A remarkable aspect of the Cretaceous–Paleogene (K–Pg) mass extinction is the resilience of ferns (Orth et al., 1981). Ferns not only withstood the effects of the Chicxulub asteroid impact, which struck the Yucatan Peninsula in Mexico 66 million years ago (Ma), but thrived in its aftermath. Often considered “disaster taxa” (Thomas and Cleal, 2022; Azevedo-Schmidt et al., 2024), ferns are well adapted to thrive after catastrophic events.

Abstract Premise: Leaf epidermal cell morphology is closely tied to plants' evolutionary histories and growth environments, and is therefore of interest to many plant biologists. However, cell measurement can be time-consuming and restrictive with current methods. CuticleTrace is a suite of FIJI and R-based functions that streamlines and automates the segmentation and measurement of epidermal pavement cells across a wide range of cell morphologies and image qualities.
