Testosterone On Leydig Cell Development In Male Yhr+ Mice, Steven D. Ebers

Honors Theses

Leydig cells (LC) are specialized cells in the testis that develop during puberty and are responsible for producing testosterone. Luteinizing Hormone (LH) and testosterone are important for LC development. Binding of LH to its receptor (LHR) initiates the production of testosterone. Constitutively active mutations in LHR have been identified in humans resulting in puberty in males as young as 3 or 4 years of age. A transgenic mouse (YHR⁺), was generated which mimics the constitutively active LHR by fusing the hormone, human chorionic gonadotropin, to LHR to continually activate the receptor. Testosterone levels in YHR⁺ mice are …

The Acquisition Of The Nongeneric Uses Of The English Definite Article The By Arabic Speakers Of English, Aied M. Alenizi

Theses

This study aimed to investigate the acquisition of the four non-generic uses of the English definite article the by Arabic learners of English in Saudi Arabia. These non-generic uses included textual, situational, cultural and structural. This study had three goals: (1) to determine whether these uses are acquired in a certain sequence; (2) to explore which one of these uses is the most difficult and the easiest in learning; (3) to investigate whether one or two of the uses are overused.

The instrument consisted of 59 sentences adopted from Liu and Gleason (2002). There were 40 instances for required uses …

Climate Change, Shifts In Tropical Storm Regimes And Triadica Sebifera Invasion In Coastal Mississippi, United States, Shishir Paudel

Dissertations

Global climate change is predicted to affect timing and severity of disturbance events (e.g., fire, drought, hurricanes, wind storms, and inundation), but the extent of these disturbance events and their impacts on natural ecosystems may vary regionally. Rising sea level, increased frequency and intensity of tropical storms, and altered inundation regimes are likely to create changing environmental conditions in low-lying coastal ecosystems. These large scale disturbances may increase resource availability and regeneration spaces, reduce competition, and possibly increase community vulnerability to invasion. Shifting disturbance regimes and invasion together are predicted to drive long-term shifts in coastal plant community structure and …

Factors Influencing The Spatial And Temporal Structure Of A Carnivore Guild In The Central Hardwood Region, Damon B. Lesmeister

Dissertations

Ecological communities are most commonly structured by a mixture of bottom-up processes such as habitat or prey, competition within the same trophic level, and top-down forces from higher trophic levels. Carnivore guilds play a vital role in the broader ecological community by stabilizing or destabilizing food webs. Consequently, factors influencing the structure of carnivore guilds can be critical to patterns in ecosystems. Coyotes (Canis latrans), bobcats (Lynx rufus), gray foxes (Urocyon cinereoargenteus), raccoons (Procyon lotor), red foxes (Vulpes vulpes), and striped skunks (Mephitis mephitis) occur sympatrically throughout much of their geographic ranges in North America and overlap in resource use, …

The Impact Of Daycare And Child Temperament On Parent-Child Interactions, Kyle Bersted

Theses

This study explored the potential impact of child temperament and daycare on behavior problems and parental sensitivity. It was expected that children with more "difficult" temperaments would exhibit more behavior problems and have less sensitive parents when experiencing high amounts of daycare. Measures from 60 families involved in the Southern Illinois Twins and Siblings Study (SITSS) were examined. Results indicated that highly active children exhibited more externalizing behaviors when experiencing less daycare. Shy children experiencing more daycare had more sensitive parents. Additionally, a temperamental difference between co-twins was related to differential parental sensitivity. Lastly, DZ co-twins were more temperamentally different …

Identifying Environment Of Origin Of Illinois River Asian Carp Via Otolith Microchemistry And Stable Isotope Analyses, Jacob Dylan Norman

Theses

Asian carp have rapidly expanded their range through much of the Mississippi River Drainage over the past 10 to 15 years. Silver and bighead carp are now the dominant fish species present along several reaches of the Illinois River. The upper Illinois River and shipping canals entering Lake Michigan are of great concern as pathways for Asian carp to enter the Great Lakes. Knowledge of reproductive habitats and dispersal pathways for these species may be valuable for ongoing and future efforts to control these exotic invasives. Previous studies have successfully identified spawning areas of native riverine species via otolith microchemistry, …

Trade Liberalization And Agricultural Growth In Haiti, Elsie Despeignes

Theses

Liberalization has been, for the past three decades, one of the most prominent strategies used in the developing world to promote growth and foster development. Haiti, as many other least developed countries, has implemented the liberalization policies over the past two decades. The poor socioeconomic conditions of the Haitians, today, have pushed to question the effectiveness of the neoliberal plan. Agriculture being a pivotal sector of the Haitian economy, the study goal is the evaluation of liberalization on the agricultural production. The findings are that trade liberalization is detrimental to agriculture in Haiti. The food crops production, a major component …

