Take some of the mystery out of a walk in the woods with this new field guide from the author of Reading the Forested Landscape. Thousands of readers have had their experience of being in a forest changed forever by reading Tom Wessels's Reading the Forested Landscape. Was this forest once farmland? Was it logged in the past? Was there ever a major catastrophe like a fire or a wind storm that brought trees down? Now Wessels takes that wonderful ability to discern much of the history of the forest from visual clues and boils it all down to a manageable field guide that you can take out to the woods and use to start playing forest detective yourself. Wessels has created a key—a fascinating series of either/or questions—to guide you through the process of analyzing what you see. You’ll feel like a woodland Sherlock Holmes. No walk in the woods will ever be the same.

The first volume in this series appeared in 1977, the second in 1980. From these volumes and the present one, some research trends in chemical communication can be perceived. In the 1977 volume, studies on 13 animal taxa were reported. In the present volume, the number is 25. This taxonomie diversi fication of research since the first volume of this series demon strates the wide variety of ecological adaptions, although no new general principles of chemical communication have ernerged. Further more, divergences in chemical comrnunication below the species level have become more apparent. In general, more sophisticated observa tions and techniques have led to greater awareness of the com plexities in chemical communication. As such awareness has also developed in the field of insect chemical communication, there has been a corresponding increase in the identification of the chemical compounds involved. However, in the vertebrates, no such correlation exists; in the present volume, conclusive chemical identifications of semiochemicals are remarkable by their paucity.
