Clayton, Anneke Moresco, Erin A. Mckenney, Larry J. Minter, Mallory J. Suhr Van Haute, William Gasper, Shivdeep Singh Hayer, Lifeng Zhu, Kathryn Cooper, Kimberly Ange-Van Heugten

Department of Food Science and Technology: Faculty Publications

The last few decades have seen an outpouring of gastrointestinal (GI) microbiome studies across diverse host species. Studies have ranged from assessments of GI microbial richness and diversity to classification of novel microbial lineages. Assessments of the “normal” state of the GI microbiome composition across multiple host species has gained increasing importance for distinguishing healthy versus diseased states. This study aimed to determine baselines and trends over time to establish “typical” patterns of GI microbial richness and diversity, as well as interindividual variation, in three populations of western lowland gorillas (Gorilla gorilla gorilla) under human care at three …

Interspecies Variation In Hominid Gut Microbiota Controls Host Gene Regulation, Amanda L. Muehlbauer, Allison L. Richards, Adnan Alazizi, Michael B. Burns, Andres Gomez, Jonathan B. Clayton, Klara Petrzelkova, Camilla Cascardo, Justyna Resztak, Xiaoquan Wen, Roger Pique-Regi, Francesca Luca, Ran Blekhman

The gut microbiome exhibits extreme compositional variation between hominid hosts. However, it is unclear how this variation impacts host physiology across species and whether this effect can be mediated through microbial regulation of host gene expression in interacting epithelial cells. Here, we characterize the transcriptional response of human colonic epithelial cells in vitro to live microbial communities extracted from humans, chimpanzees, gorillas, and orangutans. We find that most host genes exhibit a conserved response, whereby they respond similarly to the four hominid microbiomes. However, hundreds of host genes exhibit a divergent response, whereby they respond only to microbiomes from specific …

The International Scientific Association For Probiotics And Prebiotics (Isapp) Consensus Statement On Fermented Foods, Maria L. Marco, Mary Ellen Sanders, Michael Gänzle, Marie Claire Arrieta, Paul D. Cotter, Luc De Vuyst, Colin Hill, Wilhelm Holzapfel, Sarah Lebeer, Dan Merenstein, Gregor Reid, Benjamin E. Wolfe, Robert Hutkins

Department of Food Science and Technology: Faculty Publications

An expert panel was convened in September 2019 by The International Scientific Association for Probiotics and Prebiotics (ISAPP) to develop a definition for fermented foods and to describe their role in the human diet. Although these foods have been consumed for thousands of years, they are receiving increased attention among biologists, nutritionists, technologists, clinicians and consumers. Despite this interest, inconsistencies related to the use of the term ‘fermented’ led the panel to define fermented foods and beverages as “foods made through desired microbial growth and enzymatic conversions of food components”. This definition, encompassing the many varieties of fermented foods, is …

Genetic Variability And Evolutionary Dynamics Of Atypical Papaya Ringspot Virus Infecting Papaya, Anam Saleem, Zahid Ali, Shyi-Dong Yeh, Wajeeha Saeed, Amna Binat Imdad, Muhammad Faheem Akbar, Richard E. Goodman, Saadia Naseem

Department of Food Science and Technology: Faculty Publications

Papaya ringspot virus biotype-P is a detrimental pathogen of economically important papaya and cucurbits worldwide. The mutation prone feature of this virus perhaps accounts for its geographical dissemination. In this study, investigations of the atypical PRSV-P strain was conducted based on phylogenetic, recombination and genetic differentiation analyses considering of it’s likely spread across India and Bangladesh. Full length genomic sequences of 38 PRSV isolates and 35 CP gene sequences were subjected to recombination analysis. A total of 61 recombination events were detected in aligned complete PRSV genome sequences. 3 events were detected in complete genome of PRSV strain PK whereas …

Conflict Resolution In A Multi-Level It-Enabled Outsourcing Network: A Structured Solution Approach, Shreekant Vijaykar, Mahesh Gupta Prof., Pradip Kumar Bhaumik Dr.

