First Report of <i>Ophiostoma clavatum</i> and <i>Fusarium verticillioides</i> Associated With <i>Ips acuminatus</i>-Infested Scots Pine in Western Ukraine. [PDF]

Plant Environ Interact
This study provides the first record of Ophiostoma clavatum associated with Ips acuminatus in Ukraine, and the first evidence of Fusarium verticillioides coexisting with ophiostomatoid fungi in infested Scots pines. This fungal association may contribute to the decline of Scots pine stands.

Forest health, heart rot disease, and their impact on the source of carbon-based greenhouse gas fluxes. [PDF]

New Phytol
Summary Forest health is critical for sustaining ecosystem services like carbon sequestration. Heart rot, a widespread disease in upland northern hardwood forests, may affect greenhouse gas (CO2 and CH4) fluxes, but its impacts remain poorly measured. Using non‐destructive tomography and direct gas flux measurements, we quantified the effects of heart ...

Extractives elucidation of Taiwania cryptomerioides sapwood [PDF]

Journal of Wood Science, 2021
AbstractTaiwania (Taiwania cryptomerioides Hayata) has long been regarded as a living fossil from the Tertiary period of Mesozoic Era for its distinguished yellowish-red color with purplish-pink streaks presented in its heartwood. With this elegant appearance that matches the color “red” for good fortune in the Taiwanese culture, Taiwania is supposed ...

Beyond species means - the intraspecific contribution to global wood density variation. [PDF]

New Phytol
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Penetration and effectiveness of micronized copper in refractory wood species [PDF]

, 2016
The North American wood decking market mostly relies on easily treatable Southern yellow pine (SYP), which is being impregnated with micronized copper (MC) wood preservatives since 2006. These formulations are composed of copper (Cu) carbonate particles (
