Evaluating the Quantitative Accuracy and Application of DNA Metabarcoding for Dietary Reconstruction in Ruminants

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This study assessed the accuracy of DNA metabarcoding using ITS2 and trnL markers to reconstruct sheep diets under controlled feeding trials with high‐ and low‐digestibility forage, and in a secondary trial with low‐level inclusions of Medicago sativa. ITS2 offered higher species‐level resolution, while trnL provided broader taxonomic coverage but less

Regenerative Management and Phosphorus Fertiliser Effects on Dryland Pasture Yield and Botanical Composition in New Zealand

Grass and Forage Science, Volume 81, Issue 1, January-March 2026.
ABSTRACT This 3.5‐year grazed farmlet study investigated the impacts of regenerative agriculture and soil phosphorus (P) fertiliser on herbage dry matter (DM) yield and botanical composition in sheep‐grazed dryland pastures. Four treatments compared regenerative with conventional agriculture, under high and low P fertiliser, with Olsen P targets of 10 ...
