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.

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 long-term data on precipitation and streamwater chemistry, hydrology and weathering, and also considers the dynamics of atmospheric gases and water as they flow through the system. Hailed as " a standard for ecological teaching and research for years to come," the book "bristles with unsettled questions, intriguing problems, and technical challenges." This new edition brings the 1977 volume up to date and presents the ongoing Hubbard Brook study to a new generation of ecologists. The authors have international reputations: they won the $150,000 Tyler Prize in Environmental Science in 1993, and Likens also won the $250,000 Australia Prize in 1994.
