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.

Phytochemical and In Vitro Antibacterial Assessment of Selected Wild Edible Plants From Southwestern Ethiopia

International Journal of Food Science, Volume 2026, Issue 1, 2026.
Background Wild edible plants (WEPs) are vital for food security and traditional medicine, particularly in resource‐limited areas. Despite their potential, their use is constrained by a lack of scientific evidence. This study assesses the phytochemical properties and antibacterial activity of chosen WEPs from southwestern Ethiopia. Method Observational

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 ...
