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

open access: yesJournal 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 ...

Using the fossil flora composition analysis for the reconstruction of vegetation and palaeoecological conditions during late glacial time in Karelia

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018
The paper summarizes the results of pollen and macrofossil studies of late glacial deposits in Karelia, encompassing the Older Dryas, Allerod, and Younger Dryas – 12350–10300 14С yrs BP (14100–11900 cal. yrs BP).

Paleovegetation and paleoclimate in the Baise Basin during Oligocene

open access: yes地质科技通报, 2022
To reconstruct the palaeovegetation and palaeoclimate in the Baise Basin during the Oligocene, in this work, we analyzed sporopollen fossils from the Fuping Formation in this region.

Palaeovegetation and palaeoclimate changes across the Triassic–Jurassic transition in the Sichuan Basin, China

open access: yesPalaeogeography, Palaeoclimatology, Palaeoecology, 2020
Abstract The Triassic–Jurassic transition interval is marked by enhanced biotic turnover rates in both marine and terrestrial realms. However, limited data from Asia hampers the understanding of global ecosystem response to the end-Triassic mass extinction event. Here, we present significant vegetation and climate changes across the Triassic–Jurassic

The stable isotope setting of Australopithecus sediba at Malapa, South Africa

open access: yesSouth African Journal of Science, 2016
We report δ13C and δ18O results from carbonate-cemented cave sediments at Malapa in South Africa. The sediments were deposited during a short-period magnetic reversal at 1.977±0.003 Ma, immediately preceding deposition of Facies D sediments that contain ...

Vegetation dynamics in the Kostomuksha State Nature Reserve (Russia) and surroundings against changes in the natural environment during the Holocene

open access: yesNature Conservation Research: Заповедная наука, 2021
In the current situation of climate instability, research on the natural trends of vegetation development against global climate change is of high relevance, especially in areas once covered by the latest glaciation (Weichselian), and not altered ...
