Landscape Characteristics Predict Locations For Potential Human–Wildlife Interactions With Timber Rattlesnakes In Minnesota, Usa, Ben M. Borash, Benjamin P. Pauli

Human–Wildlife Interactions

While management measures cannot eliminate human–wildlife conflicts, they have the potential to minimize the damage done to both parties, especially if areas where the nature of the potential interaction can be predicted before an encounter occurs. The timber rattlesnake (Crotalus horridus) represents a wildlife species associated with public misconceptions that may foster unwarranted fears and retribution. This species is native to the eastern and southern regions of the United States, including a small population remnant in the southeastern region of Minnesota. To gain a better understanding of the environmental predictors relevant to human–snake encounters in Minnesota (that require …

Human–Carnivore Conflicts In A Recently Established Pakistani National Park, Rukhsana Khatoon, Maqsood Anwar, Charles H. Nilon, Matthew E. Gompper

Human–Wildlife Interactions

Human–carnivore conflicts (HCCs) are increasing globally. These conflicts may encompass competition for food resources, crop and livestock depredations, and attacks on humans. Concerns over conflicts may result in retaliatory killings of carnivores and negative views of wildlife or landscape conservation. Yet, despite the economic and conservation implications of HCCs, data regarding the magnitude and severity of the conflicts may be lacking because many incidents are unreported. To better inform this issue, we compared HCC data for 2016 to 2018 obtained from official records of the Punjab Wildlife and Parks Department for a newly established national park in the Punjab Region …

U.S. Public Opinion Of Reproductive Control Options For Free-Roaming Horses On Western Public Lands, S. Nicole Frey, Jeffrey L. Beck, John Derek Scasta, Loretta Singletary

Human–Wildlife Interactions

Free-roaming horses (Equus ferus caballus; horses) inhabit public rangelands located primarily in 10 western U.S. states. Recent horse population increases are impacting rangeland ecosystems, native wildlife species and their habitats, and exacerbating conflicts with domestic livestock grazing. While contraceptives and physical sterilization are promising options to manage horse herd levels, public opinion concerning the use of fertility control is not well understood. To better inform policymakers, we completed a rigorous study of a random sample of public land stakeholders across the United States (n = 3,500) in 2020 using a Likert scale online survey to assess their …

Healthy Western Lands: A Proposal For Healthy Rangelands, Wildlife, And Free-Roaming Horses And Burros, James S. Sedinger, Rebekah Stetson

Human–Wildlife Interactions

The Coalition for Healthy Nevada Lands, Wildlife and Free-roaming Horses (CHNL) is dedicated to proper management of free-roaming horses (Equus caballus) and burros (E. asinus) so rangelands are healthy, which benefits wildlife and the horses and burros themselves. The CHNL proposes the rapid reduction of horses and burros on designated public lands to achieve appropriate management levels (AML). After these reductions, the use of fertility control, supplemented with some gathers and adoption of gathered horses, should allow the Bureau of Land Management to economically maintain horse and burro populations at AML. The CHNL believes this approach …

New Research And Wild Horse And Burro Management, David Jenkins

Human–Wildlife Interactions

In the United States, the Wild Free-Roaming Horses and Burros Act (WFRHBA) gave the Bureau of Land Management (BLM) and the U.S. Forest Service the statutory obligation to manage and protect free-roaming equids (i.e., wild horses [Equus ferus] and burros [E. asinus]) on designated management areas on public land. The WFRHBA was intended to ensure that wild horses and burros on the public lands exist in self-sustaining herds in perpetuity, alongside other congressionally mandated, multiple uses of public lands. The BLM recently published a strategic research plan for their wild horse and burro program. The research …

Enhancing Stakeholder Engagement To Achieve The Sustainable Management Of Free-Roaming Equids, Celeste Carlisle, Dan Adams

