HOLOCENE ENVIRONMENTAL CHANGE IN SOUTH-EAST ALTAI EVIDENCED BY SOIL RECORD

open access: yesGeography, Environment, Sustainability, 2019
The soils of Russian Altai highlands were used as a paleoenvironmental archive, as a source of dating material, and as a chronostratigraphic marker to describe Holocene environmental change in the studied area. Based on calibration intervals of 14C dates

The NERD Dataset: Near East Radiocarbon Dates between 15,000 and 1,500 cal. yr. BP

open access: yesJournal of Open Archaeology Data, 2022
To our knowledge, the dataset described in this paper represents the largest existing repository of uncalibrated radiocarbon dates for the whole Near East from the Late Pleistocene to the Late Holocene (15,000 – 1,500 cal. yr. BP).

Holocene fire in Fennoscandia and Denmark [PDF]

open access: yesInternational Journal of Wildland Fire, 2014
Natural disturbance dynamics, such as fire, have a fundamental control on forest composition and structure. Knowledge of fire history and the dominant drivers of fire are becoming increasingly important for conservation and management practice. Temporal and spatial variability in biomass burning is examined here using 170 charcoal and 15 fire scar ...

SEA LEVEL AND PALAEOCLIMATIC CHANGES IN THE SOUTH AND MIDDLE CASPIAN SEA REGION SINCE THE LATEGLACIAL FROM PALYNOLOGICAL ANALYSES OF MARINE SEDIMENT CORES

open access: yesGeography, Environment, Sustainability, 2010
A review of pollen, spores, non-pollen palynomorphs and dinocyst analyses made in the last two decades is proposed here. Building on spare palynological analyses before 1990, a series of new projects have allowed taking cores in the deeper parts of the ...

THE EVOLUTION OF CLIMATE AND LANDSCAPES OF THE LOWER VOLGA REGION DURING THE HOLOCENE

open access: yesGeography, Environment, Sustainability, 2010
The results of the palynological analysis and 14C dating of the most complete sequences of the Holocene sediments were used for a detailed reconstruction of multi-cyclic alternations of climate phases and zonal and intrazonal plant formations that were ...

Terrestrial climate variability and seasonality changes in the Mediterranean region between 15 000 and 4000 years BP deduced from marine pollen records [PDF]

open access: yes, 2009
Pollen-based climate reconstructions were performed on two high-resolution pollen marines cores from the Alboran and Aegean Seas in order to unravel the climatic variability in the coastal settings of the Mediterranean region between 15 000 and 4000 ...

Initiation of a Stable Convective Hydroclimatic Regime in Central America Circa 9000 Years BP [PDF]

open access: yes, 2020
Many Holocene hydroclimate records show rainfall changes that vary with local orbital insolation. However, some tropical regions display rainfall evolution that differs from gradual precessional pacing, suggesting that direct rainfall forcing effects ...

Geochemical and sedimentological analyses on the Romanian Sphagnum peat bog Tăul fără fund [PDF]

open access: yesMires and Peat
This study focuses on palaeoenvironmental changes in the Bottomless Lake (Tăul fără fund) Sphagnum peat bog situated near Bǎgǎu in Romania. The central research question was how the lake has changed over time, and how environmental factors and human ...
