The Persistence Of Blue Ash In The Aftermath Of Emerald Ash Borer May Be Due To Adult Oviposition Preferences And Reduced Larval Performance, Don Cipollini, Emily Morton Nov 2023

The Persistence Of Blue Ash In The Aftermath Of Emerald Ash Borer May Be Due To Adult Oviposition Preferences And Reduced Larval Performance, Don Cipollini, Emily Morton

Biological Sciences Faculty Publications

  1. We examined the health of mature blue ash, Fraxinus quadrangulata, in two forests in southwestern Ohio in relation to that of mature white ash, F. americana, and examined the potential importance of oviposition preferences and larval resistance in the persistence of blue ash.
  2. Both blue ash and white ash were largely unaffected by emerald ash borer in 2012. By 2018, nearly 90% of the blue ash trees observed in these forests had full or nearly full canopies, as opposed to less than 20% of the white ash encountered in our studies. In 2021, blue ash maintained a …


Homeostatic Synaptic Plasticity Of Miniature Excitatory Postsynaptic Currents In Mouse Cortical Cultures Requires Neuronal Rab3a, Andrew G. Koesters, Mark M. Rich, Kathrin L. Engisch Sep 2023

Homeostatic Synaptic Plasticity Of Miniature Excitatory Postsynaptic Currents In Mouse Cortical Cultures Requires Neuronal Rab3a, Andrew G. Koesters, Mark M. Rich, Kathrin L. Engisch

Biological Sciences Faculty Publications

Following prolonged activity blockade, amplitudes of miniature excitatory postsynaptic currents (mEPSCs) increase, a form of homeostatic plasticity termed “synaptic scaling.” We previously showed that a presynaptic protein, the small GTPase Rab3A, is required for full expression of the increase in miniature endplate current amplitudes following prolonged blockade of action potential activity at the mouse neuromuscular junction in vivo (Wang et al., 2011), but it is unknown whether this form of Rab3A-dependent homeostatic plasticity shares any characteristics with central synapses. We show here that synaptic scaling of mEPSCs is impaired in mouse cortical neuron cultures prepared from Rab3A-/- and Rab3A Earlybird …


Gabaergic Synaptic Scaling Is Triggered By Changes In Spiking Activity Rather Than Transmitter Receptor Activation, Carlos Gonzalez-Islas, Zahraa Sabra, Ming-Fai Fong, Pernille Bülow, Nicholas Au Yong, Kathrin Engisch, Peter Wenner Jun 2023

Gabaergic Synaptic Scaling Is Triggered By Changes In Spiking Activity Rather Than Transmitter Receptor Activation, Carlos Gonzalez-Islas, Zahraa Sabra, Ming-Fai Fong, Pernille Bülow, Nicholas Au Yong, Kathrin Engisch, Peter Wenner

Biological Sciences Faculty Publications

Homeostatic plasticity represents a set of mechanisms that are thought to recover some aspect of neural function. One such mechanism called AMPAergic scaling was thought to be a likely candidate to homeostatically control spiking activity. However, recent findings have forced us to reconsider this idea as several studies suggest AMPAergic scaling is not directly triggered by changes in spiking. Moreover, studies examining homeostatic perturbations in vivo have suggested that GABAergic synapses may be more critical in terms of spiking homeostasis. Here we show results that GABAergic scaling can act to homeostatically control spiking levels. We find that increased or decreased …

We present findings of a mixed methods study examining the perceptions of students’ (with and without disabilities) understanding and engagement with multimodal STEM text sets. Exit slip and survey data were used to identify areas for improvement in the development of the multimodal STEM text sets for middle school students. Data were collected from 434 middle school students, 86 of whom had a disability, from six teachers’ classrooms in Spring 2021. Significant differences in perceptions of understanding of argumentation were reported between students with and without disabilities. However, ratings of the lessons and the quality of learning, as well as …


The Impact Of Study Strategies On Knowledge Growth And Summative Exam Performance In The First Year Of Medical School, Markia Black, William L. Romine, Molly Simonis, Jeffrey L. Peters, Volker Bahn, Amber Todd Apr 2023

The Impact Of Study Strategies On Knowledge Growth And Summative Exam Performance In The First Year Of Medical School, Markia Black, William L. Romine, Molly Simonis, Jeffrey L. Peters, Volker Bahn, Amber Todd

Biological Sciences Faculty Publications

Although the distinction between deep and surface processing strategies, their potential to differentially impact learning, and data supporting the superiority of deep processing strategies on summative exam scores are well supported by the literature, more work is needed to understand: (1) how medical students combine study strategies into learning practices, and (2) the effectiveness of these learning practices in facilitating knowledge gains as measured by standardized test scores.


