In this research, biodiversity was investigated in the species diversity level. The objective of this research was to study of Norway Maple (Acer platanoides L.) dispersion and biodiversity of associated woody species in the Shafaroud forests, Gilan (IRAN). In this regard, a 0.5 ha lozenge sample plot was selected with considering presence of Norway Maple in each site. In each plot, geographic ...

Studies of tree regeneration following forest fires along the Colorado Front Range offer valuable insights into how climate change could be influencing conifer seedling establishment statewide. While the relatively hotter and drier conditions observed along the Front Range may not be enough to lethally damage mature trees, there is a strong potential that these novel conditions could prevent th...

Effects of prescribed fires on the 1-year establishment of white oak seedlings were investigated on the Clemson Experimental Forest, South Carolina, USA. Three stands, each consisting of a burn and a control treatment of about 1 ha in size, were examined in the study. On each burn and control treatment, six to eight dominant white oak trees were randomly selected along the slope and four 2-m ra...

1 Tree diversity in forests may be maintained by variability in seedling recruitment. Although forest ecologists have emphasized the importance of canopy gaps in generating spatial variability that might promote tree regeneration, the effects of canopy gaps on seedling recruitment may be offset by dense forest understories. 2 Large annual fluctuations in recruitment processes, coupled with the ...

Tree recruitment is a spatially structured process that may undergo change over time because of variation in postdispersal processes. We examined seed pilferage, seed germination, and seedling survival in whitebark pine to determine whether 1) microsite type alters the initial spatial pattern of seed caches, 2) higher abiotic stress (i.e. higher elevations) exacerbates spatial distribution chan...
