Temporal And Spatial Distribution Of Enterobius Vermicularis (Nematoda: Oxyuridae) In The Prehistoric Americas, Karl J. Reinhard, Adauto Araújo, Johnica J. Morrow

Karl Reinhard Publications

Investigations of Enterobius sp. infection in prehistory have produced a body of data that can be used to evaluate the geographic distribution of infection through time in the Americas. Regional variations in prevalence are evident. In North America, 119 pinworm positive samples were found in 1,112 samples from 28 sites with a prevalence of 10.7%. Almost all of the positive samples came from agricultural sites. From Brazil, 0 pinworm positive samples were found in 325 samples from 7 sites. For the Andes region, 22 pinworm positive samples were found in 411 samples from 26 sites for a prevalence of 5.3%. …

Governing common pool resources (CPR) in the face of disturbances such as globalization and climate change is challenging. The outcome of any CPR governance regime is the influenced by local combinations of social, institutional, and biophysical factors, as well as cross-scale interdependencies. In this study, we take a step towards understanding multiple-causation of CPR outcomes by analyzing 1) the co-occurrence of Destign Principles (DP) by activity (irrigation, fishery and forestry), and 2) the combination(s) of DPs leading to social and ecological success. We analyzed 69 cases pertaining to three different activities: irrigation, fishery, and forestry. We find that the importance …

An Iterative Approach To Large-N Case Studies: Insights From Qualitative Analysis Of Quantitative Inconsistencies, Allain J. Barnett, Jacopo A. Baggio, Hoon C. Shin, David J. Yu, Irene Perez-Ibarra, Cathy Rubiños, Ute Brady, Elicia Ratajczyk, Nathan Rollins, Rimjhim Aggarwal, John M. Anderies, Marco A. Janssen

Large-N comparative studies have helped common pool resource scholars gain general insights into the factors that influence collective action and governance outcomes. However, these studies are often limited by missing data, and suffer from the methodological limitation that important information is lost when we reduce textual information to quantitative data. This study was motivated by nine case studies that appeared to be inconsistent with the expectation that the presence of Ostrom’s Design Principles increases the likelihood of successful common pool resource governance. These cases highlight the limitations of coding and analysing Large-N case studies. We examine two issues: 1) the …

On-going efforts to understand the dynamics of coupled social-ecological (or more broadly, coupled infrastructure) systems and common pool resources have led to the generation of numerous datasets based on a large number of case studies. This data has facilitated the identification of important factors and fundamental principles which increase our understanding of such complex systems. However, the data at our disposal are often not easily comparable, have limited scope and scale, and are based on disparate underlying frameworks inhibiting synthesis, meta-analysis, and the validation of findings. Research efforts are further hampered when case inclusion criteria, variable definitions, coding schema, and …

Survey Of Nematodes Associated With Terrestrial Slugs In Norway, J. L. Ross, E. S. Ivanova, B. A. Hatteland, M. B. Brurberg, S. Haukeland

All Peer-Reviewed Publications

A survey of nematodes associated with terrestrial slugs was conducted for the first time in Norway. A total of 611 terrestrial slugs were collected from 32 sample sites. Slugs were identified by means of morphological examination, dissection of genitalia and molecular analysis using mitochondrial DNA. Twelve slug species were identified, representing four different slug families. Internal nematodes were identiï¬'d by means of morphological analysis and the sequencing of the 18S rRNA gene. Of the sample sites studied, 62.5% were found to be positive for nematode parasites, with 18.7% of all slugs discovered being infected. Five nematode species were identified in …

Changes In Job Satisfaction Through Time In Two Major New England Fishing Ports, Tarsila Seara, Richard Pollnac, John J. Poggie

Biology and Environmental Science Faculty Publications

Fishing communities in the U.S. have been the subject of great transformation due to changes in availability of resources and the implementation of different rules and regulations to manage the fisheries and conserve fish stocks. Job satisfaction has been widely regarded as an important component of well-being especially among fishermen because the occupation of fishing includes attributes of ‘adventure,’ ‘challenge,’ and ‘being outdoors’ infrequently found in other employment. It has been previously demonstrated that management driven changes to fishing communities can directly and indirectly affect aspects of fishermen’s job satisfaction and, consequently, their wellbeing. This paper presents a unique through …

Global Intron Retention Mediated Gene Regulation During Cd4+ T Cell Activation., Ting Ni, Wenjing Yang, Miao Han, Yubo Zhang, Ting Shen, Hongbo Nie, Zhihui Zhou, Yalei Dai, Yanqin Yang, Poching Liu, Kairong Cui, Zhouhao Zeng, Yi Tian, Bin Zhou, Gang Wei, Keji Zhao, Weiqun Peng, Jun Zhu

