Abstract
A new technique for assessing functional diversity is proposed, which is essentially a way to calculate Rao’s quadratic entropy. In contrast to the original method of calculating entropy, the new method takes into account intraspecific variability and allows us to evaluate other useful aspects of functional diversity, such as functional richness, functional evenness, the uniqueness of each species, and the contributions to functional diversity of intraspecific variability of each species and each trait separately. However, due to the peculiarities of the calculation, the proposed technique can only be applicable for an absolute count of all organisms within the “island” community or when collecting material based on a fixed sampling effort. The article provides an example of the application of the proposed technique to real rodent trapping data.
