Identifying The Effects Of Land Use And Policy On Disturbance Regimes In The Teanaway Community Forest, Washington, Savannah Bommarito

All Master's Theses

The historic fire regime of the forests of the Eastern Cascades, Washington, has been described as one of high-frequency, low-severity fires using fire scar analysis. Over the past few centuries, the historically open, park-like ponderosa pine-dominated stands have been significantly altered due to Euro-American land use change such as fire exclusion, grazing, mining, and logging. The eventual encroachment of shade-tolerant species has resulted in a high-density forest structure that promotes rare, but extreme fire behavior and heightened susceptibility to insect attacks. As a result, the current disturbance regime is significantly less frequent and of higher severity, posing risks to forest …

Gorilla-Visitor Interface At A Zoo Exhibit: Positioning Effects Of Western Lowland Gorillas (Gorilla Gorilla Gorilla) And Zoo Visitors, Alan Bergman

All Master's Theses

Zoos have missions to provide high-quality care for their animals and an enjoyable and educational experience for visitors. Looking at the animal-visitor interface can allow zoos to evaluate their success in these efforts and to build upon what they have already accomplished. The present study was conducted to investigate the relationship between visitors and gorillas in a zoo environment. The effect of gorilla proximity to visitor viewing areas on visitor attentiveness was examined in indoor and outdoor gorilla exhibits. Visitor experience surveys were collected from visitors exiting the outdoor exhibit. Stepwise multiple regressions revealed group and individual gorilla proximity effects …

A Cognitive Task As Enrichment For Chimpanzees (Pan Troglodytes) In Sanctuary, Federico Rubio

All Master's Theses

Chimpanzees (Pan troglodytes) hold an especially powerful attraction for researchers interested in cognition and how it developed to the degree observed in humans specifically and primates more generally. Chimpanzees are behaviorally complex primates with compelling data supporting their possession of intricate internal lives. The objective of this study was to simultaneously learn more of the cognitive process of inductive reasoning while also assessing the efficacy of a computerized box as a novel form of enrichment to aid in improving the environment of captive chimpanzees. Three social groups at the retired medical research chimpanzee sanctuary Project Chimps were given …

Water And Life. A Cross-Sectional Study On Determinants Of Beverage Consumption And Water Access In One Tribal Community, Christina White

All Master's Theses

Increasingly, poor diet has been shown to be one of the most crucial factors associated with cause of death, even more critical than smoking. Research in the past two decades has consistently linked increased consumption of sugar-sweetened beverages (SSB) to the obesity epidemic contributing to a public health crisis all over the United States. Native Americans, among other minority groups, suffer obesity disproportionately from the rest of the US population, yet they continually fail to be included in research on the subject. Traditional research methods, sparse care coverage on reservations, consolidation of unique tribes into one classification, and failure to …

Seasonal Soil Carbon Fluxes In Transitioning Agricultural Soils In Central Washington State: Relations To Land-Use, Environmental Factors And Soil Carbon-Nitrogen Characteristics, Brandon Kautzman

All Master's Theses

Changing agricultural land-use practices to increase soil carbon sequestration contributes to climate change mitigation and improved food security by moving CO₂ from the atmosphere into soil as soil organic carbon (SOC). In 2016, a farm in Thorp, Washington, Spoon Full Farm, began converting land historically farmed using conventional methods of tillage and synthetic fertilizers to conservation farming methods with direct seeding and organic soil amendments with a goal of sequestering carbon in the soil. This project evaluates relationships of soil CO₂ respiration and net ecological exchange (NEE) with land-use types, seasonal environmental factors (air temperature, relative humidity, soil …

Are Highways Stressful For Pikas?: Analysis Of Stress Hormones Of The American Pika (Ochotona Princeps) Living Adjacent To Interstate 90 In The Cascade Range Of Washington State, Thomas J. Mcintyre Iii

All Master's Theses

Roads often disrupt ecosystem connectivity, harming many wildlife populations. Wildlife crossing structures perforate the barrier-effect of roads, providing safe passage for species dispersing across roads, thereby reconnecting ecosystems. Some wildlife species live in modified habitats along roads and in habitat features within wildlife crossing structures, but their fitness in these potentially stressful environments is poorly understood. Chronic stress alters behavior, reduces reproduction, and has been linked to reduced survival. Animals affected by chronic stress in road-adjacent habitats could reduce the ability of wildlife crossing structures to improve connectivity across roads. I assessed stress hormone concentrations in a low-mobility species, the …