Measuring Claim-Evidence-Reasoning Using Scenario-Based Assessments Grounded In Real-World Issues, William L. Romine, Amy Lannin, Ankita Agarwal, Maha Kareem, Emily Burwell Apr 2023

Measuring Claim-Evidence-Reasoning Using Scenario-Based Assessments Grounded In Real-World Issues, William L. Romine, Amy Lannin, Ankita Agarwal, Maha Kareem, Emily Burwell

Biological Sciences Faculty Publications

Improving students’ use of argumentation is front and center in the increasing emphasis on scientific practice in K-12 Science and STEM programs. We explore the construct validity of scenario-based assessments of claim-evidence-reasoning (CER) and the structure of the CER construct with respect to a learning progression framework. We also seek to understand how middle school students progress. Establishing the purpose of an argument is a competency that a majority of middle school students meet, whereas quantitative reasoning is the most difficult, and the Rasch model indicates that the competencies form a unidimensional hierarchy of skills. We also find no evidence …

Biological Sciences Faculty Publications

Freshwater harmful algal blooms (HABs), caused mostly by toxic cyanobacteria, produce a range of cyanotoxins that threaten the health of humans and domestic animals. Climate conditions and anthropogenic influences such as agricultural run-off can alter the onset and intensity of HABs. Little is known about the distribution and spread of freshwater HABs. Current sampling protocols in some lakes involve teams of researchers that collect samples by hand from a boat and/or from the shoreline. Water samples can be collected from the surface, from discrete-depth collections, and/or from depth-integrated intervals. These collections are often restricted to certain months of the year, …


Parasitism Of Corn Earworm, Helicoverpa Zea (Boddie) (Lepidoptera: Noctuidae), By Tachinid Flies In Cultivated Hemp, Armando Falcon-Brindis, John O. Stireman Iii, Zenaida J. Viloria, Raul T. Villanueva Jun 2022

Biological Sciences Faculty Publications

In a survey on hemp grown in western Kentucky we found an average of 27.8 CEW larvae per plant. We recorded 45% parasitism of CEW in these fields by two species of tachinid flies, Winthemia rufopicta and Lespesia aletiae. Most parasitized larvae were third to sixth instars at the time of collection. We found up to 22 tachinid eggs per host larva, 89% of which typically bore between 1 and 5 eggs on the thorax. 45.9% of CEW bearing eggs died. The number of tachinid eggs per host was unrelated to host body mass, but both the number of tachinid …


Variation In Student Perceptions Of Higher Education Course Quality And Difficulty As A Result Of Widespread Implementation Of Online Education During The Covid-19 Pandemic, Joseph Cavanaugh, Stephen J. Jacquemin, Christine Junker Apr 2022

Variation In Student Perceptions Of Higher Education Course Quality And Difficulty As A Result Of Widespread Implementation Of Online Education During The Covid-19 Pandemic, Joseph Cavanaugh, Stephen J. Jacquemin, Christine Junker

Biological Sciences Faculty Publications

The onset of the COVID-19 global pandemic affected higher education in a myriad of ways. One of the most notable effects however was the rapid and sudden transition of nearly all courses at most institutions to an online environment. And while there are a growing number of courses offered online already, this transition to nearly 100% remote education presented numerous challenges for instructors and students of face-to-face and hybrid style courses. Since student perceptions are closely tied to recruitment and retention, it is important to know if there are differences in student perceptions present in the way different courses are …


Measuring Science Teachers' Emotional Experiences With Evolution Using Real World Scenarios, William Lee Romine, Rutuja Mahajan, Amber Todd Dec 2021

Measuring Science Teachers' Emotional Experiences With Evolution Using Real World Scenarios, William Lee Romine, Rutuja Mahajan, Amber Todd

