Taxonomic Notes On The Luciolinae (Coleoptera: Lampyridae), Oliver Keller, Lesley Ballantyne

Insecta Mundi

Several nomenclatural changes for taxa in the firefly subfamily Luciolinae (Coleoptera: Lampyri­dae) are proposed. Evidence is presented to correct the year of description for Luciola dregei Motschulsky 1853 to Motschulsky 1854 when the name was ratified. We correct the authorities and years of descriptions for type species designations for the genera Delopleurus Motschulsky, 1853, and Delopyrus Motschulsky, 1853 to Motschulsky 1854 for both. All remaining taxa described as variations in the subfamily Luciolinae by McDermott (1966), are evaluated to subspecies with their availability determined based on ICZN (1999) Article 45.6.

Temperature Fluctuation Alters Optimal Predator Community Composition For Anticipated Biological Control, Amanda N. Laubmeier, Nusrat Tabassum, Brigitte Tenhumberg

School of Biological Sciences: Faculty Publications

Alongside pesticides and specialist predators, natural communities of generalist beetle and spider predators play an important role in suppressing agricultural pests. However, the predation pressure of natural communities can be unpredictable. Overall predation pressure is influenced by a dense network of potential intraguild interactions, which are further shaped by species traits and environmental factors. Understanding how these different influences combine to impact pest control is especially important in the context of changing global temperatures. Recent empirical studies have demonstrated that the foraging behavior of arthropod predators is influenced by an interaction between temperature and predator body size. To explore the …

The Association Of Blood Ctdna Levels To Mutations Of Marker Genes In Colorectal Cancer, Fei Bai, Qian Du, Qingliang Zou, Lin Xu, Wei Dong, Xinlin Lv, Xiaorong Han, Huijun Zhou, Chi Zhang, Tao Lu

School of Biological Sciences: Faculty Publications

Background: Colorectal cancer (CRC) is a deadly and commonly diagnosed cancer. Cell‐free circulating tumor DNAs (ctDNA) have been used in the diagnosis and treatment of CRC, but there are open questions about the relationship between ctDNAs and CRC. Although mutations of genes detected by ctDNA in CRC have been studied, the quantitative relationship between ctDNA mutations and ctDNA concentration has not been addressed.

Aims: We hypothesized that there was an association between mutations of genes identified in ctDNAs and ctDNA concentration. His study examined this association in a population of CRC patients.

Methods: In 85 CRC patients, …

A New Species Of Biclonuncaria Razowski And Becker, 1993 (Lepidoptera: Tortricidae: Polyorthini) From Costa Rica, John W. Brown

Insecta Mundi

Biclonuncaria recurvana, new species (Lepidoptera: Tortricidae: Polyorthini), is described and il­lustrated from Area de Conservación Guanacaste in northwestern Costa Rica. It is most similar to B. conica Razowski, 1993, from Mexico, but the two are easily distinguished by features of the male genitalia. Biclo­nuncaria recurvana has been reared (n = 12 specimens) from field-collected larvae feeding on the leaves of Dalbergia glomerata Hemsley (Fabaceae), consistent with the previously reported host plant for B. dalbergiae Razowski and Becker, 1993, which has been reared from Dalbergia in Brazil.

Cellular Zinc Deficiency Impairs Heme Biosynthesis In Developing Erythroid Progenitors, Juyoung Kim, Jaekwon Lee, Moon-Suhn Ryu

Department of Biochemistry: Faculty Publications

Anemia is the most prevalent nutrition-related disorder worldwide. Zinc is an essential trace element for various biological processes in the body, and zinc deficiency has been associated with anemia in humans. However, the molecular mechanisms by which zinc availability alters red blood cell development remain uncertain. The present study identifies the essentiality of zinc during erythroid development, particularly for normal heme biosynthesis. G1E-ER4 mouse cells were used as an in vitro model of terminal erythroid differentiation, which featured elevated cellular zinc content by development. Restriction of zinc import compromised the rate of heme and -globin production and, thus, the hemoglobinization …

SCARB1 belongs to class B of Scavenger receptors (SRs) that are known to be involved in binding and endocytosis of various pathogens. SRs have emerging role in regulating innate immunity and host–pathogen interactions by acting in co-ordination with Toll-like receptors.Query Little is known about the function of SCARB1 in milk-derived mammary epithelial cells (MECs). This study reports the role of SCARB1 in infection and its potential association in TLR4 signaling on bacterial challenge in Goat mammary epithelial cells (GMECs). The novelty in the establishment of MEC culture lies in the method that aims to enhance the viability of the cells …

