Morphometric analysis reveals deep-time phylogenetic signals in grass phytolith shapes across 73 extant species, highlighting their value for quantitative paleoecological reconstructions.

Key Points

To evaluate how phylogenetic diversification, ecological factors, and intraindividual variability shape grass silica short cell phytolith morphology.
Evaluated 3,650 two-dimensional outlines representing the intraindividual phytolith shape variation across 73 extant grass species, 48 genera, 18 tribes, and eight subfamilies, with a primary focus on Pooideae.
Applied geometric morphometrics using semi-landmarks distributed along 2-D outlines to quantify shape variation.
Two-dimensional phytolith shape is primarily driven by deep-time evolutionary diversification across grass subfamilies.
Early-diverging lineages of Pooideae, specifically Meliceae and Stipeae, display distinct and identifiable phytolith shape profiles.
Intraindividual variation in phytolith shape differs systematically among species, establishing a clear phylogenetic pattern across grass lineages.
