闡明

The Northern Hardwood Ecosystem at Hubbard Brook in Relation to Other Forest Ecosystems in the Worl dry plant matter produced (net) each year by forests exceeds the total net primary production of the oceans, even though the oceans are more than six times larger in area. The animal biomass in these forests represents 68% of the total found on continental land masses (Whittaker and Likens, 1973).

Weathering, to a lesser extent by chlorides and bicarbonates. This qualitative change in chemistry exemplifies the general chemical weathering reactions. This reaction and some of the chemical pathways in an open system, such as the Hubbard Brook watershed ecosystem, are shown in Figure 40.

BROTH

Book 19952nd editionars, and we included data through 1974, or a biogeo- chemical record of 11 years. Now our continuous, long-term biogeo- chemical records cover more than 31 years, and there have been many changes. The most notable change, however, is that three of our coauthors on the original volume are now decease

Book 19952nd edition introductory study of, or course in, biogeochemistry. Our goal in this revision is to preserve these fea- tures, correct errors, and revise or eliminate misleading or ambiguous short-term data (11 years!), while maintaining approximately the original length and the modest cost.