Editorial: Genetic Validation And Its Role In Crop Improvement, Ahmed Sallam, Ahmad M. Alqudah, P. Stephen Baenziger, Awais Rasheed

Department of Agronomy and Horticulture: Faculty Publications

Gene discovery for economically important traits has remained a challenging Frontier in crop genomics and breeding. The recent advances in DNA sequencing technologies and genetic analysis approaches paved the way for discovering many genes and hotspot genomic regions controlling target traits. The detection of novel genomic regions or candidate genes is very useful for plant breeders and geneticists to improve crops, dissect the genetics of complex traits, and understand the biological mechanisms of genes underpinning traits of interest. Quantitative trait loci (QTL) mapping and genome-wide association studies (GWAS) dominated recent crop gene discovery research. These studies are becoming routine activities …

The Intertwining Of Zn-Finger Motifs And Abiotic Stress Tolerance In Plants: Current Status And Future Prospects, Debojyoti Moulick, Karma Landup Bhutia, Sukamal Sarkar, Anirban Roy, Udit Nandan Mishra, Biswajit Pramanick, Sagar Maitra, Tanmoy Shankar, Swati Hazra, Milan Skalicky, Marian Brestic, Viliam Barek, Akbar Hossain

Department of Agronomy and Horticulture: Faculty Publications

Environmental stresses such as drought, high salinity, and low temperature can adversely modulate the field crop’s ability by altering the morphological, physiological, and biochemical processes of the plants. It is estimated that about 50% + of the productivity of several crops is limited due to various types of abiotic stresses either presence alone or in combination (s). However, there are two ways plants can survive against these abiotic stresses; a) through management practices and b) through adaptive mechanisms to tolerate plants. These adaptive mechanisms of tolerant plants are mostly linked to their signalling transduction pathway, triggering the action of plant …

Role Of Social Network On Technology Adoption: Application To Nebraska Producers In The Face Of Undesirable Vegetation Transitions, Sabrina Gulab, Holly K. Nesbitt, Simanti Banerjee, Theresa Floyd, Karina A. Schoengold

Cornhusker Economics

Conclusion

Producers need to have access to information regarding new conservation practices and technologies to ensure land management in the face of ecological threats in general and vegetation transitions (VTs) in the context of our study. This study investigates the role of an individual producer's social network on the willingness to seek information about technologies and management practices and the likelihood of new technology adoption with special attention to risk attitudes and producer spillover effects. Our results provide evidence that network composition and information obtained through a producer's social network don't influence an individual's willingness to seek information about new …

Comparative Transcriptome Analysis Of Tolerant And Sensitive Genotypes Of Common Bean (Phaseolus Vulgaris L.) In Response To Terminal Drought Stress, Mayavan Subramani, Carlos Urrea, Rasheed Habib, Ketaki Bhide, Jyothi Thimmapuram, Venu Kalavacharla

Panhandle Research and Extension Center

We conducted a genome-wide transcriptomic analysis of three drought tolerant and sensitive genotypes of common bean to examine their transcriptional responses to terminal drought stress. We then conducted pairwise comparisons between the root and leaf transcriptomes from the resulting tissue based on combined transcriptomic data from the tolerant and sensitive genotypes. Our transcriptomic data revealed that 491 (6.4%) DEGs (differentially expressed genes) were upregulated in tolerant genotypes, whereas they were downregulated in sensitive genotypes; likewise, 396 (5.1%) DEGs upregulated in sensitive genotypes were downregulated in tolerant genotypes. Several transcription factors, heat shock proteins, and chaperones were identified in the study. …

Subgenera Of Dacne Latreille, 1797 (Erotylidae: Erotylinae: Dacnini) Given Full Generic Rank, Paul E. Skelley

Insecta Mundi

Previously described subgenera of Dacne Latreille, 1797 (Coleoptera: Erotylidae) show charac­ter states and combinations implying closer relationships with genera other than with Dacne, suggesting “Dacne” is not monophyletic. These characters are briefly discussed along with the genera sharing the charac­ters. To improve the current classification, the subgenera of Dacne are raised to generic status as: Afrodacne Delkeskamp, 1954, Ameridacne Skelley, 2009, and Xenodacne Boyle, 1956. A checklist of all species included in these genera is presented, updating generic combinations as needed.

