| 4 | Branched glycerol dialkyl glycerol tetraethers and paleoenvironmental reconstruction in Zoigê peat sediments during the last 150 years显示文摘Branched glycerol dialkyl glycerol tetraethers (GDGTs) were analyzed in peat samples taken from the Zoigê grassland, located on the eastern margin of the Qinghai-Tibetan Plateau. The mean annual air temperature (MAAT) and pH in the 210 Pb-dating peat core were reconstructed based on the cyclization of branched tetraethers (CBT) and methylation of branched tetraethers (MBT) indices for the last 150 years. The results showed that the MAAT and pH values involved three stages of variation over the last 150 years. The pH was stable and the MAAT decreased slowly by about 1°C from 1851 to 1927. The pH decreased rapidly by 0.6 and the MAAT decreased significantly by 2.5°C between 1927 and 1979. The pH and MAAT increased by 0.8 and 5°C, respectively, since the 1980s. The reconstructed temperatures correspond well to the mean winter temperatures reconstructed using tree-rings from the Jiuzhaigou Valley, situated at the boundary between the Qinghai-Tibetan Plateau and the Sichuan Basin. The estimated MAAT was similar to the temperatures reconstructed using tree-rings, indicating an increasing trend, as shown by local instrumental records from 1957 to 2001. These results provide further confidence in the application of proxies based on glycerol dialkyl glycerol tetraethers in peat records for continental paleoclimate reconstruction. | ZHOU HaoDa HU JianFang MING LiLi PENG PingAn ZHANG Gan | 2011 | Chinese Science Bulletin2011,56,23: | 9 |

| 14 | Distribution of branched glycerol dialkyl glycerol tetraethers in soils on the Northeastern Qinghai-Tibetan Plateau and possible production by nitrite-reducing bacteria显示文摘Branched glycerol dialkyl glycerol tetraethers(b GDGTs) are ubiquitous and abundant in soils, but their sources remain elusive. Recent studies demonstrate that the distributions of b GDGTs are sensitive to various environmental factors. In an effort to understand how and to what extent soil moisture(expressed as soil water content(SWC) or mean annual precipitation(MAP), p H and temperature may impact the distribution of b GDGTs, and to shed more light on the biological sources of b GDGTs in cold and arid regions, we investigated the distribution of b GDGTs as well as bacterial 16 S r RNA gene and functional genes involved in the N cycle(including amo A, nir S and nir K) in 41 surface soil samples from around Lake Qinghai and east of Qaidam Basin on the Northeastern Qinghai-Tibetan Plateau. We found that lower soil moisture reduced the fractional concentrations of cyclic b GDGTs and thus the cyclisation ratio of branched tetraethers(CBT) index correlated negatively with SWC and MAP, suggesting that soil moisture is an important factor controlling b GDGT distributions in soils in this arid and semi-arid region. Two subgroups of b GDGTs were assigned on the basis of cluster analysis, and b GDGT indices behaved differently in the two groups, hinting at different biosynthetic mechanisms for b GDGTs under different environmental conditions. Real time PCR results showed that nir S and nir K genes correlated significantly with the concentration of b GDGTs, suggesting that the nir S- or nir K-encoding bacteria involved in denitrification might potentially be an additional biological source for soil b GDGTs(besides Acidobacteria). Moreover, our results also support the application of new indices based on 5-methyl b GDGTs and 6-methyl b GDGTs in reconstructing past temperature and p H variations in this region. | SUN ChiJun ZHANG ChuanLun LI Fu Yan WANG HuanYe LIU WeiGuo | 2016 | Science China Earth Sciences2016,59,9: | 3 |

| 18 | Occurrence and distribution of hydroxylated isoprenoid glycerol dialkyl glycerol tetraethers(OH-GDGTs) in the Han River system, South Korea显示文摘We investigated the occurrence and distribution of terrestrial-derived hydroxylated isoprenoid glycerol dialkyl glycerol tetraethers(OH-GDGTs) in the Han River system and their potential impact on the application of the ring index of OH-GDGTs(RI-OH) as a sea surface temperature(SST) proxy in the eastern Yellow Sea. Thereby, we analyzed various samples collected along the Han River and from its surrounding areas(South Korea, n = 34). The OHGDGTs were found in all samples investigated. OH-GDGT-0 was the dominant OH-GDGT component in the estuary and marine samples while OH-GDGT-2 was generally dominant in the soils, the lake sediments and the river suspended particulate matter(SPM). Our results thus suggests a possible warm bias of the RI-OH-derived summer SSTs in the coastal zone to which a large amount of terrestrial organic matter is being supplied. Further studies are necessary to better assess the applicability of the RI-OH proxy in the eastern Yellow Sea. | Sujin Kang Kyoung-Hoon Shin Jung-Hyun Kim | 2017 | Acta Geochimica2017,36,3: | 3 |
