Journal ArticleDOI
Effect of carbon dioxide concentration on microbial respiration in soil
TL;DR: Soil microbial respiration activity was depressed with the increase of CO2 concentration in ventilated air from 0 to 1000 ppmv, and it is likely that soil respiration rate is overestimated by the alkali absorption method, because CO2 concentrations in the absorption chamber is much lower than the normal level.
Journal ArticleDOI
Frequency distribution models for spatial patterns of vegetation abundance
TL;DR: In this paper, the relationships between these distributions and their biological relevance have been clarified and a spatial heterogeneity index for each of the above four methods of measurement has been defined, and several-fitted examples of plant populations or communities were provided.
Journal ArticleDOI
Spatial pattern changes in aboveground plant biomass in a grazing pasture
TL;DR: Using gamma distribution and spatial autocorrelation, it was demonstrated that plant biomass per unit area of a pasture grazed by cattle exhibited two kinds of spatial heterogeneity: smallscale heterogeneity caused by grazing and large-scale heterogeneity due to topography, land aspect, etc as discussed by the authors.
Journal ArticleDOI
A measure for spatial heterogeneity of a grassland vegetation based on the beta-binomial distribution
TL;DR: Results indicate that (1) each species is distributed heterogeneously with respective spatial patterns, (2) the degree of heterogeneity is different from species to species, and (3) the beta-binomial distribution can be applied for grassland communities.

TL;DR: The current forest appears to be well protected based on the adult tree canopy, but regeneration of the present-day forests is unlikely because of the loss of seedlings and analysis of tree-size categories indicates a lack of small samplings near the village boundary.
