“…The most abundant aphidophagous native species captured were B. ursina , C. maculata, and C. munda . This composition of alien and native species reflects contemporary communities collected from croplands and urban greenspaces in the region (Gardiner et al., 2012, 2014; Parker et al., 2020; Smith & Gardiner, 2013a). For example, in urban vacant lots, Parker et al.…”

“…Thickness of the lines indicate the strength of the association between the two variables, with thicker lines having a stronger similarity value. Relevance network similarity values for lady beetle community metrics are provided in Table 3 species reflects contemporary communities collected from croplands and urban greenspaces in the region (Gardiner et al, 2012(Gardiner et al, , 2014Parker et al, 2020;Smith & Gardiner, 2013a). The Habitat Compression Hypothesis predicts that native aphidophagous coccinellids will occur at low frequencies in agricultural habitats, where alien species are superior competitors, and persist in natural habitats where competition from alien species is relaxed (Alyokhin & Sewell, 2004;Bahlai et al, 2015;Evans, 2000Evans, , 2004Evans et al, 2011).…”

“…For example, in urban vacant lots, Parker et al. (2020) found that alien species dominated the coccinellid fauna representing 74% of captured specimens, and B. ursina , C. maculata , and C. munda were the most common aphidophagous native species collected from these sites. Nonetheless, even the most abundant aphidophagous native taxa captured by our community science survey could be experiencing population decline.…”

“…Our findings align with those from central Chile, where urbanization intensity was a negative driver of aphidophagous native abundance, native richness, and coccinellid body size within parks across a rural to urban landscape gradient (Grez et al., 2019). Likewise, increased impervious surface was negatively associated with lady beetle species richness within urban gardens in Berkshire, England (Rocha et al., 2018), and native and alien lady beetle abundance within vacant lots in Cleveland, Ohio (Parker et al., 2020). In contrast to aphidophagous species, Buckeye Lady Beetle Blitz volunteers found positive relationships between the density of the built environment and the abundance of coccidophagous and fungivorous lady beetles within their gardens.…”

“…The “Habitat Compression Hypothesis” suggests that exploitative competition from alien species for shared aphid prey has resulted in a “compression” of the foraging habitats some native lady beetles are able to exploit (Alyokhin & Sewell, 2004; Bahlai et al., 2015; Evans, 2000, 2004; Evans et al., 2011). This hypothesis predicts that native aphidophagous lady beetles are likely to occur at low frequencies in agricultural and urban habitats where alien species are superior competitors and will be more likely to persist in natural habitats where alien species are less common (Bahlai et al., 2015; Evans, 2004; Grez et al., 2013; Parker et al., 2020). Support for the Habitat Compression Hypothesis was found in central Chile, where the proportion of alien to native coccinellid individuals increased across a disturbance gradient that included agricultural and natural habitats (Grez et al., 2013).…”

Understanding causes of insect population declines is essential for the development of successful conservation plans, but data limitations restrict assessment across spatial and temporal scales. Museum records represent a source of historical data that can be leveraged to investigate temporal trends in insect communities. Native lady beetle decline has been attributed to competition with established alien species and landscape change, but the relative importance of these drivers is difficult to measure with short‐term field‐based studies. We assessed distribution patterns for native lady beetles over 12 decades using museum records, and evaluated the relative importance of alien species and landscape change as factors contributing to changes in communities. We compiled occurrence records for 28 lady beetle species collected in Ohio, USA, from 1900 to 2018. Taxonomic beta‐diversity was used to evaluate changes in lady beetle community composition over time. To evaluate the relative influence of temporal, spatial, landscape, and community factors on the captures of native species, we constructed negative binomial generalized additive models. We report evidence of declines in captures for several native species. Importantly, the timing, severity, and drivers of these documented declines were species‐specific. Land cover change was associated with declines in captures, particularly for Coccinella novemnotata which declined prior to the arrival of alien species. Following the establishment and spread of alien lady beetles, processes of species loss/gain and turnover shifted communities toward the dominance of a few alien species beginning in the 1980s. Because factors associated with declines in captures were highly species‐specific, this emphasizes that mechanisms driving population losses cannot be generalized even among closely related native species. These findings also indicate the importance of museum holdings and the analysis of species‐level data when studying temporal trends in insect populations.

Funding and financing challenges remain a persistent barrier to implementing nature‐based solutions that enhance ecosystem services, facilitate adaptation to climate change, and combat environmental stressors in cities. In the absence of adequate public financial resources, private funds are often expected to fill the gap. But market‐driven, nature‐based solutions can contribute to an inequitable distribution of urban ecosystem services by focusing on net benefits provided by nature. To help foster sustainable development and ensure that nature‐based solutions reach diverse and historically marginalized populations and communities, this scoping review explores the ecosystem services provided by nature‐based solutions and the payment mechanisms that produce and maintain them, focusing on literature on the United States. Findings suggest that the net benefits provided by nature‐based solutions and the available payment mechanisms vary based on the solution utilized (e.g., urban trees, parks, community gardens). Further, the distribution of benefits from nature‐based solutions is influenced by local historical, cultural, political, economic, and environmental contexts, the voices included in decision‐making, and the payment mechanisms used. Inspired by social equity principles, we present a framework for ecosystem service provision that is sensitive to market‐driven funding, financing, and partnerships. Practitioners can use this framework to assess whether payment schemes work in tandem with place (the local context) and process (governance and planning approaches) to ameliorate or exacerbate disparities in nature‐based solutions and the benefits they provide to people.
