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 ...

Multiple stressors in river networks: local and downstream effects on freshwater macroinvertebrates

open access: yesEcography, Volume 2026, Issue 1, January 2026.
River networks are complex ecosystems characterized by a continuous exchange of material and energy through longitudinal gradients. These ecosystems are threatened by various human‐induced stressors, which frequently co‐occur and may interact in complex ways, potentially triggering cascading effects throughout the river network.
