Recent research on the organo-chemical composition of Sphagnum and on the fate of its litter has further clarified how this plant builds acidic, nutrient-poor, cold and anoxic peat bogs. The bog environment helps Sphagnum to outcompete other plants for light. Its morphology, anatomy, physiology and composition make it an effective ecosystem engineer and at the same time benefit the plant in the...

The (13)C (12)C isotope ratios and the leaf anatomy of 18 species and varieties of Euphorbia native to the Hawaian Islands indicated that all possess C(4) photosynthesis. These species range from small prostrate coastal strand shrubs to shrubs and trees in rainforest and bog habitats. The results show that C(4) photosynthesis occurs in plants from a much wider range of habitats and life-forms t...

The increase in the frequency of peatland fires is due to both global climate change and deliberate human activity. primary aim study was investigate structure microbial communities nematodes before after a peat bog fire, as well analyse relationships between food web components. Hydrological physicochemical parameters were analysed during period fire (2018 2019) (2020 2021—2, 4, 8, 12 months f...

Afforestation is a significant cause of global peatland degradation. In some regions, afforested bogs are now undergoing clear-felling and restoration, often known as forest-to-bog restoration. We studied differences in water-table depth (WTD) porewater chemistry between intact, afforested, restored at raised bog blanket location. Solute concentrations principal component analysis suggested tha...

Abstract We measured stable isotopes (δ 18 O and δ 13 C) in Sphagnum cellulose that was extracted from a long peat core drilled the ombrotrophic Mohos bog, Ciomadul Mountain, Romania. The 10-m-long profile spans period 11,800 cal yr BP to present. C data indicate there were several cooling events warm periods area of bog during Holocene. 8.2-ka cold event, however, not detected using values. Re...

The response of methanogens to thawing permafrost is an important factor for the global greenhouse gas budget. We tracked methanogenic community structure, activity, and abundance along the degradation of sub-Arctic palsa peatland permafrost. We observed the development of pronounced methane production, release, and abundance of functional (mcrA) methanogenic gene numbers following the transiti...

High current densities in microbial electrolysis cells (MECs) result from the predominance of various Geobacter species on the anode, but it is not known if archaeal communities similarly converge to one specific genus. MECs were examined here on the basis of maximum methane production and current density relative to the inoculum community structure. We used anaerobic digester (AD) sludge domin...
