Book Description
The purpose of this document is to provide an information base on the effects of aircraft noise and sonic booms on various animal species. Such information is necessary to assess potential impacts to wildlife populations from proposed military and other flight operations. To develop this document the National Ecology Center conducted a literature search of information pertaining to animals and wildlife. Information concerning other types of noise was also gathered to supplement the lack of knowledge on the effects of aircraft noise. The bibliographic abstracts in this report provide a compilation of current knowledge. No attempt was made to evaluate the appropriateness or adequacy of the scientific approach of each study. (sdw).

Book Description
This book examines the current literature and knowledge on the evolution and ecology of all the birds named as eagles, with particular emphasis on the larger species. It also examines the past and current relations between eagles and people, including habitat change and conservation issues. Eagle ecologies and conservation are currently seriously impacted by human activities such as industrialization, urbanization, pollution, deforestation and hunting. Some eagle species have consequently experienced extreme population changes. There are, however, some positive developments. Eagles have a strong, historic bond with human civilization, due to their status as the world’s most charismatic birds. Conservation policies have also been successful in repopulating some ecosystems with breeding eagles. Therefore, despite the complexity of this relationship, there may yet be hope for this unique species group, frequently rated as the kings of birds, and symbolic of human power, ambition, royalty, nationality, and even concepts of God. It is hoped that this book will contribute to the further understanding of these unique and fantastic birds.

Book Description
This multi-disciplinary approach to conservation of endangered species in captivity is organized taxonomically and by scientific discipline. The seven taxonomic groups included are invertebrates; fish, reptiles and amphibians, birds, marine mammals, primates, and other mammals. Within each taxonomic group, four scientific disciplines are explored: conservation, reproductive physiology, behavior, and captive design. Conservation chapters summarize the status of the taxonomic group both in the wild and in captivity. Reviewed in the reproductive physiology chapters are anatomy, endocrinology and physiology for females and males of the taxonomic group. In the section on behavior the functions of captive animal research, the methods used, and the problems encountered are discussed. And, in examining captive design the authors provide a general historical outline of the philosophies, trends, and scientific issues for the targeted taxonomic group.
