Ontogenetic Trait Variation Influences Tree Community Assembly Across Environmental Gradients, Marko J. Spasojevic, Elizabeth A. Yablon, Brad Oberle, Jonathan A. Myers

Biology Faculty Research

Intraspecific trait variation is hypothesized to influence the relative importance of community assembly mechanisms. However, few studies have explicitly considered how intraspecific trait variation among ontogenetic stages influences community assembly across environmental gradients. Because the relative importance of abiotic and biotic assembly mechanisms can differ among ontogenetic stages within and across environments, ontogenetic trait variation may have an important influence on patterns of functional diversity and inferred assembly mechanisms. We tested the hypothesis that variation in functional diversity across a topo-edaphic gradient differs among ontogenetic stages and that these patterns reflect a shift in the relative importance of different assembly …

Blastic Plasmacytoid Dendritic Cell Neoplasm With Extensive Cutaneous And Central Nervous System Involvement, Hayder Saeed, Mukta Awasthi, Abeer Al-Qaisi, Suleiman Massarweh

Internal Medicine Faculty Publications

Blastic plasmacytoid dendritic neoplasm is an exceedingly rare tumor that has undergone several changes in nomenclature over the last two decades, largely because of confusion regarding its cell of origin. It does, however, have distinctive clinical features with a particularly aggressive clinical course and no standard treatment. Overall, prognosis is poor and relapse is routine after initial response to chemotherapy. In this report, we describe a typical patient with this disease and reconcile the available literature and its evolution. We emphasize the leukemic nature of this tumor's behavior, with extensive central nervous system and skin involvement, and describe for the …

Converting Capital: The Experiences Of Latinas/Os In Graduate Health Care Programs, Maristela C. Zell

The Qualitative Report

This qualitative study combines critical race theory, cultural capital theory, and counter-storytelling to examine the experiences of Latina/o in graduate health care programs. Community cultural wealth provided the framework to investigate the mechanisms by which students converted their sociocultural assets into the kinds of social, cultural, and educational capital needed to succeed in a graduate program and pursue their career goals. A qualitative content analysis was employed to interpret participants’ conversion experiences. The forms of community cultural wealth described by Yosso – aspirational, linguistic, familial, navigational, social, and resistant – intersected and interacted with one another. Aspirational and linguistic forms …

Novel Quantitative Macro Biomolecule Analysis Based On A Micro Coulter Counter, Y Han, H. Wu, F. Liu, Gang Cheng, Jiang Zhe

Mechanical Engineering Faculty Research

We demonstrate quantitative biomolecule analysis using a micro coulter counter. Specific binding between antibody functionalized microparticles and target biomolecule cause large aggregates of microparticles. The micro coulter counter was employed to measure aggregation ratio, ratio of the aggregate counts to the total particle counts. Goat anti-rabbit IgG, used as a model biomarker, were tested in this paper. The experiment results showed that the aggregation ratio increases with the increasing biomolecule concentration, and the detectable concentration range from 16 to 160 ng/ml was achieved.

Eocene-Oligocene Latitudinal Climate Gradients In North America Inferred From Stable Isotope Ratios In Perissodactyl Tooth Enamel, Alessandro Zanazzi, Emily Judd, Andrew Fletcher, Harold Bryant, Matthew J. Kohn

Geosciences Faculty Publications and Presentations

The Eocene-Oligocene transition (~ 34 Ma) was one of the most pronounced episodes of climate change of the Cenozoic. In order to investigate this episode of global climate cooling in North America, we analyzed the carbon and oxygen stable isotope composition of the carbonate component of 19 perissodactyl (horse and rhino) tooth enamel samples from the Eocene-Oligocene rocks of the Cypress Hills Formation (southwestern Saskatchewan, Canada); we then compared the results with previously published data from the US Great Plains (Nebraska, South Dakota, and Wyoming).

Average (± 1σ) perissodactyl enamel δ¹³C values (vs. V-PDB) in the Eocene (-8.8 …

Toward A Quantitative Theory Of Food Consumption Choices And Body Weight, Sebastien Buttet, Veronika Dolar

Publications and Research

We propose a calibrated dynamic model of food consumption choices and body weight to study changes in daily caloric intake, weight, and the away-from-home share of calories consumed by adult men and women in the U.S. during the period between 1971 and 2006. Calibration reveals substantial preference heterogeneity between men and women. For example, utility losses stemming from weight gains are ten times greater for women compared to men. Counterfactual experiments show that changes in food prices and household income account for half of the increase in weight of adult men, but only a small fraction of women’s weight. We …

