A new species and a new record of Laccaria (Fungi, Basidiomycota) found in a relict forest of the endangered Fagus grandifolia var. mexicana [PDF]

MycoKeys, 2017
Two species of Laccaria discovered in relicts of Fagus grandifolia var. mexicana forests in eastern Mexico are described based on the macro- and micromorphological features, and their identity supported by molecular analysis of the internal transcribed ...

Fagus grandifolia: American Beech

EDIS, 2014
This massive tree will slowly reach a height and spread of 50 or more feet. Forest grown trees reach up to 120 feet. The tree is naturally low-branched with attractive glossy green leaves providing deep, inviting shade.

Comparisons of protein profiles of beech bark disease resistant and susceptible American beech (Fagus grandifolia). [PDF]

Proteome Sci, 2013
Abstract Background Beech bark disease is an insect-fungus complex that damages and often kills American beech trees and has major ecological and economic impacts on forests of the northeastern United States and southeastern Canadian forests. The disease begins when exotic beech scale insects feed on the bark of trees,

Leaf litter and fine roots have distinct effects on particulate and mineral-associated soil organic matter in a tree common garden. [PDF]

New Phytol
Summary Soil organic matter (SOM) is primarily derived from leaf and root inputs, but the relative contributions of each are difficult to study without the use of isotopic tracers. Furthermore, associations between trees and mycorrhizal fungi can influence the production and persistence of SOM.

Deciphering the vectors: Unveiling the local dispersal of Litylenchus crenatae ssp. mccannii in the American beech (Fagus grandifolia) forest ecosystem. [PDF]

PLoS ONE
Beech leaf disease (BLD), caused by the Litylenchus crenatae ssp. mccannii (Lcm) nematode, is an emerging threat to beech trees. This disease is characterized by distinct leaf symptoms, including leaf interveinal banding and thickened leaf texture, which

Spring ephemeral Erythronium umbilicatum may not be vulnerable to phenological mismatch with overstory trees. [PDF]

Am J Bot
Abstract Premise The defining life history strategy of spring ephemeral wildflowers is their avoidance of shading by trees during the brief, high‐light period before canopy leaf out. Studies suggest that spring ephemerals will experience increased light competition because canopy leaf out is more sensitive to warming than is the phenology of spring ...

Prioritizing Conservation of Trailing-Edge Populations for Future Climate-Resilient Forests. [PDF]

Glob Chang Biol
Climate change threatens warm‐ and dry‐edge tree populations that may harbor adaptive genetic variation important for future forest resilience. We identified trailing‐edge populations for frequent and widespread North American tree species using climate and forest inventory data, then prioritized conservation actions based on projected forest habitat ...
