Craft A Cold One, Lennon Sullivan, Noah Christy
Craft A Cold One, Lennon Sullivan, Noah Christy
Undergraduate Honors Theses
A demo for a four to five episode mini series on how to brew your own beer at home, with affordable materials. This would help translate very complicated craft brewing techniques into an easy-to-understand guide.
Extirpation Risk Of The Endangered Golden Langur (Trachypithecus Geei) Inside And Outside Biological Corridors, Langthel Sub-District, Trongsa, Central District Bhutan, Kuenzang Dorji
All Master's Theses
I assessed extirpation risks of the golden langur (Trachypithecus geei) in two landscapes (inside and outside the biological corridor). Working with a team of trained scientists, I collected data on group size, feeding range, sleeping sites, and predation on golden langurs from Langthel sub-districts, Trongsa district, central Bhutan. I used scan sampling to follow 24 groups of golden langurs (15 groups outside and 9 groups inside the biological corridor) to estimate average group sizes in the two landscapes. I confirmed their sleeping sites and recorded the physiognomies of sleep sites and dimensions of the trees used as sleeping …
The Relationship Between Eating Disorders, Weight Control Methods, And Body Satisfaction In Elite Female Runners Competing At The 2020 U.S. Olympic Marathon Trials, Sophia Elizabeth Berg
The Relationship Between Eating Disorders, Weight Control Methods, And Body Satisfaction In Elite Female Runners Competing At The 2020 U.S. Olympic Marathon Trials, Sophia Elizabeth Berg
All Master's Theses
The prevalence of eating disorders in athletes is higher than in the general population. Various training styles, weight periodization, and presence of eating disorder (ED) may affect energy availability. This study investigated the relationship between lifetime prevalence of ED with training, body satisfaction, and weight-control methods among elite female endurance athletes. Female runners who participated in the 2020 U.S. Olympic Team Trials Marathon completed an online questionnaire examining training volume, weight-control methods, and self-reported current or past ED. Questions 1-19 were analyzed for this investigation. Participants were grouped according to responses on presence of ED. Thirty-two percent of participants reported …
Cold-Induced Metabolic Changes In Lean, Nag-1 Transgenic Mice, Rachel J. Davey
Cold-Induced Metabolic Changes In Lean, Nag-1 Transgenic Mice, Rachel J. Davey
All Master's Theses
Obesity is a multifaceted metabolic disorder with severe worldwide public health consequences. While obesity can often be treated using diet and exercise, there are complex genetic interactions driving obesity that don’t always respond to such changes. One important research focus for addressing genetic factors is activating brown adipose tissue which increases thermogenesis, the process of burning stored fats to generate heat. Cold exposure is a known way to activate brown adipose tissue through b3-adrenergic signaling. This signaling pathway causes an upregulation of thermogenesis in brown adipocytes and beige adipocytes, which is white adipose tissue that “browns” and becomes metabolically active. …
Ecological And Anthropogenic Influences On A Sentinel Species' Gut Microbiome, Carson E. Black
Ecological And Anthropogenic Influences On A Sentinel Species' Gut Microbiome, Carson E. Black
All Master's Theses
Central and South American primates face augmented challenges due to increased rates of forest fragmentation. Among these challenges are implications on the nonhuman primate gut microbiome. Wild Argentine black and gold howler monkeys (Alouatta caraya) are listed as “least concern” with a population that is decreasing. Despite their propensity to occupy habitats with varying degrees of degradation and disturbance, they are not immune from the stressors that forest fragmentation places on them. Their increased exposure to humans and livestock leaves them vulnerable to cross-species transmission of emerging infectious diseases and pathogens. Therefore, their role as sentinels of ecosystems, …
Patterning And Quality Of Male-Male Interactions In Hamadryas Baboons (Papio Hamadryas), John Calcitrai
Patterning And Quality Of Male-Male Interactions In Hamadryas Baboons (Papio Hamadryas), John Calcitrai
All Master's Theses
The social structure of a primate group is defined as the content, quality, and patterning of interactions and relationships among the members of the social group. Ecological variables, stress physiology, and phylogenetic inertia play a role in regulating measures of interactions and relationships between non-human primates. To examine social dynamics among male hamadryas baboons, video recordings of focal follows of this species were coded for three behavioral categories: self-directed behaviors (SDB), socio-positive behaviors, and agonistic behaviors. The analysis of self-directed behaviors revealed no differences in SDB across males of differing sex classes (i.e., Leader Male, Follower Male, or Solitary Male), …
Development Of Environmental Metabarcoding Analysis For Use In Ecological Studies Of Aquatic Fungal And Oomycete Communities Using Nanopore Sequencing, Douglas Bennett
Development Of Environmental Metabarcoding Analysis For Use In Ecological Studies Of Aquatic Fungal And Oomycete Communities Using Nanopore Sequencing, Douglas Bennett
All Master's Theses
One of several factors contributing to amphibian decline are organisms called water molds (oomycetes), which parasitize and kill amphibian and fish eggs, larvae, and occasionally adults. Amphibian decline is one of the most difficult issues facing ecologists and conservationists to date; half of amphibian species are in severe decline and one third of amphibian species are facing extinction, threatening the stability of ecosystems globally. Multiple oomycete species are known to cause the disease saprolegniasis and contribute to amphibian decline; however, the full range of species involved is not presently known. This study evaluated the Oxford Nanopore minION DNA sequencer (R9.2 …
Comparing Semi-Urban And Forest Populations Of The Jalisco Mud Turtle (Kinosternon Chimalhuaca), Jose Garrido
Comparing Semi-Urban And Forest Populations Of The Jalisco Mud Turtle (Kinosternon Chimalhuaca), Jose Garrido
All Master's Theses
Mud turtles (family Kinosternidae) are primarily threatened by climate change, overexploitation, and land development. To survive in increasingly urbanized and arid regions, mud turtles often inhabit man-made water sources such as cattle troughs and irrigation ditches. These bodies of water are critical in urban habitat where they may offer some of the last remaining refugia; however, the effect of these conditions on population structure is poorly understood. The Jalisco mud turtle (Kinosternon chimalhuaca) was described in 1997 from a small range south of Puerto Vallarta, Mexico. Since its description, critical ecological research has remained largely nonexistent, hindering …
An Ecological Comparison Between Resource Subsidies: Pacific Lamprey (Entosphenus Tridentatus) And Pacific Salmon (Oncorhynchus Spp.), Jocelyn Wensloff
An Ecological Comparison Between Resource Subsidies: Pacific Lamprey (Entosphenus Tridentatus) And Pacific Salmon (Oncorhynchus Spp.), Jocelyn Wensloff
All Master's Theses
Historically, oligotrophic Pacific Northwest (PNW) streams received annual returns of spawning anadromous fish that provided resource subsidies in the form of marine-derived nutrients (MDN), thus driving stream food web productivity. To date, many studies in the PNW have focused on Pacific salmon (Oncorhynchus spp.) as a resource subsidy, overlooking other anadromous fish species such as Pacific lamprey (Entosphenus tridentatus). Both Pacific salmon and Pacific lamprey are culturally important to PNW tribes for ceremonial, medicinal, and subsistence purposes, and have been since time immemorial. Unfortunately, both salmon and lamprey populations are in decline. Historically, lamprey have been disregarded …
