The origin of alkaline fen in the Mosbeek Valley in the Netherlands is due to human impact rather than a natural development
Alkaline fens are important Natura 2000 habitats, which harbor many endangered plant species. Alkaline fens are formed in areas with groundwater discharge and usually developed in a natural way in the early Holocene. We radiocarbon dated the base of three peat deposits from spring fens along the flanks of the ice-pushed ridge near the village of Ootmarsum to find out when and why peat-forming vegetation started to grow. We cored a sequence in the…
A multi-proxy reconstruction of peatland development and regional vegetation changes in subarctic NE Fennoscandia (the Republic of Karelia, Russia) during the Holocene
A better understanding of past long-term environmental changes in the subarctic region is crucial for mitigation of the possible negative effects of climate warming in this vulnerable region. This study provides a new multi-proxy reconstruction of regional vegetation changes and peatland development for north-eastern Fennoscandia (Russia) during most of the Holocene. To that purpose, we performed plant macrofossil, pollen, testate amoebae, peat h…
Contemporary carbon fluxes do not reflect the long-term carbon balance for an Atlantic blanket bog
Peatlands are one of the largest terrestrial stores of carbon. Carbon exchange in peatlands is often assessed solely by measurement of contemporary fluxes; however, these fluxes frequently indicate a much stronger sink strength than that measured by the rate of C accumulation in the peat profile over longer timescales. Here we compare profile-based measurements of C accumulation with the published net ecosystem C balance for the largest peatland …
Late-Holocene climate dynamics recorded in the peat bogs of Tierra del Fuego, South America
The ombrotrophic peat bogs of Tierra del Fuego are located within the southern westerly wind belt (SWWB), which dominates climate variability in this region. We have reconstructed late-Holocene water-table depths from three peat bogs and aimed to relate these records to shifts in regional climate. Water-table depths were quantified by the analysis of testate amoeba assemblages, and a regional transfer function was used to infer past water-table d…
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…
The ‘Little Ice Age’ in the Southern Hemisphere in the context of the last 3000 years
The so-called ‘Little Ice Age’ (LIA) of the 15th to 19th centuries ad is well-attested from much of Europe and from some other parts of the Northern Hemisphere. It has been attributed to solar forcing, associated with reduced solar activity, notably during the Spörer, Maunder and Dalton solar minima, although other causes have also been proposed and feature strongly in recent papers. Detection of the LIA in some proxy-climate records from the Sou…

The disappearance of Sphagnum imbricatum from Butterburn Flow, UK
We welcome the comments by Bjorn Robroek et al. ( The Holocene 19 (2009) 1093—1094, this issue) on our paper (McClymont et al., The Holocene 18 (2008) 991-1002) and the opportunity to discuss further the complexities that surround the disappearance of Sphagnum imbricatum from Butterburn Flow (our study), and the implications for understanding the disappearance of this species in northwest Europe. We also wish to clarify our site of study; we pres…
Multiproxy evidence of `Little Ice Age' palaeoenvironmental changes in a peat bog from northern Poland
`Little Ice Age' (LIA) climatic deteriorations have been abundantly documented in various archives such as ice, lake sediments and peat bog deposits. Palaeoecological analyses of peat samples have identified these climatic deteriorations using a range of techniques, for example palynology, plant macrofossils, testate amoebae or carbon isotopic analyses. The use of inorganic geochemistry and the reconstruction of dust fluxes has remained a challen…
High resolution paleoenvironmental and chronological investigations of Norse landnám at Tasiusaq, Eastern Settlement, Greenland
High-resolution paleoenvironmental data from a peat profile with a small pollen source area are used to reconstruct the impacts of landnám on vegetation and soils at a Norse farm complex (∅2 at Tasiusaq) comprising two farms in the Eastern Settlement of Greenland. Analyses include the AMS 14 C dating of plant macrofossil samples and the use of Bayesian radiocarbon calibration to construct improved age–depth models for Norse cultural horizons. The…
The disappearance of Sphagnum imbricatum from Butterburn Flow, UK
The disappearance of the previously abundant moss species Sphagnum imbricatum has been investigated at Butterburn Flow, northern England, using organic geochemical, elemental, macrofossil, pollen and testate amoebae analyses. Variations in the assemblage of peat-forming plants were tracked using the macrofossil distributions as well as the relative chain lengths of n-alkanes and concentrations of 5- n-alkylresorcinols and triterpenols. No signifi…
