Epidemiology And Management Of Frogeye Leaf Spot Of Soybean: Damage Thresholds, Efficacy And Profitability Of Foliar Fungicides, Jhonatan Paulo Barro

Theses and Dissertations--Plant Pathology

Frogeye leaf spot (FLS), caused by Cercospora sojina, is an economically important disease of soybean in many parts of the world where soybean is grown, including the United States. A meta-analytic approach was used to summarize a data set of 66 uniform field research trials conducted to evaluate fungicide efficacy against FLS on soybean. The dataset spanned 10 years (2012 to 2021) of experiments conducted across eight states in the U.S., including Alabama, Arkansas, Illinois, Iowa, Kentucky, Louisiana, Mississippi and Tennessee. First, the relationship between FLS severity and soybean yield was investigated. A significant negative slope obtained through random …

The Negative Effects Of Cannabis On Memory Processes, Kiera Wingo

2022 Fall Honors Capstone Projects - Archive

The purpose of this review is to determine if there is a negative effect of cannabis on memory processes. Specifically, the negative effects of cannabis on short-term, working, and episodic memory were examined within acute or chronic users. Several formal databases and Google Scholar were used to find relevant literature, where key words provided search parameters and narrowed results. A final total of 29 relevant studies were used in the results. The resulting literature employed numerous study methods including N-back, Sternberg, verbal recall measures, and neuroimaging techniques. The results confirmed a negative relationship between cannabis and memory when participants were …

Comparing Prairie Management Methods’ Effects On Three Native Texan Grasses, Stephanie Howell

2022 Fall Honors Capstone Projects - Archive

The Texas Blackland Prairie habitat is under extreme threat. Currently, only 1% of the original prairie remains. Restoration efforts across the state have aimed to address these concerns. This research set out to test the efficacy of the methods used to restore prairies regarding three grasses. Big Bluestem, Andropogon gerardii, Little Bluestem, Schizachyrium scoparium, and Indiangrass, Sorghastrum nutans, were surveyed to establish their species abundance on two fields in North Texas. Based on their abundance and the history of each field, conclusions were drawn on the efficacy of the maintenance. Seeding was found to be inconsequential for A. gerardii and …

Factors Affecting The Sex Ratio Of White-Tailed Deer (Odocoileus Virginianus) Fetuses In Arkansas, Jorista Garrie, Ralph Meeker

Journal of the Arkansas Academy of Science

Health of the mother is known to affect the sex-ratio of the offspring in sexually dimorphic mammals. Both density-dependent and environmental factors (conditions at present, or seasonal conditions the year before) could impact the health of the mother. There are however two opposing hypotheses for whether a mother in good health should invest more in a strong son (that can father many offspring) or in a daughter (that can stay in the same area and use good resources). Fetuses from 1,208 female white-tailed deer (Odocoileus virginianus) were collected over a 10-year period (2002-2012), across 75 counties in Arkansas. …

Seasonal Testicular Histology And Acystic Lobular Spermatogenesis In The Western Lesser Siren, Siren Intermedia Nettingi (Caudata: Sirenidae), Stanley E. Trauth

Journal of the Arkansas Academy of Science

I investigated the seasonal testicular histology and acystic lobular spermatogenesis in the Western Lesser Siren, Siren intermedia nettingi, from periodic sampling of this salamander over a span of 21 yr (1994-2015) in northeastern Arkansas. My results include the following general findings: 1) the largest testicular lobules occurred primarily in January-February during spermiogenesis and spermatozoa maturation; 2) lobular regression and spermatogenic cell recrudescence were underway by late March; 3) proliferation of secondary spermatogonia in lobules was prominent in May; 4) transformation of secondary spermatogonia into primary spermatocytes occurred by mid-July, and these cells became larger in diameter through increased nuclear …

Distribution And Breeding Of The Black-Bellied Whistling-Duck (Dendrocygna Autumnalis) In Arkansas, With A Brief Chronology Of Distribution And Breeding In Southeastern United States, C. Renn Tumlison

