Wildfires are considered to have played an important role in the land plants crisis during the Permian–Triassic (P–T) transition. However, the nature and impact of wildfires in the P–T terrestrial crisis remains unclear. Organic petrology data from a terrestrial sequence from southwestern China show that the inertinite content ranges from 21.3% to 80.9% (mean 44.5%), suggesting that wildfires were

Modern pollen-plant diversity relationship in open landscapes of Tibetan Plateau Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-03-06 Mengna Liao, Yili Jin, Kai Li, Lina Liu, Nannan Wang, Jian Ni, Xianyong Cao
Past plant diversity dynamics can provide a historical perspective on biodiversity change and ecosystem dynamics as a guide to conservation management in the future. Pollen analysis is one of the most widely used approaches to reconstruct plant diversity change through time, but the representativeness of pollen diversity to plant diversity is not yet fully understood and especially in open landscapes

An abrupt vegetation change on south-central Yunnan Plateau (Southwest China) during the last deglaciation Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-03-06 Mengna Liao, Kai Li, Jian Ni, Yun Zhang, Yumei Li
The magnitude and pace of anthropogenic climate change are increasing the likelihood of abrupt changes in terrestrial ecosystems worldwide. The Last Deglacial Transition (LDT) witnessed global and regional climate change and caused vegetation change globally. The recognition and attribution of deglacial abrupt vegetation conversion would certainly enhance our understanding on the survivability and

Re-investigation of fossil Lemmini specimens from the early and Middle Pleistocene of Western and Central Europe: Evolutionary and paleoenvironmental implications Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-03-06 Arbez Louis, Hadravová Tereza, Royer Aurélien, Montuire Sophie, Fejfar Oldřich, Horáček Ivan
The current study focuses on the emblematic / species complex (tribe Lemmini) in the European Pleistocene fossil record. The members of the two genera occupy distinct ecological niches and have different external appearances, but they are remarkably similar in their dental morphology, so that they were commonly thought of as undistinguishable in the fossil record. Thus, more or less all European Lemmini

The variability of Intermediate water intrusion into the South China Sea during the last deglaciation Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-03-04 Yiping Yang, Rong Xiang, Fuchang Zhong, Sui Wan
Millennial-scale variations of the intermediate water in the South China Sea (SCS) have not been well understood due to limited data. Here we investigate the temperature and δO of seawater (δO, a proxy of salinity) evolution history of the intermediate water during the last deglaciation by analyzing Mg/Ca and oxygen isotopes of planktonic foraminifera in the southern SCS. The results indicate that

Paleoecology and paleobiogeography of the latest Miocene site of Shuitangba, Zhaotong, China Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-02-28 D.F. Su, J. Kelley, L.J. Flynn, X.P. Ji, C.L. Deng, T. Deng, P. Li, Z. Li, W.J. Sanders, T.A. Stidham, F. Sun, X. Wang, Y. Wang, D. Youlatos, N.G. Jablonski
Apart from northern and central China, the fossil record of the latest Miocene and Early Pliocene of Asia is not well documented and the record of South China during this interval is especially poor. Shuitangba, a site in Yunnan Province, offers a rare window into the paleoenvironment of the latest Miocene in southwestern China. Over 2400 vertebrate and macrobotanical specimens have been recovered

A quantitative method to infer lake area changes based on an extensive survey of lake surface sediment grain size across the Inner Mongolia Plateau, and its application to understanding the evolution of Lake Wulanhushao in northern China since 18.59 cal. kyr BP Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-02-27 Zhennan Liu, Wei Wang, Zhimei Niu, Yajuan Jiang, Xue Wen, Zhuoran Lv, Hanyang Wang, Jiang He, Changwei Lv, Yuzhen Ma
Grain size is commonly used as a proxy to reconstruct past lake hydrology; however, published research rarely links grain size with modern processes, and uncertainties exist for interpretation. In this paper, we decompose the grain size frequency distributions (GSFD) for 196 lake surface sediments from 61 lakes and 9 reservoirs across the Inner Mongolia Plateau and adjacent areas and divide them into

Geographical distributions and ecological ranges of the dominant snail species in China and their palaeoclimatic implications Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-02-27 Yajie Dong, Naiqin Wu, Fengjiang Li, Houyuan Lu
Fossil land snails in aeolian sediments are useful for reconstructing past environments, but quantitative knowledge about their geographical and climatic distribution is limited. We conducted a systematic survey of snails in 402 surface soil samples from China, spanning the climatic range from cold temperate to subtropical. The dominant snail species include , , , , , , and . Using the Maximum Entropy

Forest or grassland? Late Pliocene vegetation and climate of the Yushe Basin, Northern China Palaeogeogr. Palaeoclimatol. Palaeoecol. (IF 3.0) Pub Date : 2024-02-27 Hanlin Wang, Yao Wang, Lin Zhao, Huayu Lu
The Pliocene warm period is regarded as an analogue of future warming, and quantitative reconstruction of palaeovegetation and palaeoclimate during this period is helpful for predicting vegetation and climate changes in the future. Here, we quantitatively reconstructed the late Pliocene vegetation and climate based on phytolith assemblages from the Upper Zhangcun Formation in the Yushe Basin, Northern
