“…In cities, humans alter heterogeneity and connectivity both at the local and regional scales through land development, infrastructure, species introductions and management actions. Coupled together their interaction may shift the relative role of local and regional processes governing community assembly (Swan et al, 2021; Voelker & Swan, 2021). An interesting highlight of our study is the observed increase in beta diversity despite increase in dispersal, which is plausibly explained by the interactions of heterogeneity, connectivity and contingency.…”

Explicit characterisation of the complexity of urban landscapes is critical for understanding patterns of biodiversity and for detecting the underlying social and ecological processes that shape them. Urban environments exhibit variable heterogeneity and connectivity, influenced by different historical contingencies, that affect community assembly across scales. The multidimensional nature of urban disturbance and co‐occurrence of multiple stressors can cause synergistic effects leading to nonlinear responses in populations and communities. Yet, current research design of urban ecology and evolutionary studies typically relies on simple representation of the parameter space that can be observed. Sampling approaches apply simple urban gradients such as linear transects in space or comparisons of urban sites across the urban mosaic accounting for a few variables. This rarely considers multiple dimensions and scales of biodiversity, and proves to be inadequate to explain observed patterns. We apply a multidimensional approach that integrates distinctive social, ecological and built characteristics of urban landscapes, representing variations along dimensions of heterogeneity, connectivity and historical contingency. Measuring species richness and beta diversity across 100 US metropolitan areas at the city and 1‐km scales, we show that distinctive signatures of urban biodiversity can result from interactions between socioecological heterogeneity and connectivity, mediated by historical contingency.

“…While some of them are local (e.g., land consolidation and urbanization), others extend over large spatial scales (e.g., climate change associated stressors), influencing multiple ponds and interfering with the flux of aquatic and semi-aquatic organisms (Hanashiro et al 2019;Chase et al 2020;Voelker and Swan 2021). Recent advancements in metacommunity theory provided answers to some of the interplays between local and global stressors influencing ecosystem patches such as ponds, linking abiotic filtering on communities with dispersal capabilities and limitations (Hanashiro et al 2019;Chase et al 2020;Voelker and Swan 2021). In summary, the effects of stressors across the pondscape depend on the ability of organisms to either tolerate (abiotic filtering) or evade stressors (dispersal processes).…”

“…Therefore, stressors expanding past the tolerance and dispersal range of an organism are likely to induce severe effects and may even lead to local extinctions and drastic diversity reductions (Relyea 2005;Beketov et al 2013). This is particularly problematic as once key taxa have been removed from the regional species pool following filtering, the local and regional recovery of the biodiversity, even after stressor mitigation, may not be possible due to the absence of key dispersers (Voelker and Swan 2021). As aforementioned, connectivity between ponds is a critical determinant of biodiversity in ponds.…”

“…This phenomenon has been coined "biotic differentiation" (Chase et al 2020). By contrast, wide-ranging stressors, such as spread out local management practices or climaterelated stressors, or stressors benefiting tolerant and generalist species over specialists, may lead to biotic homogenization and a decrease in β-diversity (Socolar et al 2016;Chase et al 2020;Voelker and Swan 2021).…”

The ecological role of permanent ponds in Europe: a review of dietary linkages to terrestrial ecosystems via emerging insects

et al. 2023

Permanent ponds are valuable freshwater systems and biodiversity hotspots. They provide diverse ecosystem services (ES), including water quality improvement and supply, food provisioning and biodiversity support. This is despite being under significant pressure from multiple anthropogenic stressors and the impacts of ongoing global change. However, ponds are largely overlooked in management plans and legislation, and ecological research has focused on large freshwater ecosystems, such as rivers or lakes. Protection of ponds is often insufficient or indirectly provided via associated habitats such as wetlands. This phenomenon is likely exacerbated due to lacking a full-scale understanding of the importance of ponds. In this review, we provided a detailed overview of permanent ponds across Europe, including their usages and the biodiversity they support. By discussing the concepts of pondscape and metacommunity theory, we highlighted the importance of connectivity among and between ponds and identified fluxes of emerging insects as another ES of ponds. Those insects are rich in essential nutrients such as polyunsaturated fatty acids (PUFA), which are delivered through them to the terrestrial environment, however the extent and impact of this ES remains largely unexplored. Several potential stressors, especially related to ongoing global change, which influence pond diversity and integrity were discussed. To conclude this review, we provided our insights on future pond management. Adaptive measures, taking into account the pond system per se within the pondscape, were found to be the most promising to mitigate the loss of natural ponds and restore and conserve natural small water bodies as refuges and diversity hotspots in increasingly urbanized landscapes.

“…Existing studies have also shown that species will inevitably respond differently to environments and resources at different spatial scales when making habitat choices [37][38][39][40]. Moreover, the overall habitat quality is usually determined by the interaction of multiple spatial processes at different scales [41][42][43][44][45]. However, existing research still lacks robust theories and methods for establishing mathematical models with "cross-scale" description and interpretation ability.…”

Urban ecosystem dysfunction, habitat fragmentation, and biodiversity loss caused by rapid urbanization have threatened sustainable urban development. Urban habitat quality is one of the important indicators for assessing the urban ecological environment. Therefore, it is of great practical significance to carry out a study on the driving mechanism of urban habitat quality and integrate the results into urban planning. In this study, taking Zhengzhou, China, as an example, the InVEST model was used to analyze the spatial differentiation characteristics of urban habitat quality and Geodetector software was adopted to explore the driving mechanism of habitat quality at different grid-scales. The results show the following: (1) LUCC, altitude, slope, surface roughness, relief amplitude, population, nighttime light, and NDVI are the dominant factors affecting the spatial differentiation of habitat quality. Among them, the impacts of slope, surface roughness, population, nighttime light, and NDVI on habitat quality are highly sensitive to varying grid-scales. At the grid-scale of 1000 to 1250 m, the impacts of the dominant factors on habitat quality is closer to the mean level of multiple scales. (2) The impact of each factor on the spatial distribution of habitat quality is different, and the difference between most factors has always been significant regardless of the variation of grid-scales. The superimposed impact of two factors on the spatial distribution of habitat quality is greater than the impact of the single factor. (3) Combined with the research results and the local conditions of Zhengzhou, we put forward some directions of habitat protection around adjusting urban land use structure, applying nature-based solutions and establishing a systematic thinking model for multi-level urban habitat sustainability.
