We define the notion of evenness and show how the Lorenz curve can be used to compare evenness between abundance vectors. It is then illustrated how the Gini evenness measure can be used as a descriptive parameter in faculty evaluation studies.

Abstract. Aim. The author has developed a criterion to test the hypothesis of uniform distribution for random variable observations in small samples. is built by using sample construct variation series ascending order and dividing each previous term this extreme term, then discarding it. resulting new processed similarly until there only one quotient left that value. Methods. paper uses methods...

Although measures of evenness of archaeological faunas are increasingly used in zooarchaeological analyses, the widely accepted hypothesis that increasing evenness should indicate increasing dietary breadth has not been tested. In this paper, I examine three factors that can contribute to changing evenness values—changing encounter rates with high-ranked prey types, changing diet breadth, and s...

Anaerobic digestion (AD) is one of the few sustainable technologies that both produce energy and treat waste streams. Driven by a complex and diverse community of microbes, AD may be affected by different factors, many of which also influence the composition and activity of the microbial community. In this study, the biodiversity of microbial populations in innovative mesophilic/thermophilic te...

Functional evenness is increasingly considered an important facet of functional diversity that sheds light on the complex relationships between community assembly and ecosystem functioning. Nonetheless, in spite of its relevant role for ecosystem functioning, only a few measures of functional evenness have been proposed. In this paper we introduce a new measure of functional evenness that refle...
