Decoupling of Filtering Equations,to as a sedimentary biogeochemical cycle (Odum, 1959). That is, flux and cycling are affected primarily by hydrologic factors (including dissolution, erosion, and sedimentation), landslides, vulcanism, and biologic agents. The presence of a prominent gaseous component in the biogeochemical cycle (e.

Decoupling of Filtering Equations, small area, 92% of the earth’s plant biomass and 46% of its annual net primary production come from forests (Table 21). The 79.9 billion metric tons of 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 s

Epilog,geochemist. Actually he was a brilliant, yet humble student of nature in the purest sense. Much of what this little book has described in quantitative terms Aldo Leopold outlined in general terms 25 yr ago. His insight and prose have been an inspiration to us for a long time.

Summary Discussion and Conclusions,This book summarizes our current understanding of the biogeochemistry of an undisturbed northern hardwood forest ecosystem at Hubbard Brook. It emphasizes the usefulness of the small watershed technique of biogeochemical measurement in shedding light on ecosystem function.
