The measurement of the size evennessART-2016-97562A method for the measurement of the size diversity based on the classical Shannon-Wiener expression was proposed as a proxy of the shape of the size distribution. The summatory of probabilities of a discrete variable (such as species relative abundances) in the original Shannon-Wiener expression was substituted by an integral of the probability density function of a continuous variable (such as body size). Here, we propose an update of this method by including the measurement of the size e-evenness, just dividing the exponential of the size diversity by its possible maximum for a given size range. Assuming a domain of the size range of (0, 8), for a given logarithmic mean ( mln) and a logarithmic standard deviation (sln), the distribution with the highest diversity is the Log-Normal. The size e-evenness ranges between 0 and 1 because of the division by the maximum exponential diversity. Size e-evenness is useful to discriminate whether variations in size diversity are due to changes in the shape of the size distribution or caused by differences in size dispersion.2016http://zaguan.unizar.es/record/5847210.1002/lom3.10099http://zaguan.unizar.es/record/58472oai:zaguan.unizar.es:58472LIMNOLOGY AND OCEANOGRAPHY-METHODS 14, 6 (2016), 408-413byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
