Ode To Ehrlich And Raven Or How Herbivorous Insects Might Drive Plant Speciation, Robert Marquis, Diego Salazar, Christina Baer, Jason Reinhardt, Galen Priest, Kirk Barnett

Biology Department Faculty Works

Fifty years ago, Ehrlich and Raven proposed that insect herbivores have driven much of plant speciation, particularly at tropical latitudes. There have been no explicit tests of their hypotheses. Indeed there were no proposed mechanisms either at the time or since by which herbivores might generate new plant species. Here we outline two main classes of mechanisms, prezygotic and postzygotic, with a number of scenarios in each by which herbivore‐driven changes in host plant secondary chemistry might lead to new plant lineage production. The former apply mainly to a sympatric model of speciation while the latter apply to a parapatric …

“It’S Just Too Sad!”: Teacher Candidates’ Emotional Resistance To Picture Books, Aimee Papola-Ellis

Reading Horizons: A Journal of Literacy and Language Arts

The use of critical literacy with children’s books that focus on social issues and disrupt the status quo can be a powerful way to create spaces for conversations with students about social justice and empowerment. Teacher candidates in a semester long children’s literature course were asked to respond to a range of children’s texts that dealt with many social issues and disrupted the commonplace. Despite an explicit emphasis on critical literacy and social justice, the candidates were very resistant to using many of the texts in their own future classrooms. They had strong emotional reactions that prevented them from consideration …

Choice And Rigor: Achieving A Balance In Middle School Reading/Language Arts Classrooms In The Era Of The Common Core, Nancy L. Stevens

Reading Horizons: A Journal of Literacy and Language Arts

While the advantages of reading workshops are well known (Atwell, 1998), there is currently a debate among scholars, practitioners, and politicians about the use of instructional/independent level texts in light of the Common Core Standards’ end-of-year requirement for students to be reading at grade level (National Governors Association Center for Best Practices & Council of Chief State School Officers, 2010). Particularly in middle school, where motivation to read often declines, a workshop approach can help students develop and strengthen their interest in reading. A classroom survey completed by middle school students in a suburban school district in the Midwestern United …

Physicochemical And Functional Properties Of Extruded Sorghum‐Based Bean Analog, Akinbode A. Adedeji, Michael V. Joseph, Brian Platter, Sajid Alavi

Biosystems and Agricultural Engineering Faculty Publications

The objective of this study was to develop and evaluate the physicochemical and functional properties of a bean like product made from cold extrusion of sorghum, soy and wheat flours. Formulated samples comprised of sorghum (25–70%), wheat (0–35%) and soy (30–50%) flours. The degree of gelatinization ranged from 54.1 to 93.6%. Pasting curves showed minimal starch damage with peak and final viscosities in the range of 456.0–1138.5 and 297–584 cP, respectively. Textural properties of the extrudates were significantly impacted by starch content and cooking time. There was significant cooking loss due to poor binding properties of the extrudates. Cooking the …

Methylation Of The Leukocyte Glucocorticoid Receptor Gene Promoter In Adults: Associations With Early Adversity And Depressive, Anxiety And Substance-Use Disorders, A. R. Tyrka, S H. Parade, E S. Welch, K. K. Ridout, L Price, C Marsit, L Carpenter

Dartmouth Scholarship

Early adversity increases risk for developing psychopathology. Epigenetic modification of stress reactivity genes is a likely mechanism contributing to this risk. The glucocorticoid receptor (GR) gene is of particular interest because of the regulatory role of the GR in hypothalamic–pituitary–adrenal (HPA) axis function. Mounting evidence suggests that early adversity is associated with GR promoter methylation and gene expression. Few studies have examined links between GR promoter methylation and psychopathology, and findings to date have been mixed. Healthy adult participants (N = 340) who were free of psychotropic medications reported on their childhood experiences of maltreatment and parental death and desertion. …

The Applicability Of Criminology To Terrorism Studies: An Exploratory Study Of Isis Supporters In The United States, Amanda Marie Sharp Parker

USF Tampa Graduate Theses and Dissertations

In the years following the 11 September 2001 attacks, research in the area of terrorism expanded exponentially. However, the changing nature of terrorism and lack of available data make it a difficult topic for criminologists to study; as academics we do not have access to the governmental data and data that is publicly available is often restricted due to the sensitive nature of national security issues. As first hand data is not available, an alternate data source, court records, may provide insight to the profile of current terrorists/terrorist supporters in the United States. Using court data from 71 cases of …