Journal of the Arkansas Academy of Science

The Black-Bellied Whistling-Duck (Dendrocygna autumnalis) was a rare bird first reported from Arkansas in 1982, when it was seen in Hempstead Co. in southwestern Arkansas. Observations surged in parts of the state about 2005, then again about 2016, and the bird is now fairly common seasonally in many parts of the state. By use of online sources for citizen science, we elucidate the history of occurrence and present analysis of seasonal distribution of this bird in Arkansas. Individuals occur in Arkansas throughout the year, but observations are most common and widely distributed from March-September, after which most individuals …

Effects Of Clipping Of Flight Feathers On Resource Use In Gallus Gallus Domesticus, Renee Garant, Bret W. Tobalske, Neila Bensassi, Nienke Van Staaveren, Dan Tulpan, Tina Widowski, Donald R. Powers, Alexandra Harlander-Matauschek

Faculty Publications - Department of Biological & Molecular Science

Ground-dwelling species of birds, such as domestic chickens (Gallus gallus domesticus), experience difficulties sustaining flight due to high wing loading. This limited flight ability may be exacerbated by loss of flight feathers that is prevalent among egg-laying chickens. Despite this, chickens housed in aviary style systems need to use flight to access essential resources stacked in vertical tiers. To understand the impact of flight feather loss on chickens’ ability to access elevated resources, we clipped primary and secondary flight feathers for two hen strains (brown-feathered and white-feathered, n = 120), and recorded the time hens spent at elevated resources (feeders, …

Investigating The Role Corynebacterium Matruchotii Has Within Supragingival Plaque Spatial Organization And Its Response To Oral Streptococci And Saliva, Eric Ganeto Almeida

Open Access Dissertations

Human supragingival plaque (SUPP) is a polymicrobial biofilm on the tooth surface above the gumline, comprised of ordered structures with spatial associations between specific bacterial taxa. Recent microscopy and microbiome data have suggested that some plaque structures are scaffolded by the abundant filamentous bacterium Corynebacterium matruchotii decorated with Streptococcus species. These taxa are able to make a reproducible structure known as the ‘Hedgehog’ model in vivo where Streptococcus species tend to form 'corncob' like structures around the terminal ends of C. matruchotii. As these species colocalize in vivo, we hypothesize that they also interact biochemically with one another. …

Concept Maps For Middle School Computer Science Assessment, Gabriel De Pace

Open Access Dissertations

Concept Mapping has long been used in academic settings for various pur- poses but has been underutilized for assessment. Creating the concept map task and scoring the maps have been barriers to their widespread acceptance, but these difficulties are mitigated with automation and simple tools for the teacher to use. The aim of this work is to show that concept maps can be used effectively as computer science assessments in secondary schools. Ultimately, they can be used to measure student knowledge and to complement other forms of classroom assessments. We used the Code.org CS Discoveries Units 1-3 Curriculum taught in …

The Power Of Reciprocity: How The Confederated Salish & Kootenai Water Compact Illuminates A Path Toward Natural Resources Reconciliation, Michelle Bryan

Water Law Review

This article chronicles the negotiation and recent passage of the Confederated Salish & Kootenai Tribes Water Compact, which creates one of the most innovative water management regimes envisioned among sovereigns. The Compact's journey toward ratification is extraordinary, as the parties over the span of three decades worked to overcome historically entrenched racism and political opposition to craft a model that would provide enough water for all peoples and the fishery. Compounding the challenge, the Flathead Reservation itself contains vast swaths of checkerboard land held by non-Indians and a major federal irrigation project that has permanently altered the hydrograph of the …

Decapod Sentience: Broadening The Framework, Cecilia De Souza Valente

Animal Sentience

A framework for studying sentience in decapods is of great value, but how high a cost (in suffering) to each individual decapod (or any animal) is warranted for collecting scientific evidence of sentience? The lack of evidence for some of the target article’s proposed criteria surely results from the fact that research is focused mainly on biomedical studies, ecotoxicology, and commercial production, with decapod sentience and welfare seen as only a secondary research topic. I draw attention also to the possibility of a wider framework that includes all felt experiences, from suffering to pleasure.

