Abstract Urbanization is a leading threat to biodiversity, but scientifically informed management of urban ecosystems can mitigate negative impacts. For wild bees, which are declining worldwide, careful consideration flower choice in public and private green spaces could help preserve their diversity. While floral density species richness both linked bee diversity, the mechanisms underlying these relationships not fully understood. Here, we tested two hypotheses relating influence trait composition richness, have termed within‐trait diversity optimal hypotheses. Specifically, assessed whether variation relates weighted variance (trait diversity) mean (optimal trait) traits observed across city Montreal, Canada. Our analyses focused on pollinator feeding success: nectar sugar concentration corolla length. After accounting for among sites, was positively related community‐weighted length, supporting hypothesis. These findings suggest that practices increase morphologies promote persistence communities cities.

Our world is becoming increasingly urbanized with a growing human population concentrated around cities. The expansion of urban areas has important consequences for biodiversity, yet the abiotic drivers biodiversity in ecosystems have not been well characterized most diverse group animals on planet, arthropods. Given their great diversity, comparatively small home ranges, and ability to disperse, arthropods make an excellent model studying which factors can accurately predict biodiversity. We assessed effects (i) topography (distance natural ocean) (ii) (mean annual temperature diurnal range), (iii) anthropogenic (land value amount impervious surface) occurrence six arthropod groups represented Malaise trap collections run by BioSCAN project across Greater Los Angeles Area. found striking heterogeneity responses all both within between taxonomic groups. Diurnal range had consistently negative effect occupancy but this was only significant Phoridae. Anthropogenic mixed though mostly insignificant effects, as some species were highly areas, while other showed suppressed diversity. Only Phoridae significantly affected land value, where more likely occur lower value. support high regional spatial community composition dependent group.

ABSTRACT Although Syrphidae is an essential family of flies because they provide key ecosystem services like pollination and pest control, their richness abundance respond negatively to urbanisation, even when high‐quality green spaces are present. These the conclusions many studies from northern hemisphere; however, there shortfalls in our knowledge flower fly ecology Neotropical megacities. We used a 10‐year dataset obtained long‐term citizen science program devoted test whether richness, total number records (as proxy abundance) diversity could be influenced by space predictors such as surface percentage areas, quality public squares parks indices greenness index (NDVI) across 34 municipalities Greater Santiago. Furthermore, we described for first time interaction network exclusively within city. analysed 1084 607 interactions 29 species. found that north‐east have more Based on abundance, two‐way Jaccard analysis grouped into three major clades: (a) those with than 10 species, (b) between five species (c) fewer Generalised linear mixed models associated positively significantly diversity, mainly mean NDVI value.

Abstract Land use change is a major driver of pollinator decline and loss pollination services. For plant interactions to persist in rapidly changing urban systems, co‐occurring species must share matching traits, including phenological, morphological, physiological traits. Thus, the knowledge trait among interacting plants pollinators can aid design habitats enhance conservation value green spaces, but this remains relatively understudied. Here, we review how facilitates persistence creation new plant–pollinator networks. We highlight four drivers facilitating restructuring networks through gain areas. also show different pathways by which traits affected urbanization. Furthermore, functional help predict novel environments, those exotic species. Finally, application management practices, sustainable spaces that will accommodate functionally diverse within matrix.

Despite critical ecosystem services provided by pollinators, rapid pollinator declines occurring in response to anthropogenic activities that cause loss suitable habitat. There is an opportunity urban green space support pollination locally across landscape. However, there a lack practical but evidence-based guidance on how can be designed effectively floral resources other habitat needs diverse assemblage pollinators. We examine existing research this paper address following questions specific insect pollinators temperate settings: (1) Which focus efforts increase cities?

Faced with pollinator declines, cities could serve as refuges for biodiversity conservation by managing floral resources in public green spaces. Ornamental plants play an important role attracting pollinators because they form part of urban management. However, knowledge how their traits respond to drought is lacking, and it unknown whether will be suitable under future climates. The main objective this study was determine the covariation ornamental plant species effects on them. To end, a city greenhouse we measured eight commonly used spaces France. We subjected control treatment or treatment, reducing volume frequency watering. observed interspecific variability among these change between pollen quantity nectar treatment.

Abstract Recent research is increasingly focusing on the significance of urban gardens, agriculture, and rooftop agriculture as viable solutions to address food security issues. The crops cultivated in these settings play a crucial role promoting sustainability. However, considerable number rely pollinators, making them key contributors global security, especially concerning micronutrient content. Therefore, pivotal step planning process for local production involves estimating potential available area agriculture. In this study, we employed species distribution models (SDMs) globally assess major cities' suitability Through creation habitat maps 61 pollinator‐dependent using SDMs, evaluated 1143 cities worldwide cultivate each crops. Our findings reveal that nearly half examined (570) can support 0–10 crops, with approximately 30% (353 cities) able sustain 11–20 Around 14.5% are deemed suitable supporting 21–30 only about 4.5% accommodate between 31 40 Across all studied, it was determined city, average, has 12.5 This represents 20% total percentage (61 crops) considered comprehensive analysis. While our offers valuable insights into researchers planners must approach caution, particularly when extrapolating regions limited crop occurrence data.
