Introduction: Alternative solutions in the form of herbal remedies meant to ease or expedite the process of labor have often been pursued and administered but have seldom been quantitatively tested for efficacy. Published research has shown some validation for some commonly used herbs such as blue cohosh (Caulophyllum thalictroides), red raspberry (Rubus idaeus), castor bean (Ricinus communis) and evening primrose (Oenothera biennis) on isolated mouse uterine strips. Methods: This study tested an array of herbs used by midwives in a labor induction tincture, which included black cohosh (Actaea racemosa), cramp bark (Viburnum opulus), partridgeberry (Mitchella repens), and motherwort (Leonurus cardiaca). …

Trackers for activity and physical fitness have become ubiquitous. Although recent work has demonstrated significant relationships between mental effort and physiological data such as skin temperature, heart rate, and electrodermal activity, we have yet to demonstrate their efficacy for the forecasting of mental effort such that a useful mental effort tracker can be developed. Given prior difficulty in extracting relationships between mental effort and physiological responses that are repeatable across individuals, we make the case that fusing self-report measures with physiological data within an internet or smartphone application may provide an effective method for training a useful mental effort tracking …

Tropical coastal waters are highly dynamic and amongst the most biogeochemically active zones in the ocean. This review compares nitrogen (N) and phosphorus (P) cycles in temperate and tropical coastal waters. We review the literature to identify major similarities and differences between these two regions, specifically with regards to the impact of environmental factors (temperature, sunlight), riverine inputs, groundwater, lateral fluxes, atmospheric deposition, nitrogen fixation, organic nutrient cycling, primary production, respiration, sedimentary burial, denitrification and anammox. Overall, there are some similarities but also key differences in nutrient cycling, with differences relating mainly to temperature, sunlight, and precipitation amounts and patterns. …

The scale and drivers of marine biodiversity loss are being revealed by the International Union for Conservation of Nature (IUCN) Red List assessment process. We present the first global reassessment of 1,199 species in Class Chondrichthyes-sharks, rays, and chimeras. The first global assessment (in 2014) concluded that one-quarter (24%) of species were threatened. Now, 391 (32.6%) species are threatened with extinction. When this percentage of threat is applied to Data Deficient species, more than one-third (37.5%) of chondrichthyans are estimated to be threatened, with much of this change resulting from new information. Three species are Critically Endangered (Possibly Extinct), representing …

Roles Matter: Graduate Student Perceptions Of Active Learning In The Stem Courses They Take And Those They Teach, Lorelei E. Patrick, Leigh Ann Howell, Everett William Wischusen
Biological Sciences Faculty Publications
Despite many calls to reform undergraduate science, technology, engineering, and math (STEM) education to incorporate active learning into classes, there has been little attention paid to graduate level classrooms or courses taught by graduate students. Here, we set out to understand if and how STEM graduate students’ perceptions of active learning change in the classes they take versus those they teach. We found that graduate students had taken relatively few graduate level classes using active learning and they felt that more time should be devoted to active learning in the courses they were taking. Teaching assistants felt that they were …

Inquiry-based laboratory activities, as a part of science curricula, have been advocated to increase students’ learning outcomes and improve students’ learning experiences, but students sometimes struggle with open-inquiry activities. This study aims to investigate students’ perceptions of inquiry-based learning in a set of laboratory activities, specifically from a psychological (i.e., Self-Determination Theory) perspective. Students’ ratings of the level of inquiry in these activities indicate that students’ perceptions of inquiry align with the instructor-intended amount of inquiry in each exercise. Students’ written responses, explaining their ratings, indicate that students’ perceptions of the amount of inquiry in a given lab exercise relate …