Biological Sciences Faculty Publications

Low acceptance of evolution remains an obstacle to quality biology instruction. We develop and utilize a novel assessment which measures emotional experience in light of real-world evolution education scenarios. We presented 296 science teachers 4 pro-evolution and 8 anti-evolution scenarios and asked them to rate their levels of joy, anger, sadness, fear, disgust, shame, and guilt elicited by that scenario on an ordinal 5-point scale. We used exploratory factor analysis to extract the most important dimensions in the teachers’ responses, Rasch analysis to explore the validity of the extracted subscales, and stepwise regression to find the most important factors driving …

Biological Sciences Faculty Publications

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 Jan 2021

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 …

Biological Sciences Faculty Publications

Garlic mustard is an invasive Eurasian biennial that has spread throughout the eastern United States and southern Canada. Populations of this plant vary in their susceptibility to Erysiphe cruciferarum, a causal agent of powdery mildew disease in Brassicaceous plants. We examined whether there were biogeographic patterns in the distribution of resistance in invasive North American and native European populations of this plant. We grew plants from 78 invasive and 20 native populations and screened them for powdery mildew resistance in the greenhouse. We found that populations were mostly monomorphic for either resistance or susceptibility but that some polymorphic populations …


Larval Performance Of A Major Forest Pest On Novel Hosts And The Effect Of Stressors, Donnie Lee Peterson, Don Cipollini Jan 2020

Larval Performance Of A Major Forest Pest On Novel Hosts And The Effect Of Stressors, Donnie Lee Peterson, Don Cipollini

Biological Sciences Faculty Publications

Novel hosts lacking a coevolutionary history with herbivores can often support improved larval performance over historic hosts; e.g., emerald ash borer [Agrilus planipennis (Fairmaire) Coleoptera: Buprestidae] on North American ash (Fraxinus spp.) trees. Whether trees are novel or ancestral, stress on plants increases emerald ash borer preference and performance. White fringetree [Chionanthus virginicus (L.) Lamiales: Oleaceae] and olive [Olea europaea (L.) Lamiales: Oleaceae] are closely related non-ash hosts that support development of emerald ash borer to adulthood, but their relative suitability as hosts and the impact of plant stress on larval success has not been well …


On The Potential For Saturated Buffers In Northwest Ohio To Remediate Nutrients From Agricultural Runoff, Stephen J. Jacquemin, Gregory J. Mcglinch, Theresa Dirksen, Angela Clayton Jan 2020

On The Potential For Saturated Buffers In Northwest Ohio To Remediate Nutrients From Agricultural Runoff, Stephen J. Jacquemin, Gregory J. Mcglinch, Theresa Dirksen, Angela Clayton

Biological Sciences Faculty Publications

Nutrient loading from nonpoint source runoff in the Midwest has emerged as one of the largest threats to water quality as the frequency of harmful algal blooms, hypoxic zones, and issues associated with human-resource interactions have risen abruptly over the past several decades. In this study, a saturated buffer ~500 m in length located in the western basin of the Lake Erie watershed was evaluated for its potential to reduce edge of field runoff and nutrient loading. Saturated buffers reduce runoff by routing subsurface tile drainage water into the riparian zone, providing an opportunity for drainage volume as well as …


The Missing Metric: An Evaluation Of Fungal Importance In Wetland Assessments, Megan A. Rúa Nov 2019

The Missing Metric: An Evaluation Of Fungal Importance In Wetland Assessments, Megan A. Rúa

Biological Sciences Faculty Publications

To preserve wetland ecosystem function, federal and state agencies have developed assessment procedures to better manage remaining wetland areas. Currently, wetland assessments do not consider microorganisms when determining wetland quality. This is notable, because fungi are often the primary decomposers of organic material and thus important players in nutrient cycling. The objective of this study is to quantify how wetland quality, as measured using the Ohio Rapid Assessment Method (ORAM), relates to fungal community composition. We sampled soils from six depressional emergent marshes in Ohio belonging to each of the three ORAM quality categories, assessed soil physicochemical properties, and recovered …


Genetically Distinct Behavioral Modules Underlie Natural Variation In Thermal Performance Curves, Gregory W. Stegeman, Scott E. Baird, William S. Ryu, Asher D. Cutter Jul 2019

Genetically Distinct Behavioral Modules Underlie Natural Variation In Thermal Performance Curves, Gregory W. Stegeman, Scott E. Baird, William S. Ryu, Asher D. Cutter

