Host Manipulation by Parasites by David P. Hughes,Jacques Brodeur,Frédéric Thomas Pdf
Parasites that manipulate the behaviour of their hosts represent striking examples of adaptation by natural selection. This text provides an authoritative review of host manipulation by parasites that assesses developments in the field and lays out a framework for future research.
Host Manipulations by Parasites and Viruses by Heinz Mehlhorn Pdf
This edited volume focuses on parasite-host relationships and the behavioral changes parasites may trigger in their hosts. Parasites have developed strategies which enhance their chances to find a host to survive inside its body and to become most easily transmitted to one another. Many of these parasites influence the host’s behavior by various mechanisms, so that the rate of their transmissions to further hosts becomes considerably enhanced in comparison to that of non-influenced specimens of the same host species. A broad number of recent studies elucidate more and more examples in an extreme spectrum of host-parasite relationships, where successful transmission and /or survival of a parasite inside a host is based on parasite-derived behavioral manipulations of the hosts. In the literature, an increasing numbers of papers appear which prove that these behavioral alterations are based on complicated psychoimmunologic, neuropharmacologic and genomically steered mechanisms. Researchers working in parasitology or behavioral sciences will find this work thought-provoking, instructive and informative.
Parasites and the Behavior of Animals by Janice Moore Pdf
When a parasite invades an ant, does the ant behave like other ants? Maybe not-and if it doesn't, who, if anyone, benefits from the altered behaviors? The parasite? The ant? Parasites and the Behavior of Animals shows that parasite-induced behavioral alterations are more common than we might realize, and it places these alterations in an evolutionary and ecological context. Emphasizing eukaryotic parasites, the book examines the adaptive nature of behavioral changes associated with parasitism, exploring the effects of these changes on parasite transmission, parasite avoidance, and the fitness of both host and parasite. The behavioral changes and their effects are not always straightforward. To the extent that virulence, for instance, is linked to parasite transmission, the evolutionary interests of parasite and host will diverge, and the current winner of the contest to maximize reproductive rates may not be clear, or, for that matter, inevitable. Nonetheless, by affecting susceptibility, host/parasite lifespan and fecundity, and transmission itself, host behavior influences parameters that are basic to our comprehension of how parasites invade host populations, and fundamentally, how parasites evolve. Such an understanding is important for a wide range of scientists, from ecologists and parasitologists to evolutionary, conservation and behavioral biologists: The behavioral alterations that parasites induce can subtly and profoundly affect the distribution and abundance of animals.
Ecology and Evolution of Parasitism by Frédéric Thomas,Jean-François Guégan,François Renaud Pdf
Biologists are increasingly aware of the universal significance of parasites to the study of ecology and evolution where they have become a powerful model system. This book provides a summary of the issues involved as well as an overview of the possibilities offered by this research topic including the practical applications in disease prevention.
A Checklist of Host-Parasite Interactions of the Order Crocodylia by Marisa Tellez Pdf
Records of parasitism in crocodilians date back to the early 1800s, distributed among various types of published and unpublished materials. Analyzing parasite-host specificity, geographic distribution, and taxonomy can provide otherwise cryptic details about crocodilian ecology and evolution, as well as their local food web dynamics. This information is critical for improved conservation tactics for both crocodilians and their habitat. As climate change, anthropogenic conflict, and environmental pollution endanger crocodilian ecosystems, there is a need for organized information on crocodile, alligator, caiman, and gharial infectious diseases. This volume meets this need by delivering the first checklist of crocodilians and their parasites for researchers and scholars in biology, herpetology, and ecology in order to further the knowledge and study of crocodilian-parasite dynamics and improve our understanding of human impacts on ecosystems.

Host or Parasite? by Allen J. Romano,John Marincola Pdf
Building upon the explosion of recent work on mythography, contributions to this volume direct attention to less frequently explored questions of how ancient poets, historians, and philosophers themselves adopted and adapted the work of mythographers. Study of the way that mythographers and their contemporaries take on positions of, alternately, “host” or “parasite” in relation to the other exposes the richness mythographic practice and the roles that mythographers played in the evolving Greco-Roman discourse of myth. From, among others, the seeds of mythographic discourse in Pindar and Plato, to the mythography of the Peripatics, the in-between mythography of Diodorus Siculus, and the “mythographic topography” of Pausanias, this volume invites a reappraisal of the role that mythography played at every stage of Greek thought about myth. Through contributions that explore both mythographers’ distinctive style of studying myth to other contributions that focus primarily on the how and why of non-mythographers’ use of mythographic techniques, what emerges is a picture of mythography that broadens our conception of mythography while at the same time inviting scholars to seek out more such echoes of mythographic discourse in the work of poets, historians, philosophers at large.
