“…The East Asian monsoon system, which has directly influenced the Xingkai Basin, was established in the early Miocene (Guo et al, 2008). Most of the plant taxa in the region are temperature sensitive and therefore would be strongly affected by the intensity of EAWM, which is an important determinant of whether temperate plants can survive the winter (Bondarenko et al, 2017; Lyu et al, 2018).…”

“…In addition, the latitude of the Xingkai Basin corresponds roughly to their northern distribution limit in the Holocene (Fang et al, 2011). Despite the large climatic fluctuations since the Pliocene, these thermophilous trees underwent limited evolutionary changes in terms of their climatic tolerance (Svenning, 2003; Bondarenko et al, 2017); their response to warm and cold climatic shifts was to migrate northward and southward, respectively. Therefore, we assume that variations in the percentages of the pollen of the thermophilous trees in core XK12 can be used as a sensitive indicator of fluctuations in EAWM intensity since the Pliocene.…”

A 328.58 m drill core (XK12) was recovered from lacustrine–alluvial sediments in the Xingkai Basin, northeast China, with the aim of obtaining a high-resolution pollen record of East Asian winter monsoon (EAWM) evolution since 3.6 Ma. An index based on the pollen record of thermophilous trees and terrestrial herbs is used as an indicator of winter temperature conditions controlled by the EAWM, at the glacial–interglacial scale. Primary age control was established based on lithostratigraphy and magnetostratigraphy, and then the pollen index was correlated to the LR04 global benthic δ18O record and finally tuned to Earth orbital obliquity to produce a high-resolution astronomical time scale. The pollen record indicates that the EAWM underwent two stepwise enhancements at 2.8 and 1.6 Ma. These events are consistent with paleoclimatic records of mean quartz grain size from the Chinese Loess Plateau, and they are also in accord with the initiation and intensification of Northern Hemisphere glaciation. Our findings suggest that the variability of the EAWM since 3.6 Ma was primarily controlled by changes in global ice volume and climatic cooling.

“…This could probably be due to the fact that the PFT 25 and 26 were excluded during the likelihood procedure. According to Bondarenko, Blokhina, Bruch, Henrot, and Utescher (2017), IPR vegetation analysis also shows a warmer aspect of the vegetation in the Early Pleistocene when compared to the PFT approach. This effect can be explained by the fact that in the IPR, potentially azonal elements, including mainly broadleaved deciduous taxa, are a priori excluded when identifying the biome type.…”

Paleogene vegetation changes in Primorye (Far East of Russia) are studied using the Plant Functional Types (PFT) Approach, for the first time applied on the large palaeobotanical records of this region. The palaeobotanical data for this reconstruction are based on the analysis of 30 palynofloras and 24 leaf floras covering the Early Palaeocene to Late Oligocene. The vegetation reconstruction at the level of PFTs in general points to the presence of mesophytic forest vegetation in Primorye throughout the Paleogene. While in the Palaeocene vegetation of Primorye was of temperate deciduous type, warm temperate‐mixed evergreen‐deciduous forests dominated in the Eocene and Early Oligocene. In the Late Oligocene, the vegetation of Primorye was again primarily deciduous, mixed evergreen‐deciduous forests persisted at places. The observed vegetation patterns and their changes through time in many cases can be correlated with spatial climate patterns and the overall continental palaeoclimate evolution, as recently reconstructed from the same palaeobotanical record. The higher‐than‐present spatial homogeneity of Paleogene vegetation coincides with shallow temperature gradients and a significantly more humid regional rainfall pattern over Primorye during the Paleogene.

“…According to Kovar-Eder et al (2008) and Teodoridis et al (2011), with zonal herb proportions ranging from 0 to 22 %, except the late Eocene LF 18 constituting 37.5 % of herbs, no open woodland is reconstructed for the Primorye Re gion throughout the Paleogene based on the IPR-vegeta tion analysis. Moreover, according to Bondarenko et al (2017), in the early Pleistocene the zonal herb proportion was ranging from 18 to 37 %. Thus, a close forest cover likely existed in Primorye throughout most of the Cenozoic.…”
