Tracking Ungulate Diet: Comparing Observational and DNA Metabarcoding Tools

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
Our study evaluates the diets of large mammalian herbivores by comparing traditional observations with DNA metabarcoding analyses of plants and plant‐dwelling arthropods. While plant DNA metabarcoding reliably identifies dietary preferences, arthropod‐derived plant information is less accurate compared to traditional methods.

Contribution of awns and hairy glumes in spring wheat to resistance against wheat midge, Sitodiplosis mosellana

open access: yesEntomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 781-793, July 2025.
Wheat morphological traits had no consistent impact on Sitodiplosis mosellana oviposition. Differences in the number of eggs among doubled haploid wheat lines were not associated with the presence (A+) or absence (A−) of awns, or the presence (H+) or absence (H−) of hairs in controlled laboratory experiments and field trials.
