Although photo atlases in other fields of the life sciences have long been available to aid students in their studies, there has never been one for entomology. One reason for this is the great number of photos necessary for such a book to be of any value. Fortunately for students, Dr. Castner has spent the past 25 years photographing insects with his work appearing in everything from National Geographic to Ranger Rick. Dr. Castner's experience in teaching and working with students has allowed him to produce a work that exactly addresses their needs. His Photographic Atlas of Entomology is simple, thorough, user-friendly, and very reasonably priced. It should be a great help to any entomology student, as well as to the professors teaching entomology courses.
S2This guide has been prepared to help you estimate the extent and severity of discoloration and decay in northern hardwood trees. Though this certainly is not the last word on the subject, our research in this has progressed to the point where our findings, combined with the findings of others, can be put to practical use. By dissecting living trees and studying the organisms that infect them, we now know that discoloration and decay develop in certain definite patterns. And the patterns of discoloration and decay within the tree can be predicted from external signs. Discoloration and decay are the most serious defects of northern hardwood trees. In speaking of defect, we must distinguish between injury and damage. Injury harms the tree: damage lowers the quality of the wood. For example, a disease like vascular wilt may kill the tree but do no damage to the wood. But an insect like the cambium miner may do very little harm to the tree yet do great damage to the wood. The unseen damage done to a tree is important in the economics of forestry. Every operation in growing a tree, harvesting it, and converting it into products costs time and money. And after all the time and money have been spent on a tree, the product made from it may prove to be not worth the effort; and the tree might have been used more profitably for some other product that does not require high-quality wood. The increased use of veneer offers an illustration. A veneer log brings top prices. But its actual value may not become apparent till it is put on a lathe and peeled. A log that looks very good and sound to the core, may have minute streaks of discoloration scattered all through it, so that all the veneer it produces is badly streaked with defects. On the other hand, a log that has a rotten core surrounded by clear wood may produce the highest quality of veneer. So it is not so important how much discoloration and decay a tree has, but when these defects are in a tree. The pattern of the discoloration and decay- that's the important thing.S3.
