Climate Change Projected to Double the Richness and Abundance of Soilborne Phytopathogenic Fungi in Southern Maritime Antarctica

Global Change Biology, Volume 32, Issue 5, May 2026.
We sequenced fungal DNA in barren soils sampled from 12 sites along a 1900‐km transect through sub‐ and Maritime Antarctica and Patagonia. Using LASSO regression, we found air temperature ‐ and notably mean annual air temperature (BIO1) ‐ to be a highly significant predictor for the richness and relative abundance of soilborne plant pathogens.

Nutrient addition, but not vertebrate predator exclusion, shapes arthropod communities and herbivory in a temperate forest

Ecological Entomology, Volume 51, Issue 2, Page 303-321, April 2026.
We experimentally manipulated top‐down (predator exclusion) and bottom‐up (fertilisation) forces in a temperate forest understory to test effects on arthropod densities, body sizes and herbivory. Predator exclusion had no detectable effect on arthropod density, herbivory damage or body size, whereas fertilisation increased herbivory damage and ...

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

Forest 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 ...

Occurrence of oidium in cowpea influenced by cropping system and planting season

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract Cowpea (Vigna unguiculata (L.) Walp.) is a crop of major importance in semiarid regions, where powdery mildew can significantly reduce productivity. This study evaluated powdery mildew severity in four cowpea cultivars grown under monocropping and intercropping with two biomass sorghum (Sorghum bicolor (L.) Moench) across two planting seasons (