Human–Wildlife Interactions

Wild horse (Equus caballus) and burro (E. asinus; WHB) stakeholders in the American West are divergent in their views of free-roaming equids on public lands. Management authority for free-roaming equids on designated public lands was given to the Bureau of Land Management (BLM) and the U.S. Forest Service (USFS) in 1971 by U.S. Congress with the passing of the Wild and Free-Roaming Horses and Burros Act (WFRHBA). In 1976, the Federal Land Policy and Management Act (FLPMA) mandated the BLM to manage public lands for multiple-uses, which included livestock grazing, energy development, recreation, and timber harvest. …

Partnerships Create Success For The Devil’S Garden Wild Horses, Laura K. Snell

Human–Wildlife Interactions

Many wild horse (Equus ferus caballus) populations that inhabit designated federal land in the United States currently exceed management objectives. Overabundant wild horse populations can adversely impact the ecosystem, native wildlife, and other land uses. Unfortunately, there is not a universal solution, as each impacted area may differ ecologically, economically, socially, and politically. Wild horse management is not just a 1-time project but a long-term program where buy-in is needed from the federal and state agencies, local governments, and private partners. Local county governments and private partners can have important insights and significant influence on the development and …

Dehydration And Mortality Of Feral Horses And Burros: A Systematic Review Of Reported Deaths, John Derek Scasta, Eric Thacker, Jacob D. Hennig, Karl Hoopes

Human–Wildlife Interactions

Water is a requirement for all organisms, including equids. Dehydration-caused mortality of feral horses (Equus ferus caballus) is often cited as a cause of concern and as justification for management of feral horses, yet a paucity of information exists on the matter. We conducted a systematic review from September 1, 2020 through January 15, 2021 of available news reports of feral horse and burro (E. asinus) dehydration mortalities and public interventions to save horses using a public search engine with a priori defined search term combinations and additional snowball sampling. We found 15 uniquely reported mortality …

Texas Hunters’ Perceptions Regarding The Acceptability Of Toxicants To Control Wild Pig Populations, Keith M. Carlisle, Sophie Mckee, Hailey E. Ellis, Lauren M. Jaebker, John M. Tomeček, Alan D. Bright, Rachael L. Connally, Maureen G. Frank, Stephanie A. Shwiff

Human–Wildlife Interactions

Wild pigs (Sus scrofa) are an invasive species in the United States. They damage agriculture, degrade water quality and ecological communities, and host a number of viruses, parasites, and bacteria transmissible to humans and animals. In states such as Texas, USA, where wild pigs cause extensive damage to agriculture and property, officials have considered allowing for the use of toxicants to control wild pig populations. To provide decision-makers with information regarding stakeholders’ perceptions of the use of toxicants to control wild pigs, we surveyed Texas hunters in 2019 to assess the level of acceptance of a hypothetical wild …

A Call For Ethical And Responsible Treatment Of Invasive Species By Recreational Anglers, Kevin A. Adeli

Human–Wildlife Interactions

Invasive species pose a prominent threat to global biodiversity, with aquatic ecosystems being particularly susceptible. In an effort to limit the spread of aquatic invasive species, numerous public awareness programs have been launched, and several regions have enacted “must-kill” angling regulations, which prohibit the live release of invasive fish species when captured. Many education programs, however, demonize invasive species and lack any instruction for humane euthanasia. This unbalanced approach has translated into widespread mistreatment of invasive species among recreational anglers. This piece addresses these concerns by discussing their significance and providing recommendations for how education programs can adopt a more …

Exclusion Cycles: Reinforcing Disparities In Medicine, Ana Bracic, Shawneequa L. Callier, Nicholson Price

Articles

Minoritized populations face exclusion across contexts from politics to welfare to medicine. In medicine, exclusion manifests in substantial disparities in practice and in outcome. While these disparities arise from many sources, the interaction between institutions, dominant-group behaviors, and minoritized responses shape the overall pattern and are key to improving it. We apply the theory of exclusion cycles to medical practice, the collection of medical big data, and the development of artificial intelligence in medicine. These cycles are both self-reinforcing and other-reinforcing, leading to dismayingly persistent exclusion. The interactions between such cycles offer lessons and prescriptions for effective policy.

