“…There is strong evidence that these practices have disrupted communities, leading to pools of generalist species in heavily modified habitats via the exclusion, through filtering, of species with narrower environmental requirements (i.e., specialists) (McKinney, 2006;Vellend et al, 2007;Clavel et al, 2011;Flohre et al, 2011;Barnagaud et al, 2017;Hagen et al, 2017). Thus, in anthropogenic landscapes (such as those that occur across much of the United Kingdom), turnover is predicted to be low across large spatial scales, and communities are predicted to become more nested, with high redundancy in functional diversity (Liang et al, 2019;Weideman et al, 2020).…”

Identifying the Drivers of Spatial Taxonomic and Functional Beta-Diversity of British Breeding Birds

Spatial variation in community composition may be driven by a variety of processes, including environmental filtering and dispersal limitation. While work has been conducted on the relative importance of these processes on various taxa and at varying resolutions, tests using high-resolution empirical data across large spatial extents are sparse. Here, we use a dataset on the presence/absence of breeding bird species collected at the 10 km × 10 km scale across the whole of Britain. Pairwise spatial taxonomic and functional beta diversity, and the constituent components of each (turnover and nestedness/richness loss or gain), were calculated alongside two other measures of functional change (mean nearest taxon distance and mean pairwise distance). Predictor variables included climate and land use measures, as well as a measure of elevation, human influence, and habitat diversity. Generalized dissimilarity modeling was used to analyze the contribution of each predictor variable to variation in the different beta diversity metrics. Overall, we found that there was a moderate and unique proportion of the variance explained by geographical distance per se, which could highlight the role of dispersal limitation in community dissimilarity. Climate, land use, and human influence all also contributed to the observed patterns, but a large proportion of the explained variance in beta diversity was shared between these variables and geographical distance. However, both taxonomic nestedness and functional nestedness were uniquely predicted by a combination of land use, human influence, elevation, and climate variables, indicating a key role for environmental filtering. These findings may have important conservation implications in the face of a warming climate and future land use change.

“…More specifically, it appears that less tolerant specialist species are being progressively replaced by more tolerant generalist species (McKinney and Lockwood, 1999;Devictor et al, 2008). Biotic homogenization has been seen at large spatial scales for different types of diversity and taxa (ants: Ribeiro-Neto et al, 2016;Heuss et al, 2019;birds: Barnagaud et al, 2017;White et al, 2018;Liang et al, 2019;fishes: Nowakowski et al, 2018;and multitrophic organisms: Gossner et al, 2016) even when there is also evidence of local-scale heterogenization (White et al, 2018). With regards to the fourth hypothesis, taxonomic, functional, and phylogenetic diversity all reflected that communities were being heterogenized at the local landscape scale; in contrast, there was mixed support for community homogenization at the regional scale.…”

Biotic homogenization-the erosion of biological differences among ecosystems due to human disturbance-is a pervasive threat to forest landscapes given the current global biodiversity crisis. In Mediterranean forests, wildfire is a particularly common disturbance that affects biodiversity at local, regional, and global scales. However, little is known about how fire influences biotic homogenization. We analyzed the taxonomic, functional, and phylogenetic β-diversity of ground-dwelling ant communities across a large region in the Mediterranean. We tested the hypothesis that fire leads to community heterogenization at the local landscape scale and community homogenization at the regional landscape scale. We sampled ant communities in five pairs of burned and unburned plots at 21 study sites (n = 210 plots) representing seven forest types in Catalonia (northeastern Iberian Peninsula). Ant species were characterized based on 10 functional traits and phylogenetic relatedness. We then calculated taxonomic, functional, and phylogenetic community dissimilarity indices at local and regional landscapes scales focusing on common vs. rare species. Our results show that fire strongly affected community dissimilarity at the local landscape scale. Regardless of diversity type or species type, community dissimilarity was always greater among burned and unburned plots combined than among unburned plots alone, a pattern that was largely driven by Pinus nigra forests, Quercus ilex forests, and shrublands composed of resprouter species. At the regional landscape scale, community dissimilarity was the same among burned and unburned plots and among unburned plots. However, when we examined taxonomic data for common species and phylogenetic data for rare species, community dissimilarity was slightly lower among burned plots than it was among unburned plots and among burned and unburned plots. Fire clearly affected the degree of biotic homogenization within ant communities, and these effects depended on spatial scale, local vegetation type, diversity type, and species type. Overall, our results suggest Arnan et al.Ant Diversity Following Forest Fire that, in Mediterranean regions composed of diverse forest types, wildfire generates local environmental heterogeneity and, as a consequence, locally heterogeneous ant communities. These effects are more dramatic in forest types where fire increases habitat openness. At the regional scale, fire does not create heterogeneity and might even render ant communities more homogeneous.

“…McGill et al, 2006), but functional similarity and uniqueness have only recently received more attention (e.g. Gámez-Virués et al, 2015;Liang et al 2019). Functional homogenisation, which refers to a loss of specialised species or entire functional groups (Olden et al, 2004), is directly linked to ecosystem functions and indirectly to ecosystem services through the loss of functional diversity (Clavel et al, 2011).…”

Changes in the functional features of macrophyte communities and driving factors across a 70-year period

Functional homogenisation occurs across many areas and organism groups, thereby seriously affecting biodiversity loss and ecosystem functioning. In this study, we examined how functional features of aquatic macrophytes have changed during a 70-year period at community and species levels in a boreal lake district. At the community level, we examined if aquatic macrophyte communities showed different spatial patterns in functional composition and functional richness in relation to main environmental drivers between the time periods. We also observed each species in functional space to assess if species with certain sets of traits have become more common or rare in the 70-year study period. We found changes in the relationship between functional community composition and the environment. The aquatic macrophyte communities showed different patterns in functional composition between the two time periods, and the main environmental drivers for these changes were partly different. Temporal changes in functional richness were only partially linked to concomitant changes in the environment, while stable factors were more important. Species' functional traits were not associated with commonness or rarity patterns. Our findings revealed that functional homogenisation has not occurred across these boreal lakes, ranging from small oligotrophic forest lakes to larger lakes affected by human impacts.
