The Effect Of Phosphorus Fertilization On Botanical Composition And Production In Temperate Pastures In Argentina, E. J. Jacobo, A. M. Rodríguez, M. F. Garbulsky, P. Scardoni, V. A. Deregibus

IGC Proceedings (1977-2023)

The objective of this paper is to evaluate floristic changes and above-ground primary production in native grasslands and old pastures dominated by tall fescue (Festuca arundinacea) that were fertilized with different levels of phosphorus. For this, aerial biomass was sequentially harvested from November 1998 to October 1999. Above-ground production of native grassland more than doubled (from 3000 to 7300 kg DM/ha) with the highest level of P through the increment of three naturalized species: the winter annual ryegrass (Lolium multiflorum) and two legumes: white clover (Trifolium repens) and lotus (Lotus corniculatus). In …

Vegetation Changes In Southeast Australian Temperate Grasslands, D. L. Garden, T. P. Bolger

IGC Proceedings (1977-2023)

In temperate areas of southeast Australia, the combined effects of tree clearing, grazing, application of fertilizer and the introduction of exotic species have modified the original grasslands. This paper describes these changes and attempts to explain them in terms of ecological principles derived from North American grasslands. Stability of the original grasslands appears to have been due to the lack of disturbance and the slow rates of nitrogen (N) cycling within them. Increased N cycling after disturbance has allowed invasion of species better adapted to higher N status, particularly exotic annual grasses and weeds. The present composition of grasslands, in …

Soil Biodiversity, Root Herbivory And Carbon And Nitrogen Cycling In Grassland Soils, R. Cook, L. A. Dawson, A. C. Gange, S. J. Grayston, P. J. Murray, A. M. Treonis

IGC Proceedings (1977-2023)

This paper describes research on the relationships between grassland management practices and the diversity of biological communities in soil. Observations are being made in field trials with applications of nitrogen and lime and of insecticide to an original diverse sward and to a single species grass re-seed. The treatments are designed to produce different degrees of diversity in communities of soil animals and microbes. Assessments are being made over three years of the effects on the populations, activity and diversity of root-feeding animals, arbuscular mycorrhizal fungi, soil bacteria, fungi and micro fauna, including nonplant feeding nematodes. Associated laboratory experiments assess …

Novel Biomarkers Of Ciliary Extracellular Vesicles Interact With Ciliopathy And Alzheimer’S Associated Proteins, Ashraf M. Mohieldin, Amal Alachkar, John R. Yates Iii, Surya M. Nauli

Pharmacy Faculty Articles and Research

Ciliary extracellular vesicles (ciEVs), released from primary cilia, contain functional proteins that play an important role in cilia structure and functions. We have recently shown that ciEVs and cytosolic extracellular vesicles (cyEVs) have unique and distinct biomarkers. While ciEV biomarkers have shown some interactions with known ciliary proteins, little is known about the interaction of ciEV proteins with proteins involved in ciliopathy and neurodegenerative disorders. Here, we reveal for the first time the protein-protein interaction (PPI) between the top five ciEVs biomarkers with ciliopathy and Alzheimer disease (AD) proteins. These results support the growing evidence of the critical physiological roles …

The Energetics Of Uniquely Human Subsistence Strategies, Thomas S. Kraft, Vivek V. Venkataraman, Ian J. Wallace, Alyssa N. Crittenden, Nicholas B. Holowka, Jonathan Stieglitz, Jacob Harris, David A. Raichlen, Brian Wood, Michael Gurven, Herman Pontzer

Anthropology Faculty Research

The suite of derived human traits, including enlarged brains, elevated fertility rates, and long developmental periods and life spans, imposes extraordinarily high energetic costs relative to other great apes. How do human subsistence strategies accommodate our expanded energy budgets? We found that relative to other great apes, human hunter-gatherers and subsistence farmers spend more energy but less time on subsistence, acquire substantially more energy per hour, and achieve similar energy efficiencies. These findings revise our understanding of human energetic evolution by indicating that humans afford expanded energy budgets primarily by increasing rates of energy acquisition, not through energy-saving adaptations such …

The Effect Of Parental Thermal Environment On Maternal Investment And Offspring Performance, Bianca Allegra Parodi

