Feral pigs (Sus scrofa) are considered to be among the world's worst invasive species due to their successful invasion and ecological and economic impact to native and agricultural plants and animals around the world. Feral pigs are significant disturbance agents that destroy plant communities, change soil characteristics, alter nutrient cycling, and create open sites for colonization of both native and non-native plant species through their foraging behavior called rooting.

Show moreFeral pigs (Sus scrofa) are considered to be among the world's worst invasive species due to their successful invasion and ecological and economic impact to native and agricultural plants and animals around the world. Feral pigs are significant disturbance agents that destroy plant communities, change soil characteristics, alter nutrient cycling, and create open sites for colonization of both native and non-native plant species through their foraging behavior called rooting. In contrast to native animal disturbances, rooting is a striking feature in the landscape that varies in space, seasonal timing, frequency (number of times rooted), and intensity (depth of rooting). During this study, feral pigs rooted 7.7% of the search area, which increased to 12% when abandoned patches (baseline patches that were not rooted during this study) were included. Overall, feral pigs rooted and re-rooted habitats along roads and trails significantly more than wetlands. Rooting also varied temporally with the most rooting occurring during July-November, which also corresponds to the peak in rooting intensity. Implications to land managers include avoiding the installation of roads and trails near wet to mesic habitats or other habitats that contain species of concern in order to conserve habitat quality and recreational value. Despite less rooting activity, feral pigs still pose a significant threat to wetlands as evidenced by the large amount of abandoned patches documented. In order to conserve natural areas, effective management and development of efficient control methods is needed to keep feral pig populations in check. As a large opportunistic omnivore, feral pigs have the potential to be important vectors for endozoochorus seed dispersal of a variety of plant species. Feral pigs can travel long distances and have a gut retention time up to 49 hours, therefore seeds can be deposited throughout the landscape far from the parent plant. Over the course of this study, feral pigs dispersed 50 plant species from a wide range of ecological and morphological characteristics, though the majority were native, small seeded, wetland species. For most plant species, location of deposition matched their habitat preference and suggests a high probability of survival. Feral pigs disperse mainly wetland plant species, which has important implications for wetland conservation. However, feral pigs also deposited unwanted species into wetlands and predated the seeds of important wetland canopy tree species.

Policy makers have long recognized the importance of considering past experience, history, and the use of Analogical reasoning when making policy decisions. When elite political actors face foreign policy crises, they often use their past experience, refer to history, and use Analogical reasoning to help them frame their decisions. In the case of the ill-fated invasion of Cuba at the Bay of Pigs, the use of Analogical reasoning revolving around past covert successes may have created an...
Show morePolicy makers have long recognized the importance of considering past experience, history, and the use of Analogical reasoning when making policy decisions. When elite political actors face foreign policy crises, they often use their past experience, refer to history, and use Analogical reasoning to help them frame their decisions. In the case of the ill-fated invasion of Cuba at the Bay of Pigs, the use of Analogical reasoning revolving around past covert successes may have created an environment for faulty foreign policy decision-making. Former members of the Office of Strategic Services (OSS) filled the ranks of the Central Intelligence Agency (CIA) and held key positions within the Eisenhower and Kennedy administrations. OSS success with guerrilla warfare, sabotage, and intelligence gathering during World War II, coupled with early CIA covert successes (specifically in Guatemala), may have led President Kennedy to make the wrong policy decisions with regard to dealing with Fidel Castro and Cuba. This research explores the use of Analogical reasoning during the decision-making process by way of process-tracing. Process-tracing attempts to identify the intervening processes between an independent variable (or variables) and the outcome of the dependent variable. We look at six critical junctures and compare how Groupthink, the Bureaucratic Politics Model, and Analogical reasoning approaches help explain any causal mechanisms. The findings suggest that Analogical reasoning may have played a more significant role in President Kennedy's final decision to invade Cuba than previously thought. The findings further suggest that by using the Analogical reasoning approach, our understanding of President Kennedy's foreign policy in Cuba is enhanced when compared to the Groupthink and Bureaucratic Politics Model approaches emphasized in past research.

The opportunity to enhance the sense of fulfillment necessary in revolutionizing and liberating a person's daily life, regardless of their age, can be found in the manifestation of play. It is through the acknowledgment of instinct, nature, and discovery that play reveals its power.

Show moreThe opportunity to enhance the sense of fulfillment necessary in revolutionizing and liberating a person's daily life, regardless of their age, can be found in the manifestation of play. It is through the acknowledgment of instinct, nature, and discovery that play reveals its power. As a Theatre for the Very Young (TVY) practitioner, I utilize creative play to inspire exploration and innovation among students under the age of six. However, what are the ways in which theatre, specifically TVY, invites all generations of people to experience the power of play? This thesis documents the three-year development of When Pigs Fly, an original TVY experience that encourages audience members of all ages to engage in creative play through sensation, fellowship and discovery. This study explores the collective creation of When Pigs Fly as developed through research, education, and practice. In highlighting the cognitive and emotional benefits of creative play, this study seeks to legitimize TVY as a valued art form, and invites theatre-makers to utilize the research and practice shared to inspire future endeavors that will shape the outlook of TVY throughout the United States.

Despite an abundance of archaeological material recovered from sites in Island Southeast Asia, the timing and route by which cultigens first arrived in Wallacea remains unclear. Many of the staple crops now grown on these islands were domesticated in mainland Asia, and were deliberately introduced by humans at an unknown point during the Holocene, through several possible routes. In this study, the ?13C, ?15N and ?18O values of subfossil bones and teeth attributed to Sus celebensis and Sus...
Show moreDespite an abundance of archaeological material recovered from sites in Island Southeast Asia, the timing and route by which cultigens first arrived in Wallacea remains unclear. Many of the staple crops now grown on these islands were domesticated in mainland Asia, and were deliberately introduced by humans at an unknown point during the Holocene, through several possible routes. In this study, the ?13C, ?15N and ?18O values of subfossil bones and teeth attributed to Sus celebensis and Sus scrofa are analyzed. These materials, which span the last 5160 years at Liang Bua, Flores, Indonesia are used to determine if and when there was a shift towards agricultural intensification, and whether this intensification included the integration of domesticated C4 crops. The ?13C and ?15N values of the bone and dentin collagen samples indicate an abrupt shift towards enrichment in 13C and depletion in 15N at some time between 5160 and 2750 yBP. This hints at changes in human subsistence patterns that may have included the clearing of forests, and the integration of non-endemic C4 cultigens such as foxtail millet (Setaria italica) onto the island. No statistically significant variation in the ?18O values of the enamel carbonate samples over time is observed, suggesting that once they appeared on Flores, semi-domesticated pigs became an important part of the island ecosystem, and were bred and raised on Flores instead of being continuously imported from elsewhere.
