Understanding Emotional Suffering, Barbara J. King

Animal Sentience

In responding to insightful commentaries from 7 scholars, for which I am grateful, I offer new thoughts on whether animals can conceptualize and express signs of grief. I also discuss why I included both weak and strong examples of animal mourning, and how this work may help us think about enhanced welfare for animals, including freedom from emotional suffering.

Sea Turtle Response To Climate Change: Analyzing Current And Predicting Future Impacts On Populations, Habitat, And Prey Populations, Eva J. Golden

Honors Theses and Capstones

With the prediction of devastating global climate change effects for the near future, scientists are expanding their research and understanding of some of the most severely affected organisms. Because sea turtles rely on both marine and terrestrial habitats for survival, and because coastal areas are already experiencing great losses due to sea level rising, human development, and pollution, all seven species are already listed as threatened under the Endangered Species Act. In this literature analysis, I examined the many factors that contribute to a sampling of the current sea turtle population status as well as scrutinized turtle adaptability to the …

Predicting The Impact Of Future Climate On Ecologically Important Macroalgae, Charlie Phelps

Theses: Doctorates and Masters

Macroalgae play an important role in coastal reef systems and are often referred to as ecosystem engineers. They serve as primary producers, supporting a diverse range of organisms, and are a sink for atmospheric CO2. Water acidification and ocean warming caused by anthropogenic activities are affecting many marine flora and fauna, potentially impacting the physical and chemical performance of macroalgae and the consumption rates of associated herbivores. Many studies have focused on ocean acidification or ocean warming individually but there is an overall lack of research investigating the combined effects and the ensuing repercussions on consumer-prey relationships.

Examining Sociological Differences And The Influence Of Prey Distribution And Environmental Variability In The Distribution Of A Top Marine Predator, The Bottlenose Dolphin (Tursiops Truncatus), Stefanie K. Gazda

Graduate Doctoral Dissertations

The purpose of this dissertation was to examine the influence of environmental variability on the distribution of prey, and the influence of prey spatial structure and habitat variability may have on the distributions of bottlenose dolphins (Tursiops truncatus). Additionally I examined how sociological differences (behavior type and the changes in a foraging behavior specific to Cedar Key Florida) influences the relative roles of bottlenose dolphins within the population.

The Gowans et al. scheme assumes that small groups form small communities and that foraging groups are small and rare as there are few foraging benefits to promote grouping. Using network analysis, …

Characterizing The Role Of Sialylated Milk Glycans And The Infant Gut Microbiota In Growth And Metabolism, Mark Richard Charbonneau

Arts & Sciences Graduate Student Theses and Dissertations

Undernutrition is a pressing and pervasive global health problem. The pathogenesis of this disease remains unclear, but epidemiologic studies indicate that it is not due to food insecurity alone. Moreover, current therapeutic interventions have limited efficacy in preventing or ameliorating the long-term sequelae of undernutrition, including stunting and cognitive deficits. Recent culture-independent studies have demonstrated that the normal postnatal pattern of gut microbiota development is disrupted in children with undernutrition, leading to the proposal that perturbations in gut microbiota development impairs healthy growth of the host. Human breast milk contains a diverse repertoire of free and conjugated human milk oligosaccharides …

Plant Toxins Influence Diet Selection And Intestinal Parasites In A Specialist Herbivore, Marcella Rene Fremgen

Boise State University Theses and Dissertations

Herbivores select plants and patches that generally maximize nutrient intake and minimize intake of plant secondary metabolites (PSMs). Protein is important for growth, reproduction and maintenance, but maximizing intake of protein is often limited by concentrations of PSMs that are potentially toxic to herbivores and energetically expensive to process. However, the consequences of ingesting PSM are often dose-dependent. At high doses, PSMs generally have negative physiological effects and are avoided, but some PSMs can be therapeutic against parasites at low doses and could therefore be selected. We used Greater Sage-grouse (Centrocercus urophasianus, hereafter, sage-grouse) to test how PSMs influence …

Assessing The Sociocultural Impact Of Special Events In The Context Of Germanfest In Nebraska, Usa, Yanli Wang

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

The present study examined the sociocultural impact of special events based on the cultural festival of GermanFest in Syracuse, Nebraska. A total of 143 (71.5%) local residents responded to the self-administered survey. The dimensions of the sociocultural impact, the important reasons for celebrating the festival, the relationship among festival stakeholders, the levels of community involvement, and the improvement of the quality of life in the community as impacts of the festival and demographic information were investigated separately.

