Lianas And Soil Nutrients Predict Fine‐Scale Distribution Of Above‐Ground Biomass In A Tropical Moist Forest, Alicia Ledo, Janine B. Illian, Stefan A. Schnitzer, S. Joseph Wright, James W. Dalling, David F.R.P. Burslem

Biological Sciences Faculty Research and Publications

Summary

1. Prediction of carbon dynamics in response to global climate change requires an understanding of the processes that govern the distribution of carbon stocks. Above‐ground biomass (AGB) in tropical forests is regulated by variation in soil fertility, climate, species composition and topography at regional scales, but the drivers of fine‐scale variation in tropical forest AGB are poorly understood. The factors that control the growth and mortality of individual trees may be obscured by the low resolution of studies at regional scales.
2. In this paper, we evaluated the effects of soil nutrients, topography and liana abundance on the fine‐scale spatial distribution …

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 …

Evidence That The PI Release Event Is The Rate-Limiting Step In The Nitrogenase Catalytic Cycle, Zhi-Yong Yang, Rhesa Ledbetter, Sudipta Shaw, Natasha Pence, Monika Tokmina-Lukaszewska, Brian Eilers, Qingjuan Guo, Nilisha Pokhrel, Valerie L. Cash, Dennis R. Dean, Edwin Antony, Brian Bothner, John W. Peters, Lance C. Seefeldt

Nitrogenase reduction of dinitrogen (N₂) to ammonia (NH₃) involves a sequence of events that occur upon the transient association of the reduced Fe protein containing two ATP molecules with the MoFe protein that includes electron transfer, ATP hydrolysis, P_i release, and dissociation of the oxidized, ADP-containing Fe protein from the reduced MoFe protein. Numerous kinetic studies using the nonphysiological electron donor dithionite have suggested that the rate-limiting step in this reaction cycle is the dissociation of the Fe protein from the MoFe protein. Here, we have established the rate constants for each of the key …

Magnetic Materials For Biomedical Applications, Michael E. Zilm

Doctoral Dissertations

Magnetic materials are of interest for biomedical applications for the ability to remotely control magnetic particles through the use of non-invasive magnetic fields. Specific applications of magnetic materials in biomedical fields include magnetic resonance imaging, drug delivery, and hyperthermia-based cancer treatments. The most commonly used material for these applications are iron oxides, which suffer from acute toxicity and unknown fate in vivo and thereby limit their applications.

An alternative approach is to substitute magnetic ions into a biocompatible and biodegradable material to impart magnetic properties. Hydroxyapatite (HA), the main inorganic component of natural bone, is widely studied as a biomaterial …

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 …

Nanotechnology Applications In Medical Diagnosis, Imaging, And Therapy, Mansoor M. Amiji

Nanotechnology in Medicine: From Molecules to Humans

Tremendous advances in molecular and personalized medicine also present challenges for translation of innovative experimental approaches into clinically relevant strategies. To overcome some of these challenges, nanotechnology offers interesting solutions for disease prevention, diagnosis, and treatment. For many systemic diseases, overcoming biological barriers and target specific delivery are the key challenges. Additionally, newer generation of molecular therapies, such as gene therapy, oligonucleotides, and RNA interference (RNAi) require robust and highly specific intracellular delivery strategies for effective and clinically meaningful therapeutic outcomes.

In this presentation, I will cover several of our approaches for development of multifunctional engineered nano-systems for targeted therapies …

On The Roots Of Media Ecology: A Micro-History And Philosophical Clarification, Corey Anton

Peer Reviewed Articles

This paper provides a brief review of media ecology. It is partly a micro-history of the tradition, and partly a philosophical clarification of how and why “systems-theory orientations,” literacy studies, and the rapid spread of new media were all essential to its germination, growth, and proliferation. Finally, the paper offers concluding remarks regarding social constructionist thought and how it relates to the media ecology tradition.

