The two dominant Sphagnum species showed opposing responses when transplanted southward Sphagnum balticum height increment decreased, whereas S. As a result ericoid aboveground biomass in the transplanted mesocosms increased most at the southernmost site, this site also had highest ericoid biomass in the undisturbed vegetation. Four growing seasons after transplantation, ericaceous dwarf shrubs had become much more abundant when transplanted to the warmest site which also had highest N deposition. In addition, we monitored undisturbed vegetation in control plots at the four sites of the latitudinal gradient. We performed a transplantation experiment in which mesocosms with intact vegetation were transplanted southward from north Sweden to north-east Germany along a transect of four bog sites, in which both temperature and N deposition increased. How global warming and increased nitrogen (N) deposition will affect the species composition in bog vegetation is still unclear. In these bogs, peat mosses (Sphagnum) and vascular plants occur in an apparent stable equilibrium, thereby sustaining the carbon sink function of the bog ecosystem. ![]() A large proportion of northern peatlands consists of Sphagnum-dominated ombrotrophic bogs.
