Fire, climate and the origins of agriculture: micro-charcoal records of biomass burning during the Last Glacial Interglacial Transition in Southwest Asia [PDF]

, 2010
This study investigates changes in climate, vegetation, wildfire and human activity in Southwest Asia during the transition to Neolithic agriculture between ca. 16 and ca. 9 ka.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.

Phytolith data in peat profile over the past 1300 years in the Xishan Mountains, Jiangxi Province, China

Data in Brief, 2019
Phytoliths are microscopic siliceous particles formed in the plants and preserved in the sediments after the plant death and decay. Phytolith formation is controlled by the plant genes and growing environments.

The onset of grasses in the Amazon drainage basin, evidence from the fossil record [PDF]

, 2020
Poaceae (the grass family) originated in the Cretaceous, but first dominate the palynological records of the Amazon drainage basin (ADB) in the Neogene (23 to 2.5 million years ago (Ma)).

Graman Revisited Once Again: A Reanalysis of the Late Holocene Legacy Faunal Assemblage From GB4 Rockshelter, New South Wales

Archaeology in Oceania, EarlyView.
ABSTRACT The archaeological site Graman B4 provided one of the first records of substantial dietary change in ancient Australian Aboriginal society. Initial examination of the faunal remains from this site suggested that Late Holocene hunters reduced their focus on high‐ranked kangaroos to increasingly rely on arboreal possums; and that these ...

Marine silicon for biomedical sustainability

BMEMat, EarlyView.
Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.

Using [delta] ph as a geochemical index of illite neoformation in saprolite [PDF]

, 2008
Sal pH is routinely measured for agronomic purposes. When the difference between KCI pH and H2O pH, or ApH, yields positive values, it is used by soil scientists as a classification criterion for identifying anionic subgroups according to the Soil ...

Fossil pollen records reveal a late rise of open-habitat ecosystems in Patagonia [PDF]

, 2012
The timing of major turnovers in terrestrial ecosystems of the Cenozoic Era has been largely interpreted from the analysis of the assumed feeding preference of extinct mammals. For example, the expansion of open-habitat ecosystems (grasslands or savannas)

Could large‐scale silicon supplementation of crop‐lands mitigate the impacts of climate change?

PLANTS, PEOPLE, PLANET, EarlyView.
Intervention strategies that involve supplementing crop‐lands with silicon have significant scope for carbon capture and drought mitigation, offering wide‐ranging societal impacts. These include contributing to decarbonisation goals, enhancing food security, providing economic benefits and reducing environmental damage associated with intensive ...
