Manuscripts, Articles, Book Chapters and Other Papers
Urbanization produces spatially variable landscapes where climatic, environmental, and social systems interact in complex ways that affect public health. Environmental exposure along with the associated health risks are unevenly distributed and communities of color are often disproportionately affected by poor health outcomes. Acute pediatric asthma is the most common chronic condition of childhood in developed nations and is especially prevalent in minority and low-income children. In this study, we analyze the spatial variability of neighborhood-level acute pediatric asthma emergency department (ED) visits across the Kansas City Metro Area. Using Bayesian negative binomial regression, we describe the relationships and interactions between …

Biodiversity is essential for maintaining ecosystem balance and functionality, providing vital services such as climate regulation. The rapid decline in biodiversity, driven by habitat loss, habitat fragmentation, and climate change, poses significant threats to ecosystems. Climate change, in particular, is fundamentally altering habitats, leading to shifts in species distributions. However, existing research often lacks decomposed contribution analyses, particularly spatially, for a changing individual environmental attributes when modeling species distribution as an aggregate result of all factors and their interactions. Such analyses are crucial for identifying climate refugia and prioritizing conservation efforts. Taking endangered mammal species as an example, this study …

Working In Pairs Increases Consistency Of Georgia Adopt-A-Stream's Habitat Assessment, Christopher H. Kodani, Robert Bourne, Cody Jones, Michael Kahle, Cecilia Nachtmann
Georgia Journal of Science
Habitat assessment is a skill that is important to stream ecologists of all levels, including volunteers of water quality monitoring programs such as Georgia Adopt-A-Stream (AAS). Some aspects of habitat assessment can be subjective because observers must use their best judgement in assessing some variables, therefore, it is worthwhile to examine the variation in volunteer stream monitor observations, the effect of training, and the reliability of habitat metrics calculated from the data collected. To gain some insight, we asked volunteers attending a workshop at AAS’s 2022 Confluence Conference to complete a Habitat Assessment Worksheet both before and after a short …
Racial Residential Segregation And Covid-19 Health Outcomes: Evidence From The State Of Georgia, Palak Patel, Simon Medcalfe, Catherine P. Slade
Racial Residential Segregation And Covid-19 Health Outcomes: Evidence From The State Of Georgia, Palak Patel, Simon Medcalfe, Catherine P. Slade
Journal of the Georgia Public Health Association
ABSTRACT
Background:
According to the Georgia Department of Public Health (GDPH), the state of Georgia reported 563,658 cumulative COVID-19 cases and 9,845 total deaths in 2020. Decades of research on racial disparities in health outcomes suggest we should not be surprised with the disproportionate number of cases, hospital visits, and deaths of non-white and Black Georgia residents. Racial disparities in health are often defined by a Social Determinants of Health (SDOH) model. One understudied SDOH is racial residential segregation. In this study we explore the relationship between racial residential segregation and COVID-19 health outcomes. Our paper addresses critical challenges for …

Advancements In The Programmable Hyperspectral Seawater Scanner Measurement Technology For Enhanced Detection Of Harmful Algal Blooms, John J. Langan, Jungyun Bae
Advancements In The Programmable Hyperspectral Seawater Scanner Measurement Technology For Enhanced Detection Of Harmful Algal Blooms, John J. Langan, Jungyun Bae
Michigan Tech Publications
The Programmable Hyperspectral Seawater Scanner (PHySS) represents a significant breakthrough in monitoring harmful algal blooms (HABs), specifically targeting the “Florida red tide” caused by Karenia brevis. By utilizing a Fourth-Derivative Spectral Similarity Index (SI), this study establishes a strong positive correlation between the SI and phytoplankton counts, underscoring the PHySS’s potential for early detection and effective management of HABs. Our findings suggest that the PHySS could act as a predictive tool, offering crucial lead time to mitigate the ecological and economic repercussions of blooms. However, this study also identifies certain limitations of the PHySS technology, such as its inability to …

Plant–hummingbird interactions are considered a classic example of coevolution, a process in which mutually dependent species influence each other's evolution. Plants depend on hummingbirds for pollination, whereas hummingbirds rely on nectar for food. As a step towards understanding coevolution, this review focuses on the macroevolutionary consequences of plant–hummingbird interactions, a relatively underexplored area in the current literature. We synthesize prior studies, illustrating the origins and dynamics of hummingbird pollination across different angiosperm clades previously pollinated by insects (mostly bees), bats, and passerine birds. In some cases, the crown age of hummingbirds pre-dates the plants they pollinate. In other cases, plant …
Historical Fire And Forest Structure In Western Dry Forests: Alternative Models, Controversies, And Management Plan Revision, Gordon Steinhoff
Historical Fire And Forest Structure In Western Dry Forests: Alternative Models, Controversies, And Management Plan Revision, Gordon Steinhoff
William & Mary Environmental Law and Policy Review
Management plan revision is currently underway for national forests in the Sierra Nevada Mountains of California, the Pacific Northwest, and other regions of the country under the U.S. Forest Service’s 2012 Planning Rule. With respect to dry ponderosa pine and mixed-conifer forests in the Sierra Nevada and Pacific Northwest, agency scientists and others claim that these forests were historically open and parklike, with primarily large, well-distributed trees, few smaller trees, and sparse underlying vegetation, leaf litter, and woody debris. Large, high-severity fire was rare. Fire exclusion since the early 1900s has led to the “densification” of these forests and unnatural …
Population Genetic Analysis Informs Dispersal Capacity In Representative Marine Trematodes From Family Microscaphidiidae And Family Paramphistomatidae, Randi Leigh Barton
Population Genetic Analysis Informs Dispersal Capacity In Representative Marine Trematodes From Family Microscaphidiidae And Family Paramphistomatidae, Randi Leigh Barton
Capstone Projects and Master's Theses
In marine and terrestrial systems, life history drives the distribution of organisms and informs the spatial scale of population connectivity. Nearly all bony reef fishes and invertebrates have a bipartite life cycle with a planktonic larval stage, which increases the organism’s dispersal capacity, and concludes with a relatively non-dispersive adult phase. While many studies have identified the relevant spatial scale for studying population structure in fishes and invertebrates, few have done the same for parasitic taxa, which have even more complex life histories with a higher diversity in the range of dispersal strategies they use. Parasite taxa differ in (1) …