A Minor Necessity: Minor Splicing Is Required In Murine Limb Development, Christopher D. Lemoine

Master's Theses

Microcephalic osteodysplastic primordial dwarfism type-1 (MODI) is a rare congenital developmental disorder resulting in patients presenting with microcephaly, limb abnormalities, and growth retardation. This disease, along with the related Roifman Syndrome, results from mutations to the gene RNU4atac. This gene encodes for the U4atac small nuclear RNA (snRNA) which, along with four other snRNAs (U11, U12, U5, and U6atac) compose the small nuclear ribonucleoprotein (snRNP) complex called the minor spliceosome. Responsible for the excision of a subpopulation of introns (called minor introns), the minor spliceosome is known to play an essential role in eukaryotic limb development. However, while mutations in …

“Black Americans And Hiv/Aids In Popular Media” Conforming To The Politics Of Respectability, Alisha Lynn Menzies

USF Tampa Graduate Theses and Dissertations

This dissertation examines narratives about racialized gender, sexuality, and class through media images of black Americans with HIV/AIDS. Through textual analysis of media sites featuring HIV/AIDS and blackness (The Announcement, Precious, and Marvelyn Brown’s website, www.marvelynbrown.com), this project analyzes how the politics of respectability—a set of precepts that govern how black men and women can present themselves in public spaces to align with white ideals of gender and sexuality—construct black people in media representations of HIV/AIDS. This work examines how respectability politics deployed in media representations of HIV/AIDS and black Americans reclaim notions of acceptable black sexuality …

From Facultative To Obligatory Parental Care: Interspecific Variation In Offspring Dependency On Post-Hatching Care In Burying Beetles, Alexandra Capodeanu-Nägler, Eva M. Keppner, Manfred Ayasse, Heiko Vogel, Anne-Katrin Eggert, Scott K. Sakaluk, Sandra Steiger

Faculty Publications – Biological Sciences

Studies on the evolution of parental care have focused primarily on the costs and benefits of parental care and the life-history attributes that favour it. However, once care evolves, offspring in some taxa appear to become increasingly dependent on their parents. Although offspring dependency is a central theme in family life, the evolutionary dynamics leading to it are not fully understood. Beetles of the genus Nicrophorus are well known for their elaborate biparental care, including provisioning of their young. By manipulating the occurrence of pre- or post-hatching care, we show that the offspring of three burying beetle species, N. orbicollis …

Geospatial Modeling Approach To Monument Construction Using Michigan From A.D. 1000–1600 As A Case Study, Meghan L. Howey, Michael W. Palace, Crystal H. Mcmichael

Faculty Publications

Building monuments was one way that past societies reconfigured their landscapes in response to shifting social and ecological factors. Understanding the connections between those factors and monument construction is critical, especially when multiple types of monuments were constructed across the same landscape. Geospatial technologies enable past cultural activities and environmental variables to be examined together at large scales. Many geospatial modeling approaches, however, are not designed for presence-only (occurrence) data, which can be limiting given that many archaeological site records are presence only. We use maximum entropy modeling (MaxEnt), which works with presence-only data, to predict the distribution of monuments …

A Scoping Study Investigating Student Perceptions Towards Inquiry Based Learning In The Laboratory, N King, Der Touw T Van, L Spowart, C Lawlor

School of Biomedical Sciences

There has been an increasing movement towards the introduction of inquiry based learning in undergraduate physiology laboratories. Students can however find it challenging when there is a sudden transition from traditional didactic practicals to full inquiry based activities. One reason for this could be the students' perceptions about the introduction of inquiry based learning. The aim of this preliminary scoping investigation was to judge students' attitudes towards inquiry based learning following a practical containing an element of inquiry. Students were supplied with approximately 2.5cm gastrointestinal ileal loops from guinea pigs which they connected via a force transducer to recording equipment. …

High Resting Metabolic Rate Among Amazonian Forager-Horticulturalists Experiencing High Pathogen Burden, Michael Gurven, Benjamin C. Trumble, Jonathan Stieglitz, Gandhi Yetish, Daniel Cummings, Aaron D. Blackwell, Bret Beheim, Hillard Kaplan, Herman Pontzer

ESI Publications

Objectives—Resting metabolic rate (RMR) reflects energetic costs of homeostasis and accounts for 60-75% of total energy expenditure (TEE). Lean mass and physical activity account for much RMR variability, but the impact of prolonged immune activation from infection on human RMR is unclear in naturalistic settings. We evaluate the effects of infection on mass-corrected RMR among Bolivian forager-horticulturalists, and assess whether RMR declines more slowly with age than in hygienic sedentary populations, as might be expected if older adults experience high pathogen burden.