The interface between terrestrial ecosystems and inland waters is an important link in the global carbon cycle. However, the extent to which allochthonous organic matter entering freshwater systems plays a major role in microbial and higher-trophic-level processes is under debate. Human perturbations can alter fluxes of terrestrial carbon to aquatic environments in complex ways. The biomass and production of aquatic microbes are traditionally thought to be resource limited via stoichiometric constraints such as nutrient ratios or the carbon standing stock at a given timepoint. Low concentrations of a particular constituent, however, can be strong evidence of its importance in food …

Despite positive evidence for active learning (AL), lecturing dominates science, technology, engineering, and mathematics (STEM) higher education. Though instructors acknowledge AL to be valuable, many resist implementing AL techniques, citing an array of barriers including a perceived lack of student buy-in. However, few studies have explored student perceptions of specific AL teaching practices, particularly the perceptions of graduate students. We explored student-reported instructional strategies and student perceptions of and preferences for a variety of teaching practices in graduate and undergraduate classrooms across three STEM colleges at a large, public, research university. We found that both graduate and undergraduate students desired …

Biological Sciences Faculty Publications
Lake Tanganyika (LT) is the largest tropical freshwater lake, and the largest body of anoxic freshwater on Earth's surface. LT's mixed oxygenated surface waters float atop a permanently anoxic layer and host rich animal biodiversity. However, little is known about microorganisms inhabiting LT's 1470 meter deep water column and their contributions to nutrient cycling, which affect ecosystem-level function and productivity. Here, we applied genome-resolved metagenomics and environmental analyses to link specific taxa to key biogeochemical processes across a vertical depth gradient in LT. We reconstructed 523 unique metagenome-assembled genomes (MAGs) from 34 bacterial and archaeal phyla, including many rarely observed …

A Novel Thin-Film Technique To Improve Accuracy Of Fluorescence-Based Estimates For Periphytic Biofilms, Leon Katona, Yvonne Vadeboncoeur, Christopher T. Nietch, Katie Hossler
Biological Sciences Faculty Publications
Recent studies suggest that photophysiological parameters for intact substrates with depth (e.g., periphytic biofilms, microphytobenthos) are overestimated by pulse-amplitude modulated (PAM) fluorometry. This overestimation results from depth-integration effects, following the activation of deeper photosynthesizing layers by an attenuated light signal. To mitigate this error, we propose a novel slide-based thin-film technique in which fluorescence is measured on a vertically representative subsample of the biofilm, spread evenly on a microscope slide. We compared bias and precision for photosynthetic parameters estimated through conventional PAM fluorometry on intact biofilms and through our novel slide-based technique, both theoretically and empirically. Numerical simulations confirmed the …

Technological advances have allowed improvements in genome reference sequence assemblies. Here, we combined long- and short-read sequence resources to assemble the genome of a female Great Dane dog. This assembly has improved continuity compared to the existing Boxer-derived (CanFam3.1) reference genome. Annotation of the Great Dane assembly identified 22,182 protein-coding gene models and 7,049 long noncoding RNAs, including 49 protein-coding genes not present in the CanFam3.1 reference. The Great Dane assembly spans the majority of sequence gaps in the CanFam3.1 reference and illustrates that 2,151 gaps overlap the transcription start site of a predicted protein-coding gene. Moreover, a subset of …

Evolutionary Dynamics And Structural Consequences Of De Novo Beneficial Mutations And Mutant Lineages Arising In A Constant Environment, Margie Kinnersley, Katja Schwartz, Dong Dong Yang, Gavin Sherlock, Frank Rosenzweig
Biological Sciences Faculty Publications
Background: Microbial evolution experiments can be used to study the tempo and dynamics of evolutionary change in asexual populations, founded from single clones and growing into large populations with multiple clonal lineages. High-throughput sequencing can be used to catalog de novo mutations as potential targets of selection, determine in which lineages they arise, and track the fates of those lineages. Here, we describe a long-term experimental evolution study to identify targets of selection and to determine when, where, and how often those targets are hit. Results: We experimentally evolved replicate Escherichia coli populations that originated from a mutator/nonsense suppressor ancestor …