Transgenerational Plasticity Is Sex-Dependent And Persistent In Yellow Moneyflower (Mimulus Guttatus), Kayla Akkerman

All Master's Theses

Transgenerational phenotypic plasticity, whereby environmental cues experienced by parents alter the phenotype of their progeny, has now been documented in diverse organisms. Transmission of environmentally determined responses is known to occur through both maternal and paternal gametes, but the underlying mechanisms have rarely been compared. In addition, the persistence of induction over multiple generations appears to vary widely but has been characterized for relatively few systems. Yellow monkeyflower (Mimulus guttatus) is known to exhibit transgenerational induction of increased glandular trichome production in response to simulated insect damage. Here we test for differences between maternal and paternal transmission of …

Investigating Potential Multi-Protein Complexes Involving Emx2, Nicole Enger

All Master's Theses

The neocortex of the mammalian brain is allocated into specialized areas during embryonic development. In mice, as well as humans, the neocortex develops four primary areas: somatosensory, auditory, visual, and motor. In the adult neocortex, the boundaries between these four areas are marked by differences in cellular architecture and gene expression patterns. However, these physical boundaries are not evident during embryonic development of this structure. Rather, the neocortex initially appears uniform across its expanse, with one exception: a handful of proteins that regulate neocortical arealization are generated in gradients across the expanse of the neocortex and control the size of …

Mapping And Reconstructing The Paleotsunami Record In Queule, South-Central Chile, Pedro I. Matos Llavona

All Master's Theses

Records of past tsunamis help constrain the long-term characteristics of megathrust earthquakes and elucidate the role of sea-level in the preservation of tsunami deposits. Near Queule, south-central Chile (39.3˚S, 73.2˚W), three sand layers interpreted as tsunami deposits are interbedded with dark, organic-rich, silt deposits along a tidal channel landward of a sand spit capped by eolian sand dunes. The uppermost sand layer is attributed to the tsunami from the Mw 9.5 1960 earthquake. The sand layer is widespread, tabular, oxidized, thins landward, and generally occurs at a depth of <20 cm. The spatial distribution of the deposit corresponds closely with the extent of the 1960 tsunami sand on 1961 aerial photographs. We computed numerical simulations of the 1960 tsunami in Queule using the GeoClaw finite-slip hydrodynamic model based on three published earthquake sources. The simulations showed inundation up to 4km inland that overtopped the coastal dunes; agreeing with historical documentation and testimonies of 1960 tsunami survivors. Stratigraphically below the 1960 tsunami deposit are two tabular, landward-thinning sand layers with sharp lower contacts above silty organic-rich layers. Combined radiocarbon ages of seeds, charcoal and wood fragments found at the contacts with the underlying organic layers yielded ages of 5460-5320 and 5990-5910 cal. years BP. These sand layers have similar distribution patterns to the 1960 sand layer, but are finer grained, thinner and less oxidized. Below this sequence of interbedded tsunami sands and silty organic layers there is an abrupt contact underlain by a distinct sequence of four inorganic silt layers alternating with dark brown organic-rich silts, which are older than 6280-6110 cal. years BP. The deepest studied layer is a thick, fine, gray sand. We interpret the gray sand as a submarine environment during the mid-Holocene sea-level high stand, and the alternating inorganic and organic silts as tidal to shallow sub-tidal environments, possibly indicating co-seismic land-level changes. Gradual sea level fall after the deposition of the two paleotsunami sand deposits that changed the geomorphology of the coast and limited the accommodation space necessary to preserve additional overwash sediments could explain the 5000-year hiatus with no evidence of earthquakes or tsunamis. Further research will offer possible explanations for the exception of the 1960 tsunami in breaking this long-term pattern.

