Effects of dispersal, shrubs, and density- dependent mortality on seed and seedling distributions in temperate forests
Processes limiting recruitment of trees may have large impacts on forest dynamics. In this paper, we determined the effects of dispersal, shrubs (Rhododendron maximum), and density-dependent mortality on seed and seedling distributions of Southern Appalachian trees. We quantified the spatial distribution of seed rain, seed bank densities, first-year seedlings, and older than first-year seedling...

متن کاملDoes relatedness matter? Phylogenetic density-dependent survival of seedlings in a tropical forest.
A complex set of interactions among neighbors influences plant performance and community structure. Understanding their joint operation requires extensive information on species characteristics and individual performance. We evaluated first-year survival of 35719 tropical forest seedlings of 222 species and 15 annual cohorts relative to the density of conspecific and heterospecific neighbors an...
متن کاملDo fungal pathogens drive density-dependent mortality in established seedlings of two dominant African rain-forest trees?
Where one or a few tree species reach local high abundance, different ecological factors may variously facilitate or hinder their regeneration. Plant pathogens are thought to be one of those possible agents which drive intraspecific density-dependent mortality of tree seedlings in tropical forests. Experimental evidence for this is scarce, however. In an African rain forest at Korup, we manipul...
متن کاملSeed dispersal and density-dependent seed and seedling survival in Trichilia tuberculata and Miconia argentea
We investigated seed dispersal and density-dependence of seed, seedling and sapling survival in two BCI tree species of contrasting life history strategies, using data from seed traps, soil seed samples, seedling plots within the forest dynamics plot, and the plot census data themselves. Seed dispersal distances and seed production per unit basal area were significantly higher in Miconia argent...
