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 …

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 …

The Ground Baiting Component Of The Gough Island House Mouse Eradication Attempt In 2021, Araceli Samaniego, Andrew Callender, Pete Mcclelland

Human–Wildlife Interactions

House mice (Mus musculus; mice) are among the most widespread invasive species. On Gough Island (6,500 ha), mice preying on at least 19 bird species triggered a mouse eradication attempt. Gough Island is a volcanic island in the South Atlantic Ocean and part of Tristan da Cunha, a UK Overseas Territory. From June to August 2021, an expert team applied an anticoagulant rodenticide (active ingredient brodifacoum at a concentration 20 ppm) island-wide, predominantly via aerial broadcast using helicopters, as the island is mainly uninhabited. However, hand-baiting was also required because of the presence of a staffed meteorological station. …

An Assessment Of The Potential Hazards Of Anticoagulant Rodenticides To Plethodontid Salamanders, Gary W. Witmer, Steven F. Volker

Human–Wildlife Interactions

We assessed the hazards of the anticoagulants diphacinone and brodifacoum to salamanders of the family Plethodontidae or lungless salamanders. We completed this research in anticipation of an attempt to eradicate the invasive house mouse (Mus musculus) from the Farallon Islands National Wildlife Refuge, California, USA, where the endemic subspecies Farallon arboreal salamander (Aneides lugubris farallonensis) occurs. We exposed live-captured salamanders of 3 species (Aneides lugubris, Ensatina eschscholzii xanthoptica, and Batrachoseps attenuatus) to anticoagulant rodenticides by both oral and dermal exposure routes in laboratories at the U.S. Department of Agriculture, Animal and Plant Health …

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, …

A Look To The Future: New And Innovative Invasive Wildlife Management And Eradication Technologies, Aaron B. Shiels, Katherine E. Horak

Human–Wildlife Interactions

Certain wildlife tools and discoveries have been true “game changers” for invasive species management and eradications on islands. This article provides an overview of 3 cutting-edge technologies that are being eagerly pursued, but are not yet operational, for invasive wildlife management to build efficiency, reduce environmental impacts, and/or improve animal welfare practices.

Effectiveness Of Citizen Engagement In A State Agency Egg-Oiling Program To Reduce Urban Canada Goose Populations And Conflicts, Charles H. Cope, Tom F. Bidrowski, Jon P. Beckmann

Human–Wildlife Interactions

In many cases, urban environments create high-quality habitat for wildlife that may allow species to form commensal relationships with humans. Positive impacts of urban environments (e.g., high-quality nesting habitat) may enhance survival and/or increased fecundity. One species that has shown the ability to form commensal relationships with humans in urban environments is Canada geese (Branta canadensis). Canada goose populations have continued to rebound in Kansas, USA, and across the Great Plains, such that the estimated resident population in Wichita, Kansas, grew from 0 to >5,000 resident geese and the over-winter population increased from 1,600 in 1997 to >18,000 …

Asiatic Black Bear Microsite Selection In A Human-Dominated Landscape In The Central Alps, Japan: Implications For Mitigating Human–Bear Conflicts, Tomoki Mori, Shigeyuki Izumiyama

Human–Wildlife Interactions

With the rapid expansion of human development and associated changes in landscape use, opportunities for human land sharing with large mammalian carnivores, such as those belong to the family Ursidae is increasing, especially in human-dominated landscapes. Consequently, this increased coexistence has also led to an increase in human–bear (Ursus spp.) interactions. It is important to understand the spatial and temporal reactions (e.g., interactions between cover, time, and humans) of bears to mitigate human–bear conflicts and facilitate coexistence. However, managers often need better information regarding bear microsite habitat selection in areas with higher levels of human–bear encounter risks. We explored …

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 ( …

An Unmanned Aircraft System For Marking Live Power Lines To Prevent Bird Collisions, Mattheuns D. Pretorius, Lourens Leeuwner, Kaajial Durgapersad, Constant Hoogstad, Peter Beckedahl, Michael D. Michael, Kishaylin Chetty