Rock Imagery: A Cultural Landscape Analysis In The Yakima Uplands, Jessica Eliana Delgado-Morris

All Master's Theses

This thesis evaluates the history of rock imagery documentation and the ways it can be improved moving forward. This study also explores the potentials of using viewshed analysis to examine the cultural landscape. The documentation and locational analysis support recommendations for future study and protection of rock image sites. There are currently twelve known rock imagery sites at the Joint Base Lewis-McChord - Yakima Training Center (YTC). Most of these sites have not been assessed for changes in integrity or damages in over twenty years. Prior documentation efforts have produced site forms with varying degrees of accuracy and completeness. During …

Holocene Periods Of Aggradation And Incision, Hanson Creek, Washington, Levi Earl Windingstad

All Master's Theses

The causes and timing of cycles of aggradation and incision in the Hanson Creek drainage in central Washington provide insight into changes in channel morphology and paleoenvironment within the region over the last 8000 years. Stratigraphically and spatially coincident archaeological evidence reveals information related to human occupation during the latter half of the epoch. Using LiDAR imagery and field surveys, recent processes such as degree of modern channel incision, accumulation of valley floor sediment, channel morphology and gradient were evaluated. The spatial distribution of these channel characteristics was assessed in relation to proximal landforms such as colluvial deposits, basalt outcrops, …

On The Sentience Of Sheep And Other Useful Objects, Ila France Porcher

Animal Sentience

The nature of sheep has been in plain view ever since the animals were domesticated about 10,000 years ago. Why their intelligence, individuality, and emotional complexity has been ignored is a question that goes well beyond Marino & Merskin’s timely target article. Not only has cognitive bias in favour of religious ideas in biology been involved, but the territorial nature of our own species is implicated as well. The tendency of Homo sapiens to see others in terms of “us” and “them” has resulted in a history of racism, speciesism, and general domination of any others that could be fitted …

Domestication And Cognitive Complexity, David R. Brodbeck, Madeleine I. R. Brodbeck, Keeghan Rosso

Animal Sentience

Marino and Merskin (2019) list a number of tasks that sheep can perform well. As comparative psychologists, we are not surprised by these results. Indeed, many domesticated animal species show similar abilities.

Our Ambivalent Stereotypes Of Sheep, Veronica Sevillano

Animal Sentience

Marino & Merskin’s target article contrasts our ambivalent social ideas about sheep with the empirical evidence of their complex capacities, particularly cognitive ones. To extend our understanding of human-sheep relations, I discuss human social perception of animals and structural variables that predict our stereotypes.

Can A Mirror Capture The Self?, Cynthia Willett

Animal Sentience

Is the mirror a reliable indicator of self-awareness for any species, whether sheep or human? Taking a cue from feminist, phenomenological, and cross-cultural philosophy, a relational self rather than a reflective one might better capture what is at stake for the lives of social animals and for science.

Why Factual Appeals About The Abilities Of Sheep May Fail, Sarah Gradidge, Magdalena Zawisza

Animal Sentience

Marino & Merskin (2019) express hope that providing people with positive information about the abilities of sheep (factual appeals) will improve perceptions of them and thus improve their welfare. However, these factual appeals can, and do, fail to change perceptions of animals. This commentary considers why and when factual appeals fail, and with whom they may be effective.

The Subaltern As Surrogate: Identity And Gender In Contemporary Postcolonial Novels, Jackson T. Turner

College of Graduate Studies: Theses & Dissertations

The Postcolonial novel attempts to reveal the crimes and lasting effects of colonization. By looking at Season of Migration to the North by Tayeb Salih, The English Patient by Michael Ondaatje, and The Reluctant Fundamentalist by Mohsin Hamid, I intend to reveal how the inversion of the typical postcolonial gender dynamic changes the conversation about the relationship between the colonizer and the colonized. The male, colonized characters within these works are used as surrogates for something that the colonizer, female has lost or desires. This change in relationship draws attention to the way in which past empires still exert their …

Are Octopuses Special? Mind, Sociality And Life History, Phyllis C. Lee

Animal Sentience

Understanding the Umwelt or being-ness of an octopus is a fascinating problem. Mather’s review provides us with significant insights into the ways of living of non-humans that exploit a perceptual and physical world we can only guess at. Octopus “distributed minds” call into question our primate-based understandings of the importance of sociality and the pace of life in the evolution of complex perceptual and behavioural abilities.

