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...

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.

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...

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...

In nature, plant biomass is not evenly distributed across species, and naturally uncommon species may differ from common species in the probability of loss from the community. Understanding relationships between evenness and productivity is therefore critical to understanding changes in ecosystem functioning as species are lost from communities. We examined data from a large multi-site grasslan...

Consumer and resource control of diversity in plant communities have long been treated as alternative hypotheses. However, experimental and theoretical evidence suggests that herbivores and nutrient resources interactively regulate the number and relative abundance of coexisting plant species. Experiments have yielded divergent and often contradictory responses within and among ecosystems, and ...

The design of road surfaces involves application a sophisticated algorithm system based on mathematical calculations and engineering solutions, with the calculation evaluation criteria. It is precisely observance standardized requirements in terms criteria that makes it possible to consider pavement as reliable, safe convenient for traffic during specified service life. When calculating strengt...