The Plymouth Student Scientist

As heat wave phenomena and thermal variance events increase in frequency and intensity, it is important to understand how the effect of exposure to constant elevated temperatures on fitness differs from the one of thermal fluctuations. This study aims to investigate how parental thermal environment affects maternal fitness measured as maternal investment and offspring performance. A wild population of the amphipod Gammarus chevreuxi was exposed to constant (15, 20 and 25 °C) or fluctuating (variable between 15 and 25 °C) thermal regimes and allowed to mate. Immediately after fertilization, mothers carrying eggs were transferred to common garden conditions (15 °C), …

Personalized Nutrition As A Key Contributor To Improving Radiation Response In Breast Cancer, Anuradha A. Shastri, Joseph Lombardo, Samantha C Okere, Stephanie Higgins, Brittany C Smith, Tiziana Deangelis, Ajay Palagani, Kamryn Hines, Daniel A. Monti, Stella Volpe, Edith P. Mitchell, Nicole L Simone

Department of Radiation Oncology Faculty Papers

Understanding metabolic and immune regulation inherent to patient populations is key to improving the radiation response for our patients. To date, radiation therapy regimens are prescribed based on tumor type and stage. Patient populations who are noted to have a poor response to radiation such as those of African American descent, those who have obesity or metabolic syndrome, or senior adult oncology patients, should be considered for concurrent therapies with radiation that will improve response. Here, we explore these populations of breast cancer patients, who frequently display radiation resistance and increased mortality rates, and identify the molecular underpinnings that are, …

Variations In Thermal Performance Of Cardiac Function Of Pure And Hybrid Mytilus Spp. As A Factor Influencing Hybrid Zone Dynamics, Isabelle Hann

The Plymouth Student Scientist

Interspecific hybridisation within the Mytilus complex has been well documented. Distribution patterns of Mytilus congeners in mosaic hybrid zones are hypothesised to reflect differences in their thermal tolerances. In this present study, the relative thermal performance of adult Mytilus galloprovincialis, Mytilus edulis and their hybrids, from a sympatric population within the Southwest England mosaic hybrid zone was assessed using cardiac function as a proxy for thermal performance. As indices of cardiac performance, the Arrhenius break temperature (ABT), the maximum heart rate, the slope post-ABT and the flat line temperature were used. Examination of the response of cardiac activity under emersion …

The Dark Tetrad Of Personality And The Tendency To Engage In Revenge Porn, Niamh Thomason-Darch

The Plymouth Student Scientist

Revenge porn is an increasing and pervasive phenomenon. Despite this, the knowledge and understanding of this behaviour is limited, especially the psychological characteristics of perpetrators of revenge porn. The Dark Tetrad of personality: Machiavellianism, psychopathy, narcissism, and sadism, has been associated with a range of antisocial behaviours. Recent research indicates a relationship between the Dark Tetrad and revenge porn proclivity. The present study extended these findings by investigating the relationship between revenge porn proclivity and the Dark Tetrad using more trait-specific measures. A community sample of 306 participants, aged 18-77, were recruited online. Participants completed a series of personality measures …

Variability In Epifaunal Assemblages Between Sargassum Muticum And Zostera Marina: A Functional Group Approach, Jenny Hickman

The Plymouth Student Scientist

Marine macrophytes are globally important to coastal ecosystems, providing refugia, nutrients and important ecological processes. The structure and composition of macrophytes have a bottom-up effect on the epifauna they support. Due to their wide-reaching effects, invasive algae are considered one of the greatest threats facing marine ecosystems. Sargassum muticum is a Japanese algae increasing its non-native range in coastal habitats globally. A highly dispersive algae, able to colonise soft substratum, it is considered a threat to seagrass beds across the North East Atlantic. In Salcombe Estuary, Devon, beds of Zostera marina have seen increasing levels of invasion by S. muticum. …

Does Cannabidiol (Cbd) Oil Convert To Psychotropic Cannabinoids Including Tetrahydrocannabinol?, Danielle Young

The Plymouth Student Scientist

Cannabidiol (CBD) is a non-psychotropic cannabinoid that belongs to the Cannabis Sativa L plant. This naturally occurring cannabinoid has gained huge interest in recent years because of the potential therapeutic and pharmacological effects it has upon ingestion and inhalation. Cannabidiol has not only been regarded as a medicinal product but is widely sold over the counter (OTC) in the form of concentrated oils, food supplements, cosmetics, and electronic cigarettes. Regulation of OTC products has proven difficult because of the narcotic nature of the cannabis plant and it has been advised that CBD might be degraded into psychotropic cannabinoids, namely tetrahydrocannabinol …

