Book Description
Supplemental feeding of deer is a common management action. However, concentrating animals, as feeding does, is known to promote the transmission of disease. We examined how feeding alters three sources of disease: aflatoxins, gastrointestinal parasites, and ticks. To do this, we paired 79 feeder sites throughout Mississippi with ecologically-equivalent sites without feeders. Wildlife visitation increased at feeders compared to sites without feeders. For aflatoxins, we sampled during the summer and hunting season and found low prevalence and levels in feeders and bagged/bulk feed. The greater concern was environmental exposure to aflatoxins. All corn piles exposed to environmental contamination in July contained toxic levels of aflatoxins after eight days. The environmental load of gastrointestinal parasites was elevated for coccidia (4x) and strongylids (3x). Finally, feeding reduced the number of ticks at feeder sites, but did not alter the prevalence of tick-borne diseases within captured ticks compared to sites without feeders.

Book Description
White-tailed deer (Odocoileous virginianus ) are an important game animal and provide intrinsic value to many people. However, disease has become of great concern within white-tailed deer populations. Frequency of contract drives the establishment and spread of infectious diseases among susceptible hosts. Supplemental feed provided to increase white-tailed deer survival or create hunting opportunities, as well as bait stations to aid in capture of deer, may increase contact opportunities and disease transfer. The author's objective was to quantify the effects of bait sites on indirect contact between deer. The author examined data from global positioning system (GPS) collars placed on 27 deer near Carbondale, Illinois, USA, from 2002 to 2005. Location data from GPS collars were used to ensure that the author quantified contacts between deer in separate social groups, based on the volume of intersection of their spatial utilization distributions and correlation of movements. Understanding the spatial distribution of white-tailed deer is important to implement effective disease and population management within localized areas. The objective of this study was to measure the home-range fidelity of female deer in an exurban deer herd in southern Illinois.

Book Description
Easily the most common of America’s large wildlife species, white-tailed deer are often referred to as "overabundant." But when does a species cross the threshold from common to overpopulated? This question has been the focus of debate in recent years among hunters, animal rights activists, and biologists. William McShea and his colleagues explore every aspect of the issue in The Science of Overabundance. Are there really too many deer? Do efforts to control deer populations really work? What broader lessons can we learn from efforts to understand deer population dynamics? Through twenty-three chapters, the editors and contributors dismiss widely held lore and provide solid information on this perplexing problem.

Book Description
Bovine tuberculosis (bTB) is a significant zoonotic pathogen with a global distribution, and a considerable economic impact. It has a notoriously complex epidemiology, varying by affected region and often involving multiple-host species. Here we present an international collection of papers that address both national and international factors impacting on the control of bovine tuberculosis. We hope this Research Topic will provide a forum which may generate a greater understanding of the disease in a wider context, and inform future eradication efforts through the design of more effective interventions.

Book Description
Infections with recognized and putative species of the genus pestivirus are not host-specific and are documented in many wildlife species. The study of pestivirus infections in wildlife species is important both to eradication programs and programs for maintaining the health and well-being of wildlife populations. Free-ranging wildlife species may act as reservoirs for pestiviruses that infect domestic species. For this reason, eradication efforts for classical swine fever virus include control of the virus in wild boar populations. The contribution of free-ranging species to the circulation of BVDV1, BVDV2, and BDV is less well understood. While substantial damage due to pestivirus infections has been demonstrated in a few specific wildlife populations, the impact of pestiviral infections on the well-being of most captive and free-ranging wildlife populations is largely unknown. The research topics summarizes our current understanding of pestiviral infections in wildlife and discusses the challenges in understanding and mediating their impact on captive and free ranging wildlife species.

Book Description
This volume offers an overview of the processes of zoonotic viral emergence, the intricacies of host/virus interactions, and the role of biological transitions and modifying factors. The themes introduced here are amplified and explored in detail by the contributing authors, who explore the mechanisms and unique circumstances by which evolution, biology, history, and current context have contrived to drive the emergence of different zoonotic agents by a series of related events.

Book Description
Encyclopedia of Agriculture and Food Systems, Second Edition, Five Volume Set addresses important issues by examining topics of global agriculture and food systems that are key to understanding the challenges we face. Questions it addresses include: Will we be able to produce enough food to meet the increasing dietary needs and wants of the additional two billion people expected to inhabit our planet by 2050? Will we be able to meet the need for so much more food while simultaneously reducing adverse environmental effects of today’s agriculture practices? Will we be able to produce the additional food using less land and water than we use now? These are among the most important challenges that face our planet in the coming decades. The broad themes of food systems and people, agriculture and the environment, the science of agriculture, agricultural products, and agricultural production systems are covered in more than 200 separate chapters of this work. The book provides information that serves as the foundation for discussion of the food and environment challenges of the world. An international group of highly respected authors addresses these issues from a global perspective and provides the background, references, and linkages for further exploration of each of topics of this comprehensive work. Addresses important challenges of sustainability and efficiency from a global perspective. Takes a detailed look at the important issues affecting the agricultural and food industries today. Full colour throughout.

Book Description
Surveillance, early detection, control and eradication of notifiable animal diseases is of critical importance for countries in order to maintain or improve their animal health status. This requires the collaboration of all stakeholders involved including animal health authorities, livestock industry and veterinary research institutions among others. Prevention, control and eradication programs must take into account the characteristics of the host (including potential reservoirs), the pathogen (transmissibility, virulence…) and the environment (temperature, animal density…) but also the socio-economic context in which they have to be implemented (highly influenced by funding availability), while at the same time guaranteeing compliance with international trade regulations. This has led to the adoption of a wide range of approaches to address the risk posed by specific pathogens in different countries, and at the same time similar strategies have yielded very different results in different regions. This Research Topic includes a variety of manuscripts focusing on different aspects of surveillance, control and eradication of diseases of critical importance for livestock, including cattle, swine and wildlife, in an attempt to provide an overview of the current situation in different countries.
