Deforestation In Nineteenth-Century Maine: The Record Of Henry David Thoreau, Geoffrey Paul Carpenter
Deforestation In Nineteenth-Century Maine: The Record Of Henry David Thoreau, Geoffrey Paul Carpenter
Maine History
Thoreau’s Maine Woods, a record of three trips made between 1846 and 1857, offers a combination of literary metaphor and precise botanical and topographical observation. Comparing Thoreau’s journals with recent advances in forest ecology, author Geoffrey Paul Carpenter reveals a detailed picture of the various ways in which logging activity changed the forests, lakes, and rivers of Maine. Carpenter demonstrates that a precise understanding of forest history depends not only on traditional statistical sources, but also on the subjective personal testimony found in the literary record.

Seedling development is described for Chamaesyce hirta, C. hypericifolia, and C. mesembrianthemifolia as discerned by light microscopy and scanning electron microscopy. Although these species ultimately develop erect to ascending growth habits, epicotyl development is limited to the production of a single pair ofleaves located immediately superjacent to and decussate with the cotyledons. The shoot system develops from one or more buds located in the axils of the cotyledons. In all respects, seedling ontogeny is very similar to that of previously studied prostrate species of Chamaesyce. Evidence from seedling ontogeny thus contradicts a hypothesis concerning homologies of plant …