Clustering Climate And Management Practices To Define Environmental Challenges Affecting Gastrointestinal Parasitism In Katahdin Sheep, Brian C. Arisman, Joan M. Burke, James L. M. Morgan, Ronald M. Lewis

Department of Animal Science: Faculty Publications

Gastrointestinal nematodes (GIN) negatively affect the performance and well-being of sheep. Due to anthelmintic resistance, GIN are difficult to control leading producers to choose breeds that can exhibit resistance to parasitism. An example is Katahdin sheep. Katahdins are raised in various climates and management systems in the United States. These environmental factors can be combined to form eco-management groupings or clusters. We hypothesized that GIN challenge varies predictably based on the characteristics of these environmental clusters. Forty Katahdin producers from across the United States were surveyed for management information, with body weights (BW), fecal egg counts (FEC), and FAMACHA scores …

Effects Of High-Pressure Processing On Cooked Color And Eating Qualities Of Dark-Cutting Beef, Cole Reesman, Gary Sullivan, Mary-Grace C. Danao, Gretchen G. Mafi, Morgan Pfeiffer, Ranjith Ramanathan

Department of Animal Science: Faculty Publications

High meat pH leads to an undercooked or an abnormal pink appearance in fully-cooked product. High-pressure processing (HPP) promotes protein denaturation. The objective was to evaluate the effects of HPP on cooked steak color and sensory attributes of dark-cutting beef. USDA Choice (mean pH = 5.5) and dark-cutting (mean pH = 6.3) strip loin sections were vacuum packaged and treated with 0 (no HPP), 300, 450, and 600 MPa of pressure for 90 s using chilled water. Steaks were randomly assigned to measure external cooked color, Warner- Bratzler shear force, and trained sensory panel. Applying 300 MPa of pressure improved …

Nationwide Assessment Of Leadership Development For Graduate Students In The Agricultural Plant Sciences, Karen Ferreira Da Silva, Ella Burnham, Joe Louis, Douglas Golick, Sydney E. Everhart

Department of Plant Pathology: Faculty Publications

Leadership development is a universally important goal across the agricultural plant science disciplines. Although previous studies have identified a need for leadership skills, less is known about leadership skill development in graduate programs. To address this, we constructed a mixed-method study to identify the most significant graduate school leadership experiences of scientists in the agricultural plant science disciplines. The survey was deployed to 6,728 people in the U.S. and received 1,086 responses (16.1% response rate). The majority of respondents reported that they were from one of the major agricultural states and employed at one of the agricultural plant science related …

Identification And Biosynthetic Study Of The Siderophore Lysochelin In The Biocontrol Agent Lysobacter Enzymogenes, Amanda Lynn Miller, Shanren Li, Catherine D. Eichhorn, Yongbiao Zheng, Liangcheng Du

Liangcheng Du Publications

Lysobacter is a genus of bacteria emerging as new biocontrol agents in agriculture. Although iron acquisition is essential for the bacteria, no siderophore has been identified from any Lysobacter. Here, we report the identification of the first siderophore, N1,N8-bis(2,3-dihydroxybenzoyl)spermidine (lysochelin), and its biosynthetic gene cluster from Lysobacter enzymogenes. Intriguingly, the deletion of the spermidine biosynthetic gene encoding arginine decarboxylase or SAM decarboxylase eliminated lysochelin and the antifungals, HSAF and its analogues, which are key to the disease control activity and to the survival of Lysobacter under oxidative stresses caused by excess iron. The production of …

Panarchy Theory For Convergence, Shana M. Sundstrom, David G. Angeler, Jesse Bell, Michael J. Hayes, Jennifer Hodbod, Babak Jalalzadeh‑Fard, Rezaul Mahmood, Elizabeth Vanwormer, Craig R. Allen

School of Natural Resources: Faculty Publications

Coping with surprise and uncertainty resulting from the emergence of undesired and unexpected novelty or the sudden reorganization of systems at multiple spatiotemporal scales requires both a scientific process that can incorporate diverse expertise and viewpoints, and a scientific framework that can account for the structure and dynamics of interacting social-ecological systems (SES) and the inherent uncertainty of what might emerge in the future. We argue that combining a convergence scientific process with a panarchy framework provides a pathway for improving our understanding of, and response to, emergence. Emergent phenomena are often unexpected (e.g., pandemics, regime shifts) and can be …

Sitoki, Zachary A. Kwena, Zachary Ogari, Jared Babu Miruka, Ame Xiong, Chelsea Weirich, Christopher Mulanda Aura, Todd Rex Miller