Beyond Homogenous Decision-Making Models: Role Of Brain Areas Interaction And Heterogeneity, Mohsen Rakhshan

Dartmouth College Ph.D Dissertations

Most existing mechanistic models of decision making consider microcircuits within a homogenous brain area and fail to consider the distributed nature of this cognitive process. More specifically, these models do not take into account: a) how different types of information might influence choice in different stages of the process; and b) how interactions and the heterogeneity between circuits across different brain areas might be essential for the process. In this dissertation, I present a combination of experimental and modeling approaches to study distributed nature of the decision-making by examining both the distributed processing of information as well as the interaction …

Changing Snowmelt Conditions In The Western Canadian Arctic, Matthew Y. T. Tsui

Theses and Dissertations (Comprehensive)

Multidecadal Changes in Spring Snowmelt in the Western Canadian Arctic

This study investigates the changes in key aspects of snowmelt in the western Canadian Arctic. Specifically, we will look at changes in the onset of snowmelt and the duration of snowmelt between 1999 and 2019, and extended air temperature between 1957 and 2019. In addition, we will look at changes in eight meteorological variables during the melt period. It was found that the onset of snowmelt occurred 14 days earlier, while the melt period ends 20 days earlier than 20 years ago. As a result, the duration of melt period …

Changes In Plant Community Composition, Structure, And Function In Response To Permafrost Thaw, Katherine Standen

Theses and Dissertations (Comprehensive)

Air temperature is increasing at three or more times the global average in high latitudes, causing widespread permafrost thaw across the boreal biome. Since the boreal biome stores 30-40% of global terrestrial carbon (C), of which about 30-45% is found in permafrost soils, this temperature increase could cause a large efflux of C to the atmosphere. Climate warming and permafrost thaw are also expected to alter plant community composition and productivity and, given the link between plant functional traits and ecosystem C fluxes, may alter overall ecosystem function. Across the boreal biome of western Canada, we know surprisingly little about …

Utilization Of The Yamamoto Cyclotrimerization Reaction Towards The Synthesis Of Polycyclic Aromatic Compounds, Josh Ledrew

Theses and Dissertations (Comprehensive)

The overall theme of this research was to synthesize and study the structure-property relationships of novel polycyclic aromatic compounds capable of self-assembling to form liquid crystalline, and microporous structures, as well as molecules capable of molecular recognition. The unifying theme that connects this research is the utilization of the Yamamoto coupling reaction to access the desired polycyclic aromatic hydrocarbon targets. More specifically, the scope of the Yamamoto coupling reaction was explored for the synthesis of electron-deficient triphenylene derivatives that are otherwise difficult to prepare. The molecules prepared via the Yamamoto coupling reaction are expected to be further utilized as intermediates …

Imagining White Victims And Punishing Black Trauma: Whiteness, Anti-Blackness, Trauma, And Social Work In Canadian K-12 Schools, Christine Mayor

Theses and Dissertations (Comprehensive)

This study critically examined how whiteness and anti-Blackness structure Canadian school social workers’ understanding and responses to students’ expressions of trauma in K-12 schools. Very few studies have previously explored the damage that increasingly popular trauma-engaged school programs may be doing, particularly to Black students. Therefore, this study addressed the role that school social workers play in reproducing harm for racialized, and especially Black, students when implementing trauma-engaged practices.

