Patterns of ferns community assemblages in some Malaysian and Nigerian tropical forests

open access: yesEcology and Evolution, Volume 12, Issue 6, June 2022., 2022
The study assessed the patterns of ferns species richness (SR) and phylogenetic diversity (PD) in relation to the bioclimatic drivers in some Nigerian and Malaysian forests. Fern species richness and diversity is significantly higher in Malaysian forests than in Nigerian forests.

Pteridium aquilinum (Dennstaedtiaceae), a Novel Hyperaccumulator Species of Hexavalent Chromium

open access: yesApplied Sciences, 2023
Hexavalent chromium (Cr VI) is a highly toxic environmental pollutant produced as a byproduct of stainless steel manufacture and leather tanning. Several vegetal Cr VI-accumulating species have been investigated in phytoremediation, a promising technology to remove heavy metals from soils and water bodies.

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.

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.
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 ...
