Journal ArticleDOI
Measuring beta diversity for presence–absence data
TL;DR: In this article, four groups of measures are distinguished, with a fundamental distinction arising between broad sense measures incorporating differences in composition attributable to species richness gradients, and narrow sense measures that focus on compositional differences independent of such gradients.
Journal ArticleDOI
The geographical structure of British bird distributions: diversity, spatial turnover and scale
TL;DR: In this article, the authors investigated the relationship between species richness (alpha diversity) and spatial turnover of species (beta diversity) in British avifauna and found that high richness locations have fewer species in common with neighbouring areas than low richness locations.
Journal ArticleDOI
Contribution of rarity and commonness to patterns of species richness
TL;DR: It is shown here that commoner species are most responsible for richness patterns, suggesting that a broad understanding of what determines the majority of spatial variation in biodiversity may be had by considering only a minority of species.
Journal ArticleDOI
Are there latitudinal gradients in species turnover
TL;DR: In this article, the authors examine the effect on the observed relationship between spatial turnover and latitude of both the measure of beta diversity used and the method of analysis and conclude that species richness declines at higher latitudes and there is also some evidence that species turnover is greater nearer the equator.
Journal ArticleDOI
Assessing completeness of biodiversity databases at different spatial scales
TL;DR: Sobero'n et al. as discussed by the authors presented the results of the CONABIO-NACION project in Mexico, where the authors proposed a method for the identification of the most important species in the world.
