Repeated fires in forested peatlands in sporadic permafrost zone in Western Canada
Wildfires play a crucial role in northern boreal peatland ecosystems, influencing the functioning of these ecosystems by affecting vegetation composition and biomass, peat accumulation patterns, and soil carbon stocks. Northern peatland ecosystems are under pressure due to climate warming and increasing anthropogenic stress. The frequency and severity of wildfires is predicted to increase in the coming years. Therefore, understanding long-term na…
Appraising the cohesion of palaeoenvironmental reconstructions in north-west Spain since the mid-Holocene from a high temporal resolution multi-proxy peat record
Investigation of abrupt palaeohydrological regime change remains challenging due to site-specific noise ratios and the limitations of dating control and spatial resolution of multi-proxy records. Some of these issues are addressed through a well dated and highly resolved record from an ombrotrophic peatland in Galicia, north-west Spain. The site is in an ideal location to record marine influences and test models of past palaeoclimatic boundaries …
A database and synthesis of northern peatland soil properties and Holocene carbon and nitrogen accumulation
Here, we present results from the most comprehensive compilation of Holocene peat soil properties with associated carbon and nitrogen accumulation rates for northern peatlands. Our database consists of 268 peat cores from 215 sites located north of 45°N. It encompasses regions within which peat carbon data have only recently become available, such as the West Siberia Lowlands, the Hudson Bay Lowlands, Kamchatka in Far East Russia, and the Tibetan…
Stable isotopes in Sphagnum fuscum peat as late-Holocene climate proxies in northeastern European Russia
The environment of the northern taiga to tundra transition is highly sensitive to climate fluctuations. In this study from northeastern European Russia, stable carbon and oxygen isotope ratios (δ 13 C, δ 18 O) in α-cellulose of Sphagnum fuscum stems subsampled from hummocks and peat plateau profiles have been used as climate proxies. The entire isotope time series, dated by lead ( 210 Pb), caesium ( 137 Cs) and AMS-radiocarbon ( 14 C) dating, spa…
A 1000-year reconstruction of summer precipitation from Ireland
Holocene development of the Rogovaya River peat plateau, European Russian Arctic
In this study, the Holocene development of a peat plateau area in the east-European Russian Arctic is reconstructed based on detailed macrofossil, physico-chemical and radiocarbon analyses from two peat sequences. Basal dates from these two, c. 2 m long, peat profiles are c. 9420 BP and c. 9250 BP. From another six peat sequences gross-stratigraphic descriptions and additional radiocarbon dates are available. Basal dates from two short (<1 m) pea…
