Disagreements on how fens and bogs are defined warrants an evaluation of how researchers classify these habitats. Ongoing work with a new typology for ecosystems creates an urgency to understand the classification in the field. The aim of this meta-study was to assess authors' naming of fen and bogs habitats, with regards to pH and indicator specie...
Deponeringar under bronsåldern är ett fenomen som uppstod både på land och i olika formerav vattentillstånd som till exempel sjöar, våtmarker, floder och vattenfall. Mycket forskninghar gjorts inom det här området, kring vilka typer av fynd och föremål som har hittats i dessasammanhang och många frågor uppstår när man arbetar med deponeringar som e...
Northern peatlands, which are crucial reservoirs of carbon and nitrogen (415 ± 150 and 10 ± 7 Pg, respectively), are vulnerable to microbial mineralization after permafrost thaw. This study was carried out in four key sites containing northern permafrost peatland, which are located along the southern cryolithozone. The aim of this study is to chara...
As they are not only the home of many threatened species, but also one of the main actors in the global carbon cycle, peatlands are highly valuable ecosystems. Human disturbance, in particular drainage for forestry and agriculture, has substantially changed the state of the world’s peatlands and will continue to do so. Lowering the water table by d...
Based on the data of the plant macrofossil and palynological composition of the peat deposits, the evolution and current state of polygonal peatlands were analyzed at the southern limit of continuous permafrost in the Pur-Taz interfluve. Paleoreconstruction shows that peat accumulation began in the Early Holocene, about 9814 cal. year BP, in the La...

Methane (CH4 ) emissions from northern peatlands are projected to increase due to climate change, primarily because of projected increases in soil temperature. Yet, the rates and temperature responses of the two CH4 emission-related microbial processes (CH4 production by methanogens and oxidation by methanotrophs) are poorly known. Further, peatlan...

Peat layers are well represented in the Holocene coastal deposits of the southern North Sea and provide evidence as to the extent and nature of the fens and bogs that occupied the region in the mid and late Holocene. While natural processes contributed to their demise, without human interference extensive areas of peatland would remain. We review t...

AbstractFor the first time, the ratio of large taxa and the genera spectrum of the prokaryotic community of the rhizosphere soil under typical plants of bogs were studied using high-throughput sequencing. The predominance of Acidobacteria and Alpha-proteobacteria and a low proportion of other taxa (less than 10%) were established. Representatives o...
Freshwaters of northern Chilean Andes include many bogs referred to as “bofedales”. streams of snowmelt origin feed these endorheic water bodies at high altitudes in the arid mountain zone. Our knowledge of biota inhabiting these ecosystems is rudimentary due to their marked geographical isolation. The present study aimed to do a first characteriza...

AbstractCurrently, the taxonomy of peat soils is not given more attention, especially with regard to taxonomic units in the species rank. The diagnostics of 51 soil profiles in the various oligotrophic mire types in the Numto Nature Park (north taiga subzone of West Siberia) has brought about proposals to improve the existing soil classification. I...
