Biological Protein Value of Pteridium aquilinum (L.) Kuhn

open access: yesТехника и технология пищевых производств, 2022
Contemporary human diet is poor in proteins. Therefore, the modern food science should find new sources of high-grade protein. The bracken fern is rich in proteins can be an unconventional solution to this problem. The research objective was to study the

Selenium reverses Pteridium aquilinum-induced immunotoxic effects

open access: yesFood and Chemical Toxicology, 2011
We have previously shown that bracken fern (Pteridium aquilinum) has immunomodulatory effects on mouse natural killer (NK) cells by reducing cytotoxicity. Alternatively, it has been demonstrated that selenium can enhance NK cell activity. Therefore, the aims of the present study were to evaluate if ptaquiloside, the main toxic component found in P ...

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.

Intraspecific Trait Variation Drives Functional Shifts in Grass Communities Under Grazing in the Scottish Uplands

open access: yesJournal of Vegetation Science, Volume 37, Issue 1, January/February 2026.
Shifting grazing regimes alter grasslands, however the relative roles of species turnover versus intraspecific variation (ITV) underpinning trait change are poorly understood. Using a 20‐year grazing experiment in the Scottish uplands,we found that grazing‐driven functional change in grass communities are primarily driven by ITV rather than species ...

The life cycles of cryptogams [PDF]

open access: yes, 1991
Meiosis and karyogamy are recognized as control points in the life cycle of cryptogams. The control of meiosis is evidently complex and in yeast, and by analogy in all cryptogams, involves progressive gene activation.

Grazing Intensity Shapes Vegetation Structure and Soil Characteristics in High‐Elevation Rangelands of Nepal

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study assessed the impacts of four grazing intensities—non‐grazed (NG), lightly grazed (LG), moderately grazed (MG), and highly grazed (HG)—on plant species diversity, community composition, plant height, biomass production, and soil physicochemical properties across three sub‐alpine rangelands in Jumla district, western Nepal. Our results support
