Herbivory is fundamental in ecology, being a major driver of ecosystem structure and functioning. Plant Si and phytoliths play a significant antiherbivory role, the understanding of which and of its evolutionary context will increase our understanding of this phenomenon, its origins, and its significance for past, extant, and future ecosystems. To achieve this goal, we need a superdisciplinary evolutionary framework connecting the role of Si in plant–herbivore interactions, in global processes… Expand

Silicon in the Soil–Plant Continuum: Intricate Feedback Mechanisms within Ecosystems
It is shown that Si uptake and accumulation by plants is involved in several ecosystem services like soil appropriation, biomass supply, and carbon sequestration, and should be the main focus of future research. Expand


Functions of phytoliths in vascular plants: an evolutionary perspective
Mapping analysis indicates that active silica accumulation evolved numerous times, rather than being ancestral in land plants, and finds no convincing evidence for Cenozoic grass-grazer co-evolution. Expand
Is plant ecology more siliceous than we realise?
An ecological perspective to research outcomes from diverse disciplines is provided, showing that silicon is an important element in plant ecology that is worthy of greater attention. Expand
The ecology of herbivore‐induced silicon defences in grasses
Current knowledge of silicon mediation of plant–herbivore interactions in an ecological context is reviewed, highlighting new research areas to address what still remains unclear about the role of silicon as a plant defence, particularly in relation to plant– herbivores interactions in the field, where the effects of grazing on defence induction are harder to measure.

Grasshoppers may speed up nitrogen cycling by changing the abundance and decomposition rate of plant litter, which increases total plant abundance, and whether grasshoppers enhance plant abundance depends on how much they consume. Expand

AbstractPurpose When studying the effects of environmental variables on plant Si contents, results of laboratory and field experiments do not always agree with each other. However, new insights intoExpand
The role of the Levant in 135 million years of angiosperm evolution: a review
The Levant's biogeographic setting also makes it a palaeobiologically significant location, as will be demonstrated here for the past 135 million years of plant evolution, which corroborates that biotic evolutionary drivers are stronger and more apparent at small spatial, temporal and taxonomic scales, whereas abiotic evolutionary drivers is stronger andMore apparent at larger scales.

Tradeoffs between foliar silicon and carbon‐based defences: evidence from vegetation communities of contrasting soil types
The results suggest that tradeoffs exist between phenolic- and tannin-based defences and provide evidence that leaf silicification may be a more effective defence against some chewing herbivore groups than others. Expand
