Book excerpt: Our aim in this volume, as in Volume I, HormonaI Correlates of Behavior: A Life Span View, has been to provide a critical assess ment of the state of behavioral endocrinology as weIl as the more usual summary of extant data. Each contributor was asked to probe the strengths and weaknesses of his area as candidly as possible. As aresult, we hope the reader will find this Volume useful as a reference source and as an honest evaluation of our present know ledge of the interaction between hormones and behavior. R. L.

Download or read book Avian Biology written by Donald S. Farner and published by Academic Press. This book was released on 2013-09-17 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avian Biology, Volume V is a collection of papers that deals with the biology of birds concerning their mechanics of flight and migration. The first paper describes the mechanics of bird flights such as gliding, soaring, and the energy requirements of this activity. Other papers investigate the control and metabolic physiology of migration, including flight restlessness and fat metabolism. Other topics cover migratory orientation research involving topographical, meteorological, inertial, magnetic, and celestial cues. Upon migration to different environments, birds have to adapt as their circadian and circannual rhythms are affected. One paper discusses the works of Wynne-Edwards, Aschoff and Wever, and Leopold and Eynon regarding their observations of bird migration cues. One author describes the vocal behavior in birds, including the dual sound theory where two sound sources can occur in each bronchus. Of interest to many in this paper is the description of the different stages in song development. Other papers discuss the incubation behavior of birds as well as the energetics involved. This book is suitable for zoologists, bird enthusiasts, and avian biologists.

Available in PDF, EPUB and Kindle. Book excerpt: The main objective of my work was to determine how the circadian system responds to aging in White-Throated Sparrows. The study used geriatric sparrows, aged at least 10 years in captivity, and monitored locomotor activity continuously. Birds were held under a 12/12 light dark cycle and then experienced a four hour phase shift forward, followed by a shift back to the original light cycle after entrainment for approximately one month in order to measure their ability to synchronize to new light schedules. The resulting data showed a variety of unique circadian manifestations including arrhythmic, nocturnal, with many birds maintaining their original phase of activity despite a shift in the light cycle. The second was to use MRI to compare the brain structure of three geriatric sparrows to three younger sparrows, aged around 2 years. A 7 Tesla machine was used to perform a series of MRI scans and Avizo 9.0 software was used to calculate volumes of the total brain, ventricles, hippocampus, hypothalamus, and the cerebellum. The older birds exhibited smaller hypothalamic volumes. From the actogram data we propose that the previously reported dawn and dusk oscillators are less coupled and their photic input has been differentially affected in the aged birds. The dawn oscillator correctly shifted and entrained to a new light schedule, while the dusk oscillator had reduced photic input and did not shift accordingly. These results are consistent with the hypothesis that the dusk oscillator relies on circadian time memory instead of reentraining to new light cycles.

Download or read book Animal Migration Orientation and Navigation written by Gauthreaux and published by Elsevier. This book was released on 2012-12-02 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal Migration, Orientation, and Navigation presents the various aspects of animal migration, including the evolution of migration, climatic and meteorological influences, and bioenergetics. This book discusses the physiological control, sensory systems, orientation and navigation, and biological clocks and phenology aspects of animal migration. Organized into five chapters, this book begins with an overview of the migration strategies of animals in the context of a space continuum. This text then explains the influence of short- and long-term climatic cycles on the spectrum of migratory patterns in nature. Other chapters consider the energetic requirements of different migration strategies and the energy stores of the migrants. This book discusses as well the physiological basis of animal migration, with emphasis on endocrinal findings on the timing and energetic aspects of different migration strategies. The final chapter deals with the mechanisms used in direction finding by migrating animals. This book is a valuable resource for biologists and ecologists.
