Download or read book Physiological Adaptations for Breeding in Birds written by Tony D. Williams and published by Princeton University Press. This book was released on 2012-08-05 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiological Adaptations for Breeding in Birds is the most current and comprehensive account of research on avian reproduction. It develops two unique themes: the consideration of female avian reproductive physiology and ecology, and an emphasis on individual variation in life-history traits. Tony Williams investigates the physiological, metabolic, energetic, and hormonal mechanisms that underpin individual variation in the key female-specific reproductive traits and the trade-offs between these traits that determine variation in fitness. The core of the book deals with the avian reproductive cycle, from seasonal gonadal development, through egg laying and incubation, to chick rearing. Reproduction is considered in the context of the annual cycle and through an individual's entire life history. The book focuses on timing of breeding, clutch size, egg size and egg quality, and parental care. It also provides a primer on female reproductive physiology and considers trade-offs and carryover effects between reproduction and other life-history stages. In each chapter, Williams describes individual variation in the trait of interest and the evolutionary context for trait variation. He argues that there is only a rudimentary, and in some cases nonexistent, understanding of the physiological mechanisms that underpin individual variation in the major reproductive life-history traits, and that research efforts should refocus on these key unresolved problems by incorporating detailed physiological studies into existing long-term population studies, generating a new synthesis of physiology, ecology, and evolutionary biology.

Download or read book Behavioral Ecology of Neotropical Birds written by Juan Carlos Reboreda and published by Springer. This book was released on 2019-04-24 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers central aspects of behavioral ecology, including sexual selection, social and genetic mating systems, cooperative breeding, brood parasitism, brood reduction, migration, personalities and communication. Over the past several years, Neotropical bird species from temperate to tropical latitudes of South America have been extensively studied, yielding valuable insights into the evolutionary mechanisms that drive their behavioral traits. In this book, international experts provide a general overview of main behavioral aspects. They also present the main findings of their work, including experimental approaches to testing the most accepted behavioral theory in their model systems. In closing, they propose new theoretical frameworks and future research directions. As such, the book provides a comprehensive and updated guide for all researchers, students and professionals whose work involves the study and management of birds across the Neotropical region.

Download or read book Nests, Eggs, and Incubation written by D. Charles Deeming and published by OUP Oxford. This book was released on 2015-08-13 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nests, Eggs, and Incubation brings together a global team of leading authorities to provide a comprehensive overview of the fascinating and diverse field of avian reproduction. Starting with a new assessment of the evolution of avian reproductive biology in light of recent research, the book goes on to cover four broad areas: the nest, the egg, incubation, and the study of avian reproduction. New research on nest structures, egg traits, and life history is incorporated, whilst contemporary methodologies such as self-contained temperature probes and citizen science are also discussed. Applied chapters describe how biological knowledge can be applied to challenges such as urbanisation and climate change. The book concludes by suggesting priorities for future research. This book builds upon the foundations laid down by Charles Deeming's 2002 work Avian Incubation (available for readers of this book to access online for free), much of which remains relevant today. Read in conjunction with this previous volume, it provides an up-to-date and thorough review of egg biology, nest function, and incubation behaviour, which will be an essential resource for students of avian biology, as well as both professional and amateur ornithologists working in the field of avian reproduction.

Available in PDF, EPUB and Kindle. Book excerpt: The Conference Theme was: "Moving Africa forward through Engineering, Technology and Innovation". The conference brought together academics, researchers and industrialists from many disciplines, in particular those that have the most impact on Africa's Development. Most conferences on the continent have covered limited disciplines and therefore the opportunity has been lost sharing information, results and knowledge in a way which can solve the many contentious issues, most of which can be solved through a multidisciplinary approach.

Available in PDF, EPUB and Kindle. Book excerpt: Widespread across open lands and cities of Europe, Africa, and Asia, the common kestrel (Falco tinnunculus) is one of the most abundant and studied birds of prey. This book brings together and synthesises the results of research on kestrels for professional ornithologists and scientists that seek to consolidate a vast body of literature. It is also a reference for those readers who may not have the depth of scientific knowledge to navigate new fields of scientific enquiry. It examines many aspects of the species' biology, from the reproductive strategies to the behavioural and demographic adaptations to changes of environmental conditions. It also discusses the roles of physiology and immunology in mediating the adaptability of kestrels to the ongoing environmental changes with a particular focus on contaminants. This volume presents new and exciting avenues of research on the ecology and behaviour of the common kestrel.

