Carbon stable isotope analysis of cereal remains as a way to reconstruct water availability: preliminary results [PDF]

, 2011
Reconstructing past water availability, both as rainfall and irrigation, is important to answer questions about the way society reacts to climate and its changes and the role of irrigation in the development of social complexity.

Phytolith Content Negatively Affects Forage Quality of Eragrostis curvula (Schrad.) Nees

Agronomy, 2023
Phytoliths are intra and extracellular siliceous deposits present in different plant tissues. Si uptake and transport are mediated by Lsi genes and its concentration is associated with forage quality.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Miocene phytolith and diatom dataset from 10.3Myo diatomite formation, Fernley, Nevada, USA

Data in Brief, 2023
Phytoliths are opal silica particles formed within plant tissues. Diatoms are aquatic, single-celled photosynthetic algae with silica skeletons. Phytolith and diatom morphotypes vary depending on local environmental and climatic conditions and because ...

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.

Carbon sequestration law by phytoliths in the bamboo forests: Insights for the management of phytolith carbon sink

Global Ecology and Conservation
Phytolith-occluded organic carbon (PhytOC) plays a crucial role as a stable and enduring carbon sink in the intricate web of terrestrial ecosystems. Bamboo forests exhibit the most prominent ability of phytolith carbon sequestration among terrestrial ...

Production of carbon occluded in phytolith is season-dependent in a bamboo forest in subtropical China.

PLoS ONE, 2014
Carbon (C) occluded in phytolith (PhytOC) is a stable form of C; when PhytOC is returned to the soil through litterfall it is stored in the soil which can be an effective way for long-term C sequestration.
