Population Structure And Phenotypic Variation Of Sclerotinia Sclerotiorum From Dry Bean (Phaseolus Vulgaris) In The United States, Zhian N. Kamvar, Bimal Sajeewa Amaradasa, Rachana Jhala, Serena Mccoy, James R. Steadman, Sydney Everhart

Department of Plant Pathology: Faculty Publications

The ascomycete pathogen Sclerotinia sclerotiorum is a necrotrophic pathogen on over 400 known host plants, and is the causal agent of white mold on dry bean. Currently, there are no known cultivars of dry bean with complete resistance to white mold. For more than 20 years, bean breeders have been using white mold screening nurseries (wmn) with natural populations of S. sclerotiorum to screen new cultivars for resistance. It is thus important to know if the genetic diversity in populations of S. sclerotiorum within these nurseries (a) reflect the genetic diversity of the populations in the surrounding region and (b) …

Dissecting The Genetic Basis Of Local Adaptation In Soybean, Nonoy B. Bandillo, Justin E. Anderson, Michael B. Kantar, Robert M. Stupar, James E. Specht, George L. Graef, Aaron J. Lorenz

Department of Agronomy and Horticulture: Faculty Publications

Soybean (Glycine max) is the most widely grown oilseed in the world and is an important source of protein for both humans and livestock. Soybean is widely adapted to both temperate and tropical regions, but a changing climate demands a better understanding of adaptation to specific environmental conditions. Here, we explore genetic variation in a collection of 3,012 georeferenced, locally adapted landraces from a broad geographical range to help elucidate the genetic basis of local adaptation. We used geographic origin, environmental data and dense genome-wide SNP data to perform an environmental association analysis and discover loci displaying steep …

Rooting For Food Security In Sub-Saharan Africa, Nicolas Guilpart, Patricio Grassini, Justin Van Wart, Haishun Yang, Martin K. Van Ittersum, Lenny G.J. Van Bussel, Joost Wolf, Lieven Claessens, Johan G.B. Leenaars, Kenneth G. Cassman

Department of Agronomy and Horticulture: Faculty Publications

There is a persistent narrative about the potential of Sub-Saharan Africa (SSA) to be a ‘grain breadbasket’ because of large gaps between current low yields and yield potential with good management, and vast land resources with adequate rainfall. However, rigorous evaluation of the extent to which soils can support high, stable yields has been limited by lack of data on rootable soil depth of sufficient quality and spatial resolution. Here we use location-specific climate data, a robust spatial upscaling approach, and crop simulation to assess sensitivity of rainfed maize yields to root-zone water holding capacity. We find that SSA could …

Lettuce Learn: Student Reflections On Building And Sustaining A Community Donation Garden, Hannah Dankbar, Emily K. Zimmerman, Carrie Chennault, Andrea D. Basche, Jacqueline Ann Nester, Maritza Pierre, Gabrielle Roesch-Mcnally

Department of Agronomy and Horticulture: Faculty Publications

This article emerged from conversations that we and fellow graduate students have had in building a community donation garden. We created the garden with a vision of enacting food justice in our community, but over the past four years we have experienced complexities with our vision. In this article, we share the complexities with which we have wrestled, how we have encouraged thoughtful dialogue among fellow scholars about these shortcomings and the intricate workings of the agrifood system, and the lessons we have learned through these experiences as early-career scholar-activists. This article represents our collective and individual voices as graduate …

Glaciation As A Migratory Switch, Robert M. Zink, Aubrey S. Gardner

School of Biological Sciences: Faculty Publications

Migratory behavior in birds is evolutionarily plastic, but it is unclear how this behavior responded during glacial cycles. One view is that at glacial maxima, species simply shifted their breeding ranges south of glacial ice and remained migratory. To test this hypothesis, we constructed ecological niche models for breeding and wintering ranges of 56 species, finding that 70% of currently long-distance North American migrant species likely lacked suitable breeding habitat in North America at the Last Glacial Maximum (LGM), and we hypothesized that they reverted to the ancestral state of being tropical sedentary residents. A smaller percentage of short-distance migrants …

