Pakootas V. Teck Cominco Metals, Ltd., Connlan W. Whyte

Public Land & Resources Law Review

Throughout the twentieth century, Teck Cominco Metals leaked metal pollutants into the Upper Columbia River that ultimately entered the United States and the Colville Indian Reservation. In 2004, after almost a decade of working with the United States Environmental Protection Agency, the Colville Tribes initiated a citizen suit under CERCLA against Teck for damaging the ecosystem of the Upper Columbia River. In 2018, the Ninth Circuit affirmed judgment against Teck for recovery costs and attorney’s fees.

Understanding The Perceptions Of Threats And Risks People Have Towards Wildlife, Paige King

University of Montana Conference on Undergraduate Research (UMCUR)

Human-wildlife interactions occur in an array of settings. In Yellowstone National Park and surrounding areas, a major issue is visitors approaching wildlife. This is a concern for the safety of visitors and wildlife, visitor experience, and preservation of natural and cultural values of the National Park. The goal of the study is to understand the thought process behind trying to approach wildlife. Knowing the threats and the potentials risks of approaching wildlife generally influences decision making when encountering wildlife. Emotional connections people have regarding wildlife may also have a significant impact on their decision-making process. Visitors are likely to have …

Does Relative Condition Predict Probability Of Spawning And Post-Spawning Mortality For A Migratory Inland Trout?, Maggie Wallace

University of Montana Conference on Undergraduate Research (UMCUR)

Fluvial Westslope Cutthroat Trout (Oncorhynchus clarkii lewisi) occupy a variety of river habitats over their life, moving long distances in order to complete their life history. Despite being iteroparous, individual Westslope Cutthroat Trout have high mortality associate with spawning and may skip spawning some years. We hypothesized that initial body condition at tagging is positively related to probability of spawning, migration distance, and post-spawning mortality. Additionally, we expect distance moved upstream may explain variation in post-spawning survival. We used radio telemetry to track movements of 70 non-hybridized Westslope Cutthroat Trout greater than 350mm in Rock Creek, Montana from …

Genetic Analysis Of Changes In Body Length In Caenorhabditis Elegans, Mikaya Terzo

University of Montana Conference on Undergraduate Research (UMCUR)

The regulation of the cell cycle is an essential process that contributes to the normal growth and division as well as the prevention of tumor formation. A cell’s progress through mitosis is regulated by a network of proteins that affect the cyclin B–Cdk1 complex. In C. elegans, there are 4 different cyclin B genes that partner with Cdk1: cyb-1, cyb-2.1, cyb-2.2, and cyb-3. Although all are required for completion of embryonic cell divisions, the detailed functions of some of these cyclins, including any contribution to the regulation of animal size, are still unknown. After noticing a …

The Evolution Of Dragons, Laura Janelle Mayfield

University of Montana Conference on Undergraduate Research (UMCUR)

Dragons have been depicted in human art as early as 4500 BCE. For centuries, these fantasy creatures have inspired countless folk and fantasy tales, as well as appearing in the art of different cultures around the world. Now there are thousands of different depictions of these huge, flying, fire-breathing lizards, but are any of them plausible? In this study, I referenced peer-reviewed scientific articles, phylogenetic analysis, and paleoart studies to create biologically-sound dragons. Basing the dragon lineage on a real branch of webbed-winged scansoriopterygids—an extinct family of climbing and gliding maniraptoran dinosaurs—I explored the possible wing-structure, fire-breathing abilities, and effects …

Behavioral Impacts Of The Gut Microbiome On Drosophila Melanogaster, Ashley May Bielawski

University of Montana Conference on Undergraduate Research (UMCUR)

Recent studies indicate alterations in the gut microbiome impact behavior including increasing aggressive behavior. The gut of an organism is home to a complex community of bacteria, fungi and viruses that collectively make up the gut microbiome. The prevailing hypothesis is that changes in the microbiome are communicated to the brain and subsequently impact behavior. In the Certel lab, we are identifying factors that regulate aggressive behavior and have been specifically examining the role of octopamine using the model system Drosophila. Octopamine (OA) is a neurotransmitter and neuromodulator that is required to promote aggression. Males without OA exhibit decreased …

Singing Beetles? Figuring Out How Male Rhinoceros Beetles Produce Their Courtship Songs., Devin Hunt, Nathan Barton, Chelsey Caldwell, Cole Sander, Romain Boisseau, Cerisse Allen, Douglas J. Emlen

University of Montana Conference on Undergraduate Research (UMCUR)

Insects produce sound in wildly-diverse ways, from the vibrating wings of chirping crickets to the pulsating tympanum of whining of cicadas. Beetles (order: Coleoptera) use sound in aggressive displays, alarm calls, and courtship sequences. Although all beetles appear to generate sounds using stridulation, where a plectrum, or pick, is rubbed against a pars stridens, or file, species differ in the size and location of these structures, resulting in a diverse mechanistic array of sound production within this order. The Japanese rhinoceros beetle, Trypoxylus dichotomus, was recently observed stridulating during courtship sequences; however, the mechanism of sound production, including …

Tax Burdens And Tribal Sovereignty: The Prohibition On Lavish And Extravagant Benefits Under The Tribal General Welfare Exclusion, Pippa Browde

