Regenerative Agriculture Effects On Invertebrate And Bird Communities And Insect-Provided Ecosystem Services, Alex Michels Jan 2022

Regenerative Agriculture Effects On Invertebrate And Bird Communities And Insect-Provided Ecosystem Services, Alex Michels

Electronic Theses and Dissertations

Conventional agricultural practices can have unintended consequences on the environment and wildlife. Insects and birds are declining at rapid rates around the world, and the current conventional agricultural paradigm is a major driver through habitat loss and the intensification of production. Invertebrates in agroecosystems provide services to both farmers and the rest of society. Regenerative systems may promote the functioning of an agroecosystem by influencing invertebrate abundance, diversity, and ecosystem services and mitigate bird and insect declines through conservation practices that increase soil health, reduce disturbances, and increase biological diversity. Here I address knowledge gaps of the effects of regenerative …

Response Of Soil Biochemical And Physical Properties To Long Term Prairie Cordgrass And Kura Clover Intercropping System, Vaishnavi Varikuti Jan 2022

Response Of Soil Biochemical And Physical Properties To Long Term Prairie Cordgrass And Kura Clover Intercropping System, Vaishnavi Varikuti

Electronic Theses and Dissertations

Prairie cordgrass (Spartina pectinata) (PCG) is a warm-season perennial grass that can be used as a biofuel feedstock and can be grown on marginal lands. Previous studies on intercropping of a perennial legume i.e., kura clover (Trifolium ambiguum) (KC) with PCG can improve soil biochemical properties, increase biomass production, mitigate greenhouse gas (GHG) emissions while reducing the chemical fertilizer requirement. However, there is a lack of evidence about the effects of PCG production on soil biochemical and physical properties during the cropping season and at deeper soil depths in reference to support plant growth, environmental implications and enhance the soil …

Eastern Redcedar (Juniperus Virginiana L.) Encroachment On South-Central South Dakota Rangelands: Impact On Plant Communities, Austin K. Domeier Jan 2022

Eastern Redcedar (Juniperus Virginiana L.) Encroachment On South-Central South Dakota Rangelands: Impact On Plant Communities, Austin K. Domeier

Electronic Theses and Dissertations

Grasslands historically covered 46 million km2 of Earth’s surface representing nearly 42% of the living vegetation. Encroachment of woody species onto grasslands and savannas is a widely researched global phenomenon, with eastern redcedar (ERC) (Juniperus virginiana L.) trees being the most prominent woody encroacher in the Northern Great Plains (NGP) due to the lack of prescribed fire and planted ERC escaping from shelterbelts. This encroachment poses a threat to native plant communities in terms of their reproduction, regeneration, and diversity. ERC are fierce competitors and can establish in most soil types, are drought tolerant, and prolific seed reproducers. These qualities …

Living In A Gradient: The Influence Of Water Temperature Variation On Development, Settling Time And Survival Of Pallid Sturgeon Larvae In The Missouri River, Maria Elizabeth Erceg Jan 2022

Living In A Gradient: The Influence Of Water Temperature Variation On Development, Settling Time And Survival Of Pallid Sturgeon Larvae In The Missouri River, Maria Elizabeth Erceg

Electronic Theses and Dissertations

Pallid Sturgeon (Scaphirhynchus albus) are a federally endangered species experiencing widespread reproduction and recruitment failures. Recruitment failure is hypothesized to be caused by habitat modifications made to the Missouri River that disrupt connectivity and alter temperature profiles downstream of constructed dams. Hypolimnetic releases from Missouri River dams affect the temperature downstream, creating colder conditions during the downstream drifting phase for dispersing larvae. Understanding the influence of water temperature changes on larval development is crucial for recovery efforts. In this study, we evaluated the effects of water temperature daily heating rate on energy use, settling behavior, and growth rate of endogenously …

Seeing Red: Indigenous Land, American Expansion, And The Political Economy Of Plunder In North America, Eliot Fackler Jan 2022