The Festival Social Impact Attitude Scale (FSIAS) was utilized to identify the dimensions of the sociocultural impact of GermanFest. Three dimensions were identified …

Diversification And Speciation Across Sundaland And The Philippines: The Effects Of 30 Million Years Of Eustatic Flux, Luke J. Welton

Theses and Dissertations

I highlight two squamate lineages endemic to Southeast Asia, the Asian water monitors (Varanus salvator Complex) and the Angle-headed lizards (Agamidae: Gonocephalus), and elucidate their systematic affinities and historical biogeography. My results represent novel phylogenetic inferences, with biogeographic histories and diversification events corresponding to major climatic fluctuations over the past 30 million years. Additionally, I solidify the taxonomy and systematics of the Varanus salvator Complex, and enumerate more than a dozen Gonocephalus lineages as candidate species in need of taxonomic scrutiny. Lastly, I investigate contemporary and historical patterns of dispersal throughout Sundaland, and between Sundaland and the Philippines.

Thomas, Matthew J. Collins, Cecil M. Lewis Jr., Corinne Hofman, Christina Warinner

Biology Faculty Articles

To date, characterization of ancient oral (dental calculus) and gut (coprolite) microbiota has been primarily accomplished through a metataxonomic approach involving targeted amplification of one or more variable regions in the 16S rRNA gene. Specifically, the V3 region (E. coli341–534) of this gene has been suggested as an excellent candidate for ancient DNA amplification and microbial community reconstruction. However, in practice this metataxonomic approach often produces highly skewed taxonomic frequency data. In this study, we use non-targeted (shotgun metagenomics) sequencing methods to better understand skewed microbial profiles observed in four ancient dental calculus specimens previously analyzed by amplicon …

Identifying Humanized Ecosystems: Anthropogenic Impacts, Intentionality, And Resource Acquisition At Crystal River (8ci1) And Roberts Island (8ci41), Charles Trevor Duke

USF Tampa Graduate Theses and Dissertations

The impact of human activity on ecosystems is an issue at the forefront of global concern. Marine ecosystems are a particular concern, given their importance for human sustenance. Through the removal of species that are highly susceptible to the effects of overfishing, global fisheries have been driven to near collapse in recent decades. The long-term effects of such practices has resulted in declines in mean trophic level of aggregate fish catches over time, as well as decreasing diversity of species available for regular harvest (Jackson et al. 2001; Pauly et al. 1998). These supposedly “modern” problems have been recently identified …

Veganism As An Aspiration, Lori Gruen, Robert C. Jones

Dietary Choice and Foods of Animal Origin Collection

iven the violence, objectification, domination, commodification, and oppression inherent in industrialized food production, some conscientious consumers have adopted vegan practices. This chapter discusses two conceptions of veganism, lifestyle/identity veganism, VI, and veganism as a goal/aspiration, VA. It argues that due to conceptual and practical flaws with VI, conscientious consumers should adopt VA. It considers and rejects the so-called compassionate carnivore movement. It then explores arguments denying the casual efficacy of adopting any form of veganism. It concludes that VA can make a difference, and those in consumer cultures are obligated to adopt and practice it.

Wildlife Crime And Other Challenges To Resource System Resilience, Patricia Anne Raxter

Graduate Program in International Studies Theses & Dissertations

Although wildlife crime has exploded in Africa over the past decade —“commercial poaching” now kills an estimated eight percent of the continent’s elephant population each year—some governments have proven more successful than others at protecting wildlife and preserving habitats. To explain this variation, this study examines how the policies of three states (Kenya, Tanzania, and Botswana) have enhanced or undermined the resilience of the continent’s elephant ecosystem. Using the social-ecological system framework, the study illustrates how each state’s changing practices have either exacerbated the stresses wrought by wildlife crime or successfully protected local populations from poaching. The study finds that …

