Reactive nitrogen (N) and ozone (O3) are the most widespread atmospheric pollutants with significant implications for conservation of semi-natural vegetation; their combined effects have, however, not been tested in long-term field experiments. To investigate these effects on the species composition of a subalpine Geo-Montani-Nardetum pasture, 180 turf monoliths were exposed for seven years to five N loads (0, +5, +10, +25, +50 kg N ha−1 y−1) in combination with three O3 levels (ambient, 1.2 or… 
Ozone and Nitrogen Effects on Juvenile Subalpine Plants: Complex Interactions with Species and Colonization by Arbuscular Mycorrhizal Fungi (AMF)
TLDR
The results indicate that irrespective of AMF colonization, juvenile plants are highly sensitive to O3 stress, probably since their growth is primarily limited by carbon assimilation.
Cumulative and partially recoverable impacts of nitrogen addition on a temperate steppe.
TLDR
The findings suggest serious and cumulative impacts of N addition on plant and soil communities but the potential for partial system recovery over time if N inputs decline or cease.
Ozone impacts on vegetation in a nitrogen enriched and changing climate.
Plant responses to long term elevated ozone in a British upland semi-natural grassland
A novel free-air gas concentration enrichment (FACE) experiment exposed a species rich semi-natural upland grassland to ozone at average levels of ambient + 75 ppb, + 25 ppb and + 15 ppb over a 6
Foliar uptake of atmospheric nitrate by two dominant subalpine plants: insights from in situ triple-isotope analysis.
TLDR
It is confirmed that foliar uptake is a potentially important pathway for NO3 - atm into subalpine plants, of major significance as N emissions (and deposition) are predicted to increase globally in the future.
Subalpine grassland productivity increased with warmer and drier conditions, but not with higher N deposition, in an altitudinal transplantation experiment
Abstract. Multiple global change drivers affect plant productivity of grasslands and thus ecosystem services like forage production and the soil carbon sink. Subalpine grasslands seem particularly

Nitrogen deposition but not ozone affects productivity and community composition of subalpine grassland after 3 yr of treatment.
TLDR
Results suggest that effects of elevated O(3) on the productivity and floristic composition of subalpine grassland may develop slowly, regardless of the sensitive response to increasing N.
Different types of sub‐alpine grassland respond similarly to elevated nitrogen deposition in terms of productivity and sedge abundance
TLDR
The response of sub-alpine grassland to elevated N deposition can be ranked as universal both for Seslerietum as well asacidic Nardetum pastures and thus can be considered universal for both productivity and nutrient availability.
Subalpine grassland carbon dioxide fluxes indicate substantial carbon losses under increased nitrogen deposition, but not at elevated ozone concentration
Ozone (O3) and nitrogen (N) deposition affect plant carbon (C) dynamics and may change ecosystem C‐sink/‐source properties. We studied effects of increased background [O3] (up to [ambient] × 2) and
Loss of plant species after chronic low-level nitrogen deposition to prairie grasslands
TLDR
Results of the first multi-decadal experiment to examine the impacts of chronic, experimental nitrogen addition as low as 10 kg N ha-1 yr-1 above ambient atmospheric nitrogen deposition find that this chronic low-level nitrogen addition rate reduced plant species numbers by 17% relative to controls receiving ambient N deposition.

TLDR
Elevated ozone concentrations may be a significant barrier to achieving increased species diversity in managed grasslands, as measured in an upland mesotrophic grassland located in the UK.
Cumulative nitrogen input drives species loss in terrestrial ecosystems
Aim  Elevated inputs of biologically reactive nitrogen (N) are considered to be one of the most substantial threats to biodiversity in terrestrial ecosystems. Several attempts have been made to
Nitrogen critical loads for alpine vegetation and terrestrial ecosystem response: are we there yet?
TLDR
Changes in vegetation composition will precede detectable changes in more traditionally used soil indicators of ecosystem responses to N deposition and that changes in species composition are probably ongoing in alpine dry meadows of the Front Range of the Colorado Rocky Mountains.