This critical qualitative study used an innovative methodology combining fictional vignettes and semi-structured interview questions with Ontario school social workers (n=19). Data were analyzed using critical whiteness, anti-Blackness, and critical trauma …

Alpine Shrub Tundra Water Storage And Runoff Dynamics In The Mackenzie Mountains, Sahtú Territory, Nt, Geoffrey Kershaw

Theses and Dissertations (Comprehensive)

Alpine regions receive large volumes of precipitation and are important to local and regional water balances, particularly during baseflow periods of winter cold and summer drought when the larger basin area is frozen and/or water limited. Alpine headwaters in western Canada are expected to warm and receive more precipitation during the coming decades, with implications for groundwater recharge and streamflow generation within these systems and the regional river networks to which they contribute. Throughout the North, thawing peat plateaus and other ice-rich permafrost features are resulting in an increased extent of thermokarst and wetland land cover. This transition places infrastructure …

Effects Of 17Α-Ethinylestradiol (Ee2) On Gonadal Development And Gene Expression In Larval Mummichog (Fundulus Heteroclitus), Carly Sing-Judge

Theses and Dissertations (Comprehensive)

The mummichog (Fundulus heteroclitus) is a small-bodied estuarine fish that inhabits the North American east coast and is often used as a model adult saltwater fish in environmental bioassays. This study aimed to describe gonadal development and gene expression levels in five-week-old mummichog under control conditions and following 17α-ethinylestradiol (EE₂) treatment in order to better understand the susceptibility of sex determination (SD) and gonadal differentiation (GD) processes following contaminant exposure. In the first experiment, eggs were fertilized, collected and incubated in the laboratory for three weeks, then yolk-sac larvae were grown out for five weeks and …

Impact Of Orthophosphate As A Corrosion Inhibitor And Chloramine Disinfectant On Drinking Water Biofilm Communities, Mitchell Cooke

Theses and Dissertations (Comprehensive)

A drinking water distribution system (DWDS) must maintain conditions within quality standards which assure the effective and safe transport of finished drinking water from treatment plants to the household tap. Although safe to drink, finished water is not sterile, and may contain hundreds of microorganisms in a single milliliter. These microorganisms are present from the source waters, such as lakes, rivers and aquifers, and have passed through early treatment steps. Final treatment steps, such as the maintenance of disinfectant residuals, are used to further minimize viable cells present and focus on the reduction of harmful organisms. Microbial cells entering the …

The Untended Garden: How Adoptees Navigate Relationships With First Family Members, Dawn Michele Mccormick Tracz

Theses and Dissertations (Comprehensive)

This research explores how people who were adopted over the age of 6 years old in open adoption arrangements navigate ongoing relationships with first family members. It explores perceptions of how a connection with both adoptive and first family members impacts self-concept. Using an interpretivist-constructivist lens, the narratives of four women are presented and analyzed. In addition to qualitative interviews, each participant was invited to create images that represented relationships with significant family members. The narratives are re-presented in detail adhering closely to the teller’s organization and emphases. In the analysis, themes related to relationships with first family members and …

Adrift In Uncharted Waters: A Case Study Of A Muslim Family Involved With Child Protection Services In Ontario, Bibi Baksh

Theses and Dissertations (Comprehensive)

This dissertation sought to understand how Muslims experience mandated child protection services in Ontario within the Canadian (and specifically, Ontarian) socio-political context. Ongoing experiences of racism, xenophobia, and Islamophobia within systems that intersect with child welfare, including schools and the criminal justice system, have compounding effects on Muslim families who are singled out politically and socially. Drawing from trends in child welfare literature, policy initiatives, and practices that consider the system’s impacts upon racialized peoples, this research contributes to the discourse by highlighting religious diversity as an under-investigated source of discrimination. Set against systemic challenges inherent in the child protection …

Exploring Visitor Perceptions And Behaviours Related To Ticks And Lyme Disease Risk In An Ontario Protected Area, Ryan Brady

Theses and Dissertations (Comprehensive)

Lyme disease is the most common vector-borne zoonosis in North America and over the past decade, reported cases of the disease have been rapidly increasing in many regions throughout Canada. The relative novelty of this public health threat presents nature-based tourism and recreation organizations with a range of policy and management challenges. Currently, there is a limited understanding of public perceptions and behaviours associated with tick and Lyme disease risk, especially within a Canadian parks and protected areas visitation and visitor experience context. To address this practical and scholarly knowledge gap, this study utilized in-situ surveys to explore visitor perceptions, …
