This book is concerned with the management of natural resources, in particular with the management of the resource called fish and wild life. It recognizes that successful management of a natural resource requires the design of research and development programs.

Successful natural resource administration demands the well-exercised ability to deal with the interests of many actors--including the public and wildlife--in a balanced, constructive way. The authors of this book, recognized as experts in the management of natural resources, discuss management with special emphasis on fish and other wildlife. Their approach to management development constantly searches for creative compromises that protect today's wildlife for future generations while maximizing present social and economic benefits. Their comprehensive treatment also includes a discussion of such topics as the interaction of human management of wildlife with natural regulation of wildlife; the need for sound research and development programs; the importance of public participation in the management of natural resources; and the political and administrative context in which resource management must take place.

This book is a volume in the Penn Press Anniversary Collection. To mark its 125th anniversary in 2015, the University of Pennsylvania Press rereleased more than 1,100 titles from Penn Press's distinguished backlist from 1899-1999 that had fallen out of print. Spanning an entire century, the Anniversary Collection offers peer-reviewed scholarship in a wide range of subject areas.

How does one analyze a set of real events in order to isolate and define the important variables that appear to be operating? Determine the structure of relationships between the variables? Represent the content and structure of a system of events in the form of a mathematical equation? The student of model-building seeks answers to many such questions that are not adequately dealt with in the existing literature. In this book, eight experts fill an important need by offering a range of approaches to model-building in the behavioral sciences. The papers in this collection reflect the contributors common concern to improve the teaching methodology in those fields in which model-building is increasingly the primary focus of research. The insights they provide will be of crucial interest to students of model-building is increasingly the primary focus of research. The insights they provide will be of crucial interest to students of model-building and those who instruct them in the preconditions for constructing workable models of behavior."