Materials and Methods—RMR was measured by indirect calorimetry (Fitmate MED, Cosmed) in 1,300 adults aged 20-90 …

Alone In The Crowd: Appropriated Text And Subjectivity In The Work Of Rirkrit Tiravanija, Liz Linden

Faculty Publications

The practice of Thai artist Rirkrit Tiravanija is perhaps the best-known exemplar of relational aesthetics, a distinction first made by Nicholas Bourriaud and affirmed in the writings of many subsequent art critics; but the critical focus on the interactive aspect of his works has tended to rely on utopian modes of community engagement, which ignore Tiravanija's strategic deployment of relational, interactive structures to implicate the viewer, publicly, in problematic political positions. Tiravanija commonly uses appropriation in his artworks as a way of exposing viewer's biases and this paper focuses specifically on his use of appropriated text to explore divided subjectivities …

A Caenorhabditis Elegans Model To Detect Developmental Teratogens With Adverse Reproductive And Metabolic Effects, Alexis Ann Killeen

USF Tampa Graduate Theses and Dissertations

Obesity is a current epidemic in the United States. Greater than one third of adults and nearly one fifth of children are classified as obese (Ogden, 2014). Increased awareness of this problem has triggered interest into the potentially causal agents in our environment. These agents, termed obesogens, are a type of teratogen hypothesized to work during embryonic development by programming offspring to store excess fat. A type of teratogen, obesogens are also typically reprotoxic, affecting germline development and embryonic viability. These noxious teratogens span a variety of different chemical classes including estrogen mimics, metals and metalloids, biocides, and even voluntary …

Article Iii Standing For Private Plaintiffs Challenging Greenhouse Gas Regulations, Bradford C. Mank

San Diego Law Review

An important unresolved question is whether non-state plaintiffs have standing under Article III of the U.S. Constitution to sue in federal courts in climate change cases. In Massachusetts v. EPA, the Supreme Court held a state government could sue the U.S. government to address climate change issues, and suggested, but did not decide, that private litigants might have lesser rights than states. In Washington Environmental Council v. Bellon, the Ninth Circuit held that private groups did not have standing to challenge Washington State’s failure to regulate greenhouse gas (GHG) emissions from five oil refineries, and implied that private plaintiffs may …

This paper presents an overview of national trends in visual art-making and art sharing using digital media, and, the authors’ reflections on the implications of these findings for art therapy practice. These findings were based on a secondary analysis of the 2012 Survey of Public Participation in the Arts administered by the National Endowment for the Arts. Survey findings indicated that increasing proportions of people in the United States are using digital media for creating, archiving, and sharing their art. Reflections by the authors on these findings include support for increase in use of digital media by art therapists for …

Dialectical Tensions Experienced During Pediatric Chronic Illness: Analyzing Art Therapy Conversations From A Relational Dialectics Perspective, Katherine A. Rafferty, Erin Parcell

Journal of Clinical Art Therapy

Relational dialectics theory (RDT) provides a framework for understanding the dialectical tensions families experience when talking about pediatric chronic illness. One place where families may express these tensions is during clinical art therapy sessions, where therapists encourage child patients and their family members to use the creative process of art to tell stories while engaged in art making. Subsequently, we studied one clinical art therapy program for families with chronically ill hospitalized children. We examined the naturally occurring conversations during the art making process. Family members’ talk enumerated three primary dialectical tensions describing the pediatric illness experience. Findings and implications …

The Effect Of Post-Resistance Exercise Amino Acids On Plasma Mcp-1 And Ccr2 Expression, Adam J. Wells, Jay R. Hoffman, Adam R. Jajtner, Alyssa N. Varanoske

Trichinella Spiralis: Adaptation And Parasitism, Dante Zarlenga, Zhengyuan Wang, Makedonka Mitreva

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Publication of the genome from the clade I organism, Trichinella spiralis, has provided us an avenue to address more holistic problems in parasitology; namely the processes of adaptation and the evolution of parasitism. Parasitism among nematodes has evolved in multiple, independent events. Deciphering processes that drive species diversity and adaptation are keys to understanding parasitism and advancing control strategies. Studies have been put forth on morphological and physiological aspects of parasitism and adaptation in nematodes; however, data is now coming available to investigate adaptation, host switching and parasitism at the genomic level. Herein we compare proteomic data from the clade …
