Size And Density Of Upside-Down Jellyfish, Cassiopea Sp., And Their Impact On Benthic Fluxes In A Caribbean Lagoon, Chester B. Zarnoch, Noshin Hossain, Erika Fusco, Mary Alldred, Timothy J. Hoellein, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

Anthropogenic disturbances may be increasing jellyfish populations globally. Epibenthic jellyfish are ideal organisms for studying this phenomenon due to their sessile lifestyle, broad geographic distribution, and prevalence in near-shore coastal environments. There are few studies, however, that have documented epibenthic jellyfish abundance and measured their impact on ecological processes in tropical ecosystems. In this study, the density and size of the upside-down jellyfish (Cassiopea spp.) were measured in Codrington Lagoon, Barbuda. A sediment core incubation study, with and without Cassiopea, also was performed to determine their impact on benthic oxygen and nutrient fluxes. Densities of Cassiopea were 24–168 …

The Role Of Mesotocin On Social Bonding In Pinyon Jays, Juan Duque, Tanner Rasmussen, Anna Rodriguez, Jeffrey R. Stevens

Jeffrey Stevens Publications

The neuropeptide oxytocin influences mammalian social bonding by facilitating the building and maintenance of parental, sexual, and same‐sex social relationships. However, we do not know whether the function of the avian homologue mesotocin is evolutionarily conserved across birds. While it does influence avian prosocial behavior, mesotocin's role in avian social bonding remains unclear. Here, we investigated whether mesotocin regulates the formation and maintenance of same‐sex social bonding in pinyon jays (Gymnorhinus cyanocephalus), a member of the crow family. We formed squads of four individually housed birds. In the first, “pair‐formation” phase of the experiment, we repeatedly placed pairs …

Testosterone And Interpersonal Attraction: A Placebo-Controlled Design, Stefan M. Goetz

Wayne State University Dissertations

Testosterone has long been implicated as a neuroendocrinological mechanism in the expression of reproductive strategies. Humans the world over form and maintain pair-bonds suggesting that pair-bonds may serve to enhance reproductive fitness. However, infidelity is a perennial threat to these bonds. The data in humans suggests that testosterone is associated with mate-seeking but may be detrimental to relationship maintenance. However, past work has relied on correlational studies and additional findings from nonhuman animal models suggest that acute changes rather than baseline concentrations in testosterone may in fact protect extant pair-bonds. The present research sought to test the causal role of …

Geography

Forests have re-taken centre stage in global conversations about sustainability, climate and biodiversity. Here, we use a horizon scanning approach to identify five large-scale trends that are likely to have substantial medium- and long-term effects on forests and forest livelihoods: forest megadisturbances; changing rural demographics; the rise of the middle-class in low- and middle-income countries; increased availability, access and use of digital technologies; and large-scale infrastructure development. These trends represent human and environmental processes that are exceptionally large in geographical extent and magnitude, and difficult to reverse. They are creating new agricultural and urban frontiers, changing existing rural landscapes and …

Bio-Economic Outcomes Under Alternative Management Strategies With Human Choice And Behavior: Modeling Tautog And Anglers' Preferences, Eric T. Schultz, Zhenshan Chen, Pengfei Liu, Stephen Swallow, Jacob M. Kasper

EEB Articles

Key findings

• There was relatively strong support for slot limits, and roughly comparable support for status quo management, among anglers fishing for Tautog in Long Island Sound.
• Respondents were not in favor of a total moratorium on fishing for Tautog.
• Providing survey respondents information on how different management scenarios will affect fishing in the future had little detectable impact on fishing preferences.
• Respondents expected to fish less in the future if a wide slot limit is imposed or if status quo management is maintained, but expected no change in effort if a narrow slot limit is imposed.
• Changes in regulations …

An Evaluation Of Availability And Adequacy Of Multi-Hazard Early Warning Systems In Asian Countries: A Baseline Study, Ignacio Aguirre-Ayerbe, Maria Merino, Seinn Lei Aye, Ranjith Dissanayake, Fathmath Shadiya, Crisanto M. Lopez

Biology Faculty Publications

Early warning systems are widely considered as one of the more important aspects to reduce the impacts and consequences that hazardous natural events pose to societies. Similar to the other terms related to disaster risk reduction, this concept has evolved over time to eventually result in a comprehensive framework, that includes features from the upstream phase, such as detection and forecasting tools and models, to the downstream phase that considers a people-centred approach.

