Medical Populism And Covid-19 Testing, Kristin Hedges, Gideon Lasco Apr 2021

Medical Populism And Covid-19 Testing, Kristin Hedges, Gideon Lasco

Development Studies Faculty Publications

This paper uses the lens of medical populism to analyze the impact of biocommunicability on COVID-19 testing through a case study approach. The political efficacy of testing is traced through two mini-case studies: the Philippines and the United States. The case studies follow the approach of populism scholars in drawing from various sources that ‘render the populist style visible’ from the tweets and press releases of government officials to media reportage. Using the framework of medical populism, the case studies pay attention to the ways in which coronavirus testing figured in (1) simplification of the pandemic; (2) spectacularization of the …

Detection Of European Aspen (Populus Tremula L.) Based On An Unmanned Aerial Vehicle Approach In Boreal Forests, Anton Kuzmin, Lauri Korhonen, Sonja Kivinen, Pekka Hurskainen, Pasi Korpelainen, Topi Tanhuanpää, Matti Maltamo, Petteri Vihervaara, Timo Kumpula

Aspen Bibliography

European aspen (Populus tremula L.) is a keystone species for biodiversity of boreal forests. Large-diameter aspens maintain the diversity of hundreds of species, many of which are threatened in Fennoscandia. Due to a low economic value and relatively sparse and scattered occurrence of aspen in boreal forests, there is a lack of information of the spatial and temporal distribution of aspen, which hampers efficient planning and implementation of sustainable forest management practices and conservation efforts. Our objective was to assess identification of European aspen at the individual tree level in a southern boreal forest using high-resolution photogrammetric point cloud …

The Tree Cover And Temperature Disparity In Us Urbanized Areas: Quantifying The Association With Income Across 5,723 Communities, Robert I. Mcdonald, Tanushree Biswas, Cedilla Sachar, Ian Housman, Timothy M. Boucher, Deborah Balk, David Nowak, Erica Spotswood, Charlotte K. Stanley, Stefan Leyk

Publications and Research

Urban tree cover provides benefits to human health and well-being, but previous studies suggest that tree cover is often inequitably distributed. Here, we use National Agriculture Imagery Program digital ortho photographs to survey the tree cover inequality for Census blocks in US large urbanized areas, home to 167 million people across 5,723 municipalities and other Census-designated places. We compared tree cover to summer land surface temperature, as measured using Landsat imagery. In 92% of the urbanized areas surveyed, low-income blocks have less tree cover than high-income blocks. On average, low-income blocks have 15.2% less tree cover and are 1.5˚C hotter …

Prescribed Fire Alters Structure And Composition Of A Mid-Atlantic Oak Forest Up To Eight Years After Burning, Cody L. Dems, Alan H. Taylor, Erica A. H. Smithwick, Jesse K. Kreye, Margot W. Kaye Apr 2021

Prescribed Fire Alters Structure And Composition Of A Mid-Atlantic Oak Forest Up To Eight Years After Burning, Cody L. Dems, Alan H. Taylor, Erica A. H. Smithwick, Jesse K. Kreye, Margot W. Kaye

Aspen Bibliography

Background

Prescribed fire in Eastern deciduous forests has been understudied relative to other regions in the United States. In Pennsylvania, USA, prescribed fire use has increased more than five-fold since 2009, yet forest response has not been extensively studied. Due to variations in forest composition and the feedback between vegetation and fire, Pennsylvania deciduous forests may burn and respond differently than forests across the eastern US. We measured changes in forest structure and composition up to eight years after prescribed fire in a hardwood forest of the Ridge and Valley region of the Appalachian Mountains in central Pennsylvania.

