Correct Identity of the Oak Twig Pruner (Coleoptera: Cerambycidae) [PDF]

open access: yes, 2017
(excerpt) The oak twig pruner is a cerambycid of minor economic importance which is generally common through most of eastern North America. The adult beetles oviposit on living twigs of oak and other hardwoods, and the larvae bore within the twig ...

Island influences on plant functional traits and trait–trait associations across species‐ and community‐scales

open access: yesNew Phytologist, Volume 250, Issue 4, Page 2176-2189, May 2026.
Summary The island rule predicts gigantism or dwarfism in body size of island species relative to their mainland counterparts. However, whether other functional traits shift and whether trait–trait associations on islands differ between species and community levels remains unclear. We measured 13 carbon‐ and water‐related functional traits in 37 shared

Fungal Pathogen Activity and Stress‐Dependent Responses of Grapevine Wood to Esca and Drought

open access: yesPhysiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Biotic and abiotic stresses alter the physiology of perennial plants, with consequences for fungal endophytes and disease expression. In grapevine, drought inhibits esca disease expression, but the underlying molecular interactions between the plant and fungi are unknown. We combined wood metatranscriptomics, metabolomics, and metabarcoding to