Independence, Weight And Priority Of Evidence For Sentience, Elizabeth Irvine

Animal Sentience

This commentary maps out relationships of dependency between the criteria proposed in the target article (Crump et al. 2022), identifying the criteria that carry most of the weight of the evidence, and suggesting which criteria should have priority in research on sentience.

Sentience In Decapods: Difficulties To Surmount, Michael L. Woodruff

Animal Sentience

In the target article Crump et al. present 8 criteria to assess whether decapods experience pain. Four of these -- sensory integration, motivational trade-offs, flexible self-protection, and associative learning -- could be used to assess sentience in general. In this commentary I discuss difficulties with using these criteria to provide evidence of sentience in decapods, particularly if this evidence is to change public opinion and policies. These difficulties are lack of evidence, the potential to eventually explain the neurobiological basis of the behaviors chosen as criteria, thereby eliminating any explanatory work for sentience, and the reluctance to bring animals that …

Pain In Pleocyemata, But Not In Dendrobranchiata?, Gary Comstock

Animal Sentience

Crump et al.’s contribution to assessing whether decapods feel pain raises an important question: Is pain distributed unevenly across the order? The case for pain appears stronger in Pleocyemata than in Dendrobranchiata. Some studies report pain avoidance behaviors in Dendrobranchiata (Penaeidae) shrimp, but further studies are needed to determine whether the chemicals used are acting as analgesics to relieve pain, or as soporifics to reduce overall alertness. If the latter, the most farmed shrimp species may not require the same level of protection as crabs, crayfish, and lobsters.

Sentience As Part Of Emotional Lives, Frans B. M. De Waal

Animal Sentience

It is high time to explore the sentience of invertebrate animals, but this topic cannot be discussed without also exploring their emotional lives, including positive emotions. Sentience probably evolved to allow the regulation of emotions by endowing them with feelings.

How Much Of A Pain Would A Crustacean “Common Currency” Really Be?, Simon A. B. Brown

Animal Sentience

We should be suspicious of the idea that experiencing pain could enable animals to trade off different motivations in a common currency. It is not even clear that humans have a common motivational currency reflected in evaluative experience. Instead, pain may capture attention, inhibiting attention to competing motivations and needs, thereby making genuine trade-offs harder. Our criteria for pain in invertebrates should be part of a more subtle theory of the relationship between pain and decision-making.

Decapod Sentience: Promising Framework And Evidence, Jon Mallatt, Todd E. Feinberg Md

Animal Sentience

Strong points of the target article by Crump et al. are that it offers clear criteria for judging whether decapods are sentient, an effective semi-quantitative grading system for this purpose, and an astute, critical review of the literature. It concludes plausibly that major subgroups of decapods are sentient. A minor problem is that it includes classical, Pavlovian learning as a marker of sentience along with the more valid marker of complex (e.g., operant) learning. Another minor problem is that it does not distinguish results that are negative because of likely absence of sentience from results that are negative because they …

Extending The Null Hypothesis To Invertebrate Pain Sentience, Eva Kakrada, Michael Colombo

Animal Sentience

In 1985 Macphail proposed his Null Hypothesis that there were no qualitative differences in intelligence across vertebrate species. A recent review of the literature has found overwhelming support for his view. Studies also suggest that, with respect to cognition and the neural mechanisms that support it, the Null Hypothesis should be extended to invertebrates. We suggest, on the same premise, that the Null Hypothesis should be extended to pain sentience in invertebrates. Although few studies have been conducted, behavioural and neural evidence for pain sentience has been found in various representative invertebrate species.

