Integrated Plant Record (IPR) vegetation analysis is a semi-quantitative tool developed as a proxy to assess zonal vegetation classification. It is based on fossil plant taxa categorized into zonal taxonomic-physiognomic components reflecting key autecological characteristics. The proportions of these components in the fossil assemblages define the main vegetation types. Modern vegetation studies in areas of South China (Mount Emei, Mount Longqi, Meili Snow Mountains) and in Japan (Shirakami Sanchi, Mount Fuji, Nara, Yokohama, Yakushima Island) are performed here to test this fossil-based technique and achieve fine-tuning and corroboration. Thirty-five units of different vegetation types generally defined as broad-leaved evergreen forests, mixed mesophytic forests, broad-leaved deciduous forests, and subhumid sclerophyllous forests were investigated. IPR vegetation analysis results obtained from this modern vegetation largely support the originally defined proportions of the important zonal woody angiosperm groups, i.e., broad-leaved deciduous, broad-leaved evergreen, sclerophyllous, and legume-type components, and cluster analysis also confirms these results. Nonetheless, the data suggest that the new definition of ecotones and adaption of the threshold value of the broad-leaved evergreen component for the definition of broad-leaved evergreen forests are necessary. The results of this study of modern vegetation reveal a distinct underrepresentation of zonal herbs in the fossil record, regardless of whether dealing with leaf, pollen, or fruit assemblages. The vegetation scheme based on IPR vegetation analysis is therefore extended to properly reflect the zonal herb diversity present in modern vegetation. The results also confirm a higher diversity of zonal herbs in modern broad-leaved deciduous versus broad-leaved evergreen forests, as observed in the Neogene European record.

Large-scale phytogeographical patterns in East Asia in relation to latitudinal and climatic gradients2003 •
Aim This paper aims at determining how different floristic elements (e.g. cosmopolitan, tropical, and temperate) change with latitude and major climate factors, and how latitude affects the floristic relationships between East Asia and the other parts of the world.Location East Asia from the Arctic to tropical regions, an area crossing over 50° of latitudes and covering the eastern part of China, Korea, Japan and the eastern part of Russia.Methods East Asia is divided into forty-five geographical regions. Based on the similarity of their world-wide distributional patterns, a total of 2808 indigenous genera of seed plants found in East Asia were grouped into fourteen geographical elements, belonging to three major categories (cosmopolitan, tropical and temperate). The 50°-long latitudinal gradient of East Asia was divided into five latitudinal zones, each of c. 10°. Phytogeographical relationships of East Asia to latitude and climatic variables were examined based on the forty-five regional floras.Results Among all geographical and climatic variables considered, latitude showed the strongest relationship to phytogeographical composition. Tropical genera (with pantropical, amphi-Pacific tropical, palaeotropical, tropical Asia–tropical Australia, tropical Asia–tropical Africa and tropical Asia geographical elements combined) accounted for c. 80% of the total genera at latitude 20°N and for c. 0% at latitude 55–60°N. In contrast, temperate genera (including holarctic, eastern Asia–North America, temperate Eurasia, temperate Asia, Mediterranean, western Asia to central Asia, central Asia and eastern Asia geographical elements) accounted for 15.5% in the southernmost latitude and for 80% at 55–60°N, from where northward the percentage tended to level off. The proportion of cosmopolitan genera increased gradually with latitude from 5% at the southernmost latitude to 21% at 55–60°N, where it levelled off northward. In general, the genera present in a more northerly flora are a subset of the genera present in a more southerly flora.Main conclusions The large-scale patterns of phytogeography in East Asia are strongly related to latitude, which covaries with several climatic variables such as temperature. Evolutionary processes such as the adaptation of plants to cold climates and current and past land connections are likely responsible for the observed latitudinal patterns.

Climatic Change
Holocene vegetation and climate history at Haligu on the Jade Dragon Snow Mountain, Yunnan, SW China2012 •
This paper uses pollen analysis to investigate and document the changing climate and vegetation during the Holocene based on a 400 cm core in depth obtained at a wetland site at Haligu (3,277 m a. s. l.) on the Jade Dragon Snow Mountain in Yunnan, China. By applying the Coexistence Approach to pollen data from this core, a quantitative reconstruction of climate over the last 9,300 years was made based on each pollen zone and individual core sample, which reveals the temperature and precipitation change frequently during that time. The qualitative analyses show that from 9300 to 8700 cal. yr BP, the vegetation was dominated by needle-leaved forest (mainly Pinus and Abies), indicating a slightly cool and moderately humid climate. Between 8700 and 7000 cal. yr BP, evergreen broad-leaved forest, dominated by Quercus, became the predominant vegetation type, replacing needleleaved forest at this elevation, implying a warmer and more humid climate. During the period 7000 to 4000 cal. yr BP, the vegetation changed to mixed needle-leaved and evergreen broad-leaved forest, indicating a warm and moderately humid climate, but somewhat cooler than the preceding stage. From 4000 to 2400 cal. yr BP, the vegetation was again dominated by evergreen broad-leaved forest, but coniferous trees (mainly Pinus) began to increase, especially relative to a decline in Quercus. This implies that the climate remained warm and humid but slight drier than previously. The evergreen Quercus phase (8700–2400 yr BP) was designated as the Holocene climatic optimum in the Haligu core sediments. It is correlated with a markedly greater abundance and diversity of pteridophytes spores than was recorded before or after this period. From 2400 cal. yr BP to present, the vegetation was dominated by needle-leaved forest, of which Pinus formed the predominant component, accompanied by Abies and Tsuga. This reflects a slightly cooler, humid climate but also correlates with a period of increasing human settlement on the lower slopes of the mountain. At this elevated site, several hundred metres above the highest present day settlements, direct palynological evidence of anthropogenic activity is uncertain but we discuss ways in which the marked decline in Quercus pollen during this period may reflect the impact of ways in which natural resources of the mountain have been utilised.
