Trees
The purpose of this publication is to clarify further the tree decay concept that expands the classical concept to include the orderly response of the tree to wounding and infection-compartmentalization-and the orderly infection of wounds by many microorganisms-successions. The heartrot concept must be abandoned because it deals only with decay-causing fungi and it states that these fungi grow unrestricted through heartwood after infection of fresh wounds. The heartrot concept emphasizes descriptions ... [Information of the supplier]

Plot studies often face problems with the identification of both fertile and sterile material. Numerous books need to be taken into the field to aid in identification of specimens. The Virtual Tree Guide of the Guianas which will available on CD and accessible through the WWW may assist researchers in finding a quick match of those species that are considered to be able to reach sizes over 10 cm DBH.
Over 4000 specimens have been digitized in the Utrecht Herbarium. They are organized by genus and ... [Information of the supplier]

Forest geneticists are frequently confronted with practical questions concerning the origin, the genetic variability, or the adaptability of trees, stands, or forest reproductive material. The posers of these questions can be biologists, ecologists, foresters, private forest owners, firms dealing with forest reproductive material, nature conservation organizations, and, of course, the forest geneticists themselves for their basic research. Awareness is growing within these groups that many of these ... [Information of the supplier]
