An ashy septingentenarian: the Kaharoa tephra turns 700 (with notes on its volcanological, archaeological, and historical importance) [PDF]

open access: yes, 2014
Most of us are aware of the basaltic Tarawera eruption on 10th June 1886: the high toll on life (~120 people), landscape devastation, and loss of the Pink and White Terraces.

Model simulations and comparison with pollen-based reconstructions [PDF]

open access: yes, 2013
This study is concerned with vegetation modelling in northern Asia and its comparison with pollen-based vegetation and climate reconstructions. With the help of BIOME1, a global biogeographic equilibrium vegetation model, vegetation dynamics during the ...

Late Quaternary Montane Forest Dynamics From Equatorial East Africa: A Biome Perspective

open access: yesJournal of Biogeography, Volume 52, Issue 9, September 2025.
ABSTRACT Aim Understanding environmental change over large spatial and temporal scales requires working at a broad ecological scale to enable cross‐site comparisons. This allows data‐based comparisons to dynamic vegetation model outputs, with utility for climate and land cover modelling.

Ecosystem effects of CO2 concentration: evidence from past climates [PDF]

open access: yes, 2009
Atmospheric CO2 concentration has varied from minima of 170-200 ppm in glacials to maxima of 280-300 ppm in the recent interglacials. Photosynthesis by C-3 plants is highly sensitive to CO2 concentration variations in this range.

Vegetation and environmental dynamics in the central part of the Kola Peninsula during the past 13.3 ka as reflected by ancient plant DNA on sediments from Lake Imandra

open access: yesJournal of Quaternary Science, Volume 40, Issue 6, Page 1070-1096, August 2025.
ABSTRACT The first high‐resolution reconstruction of the vegetation and environmental changes during the last ca 13 300 cal a BP in the central part of the Kola Peninsula (NW Russia) was reconstructed based on sedimentary ancient DNA (sedaDNA) metabarcoding on sediment core Co1410 from Lake Imandra.

The Miocene Bükkábrány Fossil Forest in Hungary – field observations and project outline [PDF]

open access: yes, 2008
The oldest, standing forest preserved as wood has been found at Bükkábrány, Hungary. An open-pit mine working Upper Miocene (Pannonian) lignite revealed sixteen stumps, 1.8 to 3.6 m diameter at base, preserved up to 6 m height, standing on top of the ...

Masked millennial-scale climate variations in South West Africa during the last glaciation [PDF]

open access: yes, 2012
To address the connection between tropical African vegetation development and high-latitude climate change we present a high-resolution pollen record from ODP Site 1078 (off Angola) covering the period 50–10 ka BP.

The Role of Migration in the Change of Northern Hemisphere Vegetation for the Past 50,000 Years

open access: yesJournal of Biogeography, Volume 52, Issue 6, June 2025.
ABSTRACT Aim Our primary aim was to assess how dispersal limitation affected forest changes in the Northern Hemisphere during the last glacial cycle, and especially after the last deglaciation. Location Northern Hemisphere (between 20°N and 80°N). Time Period 50,000–0 years before present. Major Taxa Studied Angiosperms and gymnosperms. Methods We used

Sedimentary ancient DNA from caves: Challenges and opportunities

open access: yesJournal of Quaternary Science, Volume 40, Issue 4, Page 565-578, May 2025.
Abstract Caves are unique depositional environments that hold great potential for long‐term preservation of DNA due to their typically cool and stable internal climates, buffered from external climate extremes. Bones from caves have long been recognised as an excellent source of ancient DNA, yet the potential for DNA preservation in cave sediments ...
