Natural and anthropogenic forest fires recorded in the Holocene pollen record from a Jinchuan peat bog, northeastern China [PDF]

, 2008
Pollen and charcoal particles from a Jinchuan peat (northeastern China) were examined to investigate the fire origin and interaction between climate, vegetation, fire and human activity during the Holocene.

Holocene sediment dynamics in an upland temperate lake catchment : climatic and land-use impacts. [PDF]

, 2009
Accelerated erosion and transport of fine sediment from upland temperate catchments can reflect increased erosivity and/or erodibility, due in turn to climatic and/or human forcing.

Holocene underkill [PDF]

Proceedings of the National Academy of Sciences, 2008
In this issue of PNAS, Jones et al. (1) address an issue that has been with us, in one way or another, for some 200 years. Around the year 1800, French paleontologist Georges Cuvier established the reality of vertebrate extinction by using animals so large that their future discovery on the hoof was highly unlikely (2).

Evaluation of GPR capabilities in the study of seismogenic faulting and deformation in the bottom sediments of Lake Upoloksha (northeast of the Fennoscandian shield)

Геодинамика и тектонофизика, 2018
The article describes the experience of using the GPR method to study the bottom sediments of Lake Upoloksha located in the Kola Peninsula, Russia. Such sediments are viewed as good archives of various Holocene geodynamic processes, including tectonic ...

Reconstruction of average January temperatures during the early Holocene in the North-East of the Bolshezemelskaya tundra

Лëд и снег, 2020
The aim of the study was to establish the period of accumulation of peatland with ice wedges near Vorkuta town based on series of calibrated radiocarbon dates, to anchor in time the isotope-oxygen curve of syngenetic ice wedge from peatland and to ...

Multiproxy Holocene Fire Records From the Tropical Savannas of Northern Cape York Peninsula, Queensland, Australia

Frontiers in Ecology and Evolution, 2021
Paleoecology has demonstrated potential to inform current and future land management by providing long-term baselines for fire regimes, over thousands of years covering past periods of lower/higher rainfall and temperatures.

Plant Sedimentary Ancient DNA From Far East Russia Covering the Last 28,000 Years Reveals Different Assembly Rules in Cold and Warm Climates

Frontiers in Ecology and Evolution, 2021
Woody plants are expanding into the Arctic in response to the warming climate. The impact on arctic plant communities is not well understood due to the limited knowledge about plant assembly rules.

The Global Stratotype Section and Point (GSSP) for the base of the Holocene Series/Epoch (Quaternary System/Period) in the NGRIP ice core [PDF]

, 2008
The Greenland ice core from NorthGRIP (NGRIP) contains a proxy climate record across the Pleistocene– Holocene boundary of unprecedented clarity and resolution.
