Inside Insects - Climate Change And Metamorphosis, Cailyn R. Mckay
Undergraduate Student Research Internships Conference
Climate change is causing extreme environmental conditions including an increase in the frequency of heat waves which have the potential to seriously impact insect species, particularly during the sedentary pupal stage. The true armyworm is used here as a model species to evaluate the effects of simulated heat waves on reproductive activity and output later in life. Heat waves had a negative impact on moth reproduction and could be impacting the ecology of the species today and in the future.
Assessing Methods For Enhancing Monarch Habitat In Re-Enrolling Crp Sites, Eva Van De Mortel, Tristan Murphy, Laura L. Jackson Ph.D.
Assessing Methods For Enhancing Monarch Habitat In Re-Enrolling Crp Sites, Eva Van De Mortel, Tristan Murphy, Laura L. Jackson Ph.D.
Summer Undergraduate Research Program (SURP) Symposium
Over the last 30 years, monarch butterflies and their habitats have been in dramatic decline. Land enrolled in the Conservation Reserve Program (CRP) is one of the greatest resources available to increase monarch population as it has the largest amount of space available for monarch habitat. However, some fields have lost the nectar plants and milkweeds necessary for monarch habitat. This study, asked how to best suppress vegetation in re-enrolling CRP land so that overseeded forbs have a better chance of survival? Vegetation surveys from 6 different sites in northeastern Iowa and results from 2021 to 2022 were compared. We …
Using Environmental Dna (Edna) To Assess Pollinator Communities In Cedar Valley, Mila Haynes, Brody Jack, Ai Wen Ph.D.
Using Environmental Dna (Edna) To Assess Pollinator Communities In Cedar Valley, Mila Haynes, Brody Jack, Ai Wen Ph.D.
Summer Undergraduate Research Program (SURP) Symposium
Tracking biological activity in Iowa prairies can prove difficult with such high levels of biodiversity. However, using environmental DNA (eDNA) collected from prairie flowers can provide integral information about the insects that pollinate various plants.
When bees land on flowers, they shed cells and leave trace amounts of their DNA behind. After extracting the DNA from these flowers using the Qiagen DNeasy Extraction method, the samples are then mixed with B10 primer. This primer allows only the bee DNA to be targeted once the samples are put through a Polymerase Chain Reaction (PCR).
The purpose of this study is to …
Evaluation Of Methods To Extract Genetic Material From Wild Bees, Brody Jack, Mila Haynes, Ai Wen Ph.D.
Evaluation Of Methods To Extract Genetic Material From Wild Bees, Brody Jack, Mila Haynes, Ai Wen Ph.D.
Summer Undergraduate Research Program (SURP) Symposium
Genetic studies on bees are essential to the understanding of the genetic and species diversity of bees, as well as general prairie health. Diversification of species and genetics are in decline, this means a decline in overall prairie health is inevitable. The University of Northern Iowa has ongoing studies looking into the health of prairies as well as the bee population, with a need for an understanding of how to properly store and extract genetic material from wild bees. We examined the concentration of DNA and fragment size shown in a gel from the bees that were killed using two …
Ant-Lanta: Ant Diversity As A Proxy For Ecosystem Health, Sofia Cuenca Rojas, John Paul Hellenbrand, Clint Penick
Ant-Lanta: Ant Diversity As A Proxy For Ecosystem Health, Sofia Cuenca Rojas, John Paul Hellenbrand, Clint Penick
Symposium of Student Scholars
Ants are found across a wide range of habitat types and play a crucial role in supporting ecosystem health. Because of this ubiquity, ants are considered an indicator species – one whose diversity in an ecosystem can be used as a proxy for ecosystem health. Our study examines the presence of ants across an urban gradient in Atlanta to understand how urbanization may be affecting our local community inhabitants. A total of 48 Sites were organized into three groups: Urban Managed Land, Urban Park, and Urban Forest. Sites were grouped based on ground cover percentages. We used bait samples to …
New Ant In The Big City: Known Natural History Of Lasius Cf. Emarginatus In Its Native Range And Potential Impacts Of Recent Us Introduction, Samantha M. Kennett, Clint A. Penick
New Ant In The Big City: Known Natural History Of Lasius Cf. Emarginatus In Its Native Range And Potential Impacts Of Recent Us Introduction, Samantha M. Kennett, Clint A. Penick
Symposium of Student Scholars
New York City has been the site of introduction for some of North America’s most damaging invasive pests, from chestnut blight to the Asian long-horned beetle. Despite these cautionary examples, there has been no formal tracking of a newly introduced ant species, Lasius cf. emarginatus, which has quickly become among the most common species in the city. Sometime between the first ant diversity survey of New York City in 2006 and the second in 2011,L. cf. emarginatus was introduced and quickly became established in the most urban habitats with the highest human contact. In contrast to other urban …

Urban Surveying Of Bees And Wasps And Conscious Management, Sofia Castro, Grace Cope, Francis Mullan, Jaden Keys
Symposium of Student Scholars
Pollinators are integral to the functioning of urban ecosystems and agriculture yet face decline from habitat loss and fragmentation associated with urbanization. Recently, a growing number of urban universities have taken steps to ensure their campuses support pollinators. Kennesaw State University (KSU) is a semi-urban school located in the unique ecological area between the biodiversity hotspot of the Southeastern Appalachians and the urban space of Atlanta, Georgia. Before the present study, no survey had been conducted to determine what pollinators and associated floral resources exist on the school’s grounds. Thus, we present the first inventory of pollinators and the floral …
Assessing The Influence Of Urban Greening On Urban Arthropods, Brendon Lawrence
Assessing The Influence Of Urban Greening On Urban Arthropods, Brendon Lawrence
Scholars Week
Green Heart is an urban greening experiment in Louisville, KY seeking to create new urban green spaces to ultimately increase air quality and improve human health. Changes in biodiversity in response to urban greening may influence human health via multiple hypothesized pathways including reducing harm (e.g. medicine provisioning), restoring capacities (e.g. reductions in stress), building capacities (e.g. increasing activity outdoors), and causing harm (e.g. zoonotic diseases). Arthropods are one component of diversity that may influence human health via each of these pathways. However, few studies have assessed the influence of Arthropod diversity on human health. Thus, the objective of our …
