Functional Ecology, Volume 40, Issue 5, Page 1151-1164, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

Agricultural and Forest Entomology, Volume 28, Issue 2, Page 149-159, May 2026.Acalolepta aesthetica is a non‐native cerambycid established on the Island of Hawaiʻi. We show its preferred hosts are woody species that are highly valued for agricultural, horticultural and cultural uses. We used a resource selection function to estimate host preferences and found that kukui (Aleurites moluccanus), the state tree, was preferred ...

Ecohydrology, Volume 19, Issue 3, April/May 2026.ABSTRACT Understanding the oxygen and hydrogen isotopic composition (δ18O and δ2H values, respectively) of plant source water is fundamental for tracing water uptake in ecohydrological studies. However, discrepancies between cryogenic vacuum distillation (CVD)‐extracted soil and xylem water and known plant source water δ18O and δ2H values continue to ...

Ecohydrology, Volume 19, Issue 3, April/May 2026.ABSTRACT Emissions from trees are an important component of the global methane (CH4) cycle, but their spatial origins (soil vs. in‐stem), transport pathways and environmental influences are not well constrained. To address these issues, this field study characterized spatial and temporal variability in stem emissions of biologically inert radon (222Rn),

THE HEARTWOOD EXTRACTIVES OF PINUS BANKSIANA LAMB
Canadian Journal of Chemistry, 1963 The heartwood of jack pine was analyzed by various chromatographic techniques and countercurrent distribution. The major components were found to be isopimaric, abietic, dehydroabietic, and neoabietic acids, as well as glycerides of oleic, linoleic, and linolenic acids.
