A drought-driven model for the evolution of obligate apomixis in ferns: evidence from pellaeids (Pteridaceae).

open access: yesAmerican-Eurasian journal of botany, 2021
PREMISE Xeric environments impose major constraints on the fern life cycle, yet many lineages overcome these limitations by evolving apomixis. Here, we synthesize studies of apomixis in ferns and present an evidence-based model for the evolution and ...

Characterization of the Omnivorous Lygus lineolaris Diet in a Strawberry Field by Metataxonomy

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
This study employs metataxonomy to reveal the extensive omnivorous diet of Lygus lineolaris in a strawberry field, identifying 475 host taxa and confirming active ingestion across plant and prey sources. We introduce a novel coefficient of omnivory, demonstrating the species' strong herbivorous bias while highlighting its dietary flexibility and ...
