The Impact of Geomorphological Settings and Environmental Influences on Crop Utilization in the Mid-to-Late Neolithic Period in Shaanxi Province, Northwest China

Land
During the Middle-to-Late Neolithic period (7000–3800 BP), Shaanxi Province served as a critical juncture in the transmission of crops. Foxtail millet (Setaria italica), broomcorn millet (Panicum miliaceum), and rice (Oryza sativa) spread westwards into ...

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

Transactions 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).

Could clonality contribute to the northern survival of grey alder [Alnus incana (L.) Moench] during the Last Glacial Maximum?

Acta Societatis Botanicorum Poloniae, 2016
Reconstruction of the glacial and postglacial history of a species, including life-history traits, provides valuable insights into the relationships between ecological and genetic factors shaping phylogeographic patterns.

Fossil trees, tree moulds and tree casts in the Palaeocene Mull Lava Field, NW Scotland: context, formation and implications for lava emplacement [PDF]

, 2016
Megafossils and macrofossils of terrestrial plants (trees, leaves, fruiting bodies, etc.) are found in sedimentary and pyroclastic units interbedded with lavas in many ancient lava fields worldwide, attesting to subaerial environments of eruption and the

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

People and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Eastern Beringia and beyond: Late Wisconsinan and Holocene landscape dynamics along the Yukon Coastal Plain, Canada [PDF]

, 2012
Terrestrial permafrost archives along the Yukon Coastal Plain (northwest Canada) have recorded landscape development and environmental change since the Late Wisconsinan at the interface of unglaciated Beringia (i.e.

Living by the lake: Plant food diversity in a prehistoric lake‐dwelling community in the Republic of North Macedonia

Archaeometry, EarlyView.
Abstract This paper explores the relationship between wetland ecosystems and prehistoric lakeshore settlements within the Lake Ohrid basin (a biodiversity hotspot) by considering plant food systems at Ploča Mičov Grad, North Macedonia. The mid‐fifth millennium (c.4555–4373 to 4437–4241 cal BCE) waterlogged assemblage contained a diverse spectrum of ...

The 2.1 Ga old Francevillian biota: biogenicity, taphonomy and biodiversity. [PDF]

PLoS ONE, 2014
The Paleoproterozoic Era witnessed crucial steps in the evolution of Earth's surface environments following the first appreciable rise of free atmospheric oxygen concentrations ∼2.3 to 2.1 Ga ago, and concomitant shallow ocean oxygenation.

Untangling nutrient co‐regulation of ombrotrophic peatland development

Boreas, EarlyView.
Multi‐method (FTIR, FT‐NIR and TGA) approaches characterizing the organic peat constituents at Holcroft Moss reveal a record of switches that reflect broadly hydroclimate variability governing the decomposition patterns. There are periods, however, where hydroclimate does not fully explain the variability observed and instead changes appear linked to ...
