Human Impacts On Mammal Diversity From The Pleistocene To The Present, Carson P. Hedberg

Biology ETDs

Humans have fundamentally altered the planet’s biodiversity. It is critical to characterize these changes, but also to understand how they impact the structure and function of modern ecosystems. This dissertation investigates how anthropogenically mediated species losses and/or introductions influence ecological function and community structure in mammals across multiple temporal and spatial scales. We found that selective loss of large-bodied mammals over the Late Quaternary has led to severe losses in functional diversity in modern ecosystems, suggesting megafaunal mammals contribute distinct ecological functions. These changes to mammal diversity and distribution over millennia have altered both global patterns in functional diversity and …

No Change In Functional Ecology Or Body Size In Response To A Global Climate Event In The Late Maastrichtian Owl Creek Formation, William T. Rizza

Master's Theses

During the last 300 ka of the Maastrichtian, global temperatures increased and decreased by ~2℃, likely caused by a pulse of Deccan volcanism. The Owl Creek Type Section in Mississippi records some portion of the last 400 ka of the Late Maastrichtian. It is expected that marine invertebrates will demonstrate a taxonomic, ecological, or morphological response to rapid temperature change. I anticipate a decrease in taxonomic diversity and shell volume and an increased abundance of low activity-level species, similar to the ecological impacts observed in response to Large Igneous Province eruptions in the geologic record. Clumped isotope paleotemperature reconstruction recovers …

Cities and the Environment (CATE)

The Seaport Platform of Environmental Surveillance (PPSE, or Plateforme Portuaire de Surveillance Environnementale in French) was officially inaugurated in Cotonou Seaport (CS), Benin, by the end of 2021. To our knowledge, this platform is the first laboratory dedicated to the monitoring and management of invasive species to be built inside the walls of an African seaport. Its creation has benefitted from a combination of favorable factors, and its existence has resulted from a long-term, multi-stakeholder and still ongoing process that we here describe and analyze. We believe that the PPSE is an innovative science-guided operational initiative that may be useful …

Pigs And The City, Sayd Randle

Asian Management Insights

Urban greening requires a re-look at sharing space with animals and nature.

1. There are several challenges when balancing urban development with ecological sustainability, as seen in Singapore’s struggles with human-wildlife interactions like wild boars entering populated areas.

2. Opinions on managing wildlife diverge between calls for stricter population control and concerns over habitat loss. This shows the need for balanced approaches that cater to both humans and ecology alike.

3. Cities like Houston, Barcelona, and Hong Kong offer different models for human-wildlife management, showing that local contexts shape approaches to achieving peaceful coexistence with urban wildlife.

This study introduces a pioneering methodology that integrates Dynamic Bayesian Networks of ecosystem resilience with climate projections, aiming to enhance our understanding of seagrass responses to extreme climate events. We developed cutting-edge metrics for measuring shoot density and biomass in terms of population and site extinction, presented as annual ratios relative to their respective baselines. These metrics include associated uncertainties and projected recovery times. This innovative approach was applied in a case study focusing on …

A Neutrosophic Model For Measuring Evolution, Involution, And Indeterminacy In Species: Integrating Common And Uncommon Traits In Environmental Adaptation, Antonios Paraskevas, Michael Madas

Neutrosophic Systems with Applications

In 2017, Professor F. Smarandache introduced the Neutrosophic Theory of Evolution, Involution, and Indeterminacy (or Neutrality) (NToEIaI). He concluded that every theory of evolution is characterized by a certain degree of truth, indeterminacy, and untruth, as in neutrosophic logic. In this perspective, he raised several open questions on evolution, neutrality, and involution that required further research effort. Very recently, in 2024, Smarandache conducted research, from a soft sciences/philosophical viewpoint, on identifying and studying common parts in uncommon things and uncommon parts in common things emphasizing the complexity and interconnectedness of concepts within the context of neutrosophy. In this article, we …

Neighborhood Effects On Acute Pediatric Asthma: Race, Greenspace, And Pm2.5, Elizabeth Wesley, Nathaniel A. Brunsell, David R. Rahn, Jarron M. Saint Onge, Natalie J. Kane, Kevin F. Kennedy

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

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

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 …