Human–Wildlife Interactions

Collisions with overhead power lines represent a significant cause of mortality for a number of large bird species worldwide. Certain threatened species are severely impacted by power line collisions, particularly those for which there are no other known significant threats. In South Africa, bird collisions with overhead power line cables, including collisions with phase conductors and shield wires, contribute significantly to annual threatened bird species mortalities associated with Eskom power lines. The most practical mitigation measure is to attach bird anti-collision devices as markers on the cables. Current marking methods involve installations by hand, where linemen are hoisted up to …

Raccoon Selection For Anthropogenic Resources Provides Challenges For Wildlife Management In Yosemite Valley, Erika L. Anderson, Sean M. Matthews, David S. Green, E. Binta Wold, Katie Patrick, Rachel Mazur

Human–Wildlife Interactions

Managing human–wildlife incidents dominates the attention and resources of many wildlife management programs. National parks in the United States have a long history with human–wildlife interactions and conflicts. Improvements in communication with visitors, food-storage infrastructure, regulation enforcement, and the management of habituated and food-conditioned animals have decreased human–wildlife conflicts. Yosemite National Park, California, USA, is well known for its history of human–bear (Ursus spp.) conflicts. However, in the Yosemite Valley portion of Yosemite National Park, conflicts with raccoons (Procyon lotor) now outnumber those with black bears (U. americanus). Like bears, raccoons pose a risk of …

Human–Alligator Incidents In The United States: Risky Human Behaviors Cause Most “Attacks”, Mark S. Teshera, Azar Kordbacheh, Frank J. Mazzotti

Human–Wildlife Interactions

Interactions between humans and American alligators (Alligator mississippiensis), often resulting in negative outcomes for both participants, have occurred for centuries in the United States. As both populations increased over time, contact and conflict with one another became inevitable. Although human–alligator conflicts have been well documented, there has been no detailed classification of risk factors associated with human activities immediately preceding, and in most cases precipitating, an encounter. Herein, we provide a ranking system to categorize different human activities, based on risk levels, immediately preceding an encounter with an alligator. To complete our review in 2021, we initially gleaned …

The Impact Of Feral Honey Bees On Endangered Seabirds In The Hawaiian Islands, André Francis Raine, Scott Driskill, Stephen Rossiter, Jennifer Rothe, Kyle Pias, Rachel Sprague, Alex Dutcher

Human–Wildlife Interactions

The ʻaʻo (Puffinus newellii; Newell’s shearwater) and ʻuaʻu (Pterodroma sandwichensis; Hawaiian petrel) are both endangered seabirds endemic to the Hawaiian Archipelago. For the last decade, multiple colonies on the islands of Kauaʻi and Lānaʻi have been the focus of intensive management (particularly predator control) and monitoring programs. Management has been effective at reducing the number of introduced mammalian predators recorded within colonies with a resultant increase in reproductive success rates for both seabird species. However, in recent years a new threat has emerged—feral honey bees (Apis mellifera; bees)—which were deliberately introduced to the Hawaiian …

Lawyering Somewhere Between Computation And The Will To Act: A Digital Age Reflection, Jeffrey M. Lipshaw

Suffolk University Law School Faculty Works

This is a reflection on machine and human contributions to lawyering in the digital age. Increasingly capable machines can already unleash massive processing power on vast stores of discovery and research data to assess relevancies and, at times, to predict legal outcomes. At the same time, there is wide acceptance, at least among legal academics, of the conclusions from behavioral psychology that slow, deliberative “System 2” thinking (perhaps replicated computationally) needs to control the heuristics and biases to which fast, intuitive “System 1” thinking is prone. Together, those trends portend computational deliberation – artificial intelligence or machine learning – substituting …

Pre-Session Pairing Impacts On Compliance, Britton Dallas

Research Papers

Autism Spectrum Disorder (ASD) is a developmental disability with persistent deficits in communication, social interactions, and the occurrence of repetitive or restricted patterns of behavior. Individuals with ASD also commonly engage in challenging behaviors. Early intensive behavioral intervention (EIBI), based on applied behavioral analysis (ABA), is a recommended treatment for children with ASD to address these deficits and excesses. Challenging behaviors in those with ASD have been derived by the presentation of instructions. To circumvent challenging behaviors during instruction periods, research has recommended that pre-session pairing should occur prior to initiating demands. In the present study, three children diagnosed with …