Evidence-based teaching practices (EBTP)—like inquiry-based learning, inclusive teaching, and active learning (AL)—have been shown to benefit all students, especially women, first-generation, and traditionally minoritized students in science fields. However, little research has focused on how best to train teaching assistants (TAs) to use EBTP or on which components of professional development are most important. We designed and experimentally manipulated a series of presemester workshops on AL, dividing subjects into two groups. The Activity group worked in teams to learn an AL technique with a workshop facilitator. These teams then modeled the activity, with their peers acting as students. In the …

Premise The genus Gynoxys and relatives form a species-rich lineage of Andean shrubs and trees with low genetic distances within the sunflower subtribe Tussilaginineae. Previous molecular phylogenetic investigations of the Tussilaginineae have included few, if any, representatives of this Gynoxoid group or reconstructed ambiguous patterns of relationships for it. Methods We sequenced complete plastid genomes of 21 species of the Gynoxoid group and related Tussilaginineae and conducted detailed comparisons of the phylogenetic relationships supported by the gene, intron, and intergenic spacer partitions of these genomes. We also evaluated the impact of manual, motif-based adjustments of automatic DNA sequence alignments on …

Biological Sciences Faculty Publications
In most flowering plants, the plastid genome exhibits a quadripartite genome structure, comprising a large and a small single copy as well as two inverted repeat regions. Thousands of plastid genomes have been sequenced and submitted to public sequence repositories in recent years. The quality of sequence annotations in many of these submissions is known to be problematic, especially regarding annotations that specify the length and location of the inverted repeats: such annotations are either missing or portray the length or location of the repeats incorrectly. However, many biological investigations employ publicly available plastid genomes at face value and implicitly …

Winter wheat (Triticum aestivum L.) is the most widely grown crop in Oklahoma and typically is planted in autumn and harvested in June. Wheat in Oklahoma is often infested by insect pests, the most important of which are the cereal aphids – greenbug, Schizaphis graminum (Rondani), and bird cherry-oat aphid, Rhopalosiphum padi (L.). We sampled a total of 69 wheat fields in central Oklahoma during five wheat-growing seasons. The number of wheat fields sampled ranged from seven in the 2016-2017 growing season to 24 fields in the 2009-2010 growing season. We used a D-vac suction sampler to collect aphids …

Biological Sciences Faculty Publications
Euchromatic histone-lysine N-methyltransferase 1 (EHMT1; G9a-like protein; GLP) and euchromatic histone-lysine N-methyltransferase 2 (EHMT2; G9a) are protein lysine methyltransferases that regulate gene expression and are essential for development and the ability of organisms to change and adapt. In addition to ankyrin repeats and the catalytic SET domain, the EHMT proteins contain a unique cysteine-rich region (CRR) that mediates protein-protein interactions and recruitment of the methyltransferases to specific sites in chromatin. We have determined the structure of the CRR from human EHMT2 by X-ray crystallography and show that the CRR adopts an unusual compact fold with four bound zinc atoms. The …

Karst features in the Silurian dolomites of Taylorsville MetroPark (Dayton Metropolitan Area, Ohio, United States) were explored from 2017 to 2018 to identify sites of paleontological interest. Initial landscape surveys recovered 124 skeletal elements (from 12 sites) that were attributed to 17 vertebrate species--including evidence of such extirpated animals as bobcats (Lynx rufus) and rattlesnakes (Crotalus sp.). Of the 12 sites, 9 sites contained remains from the historical era and 3 sites contained much older remains (n = 17) that were radiocarbon dated to approximately 1,400 years before present (YBP). Human remains at one site, butchered bones at another, and …