Journal of International Technology and Information Management

Using the case study of an Indian Technology and Outsourcing Service Provider, SmartKey (real but renamed company), a technology vendor to a global healthcare provider, this paper analyses offshore outsourcing issues using IT-enabled services to gain deeper insights needed to understand the core conflict and propose a well-reasoned solution approach. Reasoning, the conscious thought process leading to a well-justified decision, is an important managerial skill required for making dynamic decisions, resolving conflicts, and thereby developing human resources. This paper explores Goldratt’s Evaporating Clouds (ECs) as a systematic approach to reasoning in particular, and as a system for developing human resource …

Digital Divide Of Perceptions, Usage, And Purchase Items In Japanese E-Payment Adoption, Michael E. Ellis, Moe Ota, Alexander N. Chen

Journal of International Technology and Information Management

The idea of a “digital divide” is a common issue in less developed countries but is also found in developed countries. We surveyed 151 Japanese to examine the effect of digital divide characteristics such as regional variations, age, and gender on the perception and behavior surrounding e-payments.

We find that regional difference affects Japanese perceptions, especially ease of use and trust, but not use. Also, older people are more like to use e-payment in terms of weekly frequency and amount of money spent than younger consumers. Japanese males, in general, have higher average scores in ease of use, importance of …

Icts For Surveillance And Suppression: The Case Of The Indian Emergency 1975-1977, Ramesh Subramanian

Journal of International Technology and Information Management

Information and Communications technologies (ICT) pervade society. The Internet, wireless communication, and social media are ubiquitous in and indispensable in society today. As they continue to grow and mushroom, there are new and increased calls from various segments of the society such as technologists, activists, sociologists, and legal experts, who issue warnings on the more nefarious and undesirable uses of ICTs, especially by governments. In fact, government control and surveillance using ICTs is not a new phenomenon. By looking at history, we are able to see several instances when ICTs have been used by governments to control, surveil, and infringe …

Collective Impact In Rural Places, Sarah Zuckerman

Department of Educational Administration: Faculty Publications

Complex social problems such as teen pregnancy, youth suicide, student achievement, and foster care placement result from the interplay of problems in both the public and private sectors. Isolated approaches by single organizations in individual sectors, in general, have failed to “move the needle” on many of these problems. Such “wicked” problems are defined by complexity, interrelatedness, unpredictability, open-ended, intractable, and often subjected to competing values (Head & Alford, 2015). As such, wicked problems do not respond to technical, readymade solutions. Instead, they require adaptive and iterative approaches to learning about the causes of complex challenges, generating solutions, measuring the …

Intervention Of Climate-Smart Practices In Wheat Under Rice-Wheat Cropping System In Nepal, Janma Jaya Gairhe, Mandeep Adhikari, Deepak Ghimire, Arun Khatri-Chhetri, Dinesh Panday

Department of Agronomy and Horticulture: Faculty Publications

Besides a proper agronomic management followed by Nepalese farmers, wheat (Triticum aestivum L.) production has been severely affected by changing climate. There are many interventions, including climate-smart practices, to cope with this situation and possibly enhance crop and soil productivity. Field experiments were set up in a randomized complete block design with six treatments (TRT) with four replications in three locations (LOC) during wheat-growing seasons in Nepal from 2014 to 2016. Treatments included (i) Controlled Practice (CP), (ii) Improved Low (IL), (iii) Improved High (IH), (iv) Climate Smart Agriculture Low (CSAL), (v) Climate Smart Agriculture Medium (CSAM), and (vi) …

The late Quaternary of North America was marked by prominent ecological changes, including the end-Pleistocene megafaunal extinction, the spread of human settlements and the rise of agriculture. Here we examine the mechanistic reasons for temporal changes in mammal species association and body size during this time period. Building upon the co-occurrence results from Lyons et al. (2016) – wherein each species pair was classified as spatially aggregated, segregated or random – we examined body mass differences (BMD) between each species pair for each association type and time period (Late Pleistocene: 40 000 ¹⁴C–11 700 ¹⁴C ybp, Holocene: 11 …

School of Biological Sciences: Faculty Publications

As practitioners of a historical science, paleontologists and geoscientists are well versed in the idea that the ability to understand and to anticipate the future relies upon our collective knowledge of the past. Despite this understanding, the fundamental role that the history of paleontology and the geosciences plays in shaping the structure and culture of our disciplines is seldom recognized and therefore not acted upon sufficiently. Here, we present a brief review of the history of paleontology and geology in Western countries, with a particular focus on North America since the 1800s. Western paleontology and geology are intertwined with systematic …

