The effects of increased nitrogen influx on Sphagnum growth and on interspecific
competition between Sphagnum species were studied in a 3-yr experiment in mires situated …

Many chemical reactions at the Earth's surface are influenced by biota. Ecosystem
ecologists study the flow of matter and energy in ecosystems composed of organisms and …

Across Europe, total nitrogen deposition is increasing and, of this total, atmospheric
ammonia can contribute up to 50–80%. Average deposition of ammonia in the UK is likely to …

Recent and long‐term accumulation rates of carbon (C), using 210Pb‐and 14C‐dating,
were examined in 23 ombrotrophic peatlands in eastern Canada, where average 1990 …

The critical load concept is used to establish the deposition levels which ecosystems can
tolerate without significant harmful effects. Here we summarize work within the Swedish …

• We studied the effects of increasing levels of atmospheric nitrogen (N) deposition on
nutrient limitation of ombrotrophic Sphagnum plants.• Fifteen mires in 11 European countries …

Alteration of the global nitrogen (N) cycle because of human‐enhanced N fixation is a major
concern particularly for those ecosystems that are nutrient poor by nature. Because …

Sphagnum mosses are considered peatland engineers because of their ability to create
conditions inducing carbon accumulation. Here, we report on a review of the effects of four …

Nitrogen (N) deposition may affect litter decomposition and may thus have an impact on the
rate of carbon (C) sequestration in Sphagnum peatlands. We present results from four …

Summary 1 In order to test whether the observed invasion of ombrotrophic bogs in the
Netherlands by Molinia caerulea and Betula pubescens is the result of long‐term high …
