I was asked to introduce this volume by examining "why a knowledge of ecosys tem functioning can contribute to understanding species activities, dynamics, and assemblages." I have found it surprisingly difficult to address this topic. On the one hand, the answer is very simple and general: because all species live in ecosystems, they are part of and dependent on ecosystem processes. It is impossible to understand the abundance and distribution of populations and the species diversity and composition of communities without a knowledge of their abiotic and biotic environments and of the fluxes of energy and mat ter through the ecosystems of which they are a part. But everyone knows this. It is what ecology is all about (e.g., Likens, 1992). It is why the discipline has retained its integrity and thrived, despite a sometimes distressing degree of bickering and chauvinism among its various subdisciplines: physiological, be havioral, population, community, and ecosystem ecology.

A straightforward, easy-to-understand book that teaches you how to directly communicate with animals. Animal Talk teaches you how to open the door to your animal friends’ hearts and minds without resorting to magic tricks or wishful thinking. Every creature can be reached through telepathic communication—from your tabby cat or cockatiel to the wasps that build nests in the eaves of your home or even the common flea—you just have to be open to the idea, and mind-to-mind communication will be in your grasp. In addition to an entire chapter devoted to teaching people how to develop mind-to-mind communication with animals, Animal Talk includes a discussion of freedom, control, and obedience, understanding behaviors from the animal’s point of view, how to handle upsets between animals, tips on nutrition for healthier pets, and the special relationship between animals and children.

An invaluable student-tested study aid, this primer, first published in 2007, provides guided instruction for the analysis and interpretation of genetic principles and practice in problem solving. Each section is introduced with a summary of useful hints for problem solving and an overview of the topic with key terms. A series of problems, generally progressing from simple to more complex, then allows students to test their understanding of the material. Each question and answer is accompanied by detailed explanation. This third edition includes additional problems in basic areas that often challenge students, extended coverage in molecular biology and development, an expanded glossary of terms, and updated historical landmarks. Students at all levels, from beginning biologists and premedical students to graduates seeking a review of basic genetics, will find this book a valuable aid. It will complement the formal presentation in any genetics textbook or stand alone as a self-paced review manual.