Seeing Red: Indigenous Land, American Expansion, And The Political Economy Of Plunder In North America, Eliot Fackler

Civil War Book Review

Michael John Witgen "concludes that the geographical expansion of the United States, especially in the northern Great Lakes homelands of the Anishinaabeg, depended not so much on military violence or even the immediate physical removal of Indigenous peoples. Rather, conquest was facilitated by a ‘political economy of plunder’ in which a coercive and duplicitous treaty process combined with the debt claims made by Indian agents, traders, and merchants to systematically separate Native nations from their land and annuity payments”

When Hell Came To Sharpsburg: The Battle Of Antietam And Its Impact On The Civilians Who Called It Home, Annabelle Blevins Pifer

Civil War Book Review

Steven Cowie reveals what happened when the homefront became the battlefront in When Hell Came to Sharpsburg: The Battle of Antietam and its Impact on the Civilians Who Called it Home. Reviewer Annabelle Blevins Pifer writes that “from the beginning Cowie thrusts you into the lives of Sharpsburg residents” and demonstrates the town’s civilians had no choice but to become part of the war. The two armies interrupted their daily lives, caused damage to their property that was rarely remunerated, initiated ecological changes, and spread disease through their community. When Hell Came to Shaprsburg, Pifer writes, is “a …

Estrogen receptor–α (ERα) expressed by neurons in the ventrolateral subdivision of the ventromedial hypothalamic nucleus (ERαvlVMH) regulates body weight in females, but the downstream neural circuits mediating this biology remain largely unknown. Here we identified a neural circuit mediating the metabolic effects of ERαvlVMH neurons. We found that selective activation of ERαvlVMH neurons stimulated brown adipose tissue (BAT) thermogenesis, physical activity, and core temperature and that ERαvlVMH neurons provide monosynaptic glutamatergic inputs to 5-hydroxytryptamine (5-HT) neurons in the dorsal raphe nucleus (DRN). Notably, the ERαvlVMH → DRN circuit responds to changes in ambient temperature and nutritional states. We further showed …

Effects Of A Short-Term Cold Exposure On Circulating Micrornas And Metabolic Parameters In Healthy Adult Subjects, Marc Thibonnier, Sujoy Ghosh, Anne Blanchard

Division of Basic Science Faculty Publications

This discovery study investigated in healthy subjects whether a short-term cold exposure may alter circulating microRNAs and metabolic parameters and if co-expression networks between these factors could be identified. This open randomized crossover (cold vs no cold exposure) study with blind end- point evaluation was conducted at 1 center with 10 healthy adult male volunteers. Wearing a cooling vest perfused at 14°C for 2 h reduced the local skin temperature without triggering shivering, increased norepinephrine and blood pressure while decreasing copeptin, C-peptide and heart rate. Circulating microRNAs measured before and after wearing the cooling vest twice (4 time points) identified …

Dietary Considerations For Postmenopausal Women, Kara L. Marlatt, Linda A. Gilmore, Emily W. Flanagan, Leanne M. Redman

Clinical Research Faculty Publications

Midlife women commonly experience changes in cardiometabolic, physical, and psychosocial health because of menopause. Importantly, these health changes can negatively affect the overall quality of life. Specifically, women experience changes in metabolism and weight gain (particularly abdominal fat), bothersome vasomotor symptoms (i.e., hot flashes and night sweats), sleep disturbances, mood swings, and reduced bone health. Women may also experience social isolation, loneliness, and changes in gastrointestinal health, which can further reduce their quality of life. In this chapter, we summarize these important health changes and discuss various dietary and lifestyle considerations that healthcare professionals can employ to help their patients …

Body Composition And Cardiometabolic Health Across The Menopause Transition, Kara L. Marlatt, Dori R. Pitynski-Miller, Kathleen M. Gavin, Kerrie L. Moreau, Edward L. Melanson, Nanette Santoro, Wendy M. Kohrt

