“…Each transect used to survey the Czech Republic contained 20 census points, with data recorded for 5 min in the morning at approximately 300-m intervals. The transects were visited twice per breeding season by the same observer to sample both early and late breeders (Reif et al, 2013).…”

“…Understanding the turnover of traits in space and time, therefore, has been recognized as an essential area of investigation to determine whether changes in taxonomic turnover are accompanied by changes in functional turnover, or whether functional redundancy may ensure ecosystem functioning is maintained despite losses in taxonomic diversity (Villéger, Grenouillet & Brosse, 2014). Previous studies failed to find a consistent relationship between functional and taxonomic homogenization with results varying between location, environmental pressures, and focal taxa (Abadie, Machon, Muratet & Porcher, 2011; Devictor, Julliard, Couvet, Lee & Jiguet, 2007; Monnet et al., 2014; Reif et al., 2013; Sonnier, Johnson, Amatangelo, Rogers & Waller, 2014). Many of these only use a proxy for functional homogenization, that is, mean community specialization.…”

Environmental change has reshuffled communities often causing taxonomic homogenization rather than differentiation. Some studies suggest that this increasing similarity of species composition between communities is accompanied by an increase in similarity of trait composition—functional homogenization—although different methodologies have failed to come to any consistent conclusions. Functional homogenization could have a large effect on ecosystem functioning and stability. Here, we use the general definition of homogenization as “reduced spatial turnover over time” to compare changes in Simpson's beta diversity (taxonomic turnover) with changes in Rao's quadratic entropy beta diversity (functional turnover) in British breeding birds at three spatial scales. Using biotic and climatic variables, we identify which factors may predispose a site to homogenization. The change in turnover measures between two time periods, 20 years apart, was calculated. A null model approach was taken to identify occurrences of functional homogenization and differentiation independent of changes in taxonomic turnover. We used conditional autoregressive models fitted using integrated nested Laplace approximations to determine how environmental drivers and factors relating to species distributions affect changes in spatial turnover of species and functional diversity. The measurement of functional homogenization affects the chance of rejection of the null models, with many sites showing taxonomic homogenization unaccompanied by functional homogenization, although occurrence varies with spatial scale. At the smallest scale, while temperature‐related variables drive changes in taxonomic turnover, changes in functional turnover are associated with variation in growing degree days; however, changes in functional turnover become more difficult to predict at larger spatial scales. Our results highlight the multifactorial processes underlying taxonomic and functional homogenization and that redundancy in species traits may allow ecosystem functioning to be maintained in some areas despite changes in species composition.

“…More recent efforts have considered a broader suite of potential drivers. For example, logging forest fragmentation was the dominant driver of taxonomic homogenisation in Brazilian Atlantic forests (Lôbo et al 2011) and phylogenetic homogenisation in Cambodian forests (Toyama et al 2015), fish faunal homogenisation of Australia was highly concordant with dam infrastructure (Olden et al 2008) and increasing spring temperatures were associated with bird functional homogenisation in the Czech Republic (Reif et al 2013). Studies have also demonstrated that natural environmental variability can be an important driver of biotic homogenisation and that changing native species ranges, not the invasion of non-native species, can promote community similarity (e.g.…”

In an era of global change, the process of biotic homogenisation by which regional biotas become more similar through time has attracted considerable attention from ecologists. Here, a retrospective look at the literature is taken and the question asked how comprehensive is the understanding of this global phenomenon? The goal is to identify potential areas for additional and future enquiries to advance this research frontier and best ensure the long-term preservation of biological diversity across the world. Six propositions are presented here to; (1) broaden our geographic and taxonomic understanding, (2) diversify the spatial and temporal scales of inquiry, (3) reconcile past and embrace new approaches to quantification, (4) improve our knowledge of the underlying drivers, (5) reveal the conservation implications and (6) forecast future homogenisation. It is argued that significant progress in the understanding of the causes, consequences and conservation implication of biotic homogenisation will come by integrating concepts and approaches from ecology, evolution and conservation across a hierarchy of spatial and temporal scales.
