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...

The present study identifies the hot spot of Yenice and aims to determine tree diversity in Fagus-Abies, Fagus Quercus-Fagus forests, define microbial community these forests by Biolog-Ecoplate method reveal physiological profile differences at level between forests. Accordingly, soil samples were taken from predefined different communities was analyzed using Biolog EcoPlate method. In addition...

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...

Climate and atmospheric changes affect forest ecosystems worldwide, but little is known about the interactive effects of global change drivers on tree growth. In the present study, we analyzed single and combined effects of nitrogen (N) fertilization and drought events (D) on the growth of European beech (Fagus sylvatica L.) saplings in a greenhouse experiment. We quantified morphological and p...

Local and long-range transport of beech (Fagus sylvatica) pollen was analysed by using 23-year data (1983-2007) at six stations in Catalonia, Spain, and numerical simulations. Back trajectories and synoptic meteorology indicated a consistent north European provenance during beech pollen peak days. Specifically, the area from northern Italy to central Germany was the most probable source, as ind...

We examined the relationship between the community structure of wood-decaying fungi, detected by high-throughput sequencing, and the decomposition rate using 13 years of data from a forest dynamics plot. For molecular analysis and wood density measurements, drill dust samples were collected from logs and stumps of Fagus and Quercus in the plot. Regression using a negative exponential model betw...

The fossilized birth-death (FBD) model can make use of information contained in multiple fossils representing the same clade, and we here apply this model to infer divergence times in beeches (genus Fagus), using 53 fossils and nuclear sequences for all nine species. We also apply FBD dating to the fern clade Osmundaceae, with about 12 living species and 36 fossils. Fagus nuclear sequences cann...
