Field studies and theoretical analysis of plant-pollinator 18 interaction networks typically focus on the partitioning of the floral community 19 between pollinator species, with little attention paid to intraspecific variation 20 among plants or foraging bees. In other systems, male and female animals 21 exhibit different, cascading, impacts on interaction partners. -

Cho đến nay, trên 20.000 loài thuộc 7 họ (Andrenidae, Apidae, Colletidae, Halictidae, Megachilidae, Melittidae và Stenotritidae) đã được mô tả trên thế giới (Ascher và Pickering, 2020). Ong mật được đánh giá là một trong những trợ thủ đắc lực cho quá trình thụ phấn cho các loài thực vật có hoa. Cụ thể, chúng tiến hành thụ phấn cho nhiều loại lương thực, thực phẩm thiết yếu cũng như các loại cây ăn quả quan trọng của nước ta như lúa, ngô, đậu, dưa, nhãn, vải hay bưởi,… Với khả năng thụ phấn tốt, chúng giúp năng suất cây trồng tăng lên 20-30 % so với thông thường, thậm chí là 50 % (Phạm Hồng Thái, 2014). Ngoài ra, một số các loài Ong mật đã được thuần nuôi và mang lại lợi ích kinh tế rất cao cho người nuôi ong bằng việc khai thác các sản phẩm được tạo ra bởi chúng như phấn hoa, sáp ong, sữa ong chúa, đặc biệt là mật ong. -

Unique Bee Communities Within Vacant Lots and Urban Farms Result from Variation in Surrounding Urbanization Intensity
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. -
Changes in Composition and Structure of a Wild Bee Community and Plant- Pollinator Interactions in South-Central Ontario Over a Forty-Nine Year Period
Changes in composition and structure of a wild bee community and plant- pollinator interactions in South-Central Ontario over a forty-nine year period by Claire Rubens A thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Environmental Sciences Guelph, Ontario, Canada © Claire Rubens, September 2019 ABSTRACT CHANGES IN COMPOSITION AND STRUCTURE OF A WILD BEE COMMUNITY AND PLANT-POLLINATOR INTERACTIONS IN SOUTH-CENTRAL ONTARIO OVER A FORTY-NINE YEAR PERIOD Claire Rubens Advisor: University of Guelph, 2019 Professor Nigel E. Raine Wild pollinators provide important ecosystem services for both agricultural and natural ecosystems. While there is evidence of global pollinator declines, more long-term studies are needed to assess population trends, and the potential impacts of environmental stress factors such as land-use intensification and climate change. This is the first study to examine long-term changes in a wild bee community in Canada. Wild bee abundance, species richness, diversity and evenness were compared across three sampling periods (1968-1969, 2002-03, and 2016-17) in Caledon, Ontario over 49 years. Despite decreases in wild bee abundance since 2002-03, the diversity, evenness and richness increased over time. Extensive restructuring (including loss and frequency changes) of plant-pollinator interactions from 2002-03 to 2016-17 appeared not to affect network resilience. While local trends in land-use patterns did not predict changes in this wild bee community, climatic changes in temperature and snowfall correlated with wild bee abundance at the site. iii ACKNOWLEDGEMENTS I would like to thank my advisor Dr. -

The agriculture development in the Suez Canal region is receiving a great deal of attention in Egypt, thus, the diversity of solitary bees are essential for high quality production of seeds, vegetables, and fruit. The objective of this study was to evaluate the biodiversity of solitary bee populations around the Canal region. About 900 - 1000 specimens of bees were collected from different locations of the Ismailia, Suez, and Sinai Governorates. Fifty-five species of bees were identified. With the exception of Melittidae family, all the bee families were present in the Canal region. The total number of species for each family were 7, 9, 11, 13, and 15 species for Andrenidae, Colletidae, Apidae, Halictidae, and Megachilidae, respectively. Lasioglossum mandibularie (Morawitz, 1866) is a newly recorded species collected from Egypt. In the Suez Canal region, the most abundant species found with large populations were Andrena ovatula ssp. ovatula (Kirby, 1802), Ceratina tarsata Morawitz, 1872, and Colletes lacunatus Dours, 1872. -

