Nutrients, light, and temperature
This chapter discusses how nutrients, light, and temperature vary within and among peatland types. The chemical and biological processes that govern the circulation and availability of nitrogen are presented. The effects of nutrient limitations for plant growth and species composition are also discussed for other elements, such as potassium and phosphorus. The variation in light is presented, and distinctions are made between plants adapted to open sites and forest-shaded species. Temperature and moisture regimes are key climatic factors explaining the rates of peat accumulation and decomposition, and the global distribution of peatlands. Climates are described at three spatial scales from the regional macroclimate, via the mesoclimate of a particular peatland to the microclimatic variation; for instance, the temperature variation between hummocks and hollows.
