“…We found that sites with low species richness were the most unique (Table ), a pattern also originally observed by Legendre & De Cáceres (), supporting the idea that site uniqueness is not synonymous with high species richness, but rather is indicative of a biota that is uncommon at other sites. This finding is similar to those of other studies (Heino & Grönroos, ; Heino et al., ; Vilmi, Karjalainen, & Heino, ) and, in general, indicates the importance of beta diversity to conservation planning (Socolar, Gilroy, Kunin, & Edwards, ). Such uncommon or more unique biotas are associated mainly with soils with lower clay content, which are present in the lowlands of the Ducke Reserve.…”

“…To our knowledge, no study has thus far analysed patterns of ecological uniqueness of several taxonomic groups sampled at the same sites. We also note that few studies have modelled the LCBD values, even in the univariate case (Heino et al., ; Legendre & De Cáceres, ; da Silva & Hernández, ). Our study is the first attempt to understand the ecological uniqueness values estimated for several biological groups by analysing the variation in LCBD values in a single analysis, rather than conducting a separate analysis for each biological group.…”

Aim We analysed beta‐diversity patterns of various biological groups simultaneously, from the perspective of site ecological uniqueness. We also investigated whether ecological uniqueness variation could be explained by variations in environmental conditions and spatial variables. Data Central Amazonia. Methods We estimated the total beta diversity and ecological uniqueness for 14 biological groups, including plants and animals, sampled at the same sites on a mesoscale in central Amazonia, Brazil. The uniqueness values for all biological groups were combined in a single matrix (multi‐taxa matrix of site uniqueness), which was then used as a response variable matrix in a partial redundancy analysis. We also investigated differences in the uniqueness patterns between plant and animal groups. Results In general, plants showed higher total beta diversity than animals. For plants, uniqueness was explained mainly by environmental conditions, while for animals, uniqueness was also related to spatial variables. Although variation in uniqueness was mainly related to soil clay content, it is difficult to determine a single major environmental variable underlying the variation in uniqueness because the topographical gradient influences many of them, including soil clay content. Main Conclusion The uniqueness values were higher in low‐lying areas, indicating that near‐stream sites were more ecologically unique. Despite the lower number of species in the lowlands, their unique biota contributed strongly to the maintenance of the total beta diversity of the area. This finding should be considered in conservation plans that aim to represent and preserve the regional biota. Our approach proved to be useful to analyse and compare the ecological uniqueness of multiple taxa.

“…It thus appears that among the autotrophs, taxonomically unique species‐poor communities prevail in specific ecological conditions, such as those found in acidic ponds. The negative LCBD–richness correlation observed here has been reported previously for larger organisms, such as freshwater fish (Legendre & De Cáceres, ) and urban pond insects (Heino et al, ). However, we also observed a positive relationship between LCBD and richness for non‐cyanobacteria, which clearly suggested that the negative LCBD–richness correlation is not a general rule when multiple taxa are considered.…”

Aim: Elevational biodiversity patterns are understudied in high-latitude aquatic systems, even though these systems are important for detecting very early impacts of climatic changes on Earth.The aim of this study was to examine the elevational trends in species richness and local contribution to beta diversity (LCBD) of three biofilm microbial groups in freshwater ponds and to identify the key mechanisms underlying these patterns.Location: One hundred and forty-six ponds in subarctic Finland and Norway distributed across the tree line along an elevational gradient of 10-1,038 m a.s.l., spanning from forested landscape to barren boulder fields.Time period: July-August 2015.Major taxa studied: Diatoms, cyanobacteria and non-cyanobacteria.Methods: Generalized linear models were used to identify the most important pond variables explaining richness and LCBD. Structural equation models were used to explore the direct and indirect effects of multiscale drivers on richness and LCBD.Results: Diatom and cyanobacteria richness showed unimodal elevational patterns, whereas noncyanobacteria richness decreased with increasing elevation. The LCBD-elevation relationship was U-shaped for all three microbial groups. Diatom and cyanobacteria richness and LCBD were best explained by local pond variables, especially by pH. Non-cyanobacteria richness and LCBD were related to pond variables, elevation as a proxy for climatic conditions, and normalized difference vegetation index as a proxy for terrestrial productivity.

“…Walls and buildings provide complex and impermeable vertical structures, and roads are a source of invertebrate mortality (from road traffic) as well as a physical barrier, which reduces the opportunity for successful dispersal and colonisation of macroinvertebrates. Complex structural mosaics may limit dispersal to such an extent that macroinvertebrate communities in some urban ponds may be separated from any species pool effect (spatial effects) on local communities (Heino et al 2017). However, many urban ponds exist in networks, where they are linked through urban parks/nature reserves and blue/green corridors (Dallimer et al 2012;Hassall 2014).…”

“…While there has been increasing research on nestedness and turnover in non-urban areas (e.g., Brendonck et al 2015;Viana et al 2016) there has been little research attention focussed on the organisation of beta-diversity in highly disturbed environments such as urban ponds. Urban ponds may demonstrate a different spatial organisation of biodiversity compared to non-urban ponds given the very different architecture and levels of disturbance (Heino et al 2017). Examining and understanding beta-diversity within and among pond assemblages within urban settlements could inform the future placement and design of sites, supporting networks of protected aquatic habitats (city parks or urban wildlife conservation areas) and the management of invasive species within urban areas at an inter-city scale (Socolar et al 2016).…”

Community heterogeneity of aquatic macroinvertebrates in urban ponds at a multi-city scale

Purpose Urbanisation is a leading cause of biotic homogenisation in urban ecosystems. However, there has been little research examining the effect of urbanisation and biotic homogenisation on aquatic communities, and few studies have compared findings across different urban landscapes. We assessed the processes that structure aquatic macroinvertebrate diversity within five UK cities and characterise the heterogeneity of pond macroinvertebrate communities within and among urban areas. Methods A total of 132 ponds were sampled for invertebrates to characterise biological communities of ponds across five UK cities. Variation among sites within cities, and variation among urban settlements, was partitioned into components of beta diversity relating to turnover and nestedness.Results We recorded 337 macroinvertebrate taxa, and species turnover almost entirely accounted for the high beta-diversity recorded within each urban area and when all ponds were considered. A total of 40% of all macroinvertebrates recorded were unique to a particular urban settlement. In contrast to the homogenisation of terrestrial and lotic communities in urban landscapes reported in the literature, ponds support highly heterogeneous communities within and among urban settlements. Conclusions The high species turnover (species replacement) recorded in this study demonstrates that urban pond biodiversity conservation would be most 123Landscape Ecol (2018) 33:389-405 https://doi.org/10.1007/s10980-018-0608-1 efficient at a landscape-scale, rather than at the individual ponds scale. Pond conservation practices need to consider the spatial organization of ecological communities (landscape-scale) to ensure that the maximum possible biodiversity can be protected.