Floral Relatioships of Bees in Selected Areas of Sri Lanka
Cey. J. Sci. (Bio. Sci.) Vol. 34,2005,27-45 FLORAL RELATIOSHIPS OF BEES IN SELECTED AREAS OF SRI LANKA W. A. Inoka P. Karunaratne, Jayanthi P. Edirisinghe* and C. V. Savithri Gunatilleke1 Department of Zoology, 'Department of Botany, Faculty of Science, University of Peradeniya, Peradeniya, SriLanka. ABSTRACT This study represents the very first attempt to record the floral relations of bees of Sri Lanka. Floral hosts of 117 bee species in 35 genera were recorded based on floral visits, pollen carriage and special behaviour at flowers. Floral hosts comprised 154 plant species in 112 genera and 44 families. Majority of the floral hosts were native plants of which most were weeds in their respective habitats. The exotic naturalized weed, Hyptis suaveolense was exceptional in attracting 60 bee species. All five species of social bees and majority of the solitary bees were polylectics foraging on pollen of a variety of unrelated flowers. Seven solitary bee species were recognized as oligolectics foraging on species of Convolvulaceae and Malvaceae having large spiny pollen. Sonication at tubular anthers of certain Solanaceae and Melastomataceae flowers having concealed pollen was observed in 12 species of solitary bees. Nectar robbing by males of five species of solitary bees was recorded from certain tubular-shaped flowers. Floral relationships suggest that most bees are generalists and a few have become specialized to forage on specific groups of flowers. The information gathered would be useful in pollination studies and in the management and conservation of bees.

DOI: http://dx.doi.org/10.26842/binhm.7.2018.15.1.0057 July, (2018) 15 (1): 57-75 STUDY ON DIVERSITY OF BEES (HYMENOPTERA, APOIDEA) FROM DIFFERENT REGIONS OF IRAQ Razzaq Shalan Augul Iraq Natural History Research Center and Museum, University of Baghdad, Baghdad, Iraq Corresponding author: [email protected], [email protected] Received Date: 11 February 2018 Accepted Date:06 March 2018 ABSTRACT The fauna of bees (Hymenoptera, Apoidea) from different regions of Iraq is surveyed in this study; there were 16 species, 13 genera that belong to four families which are collected in this investigation. Also, all the species that are recorded for Iraq in previous investigations are revised; totally there are 110 species, 32 genera belonging to five families: Apidae, Andernidae, Colletidae, Halictidae and Megachilidae were listed. Key words: Apoidea, Bees, Diversity, Fauna, Hymenoptera, Iraq. INTRODUCTION The higher classification of bees has changed recently; Gauld and Bolton (1988) recognized only two families, Sphecidae and Apidae in the superfamily Apoidea, they classified all bees within Apidae in different subfamilies; whereas Michener (1993) recognized 11 families of bees within an informal series Apiformis of Apoidea: Apidae, Andrenidae, Anthophoridae, Colletidae, Ctenoplectidae, Fidellidae, Halictidae, Megachilidae, Melittidae, Oxaeidae and Stenotritidae; but later reduced the number of families to seven by Michener (2000, 2007), these families included: Melittidae, Megachilidae, Apidae, Andrenidae, Colletidae, Stenotritidae, and Halictidae. Bees are thought to have played an important role in the diversification of the angiosperms in the early to mid-Cretaceous (Grimaldi, 1999); and also they played a role with other insect′s pollination in ecosystem service: fruits, vegetables or seeds production from 87 of the 115 leading global food crops depend upon animal pollination (Klein et al., 2007). -

This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract Citizen science engages members of the nonscientific community in academic research, contributing to our collective knowledge of the natural environment through biological monitoring and environmental observations. Observation plots are often used to assess pollinator diversity and abundance in citizen science monitoring programs. To ensure that data collected are reliable, citizen observations should be evaluated against controlled scientific studies. I designed this project to assess the accuracy of citizen observations of bees in order to enhance the efficacy of PollinatorWatch, a Canadian pollinator monitoring program. PollinatorWatch engages volunteers in collecting observational data on bees visiting flowers but the program‘s effectiveness at reporting on bee faunal information has not been evaluated. Specifically, I was interested in determining how PollinatorWatch could be standardized to validate the efforts of participants. Research took place in mixed meadow habitats at two urban conservation areas, the Royal Botanical Gardens in Burlington, ON and the rare Charitable Research Reserve in Cambridge, ON.