The Relationship Between Hoarding And Distractibility, Julia Y. Carbonella

Open Access Theses

Hoarding is a debilitating disorder that has gained increasing interest in recent years, contributing to its re-classification as a discrete condition. However, much remains unclear about its underlying mechanisms of risk, though evidence implicates information processing deficits. In particular, the domain of inattention has been highlighted in extant clinical and phenomenological studies, though neuropsychological lab tests have produced largely mixed findings. The current study aimed to clarify the nature of attentional deficits by conducting a multi-method investigation, including an eye-tracking task designed to target distractibility, along with a sorting task as a behavioral measure of hoarding. Results indicated that self-reported …

Legume Crops Phylogeny And Genetic Diversity For Science And Breeding, Petr Smýkal, Clarice J. Coyne, Mike J. Ambrose, Nigel Maxted, Hanno Schaefer, Matthew W. Blair

Agricultural and Environmental Sciences Faculty Research

Economically, legumes (Fabaceae) represent the second most important family of crop plants after the grass family, Poaceae. Grain legumes account for 27% of world crop production and provide 33% of the dietary protein consumed by humans, while pasture and forage legumes provide vital part of animal feed. Fabaceae, the third largest family of flowering plants, has traditionally been divided into the following three subfamilies: Caesalpinioideae, Mimosoideae, and Papilionoideae, all together with 800 genera and 20,000 species. The latter subfamily contains most of the major cultivated food and feed crops. Among the grain legumes are some of mankind's earliest crop plants, …

Reproduction Of Endangered Big-Headed Turtle, Platysternon Megacephalum (Reptilia: Testudines: Platysternidae), Yik-Hei Sung, Billy C.H. Hau, Nancy E. Karraker

Natural Resources Science Faculty Publications

The big-headed turtle (Platysternon megacephalum) is heavily harvested to support tremendous demands from food and pet markets, and thus its ecology remains poorly understood. The presence of self-sustaining populations in Hong Kong (22°09’-22°37’N, 113°50’-114°30’E) provides important opportunities to advance our understanding of this species. We employed mark-recapture surveying, radio-tracking of two gravid females, and directed streamside searches to document the reproductive ecology of the species between September 2009 and June 2011 in Hong Kong. We found seven gravid females between 20-27 June 2010 and 2011, and which subsequently oviposited on average three eggs (range 2-8), with mean length …

Differential Expressions Of The Alternatively Spliced Variant Mrnas Of The Μ Opioid Receptor Gene, Oprm1, In Brain Regions Of Four Inbred Mouse Strains, Jin Xu, Zhigang Lu, Mingming Xu, Grace C. Rossi, Benjamin Kest, Amanda R. Waxman, Gavril W. Pasternak, Ying-Xian Pan

Publications and Research

The µ opioid receptor gene, OPRM1, undergoes extensive alternative pre-mRNA splicing in rodents and humans, with dozens of alternatively spliced variants of the OPRM1 gene. The present studies establish a SYBR green quantitative PCR (qPCR) assay to more accurately quantify mouse OPRM1 splice variant mRNAs. Using these qPCR assays, we examined the expression of OPRM1 splice variant mRNAs in selected brain regions of four inbred mouse strains displaying differences in µ opioid-induced tolerance and physical dependence: C56BL/6J, 129P3/J, SJL/J and SWR/J. The complete mRNA expression profiles of the OPRM1 splice variants reveal marked differences of the variant mRNA expression among …

Brief Of Scholars Of The Constitutional Rights Of Children Susannah W. Pollvogt, Catherine E. Smith, And Tanya Washington As Amici Curiae In Support Of Plaintiffs-Appellants And Reversal: Robicheaux V. Caldwell, Catherine E. Smith, Tanya Washington, Susannah W. Pollvogt

Scholarly Articles

Amici are scholars and professors of family law and the law of equal protection. Amici submit this brief to respond directly to arguments advanced by the State of Louisiana that its laws prohibiting same-sex marriage2 are justified because they advance child welfare. Specifically, the State asserts that its laws advance child welfare by promoting Louisiana’s interest in: (1) linking children with their biological parents to prevent the social stigma associated with being “illegitimate” and (2) establishing the child as a member of an intact family resulting from the marriage of the mother and alleged father. These purported justifications express and …

Brominated Flame Retardants, Tetrabromobisphenol A And Hexabromocyclododecane, Activate Mitogen-Activated Protein Kinases (Mapks) In Human Natural Killer Cells, Anita Cato, Lindsay Celada, Esther Caroline Kibakaya, Nadia Simmons, Margaret M. Whalen

