“…These small closed lakes are very sensitive to changes in regional climate and local ecosystem, and to anthropogenic influences in their catchment area. These remarkable lakes have been the subject of numerous studies focused on reconstructing paleoclimatic changes at high resolution and on varve formation [Mingram et al, 2004;Chu et al, 2005Chu et al, , 2009Schettler et al, 2006aSchettler et al, , 2006bParplies et al, 2008;Jiang et al, 2008;You et al, 2008]. A special type of lamination, dinocyst varve, was observed in the sediments of the Lake Xiaolongwan Liu et al, 2008].…”

[1] A multiproxy record from Lake Xiaolongwan, northeastern China, reveals distinct stratigraphical patterns in organic carbon, total nitrogen, organic carbon isotope, nitrogen isotope, clastic content and dinocyst concentration, over the past 1600 years. High atomic C/N ratios in the sediment suggest that a large amount of organic matter in the sediments is derived from vascular plants and soil in the catchment. Based on the good agreement between cyclical variations of d 13 C org in the sediments and the spring drought index from historical documents, we interpret that the variation of d 15 N values in the studied lake are most likely influenced by the duration and intensification of lake overturn, which regulates the amount of depleted d 15 N nutrients (dissolved organic nitrogen and ammonium) and dinoflagellate blooms.

Detailed information on the geography, recent climate and vegetation of this region and the characteristics of its volcanic lakes can be found in MingRaM et al (2004), stebiCh et al (2009 and Chu et al (2011). For ecological information, the pH, conductivity, and the concentrations for the main cations, anions and nutrients were measured on several occasions on water samples collected between 2005 and 2013.…”

Staurosira longwanensis sp. nov. is described from Sihailongwan maar lake, northeast China. The morphology of this new species is documented with light and scanning electron micrographs and discussed in comparison with several small species of Fragilariaceae. Staurosira longwanensis belongs in the genus Staurosira since it shares many features with taxa currently ascribed to it such as the position and characteristics of the spines, the characteristics of the areolae and apical pore fields. Apart from the type locality, S. longwanensis also occurs in another volcanic lake in northeast China, with circumneutral and oligotrophic water. Diatom analysis of the long sedimentary record retrieved from Lake Sihailongwan indicates that S. longwanensis has been present at low relative abundances in this lake at least since the Late Pleistocene.

Varve counts with AMS 14 C, 137Cs and 210 Pb dating of sediments (0-900 cm) from Erlongwan Maar Lake, NE China were used to establish a high-resolution chronology series for the late Quaternary. Dry density, total organic carbon (TOC) content, total nitrogen (TN) content, TOC/TN ratios and stable organic carbon isotope (  13 C org ) ratios were continuously analyzed on this sediment profile. On the basis of lithological characters, sporo-pollen assemblages and geochemical analyses, we identified 6 climate stages within the last 14 ka BP. The time before the Holocene (14-11.4 ka BP) represents a higher-order oscillation climatic transitional period (I). The entire Holocene climate development (from 11.4 ka BP to present) exhibited an increasing temperature trend, although there were cold and warm alternations (II-VI). The periods included were: II (11.4-9.05 ka BP) warm-wet stage, III (9.05-7.4 ka BP) cold and warm fluctuation stage, IV (7.4-4.2 ka BP) smoothly warming climate stage, V (4.2-1.67 ka BP) climate optimum stage, and VI (from 1.67 ka BP to present) cool and drier stage. Each climate stage began with a warming event and ended with an abrupt cooling event. This climate change cycle had unequal time spaces that were progressively shorter over time. Several abrupt climate shifts occurred at about 9. 4-9.05, 8.5-8.2, 7.8-7.4, 4.6-4.2, 3.7-3.25, 2-1.67 and 0.3-0.03 ka BP. Thus, it can be seen that the climate has been warming since 1920 AD, which indicates a new climate stage. Erlongwan, Maar Lake sediments, varve, climate variability Citation:You H T, Liu J Q.
