摘要

In 生態學, there have been attempts to establish links between the relative 物種 abundance (RSA), the fraction of 物種 in a community with a given abundance, and a power-law form of the 物種 area relationship (SAR), the dependence of 物種 richness on sampling area. However the SAR and other patterns in 生態學 often do not exhibit power-law behavior over an appreciable range of scales. This raises the question whether a 縮放律 framework can be applied when the system under analysis does not exhibit power-law behavior. Here, we derive a general finite-size 縮放律 framework applicable to such systems that can be used to identify incipient critical behavior and links the scale dependence of the RSA and the SAR. We confirm the generality of our theory by using data from a serpentine grassland plot, which exhibits
