Environment of the Early Pleistocene Banshan Paleolithic Site in the Nihewan Basin, North China

Frontiers in Earth Science, 2022
The Banshan archaeological site is one of the most important Early Pleistocene Paleolithic sites in the Nihewan Basin in North China. Based on analyses of pollen, grain size and charcoal of 56 samples from a sedimentary profile, we reconstructed the ...

Plant sedimentary DNA as a proxy for vegetation reconstruction in eastern and northern Asia

Ecological Indicators, 2021
Plant DNA from sediments (sedDNA) are increasingly used to reconstruct the past vegetation composition, which contrasts with the few investigations on the relationship between the plant sedDNA signal and modern vegetation.

Is there a massive glacial–Holocene flora continuity in Central Europe?

Biological Reviews, Volume 98, Issue 6, Page 2307-2319, December 2023., 2023
ABSTRACT The prevailing paradigm about the Quaternary ecological and evolutionary history of Central European ecosystems is that they were repeatedly impoverished by regional extinctions of most species during the glacial periods, followed by massive recolonizations from southern and eastern refugia during interglacial periods.

Long‐term ecological responses of a lowland dipterocarp forest to climate changes and nutrient availability

New Phytologist, Volume 240, Issue 6, Page 2513-2529, December 2023., 2023
Summary Understanding the long‐term impact of projected climate change on tropical rainforests is critical given their central role in the Earth's system. Palaeoecological records can provide a valuable perspective on this problem. Here, we examine the effects of past climatic changes on the dominant forest type of Southeast Asia – lowland dipterocarp ...

Climate characteristics of the eastern Mongolian Plateau, China during the early Early Cretaceous (145–132 Ma): Palynological evidence from the Tongbomiao Formation in Well Hong-6, Hailar Basin

China Geology, 2022
This study identified two palynological assemblages, namely Bayanhuasporites-Cycadopites-Protoconiferus and Cicatricosisporites-Cedripites-Perinopollenites, in the Tongbomiao Formation in the Hongqi Sag in the Hailar Basin, Inner Mongolia, China for the ...

Biomarker proxies for reconstructing Quaternary climate and environmental change

Journal of Quaternary Science, Volume 38, Issue 7, Page 991-1024, October 2023., 2023
ABSTRACT To reconstruct past environmental changes, a range of indirect or proxy approaches can be applied to Quaternary archives. Here, we review the complementary and novel insights that have been provided by the analysis of chemical fossils (biomarkers). Biomarkers have a biological source that can be highly specific (e.g.

Holocene Vegetation and Plant Diversity Changes in the North-Eastern Siberian Treeline Region From Pollen and Sedimentary Ancient DNA

Frontiers in Ecology and Evolution, 2020
Although sedimentary ancient DNA (sedaDNA) has been increasingly used to study paleoecological dynamics (Schulte et al., 2020), the approach has rarely been compared with the traditional method of pollen analysis for investigating past changes in the ...

Differing local‐scale responses of Bolivian Amazon forest ecotones to middle Holocene drought based upon multiproxy soil data

Journal of Quaternary Science, Volume 38, Issue 6, Page 970-990, August 2023., 2023
ABSTRACT Uncertainty remains over local‐scale responses of ecotonal Amazonian forests to middle Holocene drying due to the scarcity, and coarse spatial resolution, of lacustrine pollen records. This paper examines the palaeoecological potential of soil phytoliths, stable carbon isotopes and charcoal for capturing local‐scale ecotonal responses of ...

Global biome patterns of the Middle and Late Pleistocene

Journal of Biogeography, Volume 50, Issue 8, Page 1352-1372, August 2023., 2023
Abstract Our primary aim was to assess the hypothesis that distinctive features of the patterns of vegetation change during successive Quaternary glacial–interglacial cycles reflect climatic differences arising from forcing differences. We addressed this hypothesis using 207 half‐degree resolution global biome pattern simulations, for time slices ...