Based on this holistic conceptual framework, this paper attempts to assess the degree of adequacy and integration of early warning systems with reference to international standards using …

Number Of Shoes Tested During A Running Shoe Mass Perception Task May Not Influence Accuracy, James G. Saxton, Joel G. Greenya, Christopher L. Kliethermes, David S. Senchina

Journal of the Iowa Academy of Science: JIAS

Commercially available running shoes differ in terms of their relative masses. It is unclear how well consumers may be able to judge mass differences from wearing alone, though previous studies suggest that perceptual outcomes may be influenced by experimental design factors such as the length of time worn. The purpose of this study was to investigate how the number of shoes used in a testing session impacts wearers’ mass perceptual accuracy. Forty-eight young adult males ran for 5 min in 4 pairs of shoes (their own running shoes plus 3 unfamiliar pairs) before being asked whether an unfamiliar running shoe …

Novel Mechanism For Turning Performance In Bluefin Tuna, Abigail Downs

West Chester University Master’s Theses

Scombrid fishes can attain exceptional swimming speeds due to their thunniform, lift-based propulsion, large muscle mass, and fusiform body shape. A rigid body restricts maneuverability for aquatic organisms. To test if turning maneuvers by the rigid-bodied Pacific bluefin tuna (Thunnus orientalis) are constrained, captive animals were video recorded from above as the animals routinely swam around a large circular tank or during feeding bouts. The turning performance was classified into three different types of turns: 1) glide turn, where the tuna uses the caudal fin as a rudder to passively move through the turn, 2) powered turn, where …

Remote Sensing Approaches To Predict Forest Characteristics In Northwest Montana, Ryan P. Rock

Graduate Student Theses, Dissertations, & Professional Papers

Remote sensing can be utilized by land management organizations to save money and time. Mapping vegetation using either aerial photographs or satellite imagery and the applications for forest management are of particular interest to the Montana Department of Natural Resources. In 2018, the organization began a pilot program to test the incorporation of raster analysis of remotely sensed data into their inventory program and had limited success. This analysis identified two areas of improvement: the selection method of inventory plots and the imagery used for classification and metrics. This study found that selecting inventory plots using a generalized random tessellation …

"A Pressure Not To Be Resisted Or Evaded": Military Occupation, Reform, And The Incorporation Of Northern Montana, 1879-1916, Hayden Nelson

Graduate Student Theses, Dissertations, & Professional Papers

This thesis explores Fort Assinniboine’s role as an extension of the federal government’s military arm in the Northern Plains. It argues that the military occupation of northern Montana served to incorporate the northern borderland region and peoples into the American mainstream as a part of the national reconstruction processes following the Civil War into the twentieth century. In a period of half a century, north-central Montana transformed from a Native American common hunting ground lacking any major white settlement to a rapidly developing agricultural region. Fort Assinniboine played a central role in this transformation, hastening the economic collapse of the …

In my thesis, I explore how the nomination of the Chumash Heritage National Marine Sanctuary acts as a platform from which Traditional …

Transcriptomic Profiling Of Postmortem Prefrontal Cortex And Nucleus Accumbens From Chronic Alcohol Abusers., Eric S. Vornholt

Theses and Dissertations

Alcohol use disorder (AUD) is a debilitating psychiatric illness that develops from a combination of genetic and environmental factors. While it is well documented that AUD is heritable, the shift from recreational alcohol use to abuse/dependence is poorly understood. In this dissertation, using postmortem brain tissue from individuals with alcohol dependence (AD), we profiled the genome-wide expression of circular RNA (circRNA), microRNA (miRNA), and messenger RNA (mRNA) to better understand the impact of gene expression on the development of AUD. To achieve this, we performed two independent studies that explore transcriptome differences between AD cases and controls. The first of …

Diverse Autonomic Nervous System Stress Response Patterns In Childhood Sensory Modulation, Jacquelyn Christensen, Heather Wild, Erin S. Kenzie, Wayne Wakeland, Deborah Budding, Connie Lillas

Complex Systems Faculty Publications and Presentations

The specific role of the autonomic nervous system (ANS) in emotional and behavioral regulation—particularly in relation to automatic processes—has gained increased attention in the sensory modulation literature. This mini-review article summarizes current knowledge about the role of the ANS in sensory modulation, with a focus on the integrated functions of the ANS and the hypothalamic-pituitary-adrenal (HPA) axis and their measurement. Research from the past decade illustrates that sympathetic and parasympathetic interactions are more complex than previously assumed. Patterns of ANS activation vary across individuals, with distinct physiological response profiles influencing the reactivity underlying automatic behavioral responses. This review article advances …
