In vitro digestibility of Urochloa decumbens inoculated with fungi isolated from the gastrointestinal tract of sheep

open access: yesAnnals of Applied Biology, Volume 187, Issue 2, Page 280-289, September 2025.
The forage digestibility decreases in the dry season. Fungus isolates from the gastrointestinal tract of healthy sheep were evaluated. Aspergillus terreus isolate was identified by analysis of rDNA and encoding β‐tubulin gene and Trichoderma longibrachiatum was identified by analysis of rDNA and elongation factor 1‐α gene. The T.

Tracing Oxygen and Hydrogen Isotope Signals From Water Sources to Tree‐Ring Compounds

open access: yesPlant, Cell &Environment, Volume 48, Issue 8, Page 6235-6250, August 2025.
ABSTRACT Stable oxygen (δ18O) and hydrogen (δ2H) isotope compositions of tree‐ring compounds preserve information about environmental waters; however, our understanding of their isotopic relationships is hampered by the lack of long‐term data sets.
