Current Ornithology (Current Ornithology #16)

by Val Nolan Jr. Charles F. Thompson

Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review 1) fields in which abundant recent literature will benefit from synthesis and organization, 2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, and 3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.

Current Ornithology (Current Ornithology #12)

by D. M. Power

In Volume 12, eminent international ornithologists further elucidate endocrinological correlates of mating strategies and hormones and reproductive behavior; assess the value of the ''brood reduction hypothesis'' in explaining ''the paradox of hatching asynchrony''; and explore the validity and sensitivity of growth bands in feathers as an indication of nutritional condition and the use of feather banding in studying growth. Chapters are well supported with charts, maps, schematic diagrams, and photographs. Current Ornithology is the only English-language publication currently devoted exclusively to extensive reviews and synthesis of topics pertaining to all aspects of the biology of birds. Chapters fall under such diverse rubrics as ecology, evolution, behavior, phylogeny, behavioral ecology, anatomy and physiology, and conservation biology. All authors are leading authorities on their subjects, and each chapter is refereed by experts in the topics covered. Although all chapters focus primarily on birds, some topics, such as the social cognition of birds as compared to primates (Volume 13), have significant application to disciplines outside of ornithology. Current Ornithology aims to provide an accessible, up-to-date, accurate source of data and to contribute to conceptual generalization and unification across the biological sciences.

Current Ornithology (Current Ornithology #6)

by D. M. Power

This edited series has three principal goals. The first is to provide information in a relatively concise way for researchers needing an over­ view of specific disciplines. The second is to provide an update on specific schools of thought, bringing together ideas from colleagues whose works often appear in a variety of journals. And the third is to stimulate and suggest directions for new research. Volume 6 continues the tradition established by the previous editor and editorial board in providing new information, updating our understanding of specific dis­ ciplines, and stimulating new research. In the first chapter, Randall Breitwisch examines mortality patterns and sex ratios in monogamous birds. He argues that there are many more components to measuring parental investment than are often re­ alized; our knowledge is weak in several areas. Understanding the evo­ lution of mating systems depends on better distinguishing the different intensities of natural selection that operate on males and females. Greg­ ory Butcher and Sievert Rohwer develop a framework for assessing the role of colorfulness in birds. They propose several hypotheses to test and advocate evaluating more than one hypothesis at a time. Future work on the evolution of distinctive coloration and of sexual and age dimorphism must take these ideas into account.

Current Perspectives on the Functional Design of the Avian Respiratory System (Zoological Monographs #8)

by John N. Maina

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.

Current Research in Sports Sciences

by R. Maughan V. A. Rogozkin

There are two main reasons for pursuing research in the Sports Sciences. Firstly, by studying responses to exercise, we learn about the normal function of the tissues and or­ gans whose function allows exercise to be performed. The genetic endowment of elite ath­ letes is a major factor in their success, and they represent one end of the continuum of human performance capability: the study of elite athletes also demonstrates the limits of human adaptation because nowhere else is the body subjected to such levels of intensive exercise on a regular basis. The second reason for studying Sports Science is the intrinsic interest and value of the subject itself. Elite performers set levels to which others can as­ pire, but even among spectators, sport is an important part oflife and society. of top sport and elite performers, there is also another reason Apart from the study for medical and scientific interest in sport. There is no longer any doubt that lack ofphysi­ cal activity is a major risk factor for many of the diseases that affect people in all coun­ tries: such diseases include coronary heart disease, obesity, hypertension, and diabetes. An increased level of recreational physical activity is now an accepted part of the prescription for treatment and prevention of many illnesses, including those with psychological as well as physical causes. An understanding of the normal response to exercise, as well as of the role of exercise in disease prevention, is therefore vital.

Current Thoughts on Dementia: From Risk Factors to Therapeutic Interventions

by Ghulam Md Ashraf Md. Sahab Uddin

This informative book discusses the latest research on the risk factors and therapeutics in dementia. WHO calls dementia a public health priority. Dementia manifests as a group of symptoms associated with decline in memory or other thinking skills and is severe enough to reduce a person's ability to perform everyday activities. It occurs frequently among elderly people, but it is not necessarily part of the normal aging process. The book has been divided into two broad sections. The first section reviews the risk factors involved in developing dementia, including various medical conditions, lifestyle choices, as well as genetics. The latter section describes various therapeutic interventions in dementia. Although there is no known cure for dementia, this book underlines the current treatment strategies that could momentarily reduce the symptoms and improve the quality of life of the patients. This book highlights the global effort to find better ways to halt the progression of dementia and develop novel therapeutic strategies. The book would be an interesting read for advanced graduate students and researchers working in the field of neuroscience, genetics, and medicine. It will generate good interest to neurologists, psychiatrists, geriatricians, cardiologists, internal medicine practitioners, epidemiologist, and public health workers.

