Presence And Distribution Of Leptodactylus Guianensis Heyer And De Sa, 2011 In Colombia: Comparisons With Other Species In The L. Latrans Group., Mariela Osorno Muñoz, Doris L. Gutiérrez-Lamus, Rafael O. De Sá

Biology Faculty Publications

Leptodactylus guianensis is reported for the first time for Colombia along with a distributional map of the species. The species is the fifth species of the L. latransspecies group documented in the country. Males possess a single, conical and slightly chisel-shaped thumb spine; only three species in the group have a single thumb spine. In collections, specimens of L. guianensis are misidentified as L. macrosternum, L. latrans or L. bolivianus. We provide morphological, colouration and habitat descriptions for where the species occurs in Colombia.

The Controversy Of Sexual Violence In The University Setting: Are College Athletes Given A Lighter Sentence Due To Their “Status”, Emma Weber

Honors College Theses

The following paper investigates sexual violence on university campuses. It discusses the role of the Title IX of the Education Amendments of 1972 along with a Dear Colleague Letter enacted by the United States’ federal government to all public institutions regarding how to respond when complaints and allegations of sexual violence are made. The paper addresses the statistics and common misconceptions surrounding sexual violence on college campuses before focusing specifically on student-athletes’ involvement in sexually violent crimes. It then looks into three highly publicized cases where student-athletes are the alleged perpetrators of sexual violence. The three cases analyzed are: the …

How Have Patients' Experiences Of Cancer Care Been Linked To Survival? A Systematic Review, Saleh A. Alessy, Margreet Lüchtenborg Dr, Elizabeth A. Davies Dr.

Patient Experience Journal

Patient experience of care remains an important indicator of health care quality. Although studies show care experiences are associated with health outcomes for some conditions, the situation for cancer is unclear. New datasets on cancer patients in the US, Canada, and UK linking information on experiences and survival may enable an exploration of any association. This review aimed to identify studies linking any aspect of cancer patients’ experiences to their survival, to inform future analyses. We performed a systematic review using Medline database from January 1998 until March 2018.

The settings included outpatient oncology clinics, primary care, hospitals, and cancer …

Synchronicity: The Role Of Midbrain Dopamine In Whole-Brain Coordination, Jeff A. Beeler, Jakob Kiskye Dreyer

Publications and Research

Midbrain dopamine seems to play an outsized role in motivated behavior and learning. Widely associated with mediating reward-related behavior, decision making, and learning, dopamine continues to generate controversies in the field. While many studies and theories focus on what dopamine cells encode, the question of how the midbrain derives the information it encodes is poorly understood and comparatively less addressed. Recent anatomical studies suggest greater diversity and complexity of afferent inputs than previously appreciated, requiring rethinking of prior models. Here, we elaborate a hypothesis that construes midbrain dopamine as implementing a Bayesian selector in which individual dopamine cells sample afferent …

Nebraska Strong - Social Capital In Action, Marilyn R. Schlake

Cornhusker Economics

We have heard it and we have witnessed it in action. Nebraska Strong has been a unifying message that is bringing Nebraskans, friends and family together from across the nation. Signifying strength, determination, and a resolve to rebuild, Nebraska Strong has bolstered communities and individuals who have, in some cases, lost all semblance of what they had prior to the disastrous March blizzard and floods. Through this simple message, individuals have begun to utilize their social group networks or social capital to support recovery efforts.

Through the study of communities that have experienced major disasters, researchers found the existence of …

Impact Of Heart Rate Intensity On Shooting Accuracy During Games In Ncaa Division I Women Basketball Players, James Hutson, Courtney Elliott, Casey Pederson

Undergraduate Research Conference

Shooting accuracy in basketball is key to winning games. While there are various factors as to why a team either makes or misses their shots, the intensity of play is likely a contributing factor. A player who has played the majority of the game would likely have a higher, more intense heart rate (HR). Depending on the athlete, this could impact shooting accuracy. Examining the relationship between HR intensity and shooting accuracy has not been looked at in a real game setting before. Therefore, we set out to determine the impact heart rate intensity has on shooting accuracy in a …

Comparison Of Heart Rate Intensity In Practice, Conditioning, And Games In Ncaa Division I Women Basketball Players, Courtney Elliott, Casey Pederson, James Hutson

Undergraduate Research Conference

Background: An athlete’s heart rate (HR) is an important variable in quantifying the intensity of exercise. Workouts that increase HR are an important stimulus for training adaptations and conditioning. At other times, workouts that do not overly stress the HR may be desired to allow for recovery. The principle of specificity emphasizes that athletes should train specific to the way they will need to perform in competition. Because of this, monitoring HR during training and competition can be a useful tool. While exercise intensity in endurance sports has been previously investigated, less is known regarding the HR response in team …

Reduced-Impact Logging For Climate Change Mitigation (Ril-C) Can Halve Selective Logging Emissions From Tropical Forests, Anand Roopsind

Biology Faculty Publications and Presentations

Selective logging causes at least half of the emissions from tropical forest degradation. Reduced-impact logging for climate (RIL-C) is proposed as a way to maintain timber production while minimizing forest damage. Here we synthesize data from 61 coordinated field-based surveys of logging impacts in seven countries across the tropics. We estimate that tropical selective logging emitted 834 Tg CO₂ in 2015, 6% of total tropical greenhouse gas emissions. Felling, hauling, and skidding caused 59%, 31%, and 10% of these emissions, respectively. We suggest that RIL-C incentive programs consider a feasible target carbon impact factor of 2.3 Mg emitted per …

Mixed Mood State Behaviors And Circadian Dysfunction Following Homocysteic Acid Treatment: Potential Animal Model For Bipolar Disorder, Lauren Evert, Gonzalo Moya, Ryann Felton, Garrett Fogo, Nicholas Rozema, Sarah Plowman, Tymi Staub

