The predicted long lag time between a decrease in atmospheric deposition and a measured response in vegetation has generally excluded the investigation of vegetation recovery from the impacts of atmospheric deposition. However, policy-makers require

Analysis of changes in functional traits and functional diversity offers a means of identifying the main environmental drivers of change, the impacts of that change on community assembly and the consequence of change on ecosystem function and service

Assessing effectiveness of international biodiversity targets requires long-term monitoring of species to identify changes in their abundance. Grasslands cover large areas of many countries, provide high levels of provisioning ecosystem services and

In alpine ecosystems, nitrogen (N) deposition has been linked to plant community composition change, including loss of bryophytes and increase of graminoids. Since bryophyte growth is stimulated by increased N availability, it has been hypothesized t

Deposition of reactive nitrogen (N) is a major threat to terrestrial ecosystems associated with impacts on ecosystem properties and functions including carbon (C) and nutrient stocks, soil water quality and nutrient retention. In the oceanic-alpine R

Alpine ecosystems are predicted to be severely affected by climate change. Cold, wet oceanic-alpine environments may also accumulate large total ecosystem carbon (C) pools, but have rarely been investigated. We assessed C pools and fluxes on a topose

Two long-term (16 year) experiments on intensively managed pastures compared extensive grazing, abandonment and continued intensive grazing and were assessed for impacts on soil parameters, plant nutrient content and ecological indicator values. Ther

Nitrogen (N) deposition and land management practices can have profound impacts on the structure and functioning of alpine ecosystems occupying headwaters of major river systems. Such impacts have the potential to result in loss of N to surface water

Extensification of grassland management has been put forward as a method of redressing the biodiversity losses seen in agricultural landscapes as a result of increases in production. However, there is little evidence for its success, particularly in

The last few decades have seen an exponential increase in the atmospheric concentration of reactive nitrogen. This has led to concerns from scientists, ecologists, and land managers regarding a cascade of ecosystem impacts, and the potential for elev
