“…Given the estimated time ranges, the oldest dates inferred from genetic studies are compatible with old settlements of modern humans in East Asia attested by fossil or archaeological remains (Fig. 3) (Chen et al 1989;Mijares et al 2010;Shang et al 2007;Shen et al 2002;Sun et al 2000;Vasil'ev 1993;Wu et al 2006). However, ancient molecular lineages may just represent limited heritages of undefined ancestral populations rather than real indications on the origin and migration history of present populations.…”

Population genetic studies may provide crucial information for our knowledge on human peopling history and have been extensively applied to reconstruct East Asian prehistory in the last 10 years. However, different genetic investigations are not always consistent with each other and some results are conflicting or misinterpreted. This represents a main obstacle for scholars of other disciplines like archaeologists and linguists who try to relate the genetic information on past human migrations to their own results on the spread of domesticated crops or animals or on the dispersal of the main language families. In this paper, we review the current genetic evidence related to the peopling history of East Asia with a critical view on some interpretations. In this way, we hope to provide a useful reference for further interdisciplinary studies on our past.

“…Terrestrial records from high altitudes in Java and Sumatra also show that the high elevation vegetation belts in these regions moved down to lower altitudes during the glacial period [8]. Marine records from the southern and northern South China Sea and from northern Australia, show that pollen abundance from tropical montane rainforest taxa was high at the LGM [15][16][17][18]. We found that total pollen concentration was high; probably as a result of vegetation cover on the exposed shelf during lower sea level leading to the vegetation source close to the MD06-3075 core.…”

“…We found that total pollen concentration was high; probably as a result of vegetation cover on the exposed shelf during lower sea level leading to the vegetation source close to the MD06-3075 core. Some support for this hypothesis is provided by the generally much higher total pollen influx in marine cores in the southern South China Sea during the glacial period, when the continental shelves were exposed, than during the interglacial [16]. In addition, the percentage of mangrove taxa was much lower during the glacial; this may indicate that the numbers of mangrove taxa were suppressed, perhaps because the coastline located in steep areas caused as a result of the lower sea level (Figure 1(c)).…”

“…Most of these are muddy rather than sandy or rocky. Climatic factors that affect the distribution of mangroves include changes in sea level, precipitation, and temperature [16,19]. Given that mangroves generally grow between mean sea-level and mean high water, their sedimentary records have been used as both directional and precise sea-level indicators [19][20][21][22].…”

A palynological and palaeoclimatological record from the southern Philippines since the Last Glacial Maximum

A palynological analysis of a marine sediment core in the southern Philippines, provides a detailed regional vegetation and climate history for the West Pacific Warm Pool (WPWP) since the Last Glacial Maximum (LGM). Chronology was determined by a detailed oxygen isotope record. A higher representation of pollen from tropical upper montane rainforest during the LGM indicate that this forest type moved down along elevation, probabaly due to the lowered temperature. During the last deglaciation and the early Holocene, mangroves were more expanded and tropical mid and upper montane rainforests were restricted, suggesting a rising sea-level and temperature increase. Herbaceous pollen and pteridophyte spore records indicate a much drier condition during the LGM than the Holocene. Mangrove development is controlled by conditions at the river mouth influenced by river discharge. Pteridophyte spores are abundant in wet conditions and are mainly transported by rivers. During the mid-Holocene, the reduction in mangrove pollen and pteridophyte spore appears to be a result of climate change: mainly decrease in river discharge. This may have been affected by the decreasing intensity of the Southeast Asian Monsoon, and the increasing frequency and intensity of warm ENSO events, El Niño, in this region.Last Glacial Maximum, tropical rainforests, palynological analyses, sea-level change, river discharge Citation:Bian Y P, Jian Z M, Weng C Y, et al.

“…They proposed that it is today's rainforests that are refugial and not those of, for example, the LGM. To date, some findings suggest that animal populations extend their distribution to cope with the LGM, as supported by pollen analysis of river and offshore sediments from the South China Sea [49,50]. Hainan Island has experienced connections and disconnections with the mainland of China, Taiwan Island and the Indo-China Peninsula due to sea level fluctuations throughout the late Pleistocene [10].…”

Molecular demographic history of the Hainan Peacock Pheasant (Polyplectron katsumatae) and its conservation implications

Knowledge of the historical responses of animal species to climate changes is critical for understanding their evolutionary history and conservation. During the late Quaternary period, Southeast Asia had a larger land area than today due to lower sea levels, and its terrestrial landscape was covered by extensive forests and savannah. To date, however, the general fluctuations in landscape distribution and their impacts on the demographics history of native species during the late Quaternary periods are still disputed. Specifically, the responses of animals on Hainan Island, which is located in the northernmost region of Southeast Asia, to historical climate changes, are poorly understood. Here, we performed a series of demographic analyses based on mitochondrial DNA genes to examine the response of the resident Hainan Peacock Pheasant (Polyplectron katsumatae) to climate change. Unlike the pattern of population collapse during the ice age and expansion during the warming period, we detected a historical expansion pattern in the demographic history of Hainan Peacock Pheasant through the late Quaternary period. It was concluded that the Hainan Peacock Pheasant survived through the late Quaternary periods, despite of its currently limited distribution and population size on Hainan Island. Anthropogenic influences must be considered in conservation planning due to their impacts on currently fragmented habitats and populations. phylogeography, Quaternary, Hainan Island, Polyplectron katsumatae, conservation Citation:Chang J, Chen D, Liang W, et al.
