Giant Ragweed (Ambrosia Trifida L.) Biology, Competition, And Control In Cotton (Gossypium Hirsutum L.), Kelly Anna Barnett

Doctoral Dissertations

The objectives of this research were to evaluate control options and investigate the biology and competitiveness of glyphosate-resistant (GR) giant ragweed in cotton. Our results determined that glufosinate followed by glufosinate, glufosinate plus pyrithiobac, and glufosinate plus fluometuron at 0.56 or 1.12 kg ai ha^-1 resulted in the highest level of visual control and the highest yield. However, glufosinate followed by glufosinate was the only treatment that resulted in the highest yield and > 90% control of GR giant ragweed.

The development of glufosinate-tolerant, 2,4-D tolerant, and dicamba-tolerant crops may provide growers with new opportunities for difficult-to-control weeds such as …

Winter Microhabitat Foraging Preferences Of Sympatric Boreal And Black-Capped Chickadees In Michigan's Upper Peninsula, Alec R. Lindsay Ph. D., Zach G. Gayk

Faculty Works

We examined differences in microhab- itat use between Boreal (Poecile hudsonicus) and Black- capped chickadees (P. atricapillus) where they co-occur near Marquette, Michigan, USA. Twenty-four Boreal and 37 Black-capped chickadees were followed during 60 hrs of field observation. Boreal Chickadees foraged only in three conifer species, 76% of which were black spruce (Picea mariana), while Black-capped Chickadees foraged widely across six coniferous and three deciduous tree species. Analysis of foraging data categorized by zones within conifer trees indicated high niche overlap (0.676) between Boreal and Black-capped chickadees across all foraging zones. Individual comparisons on a zone-by-zone basis revealed a significant …

Life History Variation Of Common Terns In The Gulf Of Maine, Jeffery Bryant Kimmons

Graduate Theses and Dissertations

Life history is the inheritable rules that determine energy and time allocation towards different competing functions in the energy budget of an organism. Reproductive effort varies as organisms make reproductive decisions based on available energy. Factors influencing life histories are those that change energy and time budgets such as diet, competition, and environmental conditions.

Common tern (Sterna hirundo) life history phenotypes vary between islands in the Gulf of Maine. Common terns on offshore islands (>10km from mainland) and nearshore islands (5 to 10km from mainland) lay smaller clutches, hatching chicks with slower growth rates than common terns …

Intraspecific Density Dependence And A Guild Of Consumers Coexisting On One Resource, Mark A. Mcpeek

Dartmouth Scholarship

The importance of negative intraspecific density dependence to promoting species coexistence in a community is well accepted. However, such mechanisms are typically omitted from more explicit models of community dynamics. Here I analyze a variation of the Rosenzweig-MacArthur consumer–resource model that includes negative intraspecific density dependence for consumers to explore its effect on the coexistence of multiple consumers feeding on a single resource. This analysis demonstrates that a guild of multiple consumers can easily coexist on a single resource if each limits its own abundance to some degree, and stronger intraspecific density dependence permits a wider variety of consumers to …

Energy Development And Conservation Of Sympatric Wildlife : New Approaches To Meet Growing Challenges, William Dunn

Biology ETDs

Conflicts between energy development and conservation of sympatric wildlife are becoming more acute as demand for energy increases. Resolving these conflicts is complex-- solutions must address the role of location, scale, and connectivity in persistence of populations. In Chapter 1, I use the MaxEnt species distribution model and pertinent climate variables to predict the natural distribution of the Lesser Prairie Chicken (LPC) (Tympanuchus pallidicinctus), a prairie grouse adversely affected by habitat loss from energy development. Within the geographic range of LPC, precipitation was strongly associated with its distribution in the north, whereas temperature was strongly associated with its distribution in …