Genomics and Precision Medicine Faculty Publications

T cell activation is a well-established model for studying cellular responses to exogenous stimulation. Using strand-specific RNA-seq, we observed that intron retention is prevalent in polyadenylated transcripts in resting CD4(+) T cells and is significantly reduced upon T cell activation. Several lines of evidence suggest that intron-retained transcripts are less stable than fully spliced transcripts. Strikingly, the decrease in intron retention (IR) levels correlate with the increase in steady-state mRNA levels. Further, the majority of the genes upregulated in activated T cells are accompanied by a significant reduction in IR. Of these 1583 genes, 185 genes are predominantly regulated at …

A Quantitative Analysis Of Hugelkultur And Its Potential Application On Karst Rocky Desertified Areas In China, Megan Laffoon

Mahurin Honors College Capstone Experience/Thesis Projects

A type of environmental degradation, karst rocky desertification (KRD) refers to areas where the soil loss exposes the bedrock and reduces the land’s ability to sustain life and is particularly widespread through the vast karst area of rural southwest China. Hugelkultur is a permaculture method that harnesses the wood decomposition process by burying logs beneath soil. We proposed that hugel beds will demonstrate a higher water holding capacity and enhance soil development, in a way that may show promise as a potential method to help alleviate problems of KRD. Soil samples were taken from hugel plots, non-hugel plots, and KRD-like …

Who Is A Person? Whoever You Want It To Be, Gwen J. Broude

Animal Sentience

Rowlands provides an expanded definition of personhood that preserves the requirement of unity of mental life from the orthodox definition but argues that implicit unity of mind is sufficient for conferring personhood. This allows more or all animals to be considered persons. Implicit unity of mind may be a bridge too far for those who endorse the orthodox account of personhood, and for good reasons. More fundamentally, who gets to decide what personhood entails or that personhood per se matters to such other issues as who receives legal or moral status and consideration? Perhaps we should worry less about definitions …

Cryptosporidium Parvum Among Coprolites From La Cueva De Los Muertos Chiquitos (600–800 Ce), Rio Zape Valley, Durango, Mexico, Johnica J. Morrow, Karl Reinhard

Karl Reinhard Publications

In the present study, 90 coprolites from La Cueva de los Muertos Chiquitos (CMC) were subjected to enzyme-linked immunosorbent assay (ELISA) tests for 3 diarrhea-inducing protozoan parasites, Entamoeba histolytica, Giardia duodenalis, and Cryptosporidium parvum, to determine whether these parasites were present among the people who utilized this cave 1,200–1,400 yr ago. These people, the Loma San Gabriel, developed as a culture out of the Archaic Los Caracoles population and lived throughout much of present-day Durango and Zacatecas in Mexico. The Loma San Gabriel persisted through a mixed subsistence strategy of hunting-gathering and agricultural production. The results of …

Effect Of Migration, Carrying Capacity, And Fecundity On The Formation Of Clinal Patterns During Range Expansions., Neha J. Angal

Electronic Theses and Dissertations

Range expansions, empirically and in simulations, lead to clinal patterns of genetic diversity. Clines are often used as spatial markers of past migrations. This study investigated the effects of migration, growth, and carrying capacities on clinal patterns during range expansions, using forward-time simulations in Nemo. Initial results show, in the absence of prior population structure, range expansions result in a loss of diversity strongly affected by migration, growth, and carrying capacity. This loss of diversity did not persist to the final generation, corresponding to 10,000 years, indicating clinal patterns are less durable than previously assumed—challenging the utility of clinal patterns …

An Inquiry Into The Pedagogical Implications Of Dewey’S Ecological Thinking, Simon Jorgenson

From the foods we eat and the houses we construct, to our religious practices and political organization, to who we can marry and the types of games we teach our children, the diversity of cultural practices in the world is astounding. Yet, our ability to visualize and understand this diversity is limited by the ways it has been documented and shared: on a culture-by-culture basis, in locally-told stories or difficult-to-access repositories. In this paper we introduce D-PLACE, the Database of Places, Language, Culture, and Environment. This expandable and open-access database (accessible at https://d-place.org) brings together a dispersed corpus of …

Effects Of Multilevel Selection On The Evolution Of Homo Neandertalensis, Tracey Renee Lancaster

