All species play a vital role in their biological communities, and the removal of just one can have a noticeable and catastrophic ripple effect. This book brings together experts on 88 endangered animal species of Texas and includes brief descriptions of the processes that state and federal agencies employ to list and protect designated species.

Vividly illustrated with many color pictures, this introduction to the basic concepts of ecology interprets the relationship between plants and animals in terms of their roles as producers or consumers of energy. Throughout the book, examples are taken from two familiar ecosystems--a woodland and an intertidal rocky shore. How such complex systems work is explained by following the flow of energy as it is captured by plants and transferred to other living things as they feed. Intended for older children and young adults interested in ecology, this book is distinguished by its readable and engaging style and by its supurb color illustrations.
