Scholar Week 2016 - present

Presentation Location: Weber Center, Room 101

Abstract

In 2014, the invasive Oriental weather loach was found in the Prairie Creek wetland at Midewin National Tallgrass Prairie. While little is known about the Oriental weather loach and its impact on freshwater ecosystems it has become a widespread invasive species. Being the first to investigate the impact of the Oriental weather loach on the Grant Creek and Prairie Creek watersheds at Midewin National Tallgrass Prairie, we set traps for specimens from early June till late July in both watersheds. Each loach that was caught was euthanized and dissected in order to understand ...

B10: Controlling Saltwater Intrusion: Aiding The Recovery Of Freshwater Ecosystems, Willem Maniago, Stefanie Whitmire, Dan Hitchcock

Annual Research Symposium

As sea levels rise, it is imperative to understand the effects of saltwater intrusion on freshwater ecosystems. This is especially true in the coastal wetlands of the SE US, where freshwater forests are dying from exposure to salinity. One management strategy that could prevent salinity intrusion in surface waters are water control structures (WCS). The Great Reserve, located outside of Georgetown, SC, represents a biodiverse freshwater forested wetland affected by saltwater intrusion from the adjacent tidal Black River. Several years ago, scientists and landowners observed the degradation of the ecosystem. The owners of the property installed a WCS at the ...


Impact Of Whitetail Deer Overpopulation With Hunting On The Decline, Matthew J. Lamprinos 2021 Kutztown University

Impact Of Whitetail Deer Overpopulation With Hunting On The Decline, Matthew J. Lamprinos

English Department: Research for Change - Wicked Problems in Our World

The whitetail deer is a key species for Pennsylvania’s forests, but their ecological balance has been disturbed by unregulated growth and urban sprawl. The deer population in Pennsylvania has exploded since the 1880’s causing a wide range of damage on the ecosystem, and humans. To reduce deer populations to sustainable levels, the Pennsylvania Game Commission relies heavily on hunters to dedicate time in the fall to go out and fill the tags the they issue. Hunter participation all around the world is decreasing for a variety of reasons. Fewer hunters out in the field causes revenue losses for ...


Using Modeling To Investigate Factors Driving Avian Diversity In Urban Ecosystems, Clay Bliznick 2021 Murray State University

Using Modeling To Investigate Factors Driving Avian Diversity In Urban Ecosystems, Clay Bliznick

Scholars Week

Anthropogenic influences have altered global landscapes considerably throughout the past two centuries, resulting in the decline of natural land cover types. Conversely, land cover types such as cropland and urban areas that are derived from human activities have experienced vast expansion. This landscape transition has serious implications for ecosystem services. To mitigate the loss of these services, it is necessary to maintain ecological integrity within these anthropogenically-influenced systems. Being able to support high biodiversity is an indicator of well-functioning ecosystems, thus quantifying biodiversity and assessing its contributing factors can be useful for developing management strategies in artificial environments. Our objective ...

Mining 30 Years Of Conifer Records At The Baker Arboretum, Monika Decker

Masters Theses & Specialist Projects

Only limited data had been published on the survivability of specimens within public gardens. This may be due to not enough data collected or how vast the plant selections are in the gardens. The Baker Arboretum has collected data by accessioning plant collections over a period of 30 years. The Baker Arboretum has its specimens GIS mapped on the 115-acre property for easy location and detection of the the woody ornamental plants. However, little research is available to understand which coniferous specimens have the best success in the garden. In this study, six separate binomial logistic regressions were run to ...


Small Mammals Killed In Discarded Bottles Along Roadsides In Central Nebraska, Owen J. Johnson, Keith Geluso 2021 NGPC

Small Mammals Killed In Discarded Bottles Along Roadsides In Central Nebraska, Owen J. Johnson, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Littered debris along roadways traps and kills small vertebrates. In Nebraska, at least 20 species of small mammals are small enough to enter openings of discarded bottles and cans. We surveyed roadsides for littered bottles and cans containing vertebrate remains in central parts of the state. We observed 459 bottles and 278 aluminum cans along 17.6 km of roadsides in Nebraska. Littered bottles contained 41 vertebrate remains representing nine taxa of small mammals. Glass bottles contained the majority of individuals, plastic bottles had a few individuals, and no vertebrate remains were detected in aluminum cans. Harvest mice (Reithrodontomys spp ...


