- 1. Bryophytes in the Arctic and Alpine regions are important in terms of biodiversity, cover and biomass. However, climate change and widespread shrubification of alpine and arctic tundra is predicted to increase in the future, with potentially large impacts on bryophyte communities.2. We studies the impact of 18 years of experimental warming with open top chambers (OTCs) on bryophyte cover, richness and diversity in an alpine mesic meadow and a heath plant community in Northern Sweden. In addition we investigated the relationship between deciduous shrubs and bryophytes.3. Cover and richness of bryophytes both declined due to long-term warming, while diversity did not show any significant responses. After 18 years, bryophyte cover had decreased by 71% and 26 in the heath and meadow, while richness declined by 39% and 26%, respectively.4. Synthesis. Decline in total bryophyte cover in both communities in response to long-term warming was driven by a general decline in many species, with only two individual species showing significant declines. Although most of the species included in the individual analyses did not show any detectable changes, the cumulative change in all species was significant. In addition, species loss was slower than the general decline in bryophyte abundance. As hypothesized, we found significant negative relationship between deciduous shrub cover and bryophyte cover, but not bryophyte richness, in both plant communities. This is likely due to a more delayed decline in species richness compared to abundance, similar to what was observed in response to long-term warming.
