Transcriptional Regulation Of Duox-Dependent Reactive Oxygen Species Production Against Bacterial Infection In The Gut Of Cat Fleas (Ctenocephalides Felis)., Ryne W. Maness Jan 2021

Transcriptional Regulation Of Duox-Dependent Reactive Oxygen Species Production Against Bacterial Infection In The Gut Of Cat Fleas (Ctenocephalides Felis)., Ryne W. Maness

College of Graduate Studies: Theses & Dissertations

Fleas (Order Siphonaptera) are opportunistic blood feeders that parasitize a wide variety of mammals and birds. They also transmit bacterial pathogens that cause diseases in humans (e.g., murine typhus, flea-borne spotted fever, cat scratch disease, and plague). Because they acquire infectious pathogens while blood feeding, the flea gut is considered to be the initial site of infection. While immune responses have been well documented in other disease vectors, few studies have identified the immune mechanisms involved in defense of the flea gut. In other hematophagous insects, the synthesis of reactive oxygen species (ROS) is the immediate immune defense mechanism against …

Novel Quantification And Localization Of Water And Solute Transporters In The Tissues Of The Spiney Dogfish (Squalus Acanthias), Tolulope B. Ojo Jan 2021

Novel Quantification And Localization Of Water And Solute Transporters In The Tissues Of The Spiney Dogfish (Squalus Acanthias), Tolulope B. Ojo

College of Graduate Studies: Theses & Dissertations

The dogfish, Squalus acanthias is a marine cartilaginous elasmobranch found in the North Atlantic and Pacific oceans. Dogfish synthesize and excrete urea as a product of nitrogen metabolism. They also convert ammonia into urea and retain this urea, such that their plasma is isosmotic or slightly hyperosmotic to the surrounding seawater. To facilitate the regulation of body fluid and to maintain ionic concentrations and osmotic pressure, Dogfish use ion and solute transporters (e.g., NCC, UT-1) and aquaporin water channel proteins. Studies have identified some of the aquaporin genes in the elasmobranch genome, but their functions are mostly uncharacterized. Recent transcriptomic …

Free-Roaming Cat Abundance Across A Habitat Gradient, Rachel E. Bird Jan 2021

Free-Roaming Cat Abundance Across A Habitat Gradient, Rachel E. Bird

College of Graduate Studies: Theses & Dissertations

There are an estimated 172 million owned and feral cats in the United States, and wildlife enthusiasts and cat owners are often at odds over how best to manage free-roaming cats. Management is needed because of the documented impacts of free-ranging cats on wildlife. Targeting these management efforts, however, is hampered by an imperfect understanding of cat distribution in the landscape. My study used game cameras and capture-recapture sampling to estimate abundance of free-roaming cats across a habitat gradient in Bulloch County, Georgia, USA. In all, I detected cats at 51% (25/49) sites with a mean of 2.1 cats per …

Sexual Dimorphism Of Thermal Preference In Florida Scrub Lizards (Sceloporus Woodi) And Predicting Response To Climate Change In Two Rare Habitats, Sidney E. Anderson Jan 2021

Sexual Dimorphism Of Thermal Preference In Florida Scrub Lizards (Sceloporus Woodi) And Predicting Response To Climate Change In Two Rare Habitats, Sidney E. Anderson

College of Graduate Studies: Theses & Dissertations

The Florida Scrub Lizard (Sceloporus woodi) is endemic to Florida, where it inhabits fragments of xeric sandhill uplands including endangered long-leaf pine and sand pine scrub habitats. Lizards depend on a predictable range of temperatures to maximize their growth and productivity, and to do so, they shuttle among various thermal micro-environments. Thus, the spatial distribution of temperatures in the habitat is important. Habitats dominated by either high or low extremes of an organism’s preference are energetically costly and dangerous (less optimal), especially to gravid females. This study examines thermal preference of a near-threatened species that also inhabits increasingly rare habitats. …

Disease Prevalence And The Population Genetic Structure Of Crassostrea Virginica Along The Georgia Coast, Sarah Batchelor

