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. -
The Chemical Ecology and Evolution of Bee–Flower Interactions: a Review and Perspectives1
668 REVIEW / SYNTHE` SE The chemical ecology and evolution of bee–flower interactions: a review and perspectives1 S. Do¨ tterl and N.J. Vereecken Abstract: Bees and angiosperms have shared a long and intertwined evolutionary history and their interactions have re- sulted in remarkable adaptations. Yet, at a time when the ‘‘pollination crisis’’ is of major concern as natural populations of both wild and honey bees (Apis mellifera L., 1758) face alarming decline rates at a worldwide scale, there are important gaps in our understanding of the ecology and evolution of bee–flower interactions. In this review, we summarize and dis- cuss the current knowledge about the role of floral chemistry versus other communication channels in bee-pollinated flow- ering plants, both at the macro- and micro-evolutionary levels, and across the specialization–generalization gradient. The available data illustrate that floral scents and floral chemistry have been largely overlooked in bee–flower interactions, and that pollination studies integrating these components along with pollinator behaviour in a phylogenetic context will help gain considerable insights into the sensory ecology and the evolution of bees and their associated flowering plants. Re´sume´ : Les abeilles et les angiospermes partagent une grande partie de leur histoire e´volutive, et leurs interactions ont produit de remarquables exemples d’adaptations mutuelles. Cependant, a` une e´poque ou` la « crise de la pollinisation » de- vient une pre´occupation majeure et ou` les populations d’abeilles sauvages et mellife`res (Apis mellifera L., 1758) font face a` des de´clins massifs a` l’e´chelle mondiale, notre compre´hension de l’e´cologie et de l’e´volution des relations abeilles- plantes demeure fragmentaire. -

Bees and Wasps of the East Sussex South Downs
A SURVEY OF THE BEES AND WASPS OF FIFTEEN CHALK GRASSLAND AND CHALK HEATH SITES WITHIN THE EAST SUSSEX SOUTH DOWNS Steven Falk, 2011 A SURVEY OF THE BEES AND WASPS OF FIFTEEN CHALK GRASSLAND AND CHALK HEATH SITES WITHIN THE EAST SUSSEX SOUTH DOWNS Steven Falk, 2011 Abstract For six years between 2003 and 2008, over 100 site visits were made to fifteen chalk grassland and chalk heath sites within the South Downs of Vice-county 14 (East Sussex). This produced a list of 227 bee and wasp species and revealed the comparative frequency of different species, the comparative richness of different sites and provided a basic insight into how many of the species interact with the South Downs at a site and landscape level. The study revealed that, in addition to the character of the semi-natural grasslands present, the bee and wasp fauna is also influenced by the more intensively-managed agricultural landscapes of the Downs, with many species taking advantage of blossoming hedge shrubs, flowery fallow fields, flowery arable field margins, flowering crops such as Rape, plus plants such as buttercups, thistles and dandelions within relatively improved pasture. Some very rare species were encountered, notably the bee Halictus eurygnathus Blüthgen which had not been seen in Britain since 1946. This was eventually recorded at seven sites and was associated with an abundance of Greater Knapweed. The very rare bees Anthophora retusa (Linnaeus) and Andrena niveata Friese were also observed foraging on several dates during their flight periods, providing a better insight into their ecology and conservation requirements. -

Aculeate Bee and Wasp Survey Report 2015/16 for the Knepp Wildland Project
Aculeate bee and wasp survey report 2015/16 for the Knepp Wildland Project Thomas Wood and Dave Goulson School of Life Sciences, The University of Sussex, Falmer, BN1 9QG Methodology Aculeate bees and wasps were surveyed on the Knepp Castle Estate as part of their biodiversity monitoring programme during the 2015/2016 seasons. The southern block, comprising 473 hectares, was selected for the survey as it is the most extensively rewilded section of the estate. Nine areas were identified in the southern block and each one was surveyed by free searching for 20 minutes on each visit. Surveys were conducted on April 13th, June 3rd and June 30th in 2015 and May 20th, June 24th, July 20th, August 7th and August 12th in 2016. Survey results and species of note A total of 62 species of bee and 30 species of wasp were recorded during the survey. This total includes seven bee and four wasp species of national conservation importance (Table 1, Table 2). Rarity classifications come from Falk (1991) but have been modified by TW to take account of the major shifts in abundance that have occurred since the publication of this review. The important bee species were Andrena labiata, Ceratina cyanea, Lasioglossum puncticolle, Macropis europaea, Melitta leporina, Melitta tricincta and Sphecodes scabricollis. Both A. labiata and C. cyanea show no particular affinity for clay. Both forage from a wide variety of plants and are considered scarce nationally for historical reasons and for their restricted southern distribution. M. leporina and M. tricincta are both oligolectic bees, collecting pollen from one botanical family only. -

Volume 8. No. 2 (Autumn 2000)
The CARLISLE NATURALIST The Carlisle Naturalist From the Editor Volume 8 Number 2 Autumn 2000 My apologies for the late appearance of this issue of the Carlisle Naturalist, once again brought on by the backlog of work caused by the development of a temporary Published twice-yearly (Spring/Autumn) by Carlisle Natural History Society exhibition. On this occasion the subject is the minerals of Cumbria. The show, “Mineral Magic”, is on display until 21st January in the Special Exhibitions Gallery at ISSN 1362-6728 Tullie House. If you have not already visited the exhibition it is worth seeing for the fine collection of colourful and spectacular crystals mined in Cumbria. Since this ‘Autumn’ issue is now so late, I can take the opportunity to wish all members of the Society a very Happy New Year. Winter Amusement Are you wondering what you can do to contribute to the furtherance of natural history knowledge this winter? Well, here is a suggestion for those of you with at least a stereo microscope. In the world of microfungi there are a number of species that parasitise other fungi. Some research is going on in the UK and in mainland Europe on a strange, undescribed, species in the genus Unguiculariopsis. This fungus grows on minute pyrenomycetes that develop on Rabbit and Hare dung. All you need is somewhere to incubate Rabbit ‘pills’ in a damp atmosphere. I have some Petri dishes available if anyone is interested in this project. Leave the ‘pills’ in a light location, and not too warm, damping them occasionally and just watch them, say, weekly. -

Ebmer2, Fritz Gusenleitner3 and Maximilian Schwarz4 With 65 Figures Accepted: 28. October 2016 Summary: During studies in floral ecology 151 bee (Apidae) species from 25 genera were recorded in the Botanic Garden of the Karl-Franzens-Universität Graz since 1981. The garden covers an area of c. 3.6 ha (buildings included). The voucher specimens are listed by date, gender and plant species visited. For a part of the bee species additional notes are presented. The most elaborated notes concern Hylaeus styriacus, three species of Andrena subg. Taeniandrena (opening of floral buds for pollen harvest,slicing calyx or corolla for reaching nectar), Andrena rufula, Andrena susterai, Megachile nigriventris on Glau cium, behaviour of Megachile willughbiella, Eucera nigrescens (collecting on Symphytum officinale), Xylocopa violacea (vibratory pollen collection, Xylocopa-blossoms, nectar robbing), Bombus haematurus, Nomada trapeziformis, behaviour of Lasioglossum females, honeydew and bumblebees as well as the flowers ofViscum , Forsythia and Lysimachia. Andrena gelriae and Lasioglossum setulosum are first records for Styria. This inventory is put in a broader context by the addition of publications with enumerations of bees for 23 other botanic gardens of Central Europe, of which few are briefly discussed.
