A Kansas City Founder "Proud Of His Position:" Race, Exploitation, And The Rise Of William Gilliss, Diane M. Euston Jan 2023

A Kansas City Founder "Proud Of His Position:" Race, Exploitation, And The Rise Of William Gilliss, Diane M. Euston

Graduate Theses/Dissertations

Americans are largely accustomed to the history of western expansion and enslavement by slaveholders. Questionable government policies led to the removal of Native American tribes further west. In Missouri, French Canadian traders moved to continue their business with them, and eventually, white settlement along the invisible border between Indian Territory and Missouri replaced indigenous peoples. William Gilliss, born in Maryland about 1797, is a prime example of an enterprising trader who, because of his reliance upon Native American tribes, followed his source of income west. His relationships with multiple Native American women resulted in at least three children. His relocation …

Measuring Microaggressions In The Advisor Advisee Relationship: Preliminary Scale Development, Samantha Lynn Bumgardaner Jan 2023

Measuring Microaggressions In The Advisor Advisee Relationship: Preliminary Scale Development, Samantha Lynn Bumgardaner

Graduate Theses/Dissertations

A number of survey instruments exist to measure microaggressions across various contexts and across numerous historically underrepresented groups. However, no such scale exists to assess microaggressions within the advisor-advisee relationship. The academic advisor-advisee relationship can make—or break—a student’s experience at a university, both personally and academically. Thus, microaggressions in the advisor-advisee relationship could impose numerous negative implications, both psychologically and academically. The goal of the present study aimed to develop a psychometrically sound scale to measure microaggressions in this association. Overall, findings from the present study offer preliminary support of a two-factor measure to assess microaggressions within the advisor-advisee relationship …

Riverine Fish Population Dynamics, Aaron P. Muehler Jan 2023

Riverine Fish Population Dynamics, Aaron P. Muehler

Graduate Theses/Dissertations

Dynamic rate functions (i.e., recruitment, growth, mortality) structure fish populations and are subject to latitudinal differences. These latitudinal differences are likely reflective of climatic variation and may result in spatially distinct populations that must be managed independently, especially in large systems such as the Upper Mississippi River system (UMRS). In order to successfully manage this system, an understanding of what drives these populations is required. The UMRS is useful for this investigation as it crosses 10° temperate latitude with widespread fish species found throughout. In this study, I investigated the synergistic relationship between latitude, vital rates, and abundance. Species were …

Quantitative Song Variety In Relation To Genotype In A Hybridizing Chickadee Population, Shelby Madison Palmer Jan 2023

Quantitative Song Variety In Relation To Genotype In A Hybridizing Chickadee Population, Shelby Madison Palmer

Graduate Theses/Dissertations

The Black-capped chickadee (Poecile atricapillus) and Carolina chickadee (P. carolinensis) are North American songbird species that hybridize in a narrow contact zone stretching latitudinally from New Jersey to Kansas, USA. The association between genetic ancestry and song type in this hybrid zone has been studied independently several times and found to be minimal or absent, likely due to the influence of cultural transmission on learned song in the oscine passerine clade to which the chickadees belong. Despite this, the song of both species remains remarkably distinct in allopatry, suggesting a genetic constraint on certain qualities of …

The Role Of Interspecific Competition In The Range Collapse Of A Songbird After Rapid Range Expansion, Zachary H. Vickers Jan 2023

The Role Of Interspecific Competition In The Range Collapse Of A Songbird After Rapid Range Expansion, Zachary H. Vickers

Graduate Theses/Dissertations

There is a wealth of evidence demonstrating interspecific competition in birds, but often this evidence is localized and may or may not entirely explain range dynamics over large geographic extents. Bewick’s Wrens (Thrymanes bewickii) and House Wrens (Troglodytes aedon) are small passerine birds of the family Troglodytidae. Previous experimental evidence has demonstrated that Bewick’s Wrens suffer from asymmetric interference competition from House Wrens in Kansas, and this evidence has been cited as the likely reason for the historically recent range collapse of the Bewick’s Wren. However, I argue that localized experimental evidence is insufficient to explain abundance trends over large …
