Brown Bear (Ursus arctos) Field Sign Monitoring for 40 Years (1976–2015) in Northern Hokkaido, Japan, During a Wildlife Management Policy Shift

open access: yesEcological Research, Volume 41, Issue 2, March 2026.
Long‐term (1976–2015) field sign monitoring of brown bears in northern Hokkaido, Japan, yielded 2421 records (feeding signs, tracks, scats) along 9890 km of survey routes. The digitized spatiotemporal dataset provides insights into population dynamics, habitat use, and feeding behavior across a major wildlife management policy shift.

Measurement of Ungulate Palatability and Browsing Pressure on Japanese Flora

open access: yesEcological 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.