Competition And Innovation In Copyright And The Dmca, Herbert J. Hovenkamp

All Faculty Scholarship

This book of CASES AND MATERIALS ON INNOVATION AND COMPETITION POLICY is intended for educational use. The book is free for all to use subject to an open source license agreement. It differs from IP/antitrust casebooks in that it considers numerous sources of competition policy in addition to antitrust, including those that emanate from the intellectual property laws themselves, and also related issues such as the relationship between market structure and innovation, the competitive consequences of regulatory rules governing technology competition such as net neutrality and interconnection, misuse, the first sale doctrine, and the Digital Millennium Copyright Act (DMCA). Chapters …

Joint Modeling Of Spatial Variability And Within-Row Interplot Competition To Increase The Efficiency Of Plant Improvement, J. Stringer, Brian Cullis, R Thompson

Professor Brian Cullis

Trials in the early stages of selection are often subject to variation arising from spatial variability and interplot competition, which can seriously bias the assessment of varietal performance and reduce genetic progress. An approach to jointly model both sources of bias is presented. It models genotypic and residual competition and also global and extraneous spatial variation. Variety effects were considered random and residual maximum likelihood was used for parameter estimation. Competition at the residual level was examined using two special simultaneous autoregressive models. An equal-roots second-order autoregressive (EAR(2)) model is proposed for trials where competition is dominant. An equal-roots third-order …

We decided to be rivals, he and I. It was a casual decision, made over tea. Tea is a casual drink. You drink it to feel casual. And in our casual state we felt we could be rivals. “We should be rivals,” we said. “So we shall!” we announced.

Reaching For The Brass Ring: The U.S. News & World Report Rankings And Competition, Ronald Ehrenberg

Ronald G. Ehrenberg

[Excerpt] The behavior of academic institutions, including the extent to which they collaborate on academic and nonacademic matters, is shaped by many factors. This paper focuses on one of these factors, the U.S. News & World Report (USNWR) annual ranking of the nation’s colleges and universities as undergraduate institutions, exploring how this ranking exacerbates the competitiveness among American higher education institutions. After presenting some evidence on the importance of the USNWR rankings to both public and private institutions at all levels along the selectivity spectrum, I describe how the rankings actually are calculated, then discuss how academic institutions alter their …

Do Social Conditions Affect Capuchin Monkeys' (Cebus Apella) Choices In A Quantity Judgment Task?, Michael J. Beran, Bonnie M. Perdue, Audrey E. Parrish, Theodore A. Evans

Language Research Center

Beran et al. (2012) reported that capuchin monkeys closely matched the performance of humans in a quantity judgment test in which information was incomplete but a judgment still had to be made. In each test session, subjects first made quantity judgments between two known options. Then, they made choices where only one option was visible. Both humans and capuchin monkeys were guided by past outcomes, as they shifted from select- ing a known option to selecting an unknown option at the point at which the known option went from being more than the average rate of return to less than …

Conclusion: Markets, Strategies, And Institutions In Comparative Perspective, Kirsten S. Wever, Lowell Turner

Lowell Turner

[Excerpt If this had been another collection of country case studies, it would now be possible to map out the similarities and differences across the cases covered, possibly in a figure describing various IR-related issues by country. However, since this is a collection of different kinds of analyses with a variety of different focuses, the job of concluding this volume is not so simple. Nevertheless, in the very variety offered by the chapters in this volume, several themes emerge, most of which are at least implicitly, if not explicitly, clarified in the five substantive chapters. The chapters point up the …

Applications Barriers To Entry And Exclusive Vertical Contracts In Platform Markets, James Prieger, Wei-Min Hu

James E. Prieger

Our study extends the empirical literature on whether vertical restraints are anticompetitive. We focus on exclusive contracting in platform markets, which feature indirect network effects and thus are susceptible to applications barriers to entry. Exclusive contracts in vertical relationships between the platform provider and software supplier can heighten entry barriers. We test these theories in the home video game market. We find that indirect network effects from software on hardware demand are present, and that exclusivity takes market share from rivals, but only when most games are non-exclusive. The marginal exclusive game contributes virtually nothing to console demand. Thus, allowing …

The Broadband Digital Divide And The Nexus Of Race, Competition, And Quality, James Prieger, Wei-Min Hu

James E. Prieger

We examine the gap in broadband access to the Internet between minority groups and white households with geographically fine data on DSL subscription. In addition to income and demographics, we also examine quality of service and competition as components of the Digital Divide. The gaps in DSL demand for blacks and Hispanics do not disappear when income, education, and other demographic variables are accounted for. However, lack of competition is an important driver of the Digital Divide for blacks. Service quality is an important determinant of demand, and ignoring it masks the true size of the DSL gap for Hispanics.