A Comparison Of Intertidal Metazoan Biodiversity Between Previously Oiled Sheared And Intact Marsh Margins And Between Multiple Salinity Zones In The Coastal Marshes Of Louisiana, Patrick M. Rayle 2021 Louisiana State University and Agricultural and Mechanical College

A Comparison Of Intertidal Metazoan Biodiversity Between Previously Oiled Sheared And Intact Marsh Margins And Between Multiple Salinity Zones In The Coastal Marshes Of Louisiana, Patrick M. Rayle

LSU Master's Theses

Marshes in Louisiana are under threat from numerous natural and anthropogenic sources. A consequence of these threats are sheared marsh margins, which result from the impact of storm surge on previously oiled, weakened marsh. These conditions occurred in Louisiana marshes after Hurricane Isaac in 2012 followed the Deepwater Horizon oil spill in 2010, particularly in the shorelines surrounding Bay Jimmy. The second and third chapters of this thesis focus on the differences in biodiversity between the sheared and intact marsh margins in impacted sites in Bay Jimmy. Metabarcoding methods were used to determine community composition of the sediment within marsh ...

Vertebrate Impact On A Newly Deployed Shoreline Stabilization Project By Wildlife Camera Analysis, Julia Rifenberg, Jason Litwak, Rebecca Fillyaw

The Pegasus Review: UCF Undergraduate Research Journal

Living shoreline stabilization is a technique that utilizes plants and other natural elements to protect estuarine coasts. Research has provided minimal information about which vertebrate species utilize living shorelines post-deployment. For this project, ten wildlife cameras were placed along a living shoreline site in Canaveral National Seashore (CANA) to document which vertebrate species utilize the living shoreline and surrounding vegetation. This shoreline was stabilized with red mangroves (Rhizophora mangle) and eastern oyster (Crassostrea virginica) shell bags in June 2019. The cameras, activated by motion sensors, remained at the site for five days a month for seven months (September 2019 - March ...

Checklist Of The Inland Fishes Of Louisiana, Michael H. Doosey, Henry L. Bart Jr., Kyle R. Piller

Southeastern Fishes Council Proceedings

Since the publication of Freshwater Fishes of Louisiana (Douglas, 1974) and a revised checklist (Douglas and Jordan, 2002), much has changed regarding knowledge of inland fishes in the state. An updated reference on Louisiana’s inland and coastal fishes is long overdue. Inland waters of Louisiana are home to at least 224 species (165 primarily freshwater, 28 primarily marine, and 31 euryhaline or diadromous) in 45 families. This checklist is based on a compilation of fish collections records in Louisiana from 19 data providers in the Fishnet2 network (www.fishnet2.net). The checklist has grown because of descriptions of three ...


The Effects Of Urbanization On Plant Biodiversity In Southeastern Virginia, Tess Hardesty 2021 Old Dominion University

The Effects Of Urbanization On Plant Biodiversity In Southeastern Virginia, Tess Hardesty

Undergraduate Research Symposium

This research project investigated the impacts of urbanization on plant species biodiversity within Southeastern Virginia. The hypothesized results of this research were if there was an increase in urbanization, then plant diversity would decrease. Plant biodiversity can increase the decomposition rates, pollination success, and biomass production of the area. Decreasing in plant biodiversity can increase the spread of pathogens through plant populations and increase herbivore damage. There was data compiled from SERNEC herbarium records of four counties, Accomack, Northampton, Norfolk, and Virginia Beach. Virginia Beach had the largest population increase, which was considered the measurement for urbanization in this study ...

Protura (Arthropoda: Hexapoda) In Slovenian Caves, Loris Galli, Franc Janžekovič, Peter Kozel, Tone Novak

International Journal of Speleology

Protura is a small class of Hexapoda, generally poorly known, and rather scarce data on its occurrence in caves are scattered throughout literature on fauna in caves and in some papers on Protura. Although the cave-dwelling fauna is relatively well studied in Slovenia, published records on Protura are rare. In this paper, data on the occurrence and abundance of Protura in Slovenian caves are considered. Various statistical analyses were performed to compare caves with Protura to those without in 60 intensively monitored cavities to detect any differences in the selected environmental conditions. No significant difference was obtained. Samples collected from ...

Microhabitat Selection Of A Sicilian Subterranean Woodlouse And Its Implications For Cave Management, Giuseppe Nicolosi, Stefano Mammola, Salvatore Costanzo, Giorgio Sabella, Rosolino Cirrincione, Giovanni Signorello, Marco Isaia

International Journal of Speleology

Human activities in subterranean environments can affect different ecosystem components, including the resident fauna. Subterranean terrestrial invertebrates are particularly sensitive to environmental change, especially microclimatic variations. For instance, microclimate modifications caused by the visitors may directly affect local fauna in caves opened to the public. However, since numerous factors act synergistically in modulating the distribution and abundance of subterranean species, it remains challenging to differentiate the impact of human intervention from that of other factors. Therefore, evidence of the impact of tourism on cave invertebrate fauna remains scarce. Over a year and with approximately two visits a month, we investigated ...
