Variation in bark characteristics of American beech (Fagus grandifolia)
Canadian Journal of Botany, 1984Three distinct bark patterns of American beech (Fagus grandifolia Ehrh.) were exhibited by trees growing in naturally occurring forest stands in New Hampshire, U.S.A. Consistent differences in periderm anatomy were found to be associated with each particular bark pattern.

CONSTITUTION OF A WATER SOLUBLE HEMICELLULOSE FROM AMERICAN BEECHWOOD (FAGUS GRANDIFOLIA)
Canadian Journal of Chemistry, 1957Extraction of beechwood chlorite holocellulose with hot water yielded a hemicellulose in 13.4% yield (based on original extractive-free wood) containing D-xylose 72%, D-galactose 11.0%, and uronic acid 13.2%. Purification of the crude hemicellulose by complexing with Fehling's solution yielded a chemically homogeneous fraction containing D-xylose 83 ...

Mexican beech [Fagus grandifolia subsp. mexicana (Martinez) A.E.Murray] is a subspecies endemic to the Sierra Madre Oriental Mountains and considered endangered due to the low density of its populations and high degree of habitat fragmentation and environmental specificity.

The E/Z isomerization step in the biosynthesis of Z-coniferyl alcohol in Fagus grandifolia
Phytochemistry, 1987Abstract Beech bark contains significant amounts of Z-coniferyl and Z-sinapyl alcohols but not the corresponding E-isomers. There are a number of steps along the cinnamate pathway where E/Z isomerism of the cinnamyl double bond could occur. Studies of the conversion, in beech bark, of 14C-labelled E- and Z-ferulic acids, E-coniferylaldehyde and E ...

Symbiosis, 2017
In the mountains of Veracruz State (east of Mexico), the southernmost limit of Fagus in the Americas, two relict forests of F. grandifolia var. mexicana were visited between 2007 and 2009 and 2013–2014, in order to study the ectomycorrhizal (EcM) systems of these trees with Lactarius rimosellus (L. subg. Russularia) and with L. acatlanensis (L.

Biological Conservation, 2003
Fagus grandifolia var. mexicana (Mexican beech) is limited to about 10 populations (2–35 ha) in the Sierra Madre Oriental, Mexico. The objectives were to assess the current status and distribution of beech by surveying five sites. Species richness varied between three to 27 tree species in the canopy, and from nine to 29 species in the understorey ...

Asexual reproduction has been observed to be more frequently associated with marginal habitats or with higher levels of disturbance. Here we examined frequencies of clonal reproduction across populations of Fagus grandifolia with varying levels of disturbance and habitat quality. We used ISSRs to identify clonal genotypes at each of five sites.
