Book Description
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

Book Description
Birds have and continue to fascinate scientists and the general public. While the avian respiratory system has unremittingly been investigated for nearly five centuries, important aspects on its biology remain cryptic and controversial. In this book, resolving some of the contentious issues, developmental-, structural- and functional aspects of the avian lung-air sac system are particularized: it endeavors to answer following fundamental questions on the biology of birds: how, when and why did birds become what they are? Flight is a unique form of locomotion. It considerably shaped the form and the essence of birds as animals. An exceptionally efficient respiratory system capacitated birds to procure the exceptionally large quantities of oxygen needed for powered (active) flight. Among the extant air-breathing vertebrates, comprising ~11,000 species, birds are the most species-rich-, numerically abundant- and extensively distributed animal taxon. After realizing volancy, they easily overcame geographical obstacles and extensively dispersed into various ecological niches where they underwent remarkable adaptive radiation. While the external morphology of birds is inconceivably uniform for such a considerably speciose taxon, contingent on among other attributes, lifestyle, habitat and phylogenetic level of development have foremost determined the novelties that are displayed by diverse species of birds. Here, critical synthesizes of the most recent findings with the historical ones, evolution and behavior and development, structure and function of the exceptionally elaborate respiratory system of birds are detailed. The prominence of modern birds as a taxon in the Animal Kingdom is underscored. The book should appeal to researchers who are interested in evolutionary processes and how adaptive specializations correlate with biological physiognomies and exigencies, comparative biologists who focus on how various animals have solved respiratory pressures, people who study respiration in birds and other animals and ornithologists who love and enjoy birds for what they are – profoundly interesting animals.

Book Description
Brood parasitism has become one of the most flourishing areas of research in evolutionary ecology and one of the best model systems for investigating coevolution. This subject has undergone remarkable advances during the last two decades, but has not been covered by any book in the 21st century. This book offers a comprehensive and up-to-date overview of the fascinating field of avian brood parasitism. The topics covered include conspecific brood parasitism; evolution and phylogenetic history of avian brood parasites; parasitic behaviour used by brood parasites; adaptations and counter-adaptations of brood parasites and their hosts at every stage of the breeding cycle (before laying, egg, chick and fledgling stages); factors affecting the evolution of host defences and parasitic attacks; the role of phenotypic plasticity in host defences; mechanisms driving egg recognition and rejection; evolution of nest sharing or nest killing by brood parasite chicks; begging behaviour in parasitized nests and food delivery by host adults; and recognition of conspecifics by juvenile brood parasites. This volume provides a comprehensive reference resource for readers and researchers with an interest in birds, behaviour and evolution, as well as a source of hypotheses and predictions for future investigations into this dynamic subject.

Book Description
The United Nations has recently released population projections suggesting that the global population will reach 9.7 billion by 2050 and exceed 11 billion by 2100. The increase in the world population may lead to food shortages, especially that of food protein. A variety of food protein alternatives have been developed and launched to the market to solve the problem of diminishing resources, particularly of land and water. In fact, animal protein has become a target in recent times for its greenhouse gas emissions. However, the UN has projected a steady increase in demand for poultry meat over the upcoming decades. The main demand will be from middle class and low-income families in particular and is due mainly to its high production efficiency for inexpensive, good-quality proteins. Nonetheless, due to limited resources, the poultry meat produced must be of high quality to ensure food security and minimize food waste.

Book Description
At present, less than 30% of researchers worldwide are women. Long-standing biases and gender stereotypes discourage girls and women from pursuing a career in science, technology, engineering and mathematics (STEM) research. Science and gender equality are, however, essential to ensure sustainable development. Although underrepresented, and often unacknowledged, female researchers have been crucial to scientific advances. In order to change traditional mindsets, gender equality must be promoted, stereotypes defeated, and girls and women should be encouraged to pursue STEM careers.

Book Description
Sturkie's Avian Physiology, Seventh Edition is the classic comprehensive single volume on the physiology of domestic as well as wild birds. This latest edition is thoroughly revised and updated and features several new chapters with entirely new content on such topics as vision, sensory taste, pain reception, evolution, and domestication. Chapters throughout have been greatly expanded due to the many recent advances in the field. This book is written by international experts in different aspects of avian physiology. For easy reading and searches, this book is structured under a series of themes, beginning with genomic studies, sensory biology and nervous systems, and major organs. The chapters then move on to investigate metabolism, endocrine physiology, reproduction, and finally cross-cutting themes such as stress and rhythms. New chapters on feathers and skin are featured as well. Sturkie's Avian Physiology, Seventh Edition is an important resource for ornithologists, poultry scientists, and other researchers in avian studies. It is also useful for students in avian or poultry physiology, as well as avian veterinarians. - Stands out as the only single volume devoted to bird physiology - Features updates, revisions, or additions to each chapter - Written and edited by international leaders in avian studies
