Biogeochemistry of a Forested Ecosystem

Abstract

The first in a series of 3 volumes on a 15-yr ecosystem study of an undisturbed, second-growth northern hardwood forest at Hubbard Brook, New Hampshire [see FA 36, 1946, 4576], dealing specifically with the area's biogeochemistry. The contents are: Ecosystem analysis; Hydrology; Chemistry; Input-output budgets; Weathering; Nutrient cycles; The northern hardwood ecosystem at Hubbard Brook in relation to other forested ecosystems in the world; and Summary, discussion and conclusions. The impervious bedrock of this catchment area, consisting of highly metamorphosed sediments, prevents unaccounted losses of material from the ecosystem by deep seepage.
