Drivers Of White-Tailed Deer (Odocoileus Virginianus) Behavior, Survival, And Population Growth In The Piedmont Of South Carolina, Michael Muthersbaugh
Drivers Of White-Tailed Deer (Odocoileus Virginianus) Behavior, Survival, And Population Growth In The Piedmont Of South Carolina, Michael Muthersbaugh
All Dissertations
Prey species adjust behaviors in response to various stimuli, responding to both top-down and bottom-up pressures. Large herbivores must attempt to avoid predation either through adjusting behaviors or seeking spatial or temporal refugia, which can scale up to influence individual fitness and ultimately population dynamics. Specifically, predation risk has a great potential to influence ungulate populations by impacting behaviors and survival. Our objective was to quantify ungulate behavioral and population response to a regionally important predator through a case study – white-tailed deer (Odocoileus virginianus) responses to coyotes (Canis latrans) on private lands in the Piedmont …
Evaluation Of Grazing Techniques As A Nutrition Source For Horses In A Pasture Environment, Brittany Perron
Evaluation Of Grazing Techniques As A Nutrition Source For Horses In A Pasture Environment, Brittany Perron
All Dissertations
Horses require daily access to forage in order to support their gastrointestinal tract function as well as natural grazing behaviors. Well-managed pasture provides horses with a consistent forage source and diminishes health risks such as colic, ulcers and stereotypies. However, equine grazing behaviors are more intense than other livestock and may be detrimental to plant and soil health. A grazing management technique specifically for horses is necessary to prevent both health and environmental issues. The following dissertation explores both the movement of required maintenance elements, such as feed, shelter, and water, as well as the manipulation of feeding frequency and …
Biology And Control Of The Bed Bug Cimex Lectularius L., Kevin Hinson
Biology And Control Of The Bed Bug Cimex Lectularius L., Kevin Hinson
All Dissertations
After vanishing from the public eye for more than 50 years, bed bugs have resurged to become one of the most widely discussed and heavily researched insect pests in the westernized world. Our inability to prevent and successfully treat infestations has been the driving force behind this wave of research. I addressed gaps in our understanding of bed bugs by examining behavioral and life history characteristics, as well as insecticide application responses. I showed that natural-based products are generally ineffective against bed bugs, particularly when used as a residual treatment. I also found that bed bugs may be killed through …
The Role Of Behavioral Temperaments On The Ecology Of The Caribbean Reef Octopus, Octopus Briareus, Timothy Jordan
The Role Of Behavioral Temperaments On The Ecology Of The Caribbean Reef Octopus, Octopus Briareus, Timothy Jordan
All Theses
Traditional studies of predator-prey interactions have primarily focused on direct consumption as the most important effect on prey. Recent studies, however, have illustrated that nonlethal, risk effects may have an even greater impact. In this study, I evaluated the role of direct consumption and risk effects of the Caribbean reef octopus, Octopus briareus, on multiple species of crab and spiny lobster prey in Florida Bay, Florida. I conducted 13 monthly censuses of 8 nearshore field sites and observed the density and distribution of octopuses, crabs and lobsters. I found a significant negative correlation between the density of octopus predators and …
