Different species of bees provide essential ecosystem services by pollinating various agricultural crops, including tree fruits. Many fruits and nuts depend on insect pollination, primarily by wild and managed bees. In different geographical regions where orchard crops are grown, fruit growers rely on wild bees in the farmscape and use orchard bees as alternative pollinators. Orchard crops such as apples, pears, plums, apricots, etc., are mass-flowering crops and attract many different bee species during their bloom period. Many bee species found in orchards emerge from overwintering as the fruit trees start flowering in spring, and the active duration of these …

The fall armyworm (FAW), Spodoptera frugiperda (JE Smith, 1797), is a serious pest of several crops, particularly maize and other cereals. It has long been known as a pest in the Americas and has invaded most of Africa and parts of the Middle East, Asia, and Australia in the last six years. Its new status as an invasive species causing serious damage in many regions worldwide has highlighted the need for better understanding and has generated much research. In this article, we provide a comprehensive review of FAW covering its (i) taxonomy, biology, ecology, genomics, and microbiome, (ii) worldwide status …

Grant At 200: Reconsidering The Life And Legacy Of Ulysses S. Grant, Richard G. Mannion

Civil War Book Review

"As [Chris] Scaturro has suggested for years, the name Ulysses S. Grant indeed belongs in the Pantheon with the other greatest of American heroes. What had been written in his name for so long is a historical disgrace and a sad commentary of that bygone historical community. His 'reputational renaissance' is long overdue, and this piece of literature is just one more recent convincing development that will allow Grant to earn his just do."

Twitter As Limited Digital Rhetorical Forum – The Reproductive Rights Discourse Online, Jacob L. Longini

Comparative Woman

Rhetorical discourse has long been characterized by patriarchal systems, and this reality has persisted in online spaces. How might today’s scholar dissect and better understand the nature of online communities, specifically those that engage in women’s rights discourses? I argue that using Thomas Farrell’s notion of “rhetorical forum”, James P. Zappen’s outline for digital rhetorical theory, and Sonja K. Foss and Cindy L. Griffin’s feminist understanding of rhetorical practice, one can account for the current state of such discourses on Twitter. The patriarchal flaws that Foss and Griffin identify in traditional rhetoric can shed light on the negative aspects of …

This paper takes the texts, rituals and materials related to the Qiqiao festival to investigate its origin and evolution. First, it takes the anthological case of the Qiqiao festival in Xihe county to explore its core image of the holy bridge and Goddess Qiao. Second, it traces the bridge …

“By That Daughter’S Most Devoted Affection”: Anxious And Avoidant Attachments In Opie’S Adeline Mowbray, Meghan E. Hodges

Comparative Woman

Attachment theory, or the theory that one’s personality and social development is informed greatly by the infant-parent bond, largely arises in the 1950s with the work of John Bowlby. Although the phenomenon was only then beginning to be scientifically evaluated, it has long been observed that the relationship one has with one’s parents is a determinant factor in one’s development. This work investigates the impact of the failure to heal the insecure attachment Amelie Opie’s Adeline Mowbray (1808). Adeline, having grown up in her distant mother’s intellectual shadow, develops a neurotic attachment to her mother which causes romantic maladjustment in …

LSU AgCenter research has helped establish these practices, and extension agents assist producers in implementing them.

This issue of Louisiana Agriculture highlights the best management practices for many of the state’s most production areas. Aquaculture specialists detail how crawfish farms can save money while meeting best management practices, and sugarcane experts tell how the AgCenter is developing new varieties to …

Human Subthalamic Nucleus Neurons Differentially Encode Speech And Limb Movement, Karim Johari, Ryan M. Kelley, Kris Tjaden, Charity G. Patterson, Andrea H. Rohl, Joel I. Berger, Daniel M. Corcos, Jeremy D.W. Greenlee

Faculty Publications

Deep brain stimulation (DBS) of the subthalamic nucleus (STN), which consistently improves limb motor functions, shows mixed effects on speech functions in Parkinson’s disease (PD). One possible explanation for this discrepancy is that STN neurons may differentially encode speech and limb movement. However, this hypothesis has not yet been tested. We examined how STN is modulated by limb movement and speech by recording 69 single- and multi-unit neuronal clusters in 12 intraoperative PD patients. Our findings indicated: (1) diverse patterns of modulation in neuronal firing rates in STN for speech and limb movement; (2) a higher number of STN neurons …

Modern-Day Neanderthal Genetic Lifewriting, Interspecies Romance, And The Promise Of Multispecies Autoethnography, Travis Brisini

Faculty Publications

Advances in contemporary genetic science have reshaped the narratives whereby individuals and communities make sense of their personal, family, and communal histories. In this process, unknown connections have been revealed and familiar orthodoxies disrupted. This essay examines the consequences of a particularly unusual revelation - the dawning awareness of the presence of nonhuman and archaic human DNA in human genetic lines - for efforts at writing about identity and society. In this autoethnographic account, I examine my own genetic inheritance of Neanderthal DNA, and posit a performative concept of genetic life writing that begins to unpack the complexities of this …

