Drivers of land cover and plant compositional changes in Northeast China since the mid-Holocene
A humification-based method toward refining Holocene radiocarbon chronologies
Holocene paleoclimate reconstructions and comparisons largely rely on accurate age-depth modeling. However, uncertainties in chronology, such as those caused by sparse radiocarbon dates, will hamper inter-core comparisons and correlations, and might result in misleading “cause and consequence” conclusions. This study aimed to find a solution to increase the comparability and minimize the uncertainty of wetland chronology as much as possible. Sedi…
Agricultural systems regulate plant and insect diversity and induce ecosystem novelty
Land-use change plays an important role in shaping plant and insect diversity over long time timescales. Great Britain provides an ideal case study to investigate patterns of long-term vegetation and insect diversity change owing to the existence of spatially and temporally extensive environmental archives (lake sediments, peatlands, and archaeological sites) and a long history of landscape transformation through agrarian change. The trends ident…
Evidence for the Little Ice Age in upland northwestern Europe
The Little Ice Age (LIA) is a well-recognised palaeoclimatic phenomenon, although its causes, duration and severity have been matters of debate and dispute. Data from a wide range of archives have been used to infer climate variability before, during and after the LIA. Some published proxy-climate data from peatlands imply that two particularly severe episodes within the LIA may be contemporaneous between hemispheres; these echo a previous climat…
Linking Holocene East Asian monsoon variability to solar forcing and Enso activity
High-resolution proxy-based paleoenvironmental records derived from peatlands provide important insights into climate changes over centennial to millennial timescales. In this study, we present a composite climatic index (CCI) for the Hani peatland from northeastern China, based on an innovative combination of pollen-spore, phytolith, and grain size data. We use the CCI to reconstruct variations of the East Asian summer monsoon (EASM) intensity d…
Landscapes of sweet chestnut ( Castanea sativa ) in Britain — their ancient origins
Sweet chestnut Castanea sativa has been regarded as a Roman archaeophyte in Britain ever since a debate in the eighteenth century contested whether it was indigenous or introduced. This paper re-examines its status, presenting new evidence within an ‘historical ecology’ analytical framework. Sweet chestnut trees and coppice stools from 237 sites across England and Wales were assessed using genetic, dendrochronological, palaeoenvironmental, archae…
An 8000-year multi-proxy peat-based palaeoclimate record from Newfoundland
Energy carried by warm tropical water, transported via the Atlantic Meridional Overturning Circulation (AMOC), plays a vital role in regulating the climate of regions bordering the North Atlantic Ocean. Previous phases of elevated freshwater input to areas of North Atlantic Deep Water (NADW) production in the early to mid-Holocene have been linked with slow-downs in the AMOC and changes in regional climate. Newfoundland’s proximity in the North A…
Records of East Asian monsoon activities in Northeastern China since 15.6 ka, based on grain size analysis of peaty sediments in the Changbai Mountains
The ‘Little Ice Age’
Social-ecological systems in the Anthropocene
Understanding social-ecological system dynamics is a major research priority for sustainable management of landscapes, ecosystems and resources. But the lack of multi-decadal records represents an important gap in information that hinders the development of the research agenda. Without improved information on the long-term and complex interactions between causal factors and responses, it will be difficult to answer key questions about trends, rat…
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…
Dating Recent Peat Accumulation in European Ombrotrophic Bogs
This study compares age estimates of recent peat deposits in 10 European ombrotrophic (precipitation-fed) bogs produced using the 14 C bomb peak, 210 Pb, 137 Cs, spheroidal carbonaceous particles (SCPs), and pollen. At 3 sites, the results of the different dating methods agree well. In 5 cores, there is a clear discrepancy between the 14 C bomb peak and 210 Pb age estimates. In the upper layers of the profiles, the age estimates of 14 C and 210 P…

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…
Linking past cultural developments to palaeoenvironmental changes in Estonia
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…
An Ecological Context for the Post-Roman Archaeology of the Somerset Moors (South West England, UK)
In contrast to the widely reported research into the wetland prehistory of the Somerset Moors and Levels, the wetland archaeology for the historic periods of this region of south west England has always been less well known, being reliant on mostly non-wetland sources of information, e.g. documentary evidence, cartographic studies and inferences made from dry land archaeological sites. This study attempts to correct this imbalance by outlining pa…
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 …
Mineral deficiency and the presence of Pinus sylvestris on mires during the mid- to late Holocene
Pollen records across parts of Ireland, England and northern Scotland show a dramatic collapse in Pinus pollen percentages at approximately 4000 radiocarbon years BP. This phenomenon has attracted much palaeoecological interest and several hypotheses have been put forward to account for this often synchronous and rapid reduction in pine from mid-Holocene woodland. Explanations for the ‘pine decline’ include prehistoric human activity, climatic ch…
Holocene environmental change
Peatlands provide a widespread terrestrial archive of Holocene environmental change. The taphon omy of peat is relatively simple, the range of evidence and proxies is wide, and dating methods have become more accurate and precise, such that the potential temporal resolution of records is high. Although long estab lished, the use of peatlands as archives of Holocene change has undergone phases of decline and resurgence. Here, the variable exploita…
A sensitive high-resolution record of late Holocene climatic change from a raised bog in northern England
Proxy-climatic data in the form of plant macrofossils have been analysed from a 5 m core from Bolton Fell Moss, Cumbria, UK. Detailed analysis of peat from the upper 50 cm of this core is used to demonstrate a strong correlation between changes in the relative proportion of taxa and known climatic changes over the last 1000 years. The record of changes in bog vegetation contained within the peat profile is used to reconstruct changes in bog-surfa…
A 5500-year proxy-climate and vegetation record from blanket mire at Talla Moss, Borders, Scotland
A monolith of peat taken from an upland blanket mire at Talla Moss, southern Scotland, was sub jected to peat humification and pollen analyses to produce both a proxy-climate record and a vegetational history covering the last 5500 years. While the peat showed little visible stratigraphy, with no intimation of major peat humification changes, colorimetric data indicate a markedly oscillatory climate record, which is apparently largely independent…

