Excerpt from The Variability of Paper Birch Seed Production, Dispersal, and Germination
There appears to be no relationship between time of dispersal and size of seed crop; and in both the Maine and New Hampshire stands the bulk of the seed was dispersed every year before the ground was snow-covered. There is an advantage in this: seed dispersed on prepared seedbeds before snow falls will be held in place; seed falling on snow-covered seedbeds might be blown off.

Paperback. Zustand: New. Print on Demand. This book investigates the processes of decay and discoloration in three northern hardwood species: American beech, yellow birch, and sugar maple. The author positions his findings within a broader understanding of wood decay and discoloration as they occur in living trees. The author challenges the existing body of knowledge on wood decay, which historically has focused on decay in sterilized wood blocks and the later stages of decay and discoloration in living trees. In doing so, he draws attention to the importance of the earlier stages of these processes and the critical role of bacteria and non-hymenomycetous fungi in their development. The author's work expands our understanding of the initial stages of wood decay and discoloration, which has implications for forest management and the study of tree health.
