Morphological characterization of biominerals from five multicellular marine algae species

Труды по прикладной ботанике, генетике и селекции, 2020
Silica biominerals are deposited as amorphous solid structures in plant cells and tissues, providing rigidity to different plant parts and assisting in defence. The shape and size of phytoliths are well established and serve as a useful tool in taxonomic

Nano-indentation of native phytoliths and dental tissues: implications for herbivore-plant combat and dental wear proxies [PDF]

Evolutionary Systematics, 2018
Tooth wear induced by abrasive particles is a key process affecting dental function and life expectancy in mammals. Abrasive particles may be plant endogenous opal phytoliths, exogene wind-blown quartz dust or rain borne mineral particles ingested by ...

Phytoliths in particulate matter released by wind erosion on arable land in La Pampa, Argentina

Frontiers in Environmental Science, 2022
Silicon (Si) is considered a beneficial element in plant nutrition, but its importance on ecosystems goes far beyond that. Various forms of silicon are found in soils, of which the phytogenic pool plays a decisive role due to its good availability.

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.

Soil and plant phytoliths from the Acacia-Commiphora mosaics at Oldupai Gorge (Tanzania) [PDF]

PeerJ, 2019
This article studies soil and plant phytoliths from the Eastern Serengeti Plains, specifically the Acacia-Commiphora mosaics from Oldupai Gorge, Tanzania, as present-day analogue for the environment that was contemporaneous with the emergence of the ...

Modern Analog Assemblages of Phytoliths Under Various Plant Communities of the Middle Volga and their Applicability for Archaeological Reconstructions

Поволжская археология, 2021
The article describes the results of investigations of the sub-recent assemblages of silica phytoliths in top soils of various modern plant communities of the Middle Volga region in Tatarstan, Samarskaya and Ulyanovskaya oblasts conducted in 2017–2020 ...

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).

Radiographic Screening of Wild and Semi‐Wild Cape Ground Squirrels (Geosciurus inauris) for the Presence of Peri‐Apical Masses Associated With Elodont Incisor Teeth

Zoo Biology, EarlyView.
Peri‐apical masses were absent in both wild and semi‐wild Cape ground squirrels, despite dietary differences and minor incisor trauma. These findings suggest such lesions are rare outside captivity and not induced by low‐fiber diets alone, adding to the literature on environmental and dietary risk factors in elodont tooth pathology.

Variability of morphometric characteristics of Dactylis glomerata L. (Pooideae Benth.) leaf phytoliths at two stages of the growing season

Acta Biologica Sibirica
The study is devoted to the analysis of the morphometric parameters of Crenate phytoliths of the Dactylis glomerata L. leaf epidermis. The use of morphometry for the nomenclature and identification of phytoliths determines the relevance of studying ...