College of Graduate Studies: Theses & Dissertations

The Eastern Oyster, Crassostrea virginica, is an ecologically important species that plays a role in protecting shorelines, water filtration, and providing habitat and food for various fish species. Perkinsus marinus and Haplosporidium nesloni are two pathogens currently affecting oyster populations. These pathogens have both been documented as causes of mass mortality events along the East coast. They greatly diminish the health of oysters, resulting in the degradation of oyster tissue, reduction in growth and reproductive ability, and may cause death. In this study, wild oysters were collected from eleven locations along the Georgia coast to investigate the presence, intensity, …

The Effects Of Habitat Fragmentation On Avian Mobbing Behavior, Jada T. Daniels Jan 2021

The Effects Of Habitat Fragmentation On Avian Mobbing Behavior, Jada T. Daniels

College of Graduate Studies: Theses & Dissertations

Habitat fragmentation has negative effects on bird species diversity, as well as reproductive success of some species. However, there is little comparative information on the effect it may have on bird behavior. For example, small forest fragments are likely to have fewer bird species and individuals. This may limit the success of mobbing as an antipredator behavior because mobbing success depends on recruiting other birds to the group. This possibility has never been tested. The objective of my study is to quantify the effects of forest size on mobbing behavior in forest-dwelling birds. Mobbing behavior was elicited in 100 randomly …

Falciparum Gametocyte Carriage Among School Children In Mbita, Western Kenya And Assessment Of The Association Between Gametocyte Density, Multiplicity Of Infection And Mosquito Infection Prevalence., Victor A. Mobegi, Jeremy K. Herren, Abdoulie O. Touray, Fred Wamunyokoli, Hellen Butungi

All Peer-Reviewed Publications

Background: Asymptomatic Plasmodium falciparum gametocyte carriers are reservoirs for sustaining transmission in malaria endemic regions. Gametocyte presence in the host peripheral blood is a predictor of capacity to transmit malaria. However, it does not always directly translate to mosquito infectivity. Factors that affect mosquito infectivity include, gametocyte sex-ratio and density, multiplicity of infection (MOI), and host and vector anti-parasite immunity. We assess the prevalence of gametocyte carriage and some of its associated risk factors among asymptomatic schoolchildren in Western Kenya and to further analyse the association between gametocyte density, multiplicity of infection (MOI) and mosquito infection prevalence. Methods: P. falciparum …

Ceratitis FAR is an African species complex comprising insect pests of great economic interest and obscure species limits. Here, we report the mitochondrial genomes of two members of the FAR complex, namely Ceratitis rosa and the recently characterized Ceratitis quilicii. A phylogenetic analysis based on PCGs of available Tephritidae mitogenomes is presented. The current mitochondrial sequences from the FAR complex could contribute toward the resolution of phylogenetic relationships and species limits within this taxonomically challenging group, which is also an important issue for the development of environment-friendly and species-specific control methods, such as the sterile insect technique (SIT).

Turkish Journal of Veterinary & Animal Sciences

Ocular sonography and echobiometry was performed in local nondescript sheep (N = 36) of different age group and in adult corriedale (N = 60), crossbred Fec B (N = 48), and Poll Dorset cross breed sheep (N = 48). Cornea, anterior, posterior lens capsule, and retinal rim appeared hyperechoic whereas aqueous, vitreous humor, and nucleus of lens were anechoic. Significant increase (P < 0.05) in all the echobiometric measurement of the ocular distance except central corneal thickness and retinal rim thickness was recorded in the older animals (2 year old) compared to values recorded in animals at one month of age in local nondescript sheep. Significant differences (P < 0.05) in few recorded ocular biometric measurements were also noticed among different sheep breeds. However, the difference in the various ocular biometric measurements between the right and left eyes was nonsignificant. The results of this study provide the base line information regarding the ocular echobiometry in sheep that are relevant to comparative ocular anatomy and can be useful for ultrasonographic evaluation of different ocular affections in sheep.