A Dendrochronological Analysis Of Longleaf And Associated Pines From The Blackwater Ecological Preserve In Southeastern Virginia, Sarah Durham
Biological Sciences Theses & Dissertations
The field of dendrochronology utilizes annual tree ring growth data to create chronologies, which function as proxies to measure the effect of climate on radial growth. In the southeastern United States, dendrochronological studies involving the effect of climate on the growth of Pinus species exist, but significant gaps persist. For this study, I: 1) created chronologies of earlywood, latewood, and total ring-width growth for longleaf pine (Pinus palustris Mill.), loblolly pine (P. taeda L.), and pond pine (P. serotina Michx.) and 2) conducted a climate analysis on each species to determine how climatic factors affected radial …

The Anaerobic Rose Chamber (Arc): Novel Applications For Probing Clostridioides Difficile Dynamics, Tatiana Zvonareva
Chemistry & Biochemistry Theses & Dissertations
Clostridioides difficile infection (CDI) is an urgent public health threat with a high rate of recurrence and limited treatment options. Caused by the anaerobic intestinal pathogen C. difficile, this disease affects up to 500,000 Americans annually. Despite progress in our understanding of CDI pathophysiology, the lack of effective and accessible experimental platforms compatible with obligate anaerobe physiology hinders the advancement of treatment therapy. The application of in vivo models has been indispensable in understanding CDI pathophysiology, probing the complexity of the host response to the microbe, and establishing treatment protocols, and it continues to be essential in preclinical testing. …

Changes In Ground Beetle (Coleoptera: Carabidae) Species Assemblages After Removal Of Red Pine (Pinus Resinosa) Overstory On Dry Sand Prairie Sites In Michigan, Robert A. Haack, Toby Petrice, Robert L. Davidson, Robert E. Acciavatti
The Great Lakes Entomologist
Ground beetle (Coleoptera: Carabidae) species assemblages were studied at sites on the Huron-Manistee National Forests in Newaygo County, Michigan. The goal was to monitor changes in carabid diversity on areas where mature red pine (Pinus resinosa Sol. ex Aiton) was removed during the 1996-1997 winter and compare with carabid diversity at nearby natural dry sand prairie sites, natural oak-pine barrens, and uncut red pine stands. The red pine had been planted on dry sand prairie sites during 1940-1950. Sampling with pitfall traps occurred during May-August in both 1996 and 1997, but only July-August in 1999. Overall, 16,259 carabid specimens …

School of Integrative Biological & Chemical Sciences Faculty Publications
Background
Bioacoustic monitoring is an effective and minimally invasive method to study wildlife ecology. However, even the state-of-the-art techniques for analyzing birdsongs decrease in accuracy in the presence of extraneous signals such as anthropogenic noise and vocalizations of non-target species. Deep supervised source separation (DSSS) algorithms have been shown to effectively separate mixtures of animal vocalizations. However, in practice, recording sites also have site-specific variations and unique background audio that need to be removed, warranting the need for site-specific data.
Methods
Here, we test the potential of training DSSS models on site-specific bird vocalizations and background audio. We used a …
Melanism In Polymorphic Terrestrial Snakes: A Meta-Analysis And Systematic Review, Ryan A. Martin
Melanism In Polymorphic Terrestrial Snakes: A Meta-Analysis And Systematic Review, Ryan A. Martin
Faculty Scholarship
Background and Aim: Colour polymorphic populations constitute excellent model systems for testing ecological and evolutionary hypotheses, as alternate colourations are associated with differences in various biological, behavioural and life-history traits. Melanism is the most common and most obvious form of polymorphism. In reptiles in general (and snakes in particular), thermal melanism has been a popular hypothesis used to explain the appearance of black individuals. It suggests that a trade-off exists between superior thermoregulation and reduced protection through the loss of crypsis. Surprisingly, despite the growing body of literature available, to date, there are only two qualitative reviews on the evolutionary …

Contaminant Exposure And Liver And Kidney Lesions In North American River Otters In The Indian River Lagoon, Florida, Ami Krasner, Megan Stolen, David Rotstein, Spencer Fire
Ocean Engineering and Marine Sciences Student Publications
The harmful algal bloom (HAB) liver toxin microcystin (MC) and trace element biomagnification were previously detected in organisms in the Indian River Lagoon (IRL), Florida. Since there are no routine screening programs for these contaminants, liver tissue from North American river otters (Lontra canadensis), an important sentinel species in the IRL, was screened for MC via enzyme-linked immunoassay (ELISA), followed by confirmatory analyses via liquid-chromatography/mass spectrometry methods (LC-MS/MS). Liver and kidney samples were evaluated for trace element (As, Cd, Co, Cu, Fe, Hg, Mn, Mo, Pb, Se, Tl, and Zn) bioaccumulation via inductively coupled plasma mass spectrometry (ICP-MS). Histopathologic evaluation …