18th Annual Celebration of Undergraduate Research and Creative Activity (2019)

Bipolar disorder is a neuropsychiatric disease characterized by cyclical fluctuations of mood states between mania and depression. Circadian rhythm abnormalities and inconsistent sleep patterns are two common symptoms of bipolar disorder (Millar, Epsie, & Scott, 2004). Elevated levels of homocysteine, in the blood or cerebrospinal fluid, commonly occurs in patients with neuropsychiatric illnesses, including bipolar disorder (Bell et al., 1992; Boushey, Beresford, Omenn, & Motulsky, 1995). Homocysteic acid (HCA), an endogenous metabolite of homocysteine, has been implicated as a harmful neurotoxin and agonist of NMDA receptors. We have previously shown that postnatal administration of HCA (from postnatal day 3-21) in …

Testing The Impact Of Prebiotics On Anxiety-Like Behaviors In Aged Male Rats, Nicholai Shaw, Marny Ehmann, Kenia Urena-Gonzalez, Anna Langholz, Peter Stewart, Jared Stygstra, Emily Zolman, Erin English, Alli Lindquist, Elizabeth Woodford

18th Annual Celebration of Undergraduate Research and Creative Activity (2019)

The composition of gut microbiota has direct impacts on neural structure, neurochemistry, and behavior. Specifically, the gut microbiota has been shown to modulate anxiety-like behaviors. In addition, administering prebiotics, compounds that promote the growth of commensal bacteria, has been demonstrated to reduce anxiety and anxiety-related behaviors. However, this effect has yet to be tested in older animals despite anxiety being implicated as a most common disorder in adult populations. Therefore, this study seeks to fill this knowledge gap by investigating the link between prebiotic interventions and anxiety-like behaviors in aged populations. It was hypothesized that older rats treated with the …

The Serial Blocking Effect: A Testbed For The Neural Mechanisms Of Temporal-Difference Learning, Ashraf Mahmud, Petio Petrov, Guillem R. Esber, Mihaela D. Iordanova

Publications and Research

Temporal-difference (TD) learning models afford the neuroscientist a theory-driven roadmap in the quest for the neural mechanisms of reinforcement learning. The application of these models to understanding the role of phasic midbrain dopaminergic responses in reward prediction learning constitutes one of the greatest success stories in behavioural and cognitive neuroscience. Critically, the classic learning paradigms associated with TD are poorly suited to cast light on its neural implementation, thus hampering progress. Here, we present a serial blocking paradigm in rodents that overcomes these limitations and allows for the simultaneous investigation of two cardinal TD tenets; namely, that learning depends on …

Evolution Of Endurance Running Genes Across Primates, Natalia T. Grube

Theses and Dissertations

The endurance running hypothesis has emerged as a key idea to explain several unique anatomical, physiological, and genetic features of modern humans—among these features is the evolution of ACTN3 (Bramble & Lieberman 2004, Nature), a gene linked to human athletic performance. An additional gene linked to human endurance performance is ACE. Because endurance running is a uniquely human trait, I predicted that ACE and ACTN3 genes would be evolving adaptively in the human lineage when examined in a wider primatological framework. To test this I compiled ACE and ACTN3 genes from 14 primate species and phylogenetically tested if these genes …

Nutrient And Food Group Intakes Of Low-Income Pregnant Women By Race/Ethnicity, Alla M. Hill, Danielle L. Nunnery Phd, Rdn, Ldn, Alice Ammerman Drph, Jigna M. Dharod Phd

Publication Reform To Safeguard Wildlife From Researcher Harm, Kate A. Field, Paul C. Paquet, Kyle A. Artelle, Gilbert Proulx, Ryan K. Brook, Chris T. Darimont

Professional Science Research Ethics Collection

Despite abundant focus on responsible care of laboratory animals, we argue that inattention to the maltreatment of wildlife constitutes an ethical blind spot in contemporary animal research. We begin by reviewing significant shortcomings in legal and institutional oversight, arguing for the relatively rapid and transformational potential of editorial oversight at journals in preventing harm to vertebrates studied in the field and outside the direct supervision of institutions. Straightforward changes to animal care policies in journals, which our analysis of 206 journals suggests are either absent (34%), weak, incoherent, or neglected by researchers, could provide a practical, effective, and rapidly imposed …

Age Status Effects On Female Silk Production And Male Courtship Response In Dolomedes Scriptus, Joseph Osborne

Student Scholar Showcase

Female Dolomedes scriptus, the striped fishing spider, serve as model organisms exhibiting pheromone production as a means of chemical signaling. Previous work has shown that male fishing spiders are responsive to female silk, and preferentially court in the presence of silk from mature virgins. In our research, we hypothesized that mature females produced larger quantities of silk than penultimate females in an attempt to elicit greater male mating response. Female spiders of both age statuses were kept for two days in a gridded tank. Sub-sampling of silk lines that crossed a random portion of the grid produced results signifying …

The Impact Of Different Data Processing Methods On Site-Specific Management Recommendation, Taro Mieno, Joe D. Luck, Zhengzheng Gao

Cornhusker Economics

Precision agriculture has the potential to enhance farming profitability substantially via site-specific management of fields. One of the promising ways of generating such profitability-enhancing input is to a use recommendation map is on-farm randomized trials. The process of generating an input (say nitrogen) using a recommendation map typically involves the following steps:

1. Design and implement randomized input use trial

2. Collect yield data along with other field characteristics (Slope, Electrical Conductivity, and Organic Matter)

3. Process the data for statistical analysis

4. Conduct regression analysis to estimate production function (how the input affect crop yield)

5. For each of …