Chemistry Faculty Research

Natural killer (NK) cells provide a vital surveillance against virally infected cells, tumor cells, and antibody-coated cells through the release of cytolytic mediators and gamma interferon (IFN-γ). Hexabromocyclododecane (HBCD) is a brominated flame retardant used primarily in expanded (EPS) and extruded (XPS) polystyrene foams for thermal insulation in the building and construction industry. Tetrabromobisphenol A (TBBPA) is used both as a reactive and an additive flame retardant in a variety of materials. HBCD and TBBPA contaminate the environment and are found in human blood samples. In previous studies, we have shown that other environmental contaminants, such as the dibutyltin (DBT) …

Minimal Effects Of An Invasive Flowering Shrub On The Pollinator Community Of Native Forbs, Y Anny Chung, Laura A. Burkle, Tiffany M. Knight

Biology Faculty Research

Biological invasions can strongly influence species interactions such as pollination. Most of the documented effects of exotic plant species on plant-pollinator interactions have been observational studies using single pairs of native and exotic plants, and have focused on dominant exotic plant species. We know little about how exotic plants alter interactions in entire communities of plants and pollinators, especially at low to medium invader densities. In this study, we began to address these gaps by experimentally removing the flowers of a showy invasive shrub, Rosa multiflora, and evaluating its effects on the frequency, richness, and composition of bee visitors to …

Phenomenology, The Spirits Of The Age, And The (Religious) Task Of Philosophy, Neal Deroo

Faculty Work Comprehensive List

The presenter states that philosophy in general—and phenomenology in particular—remain predominantly academic endeavors, done by professional philosophers, to professional philosophers, for professional philosophers and that the key to changing this situation and so to recover the public nature of the phenomenological enterprise is to reconceive the task of philosophy as the 2 discernment of the spirits of the age in which we find ourselves. To do this, he highlights two distinct elements of phenomenological methodology that enable it to perform such a task: first, its epistemological claim that the matters to be investigated must be both taken on their own …

Differences In Speciation Progress In Feather Mites (Analgoidea) Inhabiting The Same Host: The Case Of Zachvatkinia And Alloptes Living On Arctic And Longtailed Skuas, Miroslawa Dabert, Stephen J. Coulson, Dariusz J. Gwiazdowicz, Børge Moe, Sveinn Are Hanssen, Elisabeth M. Biersma, Hanne E. Pilskog, Jacek Dabert

Harold W. Manter Laboratory of Parasitology: Library Materials

Recent molecular phylogenetic analyses have revealed that some apparently oligoxenous feather mite species are in fact monoxenous cryptic species with little morphological differentiation. In this study we analyzed two species, Zachvatkinia isolata (Avenzoariidae) and Alloptes (Sternalloptes) stercorarii (Alloptidae) which prefer different parts of the plumage of two sister species of birds: arctic skua (Stercorarius parasiticus) and long-tailed skua (S. longicaudus) breeding on tundra in the High Arctic archipelago of Svalbard. Given that there are no reports about hybridization events between the host species, we expected that both skuas would have …

Groundwater Controls On Physical And Chemical Processes In Streamside Wetlands And Headwater Streams In The Kenai Peninsula, Alaska, Michael Kroh Callahan

USF Tampa Graduate Theses and Dissertations

For this dissertation I studied groundwater and surface water interactions in the Kenai Lowlands, Alaska. In particular, I examine two important aspects of groundwater and surface water interactions: 1) Groundwater's influence on surface-water temperature; and 2) Groundwater's role in forming hydrologic flow paths that can connect uplands to streamside wetlands and streams. Chapter 2 investigates the controls on stream temperature in salmon-bearing headwater streams in two common hydrogeologic settings: 1) drainage-ways, which are low-gradient streams that flow through broad valleys; and 2) discharge-slopes, which are high gradient streams that flow through narrow valleys. The results from chapter 2 showed significant …

Documentation Of The Black-Footed Ferret, Mustela Nigripes On The Standing Rock Indian Reservation, Mobridge, South Dakota, Michael P. Gutzmer, Jeffrey C. Kelly

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Since 1991, 19 specific black-footed ferret reintroduction projects have been conducted across 8 States, Canada, and Mexico. All five of the first ferret reintroductions (from 1991 to 1996) continue to be occupied by ferrets. The photographs of October 31 and November 1 are the first unequivocal documentation of black-footed ferrets on the Standing Rock Indian Reservation. Ferrets observed on Standing Rock may be dispersals from the nearby Cheyenne River Sioux Indian Reservation to the south. The nearest re-introduction site for ferrets is approximately 20 miles away, in Whitehorse, South Dakota, and the observation of ferrets on Standing Rock could document …
