Increasing anthropogenic salinisation leads to declines in community diversity, functional diversity and trophic links in mountain streams. The number and order of species in comm must be the same as in tree. In ecology, beta diversity is the ratio between regional and local species diversity. (2005) have recently reviewed two major approaches to analysing and modelling patterns in beta diversity: (1) the ‘raw‐data’ approach, in which various environmental and geographical components of beta diversity are partitioned through some form of canonical analysis (e.g. Ecography, 33 (2010), pp. Methods for making these comparisons are used in other fields of science but we will only address Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username, The concept of ‘change in species composition’ or the question ‘how different are two species assemblages’ may apparently seem straightforward, but, as argued elsewhere (, By continuing to browse this site, you agree to its use of cookies as described in our, I have read and accept the Wiley Online Library Terms and Conditions of Use, beta.sample(x, index.family, sites, samples), Navigating the multiple meanings of beta diversity: a roadmap for the practicing ecologist, Disentangling distance decay of similarity from richness gradients: response to Soininen, Determinants of species richness, endemism and turnover in European longhorn beetles, Partitioning the turnover and nestedness components of beta diversity, The relationship between species replacement, dissimilarity derived from nestedness, and nestedness, A multiple‐site similarity measure independent of richness, Proposing a resolution to debates on diversity partitioning, A check‐list of Longicorn Beetles (Coleoptera, Cerambycoidea) of Europe, Partitioning diversity into independent alpha and beta components, Commentary: do we have a consistent terminology for species diversity?

Raw data were taken from the North American Breeding Bird Survey (http://www.pwrc.usgs.gov/BBS) and have been aggregated to the state level for two time periods (1980–1985 and 2000–2005). EXOTIC SPECIES MODIFY THE FUNCTIONAL DIVERSITY PATTERNS OF FRESHWATER FISH ASSEMBLAGES IN CONTINENTAL CHILE: EXAMINING HISTORICAL AND GEOGRAPHICAL PATTERNS.
