The Acadian Forest is a mixed-wood forest covering the Canadian provinces of New Brunswick and Nova Scotia. Picea rubens (red spruce) is its signature species which has been prominent for circa 2000 years. We extracted a 124 cm surface core...

Black carbon is a paleofire proxy that has been measured from glacial ice, snow, soils and lake sediments, though relatively few comparisons have been made with other fire indicators in sedimentary geoarchives. Microscopic charcoal, quantif...
An archaeobotanical and stable isotope approach to changing agricultural practices in the NW Mediterranean region around 4000 BC [0.03%]
考古植物学和稳定同位素在公元前4000年左右西北地中海地区农业实践变化中的应用研究

Ferran Antolín et al.
It has recently been observed, that a change in the crop spectrum happened during the so-called Middle Neolithic in France at ca. 4000 BC. An agricultural system based on free-threshing cereals (naked wheat and naked barley) seems to shift ...
Species-specific reservoir effect estimates: A case study of archaeological marine samples from the Bering Strait [0.03%]
来自白令海峡考古海洋样本的物种特异性库效应估计：以案例研究为例

Jack Pr Dury et al.
Due to the marine reservoir effect, radiocarbon dates of marine samples require a correction. Marine reservoir effects, however, may vary among different marine species within a given body of water. Factors such as diet, feeding depth and m...
Observations on the connection between glacial phases, natural catastrophes and economic trends of the last millennium in Italy [0.03%]

Humanity has often faced critical phases determined by climate changes combined with other natural catastrophes that implied significant socio-economic consequences. In this article, we present an observational study on the possible systema...
Growth rates for freshwater ferromanganese concretions indicate regional climate change in eastern Canada at the Northgrippian-Meghalayan boundary [0.03%]
加拿大东部北格里皮安-梅格哈尔亚ン界线附近淡水富铁锰结核增长速率表明区域气候变化
Simon Hayles,Tom Al,Jack Cornett et al.
Simon Hayles et al.
The existence of freshwater ferromanganese concretions has been known for decades, but we are not aware of a generally accepted explanation for their formation, and there has been little research into their potential use as records of Holoc...
Monumental landscapes of the Holocene humid period in Northern Arabia: The mustatil phenomenon [0.03%]
阿拉伯北部全新世湿润期的纪念碑景观：mustatil现象

Between 10 and six thousand years ago the Arabian Peninsula saw the most recent of the 'Green Arabia' periods, when increased rainfall transformed this generally arid region. The transition to the Neolithic in Arabia occurred during this pe...
Are there enormous age-trends in stable carbon isotope ratios of oak tree rings? [0.03%]
橡树年轮中稳定的碳同位素比值有巨大的年龄变化趋势吗？
Danny McCarroll,Josie E Duffy,Neil J Loader et al.
Danny McCarroll et al.
We test a recent prediction that stable carbon isotope ratios from UK oaks will display age-trends of more than 4‰ per century by measuring >5400 carbon isotope ratios from the late-wood alpha-cellulose of individual rings from 18 modern o...
Genetic evidence for a western Chinese origin of broomcorn millet (Panicum miliaceum) [0.03%]
遗传证据表明中国西部是粟的起源中心

Harriet V Hunt et al.
Broomcorn millet (Panicum miliaceum) is a key domesticated cereal that has been associated with the north China centre of agricultural origins. Early archaeobotanical evidence for this crop has generated two major debates. First, its contes...
Columbus' environmental impact in the New World: Land use change in the Yaque River valley, Dominican Republic [0.03%]

Henry Hooghiemstra,Thomas Olijhoek,Menno Hoogland et al.
Henry Hooghiemstra et al.
Columbus' arrival in the New World in AD 1492 on the northern coast of Hispaniola was followed by a suite of changes in land-use. We reconstruct environmental change from a 225-cm-long sediment core from site Los Indios from an abandoned an...
