Fascination and Joy: Emotions Predict Urban Gardeners’ Pro-Pollinator Behaviour
2021Ulrike Sturm, Tanja M. Straka, Alexandra Moormann, Monika Egerer · Insects · Germany (Berlin)
This study surveyed 111 community gardeners in Berlin and Munich, Germany, to understand the socio-psychological factors predicting pro-pollinator behavior. Using generalized linear models, the analysis revealed that gardeners who were fascinated by pollinators, held positive attitudes, and felt joy about seeing them reported intentions to protect or support pollinators. This suggests that fascination and joy can be harnessed for pollinator research and conservation efforts.

2020Paul Sherfey · Budkavlen · Global
This study explores human-animal relationships, particularly with insects, in collective gardens through observation and digital research. It demonstrates that in collective gardens, cultivating community is as important as cultivating organic produce, and this community includes not only humans but also animal species like insects. The article analyzes why gardeners show interest in building hotels and cafes, sowing meadows, and arranging festivals for insects, especially bees, and contrasts discourses about bees with the lack of similar discourse about wasps, considering how different cultural heritages affect the value placed on species.
CommunityBiodiversityPollinatorsOrganic cycleOpportunities and threats for pollinator conservation in global towns and cities
2020Katherine C. R. Baldock · Current Opinion in Insect Science · Global
Urban expansion is a major threat to biodiversity, yet some pollinator groups, particularly bees, can thrive in urban areas. Recent studies indicate that local floral resources and the amount of impervious cover influence pollinator abundance, richness, and community composition. Urban intensification, chemicals, climate change, and increased honey bee colony densities all negatively affect urban pollinators.
BiodiversityPollinatorsCommunityLandscape and local site variables differentially influence pollinators and pollination services in urban agricultural sites
2019Bennett A.B., Lovell S. · PLoS ONE, 14(2):e0212034 · United States (Chicago)
A study of 19 urban agricultural sites in Chicago examining how surrounding land cover (landscape scale) and on-site design (local scale) shape bees and pollination services. Bee responses varied by body size and nesting habit: increasing impervious cover lowered bee richness and reduced pollination services, while more local floral area boosted small soil-nesting bees. It recommends minimizing impervious cover at large scales and adding floral resources locally so urban agriculture can conserve pollinators in the surrounding ecosystem.

2019Monika Egerer, Jacob M. Cecala, Hamutahl Cohen · Sustainability · United States (California)
This study compared the effects of local and landscape features on wild bee species abundance and richness in 19 gardens and 11 nurseries in California, USA. Local features such as floral richness and ground cover, and landscape features like impervious land cover, were assessed. In gardens, floral richness, local habitat size, and urban land cover impacted wild bee species richness, while in nurseries, floral richness and the proportion of native plant species impacted wild bee abundance and richness.
BiodiversityPollinatorsCommunitySeasonal Occurrences and Species Composition of <i>Orius</i> spp.（Hemiptera: Anthocoridae）in an Okra Field of Kawasaki City
2019M. Tsuruta, Kyo Itoyama · Japanese Journal of Applied Entomology and Zoology · Japan (Kawasaki City)
This study investigated the seasonal occurrences and species composition of Orius spp. in an okra field in Kawasaki City, Japan. Orius spp. were found on okra plants from early-summer to early-autumn, with peak occurrences advancing with earlier flowering times. The initial occurrence was not associated with the seasonal prevalence of thrips on okra plants, suggesting that the main factors influencing Orius spp. occurrence are prey-independent.

2018Gail Ann Langellotto, Andony Melathopoulos, Isabella Messer, Aaron Anderson, Nathan McClintock, Lucas Costner · Sustainability · United States (Portland, Oregon)
This study sampled bees from gardens in the Portland, Oregon metropolitan area and estimated typical foraging distances to assess whether urban gardens might supply pollination services to surrounding agricultural land. It estimates that when pollination-dependent crops are nearby, 30–50% of the garden bee community could potentially provide pollination services to adjacent crops, suggesting urban gardens could provision neighboring farms or serve as a refuge for pollinators.
PollinatorsBiodiversityUnder the Microscope – Answer
2018Trevor A Lambkin · Metamorphosis Australia magazine of the Butterfly & Other Invertebrates Club · Australia
This article discusses native bees, noting their weak jaws result in a tickle-like bite and that indigenous peoples globally have extracted their honey for various uses. Research into native bees for crop pollination began in 1984, leading to the development of hive propagation techniques by 1987. The keeping of native bees, particularly the subtropical Carbonaria species, has since gained popularity among various groups including schools and community gardens.
