The effects of air‐borne nitrogen pollutants on species diversity in natural and semi‐natural European vegetation
Summary The effects of increased atmospheric nitrogen inputs, from both NOy and NHx, on diversity in various semi-natural and natural ecosystems are reviewed. The severity of these impactsExpand
Natural nitrogen filter fails in polluted raised bogs
Summary Raised bogs are among the ecosystems most susceptible to atmospheric nitrogen pollution. Based on global data ranging from pristine to heavily polluted areas, a conceptual model is presentedExpand
Internal eutrophication: How it works and what to do about it—a review
In the 1980s and 1990s, it became increasingly clear that changes in external nutrient loads alone could not entirely explain the severe eutrophication of surface waters in the Netherlands. Nowadays,Expand
Sulfate-Induced Eutrophication and Phytotoxicity in Freshwater Wetlands
In recent decades, sulfate concentrations in many European freshwater wetlands have increased by 10-fold or more, due mainly to the use of sulfate-polluted river water to compensate for waterExpand
Methanotrophic symbionts provide carbon for photosynthesis in peat bogs
TLDR
The symbiosis between Sphagnum mosses and partly endophytic methanotrophic bacteria explains both the efficient recycling of methane and the high organic carbon burial in these wetland ecosystems. Expand
Stimulated growth of Betula pubescens and Molinia caerulea on ombrotrophic bogs: role of high levels of atmospheric nitrogen deposition
TLDR
Evidence is provided that the observed dominance of Molinia on ombrotrophic bogs in the Netherlands is caused by high N deposition levels, and it is assumed that a long-term deposition of 0.5 g N m−2 year−1, or higher, leads to undesirable changes in species composition and increased risk of desiccation.

Ammonium toxicity in eelgrass Zostera marina
Seagrasses are declining all over the world, resulting in a substantial loss of biodiversity, coastal sediment stabilization and nursery areas of economically important fish. The seagrass decline hasExpand
IMPACT OF ACIDIFICATION AND EUTROPHICATION ON MACROPHYTE COMMUNITIES IN SOFT WATERS IN THE NETHERLANDS I. FIELD OBSERVATIONS
During the last decades a strong decline has been noticed in the number of waters dominated by “Littorellion” species, mostly isoetids such as Lobelia dortmanna L., Isoetes lacustris L. andExpand
Inlet of alkaline river water into peaty lowlands: effects on water quality and Stratiotes aloides L. stands
Abstract As a result of changed land use and concomitantly increased drainage, in combination with increased use of water for industrial, agricultural and other human purposes, there is an increasingExpand
Expansion of invasive species on ombrotrophic bogs: desiccation or high N deposition?
TLDR
The invasion of bogs by Molinia and Betula is likely to be less affected by desiccation than by increased N availability, and apparently, Molinia is well adapted to P-limiting conditions, which may explain its success in regions with increased N deposition levels. Expand
