This beautifully illustrated book (sketches by Ned Smith) ties together ecology and evolution, natural selection and animal behavior. It is a general ecology textbook, but it is more than that. It could serve as a reference book in bio-geography and constitutes an excellent beginning for students of wildlife management. There are excellent accounts of the major habitats, lakes, ponds, bogs, swamps, marshes, streams, estuaries, the seashore, the forest, the grasslands, the desert, the tundra. Excellent bibliographies are provided for further study.
