Patterns and drivers of biotic disturbance hotspots in western United States coniferous forests

open access: yesEcography, Volume 2025, Issue 9, September 2025.
Globally, forest disturbances caused by herbivorous insects and plant pathogens (i.e. biotic disturbances) have increased since the 1990s, a trend linked in part to climate warming. With increases in biotic disturbance activity, an emerging ecological phenomenon has been documented: biotic disturbance ‘hotspots', or areas where two or more biotic ...

Mobile genetic elements explain size variation in the mitochondrial genomes of four closely-related Armillaria species

open access: yesBMC Genomics, 2019
Background Species in the genus Armillaria (fungi, basidiomycota) are well-known as saprophytes and pathogens on plants. Many of them cause white-rot root disease in diverse woody plants worldwide.

Biological Flora of Britain and Ireland: Cytisus scoparius*

open access: yesJournal of Ecology, Volume 113, Issue 7, Page 1877-1933, July 2025.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

Geographical Gradient of Fungal Decay Type in Norway Spruce Logs in Europe and Its Impact on Seedling Establishment

open access: yesJournal of Biogeography, Volume 52, Issue 7, July 2025.
ABSTRACT Aim Norway spruce (Picea abies) is a dominant tree species across Eurasia, and is known to regenerate on decaying logs. Understanding its regeneration dynamics is crucial for predicting forest sustainability under climate change. The decay type of the logs, indicative of fungal decay capabilities of lignin and holocellulose and traditionally ...

Field Testing Peach Rootstocks for Resistance to Armillaria Root Rot [PDF]

open access: yesHortScience, 2001
Armillaria root rot is the second leading cause of peach tree mortality (after peach tree short life) in the southeastern United States. Currently, there are no commercially available rootstocks for peach with proven resistance to this pathogen in the United States.

Ilyonectria Species Associated With Tree Decline in Pinus taeda in Brazil

open access: yesJournal of Phytopathology, Volume 173, Issue 4, July/August 2025.
ABSTRACT Characteristic symptoms of decline were observed in 10‐year‐old Pinus taeda (loblolly pine) trees in plantations located in the state of Santa Catarina, in the humid subtropical south of Brazil. Aboveground, we observed needle chlorosis, followed by drying and shortening of needles, formation of tufts on branch tips, and death of the canopy at
