  • 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.

  • The Bees of Sub-Saharan Africa
    A-PDF Split DEMO : Purchase from www.A-PDF.com to remove the watermark Genus Nasutapis Michener (Fig. 36E) Nasutapis has a distinct projection medioventrally on the clypeus. This genus is monotypic (Nasutapis straussorum Michener) and endemic to KwaZulu-Natal, South Africa, and found in nests of Braunsapis facialis (Gerstaecker). 8.6.2. Subfamily Nomadinae In sub-Saharan Africa the Nomadinae comprises four tribes and six genera. They are all cleptoparasitic. Diagnostic features for the subfamily are difficult to define, but almost each tribe has a distinctive feature, except Ammobatoidini. 8.6.2.1. Tribe Nomadini Genus Nomada Scopoli (Fig. 37A) Nomadini has one genus in sub-Saharan Africa, namely Nomada. There are ten species, occurring mostly in North-East and southern Africa. 8.6.2.2. Tribe Epeolini Genus Epeolus Latreille (Fig. 37B) Epeolini has one genus in sub-Saharan Africa, namely Epeolus. There are 13 species that occur mostly on the east side of the continent, along its entire length. 8.6.2.3. Tribe Ammobatoidini Genus Ammobatoides Radoszkowski (Fig. 37C) Ammobatoidini has one genus in sub-Saharan Africa, and it is known only from the holotype of Ammobatoides braunsi Bischoff. It was collected in Willowmore, South Africa. It therefore goes without saying that it is extremely rare. 8.6.2.4. Tribe Ammobatini The Ammobatini has four sub-Saharan genera. They all comprise cleptoparasitic bees. Ammobates has its centre of diversity in the Palaearctic, as does Chiasmognathus, which occurs just north of the Afrotropical Region and intrudes into sub-Saharan Africa. Pasites is mostly Afrotropical and Sphecodopsis is endemic to southern Africa.

  • Phylogeny of the Ammobatini and Revision of the Afrotropical Genera (Hymenoptera: Anthophoridae: Nomadinae)
    PHYLOGENY OF THE AMMOBATINI AND REVISION OF THE AFROTROPICAL GENERA (HYMENOPTERA: ANTHOPHORIDAE: NOMADINAE) by CONNAL DESMOND EARDLEY Submitted in fulfilment of the academic requirements for the degree of Doctor of Philosophy in the Department of Zoology and Entomology University of Natal Pietermaritzburg 1994 ABSTRACT The phylogeny of the Ammobatini was studied, with regard to the principles of cladistics using parsimony, and the classification is revised. It is concluded that the tribe fonns a monophyletic group that comprises six distinct monophyletic genera: Pasite Jurine, Sphecodopsis Bischoff, Ammobates Latreille, Me/anempis Saussure, Spilwpasites Warncke and Oreopasites Cockerell, of which Pasites, Sphecodopsis, Ammobates and MeLanempis occur in the Afrotropical Region. The Afrotropical species of these four genera are revised. Pseudopasites Bischoff and Pseudodichroa Bischoff are synonymized with Sphecodopsis. Pasites includes 17 Afrotropical species, Sphecodopsis 10 species, and Ammobates and MeLanempis are each known from a single Afrotropical species. Ten new species are described: Pa..~ites nilssoni, P. paulyi, P. humecta, P. glwma, P. namibiensis, P. somaLica, Sphecodopsis vespericena, S. longipygidium, S. namaquensis and Ammobates auster. Thirty-three names are synonymized: they are P. nigerrima (Friese), P. argentata (Baker) (= P. barkeri (Cockereil»; P. chubbi Cockerell, P. nigritula Bischoff, P. peratra Cockerell (= P. atra Friese); P. nigripes (Friese), P. fortis Cockerell, P. subfortis Cockerell, P. stordyi Cockerell, P. voiensis Cockerell, P. aitior Cockerell (= P. carnifex (Gerstaecker»; P. Ilataiensis (Cockerell), P. aiboguttatus (Friese), P. ogiiviei (Cockerell) (= P. jenseni (Friese»; P. alivalensis (Cockerell), P. rufitarsis (Cockerell) (= P. histrio (Gerstaecker»; P. marshaUi (Cockerell) (= P. jonesi (Cockerell»; P. abessinica (Friese), P. fulviventris (Bischoff), P. rhodesialla (Bischoff), P. apicalis (Bischoff), P.