Clinical Research Faculty Publications

Every year, 2 million women reach menopause in the United States, and they may spend 40% or more of their life in a postmenopausal state. In the years immediately preceding menopause—known as the menopause transition (or perimenopause)—changes in hormones and body composition increase a woman’s overall cardiometabolic risk. In this narrative review, we summarize the changes in weight, body composition, and body fat distribution, as well as the changes in energy intake, energy expenditure, and other cardiometabolic risk factors (lipid profile, glucose metabolism, sleep health, and vascular function), that occur during the menopause transition. We also discuss the benefits of …

The Vegetarian/Flexitarian Diets, Derek Miketinas, Catherine M. Champagne Jan 2022

The Vegetarian/Flexitarian Diets, Derek Miketinas, Catherine M. Champagne

Population and Public Health Science Faculty Publications

Vegetarian diets are popular for their documented health benefits, ethical considerations, cost-effectiveness, and other perceived benefits. These diets can be nutritionally superior to the typical Western diet for reducing chronic disease risk including cardiovascular disease, obesity, certain cancers, and type 2 diabetes. Although the health benefits of vegetarian diets are well documented, they are comparable to other diets that do not necessarily restrict animal products, such as the Dietary Approach to Stop Hypertension (DASH) and Mediterranean diets. Restricting entire food groups can present nutritional concerns, including potentially inadequate intakes of some micronutrients; however, the clinical manifestations of such deficiencies are …

Effects Of Maternal Diabetes And Diet On Gene Expression In The Murine Placenta, Claudia Kappen, Claudia Kruger, J. Michael Salbaum Jan 2022

Effects Of Maternal Diabetes And Diet On Gene Expression In The Murine Placenta, Claudia Kappen, Claudia Kruger, J. Michael Salbaum

Division of Basic Science Faculty Publications

Adverse exposures during pregnancy have been shown to contribute to susceptibility for chronic diseases in offspring. Maternal diabetes during pregnancy is associated with higher risk of pregnancy complications, structural birth defects, and cardiometabolic health impairments later in life. We showed previously in a mouse model that the placenta is smaller in diabetic pregnancies, with reduced size of the junctional zone and labyrinth. In addition, cell migration is impaired, resulting in ectopic accumulation of spongiotrophoblasts within the labyrinth. The present study had the goal to identify the mechanisms underlying the growth defects and trophoblast migration abnormalities. Based upon gene expression assays …

Division of Basic Science Faculty Publications

Epidemiological and clinical studies have shown that exposure to particulate matter (PM) is associated with an increased incidence of lung cancer and metastasis. However, the underlying mechanism remains unclear. Here, we demonstrated the central role of PM-induced neutrophil recruitment in promoting lung cancer metastasis. We found that reactive oxygen species (ROS)-mediated alveolar epithelial macroautophagy/autophagy was essential for initiating neutrophil chemotaxis and pre-metastatic niche formation in the lungs in response to PM exposure. During PM-induced autophagy, the E3 ubiquitin ligase TRIM37 was degraded and protected TRAF6 from proteasomal degradation in lung epithelial cells, which promoted the NFKB-dependent production of chemokines to …

Habitat Segregation Patterns Of Container Breeding Mosquitos: The Role Of Urban Heat Islands, Vegetation Cover, And Income Disparity In Cemeteries Of New Orleans, Rebeca De Jesús Crespo, Rachel Elba Rogers

Faculty Publications

Aedes aegypti and Aedes albopictus are important pathogen-carrying vectors that broadly exhibit similar habitat suitability, but that differ at fine spatial scales in terms of competitive advantage and tolerance to urban driven environmental parameters. This study evaluated how spatial and temporal patterns drive the assemblages of these competing species in cemeteries of New Orleans, LA, applying indicators of climatic variability, vegetation, and heat that may drive habitat selection at multiple scales. We found that Ae. aegypti was well predicted by urban heat islands (UHI) at the cemetery scale and by canopy cover directly above the cemetery vase. As predicted, UHI …