Faculty Law Review Articles

This article examines a portion of a relatively new federal tax statute, the Tribal General Welfare Exclusion (TGWE), that allows qualified individuals an exclusion from gross income for payments received from American Indian/Alaska Native tribes for any "Indian general welfare benefit." Indian general welfare benefits are payments made to tribal members by the tribe pursuant to an Indian tribal government program for the promotion of general welfare, such as for health, education, or housing. The TGWE is intended, in part, to promote participation in American Indian tribal cultural and ceremonial practices. To that end, Indian general welfare benefits include payments …

Navajo Nation V. United States Department Of The Interior, Adam W. Johnson

Public Land & Resources Law Review

The Navajo Nation sued the United States government alleging the government breached its trust obligation over the allocation of water rights in the Colorado River Basin. On remand, the district court denied the Navajo Nation leave to file its third amended complaint for futility, holding that the general trust relationship was insufficient to support the Nation’s breach of trust claim.

Is It Human? Engaging In The Academic And Forensic Applications Of Zooarchaeology, Haley O'Brien

UM Graduate Student Research Conference (GradCon)

Zooarchaeology is the study and identification of animal skeletal remains and their relationship with human interaction. It is a heavily methodologically based, world-wide discipline that can be uniquely tailored to the context and research question of the archaeological site/region under review. It requires a significant amount of hands-on training in order to identify bone fragments to the most specific species level and element possible using the size, shape, and density of the remains. When expanding the analyst’s view to the other variables that can be considered, measures such as burning, cut marks, tooth marks, and fracture types can build a …

Fish On Fluoxetine: Before, During, And After, Susan Greene

UM Graduate Student Research Conference (GradCon)

Wastewater pollution contaminating surface waters has become a concern all over the world, even in places humans don’t permanently live. These contaminants come from a variety of chemicals, such as anti-depressants, and the effects vary between species. Unfortunately, methods for extraction of these chemicals from wastewater are not economical and cheaper alternatives are still being developed. This has led to an increase in chemicals in surface water, with antidepressants increasing 400 percent in recent decades. This increase in chemicals in surface water could have impacts on the creatures inhabiting the polluted water. Few studies have been conducted on what impact …

Time To Return-To-Play Post Anterior Cruciate Ligament Reconstruction In Female Soccer Players: A Systematic Review, Lucas Bonnevie

UM Graduate Student Research Conference (GradCon)

Context: Compared to men, female athletes are up to ten times more likely to rupture their anterior cruciate ligament while playing soccer, a major stabilizer in the knee. These athletes undergo anterior cruciate ligament reconstruction (ACLR) and return-to-play (RTP) rehabilitation protocols; however, previous research on RTP has been limited to addressing individual underlying factors. This systematic review aims to use a more holistic approach and provide insights on which factors affect the overall RTP timeframe of female soccer athletes post ACLR, and in turn provide healthcare professionals with more certainty in return-to-play timeframes in female soccer players. Methods: A systematic …

On The Complexity Of Conceptual Animal Metaphors In Queer Speech, Jarrett Hopewell

UM Graduate Student Research Conference (GradCon)

For English speaking members of the queer community in the United States, there is a group of animal terms used to categorize different “tribes” of community members. For example, the term bear generally refers to an individual who is large, hairy, and older. Samardžić (2015) proposes these animal terms as the conceptual metaphor: GAYS ARE ANIMALS. In cognitive linguistics, conceptual metaphor refers to the understanding of an abstract concept in terms of a concrete source. In other words, the different “tribes” of queer community members are conceptually understood in terms of animals.

Departing from Samardžić (2015), the present author proposes …

A New Classification System For Analyzing Burned Human Remains, Amanda Williams

UM Graduate Student Research Conference (GradCon)

Fires can alter human remains in various ways; however, complete destruction of a human body by burning is impossible and skeletal remains can almost always be recovered. Fatal fires produce a range of physical alterations to the body, from blistering of soft tissue to the calcination of bones.Theses physical alterations leave patterns that can be studied and analyzed to interpret perimortem events. A variety of forensic professionals interact with and analyze these remains postmortem, which can lead to variation in how remains are described.

Currently, the forensic community lacks a consistent, objective, and detailed scale to describe burn injuries or …

Structure Of The G Protein Chaperone And Guanine Nucleotide Exchange Factor Ric-8a Bound To Gαi1, Levi J. Mcclelland, Kaiming Zhang, Tung-Chung Mou, Jake Johnston, Cindee Yates-Hansen, Shanshan Li, Celestine J. Thomas, Tzanko I. Doukov, Sarah Triest, Alexandre Wohlkonig, Gregory G. Tall, Jan Steyaert, Wah Chiu, Stephen Sprang

Biological Sciences Faculty Publications

Ric-8A is a cytosolic Guanine Nucleotide exchange Factor (GEF) that activates heterotrimeric G protein alpha subunits (Gα) and serves as an essential Gα chaperone. Mechanisms by which Ric-8A catalyzes these activities, which are stimulated by Casein Kinase II phosphorylation, are unknown. We report the structure of the nanobody-stabilized complex of nucleotide-free Gα bound to phosphorylated Ric-8A at near atomic resolution by cryo-electron microscopy and X-ray crystallography. The mechanism of Ric-8A GEF activity differs considerably from that employed by G protein-coupled receptors at the plasma membrane. Ric-8A engages a specific conformation of Gα at multiple interfaces to form a complex that …