Current Topics in Primate Vocal Communication

by Elke Zimmermann, John D. Newman and Uwe Jürgens

More than 25 years ago, the first major review of primate communication appeared (Altmann, 1967). Since then, information on the communicative abilities of primates increased rapidly, resulting, 15 years later, in the appearance of the first volume in which signaling systems were analyzed in a broader variety of primate groups within an evolutionary perspective (Snowdon, Brown and Petersen, 1982). Seven years later, the first volume dedicated solely to primate vocal communication appeared (Todt, Goedeking and Symmes, 1988) and another four years later a volume followed in which nonverbal vocal communication in non-human primates and human infants was compared (Papousek, Jurgens and Papousek, 1992). None of these volumes, however, provided information about current technical advances in the field of bioacoustics, especially in digital sound analyzing systems, which offer primatologists, anthropologists and linguists nowadays a variety of rapid methods for analyzing human speech and non-human primate vocalizations in a quantitative and comparative way. Choosing the right method is difficult if a synopsis of these tools is lacking. Furthermore, information was particularly lacking on the natural signaling systems of two important primate groups, the prosimians and the apes. Likewise, new and unexpected insights into the ontogeny and evolution of vocal communication were gained during the past few years by the use of highly sophisticated sound analysis and statistical techniques.

Current Topics in Vector Research: Volume 4 (Advances in Disease Vector Research #4)

by M. E. Coan J. E. Duffus B. F. Eldridge F. E. Gildow A. L. Hicks J. Kramer P. G. Lawyer D. Tonkyn R. F. Whitcomb D. G. Young

Current Topics in Vector Research is based on the premise that to un­ derstand the whole, one must first understand the component parts and how they interact. Here in Volume 4, as well as in future volumes, vector, pathogen, and host will be treated both individually and as integral parts of multifaceted transmission systems. It is our intention to present up-to­ date, coherent syntheses of the latest findings in vector research, suggest promising frontiers for future research, and call attention to possible prac­ tical applications of our present understandings of pathogen-vector-host interactions. To realize our goals, we invite world-renowned, veteran sci­ entists as well as neophytes to report on their individual areas of expertise. Where appropriate, authors are encouraged to draw conclusions and pro­ pose hypotheses that stimulate additional thinking and research or oth­ erwise further our understanding of vector transmission cycles and how such cycles might be interrupted. It is our hope that readers will agree that we are serving these objectives and creating a milieu for specialists and generalists in vector research to maintain rapport and understanding.

Current Trends in Immunity and Respiratory Infections (Advances in Experimental Medicine and Biology #1108)

by Mieczyslaw Pokorski

The purpose of this book is to disseminate and deliberate on the latest knowledge concerning immunity and its role in protection and fight against microorganism invasion. The articles tackle both humoral and cellular immunity, and their interconnectivity. The former involves B cells that recognize invading pathogens and create the antibody-mediated response, which when memorized provides future immunity. The latter involves mostly T cells, exemplified by cytotoxic or killer cell destroying the pathogens, or helper cells stimulating B cells to produce antibodies to bind and neutralize the pathogens. T cells act through release of cytokines, interleukins, and other bioactive mediators. Neutrophils play a key role in innate immunity against bacterial infections. The process of NETosis is a recently unraveled sophisticated defense mechanism, consisting of the formation of neutrophil extracellular traps that catch, immobilize, and remove pathogens from the body. Dysfunction of immunity is indisputably conducive to the propensity for infections, particularly respiratory tract infections, as the airways are the first line of defense against invading pathogens. Pathogens can rapidly evolve and adapt to avoid detection by the immune system. The case in point is the influenza virus. The articles report on the epidemiology, diagnostics, serology, complications, and the process of acquired immunity due to vaccination against influenza and influenza-like infections in recent epidemic seasons. The book is a blend of medical research and practice. It is intended for academic scientists, research scholars, clinicians, family doctors, and healthcare professionals.
