    Mayflies (Ephemeroptera) and Their Contributions to Ecosystem Services
    (MDPI, 2019-06-14) Jacobus, Luke M.; Macadam, Craig R.; Sartori, Michel; Division of Science, IUPUI Columbus
    This work is intended as a general and concise overview of Ephemeroptera biology, diversity, and services provided to humans and other parts of our global array of freshwater and terrestrial ecosystems. The Ephemeroptera, or mayflies, are a small but diverse order of amphinotic insects associated with liquid freshwater worldwide. They are nearly cosmopolitan, except for Antarctica and some very remote islands. The existence of the subimago stage is unique among extant insects. Though the winged stages do not have functional mouthparts or digestive systems, the larval, or nymphal, stages have a variety of feeding approaches-including, but not limited to, collector-gatherers, filterers, scrapers, and active predators-with each supported by a diversity of morphological and behavioral adaptations. Mayflies provide direct and indirect services to humans and other parts of both freshwater and terrestrial ecosystems. In terms of cultural services, they have provided inspiration to musicians, poets, and other writers, as well as being the namesakes of various water- and aircraft. They are commemorated by festivals worldwide. Mayflies are especially important to fishing. Mayflies contribute to the provisioning services of ecosystems in that they are utilized as food by human cultures worldwide (having one of the highest protein contents of any edible insect), as laboratory organisms, and as a potential source of antitumor molecules. They provide regulatory services through their cleaning of freshwater. They provide many essential supporting services for ecosystems such as bioturbation, bioirrigation, decomposition, nutrition for many kinds of non-human animals, nutrient cycling and spiraling in freshwaters, nutrient cycling between aquatic and terrestrial systems, habitat for other organisms, and serving as indicators of ecosystem health. About 20% of mayfly species worldwide might have a threatened conservation status due to influences from pollution, invasive alien species, habitat loss and degradation, and climate change. Even mitigation of negative influences has benefits and tradeoffs, as, in several cases, sustainable energy production negatively impacts mayflies.

    Tailoring Dental Appointments for Neurodivergent Children
    (2025-05) Chelmella, Payton; Van Antwerp, Leah; Department of Occupational Therapy, School of Health and Human Sciences; Steele, Jaime
    Many neurodivergent children have a difficult time during their dental visits or cannot find a dental office willing to treat them. This doctoral capstone project aimed to give a local pediatric dentist office the information and experience they need to confidently provide care for neurodivergent patients and patients with dental anxiety. Six evidence-based themes about beneficial adaptations and modifications were addressed, including: acclimating to the dentist, desensitization, patient care beyond the chair, child behavior management, adaptive communication, and sensory processing. The capstone student provided the dental team with additional information during the project, but the above themes were emphasized the most. The dental team members completed a pre-survey (9 participants) and post-survey (8 participants) to evaluate their knowledge and confidence in three areas: general knowledge about adaptations and modifications, perceived knowledge about concepts relating to specific adaptations and modifications, and their confidence in implementing specific adaptations and modifications. The results show that the three categories had a statistically significant difference between pre-survey and post-survey results with a medium to large effect size. This project had a strong impact on the dental team’s knowledge and confidence in ways to treat their neurodivergent patients and patients with dental anxiety, therefore, this project shows that occupational therapy has a valuable place in pediatric dental settings.
