This new edition is the most readable invertebrate biology text you'll find. Respected author Jan Pechenik has designed Biology of the Invertebrates for one-quarter and one- semester courses. The text covers all phyla of invertebrates; emphasizes the unifying characteristics within each group; and prepares students to read and understand the primary research literature. All chapters in the third edition contain excellent reference sections that have been updated to reflect the latest information about physiology, systematics, and phylogenetic relationships. You'll also find material covering recent findings using molecular techniques.
A readable introduction to the biology of each group of invertebrates, emphasizing those characteristics that set each group apart from the others, as well as the basic vocabulary and grammar of invertebrate zoology. Includes end-of-chapter suggestions for further research with references from the primary literature. This third edition contains expanded material in areas including classification schemes, protozoans, molluscs, evolutionary relationships, and social insects. Contains a glossary and b&w photos and illustrations. Annotation c. Book News, Inc., Portland, OR (booknews.com)
