Herbarium Specimens Provide Evidence for the Early Introduction of Erysiphe quercicola Into the United States and Document New Hosts

open access: yesForest Pathology, Volume 56, Issue 2, April 2026.
ABSTRACT The powdery mildew fungus Erysiphe quercicola (Erysiphaceae) has a complex taxonomic history that has long complicated assessments of its geographic distribution and host associations. Although knowledge of the global host range of this species has expanded substantially over the past two decades, sequencing‐confirmed records from North ...

Genetic Diversity Impacts Climate‐Induced Species Range Shifts

open access: yesEcology Letters, Volume 29, Issue 4, April 2026.
Genetic diversity may buffer species against climate‐driven range contractions and facilitate expansions, but its role at a global scale remains unclear. Using 4673 range shift estimates for 1888 species, we show that higher genetic diversity reduces trailing edge contractions under rapid warming and accelerates leading edge expansions under moderate ...

Land Use Influences on Freshwater Biodiversity

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 4, April 2026.
ABSTRACT Aim Land‐use change is a major driver of biodiversity loss, but most generalisations about its effects come from terrestrial ecosystems. Given the fundamental differences in spatial structure and community assembly processes between terrestrial and freshwater ecosystems, biodiversity responses to land‐use change may diverge.

Analysis of Regulatory Inhalation Unit Risk Estimates for Cobalt: Comparison to Epidemiological Data

open access: yesRisk Analysis, Volume 46, Issue 4, April 2026.
ABSTRACT Several cancer potency estimates have been proposed by regulatory agencies to characterize the dose response of cobalt and/or cobalt compounds. The objective of this research is to investigate whether these proposed cancer potency estimates for certain cobalt substances align with the available epidemiology literature.

Subcritical Cracking Associated With Subgrain Rotation Recrystallisation in Quartz Inferred From Cathodoluminescence Study

open access: yesTerra Nova, Volume 38, Issue 2, Page 141-147, April 2026.
ABSTRACT We employed cathodoluminescence (CL) to study deformed quartz phenocrysts from the Cretaceous granite porphyry in SW Japan and observed fracture‐like planar structures appearing as CL‐dark bands. These CL‐dark bands were aligned with low‐angle grain boundaries formed by subgrain rotation recrystallisation.
