The Reconstruction of Paleovegetation and Paleoclimate in the Late Pliocene of West Yunnan, China

Abstract

Abstract. The Eryuan palynoflora from the Late Pliocene of western Yunnan, China is described in this paper, and is compared with two contemporary palynofloras from Yangyi and Longling.

Resolving phylogenetic relationships and species delimitations in closely related gymnosperms using high-throughput NGS, Sanger sequencing and morphology

“…These transitions should have facilitated speciation and geographic expansion in the Chinese lianoid clade of Gnetum and may explain the largely overlapping geographic distribution of extant species. From the Pliocene, the climate gradually became cooler and drier (Ravelo et al 2004;Xu et al 2004;Kou et al 2006) (Fig. 5b), and based on the long stem lineages to several of the extant species, it seems possible that extinction affected the clade during the late Miocene and Pliocene.…”

Early Paleocene vegetation and climate in Jiayin, NE China

“…We also consulted the database of PALAEOFLORA Mosbrugger 1990-2007) in deciding the MAT of NLRs. The climatic tolerances of the NLR were obtained from the climatic records within their modern distributional areas (Wu and Ding 1999;Kou et al 2006;Ecroyd 1982;Tsukada 1963;McFarland 1949;Tsumura et al 1999;Wilhite and Toliver 1990;Kunzmann 2007).…”

The history of vegetation and climate changes of Yunnan in response to the uplift of Tibetan Plateau during the Neogene

“…In Asian, regional climate and environment changed profoundly by the uplift of Tibetan Plateau [1,2,3,4,5,6]. The uplift of Tibetan Plateau gradually influenced the basic pattern of the atmospheric circulation in the northern hemisphere, triggered the onset of the Asian monsoon system, and become an important climate factor affecting the environmental change and biological evolution in Asia [7].…”

“…The unique geographical position, special climate condition and abundant botanical resources make Yunnan one of the most important regions for studying the climate and vegetation changes caused by uplift of the Tibetan Plateau [32,33,34,35]. In recent years, a series of similar quantitative researches on the Neogene climate in Yunnan have been accumulating since the 2000s [5,30,33,34,35,36,37]. Xu [36] described the Late Pliocene palynofloras of Eryuan, Yangyi and Longling, western Yunnan and respectively quantitative reconstructed the climates of three localities.…”

“…Zhao et al [37] reported plant megafossils from the Early-Middle Miocene Nanlin Formation of the Mangdan coal-mine, including 11 taxa of angiosperms, Corylopsis, Ficus, Hypericum, Lauraceae, Lithocarpus, Magnolia, Myrica, Nyssa, Sabia, Symplocos and Zanthoxylum, suggesting an evergreen broad-leaved forest growing in Mangdan region. Kou et al [5] recorded the pollen assemblages from Eryuan during the Late Pliocene of western Yunnan, and compared those with two contemporary palynofloras from Yangyi and Longling. They suggested the palaeotemperature was higher than present among three localities while the a doubling of the palaeoprecipitation in the Longling area between the Late Pliocene and the present.…”
