Sedimentary Ancient DNA Tracks Multi‐Kingdom Ecosystem Reorganizations Following Sequential Human Land Use at Crawford Lake

open access: yesMolecular Ecology, Volume 35, Issue 17, September 2026.
ABSTRACT Crawford Lake has an exceptional stratigraphic record that began recording biannual (varved) sedimentation in the lake basin ~750 years ago, preserving evidence of shifting cultural zones and agricultural practices, from Late Woodland Period Indigenous agriculturalists to the impacts of industrialization during the late 19th century.

Viral Transmission Between Heterobasidion parviporum Strains in Wood Billets and Decaying Stumps

open access: yesForest Pathology, Volume 56, Issue 4, August 2026.
ABSTRACT The combined use of Heterobasidion partitiviruses HetPV13‐an1 and HetPV15‐pa1 is considered a promising biocontrol approach against Heterobasidion root and butt rot. Both viruses mediate debilitating effects in many Heterobasidion isolates and are transmitted efficiently in laboratory conditions.

Harringtonia lauricola Spread in Sassafras Root Systems in the Absence of Its Vector, the Redbay Ambrosia Beetle (Xyleborus glabratus)

open access: yesForest Pathology, Volume 56, Issue 4, August 2026.
ABSTRACT Laurel wilt is a vascular disease caused by a non‐native pathogen (Harringtonia lauricola) and an associated beetle vector (redbay ambrosia beetle; RAB; Xyleborus glabratus) affecting several members of the Lauraceae family in North America, including the ecologically and culturally important sassafras (Sassafras albidum).

Biogeography of Bursaphelenchus Species Driven by Climate, Vectors and Hosts: Implications for Forest Pathology Under Climate Change

open access: yesForest Pathology, Volume 56, Issue 4, August 2026.
ABSTRACT Wood‐inhabiting nematodes of the genus Bursaphelenchus are a group with significant ecological and economic impacts on global forest ecosystems. This review aims to update current knowledge on their spatial distribution, host‐vector associations and the factors driving species expansion under the framework of climate change.

Antifungal actinomycetes associated with the pine bark beetle, Orthotomicus erosus, in South Africa

open access: yesSouth African Journal of Science, 2017
Actinomycete bacteria are often associated with insects that have a mutualistic association with fungi. These bacteria are believed to be important to this insect–fungus association as they produce antibiotics that exclude other saprophytic fungi from ...

Social and cultural considerations for the restoration of ‘lost’ tree species: The fall and rise of elm

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1556-1566, June 2026.
Abstract Attempts to address biodiversity loss have led to ecosystem and species restoration efforts. Tree species restoration is particularly relevant because of increasing threats from pests and pathogens. However, there are different notions of ‘loss’, as well as sociocultural considerations, including social acceptability, which are often neglected

Ophiostomatoid fungi associated with pine bark beetles and infested pines in south-eastern Australia, including Graphilbum ipis-grandicollis sp. nov.

open access: yesIMA Fungus, 2021
The ophiostomatoid fungi are an assemblage of ascomycetes which are arguably best-known for their associations with bark and ambrosia beetles (Curculonidae) and blue stain (sap stain) of many economically important tree species.