Student Buy-In Toward Formative Assessments: The Influence Of Student Factors And Importance For Course Success, Kathleen R. Brazeal, Brian A. Couch

School of Biological Sciences: Faculty Publications

Formative assessment (FA) techniques, such as pre-class assignments, in-class activities, and post-class homework, have been shown to improve student learning. While many students find these techniques beneficial, some students may not understand how they support learning or may resist their implementation. Improving our understanding of FA buy-in has important implications, since buy-in can potentially affect whether students fully engage with and learn from FAs. We investigated FAs in 12 undergraduate biology courses to understand which student characteristics influenced buy-in toward FAs and whether FA buy-in predicted course success. We administered a mid-semester survey that probed student perceptions toward several different …

Evaluation Of Valiantzas’ Simplified Forms Of The Fao-56 Penman-Monteith Reference Evapotranspiration Model In A Humid Climate, Koffi Djaman, Daran Rudnick, Valere C. Mel, Denis Mutiibwa, Lamine Diop, Mamadou Sall, Isa Kabenge, Ansoumana Bodian, Hossein Tabari, Suat Irmak

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The unavailability of some meteorological variables, especially solar radiation and wind speed, is the main constraint for reference evapotranspiration (ETo) estimation using the standard United Nations Food and Agriculture Organization (FAO) Penman–Monteith (FAO-PM) equation in most developing countries. The application of ETo methods with fewer input requirements is necessary under limited climatic data conditions. The FAO-PM method under limited data conditions and nine of Valiantzas’ equations were evaluated for daily ETo estimation in a humid climate in Uganda. The FAO-PM method with missing relative humidity data performed very well across Uganda, whereas using the long-term local wind speed average values …

Incorporating Sociocultural Phenomena Into Ecosystem-Service Valuation: The Importance Of Critical Pluralism, Carena J. Van Riper, Amanda J. Landon, Sarah Kidd, Patrick Bitterman, Lee A. Fitzgerald, Elise F. Granek, Sonia Ibarra, David M. Iwaniec, Christopher M. Raymond, David Toledo

Geography Program: Faculty Publications

Ecosystem-services scholarship has largely focused on monetary valuation and the material contributions of ecosystems to human well-being. Increasingly, research is calling for a deeper understanding of how less tangible, nonmaterial values shape management and stakeholder decisions. We propose a framework that characterizes a suite of sociocultural phenomena rooted in key social science disciplines that are currently underrepresented in the ecosystem-services literature. The results from three example studies are presented to demonstrate how the tenets of this conceptual model can be applied in practice. We consider the findings from these studies in light of three priorities for future research: (1) complexities …

Professional And Personal Social Networking And Enhancement Of Social Capital In Young Adults, Maria Malu H. Roldan, Janejira Sutanonpaiboon, Richard Burkhard

Journal of International Technology and Information Management

PROFESSIONAL AND PERSONAL SOCIAL NETWORKING AND ENHANCEMENT OF SOCIAL CAPITAL IN YOUNG ADULTS

ABSTRACT

This study compares the use of personal and professional social networking sites by young adults for social capital enhancing activities. The research is based on a survey of college-age adults (n=292) who were asked about their use of two social networking sites of contrasting architectures: the more interactive, social/personal\-oriented site Facebook, and the relatively less interactive, professional/business-oriented site LinkedIn. Data were analyzed to determine the relationships among demographic and technology experience factors, and respondents’ use of these sites for social capital enhancing activities. Findings suggest that …

Biotic Interchange Has Structured Western Hemisphere Mammal Communities, Danielle Fraser, S. Kathleen Lyons

School of Biological Sciences: Faculty Publications

Aim.— Many hypotheses posit that species-rich tropical communities are dominated by speciesspecies interactions, apparent as competitive exclusion or character displacement, whereas species-poor temperate communities are dominated by species-environment interactions. Recent studies demonstrate a strong influence of macroevolutionary and biogeographic factors. We simultaneously test for the effects of species interactions, climate, and biotic interchange on Western Hemisphere mammal communities using a phylogenetic and functional diversity approach.

