Can ectomycorrhizal colonization ofPinus resinosaroots affect their decomposition? [PDF]

open access: yesNew Phytologist, 2011
In many forest ecosystems, fine root litter comprises a large pool of organic carbon and nutrients. In temperate climates ectomycorrhizal fungi colonize the roots of many forest plant species. If ectomycorrhizal colonization influenced root decomposition, it could significantly influence carbon sequestration and nutrient cycling.

Chloroplast microsatellites: measures of genetic diversity and the effect of homoplasy [PDF]

open access: yes, 2005
Chloroplast microsatellites have been widely used in population genetic studies of conifers in recent years. However, their haplotype configurations suggest that they could have high levels of homoplasy, thus limiting the power of these molecular markers.

Regeneration patterns of key pine species in a mixed-pine forest indicate a positive effect of variable retention harvesting and an increase in recruitment with time

open access: yesForest Ecosystems, 2020
Background Many fire-dependent forests have experienced significant declines in species, structural, and functional diversity. These changes are attributed in part to traditional management approaches that were dominated by even-aged regeneration methods

Conditions conducive to an epidemic of Gremmeniella abietina, European race, in red pine plantations

open access: yesJournal of Forest Science, 2015
In North America, Gremmeniella abietina, European race (GaEU), was reported in 1975. Our objective was to follow the spread of GaEU on red pines growing on flat land and on slope. Annual height infection varied significantly on flat land, ranging from 60
