Phenology Of Asian Longhorned Beetle (Anoplophora Glabripennis, Coleoptera: Cerambycidae) In South Carolina, U.S.A., Lena Schmitt
Phenology Of Asian Longhorned Beetle (Anoplophora Glabripennis, Coleoptera: Cerambycidae) In South Carolina, U.S.A., Lena Schmitt
All Theses
A new population of the Asian longhorned beetle (Anoplophora glabripennis Motschulsky, hereafter ALB), an invasive species in the United States since 1996, was discovered in Charleston County, South Carolina in 2020. This population is the furthest south ALB has been found in North America and provides an opportunity to examine the phenology of this beetle in a novel climate. I collected 1009 eggs, larvae, pupae, and adult beetles from the federal quarantine zone in South Carolina and used larval head capsule widths to determine the rate of development and voltinism of ALB in South Carolina’s coastal climate. With this …
Investigating The Role Of Plant Traits And Interactions In Emergent Wetland Nutrient Removal, Andrew Ryan Sample
Investigating The Role Of Plant Traits And Interactions In Emergent Wetland Nutrient Removal, Andrew Ryan Sample
Theses and Dissertations
Increasing wetland restoration in the Lower Mississippi Alluvial Valley has been identified as a method to reduce nutrient loading in the Gulf of Mexico. Wetlands have historically been used to treat water through processes facilitated by wetland plants, and relatively few species and plant traits have been identified as important in carrying out these processes. This study focuses on some of those species and traits and aims to identify species differences and plant traits that may be important for wetland nutrient mitigation. Chapter I provides background information on nutrient pollution, wetland biogeochemical mechanisms for nutrient sequestration, and the focal species …
Exploring The Relationship Between Dreissenids And The Deep Chlorophyll Layer In The Laurentian Great Lakes, Lara E. Hargrave
Exploring The Relationship Between Dreissenids And The Deep Chlorophyll Layer In The Laurentian Great Lakes, Lara E. Hargrave
Great Lakes Center Masters Theses
In the Laurentian Great Lakes, two invasive bivalves Dreissena polymorpha and Dreissena rostriformis bugensis have induced a number of changes, including increased water transparency, alterations in nutrient cycling, decreased chlorophyll concentrations, and changes in phytoplankton community composition and structure. These changes are likely to have implications for the deep chlorophyll layer (DCL), a feature characterized by phototrophic organisms reaching abundance at light levels far below ideal for photosynthesis. Though the impacts of D. polymorpha and D. r. bugensis in the Great Lakes have been studied for at least the last three decades, little is known about how these ecosystem engineers …
Insight Into Eleutherodactylus Coqui Resilience And Anuran Hypoxia Tolerance Utilizing Pincho, Randy Ortiz
Insight Into Eleutherodactylus Coqui Resilience And Anuran Hypoxia Tolerance Utilizing Pincho, Randy Ortiz
Theses and Dissertations
The onset of high-throughput RNA-sequencing (RNA-seq) technology allowed research into transcriptomics to accelerate exponentially aided by the rapid advancement of bioinformatic pipelines. The Pincho workflow, my first research endeavor, is a transcriptomic workflow developed to create an avenue of high-quality reconstructions from RNA-seq data. High-quality reconstruction standards entail longer transcripts, more complete transcripts, and more raw data utilization. We have discovered an ideal trio of assemblers between transABySS, rnaSPAdes and TransLiG that would best reconstruct next-generation sequencing data according to these standards. We utilized Pincho to drive two distinct experiments: (1) exploring the genetic basis for the successful invasion of …
The Effects Of Anthropogenic Modification To The Landscape On Turtle Distribution And Health In South Dakota, Anna C. Kase
The Effects Of Anthropogenic Modification To The Landscape On Turtle Distribution And Health In South Dakota, Anna C. Kase
Dissertations and Theses
The Missouri River is a dynamic ecosystem that has been affected by anthropogenic modification and activity. The implementation of mainstem dams, reservoir formation, pollution, and non-native species invasions have greatly impacted this habitat and its constituents, particularly the false map turtle (Graptemys pseudogeographica). False map turtles are listed as a state threatened species in South Dakota and a focused large-scale assessment of their distribution and health has not been conducted since the 1960s. To address the gap in knowledge of how anthropogenic modifications to the Missouri River have impacted false map turtle distributions and health, the effect of a common …
Invasive Buckthorn Mapping: A Uav-Based Approach Utilizing Machine Learning, Gis, And Remote Sensing Techniques In The Upper Peninsula Of Michigan, Vikranth Madeppa
Invasive Buckthorn Mapping: A Uav-Based Approach Utilizing Machine Learning, Gis, And Remote Sensing Techniques In The Upper Peninsula Of Michigan, Vikranth Madeppa
Dissertations, Master's Theses and Master's Reports
An Invasive species is a species that is alien or non-native to the ecosystem which causes harm to economic, environmental, or human health (E.O. 13112 of Feb 3, 1999). Invasive species have posed a serious threat to ecosystems across the globe. These invasive species have impacts on the biodiversity and productivity of invaded forests. Remotely sensed data is a valuable resource for understanding and addressing issues related to invasive species. This study presents a novel approach for mapping the distribution of two invasive plant species, Common and Glossy Buckthorn, using unmanned aerial vehicles (UAVs), machine learning algorithms, geographic information systems …
Documenting Range Expansion Of Two Invasive Tick (Acari:Ixodidae) Species In Eastern South Dakota, Braden Wojahn
Documenting Range Expansion Of Two Invasive Tick (Acari:Ixodidae) Species In Eastern South Dakota, Braden Wojahn
Dissertations and Theses
This project documents the expanded zoogeographic ranges of the blacklegged tick (Ixodes scapularis) and lone star tick (Amblyomma americanum) within eastern South Dakota. Ticks are important when considering a “One Health” approach, as many species are competent vectors of zoonotic pathogens causing human diseases and conditions such as Lyme disease, tularemia, rickettsia, and alpha gal syndrome. The research involved constitutes two steps. First, tick surveillance was conducted in eastern counties of South Dakota, spanning March 2021 through August 2022. Surveillance took place along edge habitat at recreation areas, state and public parks, wildlife management areas and refuges, and other natural …
The Effect Of Alkalinity On Lampricide Effectiveness And Gill Physiology In Invasive Sea Lamprey (Petromyzon Marinus), Alexandre J. Walsh
The Effect Of Alkalinity On Lampricide Effectiveness And Gill Physiology In Invasive Sea Lamprey (Petromyzon Marinus), Alexandre J. Walsh
Theses and Dissertations (Comprehensive)
The pesticides, 3-trifluoromethyl-4-nitrophenol (TFM) and niclosamide are used to control populations of invasive sea lamprey (Petromyzon marinus) in the Laurentian Great Lakes of North America. Added to streams infested with larval sea lamprey, the effectiveness of these pesticides, commonly called lampricides, are strongly influenced by water pH, with greater toxicity for both TFM and niclosamide in lower pH than higher pH water. However, the TFM and niclosamide sensitivity of sea lamprey are also greater in poorly buffered, low alkalinity water than in high alkalinity water but it is unclear why. One goal of my thesis was to propose …