Antitrust And The Costs Of Movement, Herbert J. Hovenkamp

All Faculty Scholarship

Antitrust is rightfully concerned about the structure of markets as well as the bargaining that occurs in them. As a result, the absolute cost of redeploying resources can be just as important as the transaction costs of arranging for their movement. This paper examines several broad themes in antitrust, considering the role of various assumptions about the costs of getting resources moved toward superior positions and the ability of the antitrust system to facilitate this movement. Part II very briefly examines structuralism as a theory underlying antitrust enforcement, particularly its assumptions about the difficulty and costs of moving resources. Harvard …

Is Competition Always Good?, Maurice Stucke

Scholarly Works

Competition is the backbone of U.S. economic policy. The U.S. Supreme Court observed, “The heart of our national economic policy long has been faith in the value of competition.” Competition advocacy is also thriving internationally. Promoting competition is broadly accepted as the best available tool for promoting consumer well-being. Competition officials, who regularly try to protect the public from anticompetitive special interest legislation, are justifiably jaded about complaints of excess competition. Although the economic crisis has prompted some policymakers to reconsider basic assumptions, the virtues of competition are not among them.

Nonetheless to effectively advocate competition, officials must understand when …

Competition In Information Technologies: Standards-Essential Patents, Non-Practicing Entities And Frand Bidding, Herbert J. Hovenkamp

All Faculty Scholarship

Standard Setting is omnipresent in networked information technologies. Virtually every cellular phone, computer, digital camera or similar device contains technologies governed by a collaboratively developed standard. If these technologies are to perform competitively, the processes by which standards are developed and implemented must be competitive. In this case attaining competitive results requires a mixture of antitrust and non-antitrust legal tools.

FRAND refers to a firm’s ex ante commitment to make its technology available at a “fair, reasonable and nondiscriminatory royalty.” The FRAND commitment results from bidding to have one’s own technology selected as a standard. Typically the FRAND commitment is …

Comparative Ecophysiology Of Grain Sorghum And Abutilon Theophrasti In Monoculture And In Mixture, Samba Traoré, John L. Lindquist, Stephen Mason, Alex Martin, D. A. Mortensen

John L. Lindquist

Selection of crop genotypes that are more competitive with weeds for light interception may improve crop yield stability in the presence of weeds. The effects of interference on ecophysiological characteristics of Abutilon theophrasti Medic. and three morphologically diverse grain sorghum hybrids was evaluated to determine the relative tolerance and suppressive ability of the three hybrids and specific traits that may contribute to those differences. A tall hybrid was more tolerant to A. theophrasti interference than two medium stature hybrids. Early leaf area growth of two medium-stature sorghum hybrids was reduced by A. theophrasti interference, whereas early growth of a tall …

Light-Saturated Co2 Assimilation Rates Of Corn And Velvetleaf In Response To Leaf Nitrogen And Development Stage, John L. Lindquist

John L. Lindquist

Single-leaf CO₂ assimilation rate under saturating light (C_A) varies as a function of leaf nitrogen content per unit leaf area (N_L). Measured C_A for many crop species also declines with developmental stage. Because these relationships may have strong implications for crop–weed competition, a field experiment was conducted to quantify corn and velvetleaf C_A as influenced by leaf N_L and stage of development. Crop and weed C_A were measured on the most recent fully expanded leaves of plants grown in four nitrogen (N) application treatments. Both corn and velvetleaf C_A increased …

Performance Of Weedsoft For Predicting Soybean Yield Loss, Shawn M. Hock, Stevan Z. Knezevic, Alex Martin, John L. Lindquist

