Spatial Responses of Adult Male White-tailed (Odocoileus Virginianus) Deer to Hunting Risk

Book Description
Movement responses of male white-tailed deer (Odocoileus virginianus) to hunting pressure vary across study systems and risk levels and may be confounded by breeding season. At the average levels of risk present on my study area (0.04 hunters/hectare/day) deer almost never altered behavior in response to hunter proximity. Home range characteristics did not predict risk exposure or risk management. Behavioral responses to levels of risk present in my study appear to be minimal, however bucks altered home range size and movements as the breeding season progressed. Most unconstrained movements occurred in early rut, with a 50% reduction during late and post rut. Encamped behaviors increased from pre to post rut, inversely with unconstrained behavior. Bucks 2 to 3 and 5 years old exhibited very little change in home range size, while 4 and 6+ year olds showed slight increases from pre to peak rut and decreases in late rut.
Spatial Ecology and Responses to a Controlled Hunt of Female White-tailed Deer in an Exurban Park

Book Description
White-tailed deer (Odocoileus virginianus) have adapted to and thrive in highly fragmented exurban habitats. Consequently, managers face new challenges dealing with deer population control in areas where traditional harvest regimes may no longer be practical or effective. Little is known about exurban deer ecology or about deer responses to controlled hunts, the latter of which is the most common method used for exurban deer population control. My study investigated spatial ecology and responses to controlled hunts of an exurban deer population residing on Fair Hill Natural Resource Management Area in Cecil County, Maryland. Fair Hill is an exurban park bordered by residential development and agricultural areas, and serves as a potential source for deer-human conflicts. From June 2004--January 2006, I collected approximately 37,000 telemetry locations on 66 collared female white-tailed deer to investigate seasonal home range sizes, home range fidelity, and hourly movement rates. Additionally, I monitored all deer before, during, and after a controlled shotgun hunt to investigate deer responses to hunting pressure. Average adaptive kernel home range sizes ranged from 8.1 ha--21.7 ha and 70.9 ha--144.5 ha among seasons at the 50% and 95% spatial scales, respectively. Average home range sizes followed a general increasing trend from the fawning through post-hunting season. Seasonal home range overlap differed by season at the 50% and 95% spatial scales, with the least overlap occurring between the post-hunting and fawning seasons (50%: x¯ = 19.4%, 95%: x¯ = 33.3%). Circadian activity rates varied among seasons, with dusk movements being greatest in all seasons. Average diurnal activity was greatest during the middle (1 Oct--30 Nov; x¯ = 65.7 m/hr) and late (1 Dec--31 Jan; x¯ = 67.8 m/hr) seasons and least during the post-hunting (1 Feb--30 Apr; x¯ = 46.2 m/hr). I found significant spatial and temporal responses of white-tailed deer to hunting pressure. Deer in non-refuge areas moved significantly more during (x¯ = 560.1 m) than either before (x¯ = 382.5 m) or after (x¯ = 417.5 m) the controlled hunts, whereas movement of deer in refuge areas did not change in response to the controlled hunt. Onstand and off-stand movements, defined as movements occurring while hunters were onstand or off-stand respectively, were greater in non-refuge (x¯ = 408.9 m and x¯ = 456.4 m) than refuge (x¯ = 261.2m and x¯ = 307.4 m) areas. Increased use of refuge areas in response to the controlled hunt resulted in a 20%--25% decrease in the percentage of deer available for harvest after the hunt. Consequently, only 50% of monitored deer remained available for harvest by the end of the hunt. My results suggest that to increase the efficacy of the current controlled hunt design at Fair Hill, managers should attempt to eliminate areas currently serving as refuge areas and consider changing hunt hours to include the dusk activity period.

Book Description
Scientists and conservationists are beginning to understand the importance of top carnivores to the health and integrity of fully functioning ecosystems. As burgeoning human populations continue to impinge on natural landscapes, the need for understanding carnivore populations and how we affect them is becoming increasingly acute.Desert Puma represents one of the most detailed assessments ever produced of the biology and ecology of a top carnivore. The husband-and-wife team of Kenneth Logan and Linda Sweanor set forth extensive data gathered from their ten-year field study of pumas in the Chihuahua Desert of New Mexico, also drawing on other reliable scientific data gathered throughout the puma's geographic range. Chapters examine: the evolutionary and modern history of pumas, their taxonomy, and physical description a detailed description and history of the study area in the Chihuahua Desert field techniques that were used in the research puma population dynamics and life history strategies the implications of puma behavior and social organization the relationships of pumas and their preyThe authors provide important new information about both the biology of pumas and their evolutionary ecology -- not only what pumas do, but why they do it. Logan and Sweanor explain how an understanding of puma evolutionary ecology can, and must, inform long-term conservation strategies. They end the book with their ideas regarding strategies for puma management and conservation, along with a consideration of the future of pumas and humans. Desert Puma makes a significant and original contribution to the science not only of pumas in desert ecosystems but of the role of top predators in all environments. It is an essential contribution to the bookshelf of any wildlife biologist or conservationist involved in large-scale land management or wildlife management.

Book Description
When a predator attacks, prey are faced with a series of 'if', 'when' and 'how' escape decisions – these critical questions are the foci of this book. Cooper and Blumstein bring together a balance of theory and empirical research to summarise over fifty years of scattered research and benchmark current thinking in the rapidly expanding literature on the behavioural ecology of escaping. The book consolidates current and new behaviour models with taxonomically divided empirical chapters that demonstrate the application of escape theory to different groups. The chapters integrate behaviour with physiology, genetics and evolution to lead the reader through the complex decisions faced by prey during a predator attack, examining how these decisions interact with life history and individual variation. The chapter on best practice field methodology and the ideas for future research presented throughout, ensure this volume is practical as well as informative.
