Differences in Soil Fungal Communities between Forested Reclamation and Forestry Sites in the Alberta Oil Sands Region.

Fungi play key roles in forest soils and provide benefits to trees via mycorrhizal symbioses. After severe disturbance, forest regrowth can be impeded because of changes in fungal communities. In 2013-2014, soil fungi in forest floor and mineral soil were examined by Roche 454 pyrosequencing in undisturbed, harvested, and burned jack pine stands in a forested area near Fort Chipewyan, Alberta.

A Global Assessment of the State of Plant Health.

The Global Plant Health Assessment (GPHA) is a collective, volunteer-based effort to assemble expert opinions on plant health and disease impacts on ecosystem services based on published scientific evidence. The GPHA considers a range of forest, agricultural, and urban systems worldwide. These are referred to as (Ecoregion × Plant System), i.

Evidence of Coevolution Between Lineages and Their Corresponding Hosts, Lodgepole Pine and Jack Pine.

Variation in rate of infection and susceptibility of spp. to the fungus (syn. ), the causative agent of western gall rust, has been well documented.

Signatures of Post-Glacial Genetic Isolation and Human-Driven Migration in the Dothistroma Needle Blight Pathogen in Western Canada.

Many current tree improvement programs are incorporating assisted gene flow strategies to match reforestation efforts with future climates. This is the case for the lodgepole pine ( var. ), the most extensively planted tree in western Canada.

Ectomycorrhizal species associated with Pinus radiata in New Zealand including novel associations determined by molecular analysis.

Ectomycorrhizal (ECM) associates of the exotic plantation species Pinus radiata were investigated above and below ground over two years in the North Island of New Zealand. ECM species were identified using morphological and molecular (restriction fragment length polymorphism and DNA sequencing) analysis. Eighteen ECM species were observed fruiting above ground; 19 ECM species were identified below ground.
