Impact of rice cultivar and organ on elemental composition of phytoliths and the release of bio-available silicon

Frontiers in Plant Science, 2014
The continental bio-cycling of silicon (Si) plays a key role in global Si cycle and as such partly controls global carbon (C) budget through nutrition of marine and terrestrial biota, accumulation of phytolith-occluded organic carbon (PhytOC) and ...

Relationship between phytolith morphology and physical and mechanical properties in bamboo

Industrial Crops and Products
Ferrocalamus strictus is a rare bamboo species native to Yunnan, China, and is notable for its favorable mechanical properties. However, the relationship between phytolith morphology and these properties remains unclear. This study measured nine physical

Soil memory on a toposequence scale: Phytolith and isotopic evidence of paleoenvironmental changes in the Atlantic Forest, Brazil [PDF]

Revista Brasileira de Ciência do Solo
Soils can preserve long-term records of environmental change, providing valuable insights into past vegetation, climate, and landscape changes. This study evaluates soil memory at the toposequence scale using phytolith and carbon-isotope evidence of ...

Comparative phytolith profiles of the weed grasses Echinochloa colona and Echinochloa crus-galli (Poaceae): implications for species taxonomy

Frontiers in Plant Science
IntroductionTaxonomic delimitation of closely related Echinochloa species is frequently complicated by morphological plasticity and overlapping vegetative characters, necessitating complementary diagnostic approaches. This study aimed to evaluate whether

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

Biological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

Biological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Ngarrawa (mound spring) sediments as archives of Holocene environmental change in arid central Australia: Insights from Itrax XRF scanning

Journal of Quaternary Science, EarlyView.
ABSTRACT Central Australia's ngarrawa, or ‘mound springs’, are unique hydrological systems that serve as some of the only near‐permanent sources of water and continuous sediment deposition in Australia's arid interior. As such, they hold significant potential as palaeo‐climate and ‐environmental archives in a region where many aspects of past climate ...

Needle in a haystack: Holocene history of European larch in Central Europe revisited

PLANTS, PEOPLE, PLANET, EarlyView.
Defining nativity of species is crucial for their management. However, this is a complex task, especially for species that have been used and spread by humans for a long time. We combined paleoecological records with extensive genetic data to investigate the Holocene history of European larch—a common and economically important tree species in Central ...

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.

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
