“…Interestingly, most of the plants visited by bumble bees in this study were native plants, such as T. repens , R. fruticosus , or L. corniculatus (Table SII). This finding agrees with recent studies that suggest native plant species to promote bee abundance in urban gardens (Pawelek et al 2009;Pardee and Philpott 2014).…”

Plant diversity and composition compensate for negative effects of urbanization on foraging bumble bees

-Bumble bees play an important role as pollinators of many crop plants and wild flowers. As in many wild bees, their abundance and diversity have declined in recent years, which may threaten the stability of pollination services. The observed decline is often linked with the loss or alteration of natural habitat, e.g., through urbanization, the conversion of natural habitat into largely sealed areas (concrete) inhabited by humans. The effects of urbanization on bumble bees remain as yet controversial with both positive and negative effects reported. We investigated how habitat isolation through increasing areas of concrete, as well as the diversity, abundance, and community composition of floral resources, determine bumble bee abundance and diversity in cities. We found plant species diversity and abundance to be more important than the amount of concrete in driving the abundance and species richness of common bumble bees in a German city. Moreover, plant species composition, i.e., the presence of specific plant species and families (e.g., Fabaceae), played a prominent role. In particular, flower-rich parks and gardens can offer a continuous food supply for bumble bees and attract bumble bee foragers even to isolated patches in the city center.bee decline / habitat fragmentation / Hymenoptera / pollination / urban landscape

“…Previous studies suggest that gardens are important for attracting and maintaining populations of urban bees (e.g. Goulson et al 2006;Andersson et al 2007;Fetridge et al 2008;Pawelek et al 2009). The informal management of many gardens and allotments has been suggested as a key in providing bees with suitable habitats (Andersson et al 2007).…”

Bumblebees in the city: abundance, species richness and diversity in two urban habitats

Bumblebees are well known for their contribution to the ecosystem service of pollination. In urban areas, green space management beneficial to pollinators can be an important step in sustaining large urban bee populations. The abundance, number of species and diversity of bumblebees (Bombus spp), as well as the abundance of honeybees (Apis mellifera), were studied in 13 urban gardens (including allotments) and 13 ornamental flowerbeds (in parks and green spaces) in the city centre of Gothenburg, Sweden. In total, 12 species of bumblebees were observed. Species richness was significantly higher in gardens than in flowerbeds, but diversity (Berger-Parker and Simpson indices) was higher in flowerbeds than in urban gardens. The abundance in gardens was significantly higher and approximately twice that found in flowerbeds. The number of honeybee individuals was positively correlated with the abundance of bumblebees. Neither species richness nor abundance of bumblebees was affected by site size. However, a high flowering frequency positively affected the total number of bumblebee and honeybee individuals at the sites. We conclude that urban gardens contribute to sustaining a high abundance of bumblebees in the city centre, and indirectly facilitates small scale urban food production. A pollinator-friendly management of urban green space with plentiful flowering may promote a community of bumblebees with high abundance and diversity.

“…They can also be designed with the goal of attracting specific pollinators, such as bees (Owen 1991;Tommasi et al 2004;McFrederick and Le Buhn 2006;Tait 2006;Fetridge et al 2008;Matteson et al 2008;Wojcik et al 2008;Kearns and Oliveras 2009;Pawelek et al 2009;Matteson and Langellotto 2010), and thus can contribute to conservation of local fauna, especially when utilizing native plant species (McIntyre and Hostetler 2001;McKinney 2002;Cane et al 2006). We recommend that the results of our study should be taken into account in landscape planning within urban areas.…”

“…In recent years, interest in the urban bee fauna has increased (McIntyre and Hostetler 2001;Frankie et al 2005;McFrederick and Le Buhn 2006;Fetridge et al 2008;Matteson et al 2008;Wojcik et al 2008;Pawelek et al 2009). Urbanization causes a drastic and persistent change in the landscape and environment which, in turn, transforms interspecific interactions within communities (McKinney 2006).…”

Wild bees along an urban gradient: winners and losers

The variability of bee communities along an urban gradient has a potentially strong impact on pollinator-plant interactions. We investigated changes in bee species richness and community composition in the city centre and suburbs of Poznań, Poland. During 2006-2008 we recorded 2,495 individuals from 104 species. The most abundant species was Andrena haemmorhoa. Other abundant species were Bombus pascuorum, Andrena vaga, Andrena nitida, Bombus terrestris. Several species appeared to be more abundant in the city centre whereas others showed an opposite tendency. We have found that the urbanized landscape can act as a filter for the bee community since some specific ecological traits facilitate colonization of the city centre. Small-bodied species that start their activity later in the season and are not solitary preferred the city centre. However, bee species diversity and richness remained stable across the urban gradient indicating some advantages of being a city dwelling bee. We suggest that a city can be a very important habitat for a diverse bee fauna and that conservation of a wide range of habitats of different urbanization levels seems to be the most suitable strategy for conservation of bee diversity in cities.
