Impact of Invasive Tree Species on Natural Regeneration Species Composition, Diversity, and Density

Fire effects on composition, density and species diversity vegetation and soil seed bank (Case study: Kangavar rangelands)

Abstract Background and objectives: Fire as a frequent phenomenon in rangelands and because of its complicated and different effects on natural ecosystems, has great importance. Awareness of such fire effects on vegetation cover in point of rangeland management after fire is important and helps better Understanding and sustainable management of rangelands. Changing in plant structure and compo...

Influence of Tree Species Composition and Community Structure on Carbon Density in a Subtropical Forest

We assessed the impact of species composition and stand structure on the spatial variation of forest carbon density using data collected from a 4-ha plot in a subtropical forest in southern China. We found that 1) forest biomass carbon density significantly differed among communities, reflecting a significant effect of community structure and species composition on carbon accumulation; 2) soil ...

Strong density- and diversity-related effects help to maintain tree species diversity in a neotropical forest.

Intraspecific density-dependent effects in the Barro Colorado Island (Panama) study area are far stronger, and involve far more species, than previously had been suspected. Significant effects on recruitment, many extremely strong, are seen for 67 out of the 84 most common species in the plot, including the 10 most common. Significant effects on the intrinsic rate of increase are seen in 54 of ...