Still, We Thrive: Understanding How Gay, Bisexual, Transgender, And Other Men Who Have Sex With Men (Gbtmsm) Experience Structural Barriers & Facilitators To Wellness, Lucas Gergyek

Theses and Dissertations (Comprehensive)

Historically and concurrently, structural violence has been a significant force influencing the sexual health and broader health of gay, bisexual, transgender and other men who have sex with men (GBTMSM). Yet to date, the majority of projects exploring the health inequities facing GBTMSM have focused on intrapsychic and behavioural factors as most related to poor health outcomes. As well, these studies are sometimes deficits focused, and fail to evaluate how GBTMSM continue to thrive, and maintain positive health. As a result, the ways in which systems and policies underlie and perpetuate health inequities facing GBTMSM have been somewhat obscured. Connectedly, …

I Am Queer And Asian: The Crossroad Of Race And Lgbtqia+ Identity Among Queer Asian Canadian Youth And The Impacts Of The Covid-19 Pandemic, Kenny Chee

Theses and Dissertations (Comprehensive)

LGBTQIA+ Asian youth face unique challenges due to their intersecting identities. Utilizing Asian Critical Race Theory and the Integration Model of Stress and Trauma in LGBTQIA+ Asians, LGBTQIA+ Asian youth are likely to experience detrimental mental health outcomes due to the stigmatization within their Asian culture and racial discrimination from the LGBTQIA+ communities. Moreover, the COVID-19 pandemic exacerbated existing challenges because of the closure of community spaces and increased hate crimes against Asians. Nonetheless, research on the intersectional experiences of LGBTQIA+ Asians in Canada, especially in the context of the COVID-19 pandemic is sparse. Thus, to address this gap, I …

Examining Foot And Lower Leg Muscular Activation During Slip Recovery, Keara Sutherland

Theses and Dissertations (Comprehensive)

Slips during gait are the leading cause of falls and subsequent serious injury in young and older adults. Reactive balance responses generated by the lower limb muscles can restore balance and minimize the chance of experiencing a fall. The purpose of this study was to examine the role of the deep muscles in the lower leg and muscles within the foot during recovery from an unexpected slip perturbation. We hypothesized that lower leg musculature and intrinsic foot muscles would exhibit an earlier onset, longer duration, and increased magnitude during slips compared to level walking and that muscle activity would have …

Employees’ Reactions To Their Supervisors’ (Lack Of) Discretionary Adjustments In Performance Evaluations, Joanna Andrejkow

Theses and Dissertations (Comprehensive)

The purpose of my dissertation is to investigate how employees react to their supervisors’ decisions not to use ex-post discretionary adjustments to mitigate the effects that negative unexpected events have on their bonuses. To address this objective, I pose the following research question: Will the level of interdependence inherent within the compensation of multiple employees (i.e., compensation interdependence) and the likelihood the event will reoccur (i.e., future event likelihood) affect employees’ reactions (future effort and workplace deviance) when they don’t receive ex-post discretionary adjustments to mitigate the effects of negative events?

I address my research question using an experiment where …

Disrupting And Expanding The Discourse: Palliative Care Clinicians' Experiences With Patients' Non-Physical Suffering, Maxxine Rattner

Theses and Dissertations (Comprehensive)

While one of the primary aims of palliative care is to prevent and relieve suffering, both physical and non-physical, research to date has been very limited re: clinicians’ experiences with patients’ non-physical suffering (e.g., suffering that may be psychological, emotional, social, spiritual and/or existential in nature); both how clinicians work with/respond to this kind of suffering in their day-to-day work, and the effect of this aspect of their work on clinicians themselves. No research to date has considered the impact of palliative care’s dominant non-physical suffering discourse — which presents the relief of non-physical suffering as falling along a binary …

Vapourized Cannabis Extract Administration Impairs Memory And Alters Neural Activity In Laboratory Rats, Megan Chladny

Theses and Dissertations (Comprehensive)

