Unexpected sudden catastrophic shifts may occur in ecosystems, with concomitant losses or
gains of ecological and economic resources. Such shifts have been theoretically attributed …

Methane (CH4) is the most abundant organic trace gas in the atmosphere. In the distant
past, variations in natural sources of methane were responsible for trends in atmospheric …

Peatlands form important landscape elements in many parts of the world and play significant
roles for biodiversity and global carbon balance. This new edition has been fully revised and …

Peatlands occupy a relatively small fraction of the Earth's land area, but they are a globally
important carbon store because of their high carbon density. Undisturbed peatlands are …

This book is divided into four parts that look in turn at the nature of peatland classification
and terminology, hydrological and ecological processes and peatland growth, changes in …

Equations based on empirical relationships of peat physical properties were used to
estimate the average long-term apparent rate of carbon accumulation (LORCA) in Finnish …

Northern peatlands contain up to 25% of the world's soil carbon (C) and have an estimated
annual exchange of CO2‐C with the atmosphere of 0.1–0.5 Pg yr− 1 and of CH4‐C of 10–25 …

Peatlands cover over 400 million hectares of the Earth's surface and store between one-third
and one-half of the world's soil carbon pool. The long-term ability of peatlands to absorb …

Ongoing climate change is modifying climatic conditions worldwide, with a trend towards
drier conditions in most regions. Vegetation will respond to these changes, eventually …

Throughout the Holocene, northern peatlands have both accumulated carbon and emitted
methane. Their impact on climate radiative forcing has been the net of cooling (persistent …