Testing the timing of radiocarbon-dated events between proxy archives
For interpreting past changes on a regional or global scale, the timings of proxy-inferred events are usually aligned with data from other locations. However, too often chronological uncertainties are ignored in proxy diagrams and multisite comparisons, making it possible for researchers to fall into the trap of sucking separate events into one illusionary event (or vice versa). Here we largely solve this ‘suck in and smear syndrome’ for radiocar…
Mid- to late-Holocene vegetation and land-use history in the Hadrian's Wall region of northern England
Pollen analyses of a peat profile collected from Butterburn Flow, northern England have been used to reconstruct vegetation and land-use change from the late Neolithic ( c. 3230 cal. BC) to the present day. `Wiggle-matching' of 42 AMS 14 C dates has enabled a precise (decadal scale) chronology to be established, and the results are interpreted within the context of previous studies of vegetation change in the area. Three late Neolithic—Bronze Age…
Tephra-dated climate-and human-impact studies during the last 1500 years from a raised bog in central Ireland
Historic Icelandic tephrochronology constrains the time frame of a plant macrofossil and palynological study of ombrotrophic peat to evaluate the effects of climatic and human impact over the last 1500 years on the landscape at a large monastic site in the Irish Midlands. The plant macrofossil climate proxy record indicates maximum wetness during the sixth century AD. Decreasing wetness occurred from the late ninth century to the late thirteenth …
Late Holocene climatic changes in Tierra del Fuego based on multiproxy analyses of peat deposits.
A ca. 1400-yr record from a raised bog in Isla Grande, Tierra del Fuego, Argentina, registers climate fluctuations, including a Medieval Warm Period, although evidence for the ‘Little Ice Age’ is less clear. Changes in temperature and/or precipitation were inferred from plant macrofossils, pollen, fungal spores, testate amebae, and peat humification. The chronology was established using a 14 C wiggle-matching technique that provides improved age …
Changes in solar activity and Holocene climatic shifts derived from 14C wiggle-match dated peat deposits
Closely spaced sequences of accelerator mass spectrometer (AMS) 14 C dates of peat deposits display century-scale wiggles which can be fitted to the radiocarbon calibration curve. By wiggle-matching such sequences, high-precision calendar age chronologies can be generated which show that changes in mire surface wetness during the Bronze Age/Iron Age transition (c. 850 cal. BC) and the ‘Little Ice Age’ (Wolf, Spörer, Maunder and Dalton Minima) occ…
Evidence from northwest European bogs shows ‘Little Ice Age’ climatic changes driven by variations in solar activity
Fluctuations in Holocene atmospheric radiocarbon concentrations have been shown to be due to variations in solar activity. Analyses of both 10Be and 14 C nuclides con” rm that production-rate changes during the Holocene were largely modulated by solar activity. Analyses of peat samples from two intact European ombrotrophic bogs show that climatic deteriorations during the ‘Little Ice Age’ are associated with transitions to increasing atmospheric …
Mire-development pathways and palaeoclimatic records from a full Holocene peat archive at Walton Moss, Cumbria, England
Plant macrofossil data have been used to identify the successive mire communities occupying both central and marginal locations in the Walton Moss peatland complex, during the last 10 500 years. The reconstructed pathways of mire development indicate that early-Holocene fen and fen-carr communities were succeeded by species indicative of deep mire water tables and oligotrophic conditions. The character of the fen/bog transition (FBT) is compared …
Evidence for climatic deteriorations associated with the decline of Sphagnum imbricatum Hornsch. ex Russ. in six ombrotrophic mires from northern England and the Scottish Borders
The decline of Sphagnum imbricatum from the peat stratigraphy of six ombrotrophic mires (Bolton Fell Moss and Walton Moss, Raeburn Flow and Bell's Flow, and Coom Rigg Moss and Felecia Moss), has been investigated using colorimetric humification, quantitative plant macrofossil, and testate amoebae analyses. The chronology of each peat profile was determined by radiocarbon assay and pollen/land-use correlations. Palaeoclimate reconstructions have b…
Use of near-infrared reflectance spectroscopy (Nirs) in palaeoecological studies of peat
Bulk density, degree of humification,% moisture content and the% occurrence of plant macrofossils were determined down a single peat core. Near-infrared reflectance spectroscopy (NIRS) was used to obtain spectra for each sample and calibration equations were developed between the conventional analyses and the NIRS spectra using modified partial least squares and stepwise regressions. Conventional analyses were then correlated with values predicte…
