Dental calculus evidence of Taï Forest Chimpanzee plant consumption and life history transitions [PDF]

, 2015
Dental calculus (calcified dental plaque) is a source of multiple types of data on life history. Recent research has targeted the plant microremains preserved in this mineralised deposit as a source of dietary and health information for recent and past ...

Bulliform Phytolith Size of Rice and Its Correlation With Hydrothermal Environment: A Preliminary Morphological Study on Species in Southern China [PDF]

Frontiers in Plant Science, 2019
En la última década, nuestra comprensión de la domesticación del arroz ha mejorado con nuevos hallazgos arqueológicos que utilizan técnicas analíticas avanzadas, como análisis morfológicos y morfométricos en granos de arroz, bases de espiguillas y fitolitos, y análisis de ADN antiguo en restos de arroz. Estudios previos han considerado el tamaño de los

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.

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.

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.

Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.
