“…2 Ma. The time frame largely corresponded to the period of the profound climatic change in Asia interior, i.e., extremely intensive aridification in Middle to Central Asia demonstrated by paleoenvironmental data on loess and clay deposits ( An et al, 2001 ; Ma et al, 2005 ; Nie et al, 2014 ; Wang X. et al, 2016 ), which may be due to the synergy of recently geological activity of Northern QTP ( Miao et al, 2012 ; Favre et al, 2015 ; Shi et al, 2019 ; Yang et al, 2019 ). Our DIVA analysis also indicated the origin of Chrysanthemum -group in Central Asia, followed by an eastward dispersal of the Chrysanthemum lineage, and in situ diversification or colonization of the Ajania lineage along with tectonic activities of QTP ( Table 3 and Supplementary Figure 2 ; Chen et al, 2020 ).…”

“…In East Asia, the process of species diversification has been greatly influenced by the topographic activities of the Northern Qinghai-Tibet Plateau (QTP) and the aridification in Asian interior ( Zheng et al, 2000 ; An et al, 2001 ; Guo et al, 2004 ; Miao et al, 2012 ; Ge et al, 2013 ; Li et al, 2015 ; Shi et al, 2015 ; Spicer, 2017 ; Shi et al, 2019 ; Ding et al, 2020 ). To what extent have ecogeographical gradients and diverse macrohabitats in this region promoted speciation ( He et al, 2010 ; Qin et al, 2013 ; Yan et al, 2013 )?…”

Understanding the roles played by geography and ecology in driving species diversification and in the maintenance of species cohesion is the central objective of evolutionary and ecological studies. The multi-phased orogenesis of Qinghai-Tibetan Plateau (QTP) and global climate changes over late-Miocene has profoundly influenced the environments and evolution of organisms in this region and the vast areas of Asia. In this study, we investigate the lineage diversification of Chrysanthemum-group in subtribe Artemisiinae (tribe Anthemideae, Asteraceae) likely under the effects of climate changes during this period. Using DNA sequences of seven low-copy nuclear loci and nrITS and the coalescent analytical methods, a time-calibrated phylogeny of subtribe Artemisiinae was reconstructed with emphasis on Chrysanthemum-group. The monophyletic Chrysanthemum-group was well resolved into two major clades corresponding to Chrysanthemum and Ajania, two genera which can be well identified by capitulum morphology but have been intermingled in previous plastid and ITS trees. Within Chrysanthemum, a later divergence between Ch. indicum-complex and Ch. zawadskii-complex can be recognized. The time frames of these sequential divergences coincide with the late Cenozoic uplift of the Northern QTP and the concomitant climatic heterogeneity between eastern and inland Asia. Reconstruction of historical biogeography suggested the origin of Chrysanthemum-group in Central Asia, followed by eastward migration of Chrysanthemum and in situ diversification of Ajania. Within Chrysanthemum, Ch. indicum-complex and Ch. zawadskii-complex exhibited contemporary distributional division, the former in more southern and the latter in more northern regions. The geographic structure of the three lineages in Chrysanthemum-group have been associated with the niche differentiation, and environmental heterogenization in Asia interior.

“…Although most previous studies have focused on the (both thermal and mechanical) climate impact of the large and high Tibet Plateau (An et al., 2001; Molnar et al., 2010; Wu et al., 2014), several studies also revealed the important roles of other mountains, for example, Tian Shan (Baldwin & Vecchi, 2016), Yunnan–Guizhou and Mongolian Plateau (Sha et al., 2015; Shi et al., 2019), mountains in India and Indochina (Wang et al., 2006), and Zagros Mountains (Tang et al., 2012), in shaping Asian climate. In agreement with these studies, our simulations further demonstrate that the Southeast Mountains were also critical in shaping the East Asian climate during the Eocene.…”

Several regional climates during the Eocene are still under debate, and the Eocene environment of China is a particular focus of the discussion. One view, based on the widely distributed pollen of Ephedripites, as well as red beds and evaporite sediments, suggests that a dry zonal belt (Figure 1a) dominated mid-latitude China from west to east (Guo et al., 2002,;Sun & Wang, 2005;Wang, 1990). To the north and the south of the arid zonal belt, humid climates appeared in Northeast and South China, where pollen assemblages indicative of humid conditions, as well as coal and oil shales, occur in Eocene sediments (

“…The mining area is derived from lower Cambrian siliceous dolomite strata that contain phosphorite with a P 2 O 5 proportion as high as 36% (Xiao et al, 2019). The mean altitude of the Yunnan Plateau is approximately 2,000 m, and the climate is relatively dry and warm with a mean annual precipitation of 994 mm and a mean annual temperature of 15.1°C due to the foehn effect of the surrounding mountains (Shi et al, 2019). The profiles were covered by natural woodlands and grasslands and sampled on both sides of a valley underlain by ore belts with various P contents deposited in a shallow marine environment (Z. R.

Magnetic particles associated with iron (Fe) oxides are widespread on the surface of Earth and Mars and serve as reasonable climatic indicators. Ferrimagnetic maghemite (Mgh) and antiferromagnetic hematite (Hm), which dominate magnetism and redness, often coexist or compete with each other in soils and sediments. The formation efficiency of Mgh relative to Hm could be modulated by geochemical background besides climate, especially by phosphate (P), which has a high affinity for the surfaces of precursor iron oxides in natural systems. We investigated two Ferralsol sequences around a P mining field with similar climates and contrasting P/Fe ratios. High P/Fe ratios retard iron oxide crystallization, grain growth, and transformation into Hm, thereby promoting more effective accumulation of ferrimagnetic Mgh as an intermediate product. The lack of ligand-protected effects well interprets asynchronous changes in magnetism and redness in soils and sediments across large spatiotemporal scales, especially in highly weathered soils. Plain Language Summary Iron oxides are critical carriers of magnetism and dyeing agents of soils and sediments. The concentration of pedogenic maghemite (Mgh) and hematite (Hm), which dominate magnetism and redness, is considered to be controlled by the primary iron input and climate conditions. However, phosphate exhibits a high affinity for the surfaces of precursor iron oxides, especially in highly weathered soils. We investigated two Ferralsol sequences around a P mining field with contrasting P/Fe ratios but similar climates. High P/Fe ratios are observed to impede iron oxide crystallization, grain growth, and transformation into Hm, thereby promoting more effective accumulation of ferrimagnetic Mgh as an intermediate product. The presence and absence of ligand-protected effects help explain asynchronous changes in magnetism and color in nature systems across large spatiotemporal scales.