Estimation Of Optimal Protein To Energy Ratio And Percent Soybean Meal Replacement Of Fish Meal In Juvenile Scaphirhynchus Sturgeon Diets, Elliott C. Kittel

Theses

Research developing artificial propagation, husbandry, and nutrition of sturgeon species has developed greatly since the collapse of the Caspian Sea fisheries in the 1980s. Sturgeon species are commercially prized for their unfertilized roe which is marketed as the delicacy, caviar. Sturgeon production units commonly utilize commercial salmonid feeds, which contain large proportions of fish meal (FM) and fish oil (FO). Concerns regarding economics and sustainability have put pressure on aquafeed manufactures to efficiently utilize FM and FO, and to incorporate alternative protein sources, such as soybean meal (SBM). Therefore, the present studies estimated the optimal protein:energy ratio of juvenile Pallid …

Country Women: Back-To-The-Land Feminism And Radical Feminist Praxis In The Women's Liberation Movement, Jessica Louise Lynn

Theses

AN ABSTRACT OF THE THESIS OF JESSICA LOUISE LYNN, for the Master of Arts degree in HISTORY, presented on March 25, 2013, at Southern Illinois University Carbondale. TITLE: COUNTRY WOMEN: BACK-TO-THE-LAND FEMINISM AND RADICAL FEMINIST PRAXIS IN THE WOMEN'S LIBERATION MOVEMENT MAJOR PROFESSOR: Dr. Robbie Lieberman Historians of American History, cultural movements, the 60s-era, and even the counterculture frequently categorize second-wave feminism as a monolithic movement, its complexity minimized, its successes devalued. While there are a handful of feminist historians who have offered in depth, corrective histories to the popular narrative of the 60s-era, still missing from the historiography of …

The Effect Of Injury Severity On Behavioral Tasks Used For The Assessment Of Cognitive Functioning Following Traumatic Brain Injury, Kris M. Martens

Dissertations

Cognitive impairment is the most frequent cause of disability in humans following traumatic brain injury (TBI), yet the behavioral tasks used to assess cognitive behavior in rodent models of brain injury are underrepresented in the field. Additionally, few of these tasks have been used to assess behavior across degrees of injury severity. The goal of the present study was to compare four behavioral tasks commonly used in the field in frontally-injured rats with both mild and moderate-to-severe brain injuries. At the start of the study, rats were assigned to two of the following behavioral tasks: Dig scent discrimination (Dig) task, …

Shifting Legitimating Accounts In A Changing Institutional Field: An Analysis Of The Organic Food Industry, 1990-2011, Michael J. Sheridan

Dissertations

In this study, we argue the organic industry's move towards a more legal definition of organic production indicated a shift in the legitimating criteria in the organic agriculture institutional field, which can be observed through the analysis of the legitimating accounts of various actors. Prior to USDA certification, institutional actors in the organic food field largely relied upon the norms and values of its participants to maintain order. Legitimacy was based on the perception that a firm embodied a certain value set, which typically included opposition to large-scale commercial operations (DeLind, 2000; Drinkwater, 2009). To some, the introduction of federal …

The Effects Of Propagule Source, Soil Amendment, And Stock Type On The Survival And Growth Of Giant Cane (Arundinaria Gigantea (Walt.) Muhl.) Established As A Low Maintenance Nursery, David Dalzotto

Theses

Giant cane [Arundinaria gigantea (Walter) Muhl.] is a native bamboo species that was once widely distributed within bottomland forests and as extensive monotypic stands (canebrakes) along waterways of the southeastern United States. Land conversion to agriculture greatly decreased the distribution of canebrakes. Limited to less than two percent of its historic range, canebrakes are now considered an endangered ecosystem. A 0.24 hectare low maintenance experimental nursery of giant cane was established at Southern Illinois University to examine the effect of planting stock type, soil amendments, and four collection sources on cane survival and growth (number of culms, height and diameter …

Forage Quality Of Andropogon Gerardii Across A Precipitation Gradient, Juliette Donatelli

Theses

This study focused on the ecotypic variation in forage quality of Andropogon gerardii Vitman, a dominant C4 grass in North American grasslands and an important forage grass for native and introduced grazers. Ecotypes are genetic variations of a plant species adapted to local environmental conditions. Andropogon gerardii is represented by many local ecotypes across its range. Forage quality analyses quantify digestibility and nutrition of a plant sample and allow an assessment of nutritional value for grazers. The variability in forage quality among A. gerardii ecotypes is unknown. This study aimed to quantify variation in forage quality of A. gerardii collected …