Download or read book Maternal Effects As Adaptations written by Timothy A. Mousseau and published by Oxford University Press. This book was released on 1998-06-18 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mothers have the ability to profoundly affect the quality of their offspring--from the size and quality of their eggs to where, when, and how eggs and young are placed, and from providing for and protecting developing young to choosing a mate. In many instances, these maternal effects may be the single most important contributor to variation in offspring fitness. This book explores the wide variety of maternal effects that have evolved in plants and animals as mechanisms of adaptation to temporally and spatially heterogeneous environments. Topics range from the evolutionary implications of maternal effects to the assessment and measurement of maternal effects. Four detailed case studies are also included. This book represents the first synthesis of the current state of knowledge concerning the evolution of maternal effects and their adaptive significance.

Download or read book Harriers of the World written by Robert E. Simmons and published by Oxford University Press, USA. This book was released on 2000 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harriers are a charismatic group of birds of prey with a worldwide distribution that have long fascinated bird watchers and scientists. Here for the first time the biology of the world's harriers is treated within one over, in readily accessible language. There are detailed comparisons of northern and southern species, descriptions of mating systems and population dynamics life histories, and insights into the selection pressures shaping the birds' life histories. The author addresses such questions as how females choose partners against their apparent self- interest, how they adjust to prevailing circumstances to produce the perfect clutch size, and what underlies variations in size dimorphism and copulation patterns. New information resulting from a DNA examination of the group reveals three new harrier species and allows construction of a new phylogeny of the harriers. The author's twin brother brings the book to life by fine original line drawings of these impressive birds. It will be a treat for all raptor biologists, amateur raptophiles, and behavioral ecologists interested in birds of prey.

Download or read book Cooperative Breeding in Vertebrates written by Walter D. Koenig and published by Cambridge University Press. This book was released on 2016-01-07 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cooperative breeders are species in which individuals beyond a pair assist in the production of young in a single brood or litter. Although relatively rare, cooperative breeding is widespread taxonomically and continues to pose challenges to our understanding of the evolution of cooperation and altruistic behavior. Bringing together long-term studies of cooperatively breeding birds, mammals, and fish, this volume provides a synthesis of current studies in the field. The chapters are organised by individual studies of particular species or (in the case of mole-rats) two closely related cooperatively breeding species. Each focuses not only on describing behavior and ecology but also on testing evolutionary hypotheses for the form and function of the diverse and extraordinary cooperative breeding lifestyles that have been discovered. This unique and comprehensive text will be of interest to graduate students and researchers of behavioral ecology and the evolution of cooperation.

Download or read book Avian Energetics and Nutritional Ecology written by C. Carey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: A symposium held in 1973 chaired and organized by William R. Dawson was the first major attempt to summarize and synthesize the existing information in the then emerging field of avian energetics. The symposium featured papers by James R. King, William A. Calder III, Vance A. Tucker, and Robert E. Ricklefs and com mentaries by George A. Bartholomew, S. Charles Kendeigh, and Eugene P. Odum. The proceedings of the symposium, Avian Energetics (Paynter 1974), played a critical role in stimulating interest and research in the field of avian energetics. Some twenty-odd years later, we are making another attempt to summarize the information in the field of avian energetics. Some obvious differences exist be tween its predecessor and this volume. Numerous improvements in methodology, such as the use of doubly labeled water to estimate metabolism in free-living birds, now allow researchers to ask questions that could not be addressed previ ously. Second, consideration of nutrition is now inseparable from that of energet ics. This merger is necessary not only because food intake is the source of both en ergy and nutrients but also because one or more nutrients, rather than energy, can be limiting for a given species in a particular instance. Finally, the study of ener getics and nutritional ecology, particularly in birds and mammals, has grown so dramatically that a single volume can now only partially cover the range of possi ble topics and can catalogue only a sampling of all the studies on the subject.
