Using Species Proportions to Quantify Turnover in Biodiversity

Yuan, Yuan; Buckland, Stephen T.; Harrison, Phil J.; Foss, Sergey; Johnston, Alison


Quantifying species turnover is an important aspect of biodiversity monitoring. Turnover measures are usually based on species presence/absence data, reflecting the rate at which species are replaced. However, measures that reflect the rate at which individuals of a species are replaced by individuals of another species are far more sensitive to change. In this paper, we propose families of turnover measures that reflect changes in species proportions. We study the properties of our measures, and use simulation to assess their success in detecting turnover. Using data on the British farmland bird community from the breeding bird survey, we evaluate our measures to quantify temporal turnover and how it varies across the British mainland.Supplementary materials accompanying this paper appear on-line.
