Ptilochronology
This is the first book to summarize the methods, conceptual issues and results of studies using the interpretation of feather growth rates as an index of nutritional condition in birds. The author has coined the term ptilochronology (literally, 'the study of feather time') to describe this technique, which relies on the fact that as a feather grows it produces visible growth bars. Both the technique and its conceptual foundations have been applied worldwide to numerous studies ofavian evolution, ecology, and conservation biology. The author reviews this work, chronicles the various criticisms that have been made, and describes how these have influenced the development of ptilochronology. He ...
The Mind of the Trout
How and why do trout think? How do they decide where to eat and which food to eat? Why do they refuse to behave as predicted, stumping anglers by rejecting a larger fly for a smaller one or not responding at all to anything in an angler’s box? How do trout know to bolt to one particular covered area after being hooked or flushed? Why can trout smell better than humans but not remember as well? Citing the most recent scientific findings in a readily understandable form, Thomas C. Grubb, Jr. addresses these questions and more in The Mind of the Trout. It is the first book to bring together many varied concepts of cognitive ecology as applied to trout and their salmonid relatives: char, salmon, grayling, and whitefish.
Current Ornithology
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. ...
Current Ornithology
Our purposes in this preface are, first, to reiterate our view of Current Ornithology's role; second, to describe briefly the contents of this vol ume; and third, to acknowledge the generous help of our Editorial Board and of the reviewers we have consulted about the contents of Volumes 13 and 14. As far as we know, Current Ornithology is the only English-lan guage publication currently devoted exclusively to extensive reviews and syntheses of topics pertaining to all aspects of the biology of birds. Its chapters deal with subjects falling under such diverse rubrics as ecology, evolution, behavior, phylogeny, behavioral ecology, anatomy and physiology, and conservation biology, but all focus primarily on birds. Its authors, whether members of the National Academy or young investigators just beginning their careers, are leading authorities on their subjects, and its referees are selected for their knowledge and expertise in the topics covered by the chapters they are asked to review.

Extraterrestrial Altruism
Extraterrestrial Altruism examines a basic assumption of the Search for Extraterrestrial Intelligence (SETI): that extraterrestrials will be transmitting messages to us for our benefit. This question of whether extraterrestrials will be altruistic has become increasingly important in recent years as SETI scientists have begun contemplating transmissions from Earth to make contact. Technological civilizations that transmit signals for the benefit of others, but with no immediate gain for themselves, certainly seem to be altruistic. But does this make biological sense? Should we expect altruism to evolve throughout the cosmos, or is this only wishful thinking? Is it dangerous to send messages ...
Snag Habitat Management
These proceedings include 41 papers focusing attention on the need to integrate management of snags - dead or deteriorating trees critical to needs of cavity-dependent wildlife - with other resource uses and demands. Sessions concentrated on management, habitat and species requirements, and monitoring and modeling.