The emergence of novel betacoronaviruses has posed significant financial and human health burdens, necessitating the development of appropriate tools to combat future outbreaks. In this study, we have characterized a human cell line, IGROV-1, as a robust tool to detect, propagate, and titrate betacoronaviruses SARS-CoV-2 and HCoV-OC43. IGROV-1 cells can be used for serological assays, antiviral drug testing, and isolating SARS-CoV-2 variants from patient samples. Using time-course transcriptomics, we confirmed that IGROV-1 cells exhibit a robust innate immune response upon SARS-CoV-2 infection, recapitulating the response previously observed in primary human nasal epithelial cells. We performed genome-wide CRISPR knockout genetic screens …

Rbp4-Gal4, A Germline Driver That Activates In Meiosis, Reveals Functions For Vcp In Spermatid Development, Tyler J. Butsch, Alyssa E. Johnson, K. Adam Bohnert

Faculty Publications

Valosin-containing protein (VCP) is a versatile and ubiquitously expressed AAA+ ATPase that regulates multiple stages of Drosophila spermatogenesis. While VCP has documented roles in mitotic spermatogonia and meiotic spermatocytes, it is also highly expressed in post-meiotic spermatids, suggesting potential late-stage developmental functions as well. However, tools to assess late-stage activities of pleiotropic spermatogenesis genes such as VCP are lacking. Available germline-specific Gal4 drivers activate in stem cells or spermatogonia; consequently, knocking down VCP using one of these drivers disrupts or blocks early germ-cell development, precluding analysis of VCP in later stages. A Gal4 driver that activates later in development, such …

Wooing “Willing Dupes”: The Bush Administration’S Use Of Emotional Language In The Drive Toward War With Iraq, Michael F. Russo

Faculty Publications

The publicly available texts of the George W. Bush administration from September 11, 2001, to March 19, 2003, as presented in The Public Papers of the Presidents of the United States, were analyzed for word frequency and the words themselves analyzed for emotional weight using the NRC Emotion Intensity Lexicon. Transcripts of six television news agencies (ABC, CBS, NBC, CNN, FOX, and PBS) were also analyzed for word frequency to determine the extent to which these agencies may have repeated and consequently amplified the rhetoric of the administration. Public opinion polling for this same period was examined in an …

Introduction: Educational attainment, widely used in epidemiologic studies as a surrogate for socioeconomic status, is a predictor of cardiovascular health outcomes. Methods: A two-stage genome-wide meta-analysis of low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), and triglyceride (TG) levels was performed while accounting for gene-educational attainment interactions in up to 226,315 individuals from five population groups. We considered two educational attainment variables: “Some College” (yes/no, for any education beyond high school) and “Graduated College” (yes/no, for completing a 4-year college degree). Genome-wide significant (p < 5 × 10−8) and suggestive (p < 1 × 10−6) variants were identified in Stage 1 (in up to 108,784 individuals) through genome-wide analysis, and those variants were followed up in Stage 2 studies (in up to 117,531 individuals). Results: In combined analysis of Stages 1 and 2, we identified 18 novel lipid loci (nine for LDL, seven for HDL, and two for TG) by two degree-of-freedom (2 DF) joint tests of main and interaction effects. Four loci showed significant interaction with educational attainment. Two loci were significant only in cross-population analyses. Several loci include genes with known or suggested roles in adipose (FOXP1, MBOAT4, SKP2, STIM1, STX4), brain (BRI3, FILIP1, FOXP1, LINC00290, LMTK2, MBOAT4, MYO6, SENP6, SRGAP3, STIM1, TMEM167A, TMEM30A), and liver (BRI3, FOXP1) biology, highlighting the potential importance of brain-adipose-liver communication in the regulation of lipid metabolism. An investigation of the potential druggability of genes in identified loci resulted in five gene targets shown to interact with drugs approved by the Food and Drug Administration, including genes with roles in adipose and brain tissue. Discussion: Genome-wide interaction analysis of educational attainment identified novel lipid loci not previously detected by analyses limited to main genetic effects.

In this study, the optimal combination of factors for lycopene extraction from tomato pomace was identified using response surface methodology. The best practically feasible results maximising both lycopene yield and antioxidant activity of the extract were obtained by applying a ratio of ethyl acetate to tomato waste of 35:1 (v/w), at a temperature of 55°C for 100 min of extraction. The extract was then added to the peanut oil to evaluate its oxidative stability during 60 days of …

Going With The Flow: The Supply And Demand Of Sediment Retention Ecosystem Services For The Reservoirs In Puerto Rico, R. De Jesus Crespo, M. Valladares-Castellanos, Volodymyr V. Mihunov, T. H. Douthat

Faculty Publications

Impounding surface waters in reservoirs is a major mechanism for providing water for human consumption, including potable water, hydroelectric power, and industrial uses. Building reservoirs incurs environmental and social costs, and therefore safeguarding their effectiveness and longevity is a concern of clear public interest. One factor that affects the longevity of reservoirs is sedimentation, a process exacerbated by land use conversion in upstream watershed areas. Despite the economic importance of preventing sedimentation in existing reservoirs, few consumers are aware of the natural features that provide sediment retention services and the relevance of their conservation in their daily lives. Moreover, managing …

The presence of predators can cause major changes in animal behavior, but how this interacts with hormonal state and brain activity is poorly understood. We gave female house sparrows (Passer domesticus) in post-molt condition an estradiol (n = 17) or empty implant (n = 16) for 1 week. Four weeks after implant removal, a time when female sparrows show large differences in neuronal activity to conspecific vs. heterospecific song, we exposed birds to either 30 min of conspecific song or predator calls, and video recorded their behavior. Females were then euthanized, and we examined neuronal activity using the expression of …
