Open AccessResponse of testate amoeba assemblages to peatland drain blocking
Peatlands represent globally important habitats and carbon stores. However, human impacts and climate change leave peatlands with a substantial management challenge. Degradation of peatland habitats and their ...

Open AccessRecent climate change has driven divergent hydrological shifts in high-latitude peatlands
High-latitude peatlands are changing rapidly in response to climate change, including permafrost thaw. Here, we reconstruct hydrological conditions since the seventeenth century using testate amoeba data from ...

Imminent loss of climate space for permafrost peatlands in Europe and Western Siberia
Human-induced climate warming by 2100 is expected to thaw large expanses of northern permafrost peatlands. However, the spatio-temporal dynamics of permafrost peatland thaw remain uncertain due to complex perm...

A ~ 40-year paleoenvironmental record from the Swan Oxbow, Yangtze River, China, inferred from testate amoebae and sedimentary pigments
We present a ~ 40–year record of environmental change in the Swan Oxbow, Yangtze River, China, inferred from testate amoeba and sedimentary pigment data, combined with remote sensing and analysis of local soci...

Open AccessMisinterpreting carbon accumulation rates in records from near-surface peat
Peatlands are globally important stores of carbon (C) that contain a record of how their rates of C accumulation have changed over time. Recently, near-surface peat has been used to assess the effect of curren...

Widespread drying of European peatlands in recent centuries
Climate warming and human impacts are thought to be causing peatlands to dry, potentially converting them from sinks to sources of carbon. However, it is unclear whether the hydrological status of peatlands ha...

Latitudinal limits to the predicted increase of the peatland carbon sink with warming
The carbon sink potential of peatlands depends on the balance of carbon uptake by plants and microbial decomposition. The rates of both these processes will increase with warming but it remains unclear which w...

Open AccessCorrection: Corrigendum: Solar cycles or random processes? Evaluating solar variability in Holocene climate records
Scientific Reports 6: Article number: 23961 published online: 05 April 2016; updated: 27 June 2016. A coding error in the Monte Carlo procedure for the determination of critical values in running correlation a...

Open AccessSolar cycles or random processes? Evaluating solar variability in Holocene climate records
Many studies have reported evidence for solar-forcing of Holocene climate change across a range of archives. These studies have compared proxy-climate data with records of solar variability (e.g. 14C or 10Be), or...

Open AccessThe long-term fate of permafrost peatlands under rapid climate warming
Permafrost peatlands contain globally important amounts of soil organic carbon, owing to cold conditions which suppress anaerobic decomposition. However, climate warming and permafrost thaw threaten the stabil...

Influence of ocean–atmospheric oscillations on lake ice phenology in eastern North America
Our results reveal long-term trends in ice out dates (1836–2013) for twelve lakes in Maine, New Brunswick and New Hampshire, in eastern North America. The trends are remarkably coherent between lakes (rs = 0.462–...

Open AccessFirst discovery of Holocene cryptotephra in Amazonia
The use of volcanic ash layers for dating and correlation (tephrochronology) is widely applied in the study of past environmental changes. We describe the first cryptotephra (non-visible volcanic ash horizon) ...

Open AccessSpheroidal carbonaceous particles are a defining stratigraphic marker for the Anthropocene
There has been recent debate over stratigraphic markers used to demarcate the Anthropocene from the Holocene Epoch. However, many of the proposed markers are found only in limited areas of the world or do not ...

Ecology of Testate Amoebae in an Amazonian Peatland and Development of a Transfer Function for Palaeohydrological Reconstruction
Tropical peatlands represent globally important carbon sinks with a unique biodiversity and are currently threatened by climate change and human activities. It is now imperative that proxy methods are develope...

Middle to late Holocene chironomid-inferred July temperatures for the central Northwest Territories, Canada
We analyzed subfossil chironomids, sediment organic matter and sediment particle size data from a 1.11-m-long freeze core collected from Carleton Lake (unofficial name), located approximately 120 km north of the ...

Controls on the contemporary distribution of lake thecamoebians (testate amoebae) within the Greater Toronto Area and their potential as water quality indicators
Thecamoebians were examined from 71 surface sediment samples collected from 21 lakes and ponds in the Greater Toronto Area to (1) elucidate the controls on faunal distribution in modern lake environments; and ...