The Biogeography of Host-Parasite Interactions by Serge Morand,Boris R. Krasnov Pdf
Biogeography has renewed its concepts and methods following important recent advances in phylogenetics, macroecology, and geographic information systems. In parallel, the evolutionary ecology of host-parasite interactions has attracted the interests of numerous studies dealing with life-history traits evolution, community ecology, and evolutionary epidemiology. The Biogeography of Host-Parasite Interactions is the first book to integrate these two fields, using examples from a variety of host-parasite associations in various regions, and across both ecological and evolutionary timescales. Besides a strong theoretical component, there is a bias towards applications, specifically in the fields of historical biogeography, palaeontology, phylogeography, landscape epidemiology, invasion biology, conservation biology, human evolution, and health ecology. A particular emphasis concerns emerging and re-emerging infectious diseases linked to global changes.
Host-Parasite Interactions by Gert Flik,Geert Wiegertjes Pdf
This volume summarizes current research into the physiology and molecular biology of host-parasite interactions. Brought together by leading international experts in the field, the first section outlines fundamental processes, followed by specific examples in the concluding section. Covering a wide range of organisms, Host-Parasite Interactions is essential reading for researchers in the field.
The U.S. republic founded in 1787 bears no resemblance to the anti-democratic police state that has declared war on its citizens, and provokes needless wars in the Middle East at the behest of Israel. At the center of it all is the parasitic control of the Israel Lobby on the U.S. government. Beginning with the presidency of Harry Truman and continuing into the Trump administration, The Host and The Parasite shows how The Lobby, evangelical Christians and neo-conservatives rode to power, especially after 1980, and proceeded to turn the United States into Israel's willing executioner.
Recent ideas and experimental studies suggest that the relationship between parasitism and host behaviour has been a powerful shaping force in the evolution not only of behaviour patterns themselves but, through them, of morphology and population and community dynamics. This book brings together recent work across the disciplines of parasitology an
Host-parasite Evolution by Dale H. Clayton,Janice Moore Pdf
This is a question-oriented volume with a solid organismal foundation that will help to bridge the gap between evolutionary ecologists and parasitologists. A range of experts have written chapters that review general concepts and provide a detailed survey of the parasites of a major group of hosts. The book concludes with extensive reviews of methods used to study bird parasites. It is a novel and valuable tool for anyone interested in understanding host-parasite interactions, particularly from an evolutionary perspective.
Parasite Communities: Patterns and Processes by Gerald W. Esch Pdf
We first discussed the possibility of organizing a symposium on helminth communities in June, 1986. At that time, we were engaged in writing a joint paper on potential structuring mechanisms in helminth communities; we disagreed on a number of issues. We felt the reason for such debate was because the discipline was in a great state of flux, with many new concepts and approaches being introduced with increasing frequency. After consider able discussion about the need, scope and the inevitable limitations of such a symposium, we decided that the time was ripe to bring other ecologists, engaged in similar research, face-to-face. There were many individuals from whom to choose; we selected those who were actively publishing on helminth communities or those who had expertise in areas which we felt were particularly appropriate. We compiled a list of potential participants, contacted them and received unanimous support to organize such a symposium. Our intent was to cover several broad areas, fully recognizing that breadth negates depth (at least with a publisher's limitation on the number of pages). We felt it important to consider patterns amongst different kinds of hosts because this is where we had disagreed among ourselves.
The Rasputin Effect: When Commensals and Symbionts Become Parasitic by Christon J. Hurst Pdf
This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host. It examines the triggering events which can factor into these changes, such as reduction in the host’s capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality. The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host’s protective natural microflora. The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts.

In Parasitism, Claude Combes explores the fascinating adaptations parasites have developed through their intimate interactions with their hosts. He begins with the biology of parasites—their life cycles, habitats, and different types of associations with their hosts. Next he discusses genetic interactions between hosts and parasites, and he ends with a section on the community ecology of parasites and their role in the evolution of their hosts. Throughout the book Combes enlivens his discussion with a wealth of concrete examples of host-parasite interactions.
