I went over to Borders immediately and bought 2 books: "Insects of the Great Lakes Region" by Gary Dunn, and "Fresh Water" by E. C. Pielou. I had finished 2 books by Pielou this year, "After the Ice Age" and "The World of Northern Evergreens". I had been meaning to summarize some interesting factoids from the latter book and from another book that have some relevance to Forest Ecology, so here gooes without further procrastination, first from the Evergreens book: Chapter 5, "The Life and Growth of a Conifer" * Angiosperms (angeion = vessel) contain vessels in the wood, that can be seen in the stumps. Vessels are all about the same size, so annual rings are harder to see than in gymnosperms. But rays are easier to see in angiosperms. * Gymnosperms contain tracheids instead of vessels. They are less efficient at transporting water than vessels, so should transpire much less water than angiosperms. Tracheid cells are dead; in the heartwood they are clogged with resins, gums, and tannins, and cannot conduct sap. Color contrast between heartwood and sapwood is low in spruce and fir. * In a leaning trunk or branch, gymnosperms develop compression wood: wider rings on the underside. Angiosperms develop tension wood: wider rings on the upperside. But most of the angiosperm trees I've checked do not show the latter pattern? * Conifers develop spiral grain (the chains of tracheids) in the wood: left spiral when young, turning to right spiral when mature. Usually can only be seen when the bark has fallen off, except Arbor Vitae, where the bark often show the spiral grain. * On some conifers, the white bands along the leaves are stomata; under a hand lens they show up as tiny dots, which are wax covering the cuticle. She says you can see this on hemlock, fir, Douglas-fir, and Common Juniper. Unless I'm mistaken, I also saw them on a spruce (probably Picea abies) today. Chapter 8, "The Elements": * Conifers do not resprout from stump. From "Reading the Forested Landscape," by Tom Wessels: Chapter 1, "The Age Discontinuity" * Pines, spruce, and oaks that are heat-killed are very rot resistant and can remain snags for over 50 years. Chapter 3, "A Study in Stumps" * Conifer logs decay from outside in. Their heartwood stores toxic substances that are resistent to insects and fungi. Hardwood trees decay from inside out, or uniformly. Beech and maple logs can develop black fungus on bark that look like charcoal. * Root grafting can allow stumps to continue low-level growth. Sometimes can see growth rings inside the bark above the cut. * Hemlock bark is very rot resistant and supports little growth of moss or lichen, due to high tannin content. Chapter 6, "Pillows and Cradles" * Beech, maple, and birch logs decay too quickly to develop moss. Little moss on oak logs due to rot-resistant sapwood. Conifer logs most often moss covered: rot slowly from outside in. A moss-covered log can serve as a "nurse log" for the germination of other trees.
