Abstract Urban ecosystems can sustain populations of wild bees, partly because their rich native and exotic floral resources. A better understanding the urban bee diet, particularly at larval stage, is necessary to understand biotic interactions feeding behaviour in ecosystems, promote bees by improving management We investigated diet distribution patterns four solitary species with different specialization (i.e. Chelostoma florisomne , Osmia bicornis cornuta Hylaeus communis ) along...
Abstract Urban beekeeping is booming, heightening awareness of pollinator importance but also raising concerns that its fast growth might exceed existing resources and negatively impact urban biodiversity. To evaluate the magnitude sustainability, we analysed data on beehives available in 14 Swiss cities 2012–2018 modelled sustainability under different scenarios floral carrying capacities. We found large increases hives numbers across all from an average 6.48 per km 2 (3139 total) 2012 to...
Cities are socioecological systems that filter and select species, therefore establishing unique species assemblages biotic interactions. Urban ecosystems can host richer wild bee communities than highly intensified agricultural areas, specifically in resource-rich urban green spaces such as allotments family gardens. At the same time, beekeeping has boomed many European cities, raising concerns fast addition of a large number managed bees could deplete existing floral resources, triggering...
Animal biodiversity in cities is generally expected to be uniformly reduced, but recent studies show that this modulated by the composition and configuration of Urban Green Areas (UGAs). UGAs represent a heterogeneous network vegetated spaces urban settings have repeatedly shown support significant part native diurnal animal biodiversity. However, nocturnal taxa so far been understudied, constraining our understanding role on maintaining ecological connectivity enhancing overall We present...
Abstract Wild bees are critical for multiple ecosystem functions but currently threatened. Understanding the determinants of spatial distribution wild bee diversity is a major research gap their conservation. We modeled α and β taxonomic functional in Switzerland to uncover countrywide patterns determine extent which they provide complementary information, assess importance different drivers structuring diversity, identify hotspots overlap between network protected areas. used site‐level...
Abstract Urban ecosystems are formed by pronounced socio‐ecological gradients, which distinct from other and can simultaneously filter promote taxa, ultimately affecting their interactions. However, the strength of effect filtering facilitation across different trophic levels could vary among biotic abiotic factors. Here, we investigate effects habitat amount, temperature host‐enemy interactions in shaping communities cavity‐nesting bees wasps natural enemies. We installed trap‐nests 80...
Cities are human dominated ecosystems providing novel conditions for organisms. Research on urban biodiversity is rapidly increasing, yet it still hampered by the partial spatial coverage of cities and because existing taxonomic biases. Predictive models have proved to be a key tool solve this shortfall. However, predictive rarely been used in due either lack sufficient species records or high-quality predictors (e.g. meaningful ecological maps). Here, we assemble large cross-taxa inventory...
This article summarizes the data of a survey flowering plants in 80 sites five European cities and urban agglomerations (Antwerp, Belgium; greater Paris, France; Poznan, Poland; Tartu, Estonia; Zurich, Switzerland). Sampling were selected based on double orthogonal gradient size connectivity green areas (e.g. parks, cemeteries). To characterize plants, two sampling methodologies applied between April July 2018. First, floristic inventory occurrence all cities. Second, flower counts plots...
Promoting urban green spaces is an effective strategy to increase biodiversity in cities. However, our understanding of how local and landscape factors influence trophic interactions these contexts remains limited. Here, we sampled cavity-nesting bees wasps their natural enemies within 85 gardens Zurich (Switzerland) identify associated with the diversity dissimilarity antagonistic communities. The proportions built-up area at small scales (50 m radius), as well management intensity, sun...
Abstract The phyllosphere harbours a diverse and specific bacterial community, which influences plant health ecosystem functioning. In this study, we investigated the impact of urban green areas connectivity size on composition diversity communities. Hereto, evaluated communities 233 Platanus x acerifolia Acer pseudoplatanus trees in 77 throughout 6 European cities. community significantly differed between cities but only to limited extent tree species. We could show that intensity...
Environmental pressures on species can cascade within food webs and even extend beyond individual ecosystems to interconnected systems at large spatial scales. To facilitate the exploration of these dynamics, we construct a data-based national trophic meta-food web (henceforth metaweb), that includes well-documented vertebrates, invertebrates, vascular plants Switzerland's boundaries, compiles 160 years ecological knowledge. We additionally use combination taxonomic geographic information...
Anthropogenic ecosystems can alter individual functions and ecological processes such as resource use species interactions. While variability on morphological traits involved in diet has been observed between urban non-urban populations of pollinators, the consequences dietary pollen transportation patterns remain poorly understood. Here, we investigate breadth rural individuals two bumblebee for nutrient intake transportation. We show that bumblebees exhibit a broader than their...
Urbanization poses threats and opportunities for the biodiversity of wild bees. At same time, cities can harbor diverse bee assemblages, partly due to unique plant assemblages that provide resources. While dietary preferences have been investigated in various studies, studies conducted mostly nonurban ecosystems data based on visitation observations or palynological techniques. This set describes larval food four species (i.e., Chelostoma florisomne, Hylaeus communis, Osmia bicornis, O....
Abstract Urban ecosystems are associated with socio-ecological conditions that can filter and promote taxa. However, the strength of effect ecological filtering on biodiversity could vary among biotic abiotic factors. Here, we investigate effects habitat amount, temperature, host-enemy interactions in shaping communities cavity-nesting bees wasps (CNBW) their natural enemies. We installed trap-nests 80 sites distributed along urban intensity gradients 5 European cities (Antwerp, Paris,...
an average 10.14 hives per km 2 (9370 in total)" should have read "an 8.1 (6370 total)".The authors also became aware of inaccurate assumption the original version paper, which incorrectly "we additionally considered different carrying capacity scenarios, ranging from 0.5 to unrealistic value 75 " second last sentence first paragraph section "Assessing sustainability urban beekeeping" under Results.In corrected version, "ranging to" is replaced by 1 avoid confusion.
