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.

An alternative approach to allometric above‐ground woody biomass models using symbolic regression and terrestrial laser scanning

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
We provide a new workflow to construct allometric models from TLS‐derived tree structural data, which serves as a template to improve the estimation of tree volume, AGB or carbon stocks. Following the workflow, we suggest pathways to improve model performance, present three ready‐to‐use allometric models for Acer pseudoplatanus in southern Great ...

Simulating past and future refugia for temperate trees in northern Italy

open access: yesEcography, Volume 2026, Issue 7, July 2026.
During the Quaternary, trees responded to the climatic changes of glacial–interglacial cycles with large‐scale range shifts. Over cold glacials, temperate tree species contracted their ranges and survived in areas known as refugia. Several studies point to the Euganean Hills (Colli Euganei), in Veneto, northern Italy, as one of the northernmost ...