Biological Sciences Faculty Publications

Thermal reaction norms pervade organismal traits as stereotyped responses to temperature, a fundamental environmental input into sensory and physiological systems. Locomotory behavior represents an especially plastic read-out of animal response, with its dynamic dependence on environmental stimuli presenting a challenge for analysis and for understanding the genomic architecture of heritable variation. Here we characterize behavioral reaction norms as thermal performance curves for the nematode Caenorhabditis briggsae, using a collection of 23 wild isolate genotypes and 153 recombinant inbred lines to quantify the extent of genetic and plastic variation in locomotory behavior to temperature changes. By reducing the dimensionality of the …


Lakeshore Modification Reduces Secondary Production Of Macroinvertebrates In Littoral But Not Deeper Zones, Marlene Pätzig, Yvonne Vadeboncoeur, Mario Brauns Dec 2018

Lakeshore Modification Reduces Secondary Production Of Macroinvertebrates In Littoral But Not Deeper Zones, Marlene Pätzig, Yvonne Vadeboncoeur, Mario Brauns

Biological Sciences Faculty Publications

Littoral macroinvertebrates are an integral component of lake food webs, but their productivity may be affected by shoreline alteration. We hypothesized that human modification of lake shores simplifies habitat diversity, which, in turn, affects littoral macroinvertebrate production and patterns of depth–production relationships. Furthermore, we expected that lakeshore modification would favor nonnative species, potentially compensating for negative effects of lakeshore modification on production of native taxa. To test these ideas, we estimated benthic macroinvertebrate production in the upper littoral, middle littoral, and profundal zones of a large lowland lake (Lake Scharmützelsee) in Northeast Germany. We collected samples between April and November …


The Learning Loss Effect In Genetics: What Ideas Do Students Retain Or Lose After Instruction?, Amber Todd, William L. Romine Oct 2018

The Learning Loss Effect In Genetics: What Ideas Do Students Retain Or Lose After Instruction?, Amber Todd, William L. Romine

Biological Sciences Faculty Publications

Modern genetics is a relatively new domain, but it is increasingly important for students to have a firm grasp on the content, because genetic technologies are becoming more commonplace. In a previous study, we used the Learning Progression-based Assessment of Modern Genetics to assess high school students’ knowledge of genetics concepts after an intensive inquiry-based genetics instructional period. Given that this type of intensive inquiry-based instruction is unique, we are now investigating how students’ knowledge of genetics changes after instruction (i.e., learning loss effect). Using a six-measure longitudinal design, we found that students retained significant gains in five of the …

A Closer Look At The Items Within Three Measures Of Evolution Acceptance: Analysis Of The Mate, I-Sea, And Gaene As A Single Corpus Of Items, William L. Romine, Amber Todd, Emily M. Walter

Biological Sciences Faculty Publications

Background

Current direct Likert measures for evolution acceptance include the MATE, GAENE, and I-SEA. Pros and cons of each of these instruments have been debated, and yet there is a dearth of research teasing out their similarities and differences when they are used together in a single context beyond the fact that their measures tend to be highly correlated. We administered these to 452 college students in non-major biology classes at two research-intensive universities from the Midwestern and Western United States to investigate the measurement properties of the items within these instruments when combined as a single corpus.

Most plants engage in symbioses with mycorrhizal fungi in soils and net consequences for plants vary widely from mutualism to parasitism. However, we lack a synthetic understanding of the evolutionary and ecological forces driving such variation for this or any other nutritional symbiosis. We used meta-analysis across 646 combinations of plants and fungi to show that evolutionary history explains substantially more variation in plant responses to mycorrhizal fungi than the ecological factors included in this study, such as nutrient fertilization and additional microbes. Evolutionary history also has a different influence on outcomes of ectomycorrhizal versus arbuscular mycorrhizal symbioses; the former …

Maize lethal necrosis (MLN) has emerged as a serious threat to food security in sub-Saharan Africa. MLN is caused by coinfection with two viruses, Maize chlorotic mottle virus and a potyvirus, often Sugarcane mosaic virus. To better understand the dynamics of MLN and to provide insight into disease management, we modeled the spread of the viruses causing MLN within and between growing seasons. The model allows for transmission via vectors, soil, and seed, as well as exogenous sources of infection. Following model parameterization, we predict how management affects disease prevalence and crop performance over multiple seasons. Resource-rich farmers with …
