“…frontalis and E . cordata (Ferreira‐Caliman et al ., 2018; Araújo et al ., 2021). In Germany, bees in urban areas also visited a lower proportion of plant species despite the higher floral sources richness observed in urban areas compared to agricultural lands, which explains the high network‐level specialisation in urban areas (Theodorou et al ., 2017).…”

“…Nonetheless, a higher abundance and richness of non‐native plants may not necessarily widen the range of floral sources to all bee species. Some bees collect pollen only on flowers of native plants (Ferreira‐Caliman et al ., 2018) whereas females of other species avoid alien pollen for brood cell provisioning (MacIvor et al ., 2015). In addition, the plant species used in urban forestry and landscaping may not favour all bees, especially the oligolectic species, which display highly specialised interaction networks (Rocha‐Filho et al ., 2018) and are negatively affected by the prevalence of alien plant species (Threlfall et al ., 2015).…”

1. Urban areas can host speciose bee communities due partially to the species‐rich combination of both native and alien plant species found in these landscapes. However, in intensively‐constructed zones, it could be expected to record a low plant diversity used by bees because of the high proportion of paved surfaces in these areas. 2. We investigated the influence of urbanisation on the cavity‐nesting bee‐plant community and interaction network structures in a medium‐sized city. The floral diversity used by nesting females in cell provisioning was retrieved from the pollen content obtained from trap‐nests collected in 11 sites located in an urban landscape gradient. 3. Eighty pollen types belonging to 20 families were identified in the 155 pollen samples analysed. At least seven alien plant species were identified in samples from all sampling points. The landscape analysis revealed a positive influence of the proportion of green areas on the pollen type richness, although the null model was also selected as best model. Likewise, all network metrics but connectance were not influenced by any of the landscape variables. 4. Our findings demonstrated that notwithstanding the sampling sites the floral diversity used by bees and the alien pollen type richness were similar. Likewise, the bee‐plant networks were modular, asymmetric, and highly specialised. The positive adaptation that cavity‐nesting bee species present in urban environments and the presence of bee species that can explore a diverse flora may indicate that the local variation in the landscape had little influence on their interactions with plants.

“…Euglossa cordata is a widely distributed species in South America and occurs in several ecosystems ranging from pristine forests to open environments and disturbed areas (Raw 1989;Tonhasca et al 2002;Milet-Pinheiro and Schlindwein 2005;Ramalho et al 2009;Aguiar and Gaglianone 2012;Rocha-Filho and Garófalo 2013;Rosa et al 2015;Carneiro et al 2018). Moreover, this species is frequently recorded in cities (López-Uribe et al 2008) and is highly generalist regarding floral resources collection (Ferreira-Caliman et al 2018), what denotes its ecological plasticity and resilience. Likewise, El .…”

Species turnover and low stability in a community of euglossine bees (Hymenoptera: Apidae) sampled within 28 years in an urban forest fragment

Orchid bees are important long-distance pollinators in Neotropical rainforests. Despite their great flight capacity, some species avoid leaving the forest and might be then more vulnerable to the negative effects of habitat fragmentation. Here, we sampled the euglossine fauna from a forest fragment in an urban zone and compared the data to two surveys conducted in the same area 28 and 20 years before. Twelve species were sampled, and the highest values of both abundance and richness were recorded in the present sampling. Species turnover was observed with the resilient species Euglossa cordata and Eulaema nigrita presenting a high increase in number over the years whereas the prevalent species in the former samplings, Euglossa pleosticta , show the highest stable populations. Conversely, the abundance of Euglossa annectans decreased until zero in the last sampling. The studied orchid bee populations had a lower stability value when compared with other euglossine long-term surveys.Our results indicate that even a small forest fragment within an urbanised landscape and subjected to different levels of anthropogenic impacts harbours a diverse euglossine fauna. It is suggested that not only the preservation and maintenance of forest fragments in urban areas but also its restoration after environmental impacts are important procedures to support species-rich wildlife.

“…This division in the literature is exemplified by the two main pollination-related topics, Pollination function and Pollinator biodiversity. The Pollination function topic consisted mostly of papers that measured and tested the interaction between pollinators and flowers and are therefore explicitly studied this process (e.g., Brizola-Bonacina 2014, Faria and Araujo 2016, Ferreira-Caliman et al 2018. In contrast, the Pollinator biodiversity topic, consisted of studies that monitored the responses of pollinator communities (i.e., pollinator biodiversity) to urbanization often at the landscape scale (e.g., Tscheulin et al 2011, Quistberg et al 2016, Bennett and Lovell 2019.…”

Ecological processes associated with different animal taxa in urban environments

Urbanization is increasing globally with wide‐ranging consequences for biodiversity and the ecological processes it performs. Yet knowledge of the range of ecological processes supported by biodiversity in urban environments, and the different taxa that perform these processes is poorly understood. We used a text‐analysis approach to identify the research trends and gaps in knowledge in the literature on ecological processes provided by animals in urban environments. We found a divide in urban ecological processes research that grouped studies into those with an explicit link to ecological processes and those that focused on biodiversity and made an implicit link to ecological processes. We also found that the dominant taxa in urban ecological processes research were insects, which has more than twice as many studies as birds or mammals, potentially due to their recognized and explicit link to key processes and services (e.g., pollination, pollution biomonitoring) and disservices (e.g., pests, disease transmission). We found a further split between terrestrial and aquatic studies, with urban aquatic studies also declining in relative prevalence over the last 20 yr. To consolidate and advance research on ecological processes in urban environments, we suggest it will be important to bridge the divide between studies on explicit services and others on more general biodiversity. This might be achieved by placing greater focus on the processes provided by non‐insect taxa, and by integrating aquatic and terrestrial perspectives.