Hydrologic model intercomparison studies help to evaluate the agility of models to simulate variables such as streamflow, evaporation, and soil moisture. This study is the third in a sequence of the Great Lakes Runoff Intercomparison Projects. The densely populated Lake Erie watershed studied here is an important international lake that has experienced recent flooding and shoreline erosion alongside excessive nutrient loads that have contributed to lake eutrophication. Understanding the sources and pathways of flows is critical to solve the complex issues facing this watershed. Seventeen hydrologic and land-surface models of different complexity are set up over this domain using the …

Environmental Correlates Of Genetic Variation In The Invasive European Starling In North America, Natalie R. Hofmeister, Scott J. Werner, Irby J. Lovette

United States Department of Agriculture Wildlife Services: Staff Publications

Populations of invasive species that colonize and spread in novel environments may differentiate both through demographic processes and local selection. European starlings (Sturnus vulgaris) were introduced to New York in 1890 and subsequently spread throughout North America, becoming one of the most widespread and numerous bird species on the continent. Genome-wide comparisons across starling individuals and populations can identify demographic and/or selective factors that facilitated this rapid and successful expansion. We investigated patterns of genomic diversity and differentiation using reduced-representation genome sequencing of 17 winter-season sampling sites. Consistent with this species' high dispersal rate and rapid expansion history, …

Estimation Of Wildlife Damage From Federal Crop Insurance Data, Sophie Mckee, Stephanie A. Shwiff, Aaron M. Anderson

United States Department of Agriculture Wildlife Services: Staff Publications

BACKGROUND: Wildlife damage to crops is a persistent and costly problem for many farmers in the USA. Most existing estimates of crop damage have relied on direct assessment methods such as field studies conducted by trained biologists or surveys distributed to farmers. In this paper, we describe a new method of estimating wildlife damage that exploits federal crop insurance data. We focused our study on four crops: corn, soybean, wheat, and cotton, chosen because of their economic importance and their vulnerability to wildlife damage.

RESULTS: We determined crop-raiding hot spots across the USA over the 2015–2019 period and identified the …

Anthraquinone Repellent Seed Treatment On Corn Reduces Feeding By Wild Pigs, Nathan P. Snow, Joseph M. Halseth, Scott J. Werner, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Wild pigs (Sus scrofa) are a destructive invasive species that cause extensive damage to agriculture throughout many regions of the world. In particular wild pigs damage corn more than any other crop, and most of that damage occurs immediately after planting when wild pigs excavate and consume planted seeds. We evaluated whether anthraquinone (AQ), a repellent, could be useful for protecting seed corn from consumption by wild pigs. Specifically, we conducted cafeteria-style tests at 16 bait sites for 6 nights using concentrations of: untreated, 0.5, 1.5, and 3.0% AQ by weight sprayed on whole-kernel corn in AL and …

The Marine Terraces Of Santa Cruz Island, California: Implications For Glacial Isostatic Adjustment Models Of Last-Interglacial Sea-Level History, Daniel R. Muhs, R. Randall Schumann, Lindsey T. Groves, Kathleen R. Simmons, Christopher R. Florian

