Book Description
This book reexamines current knowledge on the evolution, ecology, and conservation biology of both New World vultures (Cathartidae) and Old World vultures (Accipitridae) and seeks answers to past and present regional extinctions, colorizations, and conservation questions. Extinct species of both families are examined, as is the disputed evidence fo

Book Description
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.

Book Description
"This is an amazingly compact, up-to-date history of the politics and biological research of the California Condor. It will be invaluable for biology students who want to review a case study of an endangered species and for environmental planners considering the highly political nature of rare-species conservation."—Allen Fish, Director, Golden Gate Raptor Observatory "As one of the most visible, dramatic, and controversial examples of intensive conservation management in modern times, the California Condor makes a good story. The Snyders' work is exemplary. This is a solid introduction to the subject and an excellent contribution to the press's natural history series."—Walter Koenig, Hastings Natural History Reservation, University of California
