Response Of Running Buffalo Clover (Trifolium Stoloniferum Muhl Ex. A. Eaton) To Herbaceous Competition And Transplanting In Monongahela National Forest, Ruben E. Sabella

Graduate Theses, Dissertations, and Problem Reports (ETD)

Running buffalo clover (RBC) is a rare perennial plant that grows throughout the American Midwest and the Appalachian Mountains. It requires disturbed forests to establish and proliferate. It has been suggested that, in the past, these conditions were created by buffalo; now logging operations maintain RBC populations. However, forest managers have been looking for ways to create suitable habitat for RBC that do not involve harvesting practices. This could help create new populations in areas that cannot be logged. Once established, competing vegetation might influence RBC abundance and flowering. This study seeks to quantify this influence by measuring the vegetation …

Multimodal Neuron Classification Based On Morphology And Electrophysiology, Aqib Ahmad

Graduate Theses, Dissertations, and Problem Reports (ETD)

Categorizing neurons into different types to understand neural circuits and ultimately brain function is a major challenge in neuroscience. While electrical properties are critical in defining a neuron, its morphology is equally important. Advancements in single-cell analysis methods have allowed neuroscientists to simultaneously capture multiple data modalities from a neuron. We propose a method to classify neurons using both morphological structure and electrophysiology. Current approaches are based on a limited analysis of morphological features. We propose to use a new graph neural network to learn representations that more comprehensively account for the complexity of the shape of neuronal structures. In …

Optimizing Sample Collection And Data Interpretation For Effective Wastewater-Based Epidemiology In Combined Sewer Systems, Christopher Allen Anderson

Graduate Theses, Dissertations, and Problem Reports (ETD)

COVID-19 has spurred growth in the science surrounding wastewater-based epidemiology (WBE) pertaining to the detection of severe acute respiratory virus 2 (SARS-CoV-2) in waste streams as an early warning signal for public health. However, the highly variable wastewater environment has made it difficult to standardize an approach for sampling and analysis, especially in locations using combined sewer infrastructure. This study addresses knowledge gaps of WBE via three specific aims: (1) to compare diurnal fluctuations of SARS-CoV-2 and the human fecal indicator, pepper mild mottle virus (PMMoV) in wastewater treatment plant (WWTP) influent samples collected during dry versus wet weather conditions; …

Tradeoffs May Counteract Effects Of Telecommunication Towers On Osprey Nesting, Gage R. Barnes, Kate G. Slankard, John B. Hewlett, Andrea K. Darracq

Human–Wildlife Interactions

The number of telecommunication towers (TCTs) throughout the United States has and continues to increase exponentially. Increased TCT placement has been implicated in local population increases in platform nesting birds such as ospreys (Pandion haliaetus). However, osprey use of artificial structures can cause conflicts with humans because of economic costs and risks to human safety. Managers require better information regarding the effect of artificial nesting surfaces, such as TCTS, on osprey reproduction to make informed decisions regarding species conservation and to mitigate potential conflicts. The objective of our study was to evaluate the influence of TCTs on osprey …

Ecological Associations Of Nonnative Ungulates On The Hawaiian Island Of Lāna‘I, Steven C. Hess, Lucas Berio Fortini, Christina R. Leopold, Jacob Muise, Jonathan C. Sprague

Human–Wildlife Interactions

Abstract: Sustained-yield hunting of introduced ungulates in the Hawaiian Islands often conflicts with the conservation of native species, but there is little reliable data to guide effective management. European mouflon sheep (Ovis musimon; mouflon) and axis deer (Axis axis; deer) were introduced on the island of Lāna‘i to provide additional hunting opportunities. Managers will require better information regarding the ecological associations of introduced ungulate species, relative to the habitats occupied, to resolve longstanding conflicts between native species conservation and sustained-yield hunting on islands. To address this information need, we modeled sheep and deer ecological associations, habitat-use, …

Potential For Policy Conflict Among Alligator Hunters In Texas, Usa, Christopher Serenari, Elizabeth N. Pratt, Abigail Meeks, Elena C. Rubino, Kristy L. Daniel

Human–Wildlife Interactions

Policy termination is a tool to ensure that antiquated or underperforming policies are updated or replaced. Understanding how terminating a policy might be received by core wildlife constituencies, such as hunters, is a critical insight to provide agencies and managers with the tools to make wildlife policy changes a more seamless process. However, this critical but negative policy approach is often overlooked in favor of investigating positive policy preferences (i.e., preferences for new policy). To help fill this gap, we applied the potential for conflict index (PCI₂) to data from a survey of 318 spring American alligator ( …

Human–Black Bear Interactions And Public Attitudinal Changes In An Urban Ordinance Zone, Mark A. Barrett, Sarah E. Barrett, David J. Telesco, Michael A. Orlando

Human–Wildlife Interactions

Human–bear (Ursus spp.) interactions (HBI) commonly occur in residential areas throughout North America. Negative HBI can be alleviated by using bear-resistant garbage cans (BRC) and by securing other bear attractants (e.g., bird feeders). Since the early 2000s, human and Florida black bear (U. americanus floridanus) densities have increased substantially throughout Florida, USA, concurrently producing an increase in HBI. In central Florida, an area with high densities of humans and black bears, we surveyed 2 neighborhoods that occurred in an urban ordinance zone established in 2016 that required residents to secure anthropogenic food sources. Residents were supplied with …

The Lord Howe Island Rodent Eradication: Social And Technical Lessons For Inhabited Islands, Grant A. Harper, Simon Pahor, Kelly Harrington, Darcelle Matassoni, Darryl Birch

Human–Wildlife Interactions

The 2019 rodent eradication on 1,455-ha Lord Howe Island, Australia, was the second and largest attempted on a permanently inhabited island. With 445 residents, it presented numerous novel challenges, resulting in an operation best summarized in 4 words: compromise, commensal, complexity, and cost. A ground-based operation was conducted across the inhabited portion of the island, some 300 ha known as the “settlement,” with aerial bait applied on forested hill country and cliffs (1,200 ha). Initial community resistance and the presence of mice (Mus musculus) meant that almost 19,000 external bait stations were established within the settlement, on a …

Establishing A Volunteer Group To Assist In The Eradication Of Invasive Brown Treesnakes From Islan Dåno' (Cocos Island), Guam, Martin Kastner, Olympia Terral

Human–Wildlife Interactions

Islan Dåno’ (Cocos Island) is an islet of high conservation value located 2.5 km off Guam, USA, in the Western Pacific. It has long been considered free from invasive brown treesnakes (Boiga irregularis; BTS). A recently confirmed breeding population of BTS puts its wildlife populations, including U.S. Endangered Species Act-listed lizard and bird species, at risk. In response, we established Guam’s first volunteer group dedicated to BTS eradication, which we named Friends of Islan Dåno’. We provided training to local volunteer snake searchers and organized regular night searches for BTS on Islan Dåno’. We completed 25 searches between …

Neuromorphic Computing Applications In Robotics, Noah Zins

Dissertations, Master's Theses and Master's Reports

Deep learning achieves remarkable success through training using massively labeled datasets. However, the high demands on the datasets impede the feasibility of deep learning in edge computing scenarios and suffer from the data scarcity issue. Rather than relying on labeled data, animals learn by interacting with their surroundings and memorizing the relationships between events and objects. This learning paradigm is referred to as associative learning. The successful implementation of associative learning imitates self-learning schemes analogous to animals which resolve the challenges of deep learning. Current state-of-the-art implementations of associative memory are limited to simulations with small-scale and offline paradigms. Thus, …
