Molecular tools can rapidly identify and track Fusarioid pathogens to mitigate novel pathogen introductions by informing both pathogen composition and pathogenicity of different Fusarium spp. Understanding the community structure and population genetics of Fusarium spp. is a prerequisite for developing robust primers to detect pathogenic species. Accessory chromosomes have been identified in fungi that house virulence genes that can be horizontally transferred among species...AuthorsJohn T.

- Armillaria root disease (ARD) is among the largest causes of mortality and lost productivity in forests of the western USA (Lockman and Kearns 2016, Kim et al. 2022). In some forest areas of western North America, growth/volume losses between 16-55% have been attributed to ARD (Filip and Goheen 1984; Cruickshank 2011). Damage from ARD is expected to increase under climate change and extreme weather events (e.g., drought, temperature), because host tree stress can predispose trees to ARD (Klopfenstein et al 2009; Kim et al. 2021; Murray and Leslie 2021). Furthermore, ARD may predispose...AuthorsJohn W. Hanna, Mee-Sook Kim, Patrick I. Bennett, Ashley E. Hawkins, Chris A. Lee, Kim Corella, Charles W. Barnes, Wallis L.

- Relatively little is known about the ecology and distribution of Armillaria altimontana compared with some other Armillaria species in North America. After first being recognized as an unnamed North American Biological Species X based on mating tests (Anderson and Ullrich 1979), A. altimontana was subsequently formally described by Brazee et al. (2012). While A. altimontana is occasionally found as a pathogen causing Armillaria root disease, it is often only found in a saprophytic state as rhizomorphs on diverse coniferous and broad-leaved trees and shrubs. A previous study suggests that...AuthorsJohn W. Hanna, Mee-Sook Kim, Patrick I. Bennett, Geral McDonald, Ned B. KlopfensteinSourceIn: Brooks, Rachel K., compiler.

- Black stain root disease (BSRD), a vascular wilt disease of conifers caused by a native insect-vectored fungus, is among the top five most damaging root diseases in forests of the western United States (Hadfield et al., 1986). Previously, the fungi that cause BSRD were described as three varieties of Leptographium wageneri - L. wageneri var. wageneri, L. wageneri var. ponderosum, and L. wageneri var. pseudotsugae (Kendrick) Wingfield (Kendrick, 1962; Wingfield, 1985). These L. wageneri varieties were differentiated based on morphology, physiology (Harrington and Cobb, 1987), and ecology...AuthorsThomas C. Harrington, David C. Shaw, Jane E. Stewart, Patrick I.

- Cronartium ribicola is an invasive forest pathogen that causes white pine blister rust, which threatens the health and productivity of five-needled white pines including iconic species, such as western white pine (WWP; Pinus monticola) and whitebark pine (WBP; P. albicaulis) in western North America. The pathogen has invaded most of the natural ranges of WWP and WBP and has dramatically altered forest composition and structure across the landscape (Neuenschwander et al. 1999). In recent decades, efforts to increase resilience of forest landscapes have led to a renewed interest in restoring...AuthorsPatrick I. Bennett, Jason R.

- The virulent root disease pathogen Armillaria solidipes causes a white rot of conifers in the western USA, leading to tree mortality and altering forest structure. Few effective methods are available for managing Armillaria root disease on the landscape scale. While previous studies have indicated the potential for the soil microbial community, including biological control agents, to influence the disease activity of A. solidipes, these communities will likely be impacted by increasingly common wildfires in these forest ecosystems. This research aims to determine the potential influence of...AuthorsAda Fitz Axen, Ned B. Klopfenstein, Mee-Sook Kim, John W. Hanna, Patrick I. Bennett, Sara Ashiglar, Jane E.

- Recent advances in data science and urban environmental health research utilise large-scale databases (100s–1000s of cities) to explore the complex interplay of urban characteristics such as city form and size, climate, mobility, exposure, and environmental health impacts. Cities are still hotspots of air pollution and noise, suffer urban heat island effects and lack of green space, which leads to disease and mortality burdens preventable with better knowledge. Better understanding through harmonising and analysing data in large numbers of cities is essential to identifying the most...AuthorsGeorgia M.C.

- To facilitate effective management strategies for hardwood forests, it is essential to understand both the economic and ecological objectives associated with forest or orchard development, especially for timber and nut production. Most of the forested land within the Central Hardwood Forest Region (CHFR) is privately owned or managed by governmental agencies. As such, private landowners, or persons in management positions within governmental entities are charged with developing the land to best suit the economic/wildlife interests of the property owner. If such management options include...AuthorsShaneka Lawson, Niall Lue Sue, Mark CogeshallKeywordsSourceThe NutshellYear2024
- Eastern oak (Quercus spp.) forests in the United States have experienced significant ecological changes over the past century due to fire exclusion and land-use changes. Historically, anthropogenic (human-ignited) fire regimes maintained oak dominance by reducing mesophytic (shade-tolerant, fire-intolerant) competitors, such as red maple (Acer rubrum) and American beech (Fagus grandifolia). With the loss of fire across the landscape, these species have become more abundant, suppressed oak regeneration, and altered forest structure in a process known as mesophication.
