This book represents a cutting-edge contribution giving an all-around perspective of eco-immunology today. Beside questions of the utmost importance for the whole community of immunologists, e.g, the intrinsic limits of immunological experiments performed at the bench on a limited number of selected models, the book covers several other facets of the eco-immunological approach, including host-parasite interactions, human aging and population immunology. Throughout the book the importance of population dynamics and evolutionary diversification of immune systems is frequently recalled, and makes the reader aware of the basic similarities and differences existing between humans and the models adopted for studying human immune system. The evidenced differences have been recently challenging the reliability of several established animal models and in the book it is discussed for the first time in analytical terms whether mice are reliable models of human inflammatory disorders.

Insect-pathogen interactions can be influenced by many factors including host life history, behavior and abiotic factors, such as chemical exposure. Additionally, exposure to pathogens can have transgenerational implications and influence the susceptibility of offspring. Understanding the outcomes of these interactions can also have implications for developing effective control strategies for insect pests. Asian longhorned beetles, Anoplophora glabripennis, are invasive wood borers which have been introduced into North America and Europe and the entomopathogenic fungus Metarhizium brunneum is being developed for their control. Studies were conducted to determine how sexual maturity, insect age, mating status (unmated vs mated), host thermoregulatory behavior, and prior maternal pathogen exposure influence A. glabripennis susceptibility to M. brunneum and ability to suppress a fungal infection, even across a generation. Additionally, potential mechanisms of synergy between M. brunneum and the neonicotinoid pesticide imidacloprid were investigated. Beetles did not exhibit thermoregulatory behavior although it would have been beneficial. Prior maternal pathogen exposure enhanced offspring survival but whether offspring survival was enhanced depended on the pathogen used to expose mothers and whether or not the pathogen was living or dead. Beetle susceptibility to A. glabripennis was iii also influenced by the age and mating status of beetles. We found that old beetles were not more susceptible than younger beetles and only found a cost of mating for mature but not old beetles. Finally we found that starvation may be a potential mechanism for the synergy between a pesticide (imidacloprid) and the fungal pathogen M. brunneum. These findings provide insight into insect-pathogen interactions and ecoimmunology in beetles. iv.

The second edition of Avian Immunology provides an up-to-date overview of the current knowledge of avian immunology. From the ontogeny of the avian immune system to practical application in vaccinology, the book encompasses all aspects of innate and adaptive immunity in chickens. In addition, chapters are devoted to the immunology of other commercially important species such as turkeys and ducks, and to ecoimmunology summarizing the knowledge of immune responses in free-living birds often in relation to reproductive success. The book contains a detailed description of the avian innate immune system, encompassing the mucosal, enteric, respiratory and reproductive systems. The diseases and disorders it covers include immunodepressive diseases and immune evasion, autoimmune diseases, and tumors of the immune system. Practical aspects of vaccination are examined as well. Extensive appendices summarize resources for scientists including cell lines, inbred chicken lines, cytokines, chemokines, and monoclonal antibodies. The world-wide importance of poultry protein for the human diet, as well as the threat of avian influenza pandemics like H5N1 and heavy reliance on vaccination to protect commercial flocks makes this book a vital resource. This book provides crucial information not only for poultry health professionals and avian biologists, but also for comparative and veterinary immunologists, graduate students and veterinary students with an interest in avian immunology. With contributions from 33 of the foremost international experts in the field, this book provides the most up-to-date review of avian immunology so far Contains a detailed description of the avian innate immune system reviewing constitutive barriers, chemical and cellular responses; it includes a comprehensive review of avian Toll-like receptors Contains a wide-ranging review of the "ecoimmunology" of free-living avian species, as applied to studies of population dynamics, and reviews methods and resources available for carrying out such research

This book discusses oxidative stress and hormesis from the perspective of an evolutionary ecologist or physiologist. In the first of ten chapters, general historical information, definitions, and background of research on oxidative stress physiology, hormesis, and life history are provided. Chapters 2-10 highlight the different solutions that organisms have evolved to cope with the oxidative threats posed by their environments and lifestyles. The author illustrates how oxidative stress and hormesis have shaped diversity in organism life-histories, behavioral profiles, morphological phenotypes, and aging mechanisms. The book offers fascinating insights into how organisms work and how they evolve to sustain their physiological functions under a vast array of environmental conditions.

Insects display a staggering diversity of mating and social behaviours. Studying these systems provides insights into a wide range of evolutionary and behavioural questions, such as the evolution of sex, sexual selection, sexual conflict, and parental care. This edited volume provides an authoritative update of the landmark book in the field, The Evolution of Insect Mating Systems (Thornhill and Alcock, 1983), which had such a huge impact in shaping adaptationist approaches to the study of animal behaviour and influencing the study of the evolution of reproductive behaviour far beyond the taxonomic remit of insects. This accessible new volume brings the empirical and conceptual scope of the original book fully up to date, incorporating the wealth of new knowledge and research of the last 30 years. It explores the evolution of complex forms of sex determination in insects, and the role of sexual selection in shaping the evolution of mating systems. Selection arising via male contest competition and female choice (both before and after copulation) are discussed, as are the roles of parasites and pathogens in mediating the strength of sexual selection, and the role that parental care plays in successful reproduction. The Evolution of Insect Mating Systems is suitable for both graduate students and researchers interested in insect mating systems or behaviour from an evolutionary, genetical, physiological, or ecological perspective. Due to its interdisciplinary and concept-driven approach, it will also be of relevance and use to a broad audience of evolutionary biologists.
