Metabarcoding Reveals Fine Scale Patterns of Trophic Resource Use and Partitioning Along Gradients of Land Use and Deer Density in a Multi‐Species Ungulate Community

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.

Nomenclatural notes on some European elm names (Ulmaceae)

open access: yesTAXON, Volume 74, Issue 5, Page 1213-1216, October 2025.
