Figure 6
Five patterns of density-mass relationship estimated in a single metacommu-
nity. (A) Each point represents a different taxa relating the total number of individuals
recorded in the metacommunity and its mean body size. (B) The same pattern as in (A)
but only considering a local community. (C) Inverse cumulative distribution for all the
individuals in the metacommunity. The solid lines were obtained by fitting a segmented
regression. The inset table shows the AIC values for alternative models highlighting the
model with the lowest value. (D) Reproduction of the analysis in (C) but considering the
mean body size of all the species. (E) Cross-community or self-thinning scaling in
community density with the mean size of all the individuals.
