“…Therefore, a special role in urban areas is attributed to such green areas, which accumulate vast numbers of flowering plants. The primary, but not the only factor which affects the abundance of bumblebees, is flora richness (Widmer and Schmid-Hempel 1999;Steffan-Dewenter et al 2002;Diaz-Ferero et al 2012;Sikora and Kelm 2012;Sikora et al 2016). It also turns out that not only do habitat characteristics have an impact on bumblebees biodiversity, but also factors in the spatial landscape scale, such as the areas which surround particular habitats (Hatfield and LeBuhn 2007).…”

Based on current research the agglomerations are potentially desirable habitats for bumblebees. However, the relationship between the biodiversity of these bees and the green areas where they live is poorly understood. The aim of the study was to estimate the influence of green areas (ranging from 8 to 102 ha) of big cities on bumblebee species richness, composition, and the relative number of these insects. The studies were conducted within the administrative borders of the city of Wrocław (Poland) in 2011-2012 in 12 green areas such as parks, cemeteries and other places with trees and shrubs. Species richness and abundance of bumblebees was determined by direct observation during 30 min. The gathered materials were used to calculate how areas of urban green space affected qualitative and quantitative bumblebee community structure. In total, 13 species of bumblebees (Bombus Latr.) were recorded, of which 3 belonged to cuckoo bumblebees (Psithyrus subgenus). The share of the most similar groups was congregated in green areas not smaller than 30 ha. This was proved by analysis of qualitative structure (Sørensen index), quantitative structure (Renkonen index), and qualitative-quantitative structure (Cody's index). The number of bumblebee species in the surveyed green areas (r = 0.7497) was decisive for the arrangement of the mutual similarity of group structure. Green urban areas should be created in a size of at least 30 ha. Such sites provide conditions for the most diversified bumblebee species communities. Sites smaller than 30 ha can play an important role as refuges, and allow migration to all pollinators.

“…Increasing bee species richness is often linked to floral species richness [23], which frequently increases with the degree of urbanization [4,24,25]. Within a city, urban greenspaces offer a varied breadth and quality of dietary resources [12,[26][27][28][29]. Exotic plant species can make up a substantial portion of the floral resources found in urban areas [30].…”

Unique Bee Communities within Vacant Lots and Urban Farms Result from Variation in Surrounding Urbanization Intensity

We investigated the relative importance of vacant lot and urban farm habitat features and their surrounding landscape context on bee community richness, abundance, composition, and resource use patterns. Three years of pan trap collections from 16 sites yielded a rich assemblage of bees from vacant lots and urban farms, with 98 species documented. We collected a greater bee abundance from vacant lots, and the two forms of greenspace supported significantly different bee communities. Plant-pollinator networks constructed from floral visitation observations revealed that, while the average number of bees utilizing available resources, niche breadth, and niche overlap were similar, the composition of floral resources and common foragers varied by habitat type. Finally, we found that the proportion of impervious surface and number of greenspace patches in the surrounding landscape strongly influenced bee assemblages. At a local scale (100 m radius), patch isolation appeared to limit colonization of vacant lots and urban farms. However, at a larger landscape scale (1000 m radius), increasing urbanization resulted in a greater concentration of bees utilizing vacant lots and urban farms, illustrating that maintaining greenspaces provides important habitat, even within highly developed landscapes.to urban gradients [16,17]. At the same time, landscape features at the city-wide scale can act as strong environmental filters, influencing if taxa from a given species pool are able to colonize distinct greenspace patches [12]. For instance, isolation from other greenspaces can lead to reduced bee species richness within urban forest fragments [18] and connectivity with other greenspaces positively predicts bee abundance on green roofs [19]. In some cases, landscape variables also influence the functional trait distribution found within groups [17,20]. For instance, highly fragmented urban landscapes tend to favor smaller species and cavity nesting species [21,22].At a local scale, species interactions among bees and floral resources can drive patterns of pollinator community assembly [12]. Increasing bee species richness is often linked to floral species richness [23], which frequently increases with the degree of urbanization [4,24,25]. Within a city, urban greenspaces offer a varied breadth and quality of dietary resources [12,[26][27][28][29]. Exotic plant species can make up a substantial portion of the floral resources found in urban areas [30]. Although some exotic species common within vacant lots have been found to be highly attractive [31,32], these resources may also be most suitable for polylectic [33] and/or exotic bees [31]. Urban agroecosystems are likely to have a wider breadth of floral resources, including food crops, native and exotic ornamentals, and many of the same weedy species found in vacant lots. Adding flowering resources, principally native species aimed at supporting pollinators and other beneficial insects, increases available nectar and pollen resources [34] and results in a greater richness and ...

El Jardín Botánico de Bogotá José Celestino Mutis tiene una amplia colección de plantas vivas, con la que se promueve la investigación y conservación ex situ de la flora, con énfasis en la región andina, y que es visitada continuamente por la ciudadanía. En años recientes, se fortaleció la sistematización, georreferenciación, enriquecimiento y señalización de los individuos en las diferentes zonas del Jardín. En especial, el desarrollo de bases de datos y la aplicación de tecnologías de la información han permitido la actualización del inventario. La base de datos de la colección abarca 19 546 accesiones georreferenciadas, que corresponden a 184 familias, 723 géneros y 1185 especies de plantas, entre las que están 89 en categorías de amenaza a nivel nacional. Se sugiere continuar con la documentación de nuevos individuos, y aumentar el nivel de determinación taxonómica. Además, seguir con el mantenimiento y mejora de las bases de datos de la Colección Viva y avanzar en su interoperabilidad con otras bases, como las colecciones de referencia, y evaluar estrategias de publicación.
