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 …

Water Quality Of Madari Khal Tributary Of The Halda River, Chattogram, Bangladesh, Md. Shafiqul Islam, M.A. Azadi

Journal of Bioresource Management

Tidal canal Madari-Khal is one of the important tributaries of the river Halda, through which nearby hill stream water, agricultural washings, and effluents (treated or untreated) of Chattogram Asian paper Mill are drained to the Halda River. In this paper water quality and pollution level of Madari Khal are presented. A one-year study was conducted to ascertain the water quality and pollution level by using different physicochemical parameters i.e. Air temperature, Water temperature, Transparency, EC (Electrical Conductivity), TDS (Total Dissolved Solids), pH, DO (Dissolved Oxygen), freeCO₂, Ca⁺⁺ (Calcium), TH (Total Hardness), TA (Total Alkalinity), and Biological Oxygen …

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 …

Morphometric Analysis And Biochemical Estimation Of Wild Shrimps (Family: Penaeidae) Found In Coastal Waters Of Pakistan, Noor Us Saher, Syeda Hadiqa Noor

Journal of Bioresource Management

The world recognition of Seafood nutritional value for human consumption remain consistent throughout the time. Different informations and aspects have been studied and considered and generated various data sets but limited informations found about the biochemical concentration of various fishery species caught in the Pakistan. Therefore, the recent study design to evaluate the proximate levels of components in the edible component (flesh) of commercial shrimp species were studied. Four shrimp species; Fenneropenaeus indicus, Metapenaeopsis stridulans, Metapenaeus stebbingi, and Parapenaeopsis stylifera were selected for the assessment of proximate composition. The selected shrimp species were collected from the fishery catch of Korangi …

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 …

Linking Science And Literacy Through Multimodal Text Sets: Student Perspectives, Heba Abdelnaby, William L. Romine, Delinda Van Garderen, Tracey Milarsky, Ankita Agarwal, Qingli Lei, Cassandra Smith, Amy Lannin, William Folk, Rachel Juergensen

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

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

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 …

The Effects Of Chronic Hypercarbia On Morphological And Ventilatory Development In Crayfish, Cassandra Poeppelman, Josh Hivner, Lynn K. Hartzler

Festival of Research

Instances of abnormally high CO2 levels are becoming increasingly common in freshwater ecosystems undergoing eutrophication. Chronic hypercarbia (long-term elevation of the partial pressure of carbon dioxide (Pco2)) is pervasive in these eutrophic ecosystems. Elevated Pco2 increases the ventilation and metabolism of some tadpoles and aquatic frogs and hinders their morphological development23. We expect that chronic hypercarbia will affect most aquatic organisms in the same way, but it remains to be verified that chronic hypercarbic conditions also alter aquatic organisms similarly to intermittent and acute hypercarbic challenges.

Tracking The Progression Of Defects At The Neuromuscular Junction In Huntington's Disease, Katherine A. Trittschuh

Browse all Theses and Dissertations

Huntington’s disease (HD) is a genetic disorder associated with progressive cognitive and motor decline. Recent studies in HD models suggest primary peripheral pathologies arise independent of changes in the central nervous system. Our lab found defects in skeletal muscle occurring early in the progression of disease in transgenic R6/2 HD mice, resulting in membrane hyperexcitability. Additionally, there is evidence of decreased quantal content in late-stage R6/2 mice. Here, we investigate pre-synaptic and post-synaptic function at single neuromuscular junctions (NMJ) to make direct comparisons of disease progression in the muscle membrane and motor nerve terminal. We hypothesize that muscle membrane defects …
