The biological fixation of atmospheric nitrogen (N) is a major pathway for available N
entering ecosystems. In N-limited boreal forests, a significant amount of N2 is fixed by …

Human activity in the last century has led to a significant increase in nitrogen (N) emissions
and atmospheric deposition. This N deposition has reached a level that has caused or is …

Increasing rates of atmospheric nitrogen (N) deposition may reduce growth and accelerate
decomposition of Sphagnum mosses in bogs. Sphagnum growth and rates of Sphagnum …

Data from 55 published studies of Sphagnum productivity were compiled covering 31 peat-
moss species from Sphagnum-dominated wetlands. The relationships between productivity …

Summary 1 In many ombrotrophic bog areas the invasion of grass (eg Molinia caerulea) and
tree (eg Betula pubescens) species has become a major problem. We investigated whether …

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 …

Biodiversity has been described as the diversity of life on earth within species, among
species, and among ecosystems. The rate of biodiversity loss due to human activity in the …

It is nearly impossible to describe the relative importance of the inputs and outputs of
nitrogen (N) to peatlands without first distinguishing among peatland types. As discussed in …

Peat forming Sphagnum mosses are able to prevent the dominance of vascular plants under
ombrotrophic conditions by efficiently scavenging atmospherically deposited nitrogen (N). N …

Aims Slow decomposition and isolation from groundwater mean that ombrotrophic
peatlands store a large amount of soil carbon (C) but have low availability of nitrogen (N) …
