UNIVERSITY of READING Delivering Biodiversity and Pollination Services on Farmland
UNIVERSITY OF READING Delivering biodiversity and pollination services on farmland: a comparison of three wildlife- friendly farming schemes Thesis submitted for the degree of Doctor of Philosophy Centre for Agri-Environmental Research School of Agriculture, Policy and Development Chloe J. Hardman June 2016 Declaration I confirm that this is my own work and the use of all material from other sources has been properly and fully acknowledged. Chloe Hardman i Abstract Gains in food production through agricultural intensification have come at an environmental cost, including reductions in habitat diversity, species diversity and some ecosystem services. Wildlife- friendly farming schemes aim to mitigate the negative impacts of agricultural intensification. In this study, we compared the effectiveness of three schemes using four matched triplets of farms in southern England. The schemes were: i) a baseline of Entry Level Stewardship (ELS: a flexible widespread government scheme, ii) organic agriculture and iii) Conservation Grade (CG: a prescriptive, non-organic, biodiversity-focused scheme). We examined how effective the schemes were in supporting habitat diversity, species diversity, floral resources, pollinators and pollination services. Farms in CG and organic schemes supported higher habitat diversity than farms only in ELS. Plant and butterfly species richness were significantly higher on organic farms and butterfly species richness was marginally higher on CG farms compared to farms in ELS. The species richness of plants, butterflies, solitary bees and birds in winter was significantly correlated with local habitat diversity. Organic farms supported more evenly distributed floral resources and higher nectar densities compared to farms in CG or ELS. Compared to maximum estimates of pollen demand from six bee species, only organic farms supplied sufficient pollen in late summer. -

For three years, we sampled second-growth woodlots and apple orchard-adjacent forest Canopy ecology sites from late March to early June every 7–10 days with paired sets of tri-colored pan traps in the canopy (20–25 m above ground) and understory (<1m). Roughly one fifthof the known New York state bee fauna were caught at each height, and 90 of 417 species overall, with many species shared across the strata. We found equal species richness, higher diversity, and a much higher proportion of female bees in the canopy compared to the understory. Female solitary, social, soil- and wood-nesting bees were all abundant in the canopy while soil- nesting and solitary bees of both sexes dominated the understory. -

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

Gardiner * ID Department of Entomology, The Ohio State University, 2021 Coffey Road, Columbus, OH 43210, USA; [email protected] (F.S.S.); [email protected] (S.P.P.) * Correspondence: [email protected]; Tel.: +1-330-601-6628 Received: 1 May 2018; Accepted: 5 June 2018; Published: 8 June 2018 Abstract: 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. -
Diversified Floral Resource Plantings Support Bee Communities After
www.nature.com/scientificreports Corrected: Publisher Correction OPEN Diversifed Floral Resource Plantings Support Bee Communities after Apple Bloom in Commercial Orchards Sarah Heller1,2,5,6, Neelendra K. Joshi1,2,3,6*, Timothy Leslie4, Edwin G. Rajotte2 & David J. Biddinger1,2* Natural habitats, comprised of various fowering plant species, provide food and nesting resources for pollinator species and other benefcial arthropods. Loss of such habitats in agricultural regions and in other human-modifed landscapes could be a factor in recent bee declines. Artifcially established foral plantings may ofset these losses. A multi-year, season-long feld study was conducted to examine how wildfower plantings near commercial apple orchards infuenced bee communities. We examined bee abundance, species richness, diversity, and species assemblages in both the foral plantings and adjoining apple orchards. We also examined bee community subsets, such as known tree fruit pollinators, rare pollinator species, and bees collected during apple bloom. During this study, a total of 138 species of bees were collected, which included 100 species in the foral plantings and 116 species in the apple orchards. Abundance of rare bee species was not signifcantly diferent between apple orchards and the foral plantings. During apple bloom, the known tree fruit pollinators were more frequently captured in the orchards than the foral plantings. However, after apple bloom, the abundance of known tree fruit pollinating bees increased signifcantly in the foral plantings, indicating potential for foral plantings to provide additional food and nesting resources when apple fowers are not available. Insect pollinators are essential in nearly all terrestrial ecosystems, and the ecosystem services they provide are vital to both wild plant communities and agricultural crop production. -