Treatment-Specific Hippocampal Subfield Volume Changes With Antidepressant Medication Or Cognitive-Behavior Therapy In Treatment-Naive Depression., Hua-Hsin Tai, Jungho Cha, Faezeh Vedaei, Boadie W Dunlop, W Edward Craighead, Helen S Mayberg, Ki Sueng Choi

Department of Neuroscience Faculty Papers

Background: Hippocampal atrophy has been consistently reported in major depressive disorder with more recent focus on subfields. However, literature on hippocampal volume changes after antidepressant treatment has been limited. The first-line treatments for depression include antidepressant medication (ADM) or cognitive-behavior therapy (CBT). To understand the differential effects of CBT and ADM on the hippocampus, we investigated the volume alterations of hippocampal subfields with treatment, outcome, and chronicity in treatment-naïve depression patients. Methods: Treatment-naïve depressed patients from the PReDICT study were included in this analysis. A total of 172 patients who completed 12 weeks of randomized treatment with CBT (n …

Analysis Of Some Farm Driving Variables And Its Relation With Milk Production In A Pastoral Dairy Farm Of Buenos Aires, Argentina, J. L. Rossi, A. Ayala Torales, G. Acosta, V. A. Deregibus

IGC Proceedings (1977-2023)

The quantity of milk solids produced determines a dairy farm income and contributes to its profit. Total pasture production, forage quality and herd consumption are factors to be managed in this production system. The outcomes of two years were analyzed. Primary production showed its dependence on climatic conditions and use of technological inputs. Forage quality was promoted through interseeding legumes, applying fertilizer and maintaining the pasture young and leafy. Total forage removed by the herd was similar in both years although pasture production decreased. It was possible to cope with seasonal variations in forage production, by varying the grazing pressure …

IGC Proceedings (1977-2023)

The experiment was conducted at UFSM-RS to quantify herbage losses in oat and Italian ryegrass mixture under continuous grazing by beef heifers. A continuous grazing method with variable stocking rate was utilized to maintain the same herbage mass, 1500 kg DM/ha, in all treatments. The treatments consisted of levels of energetic supplement (0, 0.7 and 1.4% of LW/day). The pasture was evaluated every 28 days, when forage not suitable for grazing was collected in points previously marked in experimental area. The daily losses of herbage mass were of 22.32, 18.98 and 21.16 kg of DM/ha/day, equivalent to 2.61, 1.91 and …

Rotational Grazing Increases Wool And Lamb Production From Phalaris-Subterranean Clover Pastures In South Eastern Australia, A. N. Thompson, D. Borg, J. F. Graham, J. Lamb, G. R. Saul

IGC Proceedings (1977-2023)

Wool and lamb production from different grazing systems was compared in a Mediterranean environment near Hamilton in southeastern Australia. The grazing systems were based on combinations of fertiliser inputs and grazing methods that could promote the growth and persistence of phalaris (Phalaris aquatica) and increase animal production compared to ‘typical’ unimproved pastures. In the first 2 years of this experiment, the most productive systems more than doubled ewe stocking rate and wool production, and more than trebled lamb production per hectare, compared to ‘typical’ unimproved pasture, low fertility, set-stocked systems. The change to a well fertilised phalaris/subterranean clover …

Shapeshifting Power: Indigenous Teachings Of Trickster Consciousness And Relational Accountability For Building Communities Of Care, Ionah M. Elaine Scully

The Seneca Falls Dialogues Journal

Difficult dialogues are necessary work in order for communities to form coalitions, yet often these dialogues pose challenges for engaging in long-term work for social justice and systemic change. Power dynamics, microaggressions, and discomfort unlearning power and privilege can make long-term collaboration difficult. It is for this reason I discuss thinking of coalitions as communities of care and offer practical strategies for collaborating differently for sustainable action. Using Indigenous epistemology and methodology, Indigenous feminist and Indigequeer scholarship, as well as Indigenous land-based pedagogy and storytelling, I offer interventions using trickster teachings or trickster consciousness which I describe as comprised of …

The Potential Impacts Of Climate Change On Avitourism To Islands: The Example Of Fair Isle, Scotland, Richard W. Butler Professor