John L. Lindquist

Decision support systems (DSSs) have been developed to assist producers and consultants with weed management decisions. WeedSOFT is a DSS currently used in several states in the northcentral region of the United States. Accurate estimates of crop yield loss due to weed interference are required for cost-effective weed management recommendations. WeedSOFT uses competitive indices (CIs) to predict crop yield loss under multiple weed species, weed densities, and relative times of weed emergence. Performance of several WeedSOFT versions to predict soybean yield loss from weed competition was evaluated using CI values in WeedSOFT version 9.0 compared to new CI values calculated …

Corn–Velvetleaf (Abutilon Theophrasti ) Interference Is Affected By Sublethal Doses Of Postemergence Herbicides, Brescia R. M. Terra, Alexander R. Martin, John L. Lindquist

John L. Lindquist

Injury to weeds from sublethal doses of POST herbicides may reduce the effect of weed interference on crop yield. Information on how herbicide dose influences weed mortality, growth, and seed production is needed to assess the potential benefit of applying reduced herbicide doses. Field experiments were conducted at Mead, NE, in 2001 and 2002 to quantify velvetleaf mortality, growth, and corn–velvetleaf interference in response to varying doses of three POST herbicides. Untreated velvetleaf at six densities (0, 1, 3, 6, 12, and 20 plants m-1 corn row) was grown in mixture with corn to establish a baseline corn–velvetleaf interference relationship. …

Regional Rarity: Consequences Of Dispersal Limitation And Strategies For Reintroduction, Steven James Kroiss

All Theses and Dissertations (ETDs)

Understanding factors that limit species distributions within restored habitats has been a longstanding goal of restoration ecology, particularly with respect to differences between rare and widespread species. Numerous mechanisms have been proposed to contribute to rarity, including species traits, propagule limitation, ecological requirements, and population level processes such as demographic and environmental stochasticity. Yet, our understanding of species rarity remains limited since few studies have examined how these factors act in concert. This dissertation examines how these mechanisms may interact to influence the distribution and population establishment of plant species in restored xeric glades in the Missouri Ozarks: USA). First, …

Race, Markets, And Hollywood's Perpetual Antitrust Dilemma, Hosea H. Harvey

Michigan Journal of Race and Law

This Article focuses on the oft-neglected intersection of racially skewed outcomes and anti-competitive markets. Through historical, contextual, and empirical analysis, the Article describes the state of Hollywood motion-picture distribution from its anticompetitive beginnings through the industry's role in creating an anti-competitive, racially divided market at the end of the last century. The Article's evidence suggests that race-based inefficiencies have plagued the film distribution process and such inefficiencies might likely be caused by the anti-competitive structure of the market itself, and not merely by overt or intentional racial-discrimination. After explaining why traditional anti-discrimination laws are ineffective remedies for such inefficiencies, the …

The Crisis In Legal Education: Dabbling In Disaster Planning, Kyle P. Mcentee, Patrick J. Lynch, Derek M. Tokaz

University of Michigan Journal of Law Reform

The legal education crisis has already struck for many recent law school graduates, signaling potential disaster for law schools already struggling with their own economic challenges. Law schools have high fixed costs caused by competition between schools, the unchecked expansion of federal loan programs, a widely exploited information asymmetry about graduate employment outcomes, and a lack of financial discipline masquerading as innovation. As a result, tuition is up, jobs are down, and skepticism of the value of a J.D. has never been higher. If these trends do not reverse course, droves of students will continue to graduate with debt that …

The Crisis Of The American Law School, Paul Campos

University of Michigan Journal of Law Reform

The economist Herbert Stein once remarked that if something cannot go on forever, it will stop. Over the past four decades, the cost of legal education in America has seemed to belie this aphorism: it has gone up relentlessly. Private law school tuition increased by a factor of four in real, inflation-adjusted terms between 1971 and 2011, while resident tuition at public law schools has nearly quadrupled in real terms over just the past two decades. Meanwhile, for more than thirty years, the percentage of the American economy devoted to legal services has been shrinking. In 1978 the legal sector …
