“…The latter period is consistent with the proposed Little Ice Age identified in AM-23. It has been suggested, from low pollen and also charcoal concentrations in a highresolution pollen record from a Maar lake Erlongwan in northeast China, that there were coldest winters with high snowfall, relative drier summers and less intensive wildfire between 1500 and 1850 AD, coincident also with the Little Ice Age (Li et al, 2013). On Rishiri Island of Japan, a pollen record revealed that modern Picea glehnii forest might have been formed during the Little Ice Age (Igarashi, 2013).…”

a b s t r a c tThe Amur Basin, on the border of Russia and China, has accumulated substantial quantities of peat that have allowed the reconstruction of past vegetation and environments, especially during the Holocene. In this paper, a detailed pollen record from the Basin has been constructed for the last 3800 years and interpreted with the assistance of 40 surface pollen samples taken from vegetation types representative of a broader region. In addition, fossil microcharcoal counts were undertaken to explore variation in fire frequency and the role of fire in peat development and landscape disturbance. The record can be divided into four periods. (1) A period of deciduous broadleaved forest dominated by Betula and Quercus accompanied by thriving sedge-dominated wetlands indicating relatively warm and wet conditions between about 3800 and 2000 cal BP. (2) Coniferous and broad-leaved mixed forest domination between about 2000 and 680 cal BP indicating a shift to a cooler climate. (3) Betula-dominant deciduous forest, reduced sedge-dominated wetlands and increased burning between about 680 and 250 cal BP indicating further drying and cooling during the Little Ice Age. (4) Secondary pine forest combined with a large increase in fire activity as well as a further reduction in the swamp environment signaling substantial human impact in the last 250 years.

“…China has only started relatively late in this field. Most studies on fire history are concentrated in northern China (Li et al, 2005;Huang et al, 2006;Jiang et al, 2008;Han et al, 2012;Li et al, 2013;Wang et al, 2013;Z. Q.

Postglacial fire history and interactions with vegetation and climate in southwestern Yunnan Province of China

Abstract.A high-resolution, continuous 18.5 kyr (1 kyr = 1000 cal yr BP) macroscopic charcoal record from Qinghai Lake in southwestern Yunnan Province, China, reveals postglacial fire frequency and variability history. The results show that three periods with high-frequency and high-severity fires occurred during the periods 18.5-15.0, 13.0-11.5, and 4.3-0.8 ka, respectively. This record was compared with major pollen taxa and pollen diversity indices from the same core, and tentatively related to the regional climate proxy records with the aim to separate climate-from human-induced fire activity, and discuss vegetation-fire-climate interactions. The results suggest that fire was mainly controlled by climate before 4.3 ka and by the combined actions of climate and humans after 4.3 ka. Before 4.3 ka, high fire activity corresponded to cold and dry climatic conditions, while warm and humid climatic conditions brought infrequent and weak fires. Fire was an important disturbance factor and played an important role in forest dynamics around the study area. Vegetation responses to fire after 4.3 ka are not consistent with those before 4.3 ka, suggesting that human influence on vegetation and fire regimes may have become more prevalent after 4.3 ka. The comparisons between fire activity and vegetation reveal that evergreen oaks are flammable plants and fire-tolerant taxa. Alnus is a fire-adapted taxon and a nonflammable plant, but density of Alnus forest is a key factor to decide its fire resistance. The forests dominated by Lithocarpus/Castanopsis and/or tropical trees and shrubs are not easy to ignite, but Lithocarpus/Castanopsis and tropical trees and shrubs are fire-sensitive taxa. Fire appears to be unfavourable to plant diversity in the study area.

“…Promising for studies are small shallow lakes, where a high velocity of sedimentation permits palaeoclimatic parameters to be recorded with annual to decadal resolution. A minimum of post-sedimentation changes in bottom sediments ensures accuracy of the acquired knowledge on past environmental and climate conditions at regional and global scale (Last and Smol, 2001;Peck et al, 2002;Subetto, 2009;Swann et al, 2010;Hernandez et al, 2013;Leng et al, 2013;Li et al, 2013). In the past decade researchers have paid special attention to investigating past climate changes and factors leading to switches between glacial and interglacial conditions.…”

a b s t r a c tThe last glacial maximum and late glacial environmental and climatic variability in the Baikal region, southern Siberia, Russia has been studied in a sediment sequence from Lake Kotokel, located 2 km east of Lake Baikal, using the oxygen isotope composition of diatom silica (d 18 O diatom ). The purification of diatom frustules involved the process of trimethylsilylation, which has been shown to be suitable for preparation of diatoms for oxygen isotope analysis. The Lake Kotokel d 18O diatom record presented here spans intervals from about 24.6 to 22.9 ka BP (further referred to as 'last glacial maximum') and~16.7e11.5 ka BP (further referred to as 'late glacial') displaying variations in the oxygen isotope composition between þ26.7 and þ31.2‰. Overall high d18 O diatom values of about þ29 to þ31‰ during the two investigated intervals characterize a strongly evaporative lake system in a dry environment and suggest a lower than present lake level due to enhanced evaporation. The Lake Kotokel diatom isotope record is roughly in line with the 60 N summer solar insolation, pointing to a linkage to broader-scale climate change, but displays weaker reaction to short-term climatic oscillations, i.e. Bølling-Allerød or Younger Dryas. The climate warming at~14.3 ka BP is marked by negative spikes in the d18 O diatom record due to isotopically low melt water input from the mountainous hinterland.
