Dual Isotope Analysis Reveals Phylogenetic Patterns and Novel Insights Into Methoxy Group Synthesis of Structural Biomolecules in Leaf and Woody Plant Tissues

Plant, Cell &Environment, Volume 48, Issue 12, Page 8483-8501, December 2025.
ABSTRACT Stable carbon and hydrogen isotopes of wood methoxy groups (δ2Hmeth, δ13Cmeth), mainly sourced by structural biomolecules like lignin and pectin, provide important insights into climatic, hydrological and physiological conditions. This study systematically investigated species‐specific δ2Hmeth and δ13Cmeth variations in leaves and woody twigs ...

Contrasting Phylogenetic Signals in Flowering and Fruiting Phenology at Species and Assemblage Scales in a Climbing Plant Community

Journal of Vegetation Science, Volume 36, Issue 6, November/December 2025.
This study examined the phylogenetic conservatism of flowering and fruiting in 78 climbing plant species relative to environmental gradients in a South Brazilian forest. Although species‐level analysis found a weak phylogenetic signal, a strong influence was detected at the assemblage scale, revealing that evolutionary history mediates the phenology ...

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration

Plant-Environment Interactions, Volume 6, Issue 5, October 2025.
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

Herbivory Dominates the Spring Diet of American Black Bears (Ursus americanus) in a Wood Bison (Bison bison athabascae) Neonatal Range, Suggesting Minimal Bison Consumption

Ecology and Evolution, Volume 15, Issue 9, September 2025.
In this study, we used scat analysis and DNA metabarcoding to analyze the spring diet of black bears in the neonatal range of a small, threatened wood bison herd in northeast Alberta to assess predation risk of neonate bison. Our results suggest that consumption rates of bison are low and that predation risk to neonate wood bison, during the RLBH's ...
