Limited contribution by non‐volant small mammals to regeneration in ironstone rocky outcrops

Restoration Ecology, EarlyView.
Abstract Introduction Animal‐mediated seed dispersal contributes substantially to natural regeneration in degraded areas. However, the role of seed dispersal by non‐volant small mammals (NVSM), mainly marsupials and rodents, in contributing to regeneration remains underexplored, especially in mountaintop, open‐canopy ecosystems.

Assessment of Metabolites in Noni Fruit Slurry Fermented With Four Non‐Saccharomyces Yeasts

Food Frontiers, Volume 7, Issue 2, March 2026.
Dried noni fruit slurry (DNFS) was fermented for 14 days with selected non‐Saccharomyces yeasts. GCMS, HPLC and amino acid analysis showed that Pichia kluyveri Frootzen and Williopsis saturnus NCYC22 grew well, reduced off‐flavor fatty acids, generated fruity aroma compounds and preserved total phenolic content. ABSTRACT Noni products often suffer from