United States Geological Survey: Staff Publications

Glacial isostatic adjustment (GIA) models hypothesize that along coastal California, last interglacial (LIG, broadly from ~130 to ~115 ka) sea level could have been as high as +11 m to +13 m, relative to present, substantially higher than the commonly estimated elevation of +6 m. Areas with low uplift rates can test whether such models are valid. Marine terraces on Santa Cruz Island have previously been reported to occur at low (<10 m) elevations, but ages of many such localities are not known. Using lidar imagery as a base, marine terraces on Santa Cruz Island were newly mapped, elevations were measured, fossils were collected for U-series dating (corals), strontium isotope compositions and amino acid geochronology (mollusks), and paleozoogeography (all taxa). Sr isotope compositions of mollusks from the highest of three marine terraces give ages of ~2.5 Ma to 1.9 Ma, along with Pliocene ages, fromshells interpreted to be reworked. U-series ages of corals fromthewestern part of the island indicate that low-elevation terraces north of the Santa Cruz Island fault correlate to the LIG. Where corals are lacking, amino acid ratios and faunal aspects support terrace correlation to the LIG high stand of sea. Elevations of most terrace localities north of the east-west trending Santa Cruz Island fault, in both thewestern and eastern parts of the island, range from5.75mto 8mabove sea level, well belowthe modeled paleo-sealevel range. Subsidence is ruled out as a mechanism for explaining the lower-than-modeled elevations, because higher-elevation terraces are present alongmuch of the Santa Cruz Island coast north of the fault, indicating longterm tectonic uplift. The low elevations of the LIG terrace fragments are, however, consistent with a low rate of uplift derived from the higher, ~2.5–1.9 Ma terrace. A number of other localities on the Pacific Coast, also dated to the LIG, have marine terrace elevations below the modeled level. GIA models may have overestimated last interglacial sea level by a substantial amount and need to be revised if used for forecasts for future sea-level rise.

Kings, Lords And Courts In Anglo-Norman England, Robert Hirshon

Articles

This is an important book, filling a significant gap in scholarship on late Anglo-Saxon and Anglo-Norman law, lordship, and administration. Its primary focus is on the hundred court and its relationship to lords’ local courts. Nicholas Karn argues (204) that, following the creation of shires and hundreds across England in the tenth century, by the middle of the eleventh “the unitary model of the hundred was starting to break down, and decay accelerated and became general into the twelfth century.” Lords either “claimed whole hundreds themselves, or they created lesser units which were originally subsets of hundreds and which were …

Theses and Dissertations (Comprehensive)

Northern Canada has struggled with various systemic challenges based on Eurocentric ideologies, policies, and practices. A major challenge Indigenous communities face North of the 60^th parallel is their food security and sovereignty. Inuit, First Nation and Métis populations across the North experience 5 to 6 times higher levels of food insecurity compared to the National average (Food Secure Canada, 2020). These communities face concentrated levels of food system issues, which connect to other factors, such as, health and wellness, the supply chain of market foods, governance, a shift away from traditional foods, and the impacts of climate change.

DEVELOPING POPULATION CONTROL STRATEGIES FOR WILD BOAR MANAGEMENT IN CANADA

Amanda Wong Advisor: Scott Slocombe

Wilfrid Laurier University 2020

Canada’s landscape faces major threats from the growing wild boar (Sus scrofa) population, whose current presence predominantly threatens the Prairie provinces. Globally it has become apparent that wild boars are robust animals with high reproductive rates and destructive behaviours in both their native and non-native ranges. This paper analyzes wild boar management strategies that have been conducted around the world to identify the most effective tools, and those that were unsuccessful. The wild boars in Canada are hybridized …

Characterization Of Micronutrient Dependent Growth By Several Temperate Freshwater Phytoplankton, Purnank Shah

Theses and Dissertations (Comprehensive)

Harmful algal blooms (HABs) are a growing problem in many freshwater waterbodies in Canada and around the world. HABs have wide-ranging impacts to ecosystems and economies. Since the 1970s, the primary focus of policies with respect to curbing HABs has been to lowering the inputs of P into waters. However, reports of HABs continue to increase even with all these P-removing policies in place. Some jurisdictions have chosen to focus on N-removal instead or in conjunction with P-removal to help with HABs. However, because some cyanobacteria have the ability to fix atmospheric N₂,N-removal might only lead to the …

Debilitating Publics: Reading Canlit's Investigations Into Psycho-Affective Pain And Social Change, Rebekah Ludolph

Theses and Dissertations (Comprehensive)

The reception studies that comprise this dissertation take up contemporary depictions of psycho-affective pain from the field of Canadian literature that are embraced by prominent literary publics as an act of social responsibility. Each study contextualizes the publics that review these texts within the ongoing use of literary culture to justify the settler state’s land claim, nationally reparative reading practices, and trends in the therapeutic use of literature. Tracing the affective reactions documented within each text’s reception, this study finds that narratives that fail to locate the nation as a reparative project are susceptible to interpretive practices that pathologize, rather …
