The natural carbon storage function of peatland ecosystems can be severely affected by the abandonment of peat extraction, influencing peatland drainage, leading to large and persistent sources of atmospheric CO2. Moreover, these cutover peatlands have a low and variable water table position and high tension at the surface, creating harsh ecohydrological conditions for vegetation re-establishme...

the present paper investigates the influence of stabilization with cement, peat ash, and silica sand on permeability coefficient (kv) of compacted clay, using a novel approach to stabilize the clay with peat ash as a supplementary material of cement in the compacted and stabilized soil. in order to assess the mentioned influence, test specimens of both untreated and stabilized soil have been te...

Fully grown broth cultures of various fast- and slow-growing rhizobia were deliberately diluted with various diluents before their aseptic incorporation into autoclaved peat in polypropylene bags (aseptic method) or mixed with the peat autoclaved in trays (tray method). In a factorial experiment with the aseptic method, autoclaved and irradiated peat samples from five countries were used to pre...

Throughout their 420-Ma-long history, Lycopodiopsida have played a subordinate role at the landscape level with very few exceptions. One being arborescent Lepidodendrales that dominated Pennsylvanian peat swamps in equatorial regions. Another is enigmatic world-wide proliferation of sub-arborescent Isoëtales during, and aftermath Permo-Triassic terrestrial biosphere crisis extended deep into Tr...

The global climate change and significantly increased anthropogenic pressure on the Arctic Subarctic regions require modern ecosystem monitoring understanding of past environmental changes. Vegetation history is reflected by pollen spectra recorded in peat deposits, investigation which one main methods research long-term climatic In order to reconstruct vegetation fire today’s south tundra lowe...

In the Hudson Bay/James Bay Lowlands, along the coasts of Banks Island, and along the eastern coast of Baffin Island are continuous and extensive sections in Quaternary sediments. These sections are rich in marine fossils, buried peats, and soils and contain a wide variety of glaciagenic sediments together with glacial marine units and littoral deposits. Lake muds are also fairly common. All th...

Tropical peat swamp lands in the Southeast Asia which store tremendous large amount of carbon in their peat layer and abundant biodiversity are now endangered by human activities such as deforestation, forest fires, land development and urbanization. To earlier start a better environmental policy for conservation of nature of the tropical peat swamp area is one of the preferential global issues...

The use of the phospholipid fatty acid (PLFA) composition of microorganisms to detect previous self-heating events was studied in naturally self-heated peat and in peat incubated under temperature-controlled conditions. An increased content of total PLFAs was found in self-heated peat compared to that in unheated peat. Two PLFAs, denoted T1 and T2, were detected only in the self-heated peat. In...

A partially peat-extracted coastal bog contaminated by seawater was barren and required revegetation as a wetland. Peat fields were rectangular in shape, cambered in cross-section profile, and separated by drainage ditches. Common to all peat fields were symmetrical patterns in micro-topography with slopes between differences in elevation. Saline non-waterlogged slopes of ∼5% occurred as a symm...