Location.— Western Hemisphere.

Time period.— Modern

Major taxa studied.— Mammalia

Methods.— Using Western Hemisphere mammal distributional and body mass data, we calculate body mass dispersion, phylogenetic diversity (Net Relatedness Index), and assemblage-averaged rates of co-occurrence …

Palynological Investigation Of Mummified Human Remains, Karl Reinhard, Marina Milanello Do Amaral, Nicole Wall

Karl Reinhard Publications

Pollen analysis was applied to a mummified homicide victim in Nebraska, U.S.A., to determine the location of death. A control sample showed the normal ambient pollen in the garage crime scene. Ambient windborne types, common in the air of the region, dominated the control. Internal samples were analyzed from the sacrum, intestine, and diaphragm. Microfossils were recovered from the rehydrated intestine lumen. The intestinal sample was dominated by Brassica (broccoli). The sacrum sample was high in dietary types but with a showing of ambient types. The pollen from the diaphragm was dominated by ambient pollen similar to the control samples. …

Degradation Of Crude 4‑Mchm (4-Methylcyclohexanemethanol) In Sediments From Elk River, West Virginia, Isabelle M. Cozzarelli, Denise M. Akob, Mary Jo Baedecker, Tracey Spencer, Jeanne Jaeschke, Darren S. Dunlap, Adam C. Mumford, Amisha T, Poret-Peterson, Douglas B. Chambers

United States Geological Survey: Staff Publications

In January 2014, approximately 37 800 L of crude 4-methylcyclohexanemethanol (crude MCHM) spilled into the Elk River, West Virginia. To understand the long-term fate of 4-MCHM, we conducted experiments under environmentally relevant conditions to assess the potential for the 2 primary compounds in crude MCHM (1) to undergo biodegradation and (2) for sediments to serve as a long-term source of 4-MCHM. We developed a solid phase microextraction (SPME) method to quantify the cis- and transisomers of 4-MCHM. Autoclaved Elk River sediment slurries sorbed 17.5% of cis-4-MCHM and 31% of trans-4-MCHM from water during the 2-week experiment. …

Panmixia And Limited Interspecific Introgression In Coyotes (Canis Latrans) From West Virginia And Virginia, Usa, Justin H. Bohling, Lauren L. Mastro, Jennifer R. Adams, Eric M. Gese, Sheldon F. Owen, Lisette P. Waits

United States Department of Agriculture Wildlife Services: Staff Publications

The expansion of coyotes (Canis latrans) into the eastern United States has had major consequences for ecological communities and wildlife managers. Despite this, there has been little investigation of the genetics of coyotes across much of this region, especially outside of the northeast. Understanding patterns of genetic structure and interspecific introgression would provide insights into the colonization history of the species, its response to the modern environment, and interactions with other canids. We examined the genetic characteristics of 121 coyotes from the mid-Atlantic states of West Virginia and Virginia by genotyping 17 polymorphic nuclear DNA microsatellite loci. These …

Attractants For Wild Pigs: Current Use, Availability, Needs, And Future Potential, Michael J. Lavelle, Nathan P. Snow, Justin W. Fischer, Joe M. Halseth, Eric H. Vannatta, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Populations of wild pigs (Sus scrofa) are burgeoning around the globe, and they are currently the target of extensive research and management efforts.Wild pigs are a highly successful invasive species that cause extensive damage to agriculture and native plant and animal communities. Lethal control is the most common management strategy used to reduce wild pig populations and their damage, and many lethal strategies rely on luring wild pigs to a specific location. Most commonly, a food commodity such as corn or maize (Zea mays) is used for attracting wild pigs to a site, but baiting with …

Influence Of Precipitation And Crop Germination On Resource Selection By Mule Deer (Odocoileus Hemionus) In Southwest Colorado, Emily M. Carrollo, Heather E. Johnson, Justin W. Fischer, Matthew Hammond, Patricia D. Dorsey, Charles Anderson, Kurt C. Vercauteren, W. David Walter