Cephalopod Molluscs, Causal Models, And Curious Minds, Andrew W. Corcoran

Animal Sentience

Mather (2019) presents a compelling case in favour of octopus mind. Surveying an impressive array of empirical literature, she identifies the creature’s playful, inquisitive behaviour as emblematic of a distinctively mental form of agency. I offer an alternative perspective in which curiosity and play are construed as constitutive processes in the emergence of the (predictive) mind.

The Octopus Mind: Implications For Cognitive Science, Sidney Carls-Diamante

Animal Sentience

Mather consolidates the case for octopus mind and how it may be structured, shifting the starting point of inquiry from “If octopuses had minds, what would they be like?” to “What is the mind of an octopus like?”.

The Octopus Mind And The Argument Against Farming It, Jennifer Jacquet, Becca Franks, Peter Godfrey-Smith

Animal Sentience

Mather is convincing about octopuses having ‘a controlling mind, motivated to gather information,’ but stops short of asking what having that mind means for octopus moral standing. One consequence of understanding the octopus mind should be a refusal to subject octopuses to mass production. Octopus farming is in an experimental phase and supported by various countries. We argue that it is unethical because of concerns about animal welfare as well as environmental impacts.

Introduction: Property In Ecology, Jonathan Adler

Faculty Publications

The papers in this volume explore the further potential for property-based institutions to preserve environmental values and enhance environmental protection. Through case studies, empirical assessments, and consideration of the institutional constraints that may alternatively facilitate or hamper private conservation efforts, these papers deepen our understanding of the institutional context in which conservation occurs and the potential for property-based approaches to supplement, if not supplant, traditional government management of natural resources and environmental regulation. Together, they aim to enhance the conservation potential of property institutions by looking at how such institutions may be extended and defended so as to maximize property’s …

Examining The Effects Of Fadrozole, An Aromatase Inhibitor, On Testosterone And Estrogen Production Of Domestic Chicken Embryos (Gallus Gallus), Abby E. Joseph

Honors Theses

The hypothalamic-pituitary-gonadal (HPG) axis is responsible for the production of the hormones testosterone and estradiol, and testosterone is thought to contribute to regulation of the axis through a negative feedback mechanism. Regulation by negative feedback involves the product of a pathway turning off that pathway when enough product is made. However, because the enzyme P450 aromatase converts testosterone to estradiol, estradiol may also contribute to regulation of the HPG axis and other phenomena that have been attributed to testosterone, like the inhibition of immune function. Previous studies have injected birds with an aromatase inhibitor (presumably reducing estradiol production) and shown …

A Comparative Analysis Of Counterhegemonic Environmental-Economic Projects In Latin America And The United States, Dominic Scicchitano

Honors Theses

The objective of this study is to perform a comparative analysis of counterhegemonic environmental-economic projects in the United States and in Latin America. The work builds on research that I conducted throughout my time at Bucknell University concerning a site known as Better Farm, which distinguishes itself as “a 65-acre sustainability campus, artists' colony, animal sanctuary, and organic farm” located in Redwood, New York (www.betterfarm.org). Better Farm functions as a locus for the surrounding community of roughly 700 residents, connecting a variety of persons interested in both formal sustainability education and informal systems whereby community members support each …

Late Devonian Sedimentary Record Of Appalachian Tectonics And Erosion: Geochronology And Geochemistry Of Detrital Muscovite And Zircon From Central Pennsylvania Strata, Cole T. Gardner

Honors Theses

Foreland basin sediment deposition in North-Central Pennsylvania during Late Devonian time records erosion of hinterland source terranes exhumed during regional plate convergence, including the collisional Acadian orogeny. The Catskill clastic wedge preserves a coarsening-upwards stratigraphic succession from marine to fluvial environments associated with sediment progradation and sea-level regression, yet depositional timescales and quantitative provenance data are largely unconstrained.

Detailed facies analysis of eight outcrops spanning >2 km of stratigraphy in Lycoming Co., Pennsylvania documents distinct upsection changes, interpreted to reflect changes in depositional environments consistent with previous sedimentology of the Catskill clastic wedge. Stratigraphy displays a transition from nearshore marine …
