We hypothesized that moss species follow the known vascular plant growth strategy along the successional gradient in mires (i.e., decrease in production and maximal photosynthesis while succession proceeds). To address this hypothesis, we studied links between the growth and related ecophysiological processes of Sphagnum mosses from a time-since-initiation chronosequence of five wetlands. In agreement with our hypothesis, increase in biomass and CO2 exchange rate of Sphagnum mosses decreased along the successional gradient. Our study divided the species into three groups; pioneer species, hollow species, and ombrotrophic hummock formers. The three groups along the mire successional gradient appeared to be somewhat analogous to the three primary strategies proposed by Grime.
