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.

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.

Comparison of Phytolith Characteristics of Three Bamboo Species’ Cotyledon Organs

Plants
Phytoliths are widely used in plant taxonomy, paleoecology, soil silicon cycling, and agricultural archaeology. Bamboo has a strong capacity for silicon absorption, and there are some phytoliths in various organs.

Soil Silicon Application Alleviates Drought Stress in Sugar Beet (Beta vulgaris L.)

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: The increasing frequency and intensity of drought events have led to yield and quality losses in sugar beet production in temperate regions in Central Europe. Under arid conditions, silicon (Si) application reduced beet yield losses under drought. Similar data for temperate climates are missing.

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 ...

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

A recipe for recovery: diet as a decisive tool in species conservation

Oikos, EarlyView.
Animals consume foods in specific quantities and ratios to meet a multi‐dimensional nutrient target that maximizes their fitness. Attempts to reach this target in an ever‐changing nutritional landscape often influence animal foraging behavior, habitat choice, and food‐web interactions. Consequently, understanding the nutritional ecology of a species is

Aluminum in the opal silica reticule of phytoliths: a new tool in palaeoecological studies [PDF]

, 2002
X-ray microanalysis was employed to screen biogenic plant silica extracted from the aboveground tissues of 20 species (Gramineae, Cyperaceae, Ericaceae, and Coniferae) occurring in subalpine and alpine grasslands, heaths, and woodlands on siliceous ...

CO2 can decrease the dissolution rate of ashed phytoliths

, 2021
Phytoliths are silica structures formed in various silicon (Si)-rich plant species. These structures are a fast-reacting source of available Si for soils and crops and act as a platform for the sequestration of organic matter and CO2.
