Analysis Of The Population Structure And Migrationhabits Of The Northern Leopard Frog (Lithobates Pipiens) At Midewin National Tallgrass Prairie, Gretchen A. Brinkman
Analysis Of The Population Structure And Migrationhabits Of The Northern Leopard Frog (Lithobates Pipiens) At Midewin National Tallgrass Prairie, Gretchen A. Brinkman
ELAIA
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 of migration …

Massive amphibian declines of recent years have pushed researchers to pursue population genetics surveys and to assess the status of these essential components of many ecosystems. The Northern Leopard Frog (Lithobates pipiens) has been continuously experiencing population declines across the continental United States due to a combination of habitat loss and environmental change. Midewin National Tallgrass Prairie houses a considerable portion of Northern Leopard Frog (L. pipiens) in Illinois, and within this location, two creeks provide ideal conditions to support these animals.

The Role Of Endangered Oak (Quercus Spp.) Savanna Characteristics In Supporting Red-Headed Woodpecker (Melanerpes Erythrocephalus L.) Populations, Kimberly J. Zralka
The Role Of Endangered Oak (Quercus Spp.) Savanna Characteristics In Supporting Red-Headed Woodpecker (Melanerpes Erythrocephalus L.) Populations, Kimberly J. Zralka
Honors Program Projects
Declines in animal populations worldwide are of critical conservation concern. However, without an understanding of optimal habitat preference, it is often difficult to determine what factors are driving these losses. Red-headed woodpecker (Melanerpes erythrocephalus L.) populations have declined by over 70% in the last 50 years, yet in some areas the birds seem to maintain stable populations. The aim of this study was to empirically test the effects of various habitat factors on red-headed woodpecker presence and abundance in both the summer and winter seasons. As oak acorns are a critical food source for this bird, we were particularly …
The Effects Of Native And Domestic Grazers On The Health Of Bumble Bee (Bombus Spp.) Populations In A Historical Tallgrass Prairie Ecosystem, Mckenna Conforti
The Effects Of Native And Domestic Grazers On The Health Of Bumble Bee (Bombus Spp.) Populations In A Historical Tallgrass Prairie Ecosystem, Mckenna Conforti
Honors Program Projects
Bumble bees (Bombus spp.) play an important role in the pollination of ecologically and economically significant plants worldwide. In recent years, bumble bee populations have suffered decline throughout North America, particularly in the Midwest. Many factors likely contribute to this decline, including the use of pesticides, disease, and habitat loss. Although cattle grazing space is a common use for Midwestern grassland, a comparison had not been made between the capacity of cattle pasture to support bumble bee communities with the capacity of tallgrass prairie, a habitat thought to be optimal for requisite floral resources. Additionally, the reintroduction of bison …

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 …