Positional Challenges And Advantages Of A Phd Student Researching The Phd, Chang Da Wan

The Qualitative Report

It is fairly uncommon for a PhD student to conduct a study that looks at PhD education, and this paper discusses the challenges and advantages of my experience as a PhD student in conducting a PhD research about the PhD. This PhD research project was not an action research or self-reflective of my own educational journey. In this paper, I identify the challenges concerning my position as both a PhD student and a researcher exploring the educational processes of the PhD, and illustrate the ways I adopted to overcome these challenges. I also point out that having addressed these challenges; …

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 …

Influence Of Musical Engagement On Symptoms Of Tourette’S Disorder, William Christopher Brown

USF Tampa Graduate Theses and Dissertations

Tourette’s is currently considered a neurodevelopmental genetic disorder. Georges Gilles de la Tourette is given primary credit for the diagnoses of the disorder in the late 1800s. Clear answers have been elusive although modern research and improvements to neuroimaging have enabled the causal factors of Tourette’s Disorder (TD) to be examined with greater scrutiny. Currently, there is no known cure or pharmaceutical treatment that has been proven 100% effective for all patients and symptoms of Tourette’s. Anecdotally, there have been recent media and self-reports of people diagnosed with Tourette’s finding relief from their symptoms through involvement in focus-based activities such …

The Role Of Collectivism And Spiritual/Religious Coping On Patient And Family Member Functioning In Schizophrenia And The Feasibility Of A Culturally Informed Group Therapy For Schizophrenia, Jessica L. Maura

Open Access Theses

Research suggests that group based psychosocial treatments for schizophrenia provide benefits to patients and family members alike. However, few of these existing treatments consider cultural factors that may enhance their efficacy with diverse populations. The current study examined the potential impact of two cultural constructs, collectivism and spiritual/religious coping on patient and family member functioning in order to assess the relative importance of addressing these constructs in psychosocial treatments for schizophrenia. We first examined whether collectivistic ideals and use of spiritual/religious coping strategies related to psychiatric and psychological functioning among 113 patients and 50 family members of patients with schizophrenia. …

Development Of Biocompatible Small-Molecule Spacers As Metal Oxide Nanoparticles' Stabilizing Agents, Galina Goloverda, Huy Do, Ezinne U. Agwaramgbo, Anastasia Labeaud, Rajesh Komati, Vladimir Kolesnichenko

Nanotechnology in Medicine: From Molecules to Humans

Development and study of the magnetic nanoparticles for biological and clinical applications remains one of the challenging research areas in chemistry and materials science. The performance of these particles as, for example, drug delivery, MRI, hyperthermia or cell tracking agents, depends on their magnetic susceptibility. Their ability to form stable aqueous colloids, the mobility, and diffusion properties in biological media, rely on organic coating, which is usually composed of hydrophilic biocompatible polymers such as dextrans or poly(ethylene glycol)s. Some areas of biomedical imaging, labeling and delivery application can benefit from magnetic nanoparticles with higher mobility and penetration, stronger interaction with …

Iron Oxide Nanoparticles With A Variable Size And An Iron Oxidation State For Imaging Applications, Vladimir Kolesnichenko, Galina Goloverda, Pavel Kucheryavy, Leonard Spinu

Nanotechnology in Medicine: From Molecules to Humans

Magnetite nanoparticles in the size range of 3.2-7.5 nm were synthesized with high yields under variable reaction conditions using high temperature hydrolysis of the precursor iron(II) and iron(III) chelated alkoxide complexes in surfactant-free diethylene glycol solutions. The average sizes of the particles were adjusted by changing the reaction temperature and time, and by using sequential growth technique. Reaction products formed as shelf-stable colloids. In order to obtain γ‑iron(III) oxide particles in the same range of sizes, diethylene glycol colloids of magnetite were oxygenated at room temperature. As-obtained colloids were characterized by DLS; powdery products obtained by coagulating them with oleic …

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 …

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 …

Found Object/Readymade Art In The Treatment Of Trauma And Loss, Michal Bat Or, Orna Megides

Journal of Clinical Art Therapy

Found object/readymade art is a familiar expressive medium in art therapy that has been insufficiently explored. The present article theoretically and clinically examines Found object/readymade art as a progressive therapeutic intervention in the treatment of trauma and loss. It aims to show how creating found object/readymade art enables the client to encounter and contain damaged/disconnected memories and provides a space for integrating and meaning-making in the face of rupture and loss. This is discussed through a review of found object/readymade art medium in the history of art and in art therapy and by phenomenological observation of its creating process. Specific …

Commentary: What It Means To Be A Citizen, Allen C. Guelzo

Civil War Era Studies Faculty Publications

It was one of the great shocks of my life, and it came early. In fifth-grade government class. Though I can't remember much else that we learned then, a detail in Article 1, Section 2, of the Constitution reached out and grabbed me like the hound of the Baskervilles: "No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President."

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 …
