The study uses measured and calculated data on airborne pollutants, particularly nitrogen (ranges between 28 to 43kgN*ha(-1)yr(-1)) and sulphur (10 to 18kgSO(4)-Sha(-1)*yr(-1)), in order to assess their long-term (1992 to 2005) effects on bryophytes at the UN-ECE Integrated Monitoring site 'Zöbelboden' in Austria. Bryophytes were used as reaction indicators on 20 epiphytic plots using the IM monitoring method and on 14 terrestrial plots using standardised photography. The plots were recorded in the years 1992, 1993, 1998, and 2004/2005. Most species remained stable in terms of their overall population size during the observed period, even though there were rapid turnover rates of a large percentage of species on all investigated plots. Only a few bryophytes (Hypnum cupressiforme, Leucodon sciuroides) responded unambiguously to N and S deposition. Nitrogen deposition had a weak but significant effect on the distribution of bryophyte communities. However, the time shifts in bryophyte communities did not depend on total deposition of N and S.
该研究使用了关于空气传播污染物的实测和计算数据，特别是氮（范围在28至43千克氮·公顷⁻¹·年⁻¹之间）和硫（10至18千克硫酸根硫·公顷⁻¹·年⁻¹），以评估它们在1992年至2005年期间对奥地利联合国欧洲经济委员会综合监测站点“策贝尔博登”的苔藓植物的长期影响。苔藓植物被用作反应指标，在20个附生样地采用综合监测方法，在14个陆地样地采用标准化摄影。这些样地在1992年、1993年、1998年以及2004/2005年进行了记录。在观察期内，大多数物种的总体种群规模保持稳定，尽管在所有调查样地上有很大比例的物种更替率很快。只有少数苔藓植物（桧叶金发藓、松鼠尾藓）对氮和硫沉降有明确反应。氮沉降对苔藓植物群落的分布有微弱但显著的影响。然而，苔藓植物群落的时间变化并不取决于氮和硫的总沉降量。