School of Natural Resources: Faculty Publications

Lake Victoria, bordered by Kenya, Tanzania, and Uganda, provides one of the largest freshwater fisheries in the world and supports millions in small-scale fishing communities. Historical environmental change, including population growth, nutrient loading, introduced invasive species, and rising temperatures, has resulted in eutrophication and persistent cyanobacterial harmful algae blooms (cyanoHABs) over recent decades, particularly in the shallower gulfs, bays, and inlets. CyanoHABs impact fisheries and food web dynamics and compromise food and water security for nearshore fisher populations. In this study, we examine the socialecological impact of freshwater blooms on fisher health in one of these eutrophic regions, Winam Gulf …

Panta Rhei Benchmark Dataset: Socio-Hydrological Data Of Paired Events Of Floods And Droughts, Heidi Kreibich, Elliot Wickham, Et Al.

School of Natural Resources: Faculty Publications

As the adverse impacts of hydrological extremes increase in many regions of the world, a better understanding of the drivers of changes in risk and impacts is essential for effective flood and drought risk management and climate adaptation. However, there is currently a lack of comprehensive, empirical data about the processes, interactions, and feedbacks in complex human–water systems leading to flood and drought impacts. Here we present a benchmark dataset containing socio-hydrological data of paired events, i.e. two floods or two droughts that occurred in the same area. The 45 paired events occurred in 42 different study areas and cover …

Revisiting The Carbon–Biodiversity Connection, John Gamon

School of Natural Resources: Faculty Publications

This article is a Commentary on Schuldt et al., https://doi.org/10.1111/gcb.16697

The link between biodiversity and ecosystem function has long been a subject of intense interest and debate among biologists, going back to the time of Charles Darwin, whose ideas on species interactions presaged subsequent discussions of biodiversity and ecosystem function (Peterson et al., 1998). Since then, many considerations of community diversity have centered on the importance of species or functional diversity for maintaining system resilience in the face of disturbance, analogous to the way that interwoven threads maintain the function and integrity of fabric. While our language, concepts, and methods …

Connecting Distinct Realms Along Multiple Dimensions: A Meta-Ecosystem Resilience Perspective, David G. Angeler, Jani Heino, Juan Rubio-Ríos, J. Jesús Casas

School of Natural Resources: Faculty Publications

Resilience research is central to confront the sustainability challenges to ecosystems and human societies in a rapidly changing world. Given that social-ecological problems span the entire Earth system, there is a critical need for resilience models that account for the connectivity across intricately linked ecosystems (i.e., freshwater, marine, terrestrial, atmosphere). We present a resilience perspective of meta-ecosystems that are connected through the flow of biota, matter and energy within and across aquatic and terrestrial realms, and the atmosphere. We demonstrate ecological resilience sensu Holling using aquatic-terrestrial linkages and riparian ecosystems more generally. A discussion of applications in riparian ecology and …

Globally Scalable Approach To Estimate Net Ecosystem Exchange Based On Remote Sensing, Meteorological Data, And Direct Measurements Of Eddy Covariance Sites, Ruslan Zhuravlev, Andrey Dara, André Luís Diniz Dos Santos, Oleg Demidov, George Burba

Daugherty Water for Food Global Institute: Faculty Publications

Despite a rapid development of Nature-Based Solutions (NBS) for carbon removal in recent years, the methods for evaluating NBS still have certain gaps. We propose an approach based on a combination of remote sensing data and meteorological variables to reconstruct the spatiotemporal variation of net ecosystem exchange from eddy-covariance stations. A Lagrangian particle dispersion model was used for upscaling satellite images and flux towers. We trained data-driven models based on kernel methods separately for each selected land-cover class. The results suggest that the proposed approach to quantifying carbon exchange on a medium-to-large scale by blending eddy covariance flux data with …

“Popping It” As Family In Mosquitoes & Me: Affective Accumulation And Anzaldúan Aesthetic Consciousness In Ciencia Zurda, Katherine R. Bruna, Jennifer Farley, Lyric Bartholomay

University of Nebraska Public Policy Center: Publications

This article uses key concepts of Anzaldúan philosophy to describe the Mosquitoes & Me summer camp as ciencia zurda or left-handed science. It details a day-in-the-life portrait of Elena, a first-generation Latina middle schooler, as she experiences the opportunities that Mosquitoes & Me provided for self-other bridge crossing and radically relational, Nepantlan potential. Our discussion of Elena’s experiences in terms of Nepantlan principles of diversity, Affect, and spirit, as well as Affective accumulation and aesthetic consciousness, infuse an emotional and spiritual dimension to inquiry science- and responsive sciencecomplementarity and revisit a call for soul-centered, socially-transformative science.
