The BIOGEOMON conference, held in Prague, September 1993, was dedicated to the use of geochemistry and biology in the elucidation of biogeochemical processes in the context of research on small catchments, which are natural systems that lend themselves to the study of environmental problems at the ecosystem level. This text, which contains reviewed papers from the conference, includes long-term studies of nutrient cycling in forested catchments, effects of anthropogenic action on streamwater chemistry, stable isotope studies for tracing biogeochemical processes, determination of the process rates and mathematical modelling of ecosystem behaviour and mass fluxes. This book is intended for research scientists and students of ecology, biology, hydrology and geochemistry as well as professionals in natural resources management.

This volume contains reviewed papers from BIOGEOMON, The Third International Symposium on Ecosystem Behaviour, held at Villanova University in June 1997 and attended by over 240 participants from 28 countries. Earlier BIOGEOMON meetings emphasized mostly geochemical research conducted in small watersheds. As is evident from this collection of papers, BIOGEOMON has broadened its scope considerably to include research conducted in much larger watersheds, often assessing landscape or regional patterns and processes. Major themes include acidification of soils and waters, biogeochemical implications of nitrogen and sulfur deposition, and gas fluxes from the land to the atmosphere. Collectively, the papers in this volume present a variety of approaches to biogeochemical research at the ecosystem level, including monitoring, field and laboratory manipulations, stable and radioisotopic tracers, modelling, and geographic information system analysis. This book should be of interest to researchers in biogeochemistry, ecosystem ecology, global change, and anthropogenic pollution, as well as to natural resource managers and policy specialists.

This volume contains reviewed papers from BIOGEOMON, The Fourth International Symposium on Ecosystem Behavior, held at the University of Reading in August 2002, and attended by over 260 participants from 25 countries. The papers in this volume focus on themes that have always been strong at BIOGEOMON, such as: Beyond these traditionally emphasized themes, other papers focus on: Audience: This book will be of interest to researchers in biogeochemistry, ecosystem ecology, global change, and anthropogenic pollution, as well as to natural resource managers and policy specialists.

Fifteen years have passed since a small group of researchers at the Czech Geo­ logical Survey boldly convened a conference called GEOMON, Geochemical Monitoring in Representative Basins, held in Prague in 1987. The focus of the original GEOMON conference was rather narrow - monitoring of element pools and fluxes on a small catchment scale. Signaling a desire to broaden the focus to a more biogeochemical orientation, the 1993 meeting, also in Prague, was renamed BIOGEOMON. Tofoster wider international participation and cooperation, in 1997 BIOGEOMON was held at Villanova University in Pennsylvania. The most recent iteration of BIOGEOMON was held at the University of Reading in the United BIOGEOMON meetings to date. At Kingdom and was the largest of the series of Reading, BIOGEOMON hosted 43 invited speakers, 96 contributed talks and over 150 poster presentations. Over 260 delegates came to Reading inAugust 2002 from 25 countries around the world. At Reading, themes that always have been strong at BIOGEOMON were con­ tinued: catchment monitoring and manipulations, catchment and regional-scale modeling, nitrogen transformations and processes, and stable and radiogenic iso­ topes in the environment. Beyond these traditionally emphasized themes, other sessions focused on mercury and metal dynamics, phosphorus, scaling of biogeo­ chemical processes, terrestrial DOC and soil organic matter, rhizosphere biogeo­ chemistry, biogeochemistry of restored ecosystems, and archives of global change on the continents. Most of these themes are represented in this Special Issue, a collection of peer-reviewed articles.
