We studied how the unusual capacity of mature Fagus grandifolia to form clumps of clonal stems from root sprouts can contribute to its frequent codominance with Acer saccharum in southern Quebec, Canada. In an old-growth forest, the degree of dominance by the two species shifted along topographic gradients spanning a few hundreds of meters, with Fagus ...

Suppression and Release During Canopy Recruitment in Fagus grandifolia
Bulletin of the Torrey Botanical Club, 1990CANHAM, C. D. (Institute of Ecosystem Studies, Box AB, Millbrook, NY 12545). Suppression and release during canopy recruitment in Fagus grandifolia. Bull. Torrey Bot. Club. 1 17: 17. 1990.-Stem radial growth patterns were used to reconstruct the history of suppression and release during canopy recruitment of Fagus grandifolia Ehrh.

The Fagus grandifolia-Acer saccharum-Podophyllum peltatum Association in Northeastern Ohio
Botanical Gazette, 1977Ten near-climax stands in northeastern Ohio, dominated by Fagus grandifolia and Acer saccharum, are quantitatively described. Acer seedlings are much more abundant than Fagus seedlings; the two codominants are equally well represented in the larger size classes.

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.

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.

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 ...

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 ...
