Post‐fire vegetation shifts: Role of invasives and seedbanks in an Australian grassy woodland ecosystem

Journal of Ecology, Volume 114, Issue 4, April 2026.
Wildfire and invasive species interact in a south‐eastern Australian grassy woodland, with the soil seedbank introducing predominantly non‐native species into the extant vegetation after fire. This influx can temporarily increase ecosystem flammability and promote a grass–fire cycle.

Measurement of Ungulate Palatability and Browsing Pressure on Japanese Flora

Ecological Research, Volume 41, Issue 1, January 2026.
Estimation of palatability and browsing pressure are key techniques for ecosystem management. We compared four methods to estimate palatability based on browsing scar survey and proposed the reference palatability values for the Japanese flora as plant ecological trait.

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

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We used DNA metabarcoding of 2,568 fecal samples to examine seasonal diets and resource partitioning among four deer species (moose, roe deer, red deer, fallow deer) across two Swedish landscapes. Deer consumed a wide range of plants, but diets were typically dominated by a few key taxa, with distinct dietary separation between moose and smaller deer ...
