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.

Water availability and evolutionary similarity shape the global distribution of ferns with chlorophyllous spores

open access: yesEcography, Volume 2025, Issue 11, November 2025.
About 14% of all fern species have chlorophyllous spores, which lack dormancy, have thin walls, and have a shorter viability (only a few days in some species). These spores should have limited dispersal distances and be more susceptible to harsher climatic conditions, raising questions about the evolutionary and ecological significance of this trait ...