Although Borneo has received more attention from biologists than most other islands in the Malay Ar-chipelago, many questions regarding the systematic relationships of Bornean mammals remain. Using next-generation sequencing technology, we obtained mitochondrial DNA sequences from the holotype of Suncus ater, the only known specimen of this shrew. Several shrews collected recently in Sarawak are closely aligned, both morphologically and mitochondrially, with the holotype of S. ater. Phylogenetic analyses of mitochondrial sequences indicate that the S. ater holotype and new Sarawak specimens do not belong to the genus Suncus, but instead are most closely related to Palawanosorex muscorum. Until now …

No Guts About It: Captivity, But Not Neophobia Phenotype, Influences The Cloacal Microbiome Of House Sparrows (Passer Domesticus), T. R. Kelly, A. E. Vinson, G. M. King, C. R. Lattin

Faculty Publications

Behavioral traits such as anxiety and depression have been linked to diversity of the gut microbiome in humans, domesticated animals, and lab-bred model species, but the extent to which this link exists in wild animals, and thus its eco- logical relevance, is poorly understood. We examined the relationship between a behavioral trait (neophobia) and the cloacal microbiome in wild house sparrows ( Passer domesticus, n = 22) to determine whether gut microbial diversity is related to per- sonality in a wild animal. We swabbed the cloaca immediately upon capture, assessed neophobia phenotypes in the lab, and then swabbed the cloaca …

Morphology Of Migration: Associations Between Wing Shape, Bill Morphology And Migration In Kingbirds (Tyrannus), Maggie P. Macpherson, Alex E. Jahn, Nicholas A. Mason Jan 2022

Morphology Of Migration: Associations Between Wing Shape, Bill Morphology And Migration In Kingbirds (Tyrannus), Maggie P. Macpherson, Alex E. Jahn, Nicholas A. Mason

Faculty Publications

Morphology is closely linked to locomotion and diet in animals. In animals that undertake long-distance migrations, limb morphology is under selection to maximize mobility and minimize energy expenditure. Migratory behaviours also interact with diet, such that migratory animals tend to be dietary generalists, whereas sedentary taxa tend to be dietary specialists. Despite a hypothesized link between migration status and morphology, phylogenetic comparative studies have yielded conflicting findings. We tested for evolutionary associations between migratory status and limb and bill morphology across kingbirds, a pan-American genus of birds with migratory, partially migratory and sedentary taxa. Migratory kingbirds had longer wings, in …

A Low-Cost Greenhouse-Based High-Throughput Phenotyping Platform For Genetic Studies: A Case Study In Maize Under Inoculation With Plant Growth-Promoting Bacteria, Rafael Massahiro Yassue, Giovanni Galli, Ronaldo Borsato, Hao Cheng, Gota Morota, Roberto Fritsche-Neto

Faculty Publications

Greenhouse-based high-throughput phenotyping (HTP) presents a useful approach for studying novel plant growth-promoting bacteria (PGPB). Despite the potential of this approach to leverage genetic variability for breeding new maize (Zea Mays L.) cultivars exhibiting highly stable symbiosis with PGPB, greenhouse-based HTP platforms are not yet widely used because they are highly expensive; hence, it is challenging to perform HTP studies under a limited budget. In this study, we built a low-cost greenhouse-based HTP platform to collect growth-related image-derived phenotypes. We assessed 360 inbred maize lines with or without PGPB inoculation under nitrogen-limited conditions. Plant height, canopy coverage, and canopy volume …

Genomic-enabled prediction models are of paramount importance for the successful implementation of genomic selection (GS) based on breeding values. As opposed to animal breeding, plant breeding includes extensive multienvironment and multiyear field trial data. Hence, genomic-enabled prediction models should include genotype × environment (G × E) interaction, which most of the time increases the prediction performance when the response of lines are different from environment to environment. In this chapter, we describe a historical timeline since 2012 related to advances of the GS models that take into account G × E interaction. We describe theoretical and practical aspects of those …
