“…Regardless, planting native plants in urban landscapes should be a priority as native plants and their insect herbivores have disproportionately large impacts on the whole food chain (Narango et al. , ) and native plants are intrinsically adapted to the regional environment.…”

Brown. 2020. Localand landscape-scale variables shape insect diversity in an urban biodiversity hot spot. Ecological Applications 30(4):Abstract. Local community structure is shaped by processes acting at local and landscape scales. The relative importance of drivers operating across different spatial scales is difficult to test without observations across regional or latitudinal gradients. Cities exhibit strong but predictable environmental gradients overlaying a mosaic of highly variable but repeated habitat types within a constrained area. Thus, cities present a unique opportunity to explore how both local and landscape factors influence local biotic communities. We used insect communities to examine the interactions among local environmental variables (such as temperature and relative humidity), local habitat characteristics (such as plant community composition), and broad-scale patterns of urbanization (including biophysical, human-built, and socioeconomic variables) on local insect abundance, species richness, and species composition in Los Angeles, a hot, dry, near-desert city. After accounting for seasonal trends, insect species richness and abundance were highest in drier and hotter sites, but the magnitude of local environmental effects varied with the degree of urbanization. In contrast, insect species composition was best predicted by broad-scale urbanization trends, with the more native communities occurring in less urbanized sites and more cosmopolitan insects occurring in highly urbanized sites. However, insect species richness and abundance were >30% higher and insect composition was similar across sites that hosted either native or drought-tolerant plants, regardless of the degree of urbanization. These results demonstrate that urban insect biodiversity is a product of interacting mechanisms working at both local and landscape scales. However, local-scale changes to urban habitats, such as cultivating plants that are adapted to the natural environment nearest the city, can positively impact urban biodiversity regardless of location.

“…4). This suggests that despite comprising > 20% 'ecologically valuable areas' (Vriens et al 2011), local-scale green areas in cities are low-quality habitats -containing nonnative plant species and less preferred dietary items of lower nutritional value (de Satgé unpubl., Narango et al 2018)and are subject to the effects of regional-scale urbanisation (Strohbach et al 2013).…”

While numerous studies have reported negative effects of urbanisation on birds, few have examined the role of urban scale in influencing breeding success. Furthermore, many studies have relied on qualitative rather than quantitative assessments of urbanisation. This study sought to address these issues by testing the effects of urbanisation, measured at two spatial scales, on the breeding success of great tits Parus major. A nested study design, incorporating over 400 nestboxes, was used in study sites across northern Belgium with a priori quantified degrees of urbanisation at both local and regional scales. All measured breeding parameters were found to vary at one or both spatial scales of urbanisation; in more urbanised areas great tits displayed advanced laying dates but lower breeding success compared to rural areas, with smaller clutch sizes, lower nestling masses and fewer fledglings per egg. Importantly, urbanisation effects were not limited to big cities as birds breeding in gardens or parks in small towns also had comparatively low success. We found that both regional‐ and local‐scale urbanisation had consistent significant effects on laying date, clutch size and nestling mass, while the number of fledglings per egg was negatively influenced by local‐scale urbanisation only. Results of this study therefore highlight the importance of utilising multiple spatial scales in analysing urbanisation effects, as well as the potential negative impact of local urbanisation on breeding success. This calls for further investigation into mechanisms driving urbanisation effects and how these may vary at different scales.

“…There is a well-recognized positive correlation between urban plant diversity, vegetation cover, and wealth in cities (Iverson & Cook 2000; Hope et al 2003; Kinzig et al 2005; Leong et al 2018). Higher housing density typically also means more backyards and gardens in people’s yards in a city, and these diverse plant communities can provide important sources of food, cover, and nesting resources for birds (Thompson et al 2003; Smith et al 2005, 2006; Narango et al 2018). In addition to vegetation, cities also provide stable year-round access to food sources via bird feeders and human food waste (Lepczyk et al 2004; Tryjanowski et al 2015) which influences urban bird community structure and breeding success (Robb et al 2008; Galbraith et al 2015).…”

Cities are the planet’s newest ecosystem and thus provide the opportunity to study community formation directly following major permanent environmental change. The human social and built components of environments can vary widely across different cities, yet it is largely unknown how these features of a city covary with the traits of colonizing species. We constructed a new dataset from open-source data with 44,670 observations of 160 Passerine species observed 1,908 urban areas across the United States. We found that as a city’s housing density and median income increased it tended to support more migratory species and species with smaller body sizes and shorter lifespans. This suggests that differential survival and reproduction at the species-level can quickly generate geographical patterns of species trait variation across urban environments similar to those found in natural settings without the need for evolutionary change.