United States Department of Agriculture Wildlife Services: Staff Publications

Mule deer (Odocoileus hemionus) populations in the western United States provide many benefits to local economies but can also cause considerable damage to agriculture, particularly damage to lucrative crops. Limited information exists to understand resource selection of mule deer in response to annual variation in crop rotation and climatic conditions. We tested the hypothesis that mule deer select certain crops, and in particular sunflower, based on annual climatic variability. Our objective was to use movements, estimates of home range, and resource selection analysis to identify resources selected by mule deer. We used annually-derived crop-specific datasets along with Global …

Key Differences Between Lakes And Reservoirs Modify Climate Signals: A Case For A New Conceptual Model, Nicole M. Hayes, Bridget R. Deemer, Jessica R. Corman, N. Roxanna Razavi, Kristin E. Strock

United States Geological Survey: Staff Publications

Lakes and reservoirs are recognized as important sentinels of climate change, integrating catchment and atmospheric climate change drivers. Climate change conceptual models generally consider lakes and reservoirs together despite the possibility that these systems respond differently to climate-related drivers. Here, we synthesize differences between lake and reservoir characteristics that are likely important for predicting waterbody response to climate change. To better articulate these differences, we revised the energy mass flux framework, a conceptual model for the effects of climate change on lentic ecosystems, to explicitly consider the differential responses of lake versus reservoir ecosystems. The model predicts that catchment and …

Taking The First Bite: Who Should Tax Apple's $187 Billion In Ireland, Reuven S. Avi-Yonah, University Of Michigan Law School

Articles

On December 19, 2016, the European Commission (hereinafter “Commission”) published its final decision in the Apple State aid case. The Commission concluded that two tax rulings granted in 1991 and 2007 on the allocation of profits to the Irish branches of Apple Sales International (“ASI”) and Apple Operations Europe (“AOE”) amounted to illegal state aid, and ordered Ireland to immediately recover this aid from Apple. The key issue in the Apple decision is where Apple’s foreign income ($187 billion, as of 2016) should be regarded as being generated. In the authors’ opinion, there is almost no basis for any argument …

Numerical Investigation Of The Arctic Ice–Ocean Boundary Layer And Implications For Air–Sea Gas Fluxes, Arash Bigdeli, Brice Loose, An T. Nguyen, Sylvia T. Cole

Graduate School of Oceanography Faculty Publications

In ice-covered regions it is challenging to determine constituent budgets – for heat and momentum, but also for biologically and climatically active gases like carbon dioxide and methane. The harsh environment and relative data scarcity make it difficult to characterize even the physical properties of the ocean surface. Here, we sought to evaluate if numerical model output helps us to better estimate the physical forcing that drives the air–sea gas exchange rate (k) in sea ice zones. We used the budget of radioactive ²²²Rn in the mixed layer to illustrate the effect that sea ice forcing has …

Graduate School of Oceanography Faculty Publications

Phytoplankton are composed of diverse taxonomical groups, which are manifested as distinct morphology, size, and pigment composition. These characteristics, modulated by their physiological state, impact their light absorption and scattering, allowing them to be detected with ocean color satellite radiometry. There is a growing volume of literature describing satellite algorithms to retrieve information on phytoplankton composition in the ocean. This synthesis provides a review of current methods and a simplified comparison of approaches. The aim is to provide an easily comprehensible resource for non-algorithm developers, who desire to use these products, thereby raising the level of awareness and use of …

Exclusion From Rights Through Extra-Territoriality At Home: The Case Of Paris Roissy-Charles De Gaulle Airport's Waiting Zone, Pauline Gj Maillet

Theses and Dissertations (Comprehensive)

In this dissertation I argue that, since the 1980s, French airports have been designed to exclude people from legal, human and refugee rights. The particular space where this happens has been successively called “international zone”, “transit zone” and “waiting zone” and its scope has been significantly extended overtime. I contend that French authorities have used the concept of extra-territoriality in concert with the material design of the airport to sustain exclusion. While this research focuses on France, findings bear relevance to the global governance of migrants and refugees. The French case epitomizes how states creatively use the law (or absence …