Although people have smoked cannabis for millennia, administration of cannabis by heating the dried plant material or distilled extracts to a temperature just below the combustion point (i.e., vapourization or "vaping") has rapidly increased over the past few years (Javadi-Payder, Cole, and Taffe, 2018; Manwell, Charchoglyan, Brewer, Matthews, Heipel, and Mallet, 2014). Conversely, most of the cannabinoid research using rodent models has used parenteral routes of administration to examine the effects of purified cannabis extracts such as ∆⁹-tetrahydrocannabinol (THC), making it difficult to directly compare laboratory research to human drug use. Building on previous studies showing that THC …

Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski

Theses and Dissertations (Comprehensive)

The vast majority of the research into the performance of stormwater management ponds (SWMPs) has been performed in warm regions or during the warmer seasons in temperate regions. It is presumed that SWMPs are inactive in the winter as any potential stormwater is trapped in snow and ice. The main goal of this thesis was to test this presumption and to study the dynamics and performance of three SWMPs during the winter. Remote water level loggers were installed into the three SWMPs and daily grab samples from the influents and effluents were taken and analyzed for total phosphorus (TP), chloride, …

Assessment Of Stream Metabolism And Associated Environmental Drivers In The Greiner Lake Watershed, Nunavut, Canada, Nicole Gotkowski

Theses and Dissertations (Comprehensive)

Stream metabolism is an ecological process that can be monitored to assess carbon cycling and productivity within a stream ecosystem. GPP (gross primary productivity) is measured as oxygen produced by autotrophs and ER (ecosystem respiration), which is measured by oxygen depleted by all living organisms. Complications arise when estimating GPP and ER in the Arctic because most methods require a period of darkness when GPP ceases, however, summer regimes of photosynthetically active radiation (PAR) do not reach zero. Furthermore, natural diffusion of oxygen from the atmosphere (k) must be accounted for but this requires extensive field work, thus posing problems …

Assessing The Biocatalytic Promiscuity Of Pep- Transformations For Geminal-Difluorination, Eloy Jose Torres Garcia

Theses and Dissertations (Comprehensive)

Fluorine is the most electronegative chemical element and can drastically change molecular properties, such as drug pharmacokinetics and agrochemical half-life. Although a great deal of progress is occurring in synthetic methods to access various organofluorines, these methods struggle with harsh conditions and limited substrate scope. Biocatalytic approaches offer the potential to access organofluorines that are difficult or impossible with the current methodology. Phosphoenolpyruvate (PEP) is a central metabolite and biosynthetic precursor for diverse molecules. Phosphoenol pyruvate mutase (Ppm) catalyses the interconversion of Phosphonopyruvate (PnPy) to Phosphoenolpyruvate (PEP). This research successfully expressed and …

Contrasting Seasonal Cycling Of Arsenic In A Series Of Subarctic Shield Lakes With Different Morphometric Properties, Jeremy Harbinson

Theses and Dissertations (Comprehensive)

The subarctic shield near Yellowknife, Northwest Territories (NWT), is populated with thousands of small lakes (<1.5 km²) and several large lakes. Historic mining activities in the region have left a legacy of environmental impacts and widespread arsenic (As) contamination in both aquatic and terrestrial environments. In particular, several small subarctic lakes near Yellowknife have been previously documented to be contaminated with high levels of As. Subarctic lakes are characterized by seasonal ice-cover that can persist for more than half of the year, yet little is known about the under-ice spatial and seasonal dynamics of As cycling. The objective of …

Distinctiveness And Similarity: How The Sub-Trait Facets Of The Big Five Self-Organize To Create Personality Types, Jonathan Thiessen

Theses and Dissertations (Comprehensive)

The belief that people can be placed within a personality typology has persisted for millennia. At least as far back as Hippocrates (ca. 460 BCE–370 BCE) people were believed to be of a kind based on the four humors—blood, yellow bile, black bile, and phlegm. Since then, there have been many conceptions of personality typologies. The Myers-Briggs Type Indicator and the Enneagram of Personality are likely the most well-known personality typologies among the general public. Despite their wide public usage, neither typology boasts strong empirical support. However, psychology continues to investigate personality for evidence of a typology of personality. In …