  • Food Load Manipulation Ability Shapes Flight Morphology in Females Of
    Polidori et al. Frontiers in Zoology 2013, 10:36 http://www.frontiersinzoology.com/content/10/1/36 RESEARCH Open Access Food load manipulation ability shapes flight morphology in females of central-place foraging Hymenoptera Carlo Polidori1*, Angelica Crottini2, Lidia Della Venezia3,5, Jesús Selfa4, Nicola Saino5 and Diego Rubolini5 Abstract Background: Ecological constraints related to foraging are expected to affect the evolution of morphological traits relevant to food capture, manipulation and transport. Females of central-place foraging Hymenoptera vary in their food load manipulation ability. Bees and social wasps modulate the amount of food taken per foraging trip (in terms of e.g. number of pollen grains or parts of prey), while solitary wasps carry exclusively entire prey items. We hypothesized that the foraging constraints acting on females of the latter species, imposed by the upper limit to the load size they are able to transport in flight, should promote the evolution of a greater load-lifting capacity and manoeuvrability, specifically in terms of greater flight muscle to body mass ratio and lower wing loading. Results: Our comparative study of 28 species confirms that, accounting for shared ancestry, female flight muscle ratio was significantly higher and wing loading lower in species taking entire prey compared to those that are able to modulate load size. Body mass had no effect on flight muscle ratio, though it strongly and negatively co-varied with wing loading. Across species, flight muscle ratio and wing loading were negatively correlated, suggesting coevolution of these traits. Conclusions: Natural selection has led to the coevolution of resource load manipulation ability and morphological traits affecting flying ability with additional loads in females of central-place foraging Hymenoptera.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Andrena, which is the largest genus in the Andrenidae, is a very important genus for the pollination of fruit trees. Andrena flavipes Panzer is one of the most common species observed in the study area and can continue the flight activity even under low temperature. In this study, the pollen collected by A. flavipes was determined. In addition, the potential to carry sweet cherry pollen of the aforementioned species was also researched. For the pollen preparates, the scopae of 34 females were used. As a result of the diagnosis studies, it was determined that A. flavipes species collected the pollens of 13 families and that the dominant pollen group belonged to the Brassicaceae. It was ascertained that A. flavipes collected sweet cherry pollen and that the sweet cherry flowers do not represent a primary pollen source, however.

  • First Observations on Nesting and Immatures of the Bee Genus Ancyla (Apoidea: Apidae: Apinae: Ancylaini)
    AMERICAN MUSEUM NOVITATES Number 3749, 24 pp. June 25, 2012 First Observations on Nesting and Immatures of the Bee Genus Ancyla (Apoidea: Apidae: Apinae: Ancylaini) JAKUB STRAKA1 AND JEROME G. RoZEN, JR.2 ABSTRACT Herein we present information on the nest architecture and nesting biology primarily of Ancyla asiatica Friese and, to a lesser extent, of A. anatolica Warncke, both found near Adana, Turkey. These two ground-nesting species visit Apiaceae for mating and larval provisions, with A. asiatica going to Daucus carota and A. anatolica, to Eryngium. The cocoon of A. asiatica is described in detail as are the mature oocytes of both species and the pre- and postdefecating larvae of A. asiatica. Each site was attacked by a separate, unnamed cleptoparasitic species of Ammobates (Nomadinae). The relationships of the Ancylaini to other apine tribes are discussed based on their mature larvae, and a revised tribal key to mature larvae of nonparasitic, noncor- biculate Apinae is presented. INTRODUCTION Of all tribes of nonparasitic Apidae, the natural history of the Ancylaini3 has been the least investigated. Until now, nothing has been recorded concerning the nests of any species, 1 Department of Zoology, Faculty of Science, Charles University in Prague, CZ-12844 Prague 2, Czech Republic. 2 Division of Invertebrate Zoology, American Museum of Natural History. 3 The spelling of tribe Ancylini Michener, 1944, has recently been emended to Ancylaini to remove hom- onymy with Ancylini Rafinsque, 1815 (Mollusca, Gastropoda) (Engel et al., 2010: ICZN Ruling (Opinion 2246-Case 3461).

  • A New Species of Amegilla from Northeastern Egypt (Hymenoptera: Apidae)
    ©Biologiezentrum Linz/Austria; download unter www.biologiezentrum.at Linzer biol. Beitr. 39/2 821-828 18.12.2007 A new species of Amegilla from northeastern Egypt (Hymenoptera: Apidae) M.S. ENGEL A b s t r a c t : A new bee species of the genus Amegilla (Apinae: Anthophorini) is described and figured from northeastern Egypt. Amegilla argophenax nov.sp., belongs to the A. fasciata group and is most similar to A. deceptrix (PRIESNER) nov.comb. which occurs in the same region. Characters are provided to distinguish the species from its congeners. Podalirius pyramidalis KIRBY, from Socotra (Republic of Yemen), is resurrected from synonymy under Amegilla albigena (LEPELETIER DE SAINT FARGEAU) (as A. pyramidalis nov.comb.) where it is, like A. argophenax and A. deceptrix, a member of the A. fasciata group. K e y w o r d s : Anthophila, Apoidea, Africa, Anthophorini, Arabia, Socotra, taxonomy. 1. Introduction The genus Amegilla is a diverse group of approximately 255 anthophorine bee species distributed in southern Europe and the Mediterranean basin, southward throughout Africa and Madagascar, east into Arabia and in Asia as far as northeast China, Korea, and Japan, and south into Sri Lanka, Indonesia, New Guinea, as well as Australia, Tas- mania, and the Solomon Islands (MICHENER 2000). While the genus has received the attention of various authors (e.g., RAYMENT 1942, 1947, 1951; LIEFTINCK 1956, 1975; PRIESNER 1957; EARDLEY 1994), exceedingly similar or even cryptic coloration nonetheless continues to plague the taxonomy and identification of species, a situation further exacerbated by low sample sizes in most collections. The purpose of the present contribution is to provide the description of a new species of Amegilla from northeastern Egypt (Figs 1-2) and correct the status of two from the gene- ral region of northeastern Africa and Arabia, particularly one that is closely allied to the species described herein.