International Journal of Islands Research

This paper discusses the potential impact of climate change upon a specific form of tourism, avitourism (birdwatching), and the resulting effects upon islands dependent upon this form of tourism. Bird populations, distributions and migratory patterns are all vulnerable to the impacts of global warming, extreme weather events and changes in the marine environment, as are the islands which provide their habitat. Avitourism is a lucrative and non-consumptive form of tourism that is of major importance to some small islands, particularly those that have unique indigenous breeding species and/or are visited by migrating species on a regular basis. A number of …

This study was conducted to determine the effect of probiotics, Lactobacillus acidophilus on the growth parameters of Mugil sp. fish, their approximate biochemical composition and the environmental conditions of their culture for 12 weeks in floating cages. Six hundreds of fish were randomly distributed in two groups of 100 fish in each floating cages (length of 1 m, width of 1 m, depth of 2 m) with an initial weight of 39.5± 0.2 g. The first group was fed with the control diet and the second group with probiotics diet. The results showed significant differences (P <0.05) between fish fed on probiotics diet and fish fed on control diet in weight gain (WG), relative growth rate (RGR) and food conversion rate (FCR). The weight gain in the probiotics group was 18.3 g, while in the control group was 12.2 g. There was no significant difference (P> 0.05) for the specific …

Influence Of Prolonged Serotonin And Ergovaline Pre-Exposure On Vasoconstriction Ex Vivo, Eriton E. L. Valente, David L. Harmon, James L. Klotz

Animal and Food Sciences Faculty Publications

Ergot alkaloid mycotoxins interfere in many functions associated with serotonergic neurotransmitters. Therefore, the objective was to evaluate whether the association of serotonin (5-hydroxytryptamine, 5-HT) and ergot alkaloids during a 24 h pre-incubation could affect the vascular contractile response to ergot alkaloids. To evaluate the effects of 24 h exposure to 5-HT and ergot alkaloids (ergovaline, ERV), two assays were conducted. The first assay determined the half-maximal inhibitory concentration (IC₅₀)following the 24 h pre-exposure period, while the second assay evaluated the effect of IC₅₀ concentrations of 5-HT and ERV either individually or in combination. There was an interaction …

Paving The Way For Mind-Reading: Reinterpreting "Coercion" In Article 17 Of The Third Geneva Convention, John Zarrilli

Duke Journal of Constitutional Law & Public Policy Sidebar

Mind-reading is no longer a concept confined to the world of science-fiction: "Brain reading technologies are rapidly being developed in a number of neuroscience fields." One obvious application is to the field of criminal justice: Mind-reading technology can potentially aid investigators in assessing critical legal questions such as guilt, legal insanity, and the risk of recidivism. Two current techniques have received the most scholarly attention for their potential in aiding interrogators in determining guilt: brain-based lie detection and brain-based memory detection. The growing ability to peer inside someone's mind raises significant legal issues. A number of American scholars, especially in …

Ferpa And State Open Records Laws: What The North Carolina Supreme Court Got Wrong In Dth Media Corp. V. Folt, And How Courts & Congress Can Take Measures To Reconcile Privacy And Access Interests, Danielle Siegel

Duke Journal of Constitutional Law & Public Policy Sidebar

Over the past few years, courts across the country have confronted a common scenario. Members of the public and media request records from a public university pertaining to its investigations of sexual assault and misconduct on campus. Then, media outlets contend they have a right to access these records under state open records laws. But the university claims that it cannot, or will not, disclose the records under the Family Educational Rights and Privacy Act of 1974 ("FERPA").

The media outlet then files suit to compel disclosure. This Note explores the competing privacy and access interests at stake in this …

Nutritional And Physiological Constraints Contributing To Limitations In Small Intestinal Starch Digestion And Glucose Absorption In Ruminants, Ronald J. Trotta, David L. Harmon, James C. Matthews, Kendall C. Swanson

Animal and Food Sciences Faculty Publications

Increased efficiency of nutrient utilization can potentially be gained with increased starch digestion in the small intestine in ruminants. However, ruminants have quantitative limits in the extent of starch disappearance in the small intestine. The objective is to explore the nutritional and physiological constraints that contribute to limitations of carbohydrate assimilation in the ruminant small intestine. Altered digesta composition and passage rate in the small intestine, insufficient pancreatic α-amylase and/or small intestinal carbohydrase activity, and reduced glucose absorption could all be potentially limiting factors of intestinal starch assimilation. The absence of intestinal sucrase activity in ruminants may be related to …
