  • 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.

  • Entertainment-Education in Science Education Available on Mobile Devices Interactive Tasks Allow You to Quickly Verify the Acquired Knowledge
    Entertainment-education in science education the monograph edited by Grzegorz Karwasz & Małgorzata Nodzyńska 1 2 Entertainment-education in science education the monograph edited by Grzegorz Karwasz & Małgorzata Nodzyńska TORUŃ 2017 3 The monograph edited by: Grzegorz Karwasz & Małgorzata Nodzyńska Rewievers: Cover: Ewelina Kobylańska ISBN .......... 4 Introduction Jan Amos Komensky in „Great Didactics” (Amsterdam, 1657) defined didactics not as a mere process of teaching, but as teaching efficient, lasting and pleasant. He wrote (p. 131) “The school itself should be a pleasant place, and attractive to the eye both within and without. […] If this is done, boys will, in all probability, go to school with as much pleasure as to fairs, where they always hope to see and hear something new.” Further (p. 167) Komensky added: “The desire to know and to learn should be excited in boys in every possible manner.” The idea of linking the fun with didactics finds many followers, expressed also in tittles of activities like “Science is Fun” or “Physics is Fun”. In (Karwasz, Kruk, 2012) we defined three complementary aspects of any bit of information (an exhibition object, a film, a lecture): entertainment (“ludico” in Italian), didactics, and science. The first aspect gives an impression to a student/ visitor/ listener: “how funny it is!”. The didactical aspect induces: “How simple it is!” And the aspect of scientific curiosity induces in best students a question: “How complex it is!” These three functions add-up like three basic colors to give a full spectrum of enlightenment. The entertainment function can be performed in different forms – school, extra-school, complementary to school.

  • Bumble Bees of the Susa Valley (Hymenoptera Apidae)
    Bulletin of Insectology 63 (1): 137-152, 2010 ISSN 1721-8861 Bumble bees of the Susa Valley (Hymenoptera Apidae) Aulo MANINO, Augusto PATETTA, Giulia BOGLIETTI, Marco PORPORATO Di.Va.P.R.A. - Entomologia e Zoologia applicate all’Ambiente “Carlo Vidano”, Università di Torino, Grugliasco, Italy Abstract A survey of bumble bees (Bombus Latreille) of the Susa Valley was conducted at 124 locations between 340 and 3,130 m a.s.l. representative of the whole territory, which lies within the Cottian Central Alps, the Northern Cottian Alps, and the South-eastern Graian Alps. Altogether 1,102 specimens were collected and determined (180 queens, 227 males, and 695 workers) belonging to 30 species - two of which are represented by two subspecies - which account for 70% of those known in Italy, demonstrating the particular value of the area examined with regard to environmental quality and biodiversity. Bombus soroeensis (F.), Bombus me- somelas Gerstaecker, Bombus ruderarius (Mueller), Bombus monticola Smith, Bombus pratorum (L.), Bombus lucorum (L.), Bombus terrestris (L.), and Bombus lapidarius (L.) can be considered predominant, each one representing more than 5% of the collected specimens, 12 species are rather common (1-5% of specimens) and the remaining nine rare (less than 1%). A list of col- lected specimens with collection localities and dates is provided. To illustrate more clearly the altitudinal distribution of the dif- ferent species, the capture locations were grouped by altitude. 83.5% of the samples is also provided with data on the plant on which they were collected, comprising a total of 52 plant genera within 20 plant families.

    sustainability Article Unique Bee Communities within Vacant Lots and Urban Farms Result from Variation in Surrounding Urbanization Intensity Frances S. Sivakoff ID , Scott P. Prajzner and Mary M. 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.

  • Bee-Plant Networks: Structure, Dynamics and the Metacommunity Concept
    Ber. d. Reinh.-Tüxen-Ges. 28, 23-40. Hannover 2016 Bee-plant networks: structure, dynamics and the metacommunity concept – Anselm Kratochwil und Sabrina Krausch, Osnabrück – Abstract Wild bees play an important role within pollinator-plant webs. The structure of such net- works is influenced by the regional species pool. After special filtering processes an actual pool will be established. According to the results of model studies these processes can be elu- cidated, especially for dry sandy grassland habitats. After restoration of specific plant com- munities (which had been developed mainly by inoculation of plant material) in a sandy area which was not or hardly populated by bees before the colonization process of bees proceeded very quickly. Foraging and nesting resources are triggering the bee species composition. Dis- persal and genetic bottlenecks seem to play a minor role. Functional aspects (e.g. number of generalists, specialists and cleptoparasites; body-size distributions) of the bee communities show that ecosystem stabilizing factors may be restored rapidly. Higher wild-bee diversity and higher numbers of specialized species were found at drier plots, e.g. communities of Koelerio-Corynephoretea and Festuco-Brometea. Bee-plant webs are highly complex systems and combine elements of nestedness, modularization and gradients. Beside structural com- plexity bee-plant networks can be characterized as dynamic systems. This is shown by using the metacommunity concept. Zusammenfassung: Wildbienen-Pflanzenarten-Netzwerke: Struktur, Dynamik und das Metacommunity-Konzept.
