Persistently rare species experience stronger negative frequency dependence than common species: A statistical attractor that is hard to avoid. Relationship between evenness and body size in species rich assemblages. Diversity has two components: species richness, or the number of plant species in a given area, and species evenness, or how well distributed abundance or biomass is among species within a community. Species richness and evenness also had different responses to edaphic factors, with species richness being negatively correlated with phosphorus, and species evenness negatively correlated with the ratio of organic carbon to total nitrogen in soil. Mathematically it is referred as diversity index or measure of biodiversity. O que ganhamos 'confundindo' riqueza de espécies e equabilidade em um índice de diversidade?.

If thare are a lot of individuals in a few species and just a little number of individuals in the others species, the evenness will be low. But independently of […] the species evenness is who equal the relative number of species are. The probability of sustaining multiple ecosystem functions increased with species richness, but this effect was largely modulated by attributes such as species evenness, composition and spatial pattern. a different species richness) but a similare evenness ( witch is high here since the number individuals in each species are very similar ), 42738 views species richness and evenness are two independent indices [13,14,15,16]. Learn more. If we have two sites with equal species richness, yet one site is dominated by a single species whereas a second site has a more even abundance of the species, then clearly we would consider the second as more diverse.