Homo naledi is a previously-unknown species of extinct hominin discovered within the Dinaledi Chamber of the Rising Star cave system, Cradle of Humankind, South Africa. This species is characterized by body mass and stature similar to small-bodied human populations but a small endocranial volume similar to australopiths. Cranial morphology of H. naledi is unique, but most similar to early Homo species including Homo erectus, Homo habilis or Homo rudolfensis. While primitive, the dentition is generally small and simple in occlusal morphology. H. naledi has humanlike manipulatory adaptations of the hand and wrist. It also exhibits a humanlike foot …

Familiar Face Detection In 180ms, Matteo Visconti Di Oleggio Castello, M. Ida Gobbini

Dartmouth Scholarship

The visual system is tuned for rapid detection of faces, with the fastest choice saccade to a face at 100ms. Familiar faces have a more robust representation than do unfamiliar faces, and are detected faster in the absence of awareness and with reduced attentional resources. Faces of family and close friends become familiar over a protracted period involving learning the unique visual appearance, including a view-invariant representation, as well as person knowledge. We investigated the effect of personal familiarity on the earliest stages of face processing by using a saccadic-choice task to measure how fast familiar face detection can happen. …

Large Wildlife Removal Drives Immune Defence Increases In Rodents, Hillary S. Young, Rodolfo Dirzo, Kristofer M. Helgen, Douglas J. Mccauley, Charles L. Nunn, Paul Snyder, Kari E. Veblen, Serena Zhao, Vanessa O. Ezenwa

Wildland Resources Faculty Publications

1. Anthropogenic disturbances involving land use change, climate disruption, pollution and invasive species have been shown to impact immune function of wild animals. These immune changes have direct impacts on the fitness of impacted animals and, also, potentially indirect effects on other species and on ecological processes, notably involving the spread of infectious disease. Here, we investigate whether the selective loss of large wildlife can also drive changes in immune function of other consumer species.
2. Using a long-standing large-scale exclosure experiment in East Africa, we investigated the effects of selective removal of large wildlife on multiple measures of immune function in …

Paleoepidemiology Of Intestinal Parasites And Lice In Pre-Columbian South America *, Adauto Araujo, Karl J. Reinhard, Daniela Leles, Luciana Sianto, Alena Iniguez, Martin Fugassa, Berrnardo Arriaza, Nancy Orellana, Luiz Fernando Ferreira

Karl Reinhard Publications

Some human parasites originated in prehominid ancestors in Africa. Nematode species, such as Enterobius vermicularis (pinworm), hookworms and Trichuris trichiura are shared by humans and other close phylogenetic primates (Pan and Gorilla), showing that they infected a common ancestor to this group. When humans migrated from Africa to other continents they carried these parasites wherever climate conditions allowed parasite transmission from host to host. Other parasites, however, were acquired throughout human biological and social evolutive history when new territories were occupied. Paleoparasitology data is a valuable source to recover emergence and disappearance of parasite infections through analysis of archaeological remains. …

Diet And Parasitism At Dust Devil Cave, Karl J. Reinhard, J Richard Ambler, Magdalene Mcguffie

Karl Reinhard Publications

Human parasitism has obvious relationships to group size and composition, mobility, subsistence patterns, and rates of culture change. At their best, human endoparasites may be annoying; at their worst, some can cause death. Thus, an overall view of the parasite load of a prehistoric population can yield insights useful in interpreting past lifeways. With these thoughts in mind, we undertook a study of Desha Complex (6800-4800 B .C.) human feces recovered from Dust Devil Cave in southern Utah.

Forensic Autopsy. The Particularities Of Consent For Research, Sorin Hostiuc

Journal of Health Ethics

Forensic autopsy has as its main goal to find out the truth about the causes and circumstances of death, when there is a reasonable suspicion to be caused by a violent act. As the legal guardian cannot refuse a forensic autopsy, the forensic physician is free to perform any procedures considered to be necessary for finding out the truth (in order to answer to the objectives asked by the authority). However the use of biological samples or data in research is limited and needs an additional consent, from the legal guardian, which can lead to difficulties in the interpretation of …