Geography Faculty Publications

Accurate phenological information is essential for monitoring crop development, predicting crop yield, and enhancing resilience to cope with climate change. This study employed a curve-change-based dynamic threshold approach on NDVI (Normalized Differential Vegetation Index) time series to detect the planting and harvesting dates for corn and soybean in Kentucky, a typical climatic transition zone, from 2000 to 2018. We compared satellite-based estimates with ground observations and performed trend analyses of crop phenological stages over the study period to analyze their relationships with climate change and crop yields. Our results showed that corn and soybean planting dates were delayed by 0.01 …

Evidence is accumulating that evolutionary changes are not only common during biological invasions but may also contribute directly to invasion success. The genomic basis of such changes is still largely unexplored. Yet, understanding the genomic response to invasion may help to predict the conditions under which invasiveness can be enhanced or suppressed. Here, we characterized the genome response of the spotted wing drosophila Drosophila suzukii during the worldwide invasion of this pest insect species, by conducting a genome-wide association study to identify genes involved in adaptive processes during invasion. Genomic data from 22 population samples were analyzed to detect genetic …

The MALINA oceanographic campaign was conducted during summer 2009 to investigate the carbon stocks and the processes controlling the carbon fluxes in the Mackenzie River estuary and the Beaufort Sea. During the campaign, an extensive suite of physical, chemical and biological variables were measured across seven shelf-basin transects (south-north) to capture the meridional gradient between the estuary and the open ocean. Key variables such as temperature, absolute salinity, radiance, irradiance, nutrient concentrations, chlorophyll a concentration, bacteria, phytoplankton and zooplankton abundance and taxonomy, and carbon stocks and fluxes were routinely measured onboard the Canadian research icebreaker CCGS Amundsen and from a …


Artisanal And Aboriginal Subsistence Whaling In Saint Vincent And The Grenadines (Eastern Caribbean): History, Catch Characteristics, And Needs For Research And Management, Russell Fielding, Jeremy J. Kiszka Apr 2021

Artisanal And Aboriginal Subsistence Whaling In Saint Vincent And The Grenadines (Eastern Caribbean): History, Catch Characteristics, And Needs For Research And Management, Russell Fielding, Jeremy J. Kiszka

Honors College Faculty Publications

Whaling has been a contentious international environmental issue for decades and carries complex ecological and socioeconomic implications. In Saint Vincent and the Grenadines (SVG), a small archipelagic nation located in the Eastern Caribbean, present-day whaling traces its origin to local interaction with American-based whalers during the nineteenth and early twentieth centuries. When American whaling in the region ceased, local shore-based whaling arose to fill the niche and to exploit the remaining, though diminished, stocks of large whales, as well as stocks of small cetaceans that the American whalers had not targeted as heavily. After a period of expansion throughout the …

Buitrago-Bitar, Andrés J. Cortés, Felipe López-Hernández, Jorge M. Londoño-Caicedo, Jaime E. Muñoz-Florez, L. Carmenza Muñoz, Matthew Wohlgemuth Blair

Agricultural and Environmental Sciences Faculty Research

Some of the major impacts of climate change are expected in regions where drought stress is already an issue. Grain legumes are generally drought susceptible. However, tepary bean and its wild relatives within Phaseolus acutifolius or P. parvifolius are from arid areas between Mexico and the United States. Therefore, we hypothesize that these bean accessions have diversity signals indicative of adaptation to drought at key candidate genes such as: Asr2, Dreb2B, and ERECTA. By sequencing alleles of these genes and comparing to estimates of drought tolerance indices from climate data for the collection site of geo-referenced, tepary bean accessions, we …


Illegal Wildlife Trade Increases Probability Of Zoonotic Disease Spread In The United States, Ryan Bushman Apr 2021

Illegal Wildlife Trade Increases Probability Of Zoonotic Disease Spread In The United States, Ryan Bushman

Student Research Symposium

Illegal wildlife trade is a major contributor to the spread of zoonotic disease in the United States and may potentially lead to further public health emergencies, a significant loss of life, and can cost billions of dollars. The trade of bushmeat and exotic pets are examples of illegal wildlife trade that can result in the spread of zoonotic diseases. These illegal activities are driven by deep-rooted cultural beliefs, financial necessity, and luxurious lifestyles. An analysis of the existing literature on these subjects through the lens of anticipatory intelligence reveals certain areas of the current systems that combat illegal wildlife trade …

Otto Warburg And His Contributions To The Screw Pine Family (Pandanaceae), Martin W. Callmander, Robert Vogt, Anna Donatelli, Sven Buerki, Chiara Nepi

