Multiple and interacting disturbances lead to Fagus grandifolia dominance in coastal New England
BUSBY, P. E., G. MOTZKIN, AND D. R. FOSTER (Harvard Forest, Harvard University, Petersham, MA 01366). Multiple and interacting disturbances lead to Fagus grandifolia dominance in coastal New England. J. Torrey Bot. Soc. 135: 000–000. 2008.—Recent studies have emphasized the importance of multiple and interacting disturbances in controlling plant community dynamics. However, detailed information...
متن کاملHabitat differences influence genetic impacts of human land use on the American beech (Fagus grandifolia).
Natural reforestation after regional forest clearance is a globally common land-use sequence. The genetic recovery of tree populations in these recolonized forests may depend on the biogeographic setting of the landscape, for instance whether they are in the core or in the marginal part of the species' range. Using data from 501 individuals genotyped across 7 microsatellites, we investigated wh...
متن کاملDo interspecific differences in sapling growth traits contribute to the co-dominance of Acer saccharum and Fagus grandifolia?
BACKGROUND AND AIMS Acer saccharum and Fagus grandifolia are among the most dominant late-successional tree species in North America. The influence of sapling growth responses to canopy gaps on the co-dominance of the two species in an old-growth forest in southern Quebec, Canada was examined. Two predictions were evaluated: (a) F. grandifolia is more shade tolerant than A. saccharum due to gre...
متن کاملMature beech trees (Fagus grandifolia; Fagaceae) are persistently clonal in coves and beech gaps in the Great Smoky Mountains.
PREMISE OF THE STUDY Angiosperms frequently have mixed sexual and asexual reproductive strategies, which can have significant consequences for population and community structure. Many tree species respond to disturbance by vegetative sprouting over sexual reproduction, but the ability to do so varies within and among species and is poorly studied. We tested the hypothesis that root sprouting in...
متن کاملDemographic genetics of the American beech, Fagus grandifolia. II. Genet substructure of populations for the Blue Ridge, Piedmont and the Great Smoky Mountains
Populations of American beech in Virginia and the Great Smoky Mountain National Park in Tennessee and North Carolina were investigated for demographic genetic substructurings. Two Virginia populations, one on the Blue Ridge (WG1) and the other on the Piedmont (WG2) occur over an elevational gradient of several hundreds meters. One of the Great Smoky Mountain populations (GS1) was in a ‘beech ga...
