Effects of tree diversity and mycorrhizal type on the spatio‐temporal variability of leaf litter production and quality in temperate forests

open access: yesJournal of Ecology, Volume 114, Issue 4, April 2026.
This study tested whether combining high tree species richness with mixed mycorrhizal types (arbuscular mycorrhizal [AM] and ectomycorrhizal [EM] fungi) enhances productivity in forest ecosystems. Results did not support this: neither litter production nor nutrient traits benefited from mycorrhizal mixing.

Adapting Species Risk Assessments to a Changing Climate: The Underestimated Vulnerability of Foundational Trees

open access: yesGlobal Change Biology, Volume 32, Issue 4, April 2026.
Climate change is one of the top threats to biodiversity. However, many species risk assessment frameworks, including the globally authoritative International Union for Conservation of Nature Red List, do not consistently and comprehensively incorporate loss of climatically suitable habitat into listing or threat categorization decisions.

Forest Structure and Maintenance Mechanisms of Montane Riparian Forests Under Extreme Snowfall in the Cool‐Temperate Zone of Western Fukushima, Japan

open access: yesPlant Species Biology, Volume 41, Issue 2, March 2026.
In extreme heavy snowfall environments (maximum snow depth of 5 m), dominant species such as Pterocarya rhoifolia and Aesculus turbinata exhibited different survival strategies—sprouting, dwarfing, and layering—compared to their tall forms in heavy snowfall areas (maximum 2 m).

Improved Longan Genome Assembly Reveals Insights Into Flowering Mechanisms

open access: yesPlant Biotechnology Journal, Volume 24, Issue 3, Page 1678-1696, March 2026.
ABSTRACT Longan is an exotic tropical fruit crop and exhibits off‐season flowering induced by potassium chlorate (KClO3), though the molecular mechanisms remain unclear. We assembled a high‐quality, 441.5 Mb genome of variety ‘Shixia’, with a contig N50 at 28.1 Mb, 29, 325 protein‐coding genes, 26 telomeres and 15 centromeres.

A graduated nativeness definition for overcoming dilemmas and difficulties of vascular plant species

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Nativeness is a concept central to biodiversity conservation and invasion biology, but there are several problems related to a classic binary nativeness definition. Dilemmas arise from the dynamic nature of species' distribution ranges on longer time scales, and difficulties arise in the application to smaller regions defined by arbitrary borders, and ...