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

In this article, a model is used based on a paper by E. O. Wilson et al. (2007) to examine how multilevel selection has affected the evolution of Neandertals. Multilevel selection theory states natural selection occurs in multiple levels of the biological hierarchy. This model has never been applied to a hominid species to date. By synthesizing this research by Wilson et al. and genetic studies by Green et al. (2010) revealing that Neandertals and humans interbred in the Middle East 80,000 years ago, it is shown that multilevel selection may have affected Neandertal evolution. Further, it is argued that …

Alcohol Discrimination And Preferences In Two Species Of Nectar-Feeding Primate, Samuel R. Gochman, Michael B. Brown, Nathaniel J. Dominy

Dartmouth Scholarship

Recent reports suggest that dietary ethanol, or alcohol, is a supplemental source of calories for some primates. For example, slow lorises (Nycticebus coucang) consume fermented nectars with a mean alcohol concentration of 0.6% (range: 0.0–3.8%). A similar behaviour is hypothesized for aye-ayes (Daubentonia madagascariensis) based on a single point mutation (A294V) in the gene that encodes alcohol dehydrogenase class IV (ADH4), the first enzyme to catabolize alcohol during digestion. The mutation increases catalytic efficiency 40-fold and may confer a selective advantage to aye-ayes that consume the nectar of Ravenala madagascariensis. It is uncertain, however, whether alcohol exists in this nectar …

Coping with Water Scarcity in River Basins Worldwide: Lessons Learned from Shared Experiences (Martz Summer Conference, June 9-10)

Water scarcity is increasingly dominating headlines throughout the world. In the southwestern USA, the looming water shortages on the Colorado River system and the unprecedented drought in California are garnering the greatest attention. Similar stories of scarcity and crisis can be found across the globe, suggesting an opportunity for sharing lessons and innovations. For example, the Colorado River and Australia's Murray-Darling Basin likely can share many lessons, as both systems were over-allocated, feature multiple jurisdictions, face similar climatic risks and drought stresses, and struggle to balance human demands with environmental needs. In this conference we cast our net broadly, exploring …

Human Locomotion: Examining Energy Costs And Human Behavior Associated With Load-Carrying, Gailynn Benjamin

Honors Projects

The energy expenditure during load-carrying depends on the mass of the load, the position of the load on the body, and if tools are used to help transfer the load. When the load being carried is a human child, strategies employed to cope with the increased energetic burden should include males carrying older and heavier children, arm use decreasing as children become older, and tool use increasing as children become older. To uncover whether people make energetically-mediated decisions to carry children, 236 adult males and 314 adult females were observed walking around parks in Seattle, WA, while carrying a child. …

Agenda: Indigenous Water Justice Symposium, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

Indigenous Water Justice Symposium (June 6)

Indigenous peoples throughout the world face diverse and often formidable challenges of what might be termed “water justice.” On one hand, these challenges involve issues of distributional justice that concern Indigenous communities’ relative abilities to access and use water for self-determined purposes. On the other hand, issues of procedural justice are frequently associated with water allocation and management, encompassing fundamental matters like representation within governance entities and participation in decision-making processes. Yet another realm of water justice in which disputes are commonplace relates to the persistence of, and respect afforded to, Indigenous communities’ cultural traditions and values surrounding water—more specifically, …

A Semi-Automated Algorithm For Segmenting The Hippocampus In Patient And Control Populations, Nathan Mckay Muncy

Theses and Dissertations

Calculating hippocampal volume from Magnetic Resonance (MR) images is an essential task in many studies of neurocognition in healthy and diseased populations. The `gold standard' method involves hand tracing, which is accurate but laborious, requiring expertly trained researchers and significant amounts of time. As such, segmenting large datasets with the standard method is impractical. Current automated pipelines are inaccurate at hippocampal demarcation and volumetry. We developed a semi-automated hippocampal segmentation pipeline based on the Advanced Normalization Tools (ANTs) suite of programs to segment the hippocampus. We applied the semi-automated segmentation pipeline to 70 participant scans (26 female) from groups that …

Producing Knowledge: The Social Made Visible In The Division Of Environmental Biology Of The National Science Foundation, Patrick Southern

Capstone Collection

This inquiry explores how knowledge is produced in the Division of Environmental Biology (DEB) of the National Science Foundation. Beginning from a poststructuralist understanding of science as firmly embedded in the unequal relations of society, this study sought to examine how the policies and procedures of funding research proposals in DEB influence and are influenced by those relations. Using an institutional ethnography approach to analysis, data were collected from analyzing publicly available texts from the division, NSF, Congress, the Office of Management and Budget, and the research community. The analysis demonstrates how the activities of DEB could maintain or exacerbate …