Decapods As Food, Companions And Research Animals: Legal Impact Of Ascribing Sentience, Jonathan J. Cooper, Ambrose Tinarwo, Beth A. Ventura

Animal Sentience

This commentary provides an overview of the practical implications of attributing sentience to protect decapods as food, companion and research animals in the UK context. Recognising their capacity to suffer has implications for humane slaughter in farming and fishing sectors. It should also place a greater duty of care on owners of captive decapods, considering their needs and avoiding unnecessary suffering. The recognition of decapod sentience should also have an impact on their protection as research animals, although research with a potential to cause suffering may be needed to better understand decapods’ capacity to suffer.

A Framework For Evaluating Evidence Of Pain In Animals, Matilda Gibbons, Lars Chittka

Animal Sentience

Crump et al. define eight criteria indicating sentience in animals, with a focus on pain. Here, we point out the risk of false negative or false positive diagnoses of pain. Criteria of different levels of inclusivity are useful for using the precautionary principle in animal welfare considerations, and for more formal scientific evidence of pain. We suggest tightening the criteria -- from more general evidence of sentience to pain alone -- because crucial evidence for animal welfare decisions might otherwise be missed for animals subjected to invasive and injurious procedures.

Pros And Cons Of A Framework For Evaluating Potential Pain In Decapods, Robert W. Elwood

Animal Sentience

The rigorous framework for research into potential pain in decapods was successful in allowing legislators in the United Kingdom to evaluate a complex scientific issue. However, it might produce problems for research. I discuss doubts about the usefulness of the eight criteria. Some have yet to receive any investigation and others do not allow much inference about pain. In addition, some existing studies are not covered in the framework. Most worrying, however, is the potential for stifling future research of novel areas that are excluded from the framework.

Integrating Evolution Into The Study Of Animal Sentience, Walter Veit

Animal Sentience

Like many others, I see Crump et al. (2022) as a milestone for improving upon previous guidelines and for extending their framework to decapod crustaceans. Their proposal would benefit from a firm evolutionary foundation by adding the comparative measurement of life-history complexity as a ninth criterion for attributing sentience to nonhuman animals.

Animal Sentience Research: Synthesis And Proposals, Andrew Crump, Heather Browning, Alex Schnell, Charlotte Burn, Jonathan Birch

Animal Sentience

Most commentaries on our target article broadly support our approach to evaluating evidence of animal sentience. In this Response, we clarify the framework’s purpose and address criticisms of our criteria. A recurring theme is that a framework to synthesise current evidence of sentience is not the same as an agenda for future directions in animal sentience research. Although future directions are valuable, our framework aims to evaluate existing evidence and inform animal welfare legislation.

In Memoriam Professor Emeritus Egon Guttmon, Claudio Grossman, Walter A. Effross, David Snyder

Scholarly Articles in Law Reviews & Journals

When I think about Egon, the first thing that comes to mind are the memories when we met in 1982 at the Washington College of Law (WCL), where he was working as a full-time faculty member. I was coming at that time from my sabbatical in the Netherlands and as a Fulbright Scholar. From the beginning, Egon sought to provide me with a welcoming environment. He approached me, finding shared backgrounds and interests, which is always greatly appreciated, particularly when you are in a new institution. Egon noted that we both had an intellectual interest in international law. In addition …

For Grand Juries, Roger Fairfax

Scholarly Articles in Law Reviews & Journals

In his provocative essay, Against Prosecutors, Professor Bennett Capers contributed to a now-robust conversation that was on the fringes just a decade ago. Although it remains to be seen whether the pendulum will swing away from the engagement with abolitionist theory that intensified in the wake of the May 2020 murder of George Floyd, a number of serious thinkers have staked out ground questioning the dogma that organs of the criminal legal system are inevitable.

Refusing to be burdened by conventions of the past, Capers trains his sights on another criminal justice institution—public prosecution. Although prosecutors long have been criticized …
