Flea And Louse Infestations Of Cotton Rats (Sigmodon Hispidus) In The Southeastern United States, Alena E. Aviles Jan 2009

Flea And Louse Infestations Of Cotton Rats (Sigmodon Hispidus) In The Southeastern United States, Alena E. Aviles

Electronic Theses and Dissertations

Ectoparasites were collected from cotton rats (Sigmodon hispidus) in 20 sites in the Southeastern United States (FL, GA, MS, NC and SC). Prevalence and mean intensity of parasitism by sucking lice (Anoplura) and fleas (Siphonaptera) of cotton rats were recorded at all sites. The geographical distribution of S. hispidus and its main louse and flea ectoparasites range from the neotropical region to the southeastern USA. It was hypothesized that the abundance of the cotton rat associated louse (Hoplopleura hirsuta) and flea (Polygenis gwyni) would increase the further south and closer to the distribution centers of each of these ectoparasite species. …


Seasonal Habitat Use Of The Florida Manatee (Trichecus Manatus Latirostris) In The Crystal River Natural Refuge With Regards To Natural And Anthropogenic Factors, Ryan Willard Berger May 2007

Seasonal Habitat Use Of The Florida Manatee (Trichecus Manatus Latirostris) In The Crystal River Natural Refuge With Regards To Natural And Anthropogenic Factors, Ryan Willard Berger

Electronic Theses and Dissertations

Natural and anthropogenic factors work together to influence species habitat use. Kings Bay in Crystal River, Florida serves as critical habitat for the Florida manatee, but is also used extensively by humans. This study documented the seasonal dispersion and behavioral patterns of manatees in Kings Bay with regards to natural and anthropogenic factors from May 2005-June 2006. Survey stations were established across the bay and the number of manatees, people in the water, and boats were counted. The behavioral patterns of four major states were recorded using focal animal observations. During the winter, manatees aggregated in areas containing both springs …


Playground For The Imagination, B. Darlene Miller May 2006

Playground For The Imagination, B. Darlene Miller

Electronic Theses and Dissertations

Over the past years, my work has been based on a desire to depict the spiritual and physiological interdependence humans have with the wetland ecosystem. As I examine the shapes of trees and their roots through rubbings, paintings, and sculpture, I sought to express this interaction between humans and nature. My artwork metamorphosed from the traditionally separated forms of painting and sculpture into an environment. The transformation of natural materials into manufactured products led me to cultivate a deeper understanding of ecology, where humans are participants in the natural process of the life cycle. Nature becomes the primary subject and …


Genetic Variation Within And Among Populations Of Florida Burrowing Owls (Athene Cunicularia Floridana), Wendy T. Denton Jan 1998

Genetic Variation Within And Among Populations Of Florida Burrowing Owls (Athene Cunicularia Floridana), Wendy T. Denton

Legacy ETDs

This study employed DNA Polymerase Chain Reaction (PGR) and Single-Stranded Conformation Polymorphisms (SSCP) on a mitochondrial control region target to assess population structure and possible gene flow in the Florida Burrowing Owl (Athene cunicularia floridana), a Florida Species of Special Concern. Although widespread in Florida, Burrowing Owls occur at low densities in semi-isolated populations that are susceptible to extirpation from human development and the demographic consequences of small population size. To better manage these populations, there is a need for data on the population genetic structure of the Florida Burrowing Owl. Therefore, I acquired DNA from Burrowing Owls …
