Agronomic Traits, Physiological Parameters, Chemical Composition, and In Vitro Digestibility of Urochloa Brizantha Cv. Piatã, Megathyrsus Maximus Cv. Zuri and Megathyrsus Maximus Cv. Tamani in Silvopastoral Systems

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Urochloa species are widely used in silvopastoral systems (SPS), but production losses highlight the need for more productive forages. This study evaluated agronomic, physiological, chemical composition, and in vitro digestibility responses of Urochloa brizantha cv. Piatã and Megathyrsus maximus cvs.

Method for Lignin Analysis in Wood by Fluorescence Microscopy

Microscopy Research and Technique, Volume 89, Issue 4, Page 578-589, April 2026.
Autofluorescence in extractive‐free wood slides is a promising approach for investigating the relationship between fluorescence intensity and lignin content, particularly when combined with automated photomicrograph analysis using ImageJ. ABSTRACT Native Amazonian species present high anatomical variation which is reflected in their lignin content ...

Phylogenomic use of low‐copy nuclear markers from genome skimming data: An example from Melastomataceae

TAXON, Volume 75, Issue 2, April 2026.
Abstract The emergence of conflicting signals among different genomic regions, individual genes, and inference methods has been frequently reported in phylogenomic studies. Conflicts can occur from methodological error and biological processes, and disentangling the contribution of each putative source of discordance became a major challenge.

Typical Sunlit Tropical Leaves in South China Show a Consistent Isoprene Light Response

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Light strongly regulates plant isoprene emissions, yet tropical light responses vary across studies, partly due to measurement protocol differences. Using a uniform portable chamber protocol across multiple sites, seasons, species, and temperatures in South China, we find a strikingly consistent rectangular‐hyperbolic isoprene light response ...