Proxy records of climate from blanket mires
Pioneer studies of peat stratigraphy in Scandinavia led to division of the Holocene into climatic periods, and though this scheme was later re-evaluated and partly rejected, studies in Denmark and England have demonstrated a link between the stratigraphy of lowland raised mires and past climatic change. Recent work has indicated the potential also for proxy climatic records from upland blanket mires. In a new study, radiocarbon dating of changes …

Tephrostratigraphy of An Loch Mór, Inis Oírr, western Ireland
Twelve definable cryptotephra layers younger than c. 8600cal. BP are reported from lacustrine core material taken from An Loch Mór, Inis Oírr, Aran Islands, western Ireland. The geochemistry of these shard layers, which represent more Holocene tephras than previously geochemically characterized from any European site outside the proximal volcanic influence of Italy or Iceland, is presented. Of these tephras, four may correlate with known Iceland-…

The environmental impact of prehistoric mining at Copa Hill, Cwmystwyth, Wales
A recent upsurge of interest in early mining and metal working sites in Europe led to experimental quantification of their apparently prodigious demand for fuelwood. However, the real impact of prehistoric mining on woodland remained unknown. Excavation of a prehistoric copper mine at Copa Hill, Cwmystwyth, from 1986-91, afforded an opportunity for linked palaeoenvironmental investigations. Pollen analytical methods were applied in a pilot study …
Paradigm shifts in late-Holocene climatology
The climatic consequences of major increases in the concentration of atmospheric carbon dioxide were calculated over 100 years ago, but only during the last two decades have the effects of human-induced increases in various atmospheric gas concentrations become a concern of a wide range of scientists. The near-century delay between the propounding of the theory and the widespread recognition of the consequences for climate of continuing human act…

The Environmental Setting of Erw-wen and Moel y Gerddi
The environmental setting of two late-prehistoric enclosures in upland Ardudwy, Gwynedd was investigated by pollen analysis of nearby valley mire deposits and of old ground surfaces revealed during excavation of the sites. Radiocarbon-dated pollen data indicate human influence on the local environment since Mesolithic times, with the major period of woodland clearance in the early Bronze Age. The two enclosures appear to have been constructed in …
The Palaeoecological Setting of Cefn Gwernffrwd — a Prehistoric Complex in Mid-Wales
Results of investigations into the palaeoecological setting of the stone-circle/ring-cairn prehistoric complex on Cefn Gwernffrwd, Mid-Wales are presented in two radiocarbon-dated pollen diagrams. Mesolithic and Neolithic environments of the locality are briefly discussed. The conjectured archaeological age of the complex is then considered and compared with the palaeoecological evidence. The latter indicates construction of the complex in two se…

Early Ironworking and its Impact on the Environment
The environmental impact of the Late Iron Age and Romano-British ironworking hillfort of Bryn y Castell in upland southern Snowdonia was investigated by multiple profile pollen and charcoal analysis of nearby valley mire and blanket peat deposits. Pollen data, collected from five radiocarbon dated profiles within a 1.5 km radius of the hillfort, indicate that ironworking activities apparently had only localised impact on the environment. Small-sc…

Climate Change and Human Impact on the Landscape
Excavation of a Bronze Age Unenclosed Cemetery, Cairns, and Field Boundaries at Eaglestone Flat, Curbar, Derbyshire, 1984, 1989–1990
Excavations at Eaglestone Flat, on the gritstone eastern uplands of the Peak District, have revealed a Bronze Age cremation cemetery associated with a number of contemporaneous stone structures built for ritual and agricultural purposes. Some of the burials were within urns, mostly cordoned. Others were simply placed in pits whilst still hot. A minority were deposited in direct association with small cairns, either placed under or within them. Th…

Climatic significance of the marginalization of Scots pine (Pinus sylvestris L.)c. 2500 BC at White Moss, south Cheshire, UK
Subfossil wood from White Moss, south Cheshire, has become the focus of palaeoenvironmental research employing not only conventional coring, pollen analysis, radiocarbon dating and dendrochronology on pine and oak, but also the exhumation of in situ peat areas and dendroecology of the pine ring-width records. Initial dendrochronological research at the site yielded five pine chronologies dating from 3520 to 2462 cal. bc. These and other data indi…
