community
That such a factorization is possible is well-known to algebraists (and expressed by the formulaSL(n;R[z, z-1])=E(n;R[z, z-1])); it is also used in linear systems theory in the electrical engineering community.
      
Following the methodology of community ecology, the total root mass of a phytocommunity is measured as cubic volume.
      
The RENIs of three community types (Picea crassifolia + Hippophae rhamnoides ssp.
      
The standing crop of N in the plant community was 1,025.28 kg/hm2, accumulation in the litter layer was 224.88 kg/hm2, and reserve in the soil was 55,151 kg/hm2.
      
Compared with other forest types, cycling rate of N in the community was lower than in deciduous broad-leaved forests, rain forests, and mangroves, and was moderate in evergreen broad-leaved forests.
      
According to the characteristics of the biocycle of phosphorous, it was concluded that N availability in the soil of this forest was not lower, and phosphorous not N was the limiting factor in the growth of plants in this community.
      
NFPPG took both the classification management and the protection of forest community types into account, as well as the ecological environment.
      
In terms of Shannon-Wiener index, evenness index, and abundance index, the biodiversity in gap community were higher than those under forest canopy in regeneration layer.
      
Based on the data collected from 27 plots of the Pinus armandii community in Qinling Mountains, we studied the spatial distribution pattern, scale, and gap characteristics of the P.
      
The Shannon-Wiener index, evenness index, and abundance index in gap were higher than those under canopy in the seedling layer, while the community dominance in the seedling layer increased in closed canopy.
      
Interspecific relationships in the forest community dominated by Pinus kwangtungensis, an endangered species endemic to China
      
The results from CCA and cluster analysis indicated that environmental factors influenced the distribution and ecological characteristics of the plant species in the forest community dominated by P.
      
The genetic similarity between coniferous and broad-leaved mixed forest community and evergreen broad-leaved forest community was the highest, while that between evergreen broad-leaved forest community and coniferous forest community was the lowest.
      
Studies on species diversity of Larix chinensis community ecotone
      
It is apparent that the edge effect of community was affected by soil and terrain, but not by microclimate.
      
acutesrata community on Mountain Xiaolong in Gansu Province, China
      
acutesrata community on Mountain Xiaolong in Gansu Province, China.
      
acutesrata community was 183 660 kg/ha, in which the slow growth group accounted for 64.89% of the total biomass.
      
The total biomass accumulated with the development of the community.
      
The total biomass and the biomass of the organs were highest in the mature community and became stable as the community developed.
