Ecosystem Analysis -- Hydrology -- Chemistry -- Input-Output Budgets -- Weathering -- Nutrient Cycles -- The Northern Hardwood Ecosystem at Hubbard Brook in Relation to Other Forest Ecosystems Conclusion. Based on the classic ecosystem studies at Hubbard Brook in New Hampshire, this book presents an in-depth analysis of the biogeochemistry of a terrestrial ecosystem. It synthesizes more than 30 years of data on precipitation and stream-water chemistry, hydrology, and weathering, and also considers the role of atmospheric gases and water as they flow through the system. The book illustrates ways in which ecosystems are affected by the three major biogeochemical vectors of the Earth: air, water, and animals. In turn, it shows how an ecosystem moderates and changes inputs, and how it is connected to global biogeochemical cycles by its outputs.
