This is often the 1st actually ecosystem-oriented ebook on peatlands. It adopts an ecosystems method of realizing the world's boreal peatlands. the focal point is on biogeochemical styles and approaches, creation, decomposition, and peat accumulation, and it presents more information on animal and fungal variety. A routine subject matter is the legacy of boreal peatlands as awesome accumulators of carbon as peat over millennia.

Communities with eutrophic nutrient status are restricted to non-peat-forming wetlands (marshes and southern swamps). This oligotrophic–eutrophic nutrient gradient is independent of the “mineral” gradient composed of pH, base cations (Na+, K+, Ca2+, Mg2+), and associated anions (HCO3–, CO32–, SO42–, Cl–) (Vitt and Chee 1990). The formation of peat and the differentiation of various bog and fen types occurs along this mineral gradient (see Fig. 1 in Vitt 2002). 0, while concentrations of total base cations vary from nearly zero to more than 1,000 mg L–1.
Subarctic peatlands are included because they mostly originated under “boreal” conditions during the Holocene Hypsithermal (Ritchie 1976; Kremenetski et al. 1998). , peat accumulation, acidification) factors. Ecological Studies, Vol. ) Boreal Peatland Ecosystems © Springer-Verlag Berlin Heidelberg 2006 26 P. Kuhry and J. 2 Study Area On a global scale, the occurrence of peatlands is strongly related to topography and climate, with the greatest abundance found on flat land areas of cool and moist climates (Sjörs 1959; Walter 1977; Botch and Masing 1983; Ovenden 1990; Riley 1994; Botch et al.
Discrimination between individual factors is often very difficult. , hummocks and hollows of raised bogs, strings and flarks of aapa mires, peat plateaus and thermokarst ponds), and each site can have its own specific developmental history. Therefore, large numbers of peatlands (if possible, each with numerous coring sites) are needed to study regional patterns in peatland development. Unfortunately, systematic studies with equidistant (or random) coring in peatland complexes are rare. Paleoecologists tend to focus on the deepest parts of peat areas to obtain the longest possible records; collection sites are often near communication arteries such as (rail-) roads or rivers and not in the central parts of vast peatland complexes; detailed inventories for peat mining, available especially from Russia, avoid the shallower marginal areas of peatland complexes, which are not considered economically significant.