Evaluating Winter Malting Barley Grain Yield With Fractional Green Canopy Cover, Gregory J. Mcglinch, Stephen J. Jacquemin, Laura E. Lindsey
Biological Sciences Faculty Publications
Because of growth in the craft brewing industry, farmers in the eastern United States are planting winter malting barley (Hordeum vulgare L.) to meet demands for locally sourced grain. However, given that barley is a relatively new crop in this region, basic agronomic information relating to stand assessment is needed. This is particularly relevant in this region, as climatic variability from extreme temperature fluctuations during the winter and spring can reduce a barley stand, creating the need for farmers to estimate grain yield potential. The objective of the research was to evaluate the relationship between spring stem counts, fractional …

Corals from the northern Red Sea, in particular the Gulf of Aqaba (GoA), have exceptionally high bleaching thresholds approaching >5℃ above their maximum monthly mean (MMM) temperatures. These elevated thresholds are thought to be due to historical selection, as corals passed through the warmer Southern Red Sea during recolonization from the Arabian Sea. To test this hypothesis, we determined thermal tolerance thresholds of GoA versus central Red Sea (CRS) Stylophora pistillata corals using multi-temperature acute thermal stress assays to determine thermal thresholds. Relative thermal thresholds of GoA and CRS corals were indeed similar and exceptionally high (~7℃ above MMM). However, …

Tick-borne diseases are a growing problem in many parts of the world, and their surveillance and control touch on challenging issues in medical entomology, agricultural health, veterinary medicine, and biosecurity. Spatial approaches can be used to synthesize the data generated by integrative One Health surveillance systems, and help stakeholders, managers, and medical geographers understand the current and future distribution of risk. Here, we performed a systematic review of over 8,000 studies and identified a total of 303 scientific publications that map tick-borne diseases using data on vectors, pathogens, and hosts (including wildlife, livestock, and human cases). We find that the …

Biological Sciences Faculty Publications
Ixodes scapularis ticks transmit multiple pathogens, including Borrelia burgdorferi sensu stricto, and encode many proteins harboring epidermal growth factor (EGF)-like domains. We show that I. scapularis produces multiple orthologs for Bm86, a widely studied tick gut protein considered as a target of an anti-tick vaccine, herein termed as Is86. We show that Is86 antigens feature at least three identifiable regions harboring EGF-like domains (termed as EGF-1, EGF-2, and EGF-3) and are differentially upregulated during B. burgdorferi infection. Although the RNA interference-mediated knockdown of Is86 genes did not show any influences on tick engorgement or B. burgdorferi sensu stricto persistence, the …

The rising prevalence of tick-borne diseases in humans in recent decades has called attention to the need for more information on geographic risk for public health planning. Species distribution models (SDMs) are an increasingly utilized method of constructing potential geographic ranges. There are many knowledge gaps in our understanding of risk of exposure to tick-borne pathogens, particularly for those in the rickettsial group. Here, we conducted a systematic scoping review of the SDM literature for rickettsial pathogens and tick vectors in the genus Amblyomma. Of the 174 reviewed articles, only 24 studies used SDMs to estimate the potential extent …
Tetraspanins As Potential Therapeutic Candidates For Targeting Flaviviruses, Waqas Ahmed, Girish Neelakanta, Hameeda Sultana
Tetraspanins As Potential Therapeutic Candidates For Targeting Flaviviruses, Waqas Ahmed, Girish Neelakanta, Hameeda Sultana
Biological Sciences Faculty Publications
Tetraspanin family of proteins participates in numerous fundamental signaling pathways involved in viral transmission, virus-specific immunity, and virus-mediated vesicular trafficking. Studies in the identification of novel therapeutic candidates and strategies to target West Nile virus, dengue and Zika viruses are highly warranted due to the failure in development of vaccines. Recent evidences have shown that the widely distributed tetraspanin proteins may provide a platform for the development of novel therapeutic approaches. In this review, we discuss the diversified and important functions of tetraspanins in exosome/extracellular vesicle biology, virus-host interactions, virus-mediated vesicular trafficking, modulation of immune mechanism(s), and their possible role(s) …
