Assessment of beech scale resistance in full- and half-sibling American beech
militaris was sampled on an American beech
sapling in the understorey on 3 July 2007, the acrocerid larva had pupated a week later, and the adult fly emerged approximately 2 wk later.
White pine (Pinus strobus) and American beech
(Fagus grandifolia) sapwood blocks in dimensions of 14 by 14 by 14 mm were weighed after having been oven dried at 105[degrees]C.
In addition to its shade tolerance and longevity, American beech
may also be resistant to exogenous damage caused by tropical storms (Batista et al.
However, the current disturbance regime of primarily large, wind created gaps seems to favor the regeneration of sugar maple and American beech
over oak species.

Dominant species included sugar maple (Acer saccharum), eastern hemlock (Tsuga canadensis), American beech
(Fagus grandifolia), mountain silverbell (Halesia carolina), white basswood (Tilia heterophylla), yellow buckeye (Aesculus octandra), and yellow birch (Betula allegheniensis).
The species included sugar maple, American beech
, white ash, yellow birch, white pine, and eastern hemlock, but all species were not studied at all three sites.

tree trunks is contrasted by the bleached wheat of their marcescent winter leaves all along the Rock Creek Parkway, where they are admired by D.
At lower elevations dominant tree species included black cherry (Primus serotina), sugar maple (Acer saccharum), red maple (Acer rubrum), yellow birch (Betula alleghaniensis), American beech
(Fagus grandifolia), and northern red oak (Quercus rubra).
(Fagus grandifolia Ehrhart) in North America are in a highly degraded state in much of the northeastern United States and eastern Canada due to beech bark disease, which is caused by an invasive scale, Cryptococcus fagisuga Lindinger (Hemiptera: Eriococcidae), and 2 fungal plant pathogens, i.
