On-site plant-wax biomarker analysis for assessing soil-organic-microbial degradation in archaeological contexts: A case study from Southern India [PDF]

iScience
Summary: Stable carbon isotope (δ13C) analysis of soil organic matter (SOM) from archaeological contexts is widely employed as a proxy for palaeovegetation and palaeoenvironmental reconstruction.

Environmental conditions do not predict diversification rates in the Bantu languages [PDF]

Heliyon, 2019
The global distribution of language diversity mirrors that of several variables related to ecosystem productivity. It has been argued that this is driven by the size of social networks, which tend to be larger in harsher climates to ensure food security,

Response of spatial vegetation distribution in China to climate changes since the Last Glacial Maximum (LGM). [PDF]

PLoS ONE, 2017
Analyzing how climate change affects vegetation distribution is one of the central issues of global change ecology as this has important implications for the carbon budget of terrestrial vegetation.

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.

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 ...

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.
