Chemical Profiling and Biological Activity of Copaiba Oil‐Resin Samples and Development of HPLC‐DAD Method for the Analysis of β‐Caryophyllene

Biomedical Chromatography, Volume 40, Issue 5, May 2026.
ABSTRACT The Copaifera species are traditionally used for their anti‐inflammatory, antiseptic and healing properties. The objective of this study was to compare the chromatographic profiles of seven samples of copaiba oil‐resin with respect to chromatographic and physicochemical properties and to evaluate their biological activities.

Milk Fatty Acid Dynamics in Cows Grazing Standard and Multispecies Pastures Under Two Management Systems

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
This study evaluated the influence of three pasture‐management systems on milk fatty acid (FA) profiles in New Zealand dairy cows: standard–contemporary (STD–CON), diverse–contemporary (DIV–CON), and diverse–regenerative (DIV–REG). The STD–CON pastures consisted of ryegrass–clover, whereas diverse pastures included up to 16 species of grasses, legumes,

Potential to Improve Nitrogen Fertilizer Use Efficiency and Mitigate Pollution in Tropical Pastures Grazed by Sheep

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
We hypothesize that increasing N application rates will affect N use efficiency (NUE) for lambs grazing warm‐season annual grasses. We evaluated the effect of N fertilizer application rates (50, 100, 200, and 400 kg N/ha) on forage pearl millet (Pennisetum glaucum (L.) R.) and animal responses: N balance and NUE per animal and per area basis.

Self‐compatibility in Solanum malmeanum (Solanaceae): Evolutionary and breeding impacts for a novel source of genetic variation in diploid potatoes

TAXON, Volume 75, Issue 2, April 2026.
Abstract Solanum malmeanum, a wild relative of the potato (S. tuberosum), is native to Argentina, Brazil, Paraguay and Uruguay. This wild potato species belongs to the tertiary gene pool (2x = 2n = 24, 1EBN – Endosperm Balance Number) and possesses valuable traits for potato breeding. Understanding its reproductive mechanisms is crucial for effectively

From leaves to defenders: How the amount and dispersion of leaf damage affect extrafloral nectar production and ant‐mediated protection in wild cotton

Ecological Entomology, Volume 51, Issue 2, Page 395-404, April 2026.
Extrafloral nectar mediates interactions among plants, ants and herbivores; its contingency on damage amount and within‐plant uniformity is poorly understood. Here, we explore these factors in wild cotton (Gossypium hirsutum). Herbivory amount drove increases in extrafloral nectar induction per nectary, whereas within‐plant variability in damage ...
