Analysis Of The Population Structure And Migration Habits Of The Northern Leopard Frog (Lithobates Pipiens) At Midewin National Tallgrass Prairie, Gretchen A. Brinkman
Analysis Of The Population Structure And Migration Habits Of The Northern Leopard Frog (Lithobates Pipiens) At Midewin National Tallgrass Prairie, Gretchen A. Brinkman
Honors Program Projects
Massive amphibian declines of recent years have pushed researchers to pursue population genetics surveys and assess the status of these essential components of many ecosystems. The Northern Leopard Frog (Lithobates pipiens) has continuously experienced population declines across the continental United States due to a combination of habitat losses and environmental changes. Midewin National Tallgrass Prairie houses a considerable portion of L. pipiens in Illinois, and the two creek watersheds studied within this location provide ideal conditions to support these animals. Because this prairie restoration project is a relatively recent development, further assessments regarding the population structure and degree …
Relationships Between Elements Of Leslie Matrices And Future Growth Of The Population, Lorisha Lynn Riley
Relationships Between Elements Of Leslie Matrices And Future Growth Of The Population, Lorisha Lynn Riley
Honors Program Projects
Leslie matrices have been used for years to model and predict the growth of animal populations. Recently, general rules have been applied that can relatively easily determine whether an animal population will grow or decline. My mentor, Dr. Justin Brown and I examine, more specifically, whether there are relationships between certain elements of a population and the dominant eigenvalue, which determines growth. Not only do we consider the general 3x3 Leslie matrix, but also we looked into modified versions for incomplete data and migration models of Leslie matrices. We successfully found several connections within these cases; however, there is much …
