Phytolith Characteristics in Leaves and Culm Sheaths of Three Sympodial Bamboo Genera (Bambusoideae) in the Xishuangbanna Tropical Botanical Garden, China

Agronomy
This study focused on the phytolith characteristics of leaves and culm sheaths from nine bamboo species across three genera (Bambusa Schreb., Gigantochloa Nees, and Dendrocalamus Kurz ex Munro) in the Xishuangbanna Tropical Botanical Garden. By analyzing

Silicofitolitos : aplicaciones para la reconstrucción de los sistemas de subsistencia prehistóricos [PDF]

, 2005
En Uruguay, el análisis de silicofitolitos comienza a implementarse en la década de 1990 como una técnica alternativa para el abordaje del registro arqueobotánico, hasta entonces poco explorado dada la mala preservación de restos orgánicos. El desarrollo

Nickel Effects on Growth and Phytolith Yield of Grasses in Contaminated Soils

Soil Systems
Nickel (Ni) is extremely toxic to plants at high concentrations. Phytoliths have the potential to sequester the heavy metals absorbed by plants and act as a detoxification mechanism for the plant.

The Biogeochemical Cycle of Silicon and Its Role During the Formation of an Aquaculture Carbon Sink

Progress in Fishery Sciences
In the context of global climate change, one central interest is an improved understanding of the global carbon cycle. A large number of studies have investigated carbon cycling and associated elements, mainly nitrogen and phosphorus.

Molecular Dating, Evolutionary Rates, and the Age of the Grasses [PDF]

, 2017
Many questions in evolutionary biology require an estimate of divergence times but, for groups with a sparse fossil record, such estimates rely heavily on molecular dating methods.

New discovery of the oldest maize weevils in the world from Jomon potteries, Japan [PDF]

, 2010
The maize weevil (_Sitophilus zeamais_) and rice weevil (_Sitophilus oryzae_) are two of the most damaging insects for stored grains, and are characteristic species of ancient Japan. Both species and the granary weevil (_Sitophilus granarius_) are common

Phytolith-Mediated Biocarbon Sequestration

International Journal of Plant & Soil Science
The sequestration of biocarbon primarily arises from natural mechanisms and is acknowledged as a critical measure in mitigating climate change. An inactive form of carbon, known as phytolith occluded carbon, is sequestered within plants and persists in soil for thousands of years following the breakdown of vegetation.