Impact Of Linear Disturbances On A Discontinuous Permafrost Peatland Environment, Michael Braverman

Theses and Dissertations (Comprehensive)

Permafrost is ground that remains at or below 0°C for at least two consecutive years (PIWP, 2012). In the continuous permafrost zone its thickness may exceed 300 m, in lower latitudes, permafrost thickness is progressively decreasing, its occurrence becomes discontinuous and eventually sporadic (PIWP, 2012). At the southern fringe of permafrost in northwestern Canada, just about few meters. In subarctic peatlands permafrost is one of the main elements governing the hydrological processes. Being very thin and with temperature just fractions of the degree below 0^oC, it is very vulnerable to any changes in soil temperature and water content. …

With a particular focus on the creation and subsequent activities of the Defence Research Board (DRB), Canada’s first peacetime military science organization, the history covered here crosses political, social, and environmental themes pertinent to a detailed analysis of defence-related government activity in the Canadian North. Three contextual chapters on the history of federal defence research in Canada provide the foundation for a close study of defence research projects pursued and supported by the Canadian government. The dissertation …

Developing A Hydrological Monitoring Program For Ponds In Wapusk National Park, Manitoba, Using Water Isotope Tracers, Stephanie Roy

Theses and Dissertations (Comprehensive)

Northern lake-rich landscapes are vulnerable to increases in surface air temperatures and are changing in dynamic ways. Current meteorological records indicate that some of the greatest warming in the past century has occurred in the Hudson Bay Lowlands (HBL). As the HBL is an extensive wetland consisting of hundreds of thousands of shallow lakes and ponds, it is difficult to anticipate the long-term implications that climate change will have on pond water balance. To develop and implement long-term monitoring of hydrological conditions, sampling of pond water isotope composition has occurred during the past six years in Wapusk National Park (WNP), …

Permafrost Thaw Induced Changes To Runoff Generation And Hydrologic Connectivity In Low-Relief, Discontinuous Permafrost Terrains, Ryan Connon

Theses and Dissertations (Comprehensive)

Recent climate warming in northwestern Canada is occurring at an unprecedented rate in recorded history and has resulted in the widespread thaw of permafrost. Where present, permafrost exerts a significant control on local hydrology, and disappearance of permafrost threatens to change the hydrology of northern basins. In the peatlands that characterise the southern distribution of permafrost in low relief terrain, permafrost takes the form of forested peat plateaus and is interspersed by permafrost-free wetlands (i.e. channel fens and flat bogs). Previous field studies have found that channel fens serve as the drainage network and route water to the basin …

Marine Protected Areas In Colombia: Re-Connecting Social, Ecological, And Policy Aspects Through A Governance Perspective, Luisa Ramirez

Theses and Dissertations (Comprehensive)

The purpose of this doctoral research is to examine opportunities and constraints for integrating key aspects of governance into marine conservation strategies and for shifting top-down approaches toward collaborative and integrative forms of governance that enhance conservation and social outcomes in marine protected areas (MPAs).

Although there is evidence that demonstrates that MPAs are an effective tool for marine conservation, shortcomings in addressing ecological characteristics and particularly in addressing social factors in the design and planning of MPAs often constrain achieving conservation and sustainability goals. These shortcomings are particularly acute in MPAs implemented through top-down governance approaches that overlook stakeholder …

The Making Of Astate In Waiting: The Lives Of Fatah Political Prisoners, 1967 To 1985, Rebecca Granato

Theses and Dissertations (Comprehensive)

A State in Waiting? The Lives of Fatah Political Prisoners, 1967-1985 looks at the evolution of a Fatah prisoner movement inside Israeli prisons intended for Palestinian political prisoners. An under-researched area in Palestinian studies, this project relies on a combination of oral sources and anonymous documents drafted by prisoners during their internment housed at the Abu Jihad Museum in Abu Dis, Palestine. The dissertation argues that beginning in the 1970s and lasting into the 1980s a kind of collectivity emerged and came to define prisoner interactions and their day-to-day activities. Prison, and later system-wide hunger strikes are addressed in an …