Biology Faculty Publications and Presentations

Otto Warburg (1859–1938) had a great interest in tropical botany. He travelled in South-East Asia and the South Pacific between 1885 and 1889 and brought back a considerable collection of plant specimens from this expedition later donated to the Royal Botanical Museum in Berlin. Warburg published the first comprehensive monograph on the family Pandanaceae in 1900 in the third issue of Das Pflanzenreich established and edited by Adolf Engler (1844–1930). The aim of this article is to clarify the taxonomy, nomenclature and typification of Warburg's contributions to the Pandanaceae. Considerable parts of Warburg's original material was destroyed in Berlin …

Calibration Chain Transformation Improves The Comparability Of Organic Hydrogen And Oxygen Stable Isotope Data, Sarah Magozzi, Clement P. Bataille, Keith A. Hobson, Michael B. Wunder, John D. Howa, Andrea Contina, Hannah B. Vander Zanden, Gabriel J. Bowen

School of Integrative Biological & Chemical Sciences Faculty Publications

  1. Stable hydrogen and oxygen isotopic compositions (δ2H and δ18O, respectively) of animal tissues have been used to infer geographical origin or mobility based on the premise that the isotopic composition of tissue is systematically related to that of local water sources. Isotopic data for known-origin samples are required to quantify these tissue–environment relationships. Although many of such data have been published and could be reused by researchers, differences in the standards used for calibration and analytical procedures for different datasets limit the comparability of these data.
  2. We develop an algorithm that uses results from comparative analysis of secondary standards to …


Male-Biased Dispersal In A Fungus-Gardening Ant Symbiosis, Alix E. Matthews, Katrin Kellner, Jon N. Seal Apr 2021

Male-Biased Dispersal In A Fungus-Gardening Ant Symbiosis, Alix E. Matthews, Katrin Kellner, Jon N. Seal

Biology Faculty Publications and Presentations

For nearly all organisms, dispersal is a fundamental life-history trait that can shape their ecology and evolution. Variation in dispersal capabilities within a species exists and can influence population genetic structure and ecological interactions. In fungus-gardening (attine) ants, co-dispersal of ants and mutualistic fungi is crucial to the success of this obligate symbiosis. Female-biased dispersal (and gene flow) may be favored in attines because virgin queens carry the responsibility of dispersing the fungi, but a paucity of research has made this conclusion difficult. Here, we investigate dispersal of the fungus-gardening ant Trachymyrmex septentrionalis using a combination of maternally (mitochondrial DNA) …


A Macro Analysis Of Illegal Hunting And Fishing Across Texas Counties: Using An Economic Structural Approach, Leo J. Genco Jr. Apr 2021

A Macro Analysis Of Illegal Hunting And Fishing Across Texas Counties: Using An Economic Structural Approach, Leo J. Genco Jr.

USF Tampa Graduate Theses and Dissertations

The purpose of this disseration is to examine the distribution of illegal hunting and fishing violations across Texas counties in respect to the economic structure. Illegal hunting plays a part in the extraction of resources that are overly withdrawn, and criminologists have ignored this form of deviancy that has large ramifications for the environment. To view this criminal phenomenon, the study uses the Treadmill of Production theory to determine economic structural factors and whether those factors explain the distribution of illegal hunting and fishing. Using regression analyses and SatScan, the findings suggested that while there are significant factors related to …


Determinants Of Discretionary Agricultural Policy Adoption: The Case Of The Livestock Friendly County Program In Nebraska, Cicely Batie Apr 2021

Determinants Of Discretionary Agricultural Policy Adoption: The Case Of The Livestock Friendly County Program In Nebraska, Cicely Batie

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This study analyzes the voluntary approach to agriculture promotion programs through the lens of the Nebraska Livestock Friendly County (LFC) Program. In 2003, the Nebraska Department of Agriculture (NDA) launched the LFC program to bolster the livestock sector in participating counties. The program is unique because of its voluntary nature and targeted agricultural promotion efforts. The NDA designates counties as “Livestock Friendly,” and assists them in streamlining approval processes for livestock feeding operations. This thesis examines why a program like LFC is necessary, the patterns of its adoption across Nebraska, and finally, its impact on the livestock sector of participating …
